Educational interventions to improve bowel cancer awareness and screening in Organisation for Economic Co-operation and Development countries: A scoping review. Prev Med Rep 2024; 39:102653. [PMID: 38384964 PMCID: PMC10879007 DOI: 10.1016/j.pmedr.2024.102653] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 01/29/2024] [Accepted: 02/07/2024] [Indexed: 02/23/2024] Open
Abstract
Objectives Summarise theory informed educational interventions for improving bowel cancer awareness and screening. Methods A search was conducted in PubMed, EMBASE, Web of Science and CINAHL. English studies from 2016 to 2022 which implemented community-based bowel cancer awareness and/or screening education interventions for adults in Organisation for Economic Co-operation and Development countries were included. Results Sixty-two studies were included, 32 measured both screening and awareness (24 measured screening only, 6 measured awareness only). Education interventions were grouped and summarised in five education types: lay community health education/counselling (n = 28), education material (n = 5), health professional education/counselling (n = 10), mass media (n = 5) and other (n = 19). Other included education interventions which did not fit into the four types previously mentioned. Six studies tested more than one education type. Each type within these studies were reported/summarised separately within the appropriate education type. Lay educators resulted in improved awareness and screening. Brochures were effective education materials for screening and combined with lay educators resulted in increased awareness. State-wide mass media campaigns significantly improved screening uptake for up to 2-months post-campaign. Fear and loss-framed messaging improved screening intentions compared to humour or gain-based messaging. Decision aids had limited improvements in awareness. Facebook campaign and telephone counselling had limited improvements in screening. Conclusions Lay community health educators, brochures, and mass media campaigns occurring multiple times a year may be effective interventions in improving screening and/or awareness. Such approaches should be considered when developing community education. Education interventions should include multiple components suggested above to maximise improvements of awareness and screening.

Impact of organised colorectal cancer screening on age-specific population incidences: evidence from a quasi-experimental study in Sweden. Eur J Epidemiol 2024; 39:87-96. [PMID: 38177571 PMCID: PMC10810926 DOI: 10.1007/s10654-023-01073-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Accepted: 10/26/2023] [Indexed: 01/06/2024]
Abstract
Colorectal cancer (CRC) incurs a significant disease burden globally. Organised CRC screening programmes have been widely implemented for early detection and prevention. To understand the public health impact of these programmes, quantitative evidence of changes in overall and age-specific population incidences is fundamental. We aimed to provide such evidence by exploiting a time lag in the implementation of organised screening in Sweden: two out of 21 regions (these two regions comprise nearly 20% of the total Swedish population) have offered organised screening since 2008; the other regions have offered CRC screening since 2021. Using registry data on diagnosed CRC cases and socio-demographics for all regions in Sweden over the period 1970-2019, Bayesian structural time series modelling and difference-in-differences were applied to analyse the impact of screening on age-specific population incidences over time (CRC cases per 100.000 persons/year). After inviting birth-year cohorts aged 60-69 years for stool-based testing, the incidence rate in the 70-74-year age group decreased significantly over time, with an average reduction of - 44·40 (95% CI - 58·15 to - 31·31) from 2011 to 2019 in the intervention regions. In the overall population aged 60-74 years, there was a net incidence decrease of - 7·99 (95% CI - 13·85 to - 2·39) since the initiation of organised screening in the intervention regions (2008-2019). Organised CRC screening for 60-69-year-olds generated a change in age-specific incidence patterns with a long-lasting incidence decrease in the 70-74-year-old population, implying reductions in the excess mortality and burden of the disease.

Low Incidence of Colorectal Advanced Neoplasia During Surveillance in Individuals with a Family History of Colorectal Cancer. Dig Dis Sci 2023; 68:4243-4251. [PMID: 37682374 PMCID: PMC10570165 DOI: 10.1007/s10620-023-08053-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Accepted: 07/21/2023] [Indexed: 09/09/2023]
Abstract
BACKGROUND Family history of colorectal cancer (CRC) is used to stratify individuals into risk categories which determine timing of initial screening and ongoing CRC surveillance. Evidence for long-term CRC risk following a normal index colonoscopy in family history populations is limited. AIMS To assess the incidence of advanced neoplasia and associated risk factors in a population undergoing surveillance colonoscopies due to family history of CRC. METHODS Surveillance colonoscopy findings were examined in 425 individuals with a family history of CRC, a normal index colonoscopy and a minimum of 10 years of follow-up colonoscopies. Advanced neoplasia risk was determined for three CRC family history categories (near-average, medium and high-risk), accounting for demographics and time after the first colonoscopy. RESULTS The median follow-up was 13.5 years (IQR 11.5-16.0), with an incidence of advanced neoplasia of 14.35% (61/425). The number of affected relatives and age of CRC diagnosis in the youngest relative did not predict the risk of advanced neoplasia (p > 0.05), with no significant differences in advanced neoplasia incidence between the family history categories (p = 0.16). Patients ≥ 60 years showed a fourfold (HR 4.14, 95% CI 1.33-12.89) higher advanced neoplasia risk during surveillance than those < 40 years at index colonoscopy. With each subsequent negative colonoscopy, the risk of advanced neoplasia at ongoing surveillance was reduced. CONCLUSIONS The incidence of advanced neoplasia was low (14.35%), regardless of the family history risk category, with older age being the main risk for advanced neoplasia. Delaying onset of colonoscopy or lengthening surveillance intervals could be a more efficient use of resources in this population.

Implementation of risk stratification within bowel cancer screening: a community jury study exploring public acceptability and communication needs. BMC Public Health 2023; 23:1798. [PMID: 37715213 PMCID: PMC10503141 DOI: 10.1186/s12889-023-16704-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Accepted: 09/05/2023] [Indexed: 09/17/2023] Open
Abstract
BACKGROUND Population-based cancer screening programmes are shifting away from age and/or sex-based screening criteria towards a risk-stratified approach. Any such changes must be acceptable to the public and communicated effectively. We aimed to explore the social and ethical considerations of implementing risk stratification at three different stages of the bowel cancer screening programme and to understand public requirements for communication. METHODS We conducted two pairs of community juries, addressing risk stratification for screening eligibility or thresholds for referral to colonoscopy and screening interval. Using screening test results (where applicable), and lifestyle and genetic risk scores were suggested as potential stratification strategies. After being informed about the topic through a series of presentations and discussions including screening principles, ethical considerations and how risk stratification could be incorporated, participants deliberated over the research questions. They then reported their final verdicts on the acceptability of risk-stratified screening and what information should be shared about their preferred screening strategy. Transcripts were analysed using codebook thematic analysis. RESULTS Risk stratification of bowel cancer screening was acceptable to the informed public. Using data within the current system (age, sex and screening results) was considered an obvious next step and collecting additional data for lifestyle and/or genetic risk assessment was also preferable to age-based screening. Participants acknowledged benefits to individuals and health services, as well as articulating concerns for people with low cancer risk, potential public misconceptions and additional complexity for the system. The need for clear and effective communication about changes to the screening programme and individual risk feedback was highlighted, including making a distinction between information that should be shared with everyone by default and additional details that are available elsewhere. CONCLUSIONS From the perspective of public acceptability, risk stratification using current data could be implemented immediately, ahead of more complex strategies. Collecting additional data for lifestyle and/or genetic risk assessment was also considered acceptable but the practicalities of collecting such data and how the programme would be communicated require careful consideration.

Potential global loss of life expected due to COVID-19 disruptions to organised colorectal cancer screening. EClinicalMedicine 2023; 62:102081. [PMID: 37538541 PMCID: PMC10393619 DOI: 10.1016/j.eclinm.2023.102081] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Revised: 06/14/2023] [Accepted: 06/19/2023] [Indexed: 08/05/2023] Open
Abstract
Background Screening for colorectal cancer (CRC) decreases cancer burden through removal of precancerous lesions and early detection of cancer. The COVID-19 pandemic has disrupted organised CRC screening programs worldwide, with some programs completely suspending screening and others experiencing significant decreases in participation and diagnostic follow-up. This study estimated the global impact of screening disruptions on CRC outcomes, and potential effects of catch-up screening. Methods Organised screening programs were identified in 29 countries, and data on participation rates and COVID-related changes to screening in 2020 were extracted where available. Four independent microsimulation models (ASCCA, MISCAN-Colon, OncoSim, and Policy1-Bowel) were used to estimate the long-term impact on CRC cases and deaths, based on decreases to screening participation in 2020. For countries where 2020 participation data were not available, changes to screening were approximated based on excess mortality rates. Catch-up strategies involving additional screening in 2021 were also simulated. Findings In countries for which direct data were available, organised CRC screening volumes at a country level decreased by an estimated 1.3-40.5% in 2020. Globally, it is estimated that COVID-related screening decreases led to a deficit of 7.4 million fewer faecal screens performed in 2020. In the absence of any organised catch-up screening, this would lead to an estimated 13,000 additional CRC cases and 7,900 deaths globally from 2020 to 2050; 79% of the additional cases and 85% of additional deaths could have been prevented with catch-up screening, respectively. Interpretation COVID-19-related disruptions to screening will cause excess CRC cases and deaths, but appropriately implemented catch-up screening could have reduced the burden by over 80%. Careful management of any disruption is key to improving the resilience of colorectal cancer screening programs.

Socioeconomic differences in expected discomfort from colonoscopy and colon capsule endoscopy. Prev Med 2023:107593. [PMID: 37364794 DOI: 10.1016/j.ypmed.2023.107593] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Revised: 06/12/2023] [Accepted: 06/23/2023] [Indexed: 06/28/2023]
Abstract
Individual income and educational level are associated with participation rates in colorectal cancer screening. We aimed to investigate the expected discomfort from the endoscopic diagnostic modalities of colonoscopy and colon capsule endoscopy in different socioeconomic groups as a potential barrier for participation. In a randomized clinical trial within the Danish colorectal cancer screening program, we distributed questionnaires to 2031 individuals between August 2020 and December 2022 to investigate the expected procedural and overall discomfort from investigations using visual analogue scales. Socioeconomic status was determined by household income and educational level. Multivariate continuous ordinal regressions were performed to estimate the odds of higher expected discomfort. The expected procedural and overall discomfort from both modalities were significantly higher with increasing educational levels and income, except for procedural discomfort from colon capsule endoscopy between income quartiles. The odds ratios for higher expected discomfort increased significantly with increasing educational level, whereas the differences between income groups were less substantial. Bowel preparation contributed most to expected discomfort in colon capsule endoscopy, whereas in colonoscopy, the procedure itself was the largest contributor. Individuals with prior experiences of colonoscopy reported significantly lower expected overall but not procedural discomfort from colonoscopy. The threshold for acceptable discomfort between subgroups is unknown, but the expected discomfort in colon capsule endoscopy and colonoscopy was higher in higher socioeconomic subgroups, suggesting that expected discomfort is not a significant contributor to the inequalities in screening uptake.

Supportive care interventions for managing gastrointestinal symptoms following treatment for colorectal cancer: a systematic review. J Cancer Surviv 2023:10.1007/s11764-023-01403-3. [PMID: 37280309 DOI: 10.1007/s11764-023-01403-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Accepted: 05/09/2023] [Indexed: 06/08/2023]
Abstract
INTRODUCTION Colorectal cancer (CRC) is prevalent in the developed world, with unhealthy lifestyles and diet contributing to rising incidence. Advances in effective screening, diagnosis, and treatments have led to improved survival rates, but CRC survivors suffer poorer long-term gastrointestinal consequences than the general population. However, the current state of clinical practice around provision of health services and treatment options remains unclear. PURPOSE We aimed to identify what supportive care interventions are available to manage gastrointestinal (GI) symptoms for CRC survivors. METHODS We searched Cochrane Central Register of Controlled Trials, Embase, MEDLINE, PsycINFO, and CINAHL from 2000 to April 2022 for resources, services, programs, or interventions to address GI symptoms and functional outcomes in CRC. We extracted information about characteristics of supportive care interventions, the study design, and sample characteristics from included studies, and performed a narrative synthesis RESULTS: Of 3807 papers retrieved, seven met the eligibility criteria. Types of interventions for managing or improving GI symptoms included two rehabilitation, one exercise, one educational, one dietary, and one pharmacological. Pelvic floor muscle exercise may help to resolve GI symptoms more quickly in the post-operative recovery phase. Survivors may also benefit from rehabilitation programs through improved self-management strategies, especially administered soon after completing primary treatment. CONCLUSIONS/IMPLICATIONS FOR CANCER SURVIVORS Despite a high prevalence and burden of GI symptoms post-treatment, there is limited evidence for supportive care interventions to help manage or alleviate these symptoms. More, large-scale randomized controlled trials are needed to identify effective interventions for managing GI symptoms that occur post-treatment.

Bringing fictional characters to life: reflections on co-creating a comic book with members of the public. RESEARCH INVOLVEMENT AND ENGAGEMENT 2023; 9:28. [PMID: 37131245 PMCID: PMC10152719 DOI: 10.1186/s40900-023-00437-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Accepted: 04/18/2023] [Indexed: 05/04/2023]
Abstract
There are growing calls for cancer screening to become more personalised by considering a range of risk factors, rather than a one-size-fits-all, age-based approach. The aim of this public involvement was to co-create a comic book about bowel cancer screening to be used as a visual elicitation tool in research focus groups with members of the public and healthcare professionals, as part of the At Risk study, to discuss their attitudes toward personalised bowel cancer screening, which would involve considering different risk factors. This article critically reflects on the co-creation process to develop the comic book, benefits and challenges, and some lessons learned to inform other researchers considering a similar approach. In total, ten public contributors (5 men and 5 women) from two public involvement networks participated in two successive online workshops to develop six fictional characters, two for each level of bowel cancer risk (low, moderate and high risk). This tool was then used in the At Risk study comprising five focus groups involving 23 participants, including members of the public (n = 12) and healthcare professionals (n = 11). The co-created comic book was a generally well-received research tool able to generate discussion about a complex topic, bowel cancer risk, in an accessible way. It was suggested that the comic book may also be extended beyond the research context to inform bowel cancer screening decisions and raise awareness of risk factors.

Abstract
PURPOSE Many people do not participate in mail-out bowel cancer screening programs due to difficulties using the screening kit. The current study investigated the ways the screening kit could be modified to improve usability. METHODS 1,109 people evaluated 15 different screening kit modifications. Participants reported on how these kit modifications would affect their screening barriers, their future screening intentions, and how much they would recommend that the modification is made to the current screening kit used the program. All responses were given via an online survey conducted between April and December of 2021. RESULTS Seventeen percent of previous NBCSP non-participators indicated that a one-sample test would increase their intention to participate. Recommendation ratings demonstrated higher levels of support for modifications that included providing a barcode naming label (M = 9.06, 95% CI [8.81, 9.31]), having a larger diameter opening of the collection tube (M = 8.42, 95% CI [8.10, 8.74]), and highlighting the expiry date on the kit packaging (M = 8.59, 95% CI [8.29, 8.89]). There were lower levels of support for modifications that reduced the size of the packaging the kit is sent in (M = 6.47, 95% CI [6.09, 6.85]), removed branding from kit packaging (M = 5.98, 95% CI [5.57, 6.39]), and removed the information booklet that comes with the screening kit (M = 5.25, 95% CI [4.78, 5.72]). CONCLUSION These findings highlight multiple ways in which bowel cancer screening kits can be changed to increase usability for invitees of national bowel cancer screening programs. Findings have implications for all screening programs that use immunochemical-based bowel cancer screening kits.

Abstract
PURPOSE Colorectal cancer (CRC) survivors experience treatment-effects such as symptoms and functional impairments. There is limited evidence about how these are managed and what services or supports are available in the community. We aimed to identify current practice and available supports for managing consequences of treatment from clinician and CRC survivor perspectives. METHODS This qualitative study, informed by an interpretivist constructionist paradigm, included semi-structured interviews. Clinicians with experience of treating CRC patients and adult CRC survivors were recruited across Australia. Interviews explored experiences about problems experienced after CRC treatment and how these were managed. Data collection and analysis, using thematic analysis, was iterative whereby emergent themes during analysis were incorporated into subsequent interviews. RESULTS We interviewed 16 clinicians and 18 survivors. Survivors experienced a range of consequences of treatment amendable to support including allied health, information, and self-management. Barriers to support access included clinicians' worry about patient out-of-pocket expenses, long waitlists, lack of awareness about existing supports, and perception no therapeutic options were available. Healthcare professionals with expertise in CRC were often difficult to identify outside of cancer settings. Survivorship care could be improved with individualised timely information and identification of pathways to access healthcare providers with expertise in managing consequences of CRC treatment within primary care. CONCLUSIONS To improve CRC survivor lives posttreatment, routine assessment of consequences of treatment, individualised care planning involving relevant healthcare professionals, access to supportive care when needed, and improved information provision and engagement of a range of health professionals in follow-up care are needed.

Abstract
Bowel cancer is a multifactorial disease arising from a combination of genetic predisposition and environmental factors. Detection of bowel cancer and its precursor lesions is predominantly performed by either visual inspection of the colonic mucosa during endoscopy or cross-sectional imaging. Most cases are diagnosed when the cancer is already at an advanced stage. These modalities are less reliable for detecting lesions at the earliest stages, when they are typically small or flat. Removal of lesions at the earliest possible stage reduces the risk of cancer death, which is largely due to a reduced risk of subsequent metastasis. In this review, we summarised the origin of bowel cancer and the mechanism of its metastasis. In particular, we reviewed a broad spectrum of literatures covering the biomechanics of bowel cancer and its measurement techniques that are pertinent to the successful development of a bowel cancer diagnostic device. We also reviewed existing bowel cancer diagnostic techniques that are available for clinical use. Finally, we outlined current clinical needs and highlighted the potential roles of medical robotics on early bowel cancer diagnosis.

Abstract
BACKGROUND The published literature presents conflicting results regarding the impact of bariatric surgery on the incidence of colorectal cancer. There are important new studies that have addressed this question with longer follow-up. OBJECTIVE To investigate the effect of bariatric surgery on the risk of developing colorectal cancer in patients with obesity. SETTING Meta-analysis. METHODS PubMed and Scopus were searched for relevant articles. Articles published by November 2021 were retrieved; data were extracted according to the evidence-based PICO (population, intervention, control, outcome) model and analyzed using a random-effects model to estimate the pooled relative risk (RR) and its 95% confidence interval. The heterogeneity of studies was tested and quantified using Cochran's Q. RESULTS The initial search yielded 327 articles. After evaluation, 13 studies were analyzed. The thorough evaluation resulted in 13 articles, which were analyzed. A total number of 3,233,044 patients were included in the meta-analysis. The mean time of follow-up was 9.5 ± 7.9 years. The pooled estimate of the adjusted RR was .63 (95% confidence interval, .50-.79). Heterogeneity χ2 was 107.96 (df = 12; P < .001; I2 = 89%). CONCLUSION Patients who underwent bariatric surgery had a 37% reduction in the risk of developing colorectal cancer compared with patients with obesity who had no surgery.

Abstract
BACKGROUND With a high mortality of 12.6% of all cancer cases, colorectal cancer (CRC) accounts for substantial burden of disease in Europe. In the past decade, more and more countries have introduced organized colorectal cancer screening programs, making systematic screening available to entire segments of a population, typically based on routine stool tests and/or colonoscopy. While the effectiveness of organized screening in reducing CRC incidence and mortality has been confirmed, studies continuously report persistent program implementation challenges. This systematic review will synthesize the literature on organized CRC screening programs. Its aim is to understand what is currently known about the barriers and facilitators that influence the implementation of these programs and about the implementation strategies used to navigate these determinants. METHODS A systematic review of primary studies of any research design will be conducted. CENTRAL, CINAHL, EMBASE, International Clinical Trials Registry Platform, MEDLINE, PsycINFO, and Scopus will be searched. Websites of (non-)government health care organizations and websites of organizations affiliated with authors of included studies will be screened for unpublished evaluation reports. Existing organized CRC screening programs will be contacted with a request to share program-specific grey literature. Two researchers will independently screen each publication in two rounds for eligibility. Included studies will focus on adult populations involved in the implementation of organized CRC screening programs and contain information about implementation determinants/ strategies. Publications will be assessed for their risk of bias. Data extraction will include study aim, design, location, setting, sample, methods, and measures; program characteristics; implementation stage, framework, determinants, strategies, and outcomes; and service and other outcome information. Findings will be synthesized narratively using the three stages of thematic synthesis. DISCUSSION With its sole focus on the implementation of organized CRC screening programs, this review will help to fill a central knowledge gap in the literature on colorectal cancer screening. Its findings can inform the decision-making in policy and practice needed to prioritize resources for establishing new and maintaining existing programs in the future.

Abstract
PURPOSE Qualitative research examining healthcare experiences and needs of people with advanced (metastatic or recurrent) colorectal cancer CRC-A is limited. This study aimed to fill this gap in CRC-A survivors treated with surgical or palliative chemotherapy, through a qualitative study. METHOD Australian adults treated for CRC-A were recruited 0.5-2 years post-surgery or post-diagnosis of CRC-A (for palliative chemotherapy groups). Semi-structured telephone interviews, analysed via framework analysis, explored healthcare experiences. Demographic, clinical, and quality of life data characterised the sample and informed framework analyses. Data was compared against the Institute of Medicine's framework for quality healthcare. RESULTS Interviews from 38 participants (22 female) of median age 59 years (range 27-84) revealed six overarching themes relating to the safety, effectiveness, timeliness, patient-centredness, efficiency, and equity of CRC-A care: 1) Early experiences influence later perceptions; 2) Trusting the system, trusting the professionals; 3) The benefits of multidisciplinary care co-ordination; 4) Feeling lost in follow-up; 5) Whose role is it anyway? Gaps in responsibility for survivorship care; and 6) Useful or useless? Perceptions of psychosocial support. CONCLUSIONS Healthcare systems for CRC-A can be improved through delivery of repeated information, upskilling general practitioners and/or implementing written survivorship care plans or survivorship clinics, to ensure quality healthcare.

Abstract
Depending on the patient's constitution, the biological conditions of the primary tumor, the metastases and the liver function and perfusion, a variety of therapeutic options are available. The basis of metastatic surgery of the liver is partial liver resection. Multimodal therapies with local and systemic approaches are used in functionally or oncologically borderline situations. They are intended to improve long-term success and allow curative treatment in more patients. In recent years, for isolated lesions that cannot be removed by partial liver resection, an R0 situation is achieved in selected patients by liver transplantation with good long-term success. The large number of treatment options and the increasing individualization of therapy require treatment planning in the interdisciplinary tumor board. Also, in view of promising studies, for example, in the field of liver transplantation as well as regional therapy methods, the range of treatment options has not yet been exhausted.

The SMARTscreen Trial: a randomised controlled trial investigating the efficacy of a GP-endorsed narrative SMS to increase participation in the Australian National Bowel Cancer Screening Program. Trials 2022; 23:31. [PMID: 35022080 PMCID: PMC8753594 DOI: 10.1186/s13063-021-05877-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Accepted: 11/24/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Increasing participation in the Australian National Bowel Cancer Screening Program (NBCSP) is the most efficient and cost-effective way of reducing mortality associated with colorectal cancer by detecting and treating early-stage disease. Currently, only 44% of Australians aged 50-74 years complete the NBCSP. This efficacy trial aims to test whether this SMS intervention is an effective method for increasing participation in the NBCSP. Furthermore, a process evaluation will explore the barriers and facilitators to sending the SMS from general practice. METHODS We will recruit 20 general practices in the western region of Victoria, Australia to participate in a cluster randomised controlled trial. General practices will be randomly allocated with a 1:1 ratio to either a control or intervention group. Established general practice software will be used to identify patients aged 50 to 60 years old who are due to receive a NBCSP kit in the next month. The SMS intervention includes GP endorsement and links to narrative messages about the benefits of and instructions on how to complete the NBCSP kit. It will be sent from intervention general practices to eligible patients prior to receiving the NBCSP kit. We require 1400 eligible patients to provide 80% power with a two-sided 5% significance level to detect a 10% increase in CRC screening participation in the intervention group compared to the control group. Our primary outcome is the difference in the proportion of eligible patients who completed a faecal occult blood test (FOBT) between the intervention and control group for up to 12 months after the SMS was sent, as recorded in their electronic medical record (EMR). A process evaluation using interview data collected from general practice staff (GP, practice managers, nurses) and patients will explore the feasibility and acceptability of sending and receiving a SMS to prompt completing a NBCSP kit. DISCUSSION This efficacy trial will provide initial trial evidence of the utility of an SMS narrative intervention to increase participation in the NBCSP. The results will inform decisions about the need for and design of a larger, multi-state trial of this SMS intervention to determine its cost-effectiveness and future implementation.

Work: saviour or struggle? A qualitative study examining employment and finances in colorectal cancer survivors living with advanced cancer. Support Care Cancer 2022; 30:9057-9069. [PMID: 35972645 PMCID: PMC9378257 DOI: 10.1007/s00520-022-07307-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Accepted: 07/26/2022] [Indexed: 01/05/2023]
Abstract
PURPOSE Continuing employment or returning to work (RTW) as a cancer survivor can be meaningful and financially necessary, yet challenging. However, there is a lack of qualitative research on RTW experiences and financial wellbeing of people with advanced colorectal cancer (CRC-A). This study aimed to fill this gap. METHODS Adults treated for CRC-A were recruited 0.5-2 years post-surgery (or post-diagnosis of CRC-A for palliative chemotherapy participants). Semi-structured telephone interviews, exploring RTW and finances, were subjected to framework analysis. Demographic, clinical, and quality of life data (FACT-C, Distress Thermometer, COST measure) were collected to characterise the sample and inform the framework analysis. RESULTS Analysis of 38 interviews revealed five overarching themes: work as a struggle, work as my identity, work as my saviour, work as a financial necessity, and employer and colleague response. Many survivors with CRC-A desired to, and had the capacity to, continue work or RTW, yet faced unique challenges from compounded stigma of both cancer and toileting issues. Inability to RTW negatively impacted financial and psychosocial wellbeing. Workplace support was an important facilitator of RTW. CONCLUSION For survivors with CRC-A, continuing or RTW is fraught with challenges, including physical functioning challenges, financial anxiety, and unsupportive workplace environments. Survivors require psychosocial, financial, and employer support to manage these difficulties. This paper recommends a multiprong approach, including education programmes (facilitated through workers' union groups, human resource institutions, and/or large consumer CRC groups) and policies, to support workers and for employers to understand the unique challenges of employees with CRC-A.

Abstract
A 60-year-old man with a background of resected clear cell renal cancer and resected colorectal adenocarcinoma presented with a pulmonary mass lesion in the left upper lobe which was avid on 18-F FDG PET/CT. Needle biopsy confirmed metastatic renal cell cancer, which was surgically excised with wedge resection. Follow-up imaging 6 months later demonstrated a second slowly enlarging subcentimeter nodule in the contralateral lung with increasing FDG avidity, suspicious of further small volume oligometastatic disease. Following surgical resection of the second pulmonary lesion, histopathological examination demonstrated nodular pulmonary amyloidosis and no evidence of malignancy.

Strategies for the treatment of colorectal cancer caused by gut microbiota. Life Sci 2021; 290:120202. [PMID: 34896161 DOI: 10.1016/j.lfs.2021.120202] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2021] [Revised: 11/19/2021] [Accepted: 11/29/2021] [Indexed: 02/07/2023]
Abstract
Colorectal cancer (CRC), also named as colon and rectal or bowel cancer, is one of the leading neoplasia diagnosed in the world. Genetic sequencing studies of microorganisms from the intestinal microbiota of patients with CRC revealed that changes in its composition occur with the development of the disease, which can play a fundamental role in its development, being mediated by the production of metabolites and toxins that damage enterocytes. Some microorganisms are frequently reported in the literature as the main agents of this process, such as the bacteria Fusobacterium nucleatum, Escherichia coli and Bacteroides fragilis. Thus, understanding the mechanisms and function of each microorganism in CRC is essential for the development of treatment tools that focus on the gut microbiota. This review verifies current research aimed at evaluating the microorganisms present in the microbiota that can influence the development of CRC, as well as possible forms of treatment that can prevent the initiation and/or spread of this disease. Due to the incidence of CRC, alternatives have been launched considering factors beyond those already known in the disease development, such as diet, fecal microbiota transplantation, use of probiotics and antibiotics, which have been widely studied for this purpose. However, despite being promising, the studies that focus on the development of new therapeutic approaches targeting the microorganisms that cause CRC still need to be improved and better developed, involving new techniques to elucidate the effectiveness and safety of these new methods.

Abstract
OBJECTIVES To evaluate the effect of general practitioner endorsement accompanying the screening kit rather than with the invitation letter on participation in the NHS Bowel Cancer Screening Programme and on the socioeconomic gradient in participation in the Programme. METHODS The NHS Bowel Cancer Screening Programme in England is delivered via five regional hubs. In early 2016, we carried out a cluster-randomised trial, with hub-day of invitation as the randomisation unit. We randomised 150 hub-days of invitation to the intervention group, GP endorsement on the letter accompanying the guaiac faecal occult blood testing kit (75 hub-days, 197,366 individuals) or control, usual letter (75 hub-days, 197,476 individuals). The endpoint was participation, defined as return of a valid kit within 18 weeks of initial invitation. Because of the cluster randomisation, data were analysed by a hierarchical logistic regression, allowing a random effect for date of invitation. Socioeconomic status was represented by the index of multiple deprivation. RESULTS Participation was 59.4% in the intervention group and 58.7% in the control group, a significant difference (p = 0.04). There was no heterogeneity of the effect of intervention by index of multiple deprivation. We found that there was some confounding between date and screening episode order (first or subsequent screen). This in turn may have induced confounding with age and slightly diluted the result. CONCLUSIONS General practitioner endorsement induces a modest increase in participation in bowel cancer screening, but does not affect the socioeconomic gradient. When considering cluster randomisation as a research method, careful scrutiny of potential confounding is indicated in advance if possible and in analysis otherwise.

Abstract
BACKGROUND Low- and middle-income countries (LMICs) experienced increasing rates of colorectal cancer (CRC) incidence in the last decade and lower 5-year survival rates compared to high-income countries (HICs) where the implementation of screening and treatment services have advanced. This review scoped and mapped the literature regarding the content, implementation and uptake of CRC screening interventions as well as opportunities and challenges for the implementation of CRC screening interventions in LMICs. METHODS We systematically followed a five-step scoping review framework to identify and review relevant literature about CRC screening in LMICs, written in the English language before February 2020. We searched Medline, Embase, Web of Science and Google Scholar for studies targeting the general, asymptomatic, at-risk adult population. The TIDieR tool and an implementation checklist were used to extract data from empirical studies; and we extracted data-informed insights from policy reviews and commentaries. RESULTS CRC screening interventions (n = 24 studies) were implemented in nine middle-income countries. Population-based screening programmes (n = 11) as well as small-scale screening interventions (n = 13) utilised various recruitment strategies. Interventions that recruited participants face-to-face (alone or in combination with other recruitment strategies) (10/15), opportunistic clinic-based screening interventions (5/6) and educational interventions combined with screening (3/4), seemed to be the strategies that consistently achieved an uptake of > 65% in LMICs. FOBT/FIT and colonoscopy uptake ranged between 14 and 100%. The most commonly reported implementation indicator was 'uptake/reach'. There was an absence of detail regarding implementation indicators and there is a need to improve reporting practice in order to disseminate learning about how to implement programmes. CONCLUSION Opportunities and challenges for the implementation of CRC screening programmes were related to the reporting of CRC cases and screening, cost-effective screening methods, knowledge about CRC and screening, staff resources and training, infrastructure of the health care system, financial resources, public health campaigns, policy commitment from governments, patient navigation, planning of screening programmes and quality assurance.

Abstract
BACKGROUND Many non-COVID-19 trials were disrupted in 2020 and either struggled to recruit participants or stopped recruiting altogether. In December 2019, just before the pandemic, we were awarded a grant to conduct a randomised controlled trial, the Should I Take Aspirin? (SITA) trial, in Victoria, the Australian state most heavily affected by COVID-19 during 2020. MAIN BODY We originally modelled the SITA trial recruitment method on previous trials where participants were approached and recruited in general practice waiting rooms. COVID-19 changed the way general practices worked, with a significant increase in telehealth consultations and restrictions on in person waiting room attendance. This prompted us to adapt our recruitment methods to this new environment to reduce potential risk to participants and staff, whilst minimising any recruitment bias. We designed a novel teletrial model, which involved calling participants prior to their general practitioner appointments to check their eligibility. We delivered the trial both virtually and face-to-face with similar overall recruitment rates to our previous studies. CONCLUSION We developed an effective teletrial model which allowed us to complete recruitment at a high rate. The teletrial model is now being used in our other primary care trials as we continue to face the impacts of the COVID-19 pandemic.

Faecal immunochemical testing in bowel cancer screening: Estimating outcomes for different diagnostic policies. J Med Screen 2021; 28:277-285.

Abstract
OBJECTIVES The National Health Service Bowel Cancer Screening Programme (NHS BCSP) in England has replaced guaiac faecal occult blood testing by faecal immunochemical testing (FIT). There is interest in fully exploiting FIT measures to improve bowel cancer (CRC) screening strategies. In this paper, we estimate the relationship of the quantitative haemoglobin concentration provided by FIT in faecal samples with underlying pathology. From this we estimate thresholds required for given levels of sensitivity to CRC and high-risk adenomas (HRA). METHODS Data were collected from a pilot study of FIT in England in 2014, in which 27,238 participants completed a FIT. Those with a faecal haemoglobin concentration (f-Hb) of at least 20 µg/g were referred for further investigation, usually colonoscopy. Truncated regression models were used to explore the relationship between bowel pathology and FIT results. Regression results were applied to estimate sensitivity to different abnormalities for a number of thresholds. RESULTS Participants with CRC and HRA had significantly higher f-Hb, and this remained unchanged after adjusting for age and sex. While a threshold of 20 μg/g was estimated to capture 82.2% of CRC and 64.0% of HRA, this would refer 7.8% of participants for colonoscopy. The current programme threshold used in England of 120 μg/g was estimated to identify 47.8% of CRC and 25.0% of HRA. CONCLUSIONS Under the current diagnostic policy of dichotomising FIT results, a very low threshold would be required to achieve high sensitivity to CRC and HRA, which would place further strain on colonoscopy resources. The NHS BCSP in England might benefit from a diagnostic policy that makes greater use of the quantitative nature of FIT.

An RCT of a decision aid to support informed choices about taking aspirin to prevent colorectal cancer and other chronic diseases: a study protocol for the SITA (Should I Take Aspirin?) trial. Trials 2021; 22:452.

Abstract
Background Australian guidelines recommend that all people aged 50–70 years old actively consider taking daily low-dose aspirin (100–300 mg per day) for 2.5 to 5 years to reduce their risk of colorectal cancer (CRC). Despite the change of national CRC prevention guidelines, there has been no active implementation of the guidelines into clinical practice. We aim to test the efficacy of a health consultation and decision aid, using a novel expected frequency tree (EFT) to present the benefits and harms of low dose aspirin prior to a general practice consultation with patients aged 50–70 years, on informed decision-making and uptake of aspirin. Methods Approximately five to seven general practices in Victoria, Australia, will be recruited to participate. Patients 50–70 years old, attending an appointment with their general practitioner (GP) for any reason, will be invited to participate in the trial. Two hundred fifty-eight eligible participants will be randomly allocated 1:1 to intervention or active control arms using a computer-generated allocation sequence stratified by general practice, sex, and mode of trial delivery (face-to-face or teletrial). There are two co-primary outcomes: informed decision-making at 1-month post randomisation, measured by the Multi-dimensional Measure of Informed Choice (MMIC), and self-reported daily use of aspirin at 6 months. Secondary outcomes include decisional conflict at 1-month and other behavioural changes to reduce CRC risk at both time points. Discussion This trial will test the efficacy of novel methods for implementing national guidelines to support informed decision-making about taking aspirin in 50–70-year-olds to reduce the risk of CRC and other chronic diseases.

Abstract
Quantitative faecal immunochemical tests for haemoglobin (FIT) are being used increasingly around the world in colorectal cancer screening programmes, and in patients presenting with lower bowel symptoms to determine who should proceed to further bowel visualisation investigations, usually colonoscopy. The clinical utility of FIT is well reported. There are a number of analytical challenges including pre-analytical variation, difficulty setting up external quality assessment schemes, access to third party internal quality control material and a lack of standardisation or harmonisation of FIT methods. Here we report the work of the International Federation of Clinical Chemistry FIT Working Group. We provide an overview of the main pre-analytical variables; discuss different approaches to external quality assurance of FIT; propose a solution to third party internal quality assurance materials and summarise the challenges of standardisation and harmonisation of FIT.

Abstract
BACKGROUND Colorectal cancer (CRC) is prevalent in the developed world. Favourable survival rates highlight the need to better understand CRC survivors' experiences of long-term impacts of treatment, which can in turn inform decision making. This systematic review aimed to identify and synthesise CRC survivors' experiences of long-term impacts on health-related quality of life. METHODS We searched Medline, Embase and PsychINFO from inception to January 2019. Qualitative studies describing CRC survivors' experiences at least 1-year post-treatment were included. Study eligibility, quality assessment (COREQ guidelines), and data synthesis was performed independently by two reviewers and discussed with the study team. RESULTS Of 1363 papers retrieved, 20 reporting 15 studies met eligibility. Thematic synthesis produced 12 themes: symptoms, physical, social, psychological and sexual functioning, impact on relationships, informal care needs provided by family/friend, supportive care needs provided by healthcare professional, health care experiences, health behaviour, financial toxicity and occupational experiences. Stoma problems (e.g. leakage, skin irritation) were common in ostomates. Survivors with no/reversed stoma experienced unexpected, long-term altered and unpredictable bowel functioning. Survivors often regulated timing, amount and foods consumed to manage bowel functioning. Less common symptoms included fatigue, impaired sleep and anal pain. Stoma problems and altered bowel functioning impaired survivors' physical, social, sexual and psychological functioning. Cognitive functioning and heredity issues were not reported in any paper. CONCLUSION CRC survivors experience ongoing symptoms and functioning impairments more than 1-year post-treatment completion. Many survivors find their own ways to manage symptoms rather than seek professional help. Follow-up care for CRC survivors should integrate screening for long-term effects and provide targeted supportive care.

Abstract
Background Colorectal cancer (CRC) cases are detected late in Malaysia similar to most Asian countries. The Be Cancer Alert Campaign (BCAC) was a culturally adapted mass media campaign designed to improve CRC awareness and reduce late detection in Malaysia. The evaluation of the BCAC-CRC aimed to assess campaign reach, campaign impact and health service use. Methods Participants aged ≥40 years (n = 730) from randomly selected households in Selangor State Malaysia, completed interview-based assessments. Campaign reach was assessed in terms of responses to an adapted questionnaire that was used in evaluations in other countries. The impact of the campaign was assessed in terms of awareness, confidence to detect symptoms and self-efficacy to discuss symptoms with a doctor as captured by the Cancer Awareness Measure (CAM). CAM was administered before-and-after campaign implementation and responses by BCAC recognisers (i.e. participants who recognised one or more of the BCAC television, radio or print advertisements when prompted) and non-recognisers (i.e. participants who did not recognise any of the BCAC advertisements) were compared analytically. Logistic regression analysed comparative differences in cancer awareness by socio-demographic characteristics and recognition of the BCAC materials. Results Over 65% of participants (n = 484) recognised the BCAC-CRC. Campaign-recognisers were significantly more likely to be aware of each CRC symptom at follow-up and were more confident about noticing symptoms (46.9% vs 34.9%, p = 0.018) compared to non-recognisers. There was no difference between groups in terms of self-efficacy to see a doctor about symptoms. Improved symptoms awareness at follow-up was lower for Indians compared to Malays (adjusted odds ratio (OR) 0.53, 95% Confidence Interval (CI): 0.34, 0.83, p = 0.005). Health service use data did not indicate an increase in screening activity during or immediately after the campaign months. Conclusion Overall, the findings of the evaluation indicated that the culturally adapted, evidence-based mass media intervention improved CRC symptom awareness among the Malaysian population; and that impact is more likely when a campaign operates a differentiated approach that matches modes of communication to the ethnic and social diversity in a population.

Abstract
Objectives Type 2 diabetes has been identified as a risk factor for colorectal cancer, but little is known about whether it influences participation in colorectal cancer screening programmes. This study tested the extent to which Type 2 diabetes is negatively associated with colorectal cancer screening uptake. Methods We analysed individual data of screening eligible men and women aged 60–75 without cancer diagnosis from wave 6 of the English Longitudinal Study of Ageing (collected 2012–2013), to investigate whether Type 2 Diabetes influences colorectal cancer screening behaviour independently of demographic characteristics, body mass index, socio-economic status and other chronic diseases. Results Individuals who reported to have Type 2 diabetes or had glycated haemoglobin (HbA1c) levels of 48 mmol/mol or higher were less likely to have ever completed a screening test (faecal occult blood test; 62.8% vs. 75.8%, p < 0.01) or to be up-to-date with their biennial screening invitation (60.2% vs. 72.0%, p < 0.05). The negative associations of Type 2 diabetes on colorectal cancer screening were found both in unadjusted and adjusted regression models. Conclusions Future qualitative and quantitative research should identify reasons for this discrepancy, to inform interventions to increase screening uptake in this high-risk population.

Abstract
INTRODUCTION the NHS Long Term Plan has called for a reduction in the number of outpatient appointments to reduce pressure on hospital services and increase ease of access for patients. This article presents a service evaluation of an innovative, nurse-led telephone follow-up service for a group of elective bowel cancer patients following surgery. METHODS the records of patients who underwent surgery over a 2-year period were accessed to determine the number of telephone follow-ups and other investigations. This was used to model the potential cost saving for commissioners against traditional clinic follow-up. Patient satisfaction was assessed by the European Organisation for Research and Treatment of Cancer questionnaire on Outpatient Satisfaction in 30 patients. RESULTS feedback on the service was overwhelmingly positive, with patients praising the care received from the specialist nurses, but also commenting on increased continuity of care, ease of access and convenience. The service also potentially creates significant savings for commissioners as the agreed tariff for nurse telephone follow-up is significantly less than the outpatient tariff. DISCUSSION this innovative follow-up system is well liked by patients and should provide savings for commissioners. The hospital also benefits from an increase in capacity to see new or more unwell patients, and a reduction in carbon emissions. Such a service, however, is dependent on people, and although it has functioned effectively in this department for approximately 20 years, it would only be generalisable to other units if staff had appropriate expertise.

[PMID: 31855618 DOI: 10.1016/j.puhe.2019.10.024] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2019] [Revised: 10/18/2019] [Accepted: 10/30/2019] [Indexed: 01/21/2023]
Abstract
OBJECTIVES Bowel cancer screening home-testing kits are offered every two years to individuals aged 60-74 years in the United Kingdom (UK), with prisoners eligible for screening in the same way as the general population. There are currently major changes planned to the bowel cancer screening programme in England, with the transition to the single-sample faecal immunochemical test (FIT) and the planned lowering of the age limit from 60 to 50 years. In this project, we aimed to explore processes and beliefs around bowel cancer screening in an English prison. STUDY DESIGN This is a qualitative study. METHODS Semistructured qualitative interviews were conducted with eight prisoners and four staff members in a male prison in North West England. Data were analysed via thematic analysis. RESULTS Promoting and impeding factors to screening were identified. There was high willingness amongst prisoners to be screened for bowel cancer, with screening seen as important and having benefits for the individual and healthcare system. However, there was often low awareness of screening and there were psychological challenges associated with screening. Prison healthcare staff were widely respected and were a motivator to accept screening, with prisoners viewing prison as a good opportunity to access health care. Despite this, prison life was characterised by competing priorities, with security taking precedence, and screening sometimes a low priority for staff and prisoners. There were also considerable logistical challenges to delivering bowel cancer screening in a prison, and the system was not comparable with that in the community. Providing good-quality understandable information, though challenging, was key. CONCLUSIONS This is the first project to explore entering the bowel cancer screening programme in UK prisons, and promoting and impeding factors to the take-up of screening have been identified. This information could be practically used by local commissioners and policymakers to aid the design of staff and prisoner interventions to maximise uptake of bowel cancer screening in prisons. As the planned changes to bowel cancer screening in England are likely to increase the number of eligible prisoners, this work could also be used to inform any service reconfiguration required to accommodate these changes.

Abstract
INTRODUCTION the NHS Long Term Plan has called for a reduction in the number of outpatient appointments to reduce pressure on hospital services and increase ease of access for patients. This article presents a service evaluation of an innovative, nurse-led telephone follow-up service for a group of elective bowel cancer patients following surgery. METHODS the records of patients who underwent surgery over a 2-year period were accessed to determine the number of telephone follow-ups and other investigations. This was used to model the potential cost saving for commissioners against traditional clinic follow-up. Patient satisfaction was assessed by the European Organisation for Research and Treatment of Cancer questionnaire on Outpatient Satisfaction in 30 patients. RESULTS feedback on the service was overwhelmingly positive, with patients praising the care received from the specialist nurses, but also commenting on increased continuity of care, ease of access and convenience. The service also potentially creates significant savings for commissioners as the agreed tariff for nurse telephone follow-up is significantly less than the outpatient tariff. DISCUSSION this innovative follow-up system is well liked by patients and should provide savings for commissioners. The hospital also benefits from an increase in capacity to see new or more unwell patients, and a reduction in carbon emissions. Such a service, however, is dependent on people, and although it has functioned effectively in this department for approximately 20 years, it would only be generalisable to other units if staff had appropriate expertise.

Health educational background as a predictor of non-participation in national colorectal cancer screening: A cross-sectional population study among 886,088 invited Danes. Prev Med 2019; 125:69-76. [PMID: 31150740 DOI: 10.1016/j.ypmed.2019.05.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2018] [Revised: 05/24/2019] [Accepted: 05/27/2019] [Indexed: 11/22/2022]
Abstract
Health information knowledge may affect attitude toward colorectal cancer screening, but the participation of health educated citizens are unknown. Therefore, we investigated non-participation in a sample of 886,088 invited participants, based on educational length, type, and level. Logistic regression analyses were conducted to estimate the odds of non-participation in Danish men and women based on educational type and length. Models were adjusted for age, income, marital status and immigration status. Information was derived from National registers. Men with long educational length level had increased odds of non-participation if their education was within the field of medicine/medical science (OR 1.87) or belonged to other long health educations, but not in nursing and health care, compared to other long educations after full model adjustment. Women with long educational length level had increased odds of non-participation if they were educated in the field of medicine/medical science (OR 1.47), whereas they had decreased odds in the fields of nursing and health care and other long health educations, compared to other long educations after full model adjustment. Men within short educational length level did not have different odds of nonparticipation, after full model adjustments, whereas women within short health educations were at increased odds in the youngest age group and at decreased odds in the eldest age group. Having an education in the field of medicine/medical science is associated with non-participation in colorectal cancer screening in Denmark 2014-2015. Opposite, an educational background in nursing and health care increased participation in women, but not in men.

Patient perspectives on colorectal cancer screening and the role of general practice. BMC FAMILY PRACTICE 2019; 20:109. [PMID: 31352897 PMCID: PMC6661764 DOI: 10.1186/s12875-019-0997-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 01/22/2019] [Accepted: 07/16/2019] [Indexed: 11/13/2022]
Abstract
Background Colorectal cancer (CRC) is the second most frequent cause of cancer death in Australia. Early detection can reduce incidence and mortality. General practice-based initiatives have been proposed to improve CRC screening rates but to date have had modest impact. As there is limited research into the patient experience of CRC screening decision making, this study explored patient perspectives on CRC screening and the potential role for general practice. Methods Ten participants, aged between 50 and 74, from a general practice in South Australia were recruited by practice staff. Semi-structured interviews were conducted. Concurrent data collection and analysis were performed, guided by interpretative phenomenological analysis. Results Two key themes were evident: attitudes toward screening and potential roles for general practice. Participants structured the experience of screening in terms of being proactive, ambivalent or avoidant. Roles for general practice centred on tasks as educators, trusted advisors, monitors and screeners. Mixed views on whether general practice involvement was necessary prompted consideration of additional sources of health information and motivation around screening. Conclusions Exploration of the patient experience provides insight into how participants make sense of screening and perceived roles for general practice (or other agents) in screening. There is satisfaction with current Government-driven processes but perceived value in general practice playing a complementary part in increasing screening rates. A multifaceted strategy, accounting for attitudes, is required to improve screening and population health outcomes.

A physical activity intervention to improve the quality of life of patients with a stoma: a feasibility study protocol. Pilot Feasibility Stud 2019; 5:78. [PMID: 31236285 PMCID: PMC6580610 DOI: 10.1186/s40814-019-0461-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2019] [Accepted: 06/04/2019] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND Physical activity (PA) is positively associated with quality of life. People with a stoma are less likely to engage in PA than those without a stoma. METHODS In this feasibility intervention study, we will perform the following: (1) Develop a PA intervention for people with a stoma. An Expert Working Group of behavioural scientists, exercise scientists, clinicians and a Patient Advisory Group of people with a bowel stoma will meet with the research team to inform the development of a PA intervention for people with a stoma. A manual of the intervention will be the main output. (2) Explore PA instructors' experiences of delivering the PA intervention. PA instructors will record on paper the number of PA consultations with each patient and a researcher will interview the PA instructors about their experiences of delivering the intervention. (3) Assess the level of patient (bowel cancer or inflammatory bowel disease (IBD) patients with a stoma between 6 weeks and 24 months post-surgery) engagement with the PA intervention and their views on intervention acceptability and usefulness. Patients will keep a PA diary to record daily pedometer recorded step count and type and duration of activities. A researcher will interview patients about their experiences of the PA intervention. (4) Assess screening, eligibility, consent, data completion, loss to follow up, and missing data rates, representativeness of participants and potential treatment effects. A researcher will record on paper all study procedure parameters. Quality of life (stoma-quality of life; Functional Assessment of Cancer Therapy, Short IBD questionnaire), fatigue (FACIT fatigue scale) and PA (accelerometer) will be measured pre- and post-intervention in patients. For IBD patients only, blood will be taken to measure systemic inflammation. DISCUSSION We hypothesise that a PA intervention will be an effective means of improving the quality of life of people with a stoma. Before embarking on a full randomised controlled trial to test this hypothesis, a PA intervention needs to be developed and a feasibility study of the proposed PA intervention conducted. TRIAL REGISTRATION ISRCTN58613962, Protocol version: 0.1. 14 September 2017.

Abstract
INTRODUCTION Rectal cancer is a frequently diagnosed tumor worldwide. Various studies have shown the noninferiority or even slight superiority of laparoscopic resection. However, there is no clear recommendation on whether age should influence the choice of surgical approach. MATERIALS AND METHODS This study compared outcomes of laparoscopic and open surgery in rectal cancer patients. Perioperative mortality and 5-year overall, relative, and recurrence-free survival rates were analyzed separately for three age groups. Data originate from 30 regional German cancer registries that cover approximately one quarter of the German population. All primary nonmetastatic rectal adenocarcinoma cases with surgery between 2005 and 2014 were eligible for inclusion. To compare survival rates, Kaplan-Meier analysis, a relative survival model, and multivariable Cox regression were used; a sensitivity analysis assessed bias by exclusion. RESULTS Ten thousand seven hundred fifty-four patients were included in the analysis. The mean laparoscopy rate was 23.0% and increased over time. Analysis of 30-day postoperative mortality rates revealed advantages for laparoscopically treated patients, although the significance level was not reached in any age group. Regarding 5-year overall survival, laparoscopy generally seems to be the superior approach, whereas for recurrence-free survival, an age-dependent gradient in effect size was observed: with a hazard ratio (HR) of 0.703 for laparoscopy, patients under 60 years benefitted more from the minimally invasive approach than older patients (septuagenarians, HR 0.923). CONCLUSION Laparoscopy shows similar results to the open approach in terms of postoperative survival in all age groups. Concerning long-term outcomes, younger patients benefitted most from the minimally invasive approach.

Abstract
Bowel cancer risk is strongly influenced by lifestyle factors including diet and physical activity. Several studies have investigated the effects of adherence to the World Cancer Research Fund (WCRF)/American Institute for Cancer Research (AICR) cancer prevention recommendations on outcomes such as all-cause and cancer-specific mortality, but the relationships with molecular mechanisms that underlie the effects on bowel cancer risk are unknown. This study aimed to investigate the relationships between adherence to the WCRF/AICR cancer prevention recommendations and wingless/integrated (WNT)-pathway-related markers of bowel cancer risk, including the expression of WNT pathway genes and regulatory microRNA (miRNA), secreted frizzled-related protein 1 (SFRP1) methylation and colonic crypt proliferative state in colorectal mucosal biopsies. Dietary and lifestyle data from seventy-five healthy participants recruited as part of the DISC Study were used. A scoring system was devised including seven of the cancer prevention recommendations and smoking status. The effects of total adherence score and scores for individual recommendations on the measured outcomes were assessed using Spearman's rank correlation analysis and unpaired t tests, respectively. Total adherence score correlated negatively with expression of Myc proto-oncogene (c-MYC) (P=0·039) and WNT11 (P=0·025), and high adherers had significantly reduced expression of cyclin D1 (CCND1) (P=0·042), WNT11 (P=0·012) and c-MYC (P=0·048). Expression of axis inhibition protein 2 (AXIN2), glycogen synthase kinase (GSK3β), catenin β1 (CTNNB1) and WNT11 and of the oncogenic miRNA miR-17 and colonic crypt kinetics correlated significantly with scores for individual recommendations, including body fatness, red meat intake, plant food intake and smoking status. The findings from this study provide evidence for positive effects of adherence to the WCRF/AICR cancer prevention recommendations on WNT-pathway-related markers of bowel cancer risk.

Abstract
The purpose of this systematic review was to compare the diagnostic ability of blood markers for colorectal cancer (CRC). A systematic review of the literature for diagnostic blood markers for primary human colorectal cancer over the last 5 years was performed. The primary outcome was to assess the diagnostic ability of these markers in diagnosing colorectal cancer. The secondary outcome was to see whether the marker was compared to other markers. The tertiary outcome was to assess diagnostic ability in early versus late CRC, including stage IV disease. We identified 51 studies (29 prospective, 14 retrospective, and 8 meta-analyses). The markers were divided in broadly four groups: nucleic acids (RNA/DNA/messenger RNA/microRNAs), cytokines, antibodies, and proteins. The most promising circulating markers identified among the nucleid acids were NEAT_v2 non-coding RNA, SDC2 methylated DNA, and SEPT9 methylated DNA. The most promising cytokine to detect CRC was interleukin 8, and the most promising circulating proteins were CA11-19 glycoprotein and DC-SIGN/DC-SIGNR. Sensitivities of these markers for detecting primary colorectal carcinoma ranged from 70 to 98% and specificities from 84 to 98.7%. The best studied blood marker was SEPT9 methylated DNA, which showed great variability with sensitivities ranging from 48.2 to 95.6% and specificities from 80 to 98.9%, making its clinical applicability challenging. If combined with fecal immunochemical test (FIT), the sensitivity improved from 78 to 94% in detecting CRC. Methylated SEPT9, methylated SDC2, and -SIGN/DC-SIGNR protein had better sensitivity and specificity than CEA or CA 19-9. With the exception of SEPT9 which is currently being implemented as a screening test for CRC all other markers lacked reproducibility and standardization and were studied in relatively small population samples.

Abstract
AIM In the UK Bowel Scope Screening Programme (BSSP), patients progress to colonoscopy based on high-risk features on flexible sigmoidoscopy (FS). We aim to assess the practice of colonoscopy conversion and predictors of detection of additional adenomas on colonoscopy. METHOD The Bowel Cancer Screening database was interrogated and collated with endoscopic and histological findings from patients undergoing colonoscopy following FS between August 2013 and August 2016. Multivariate analysis was performed to identify predictors of new adenomas. RESULTS FS was performed on 11 711 patients, with an adenoma detection rate (ADR) of 8.5% and conversion to colonoscopy in 421 (3.6%). The additional ADR at colonoscopy was 35.2%, with one additional malignant diagnosis (0.26%). The adenoma miss rate was 3.6%. On multivariate analysis, a polyp ≥ 10 mm was the only high-risk indication associated with additional ADR at colonoscopy (OR 3.68, 95% CI 1.51-3.65, P < 0.001), in addition to male gender (OR 2.36, 95% CI 1.46-3.83, P < 0.001). Predictors of detection of a new adenoma ≥ 10 mm included: villous adenoma (P = 0.002), polyp ≥ 10 mm (P = 0.007) and male gender (P = 0.039). The presence of any conversion criterion was associated with the detection of any proximal adenoma (P < 0.001) and adenoma ≥ 10 mm (P = 0.031). CONCLUSION Male gender, polyps ≥ 10 mm and villous-preponderant histology at FS were predictors of adenomas < 10 mm and ≥ 10 mm at colonoscopy. Further data are required to assess the role for gender-based stratification of conversion criteria.

Long-term oncologic outcomes after laparoscopic versus open rectal cancer resection: a high-quality population-based analysis in a Southern German district. Surg Endosc 2018; 32:4096-4104. [PMID: 29611044 PMCID: PMC6132875 DOI: 10.1007/s00464-018-6148-6] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2017] [Accepted: 03/21/2018] [Indexed: 12/17/2022]
Abstract
BACKGROUND An increasing number of rectal carcinoma resections in Germany and worldwide are performed laparoscopically. The recently published COLOR II trial demonstrated the oncologic safety of this surgical approach. It remains unclear whether these findings can be transferred to clinical practice. PATIENTS AND METHODS This population-based retrospective cohort study aimed to evaluate 5-year overall, relative, disease-free, and local recurrence-free survival of rectal cancer patients treated by open surgery and laparoscopy. Data from a southern German region of 1.1 million inhabitants were collected by an official clinical cancer registry. All primary non-metastatic rectal adenocarcinoma cases with surgery between 2004 and 2013 were eligible for inclusion. To compare survival rates, Kaplan-Meier analyses, relative survival models, and multivariate Cox regression were applied; a sensitivity analysis assessed bias by exclusion. RESULTS Finally, 1507 patients with a median follow-up time of 7.1 years were included. Of these patients, 28.4% underwent laparoscopic procedures, with an increasing rate over time. Patients with tumors of the upper or middle rectum, younger patients, and patients of specialized colorectal cancer centers were more likely to undergo laparoscopy. After 5 years, 80.4% of laparoscopy patients were still alive, compared to 68.6% in the open group (p < 0.001). Moreover, laparoscopy was associated with superior local recurrence-free survival rates. This advantage was also significant in multivariate analysis (HR 0.70, 95% CI 0.52-0.92). CONCLUSION Laparoscopic rectal cancer surgery can be considered safe in daily clinical practice. This should be confirmed by future studies outside the setting of randomized trials.

Abstract
In the present study, we aimed to assess the level of awareness regarding CRC warning signs and risk factors among undergraduate students. A cross-sectional survey using standardized questionnaire developed by the Cancer Research Center in the UK was carried out in three different public universities in Jordan including Jordan University of Science and Technology, Yarmouk University, and AL al-Bayt University over a 5-month period. Volunteers were asked about their knowledge regarding CRC symptoms, risk factors, and their behaviors regarding seeking medical advice. Findings revealed that response rate was 80.1%. Vast majority of responders were female (70.9%) and 18.2% of them were studying medical-related specialties. Regarding CRC symptoms, 14.3% of responders experienced poor knowledge, 52.9% have fair knowledge, and 32.8% have good knowledge. Abdominal pain was the most recognized warning signs where 70.8% of responders could recall it. In addition, risk factors awareness was lower than warning signs awareness. About 36.1% of responders have poor knowledge, 47.4% had fair knowledge, and 16.5% had good knowledge. Unhealthy diet was the most recognized risk factor where 32.3% of responders could recall it. Moreover, females were more aware regarding CRC symptoms. Similar findings were obtained for participants who were aged 20 years or more and for those who had previous experience of cancer. Students who were studying medical-related specialties were more aware of both CRC symptoms and risk factors than those who studying other specialties. Furthermore, regarding time to seek medical attention we found that 60.6% of volunteers would seek medical advice within 1 week of noticing CRC symptoms and 12% would seek it within 2 weeks. The mean duration for seeking medical advice was found to be 1.9 weeks. University students' awareness level of CRC is poor, and therefore, extended attention should be attempted to enhance the awareness of CRC via continuous education programs, lectures, or campaigns to encourage the early detection CRC.

Long-term oncologic outcomes after laparoscopic vs. open colon cancer resection: a high-quality population-based analysis in a Southern German district. Surg Endosc 2018; 32:4138-4147.

Abstract
Background Over 20 years after the introduction of laparoscopic surgery for colon cancer, many surgeons still prefer the open approach. Whereas randomized controlled trials (RCTs) have proven the oncologic safety of laparoscopy, long-term data depicting daily clinical routine are scarce. Methods This population-based cohort study compares 5-year overall, relative, and recurrence-free survival rates after laparoscopic and open colon carcinoma surgery. Data derive from an independent German cancer registry encompassing all tumor patients within a political district of 1.1 million inhabitants. The final analysis included 2669 patients with major elective resection of primary non-metastatic colonic adenocarcinoma between January 1, 2004 and December 31, 2013. Survival rates were compared using Kaplan–Meier analyses, relative survival models, and multivariate Cox regression. Sensitivity analysis quantified selection bias. Results The proportion of laparoscopic procedures increased from 9.7 to 25.8% in 2011 and dropped again to 15.8% at the end of observation period. Laparoscopy patients were younger, had a lower tumor stage, and were more likely to receive postoperative chemotherapy. Overall, relative, and recurrence-free survival was significantly superior or equivalent in Kaplan–Meier analysis (5-year overall survival rate open vs. laparoscopic: 69.0 vs. 80.2%, p < 0.001). The superiority of laparoscopy mostly remained stable after adjusting for confounders, although significance was only reached in T1-3 patients without lymph node metastases (overall survival: hazard ratio (HR) 0.654; 95% confidence interval (CI) 0.446–0.958; p = 0.029). Conclusion Laparoscopy is a safe and promising alternative to the open approach in daily clinic practice. These favorable outcomes require future confirmation by high-quality studies outside the setting of RTCs.

General practitioners' perceptions of population based bowel screening and their influence on practice: a qualitative study. BMC FAMILY PRACTICE 2017; 18:36.

Abstract
Background Although largely preventable, Australia has one of the highest rates of bowel cancer in the world. General Practitioners (GPs) have an important role to play in prevention and early detection of bowel cancer, however in Australia this is yet to be optimised and participation remains low. This study sought to understand how GPs’ perceptions of bowel screening influence their attitudes to, and promotion of the faecal occult blood test (FOBT), to identify opportunities to enhance their role. Methods Interviews were conducted with 31 GPs from metropolitan and regional New South Wales (NSW), Australia. Discussions canvassed GPs’ perceptions of their role in bowel screening and the national screening program; perceptions of screening tests; practices regarding discussing screening with patients; and views on opportunities to enhance their role. Transcripts were coded using Nvivo and thematically analysed. Results The study revealed GPs’ perceptions of screening did not always align with broader public health definitions of ‘population screening’. While many GPs reportedly understood the purpose of population screening, notions of the role of asymptomatic screening for bowel cancer prevention were more limited. Descriptions of screening centred on two major uses: the use of a screening ‘process’ to identify individual patients at higher risk; and the use of screening ‘tools’, including the FOBT, to aid diagnosis. While the FOBT was perceived as useful for identifying patients requiring follow up, GPs expressed concerns about its reliability. Colonoscopy by comparison, was considered by many as the gold standard for both screening and diagnosis. This perception reflects a conceptualisation of the screening process and associated tools as an individualised method for risk assessment and diagnosis, rather than a public health strategy for prevention of bowel cancer. Conclusion The results show that GPs’ perceptions of screening do not always align with broader public health definitions of ‘population screening’. Furthermore, the way GPs understood screening was shown to impact their clinical practice, influencing their preferences for, and use of ‘screening’ tools such as FOBT. The findings suggest emphasising the preventative opportunity of FOBT screening would be beneficial, as would formally engaging GPs in the promotion of bowel screening.

Improving adherence to colorectal cancer surveillance guidelines: results of a randomised controlled trial. BMC Cancer 2017; 17:106. [PMID: 28166751 PMCID: PMC5294678 DOI: 10.1186/s12885-017-3095-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2016] [Accepted: 01/31/2017] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Colorectal cancer (CRC) survivors are at increased risk of developing the disease again. Surveillance guidelines are aimed at maximising the early detection of recurring or new cancers and pre-cancerous polyps. The frequency and type of surveillance recommended depends on the type of treatment for the initial CRC, the extent of colonoscopic investigation prior to treatment and the results of previous surveillance tests. This paper aimed to test the effect of a paper-based educational intervention to improve adherence to colonoscopy following treatment for colorectal cancer. METHODS People with a diagnosis of colorectal cancer within the last 10 months, aged ≥18 and English speaking were recruited through a population-based cancer registry in Australia. Participants were randomly allocated to either the intervention or control. Participants completed an interview at baseline. Self-reported participation in colonoscopy was obtained at 12 month followup by survey. Those allocated to the control received a generic pamphlet on colorectal cancer treatment; while intervention participants received a letter which provided specific information about guideline recommendations for surveillance colonoscopy. Rates of guideline adherence were compared between groups. The guideline recommendations for the timing of surveillance colonoscopy changed part way through the study. This change occurred after all intervention materials had been sent, but prior to all participants completing the 12 month follow up. Post hoc analyses were conducted to assess adherence to the new guidelines. RESULTS Of the 767 participants, 604 (79%) had had surgery, had stage I - III disease and completed the baseline interview within 12 months of diagnosis (intervention = 305; control = 299). There was no significant difference between those adherent to surveillance colonoscopy guidelines, in the control (67, 27%) and intervention groups (80, 31%) at followup (difference = 4.3% (95%CI:-3.7%, 12%), χ 2(1df) = 1.09, P = 0.296). Overall, 246 (49%) participants were adherent to the new guidelines, compared to 147 (29%) adherent to the old guidelines. CONCLUSIONS Results indicate the paper-based educational intervention is not effective in improving adherence to colorectal cancer surveillance guidelines for colonoscopy.

A systematic review of geographical differences in management and outcomes for colorectal cancer in Australia. BMC Cancer 2017; 17:95. [PMID: 28152983 PMCID: PMC5290650 DOI: 10.1186/s12885-017-3067-1] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2016] [Accepted: 01/18/2017] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND Australia and New Zealand have the highest incidence of colorectal cancer (CRC) in the world, presenting considerable health, economic, and societal burden. Over a third of the Australian population live in regional areas and research has shown they experience a range of health disadvantages that result in a higher disease burden and lower life expectancy. The extent to which geographical disparities exist in CRC management and outcomes has not been systematically explored. The present review aims to identify the nature of geographical disparities in CRC survival, clinical management, and psychosocial outcomes. METHODS The review followed PRISMA guidelines and searches were undertaken using seven databases covering articles between 1 January 1990 and 20 April 2016 in an Australian setting. Inclusion criteria stipulated studies had to be peer-reviewed, in English, reporting data from Australia on CRC patients and relevant to one of fourteen questions examining geographical variations in a) survival outcomes, b) patient and cancer characteristics, c) diagnostic and treatment characteristics and d) psychosocial and quality of life outcomes. RESULTS Thirty-eight quantitative, two qualitative, and three mixed-methods studies met review criteria. Twenty-seven studies were of high quality, sixteen studies were of moderate quality, and no studies were found to be low quality. Individuals with CRC living in regional, rural, and remote areas of Australia showed poorer survival and experienced less optimal clinical management. However, this effect is likely moderated by a range of other factors (e.g., SES, age, gender) and did appear to vary linearly with increasing distance from metropolitan centres. No studies examined differences in use of stoma, or support with stomas, by geographic location. CONCLUSIONS Overall, despite evidence of disparity in CRC survival and clinical management across geographic locations, the evidence was limited and at times inconsistent. Further, access to treatment and services may not be the main driver of disparities, with individual patient characteristics and type of region also playing an important role. A better understanding of factors driving ongoing and significant geographical disparities in cancer related outcomes is required to inform the development of effective interventions to improve the health and welfare of regional Australians.

Impact of non-clinical community-based promotional campaigns on bowel cancer screening engagement: An integrative literature review. PATIENT EDUCATION AND COUNSELING 2016; 99:1549-57. [PMID: 27270183 DOI: 10.1016/j.pec.2016.05.012] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/11/2015] [Revised: 04/25/2016] [Accepted: 05/14/2016] [Indexed: 05/15/2023]
Abstract
OBJECTIVE This paper reviewed the relationship between non-clinical, client-oriented promotional campaigns to raise bowel cancer awareness and screening engagement. METHOD An integrative literature review using predefined search terms was conducted to summarise the accumulated knowledge. Data was analysed by coding and categorising, then synthesized through development of themes. RESULTS Eighteen of 116 studies met inclusion criteria. Promotional campaigns had varying impact on screening uptake for bowel cancer. Mass media was found to moderately increase screening, predominately amongst "worried well". Small media used in conjunction with other promotional activities, thus its effect on screening behaviours was unclear. One-on-one education was less effective and less feasible than group education in increasing intention to screen. Financial support was ineffective in increasing screening rates when compared to other promotional activities. Screening engagement increased because of special events and celebrity endorsement. CONCLUSION Non-clinical promotional campaigns did impact uptake of bowel cancer screening engagement. However, little is evident on the effect of single types of promotion and most research is based on clinician-directed campaigns. PRACTICE IMPLICATIONS Cancer awareness and screening promotions should be implemented at community and clinical level to maximize effectiveness. Such an approach will ensure promotional activities are targeting consumers, thus strengthening screening engagement.

Impact of Primary Tumor Site on Bevacizumab Efficacy in Metastatic Colorectal Cancer. Clin Colorectal Cancer 2016; 15:e9-e15. [PMID: 26968236 DOI: 10.1016/j.clcc.2016.02.007] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2015] [Accepted: 02/03/2016] [Indexed: 12/13/2022]
Abstract
BACKGROUND With an ever-increasing focus on personalized medicine, all factors known to affect treatment response need to be considered when defining optimal therapy for individual patients. While the prognostic impact of primary tumor site on colorectal cancer (CRC) outcomes is established, emerging data suggest potential differences in response to biologic therapies. We studied the impact of tumor site on bevacizumab efficacy in patients with metastatic CRC. PATIENTS AND METHODS We analyzed data of patients in an Australian prospective multicenter metastatic CRC (mCRC) registry who received first-line chemotherapy. Tumor site was defined as right colon, cecum to transverse; left colon, splenic flexure to rectosigmoid; and rectum. Kaplan-Meier and Cox models were used for survival analyses. RESULTS Of 926 patients, 297 had right colon, 354 left colon, and 275 rectum primary disease. Median age was 68.6, 65.9, and 63.3 years, respectively (P = .001). Right colon disease was significantly associated with intraperitoneal spread (P < .0001), while left colon and rectum disease preferentially metastasized to the liver and lungs, respectively (P < .0001 in both settings). A total of 636 patients (68.7%) received bevacizumab. Progression-free survival was superior for bevacizumab-treated patients in all groups but appeared greatest in right colon disease (hazard ratio, 0.46; 95% confidence interval, 0.36-0.60; P ≤ .001). Overall survival was longest in patients with disease of the rectum, followed by left colon and right colon (median, 26.2, 23.6, and 18.2 months, respectively; P = .0004). CONCLUSION Tumor site appears to be prognostic in mCRC, with rectum and right colon disease associated with the best and worst outcomes, respectively. Patients who received bevacizumab in addition to chemotherapy had superior outcomes, with the effect appearing greatest in patients with right colon disease.

Primary Tumor Resection and Overall Survival in Patients With Metastatic Colorectal Cancer Treated With Palliative Intent. Clin Colorectal Cancer 2015; 15:e125-32. [PMID: 26803709 DOI: 10.1016/j.clcc.2015.12.010] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2015] [Revised: 12/11/2015] [Accepted: 12/17/2015] [Indexed: 12/31/2022]
Abstract
BACKGROUND The survival impact of primary tumor resection in patients with metastatic colorectal cancer (mCRC) treated with palliative intent remains uncertain. In the absence of randomized data, the objectives of the present study were to examine the effect of primary tumor resection (PTR) and major prognostic variables on overall survival (OS) of patients with de novo mCRC. PATIENTS AND METHODS Consecutive patients from the Australian 'Treatment of Recurrent and Advanced Colorectal Cancer' registry were examined from June 2009 to March 2015. Univariate and multivariate Cox proportional hazards regression analyses were used to identify associations between multiple patient or clinical variables and OS. Patients with metachronous mCRC were excluded from the analyses. RESULTS A total of 690 patients de novo and 373 metachronous mCRC patients treated with palliative intent were identified. The median follow-up period was 30 months. The median age of de novo patients was 66 years; 57% were male; 77% had an Eastern Cooperative Oncology Group performance status of 0 to 1; and 76% had a colon primary. A total of 216 de novo mCRC patients treated with palliative intent underwent PTR at diagnosis and were more likely to have a colon primary (odds ratio [OR], 15.4), a lower carcinoembryonic antigen level (OR, 2.08), and peritoneal involvement (OR, 2.58; P < .001). On multivariate analysis, PTR at diagnosis in de novo patients was not associated with significantly improved OS (hazard ratio [HR], 0.82; 99% confidence interval [CI], 0.62-1.09; P = .068). PTR at diagnosis did not correlate with outcome in de novo patients with a colon primary (HR, 0.74; 99% CI, 0.54-1.01; P = .014) or a rectal primary (HR, 0.81; 99% CI, 0.27-2.44; P = .621). CONCLUSION For de novo mCRC patients treated with palliative intent, PTR at diagnosis does not significantly improve OS when adjusting for known major prognostic factors. The outcomes of randomized trials examining the survival impact of PTR are awaited.

Is Radical Bowel Cancer Resection Under Local Anaesthesia and Sedation Feasible? Indian J Surg 2015; 77:260-4. [PMID: 26702231 PMCID: PMC4688268 DOI: 10.1007/s12262-015-1281-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2015] [Accepted: 05/11/2015] [Indexed: 10/23/2022] Open
Abstract
Some patients with bowel cancer have significant comorbidities, making them unfit for major surgery under general anaesthesia. However, treatment without surgery offers no possibility of cure, and furthermore, symptom control may be poor. We investigated the possibility of performing these resections under local anaesthesia in patients with a slim body habitus in a cohort of patients rejected for general anaesthesia. Eight patients (4 M, 4 F) aged 77-89 were included in this study. All had significant comorbidities and were deemed unfit for general anaesthesia by the consultant anaesthetist in charge of pre assessing high-risk patients. All patients had undergone a thorough assessment, which included P-POSSUM scoring. The recruited patients underwent a careful and fully informed consenting process, leading to standard cancer resections. These resections occurred between 2005 and 2012, under combined local anaesthesia and sedation. The operations undertaken were four right hemicolectomies (for caecal cancer), two Hartmann's procedures (for sigmoid cancer), one Hartmann's procedure with en bloc small bowel resection (for sigmoid cancer invading small bowel) and one transverse colectomy (for mid transverse colon cancer). Seven patients survived radical surgery without complications, although one died from an unrelated cause 8 months after surgery. One of these surviving patients subsequently underwent CABG and further bowel surgery under GA 2 years later for a metachronous sigmoid cancer. There was one postoperative death due to cardiogenic shock on the third postoperative day. Radical cancer resections under local anaesthesia are feasible in suitably selected high-risk patients with acceptable mortality and comparable medium- to long-term results.

Assessment of family history of colorectal cancer in primary care: perceptions of first degree relatives of people with colorectal cancer. PATIENT EDUCATION AND COUNSELING 2014; 94:427-431. [PMID: 24380670 DOI: 10.1016/j.pec.2013.11.014] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/26/2013] [Revised: 11/06/2013] [Accepted: 11/30/2013] [Indexed: 06/03/2023]
Abstract
OBJECTIVE First degree relatives (FDRs) of someone with colorectal cancer (CRC) are at increased risk of the disease. In this study we examine the factors associated with discussing family history of CRC with a health professional. METHODS People with CRC, recruited through the population-based Victorian Cancer Registry in Australia, were asked to refer FDRs to the study. Eight hundred and nineteen FDRs completed a telephone interview. RESULTS Thirty-six percent of FDRs recalled ever being asked about their family history of bowel cancer by a health professional. Factors associated with having this discussion were being aged 50-60 years, having a university education, being in the potentially high risk category, being very worried about getting bowel cancer and knowing that family history increases risk through discussions with family, friends or their own education. CONCLUSION Despite evidence that doctor endorsement is a key factor in the uptake of CRC screening, our study shows that the majority of FDRs do not recall being asked by a health professional about their family history. PRACTICE IMPLICATIONS There is a need to identify the most appropriate method to improve rates of health professional discussion of family history with relatives of CRC patients in order to improve screening rates.

Trends on gastrointestinal bleeding and mortality: Where are we standing? World J Gastroenterol 2012; 18:1154-8. [PMID: 22468077 PMCID: PMC3309903 DOI: 10.3748/wjg.v18.i11.1154] [Citation(s) in RCA: 51] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2011] [Revised: 08/21/2011] [Accepted: 02/27/2012] [Indexed: 02/06/2023] Open
Abstract
Bleeding from the gastrointestinal tract and its management are associated with significant morbidity and mortality. The predisposing factors that led to the occurrence of these hemorrhagic instances are largely linked to the life style of the affected persons. Designing a new strategy aimed at educating the publics and improving their awareness of the problem could effectively help in eradicating this problem with no associated risks and in bringing the mortality rates down to almost zero.
