Abstract
BACKGROUND Screening adherence is important in reducing colorectal cancer (CRC) incidence and mortality. Disparity in CRC screening adherence was observed in populations of different socioeconomic status (SES), but the direction and strength of the association remained unclear. OBJECTIVE We aimed to systematically review all the observational studies that have analyzed the association between SES and adherence to organized CRC screening based on fecal occult blood tests. METHODS We systematically reviewed the studies in PubMed, Embase, and Web of Science and reference lists of relevant reviews from the inception of the database up until June 7, 2023. Individual SES, neighborhood SES, and small-area SES were included, while any SES aggregated by geographic areas larger than neighbors were excluded. Studies assessing SES with any index or score combining indicators of income, education, deprivation, poverty, occupation, employment, marital status, cohabitation, and others were included. A random effect model meta-analysis was carried out for pooled odds ratios (ORs) and relative risks for adherence related to SES. RESULTS Overall, 10 studies, with a total of 3,542,379 participants and an overall adherence rate of 64.9%, were included. Compared with low SES, high SES was associated with higher adherence (unadjusted OR 1.73, 95% CI 1.42-2.10; adjusted OR 1.53, 95% CI 1.28-1.82). In the subgroup of nonindividual-level SES, the adjusted association was significant (OR 1.57, 95% CI 1.26-1.95). However, the adjusted association was insignificant in the subgroup of individual-level SES (OR 1.46, 95% CI 0.98-2.17). As for subgroups of the year of print, not only was the unadjusted association significantly stronger in the subgroup of early studies (OR 1.97, 95% CI 1.59-2.44) than in the subgroup of late studies (OR 1.43, 95% CI 1.31-1.56), but also the adjusted one was significantly stronger in the early group (OR 1.86, 95% CI 1.43-2.42) than in the late group (OR 1.26, 95% CI 1.14-1.39), which was consistent and robust. Despite being statistically insignificant, the strength of the association seemed lower in studies that did not adjust for race and ethnicity (OR 1.31, 95% CI 1.21-1.43) than the overall estimate (OR 1.53, 95% CI 1.28-1.82). CONCLUSIONS The higher-SES population had higher adherence to fecal occult blood test-based organized CRC screening. Neighborhood SES, or small-area SES, was more competent than individual SES to be used to assess the association between SES and adherence. The disparity in adherence between the high SES and the low SES narrowed along with the development of interventions and the improvement of organized programs. Race and ethnicity were probably important confounding factors for the association.

Abstract
OBJECTIVES Significant disparities exist between different ethnic groups when it comes to participation in colorectal cancer (CRC) screening programmes. A variety of interventions have been proposed to improve participation rates of ethnic minorities for CRC screening. This systematic review aims to appraise the evidence available from published randomised controlled trials (RCTs) and to identify effective interventions aimed at promoting CRC screening amongst underserved ethnic minorities. DESIGN We searched EmBASE, Medline, PsychInfo, Scopus and CINAHL for RCTs that analysed interventions to promote CRC screening in all ethnic minorities. CRC screening was measured as documented or self-reported screening rates. The protocol of this study was registered prospectively on PROSPERO with the registration number CRD42020216384. RESULTS We identified 42 relevant RCT articles, out of 1805 articles highlighted by the initial search. All except one were conducted in the US. The most frequently studied ethnic groups were African-Americans (33%), East Asians (30%), and Hispanics/Latinos (23%). In total, 7/42 (16%) RCTs had multiple arms. Interventions mainly intended to educate (52%), provide patient navigation services (21%), or provide a combination of these interventions (19%). We demonstrate that combination methods are most effective. CONCLUSION Many RCTs, mostly in the US, have trialed interventions aimed to increase CRC screening uptake amongst ethnic minorities to varying success. We conclude that using a combination of methods with patient navigation, education, and cultural tailoring is most effective at increasing CRC screening uptake amongst ethnic minorities. This highlights that multiple factors may hinder CRC screening and finding a one-size-fits-all solution that can be reliably implemented among different cultures and countries may be complex.

Abstract
AIM We look at the effect of introducing the faecal immunochemical test (FIT) in the straight-to-test 2-week pathway for change in bowel habit (CIBH). METHOD The FIT in primary care triages 2-week wait (2WW) colorectal referrals for patients aged 60 years and above for straight-to-test CT colonography (CTC). We compare the impact of the FIT on numbers of 2WW CTCs, in the year before and after FIT, in both colorectal cancer (CRC) detection and cost-effectiveness at both 4 μg Hb/g faeces and 10 μg Hb/g faeces. RESULTS At a threshold of 4 μg Hb/g faeces, the positive predictive value of the FIT for diagnosis of CRC is 5.0% with a negative predictive value of 99.8% and a polyp detection rate of 25.5%. The introduction of the FIT resulted in a reduction in the number of CTCs performed through the CIBH pathway from a mean of 143.9 per month prior to the FIT to 66.8 CTCs per month once the FIT was well established. Given a FIT threshold of 10 μg Hb/g the number of CTCs would be predicted to fall by 70.4% to 42.6 CTCs per month resulting in higher CRC and polyp detection rate, and an estimated annual cost saving of £238 258 in our institution. CONCLUSION The FIT use in primary care improves the yield of 2WW referrals for CIBH alone and reduces the burden and cost of investigations to exclude CRC. Improvements may be possible by increasing the cut-off employed, without adversely affecting the risk of missing a cancer.

Abstract
(1) Background: Fecal occult blood test (FOBT) is the modality of choice in most countries for colorectal cancer (CRC) screening. We aimed to investigate the risk factors for CRC among patients with a positive FOBT in real life. (2) Methods: This was a retrospective study that included patients who tested positive for FOBT. Data regarding the comorbidities and laboratories were collected and compared between CRC and non-CRC groups. (3) Results: Positive FOBT was found among 45,500 (5.36%) subjects and CRC was found in 1502 (3.3%). CRC patients were older, age 62.7 ± 7.15 years compared with 59.33 ± 7.3 years (p < 0.001), and had significantly higher rates of hypertension (48.4% vs. 44.7%, p = 0.002), iron-deficiency anemia (20.6% vs. 16.4, p < 0.001), family history of CRC (7.3% vs. 5.1%, p < 0.001), and previous CRC (6.5% vs. 0.3%, p < 0.001). Lower levels of hemoglobin, iron, and ferritin were found in the CRC group. Age, family history of CRC, and previous CRC were found to be significant risk factors for diagnosis of CRC after positive FOBT with OR of 1.057, 1.4, and 15.9, respectively. (4) Conclusions: Iron-deficiency anemia, family history of CRC, previous colorectal cancer, and low hemoglobin, iron, and ferritin levels should direct physicians to give high priority to colonoscopy scheduling.

Abstract
AIM Colorectal cancer (CRC) screening reduces mortality but variation exists in uptake, with poorer uptake in ethnic minority groups. The aim of this work was to evaluate the relationship between ethnicity and uptake of CRC screening in West London. METHOD Results of CRC screening from the Central London, West London, Hammersmith and Fulham, Hounslow and Ealing Clinical commissioning group collaborative between 2012 and 2017 were retrospectively analysed. These five clinical commissioning groups (CCGs) are located in West London. Compliance with screening according to ethnic group was evaluated compared with White British as the control. RESULTS A total of 155 038 individuals were screened. White British individuals had the highest compliance (52.6%). A maximum difference in compliance of 8.2% was seen between CCGs. The odds of being less likely to participate were significant (p < 0.05) in all ethnic minorities except for Asian Chinese on univariate and multivariate analysis (adjusted OR 1.091, p = 0.88). CONCLUSION This is the largest retrospective study focusing on the role of ethnicity in the uptake of CRC screening in England. Poor uptake of screening in all ethnic minorities in West London, with the exception of Asian Chinese individuals in particular, is a novel finding. A mandate to routinely collect ethnicity data, the use of a single more diverse census and further intervention are needed to understand this disparity and reduce health inequity.

Abstract
Few studies have directly targeted nonparticipants in colorectal cancer screening to identify effective engagement strategies. We undertook a randomized controlled trial that targeted nonparticipants in a previous trial of average-risk subjects which compared participation rates for mailed invitations offering a fecal test, a blood test or a choice of either. Nonparticipants (n = 899) were randomized to be offered a kit containing a fecal immunochemical test (FIT), directions on how to arrange a blood DNA test, or the option of doing either. Screening participation was assessed 12 weeks after the offer. To assess the cognitive and attitudinal variables related to participation and invitee choice, invitees were surveyed after 12 weeks, and associations were investigated using multinomial logistic regression. Participation rates were similar between groups (P = 0.88): 12.0% for FIT (35/292), 13.3% for the blood test (39/293), and 13.4% for choice (39/290). Within the choice group, participation was significantly higher with FIT (9.7%, 28/290) compared with the blood test (3.8%, 11/290, P = 0.005). The only variable significantly associated with participation was socioeconomic status when offered FIT, and age when offered choice but there was none when offered the blood test. Survey respondents indicated that convenience, time-saving, comfort, and familiarity were major influences on participation. There was no clear advantage between a fecal test, blood test, or choice of test although, when given a choice, the fecal test was preferred. Differences in variables associated with participation according to invitation strategy warrant consideration when deciding upon an invitation strategy for screening nonparticipants. PREVENTION RELEVANCE: This trial of screening for those at average risk for colorectal cancer targeted past fecal-test nonparticipants and compared participation rates for mailed invitations offering a fecal test, blood test, or choice of either. Although there was no clear advantage between strategies, factors associated with participation differed between each strategy.

Abstract
BACKGROUND Lung cancer screening (LCS) with low-dose CT (LDCT) was implemented in the United States following the National Lung Screening Trial (NLST). The real-world benefits of implementing LCS are yet to be determined with outcome-oriented data. The study objective is to investigate the characteristics and outcomes of screening-detected lung cancers. METHODS This single-institution retrospective study included LCS patients between June 2014 and December 2019. Patient demographics, number of screening rounds, imaging features, clinical workup, disease extent, histopathology, treatment, complications, and mortality outcomes of screening-detected lung cancers were extracted and compared with NLST data. RESULTS LCS LDCTs (7,480) were performed on 4,176 patients. The cancer detection rate was 3.8%, higher than reported by NLST (2.4%, P < 0.0001), and cancers were most often found in patients ≥65 years (62%), older than those in NLST (41%, P < 0.0001). The patients' ethnicity was similar to NLST, P = 0.87. Most LCS-detected cancers were early stage I tumors (71% vs. 54% in NLST, P < 0.0001). Two thirds of cancers were detected in the first round of screening (67.1%) and were multifocal lung cancers in 15%. As in NLST, the complication rate after invasive workup or surgery was low (24% vs. 28% in NLST, P = 0.32). Over a median follow-up of 3.3 years, the mortality rate was 0.45%, lower than NLST (1.33%, P < 0.0001). CONCLUSIONS LCS implementation achieved a higher cancer detection rate, detection of early-stage cancers, and more multifocal lung cancers compared with the NLST, with low complications and mortality. IMPACT The real-world implementation of LCS has been successful for detection of lung cancer with favorable outcomes.

Abstract
PURPOSE The aim of this study was to estimate the incidence of colorectal cancers in Iran. The results of this study are based on a screening program that is being implemented in Isfahan province. MATERIAL AND METHODS In this study, about 137,000 people were screened for colorectal cancer and adenomatous polyps in 2 steps during the year 2018. RESULTS Based on the findings of this study, the incidence of adenomatous polyps was reported to be 389 (95% CI, 365-422) per 100,000 population. The incidence of adenomatous polyps was reported to be 483 (95% CI, 446-520) and 316 (95% CI, 286-346) in men and women, respectively (p < 0.001). Also, the incidence of colorectal cancer was reported to be 33 (95% CI, 23-42) per 100,000 population. The incidence of colorectal cancer in men and women was reported to be 41 (95% CI, 30-51) and 26 (95% CI, 17-34), respectively, indicating a statistically non-significant difference (p = 0.29). CONCLUSION Based on the result of this study, despite a low participation rate of the target population in the screening program, the incidence of adenomatous polyps and colorectal cancer is relatively high in the average-risk population.

Abstract
INTRODUCTION Colorectal cancer (CRC) does not affect different sociodemographic groups uniformly. CRC screening programmes could seek to reduce this inequality; however, the screening programmes themselves might be subject to differential participation across sociodemographic groups. This study investigates the sociodemographic inequality at all steps in Denmark's nationwide CRC screening programme: screening participation, faecal immunochemical test (FIT) results, colonoscopy compliance, CRC diagnosis, and cancer stage. MATERIAL AND METHODS This cohort study includes all first-time invitees from the beginning of the Danish population-based CRC screening programme from 1 March 2014 to 31 December 2017. RESULTS Sixty-four percent of the invitees participated in the screening programme, and of those 7% were FIT-positive. After being invited to further diagnostic procedures, 90% responded to the invitation, and among those 5% were CRC-positive. Among those diagnosed with CRC, 9% were stage IV. Through multivariable analyses, we identified sociodemographic inequalities in all steps of the screening programme from returning a stool sample to being diagnosed with CRC. Specifically, we identified inequalities across sex, age, migration status, relationship status, the screening status of one's partner, education, income, and use of health services. Women were more likely to participate compared to men (RR = 1.13; 95% CI: 1.12-1.13), but had a lower risk of a positive FIT result (RR = 0.67; 95% CI: 0.66-0.68) and of a CRC diagnosis (RR = 0.88; 95% CI: 0.82-0.93) compared to men. The likelihood of participating as well as the risk of positive FIT results and CRC diagnosis increased with age. CONCLUSION All steps of the screening programme were subject to sociodemographic inequalities. Interventions are needed to target groups identified as having lower uptake as well as high-risk of being FIT- and/or CRC-positive. These groups include males, individuals aged 60+ years and individuals who do not visit their GP regularly.

Abstract
OBJECTIVE Cancer screening should be equitably accessed by all populations. Uptake of colorectal cancer screening was examined using the Scottish Health and Ethnicity Linkage Study that links the Scottish Census 2001 to health data by individual-level self-reported ethnicity and religion. SETTING Data on 1.7 million individuals in two rounds of the Scottish Bowel Cancer Screening Programme (2007-2013) were linked to the 2001 Census using the Scottish Community Health Index number. MAIN OUTCOME MEASURE Uptake of colorectal cancer screening, reported as age-adjusted risk ratios (RRs) by ethnic group and religion were calculated for men and women with 95% CI. RESULTS In the first, incidence screening round, compared with white Scottish men, Other White British (RR 109.6, 95% CI 108.8 to 110.3) and Chinese (107.2, 95% CI 102.8 to 111.8) men had higher uptake. In contrast, men of all South Asian groups had lower uptake (Indian RR 80.5, 95% CI 76.1 to 85.1; Pakistani RR 65.9, 95% CI 62.7 to 69.3; Bangladeshi RR 76.6, 95% CI 63.9 to 91.9; Other South Asian RR 88.6, 95% CI 81.8 to 96.1). Comparable patterns were seen among women in all ethnic groups, for example, Pakistani (RR 55.5, 95% CI 52.5 to 58.8). Variation in uptake was also observed by religion, with lower rates among Hindu (RR (95%CI): 78.4 (71.8 to 85.6)), Muslim (69.5 (66.7 to 72.3)) and Sikh (73.4 (67.1 to 80.3)) men compared with the reference population (Church of Scotland), with similar variation among women: lower rates were also seen among those who reported being Jewish, Roman Catholic or with no religion. CONCLUSIONS There are important variations in uptake of bowel cancer screening by ethnic group and religion in Scotland, for both sexes, that require further research and targeted interventions.

Abstract
Objective: Colorectal cancer (CRC) is the third most commonly diagnosed cancer in Oman after breast and thyroid. Awareness regarding the availability of CRC screening services could play a major role in promoting early detection and reducing mortality rates. The aim of this study was to identify public knowledge and attitudes toward CRC screening. Methods: This cross-sectional study was conducted among 410 members of the public attending the Sultan Qaboos University Hospital in Muscat, Oman. A questionnaire was developed to assess the participants’ general knowledge, barriers and factors affecting attitudes, beliefs and behaviors regarding CRC screening. Results: A total of 410 members of the public participated from 500 invited (response rate: 82.0%). Most of the participants had not heard of CRC screening (76.3%) and were unaware of different screening methods (92.9%). The majority (93.9%) had not undergone CRC screening in Oman; however, 70.6% reported that they would be willing to do so in the future, particularly if recommended by doctors (52.7%). Barriers to screening included feeling embarrassed by the idea of a colonoscopy (73.9%), not having any symptoms of CRC (65.1%) and a fear of being diagnosed with CRC (55.6%). A bivariate analysis indicated that males demonstrated significantly more awareness of CRC screening compared to females (64.9% versus 35.1%; p = 0.004) and younger participants (<40 years of age) were significantly more aware of CRC screening compared to their older counterparts (75.3% versus 24.7%; p = 0.025). Conclusions: The majority of public in Oman showed low knowledge and awareness of CRC screening and identified several emotional barriers that might result in poor participation should screening be considered. Public education and the involvement of healthcare professionals is paramount to the implementation of a large-scale CRC screening program in Oman. In addition, addressing the sources of emotional barriers to screening is necessary.

Abstract
The purpose of this meta-analysis was to assess the usefulness of volatile organic compounds (VOC) as a potential novel biomarker for colorectal cancer (CRC).We systematically searched PubMed, Embase, Web of Science, and Cochrane Library databases for observational studies (published before November 25th, 2019; no language restrictions) comparing the VOC analysis between patients with CRC and healthy controls. We evaluated the pooled sensitivity, specificity, diagnostic odds ratio, positive and negative likelihood ratio, as well as summary receiver operating characteristic curve and area under the curve.We identified a total of 10 observational studies that included 381 patients with CRC and 436 healthy controls. Bivariate analysis yielded a pooled sensitivity of 0.82 (95% confidence interval [CI] = 0.77-0.86), specificity of 0.79 (95% CI = 0.71-0.85), positive likelihood ratio of 3.8 (95% CI = 2.8-5.3), and negative likelihood ratio of 0.23 (95% CI = 0.17-0.30). The area under the curve was 0.87 (95% CI = 0.84-0.90). The pooled diagnostic odds ratio was 17 (95% CI = 10-28). Sensitivity analysis indicated that the pooled results were stabilized. The Deeks' funnel plot asymmetry test (P = .41) suggested no potential publication bias.Our pooled data confirmed the associations between VOC analysis and CRC, highlighting the usefulness of VOC analysis as a potential novel screening tool for CRC. However, standardization of VOC collection and analysis methods for CRC screening is required in future research.

Abstract
Colorectal cancer (CRC) represents a global public health concern. CRC screening is associated with significant reductions in CRC incidence and mortality, however, uptake is suboptimal. This systematic review and meta-analysis of randomised controlled trials explored the effectiveness of interventions designed to increase screening uptake, plus the impact of various moderators. Data from 102 studies including 1.94 million participants were analysed. Results showed significant benefit of all interventions combined (OR, 1.49, 95% CI: 1.43, 1.56, p < 0.001). The effects were similar in studies using objective versus self-reported uptake measures and lower in studies judged to be at high risk of bias. Moderator analyses indicated significant effects for aspects of behaviour (effects lower for studies on non-endoscopic procedures), and intervention (effects higher for studies conducted in community settings, in healthcare systems that are not free, and that use reminders, health-professional providers, paper materials supplemented with in-person or phone contact, but avoid remote contact). Interventions that included behaviour change techniques targeting social support (unspecified or practical), instructions or demonstration of the behaviour, and that added objects to the environment produced stronger effects. The way in which findings can inform interventions to improve CRC screening uptake is discussed.

Abstract
OBJECTIVE Screening programmes based on the faecal occult blood test (FOBT) can reduce mortality from colorectal cancer (CRC). However, a significant variation exists in uptake of the test within the UK. Disproportionate uptake risks increasing inequity during staging at diagnosis and survival from CRC. This study aims to evaluate the impact of socioeconomic deprivation on the uptake of CRC screening (FOBT) in London. METHODS A retrospective review of the "Vanguard RM Informatics" database was performed to identify eligible individuals for CRC screening across all general practices across London over 30 months (2014-2017). The postcodes of the general practices were used to obtain the deprivation data via the "Indices of Deprivation" database. A Spearman's rho correlation was performed to quantify the impact of the deprivation variables on FOBT uptake. RESULTS Overall, 697,402 individuals were eligible for screening across 1359 London general practices, within 5 Clinical Commissioning Groups (CCGs); 48.4% (range: 13%-74%) participated in CRC screening with the lowest participation rates in North West (46%) and North East (47%) London CCGs. All indices of deprivation had a significant correlation with the uptake of FOBT (p < 0.01). CONCLUSION This is the largest study across London to date demonstrating a significant positive correlation between deprivation indices and FOBT uptake, highlighting areas of particular risk. Further studies are imperative to quantify the impact of deprivation on CRC morbidity and mortality, together with focused strategies to reduce socioeconomic inequalities in screening in these high risk areas.

Abstract
Screening with fecal occult blood tests (FOBT) reduces colorectal cancer mortality. Failure to complete repeat tests may compromise screening effectiveness. We conducted a systematic review of repeat FOBT across diverse health care settings. We searched MEDLINE, Embase, and the Cochrane Library for studies published from 1997 to 2017 and reported repeat FOBT over ≥2 screening rounds. Studies (n = 27 reported in 35 articles) measured repeat FOBT as (i) proportion of Round 1 participants completing repeat FOBT in Round 2; (ii) proportion completing two, consecutive FOBT; or (iii) proportion completing ≥3 rounds. Among those who completed FOBT in Round 1, 24.6% to 89.6% completed repeat FOBT in Round 2 [median: 82.0%; interquartile range (IQR): 73.7%-84.6%]. The proportion completing FOBT in two rounds ranged from 16.4% to 80.0% (median: 46.6%; IQR: 40.5%-50.0%), and in studies examining ≥3 rounds, repeat FOBT ranged from 0.8% to 64.1% (median: 39.2%; IQR: 19.7%-49.4%). Repeat FOBT appeared higher in mailed outreach (69.1%-89.6%) compared with opportunistic screening (24.6%-48.6%). Few studies examined correlates of repeat FOBT. In summary, we observed a wide prevalence of repeat FOBT, and prevalence generally declined in successive screening rounds. Interventions that increase and maintain participation in FOBT are needed to optimize effectiveness of this screening strategy.

Abstract
Implementation of population-based colorectal cancer screening programs by
Medicaid health plans could address colorectal cancer screening disparities. Our
objective is to identify facilitators and barriers to implementation of a
population-based colorectal cancer screening program by Washington State
Medicaid health plans. We conducted semi-structured interviews with leadership
from 2 statewide and 3 national Medicaid plans. We organized the interview
questions around the Consolidated Framework for Implementation Research (CFIR).
We analyzed interview transcripts, guided by directed content analysis, and
identified facilitators and barriers to Medicaid health plan implementation of
population-based colorectal cancer screening programs. Robust health plan (inner
setting) quality improvement infrastructures were facilitators. Lack of
statewide Medicaid policy incentives (external setting) to increase colorectal
cancer screening were barriers to potential implementation. Efforts to address
identified barriers through local and national policies and statewide data
sharing efforts may support Medicaid health plan implementation of
population-based colorectal cancer screening programs.

Abstract
AIM Although colorectal cancer (CRC) screening reduces mortality and morbidity the uptake in target populations is suboptimal. The aim was to assess whether adding a brief phone intervention to the usual invitation process increases participation in a CRC screening programme based in Catalonia. METHOD This was a non-blinded prospective randomized control study of patients eligible for their first CRC screening test (immunochemical faecal occult blood test). Between March and December 2017, 512 invitees (age range 50-69 years) were randomized to receiving either a brief informative phone call prior to receiving the standard screening invitation (letter and informative brochure) or the standard screening invitation alone. The primary outcome was participation in the screening programme at 6 months. RESULTS In all, 492/512 patients (54.7% women; 45.3% men) could be analysed (239/256 intervention group; 253/256 control group). On an intention to treat basis, the intervention group (55% women; 45% men) saw an 11% increase in the participation rate (51.05% vs 40.32%, P = 0.017). The intervention was more effective in male patients (50.93% vs 33.91%, P = 0.01) and those patients aged between 50 and 54 years (54.32% vs 37.77%, P = 0.03). After adjusting for sex, age and geographic area, the benefit of the intervention remained statistically significant (adjusted OR 1.54, 95% CI 1.07-2.20). CONCLUSION Our data suggest that a brief, informative intervention by phone in addition to the usual invitation process is effective in increasing participation in a CRC screening programme. It may be a useful strategy to improve uptake in groups which are less likely to participate in CRC screening (clinicaltrials.gov NCT03082911).

Abstract
BACKGROUND Elderly patients aged at least 75 years old (Elderly_75), represent 45% of colorectal cancer (CRC) incidence. As others, the French Colorectal Cancer Screening Program (CRCSP) does not include Elderly_75. To date, there is little evidence to justify stopping screening at 74 years of age.
AIM To describe CRC fecal screening test completion after age 74, source (CRCSP/Provider ordered) and outcomes of these tests.
METHODS The study concerned 18704 Elderly_75 residing in eleven French districts (Ain, Doubs, Essonne, Haute-Saone, Hauts-de-Seine, Jura, Seine-Saint-Denis, Territoire-de-Belfort, Val-de-Marne, Val-d’Oise, Yonne), having performed a CRC screening test between January 2008 and December 2017. The tests performed in a circumstance of delayed response to a solicitation (DRS) from the local cancer screening managing center (Managing-Center) were distinguished from the tests non-solicited by the Managing-Center, performed after a recommendation by a General Practitioner (GP) or other provider ordered (RGP). DRS was any test realized by an Elderly_75 following an initial invitation from the Managing-Center with a maximum 24 mo after this invitation. Any Non-DRS test was considered RGP. The outcomes of these tests were described according to the circumstances of test completion.
RESULTS Of 18995 screening-tests were performed at ages: 75 (83.5%), 76-80 (13.4%) and > 80 (3.1%) years old. Elderly_75 performed the screening test in a circumstance of DRS (71.9%) or RGP (28.1%). The proportion of the tests that could not be analyzed and not restarted was 13.2%. For these unanalyzed tests, the reason was age-related in 78.0% of cases, related to the laboratory’s refusal to analyze the test of people aged ≥ 77. Reported colonoscopy completion rate was 81.3%. For those 575 people with reported colonoscopy, no complication was listed. 18.0% of the 366 Elderly_75 with lesions had no anteriority in the CRCSP. The neoplasia (124 Low-risk-polyps, 159 High-risk-polyps, 13 Unspecified-polyps and 70 CRCs) detection rate was 19.3/1000 Elderly_75 screened and the CRC detection rate was 3.7/1000 Elderly_75 screened.
CONCLUSION The high rate of colonoscopy completion after a positive test and the high proportion of screened lesions observed suggest that the lengthening of the screening period could allow significant detection of CRC and polyps that occur in Elderly_75 excluded from CRCSP.

Abstract
OBJECTIVE Despite considerable improvements, 5-year survival rates for colon cancer in the UK remain poor when compared with other socioeconomically similar countries. Variation in 5-year survival can be partly explained by higher rates of death within 3 months of diagnosis in the UK. This study investigated the characteristics of patients who died within 3 months of a diagnosis of colon cancer with the aim of identifying specific patient factors that can be addressed or accounted for to improve survival outcomes. DESIGN A retrospective case-control study design was applied with matching on age, sex and year diagnosed. Patient, disease, clinical and service characteristics of patients diagnosed with colon cancer in a UK region (2005-2010) who survived less than 3 months from diagnosis (cases) were compared with patients who survived between 6 and 36 months (controls). Patient and clinical data were sourced from general practice notes and hospital databases 1-3 years prediagnosis. RESULTS Being older (aged ≥78 years) and living in deprivation quintile 5 (OR=2.64, 95% CI 1.15 to 6.06), being unmarried and living alone (OR=1.64, 95% CI 1.07 to 2.50), being underweight compared with normal weight or obese (OR=3.99, 95% CI 1.14 to 14.0), and being older and living in a rural as opposed to urban area (OR=1.96, 95% CI 1.21 to 3.17) were all independent predictors of early death from colon cancer. Missing information was also associated with early death, including unknown stage, histological type and marital/accommodation status after accounting for other factors. CONCLUSION Several factors typically associated with social isolation were a recurring theme in patients who died early from colon cancer. This association is unexplained by clinical or diagnostic pathway characteristics. Socially isolated patients are a key target group to improve outcomes of the worst surviving patients, but further investigation is required to determine if being isolated itself is actually a cause of early death from colon cancer.

Abstract
OBJECTIVE To estimate the change in the participation rate and the change in neoplasia incidence before and after the change of the Fecal Occult Blood Test (FOBT) in the cohort included in the Colorectal Cancer Screening Program (CRCSP). METHODS Cohort of 279,210 people, aged 50-74 years, invited at least once before 2009, to participate in a CRCSP campaign. The participation rate and the cumulative neoplasia incidence were described on 4 campaigns (≤2008, 2009-2010, 2011-2012 and 2013-2014) with a Guaiac FOBT (gFOBT) and a first campaign (2015-2016) with a Fecal Immunochemical Test (FIT). The cumulative incidence was estimated by the actuarial method and its confidence interval by the Greenwood method. RESULTS The participation rate decreased from 32.7% (first gFOBT-campaign) to 24.4% (fourth gFOBT-campaign) then, made a significant bound in the FIT-campaign (28.4%; p < 0.001). 35.4% of the 965 high-risk-polyps screened in this cohort were detected in the FIT-campaign. CRC incidence gradually decreased from 0.4 to 0.1/1000 person-years from the first to the fourth gFOBT-campaign before reaching a bound to 0.4/1000 person-years in the FIT-campaign. CONCLUSION Although it was still below the minimum European target (45%), the participation rate has increased between the last gFOBT-campaign and FIT-campaign, justifying the impact of promotional campaigns and the acceptance of the new test by people and GPs. A decline in the neoplasia incidence was observed between the initial and the fourth gFOBT-campaign. The change from gFOBT to FIT between the fourth and fifth campaigns, was associated with a significant increase in detection of neoplasia.

Abstract
OBJECTIVE Barrett's oesophagus is a premalignant condition that occurs in the context of gastro-oesophageal reflux. However, most Barrett's cases are undiagnosed because of reliance on endoscopy. We have developed a non-endoscopic tool: the Cytosponge, which when combined with trefoil factor 3 immunohistochemistry, can diagnose Barrett's oesophagus. We investigated whether a quantitative methylation test that is not reliant on histopathological analysis could be used to diagnose Barrett's oesophagus. DESIGN Differentially methylated genes between Barrett's and normal squamous oesophageal biopsies were identified from whole methylome data and confirmed using MethyLight PCR in biopsy samples of squamous oesophagus, gastric cardia and Barrett's oesophagus. Selected genes were then tested on Cytosponge BEST2 trial samples comprising a pilot cohort (n=20 cases, n=10 controls) and a validation cohort (n=149 cases, n=129 controls). RESULTS Eighteen genes were differentially methylated in patients with Barrett'soesophagus compared with squamous controls. Hypermethylation of TFPI2, TWIST1, ZNF345 and ZNF569 was confirmed in Barrett's biopsies compared with biopsies from squamous oesophagus and gastric cardia (p<0.05). When tested in Cytosponge samples, these four genes were hypermethylated in patients with Barrett's oesophagus compared with patients with reflux symptoms (p<0.001). The optimum biomarker to diagnose Barrett's oesophagus was TFPI2 with a sensitivity and specificity of 82.2% and 95.7%, respectively. CONCLUSION TFPI2, TWIST1, ZNF345 and ZNF569 methylation have promise as diagnostic biomarkers for Barrett's oesophagus when used in combination with a simple and cost effective non-endoscopic cell collection device.

Abstract
Background The initial roll-out of the English Bowel (Colorectal) Cancer Screening programme, during 2006 and 2009, found uptake to be low (54%) and socially graded. The current analysis used data from 2010 to 2015 to test whether uptake is increasing and becoming less socially graded over time. Methods Postcode-derived area-level uptake of 4.4 million first-time invitees, stratified by gender and the year of the first invitation (2010–2015), was generated using the National Bowel Cancer Screening System. Data were limited to people aged 60–64 years. Binomial regression tested for variations in uptake by the year of invitation, gender, region, area-based socio-economic deprivation and area-based ethnic diversity. Results Overall, the first-time colorectal cancer (CRC) screening uptake across 6 years was 52% (n = 2,285,996/4,423,734) with a decline between 2010 and 2015 (53%, 54%, 52%, 50%, 49%, 49% respectively). Uptake continued to be socially graded between the most and the least deprived area-level socio-economic deprivation quintiles (43% vs 57%), the most and the least area-based ethnic diversity quintiles (41% vs 56%) and men and women (47% vs 56%). Multivariate analysis demonstrated the effects of year, deprivation, ethnicity and gender on uptake. The effect of deprivation was more pronounced in the most deprived area quintile between men and women (40% vs 47%) than the least deprived area quintile (52% vs 62% respectively). Conclusion We did not find evidence of change in uptake patterns in CRC screening since its initial launch 10 years ago. The programme is unlikely to realise its full public health benefits and is en route to widening inequalities in CRC outcomes. Colorectal cancer screening uptake among first-time invitees remains low at 52%. There is a worrying reduction in colorectal cancer screening uptake between 2010 and 2015. There is no evidence that the social inequalities in uptake have reduced over time. There is no evidence of diffusion of innovation in colorectal cancer screening uptake in England.

Abstract
AIM The delivery of the Scottish Bowel Screening Programme (SBoSP) is rooted in the provision of a high quality, effective and participant-centred service. Safe and effective colonoscopy forms an integral part of the process. Additional accreditation as part of a multi-faceted programme for participating colonoscopists, as in England, does not exist in Scotland. This study aimed to describe the quality of colonoscopy in the SBoSP and compare this to the English national screening standards. METHODS Data were collected from the SBoSP between 2007 and 2014. End-points for analysis were caecal intubation, cancer, polyp and adenoma detection, and complications. Overall results were compared with 2012 published English national standards for screening and outcomes from 2006 to 2009. RESULTS During the study period 53 332 participants attended for colonoscopy. The colonoscopy completion rate was 95.6% overall. The mean cancer detection rate was 7.1%, the polyp detection rate was 45.7% and the adenoma detection rate was 35.5%. The overall complication rate was 0.47%. CONCLUSION Colonoscopy quality in the SBoSP has exceeded the standard set for screening colonoscopy in England, despite not adopting a multi-faceted programme for screening colonoscopy. However, the overall adenoma detection rate in Scotland was 9.1% lower than that in England which has implications for colonoscopy quality and may have an impact on cancer prevention rates, a key aim of the SBoSP.

Abstract
OBJECTIVE Our aim was to investigate why participants opted out of colonoscopy following a positive screening result for colorectal cancer. DESIGN Semi-structured, qualitative, single interviews. We audio-recorded and transcribed all interviews verbatim and used Strauss and Corbin's concept of open, axial, and selective coding to identify the main categories shared across all interviews. These formed the basis of our findings. SETTING A Danish national colorectal cancer screening programme. SUBJECTS Single interviews with 13 participants who declined to have a colonoscopy. MAIN OUTCOME MEASURES Reasons to decline colonoscopy after positive screening test. RESULTS Participants gave 42 different reasons for deciding not to have a colonoscopy and we coded them into nine main categories; Practical barriers, Discomfort of the examination, Personal integrity, Multimorbidity, Feeling healthy, Not having the energy, Belief that cancer is not present, Risk of complications, and Distrust in the accuracy of the iFOBT. CONCLUSIONS Our findings suggest that some practical barriers could be quite easily addressed, by offering the participants alternative management and procdures. IMPLICATIONS Further research is needed to examine how widely our findings are represented in the general population, and how general practitioners should consult with patients who have opted out of colonoscopy, despite a positive screening result. Key points Some screening participants are reluctant to proceed with further diagnostic tests for colorectal cancer following a positive screening result. • Interviews with people, who had refused a follow-up colonoscopy, discovered nine categories (42 reasons) of reasons for refusal. • Reluctance can be addressed by offering support with pre-procedure preparations and alternatives to colonoscopy. • General practitioners face ethical dilemmas and challenges, when patients at risk of colorectal cancer decline to proceed with screening.

Abstract
OBJECTIVE Colorectal cancer (CRC) screening programmes can reduce CRC mortality. However, the implementation of a screening programme may create or exacerbate socioeconomic and ethnic health inequities if participation varies by subgroup. We determined which organised programmes characterise participation inequities by socioeconomic and ethnic subgroups, and assessed the variation in subgroup participation among programmes collecting group-specific data. DESIGN Employing a literature review and survey among leaders of national or regional screening programmes, this study identified published and unpublished data on participation by socioeconomic status and ethnicity. We assessed programmes offering faecal occult blood tests (FOBT) for screening. Primary outcome was screening participation rate. RESULTS Across 24 organised FOBT-screening programmes meeting the inclusion criteria, participation rates ranged from 21% to 73%. Most programmes (13/24, 54%) did not collect data on participation by socioeconomic status and ethnicity. Among the 11 programmes with data on participation by socioeconomic status, 90% (28/31 publications) reported lower participation among lower socioeconomic groups. Differences across socioeconomic gradients were moderate (66% vs 71%) to severe (35% vs 61%). Only six programmes reported participation results by ethnicity. Ethnic differences were moderate, though only limited data were available for evaluation. CONCLUSIONS Across organised CRC screening programmes worldwide, variation in participation by socioeconomic status and ethnicity is often not assessed. However, when measured, marked disparities in participation by socioeconomic status have been observed. Limited data were available to assess inequities by ethnicity. To avoid exacerbating health inequities, screening programmes should systematically monitor participation by socioeconomic status and ethnicity, and investigate and address determinants of low participation.

Abstract
Purpose To compare the cost-effectiveness of computed tomographic (CT) colonography and colonoscopy screening by using data on unit costs and participation rates from a randomized controlled screening trial in a dedicated screening setting. Materials and Methods Observed participation rates and screening costs from the Colonoscopy or Colonography for Screening, or COCOS, trial were used in a microsimulation model to estimate costs and quality-adjusted life-years (QALYs) gained with colonoscopy and CT colonography screening. For both tests, the authors determined optimal age range and screening interval combinations assuming a 100% participation rate. Assuming observed participation for these combinations, the cost-effectiveness of both tests was compared. Extracolonic findings were not included because long-term follow-up data are lacking. Results The participation rates for colonoscopy and CT colonography were 21.5% (1276 of 5924 invitees) and 33.6% (982 of 2920 invitees), respectively. Colonoscopy was more cost-effective in the screening strategies with one or two lifetime screenings, whereas CT colonography was more cost-effective in strategies with more lifetime screenings. CT colonography was the preferred test for willingness-to-pay-thresholds of €3200 per QALY gained and higher, which is lower than the Dutch willingness-to-pay threshold of €20 000. With equal participation, colonoscopy was the preferred test independent of willingness-to-pay thresholds. The findings were robust for most of the sensitivity analyses, except with regard to relative screening costs and subsequent participation. Conclusion Because of the higher participation rates, CT colonography screening for colorectal cancer is more cost-effective than colonoscopy screening. The implementation of CT colonography screening requires previous satisfactory resolution to the question as to how best to deal with extracolonic findings. © RSNA, 2018 Online supplemental material is available for this article.

Abstract
Objective To understand the usage and acceptability of a faecal collection device amongst participants in the National Health Service Bowel Cancer Screening Programme, with the aim of influencing future uptake. Setting Participants completing faecal occult blood test retests as part of the routine Bowel Cancer Screening Programme in Eastern England. Methods A faecal collection device and questionnaire were sent to all potential retest participants during a one-month period to collect information on prior stool collection methods and ease of use and usefulness of the enclosed faecal collection device. Results Out of 1087 participants invited, 679 (62.5%) returned their questionnaire. Of these, 429 (63.2%) trialled the faecal collection device at least once, 163 (38.4%) found the device made collecting their sample easier than previously, 189 (44.6%) found it made collection more difficult and 72 (17.0%) said it made no difference. Similar numbers reported finding that the faecal collection device made collecting the sample more pleasant (130, 31.5%), less pleasant (103, 25.0%) and no different (179, 43.4%) compared with previous collection without a faecal collection device. Conclusion Although a small proportion of participants found the faecal collection device helpful, a considerable majority did not or did not use it at all. Offering faecal collection devices is unlikely to produce a substantial increase in bowel cancer screening uptake.

Abstract
Reminders have been used in various settings, but failed to produce convincing evidence of benefits on patient adherence to colorectal cancer (CRC) screening. The aim of this study was to assess the effectiveness of sending general practitioners (GPs) printed reminders about CRC screening. We conducted a cluster-randomized controlled trial involving 144 GPs in the Val-de-Marne district (France), who provided care for any reason to 20 778 patients eligible for CRC screening between June 2010 and November 2011. Data were collected from the main statutory health-insurance programme and local cancer screening agency. GPs were randomly assigned in a 1 : 1 proportion to the intervention or the control group. Every 4 months, intervention-group GPs received a computer-generated printed list of patients who had not performed scheduled faecal occult blood test (FOBT) screening. The primary outcome was patient adherence to FOBT screening or exclusion from CRC screening for medical reasons. The screening adherence rate was 31.2% [95% confidence interval (CI) 30.3-32.1] in the control group and 32.9% (95% CI 32.0-33.8) in the intervention group [crude relative risk, 1.05 (95% CI 1.01-1.09), P<0.01]. This rate was not significantly different between groups by multilevel modelling accounting for clustering and confounding variables [adjusted relative risk, 1.07 (95% CI 0.95-1.20), P=0.27]. Computer-generated printed reminders sent to GPs did not significantly improve patient adherence to organized CRC screening by the FOBT.

Abstract
BACKGROUND Early detection of colorectal cancer (CRC) is important to achieve better survival. Discriminating symptoms suggestive of CRC from benign conditions is a challenge for GPs because most known 'alarm symptoms' have low predictive values. AIM To further understand the diagnostic process of CRC in general practice in terms of healthcare use and by analysing factors related to diagnostic intervals. DESIGN AND SETTING A multimethod approach comprising a historical, prospective registry study and qualitative content analysis. METHOD Healthcare use in the year before referral for colonoscopy was compared between patients diagnosed with CRC and an age-, sex,- and GP-matched control population. Qualitative content analysis was performed on free texts in electronic patient records from a purposive sample of patients with CRC. RESULTS Patients with CRC (n = 287) had 41% (25-59%) more face-to-face contacts and 21% (7-37%) more medication prescriptions than controls (n = 828). Forty-six per cent of patients with CRC had two or more contacts for digestive reasons, compared with 12.2% of controls, more often for symptoms than diagnoses. From qualitative analysis two themes emerged: 'possible missed diagnostic opportunities' and 'improvements in diagnostic process unlikely'. Possible missed diagnostic opportunities were related to patients waiting before presenting symptoms, doctors attributing symptoms to comorbid conditions or medication use, or doctors sticking to an initial diagnosis. CONCLUSION Fewer missed diagnostic opportunities might occur if GPs are aware of pitfalls in diagnosing CRC: the assumption that symptoms are caused by comorbid conditions or medication, or relating complaints to pre-existing medical conditions. GPs also need to be aware that repeated digestive complaints warrant rethinking an earlier diagnosis.

Abstract
AIM We have introduced 'straight-to-test' (STT) colonoscopy as part of our 2-week-wait (2WW) pathway to address increasing numbers of urgent referrals for colorectal cancer (CRC) within the National Health Service. In this study we evaluated the ability of this initiative to shorten the time to diagnosis of CRC. METHOD We amended our 2WW referral form to include performance status and comorbidities. General practitioners were asked to provide data on estimated glomerular filtration rate and full blood count/ferritin. Our 2WW referrals were screened by a colorectal consultant and a nurse specialist. Those deemed unsuitable for STT were offered outpatient assessment (OPA). RESULTS Of 553 2WW referrals screened, 352 were considered suitable, 65 of whom failed a telephone assessment or were uncontactable, and accordingly 287 were offered the STT pathway. The STT group was significantly younger than the OPA group (median 65.9 years vs 78.7 years; P < 0.0001). STT colonoscopy significantly reduced the time to first test (13 days vs 22 days; P < 0.0001) and tissue diagnosis from the referral date (17 days vs 24.5 days; P < 0.0001). Thirty-seven (6.8%) CRCs were detected. Proportionately fewer patients in the STT pathway were managed with 'best supportive care only' compared with patients attending OPA (one of 15 vs six of 22, respectively). STT colonoscopy obviated the need for clinic attendance before testing in 287 patients, representing a potential net cost benefit of at least £48 500 in 4 months. CONCLUSION STT colonoscopy was safe and effective for selecting out a group of symptomatic patients who could proceed straight to endoscopic examination and receive a diagnosis more rapidly.

Abstract
INTRODUCTION Fecal occult blood tests are recommended for colorectal cancer (CRC) screening in Europe. Recently, the fecal immunochemical test (FIT) has come into use. Sociodemographic differences between participants and nonparticipants may be less pronounced when using FIT as there are no preceding dietary restrictions and only one specimen is required. The aim of this study was to examine the associations between sociodemographic characteristics and nonparticipation for both genders, with special emphasis on those who actively unsubscribe from the program. METHODS The study was a national, register-based, cross-sectional study among men and women randomized to be invited to participate in the prevalence round of the Danish CRC screening program between March 1 and December 31, 2014. Prevalence ratios (PRs) were used to quantify the association between sociodemographic characteristics and nonparticipation (including active nonparticipation). PRs were assessed using Poisson regression with robust error variance. RESULTS The likelihood of being a nonparticipant was highest in the younger part of the population; however, for women, the association across age groups was U-shaped. Female immigrants were more likely to be nonparticipants. Living alone, being on social welfare, and having lower income were factors that were associated with nonparticipation among both men and women. For both men and women, there was a U-shaped association between education and nonparticipation. For both men and women, the likelihood of active nonparticipation rose with age; it was lowest among non-western immigrants and highest among social welfare recipients. CONCLUSION Social inequality in screening uptake was evident among both men and women in the Danish CRC screening program, even though the program is free of charge and the screening kit is based on FIT and mailed directly to the individuals. Interventions are needed to bridge this gap if CRC screening is to avoid aggravating existing inequalities in CRC-related morbidity and mortality.

Abstract
Computed tomographic colonography (CTC) is a minimally invasive imaging examination for the colon, and is safe, well tolerated and accurate for the detection of colorectal cancer (CRC) and advanced adenoma. While the role of CTC as a primary test for population screening of CRC is under investigation, the fecal occult blood test (FOBT) has been recommended for population screening of CRC in Europe. Subjects with positive FOBT are invited to undergo total colonoscopy, which has some critical issues, such as suboptimal compliance, contraindications and the possibility of an incomplete exploration of the colon. Based on available data, the integration of CTC in FOBT-based population screening programs for CRC may fall into three scenarios. First, CTC is recommended in FOBT-positive subjects when colonoscopy is refused, incomplete or contraindicated. For these indications CTC should replace double-contrast barium enema. Second, conversely, CTC is not currently recommended as a second-level examination prior to colonoscopy in all FOBT-positive subjects, as this strategy is most probably not cost-effective. Finally, CTC may be considered instead of colonoscopy for surveillance after adenoma removal, but specific studies are needed.

Abstract
Background Screening participants with abnormal faecal occult blood test results who do not attend further testing are at high risk of colorectal cancer, yet little is known about their reasons for non-attendance. Methods We conducted a medical record review of 170 patients from two English Bowel Cancer Screening Programme centres who had abnormal guaiac faecal occult blood test screening tests between November 2011 and April 2013 but did not undergo colonoscopy. Using information from patient records, we coded and categorized reasons for non-attendance. Results Of the 170 patients, 82 were eligible for review, of whom 66 had at least one recorded reason for lack of colonoscopy follow-up. Reasons fell into seven main categories: (i) other commitments, (ii) unwillingness to have the test, (iii) a feeling that the faecal occult blood test result was a false positive, (iv) another health issue taking priority, (v) failing to complete bowel preparation, (vi) practical barriers (e.g. lack of transport), and (vii) having had or planning colonoscopy elsewhere. The most common single reasons were unwillingness to have a colonoscopy and being away. Conclusions We identify a range of apparent reasons for colonoscopy non-attendance after a positive faecal occult blood test screening. Education regarding the interpretation of guaiac faecal occult blood test findings, offer of alternative confirmatory test options, and flexibility in the timing or location of subsequent testing might decrease non-attendance of diagnostic testing following positive faecal occult blood test.

Abstract
BackgroundBowel cancer screening reduces cancer-specific mortality. There is a socioeconomic gradient in the uptake of the English NHS Bowel Cancer Screening Programme (BCSP), which may lead to inequalities in cancer outcomes.ObjectiveTo reduce socioeconomic inequalities in uptake of the NHS BCSP’s guaiac faecal occult blood test (gFOBt) without compromising uptake in any socioeconomic group.DesignWorkstream 1 explored psychosocial determinants of non-uptake of gFOBt in focus groups and interviews. Workstream 2 developed and tested four theoretically based interventions: (1) ‘gist’ information, (2) a ‘narrative’ leaflet, (3) ‘general practice endorsement’ (GPE) and (4) an ‘enhanced reminder’ (ER). Workstream 3 comprised four national cluster randomised controlled trials (RCTs) of the cost-effectiveness of each intervention.MethodsInterventions were co-designed with user panels, user tested using interviews and focus groups, and piloted with postal questionnaires. RCTs compared ‘usual care’ (existing NHS BCSP invitations) with usual care plus each intervention. The four trials tested: (1) ‘gist’ leaflet (n = 163,525), (2) ‘narrative’ leaflet (n = 150,417), (3) GPE on the invitation letter (n = 265,434) and (4) ER (n = 168,480). Randomisation was based on day of mailing of the screening invitation. The Index of Multiple Deprivation (IMD) score associated with each individual’s home address was used as the marker of socioeconomic circumstances (SECs). Change in the socioeconomic gradient in uptake (interaction between treatment group and IMD quintile) was the primary outcome. Screening uptake was defined as the return of a gFOBt kit within 18 weeks of the invitation that led to a ‘definitive’ test result of either ‘normal’ (i.e. no further investigation required) or ‘abnormal’ (i.e. requiring referral for further testing). Difference in overall uptake was the secondary outcome.ResultsThe gist and narrative trials showed no effect on the SECs gradient or overall uptake (57.6% and 56.7%, respectively, compared with 57.3% and 58.5%, respectively, for usual care; allp-values > 0.05). GPE showed no effect on the gradient (p = 0.5) but increased overall uptake [58.2% vs. 57.5% in usual care, odds ratio (OR) = 1.07, 95% confidence interval (CI) 1.04 to 1.10;p < 0.0001]. ER showed a significant interaction with SECs (p = 0.005), with a stronger effect in the most deprived IMD quintile (14.1% vs. 13.3% in usual care, OR = 1.11, 95% CI 1.04 to 1.20;p = 0.003) than the least deprived (34.7% vs. 34.9% in usual care OR = 1.00, 95% CI 0.94 to 1.06;p = 0.98), and higher overall uptake (25.8% vs. 25.1% in usual care, OR = 1.07, 95% CI 1.03 to 1.11;p = 0.001). All interventions were inexpensive to provide.LimitationsIn line with NHS policy, the gist and narrative leaflets supplemented rather than replaced existing NHS BCSP information. This may have undermined their effect.ConclusionsEnhanced reminder reduced the gradient and modestly increased overall uptake, whereas GPE increased overall uptake but did not reduce the gradient. Therefore, given their effectiveness and very low cost, the findings suggest that implementation of both by the NHS BCSP would be beneficial. The gist and narrative results highlight the challenge of achieving equitable delivery of the screening offer when all communication is written; the format is universal and informed decision-making mandates extensive medical information.Future workSocioculturally tailored research to promote communication about screening with family and friends should be developed and evaluated.Trial registrationCurrent Controlled Trials ISRCTN74121020.FundingThis project was funded by the National Institute for Health Research (NIHR) Programme Grants for Applied Research programme and will be published in full inProgramme Grants for Applied Research; Vol. 5, No. 8.

Abstract
The colon capsule endoscopy (CCE) was first introduced in 2007. Currently, the main clinical indications for CCE are completion of incomplete colonoscopy, polyp detection and investigation of inflammatory bowel disease (IBD). Although conventional colonoscopy is the gold standard in bowel cancer screening, incomplete colonoscopy remains a problem as lesions are missed. CCE compares favourably to computer tomography colonography (CTC) in adenoma detection and has therefore been proposed as a method for completing colonoscopy. However the data on CCE remains sparse and current evidence does not show its superiority over CTC or conventional colonoscopy in bowel cancer screening. CCE also seems to show good correlation with conventional colonoscopy when used to evaluate IBD, but there are not many published studies at present. Other significant limitations include the need for aggressive bowel preparation and the labour-intensiveness of CCE reading. Therefore, much further software and hardware development is required to enable CCE to fulfill its potential as a minimally-invasive and reliable method of colonoscopy.

Abstract
Background Ethnic and socio‐economic inequalities have been reported in the uptake of colorectal cancer (CRC) screening. This study aimed to explore the factors affecting CRC screening participation in an ethnically and socio‐economically diverse inner city population. Methods Semi‐structured interviews were undertaken with 50 people aged 55–74 years, recruited from GP practices in south‐east London. Participants were from Black African (n=13), Black Caribbean (n=15), White British (n=17), Black other (n=2) and White other (n=3) backgrounds. Participants' socio‐economic status (SES) was assessed using a combined measure of educational attainment, housing tenure and car ownership. Participants' SES varied although there were more participants from less deprived backgrounds than those from more deprived backgrounds. The interview topic guide was informed by the Theoretical Domains Framework. Interviews were recorded, transcribed and analysed using framework analysis. Findings Lack of awareness of CRC screening was a barrier for all participants. There were also some notable group differences by ethnicity and SES. Cancer fear was a barrier for White British participants of varying SES. Misunderstanding instructions for completing the guaiac faecal occult blood test (gFOBt) was a barrier for people of low SES regardless of ethnicity. For Black African and Black Caribbean participants, of any SES, religious faith and a perceived civic duty to participate in screening encouraged participation. Discussion and conclusions This is the first study to provide detailed information on the separate views of Black African and Black Caribbean participants about screening. Consideration of ethnicity and SES together also allowed us to identify pertinent barriers for particular groups that can be targeted to improve access to screening for those who wish to take part.

Abstract
Colorectal Carcinoma is the second biggest killer after lung and bronchial carcinoma. Due to its insidious onset and late manifestation of symptoms a national screening programme was started in 2006 within the UK. We present a rare case of colorectal adenocarcinoma mimicking osteosarcoma and presenting as hip pain at initial consultation in the orthopaedic clinic. Further adding to the rarity of this case is that of an apparent bony metastasis in isolation. Our case demonstrates the vital role that histological sampling plays in the diagnosis and treatment of carcinomatous disease. It also demonstrates the need to maintain high index of clinical suspicion, no matter how benign the presenting complaint may seem.

Abstract
INTRODUCTION National colorectal cancer screening, utilising a faecal occult blood test (FOBT), is now well established in the UK. The aim of this study was to define the screening characteristics of patients presenting to secondary care with symptoms of colorectal cancer and to assess the effect of screening outcome on subsequent symptomatic presentation. METHODS This was a retrospective analysis of all patients of screening age presenting within one calendar year in a tertiary trust via a two-week wait (2WW) pathway owing to suspicion of colorectal cancer. Colorectal cancer related outcomes were compared between patients in the cohort who had previously accepted bowel cancer screening and patients who had previously declined bowel cancer screening. The primary endpoint was overall incidence of colorectal neoplasia. Secondary endpoints included incidence of colorectal malignancy, cancer related mortality, cancer related outcomes and polyp related outcomes. RESULTS Overall, 2,227 patients presented via the 2WW pathway; 955 were aged 60-75 years. Among the latter, 411 (43%) had been screened previously and had a negative FOBT, and 544 (57%) had declined screening. Incidence of colorectal neoplasia did not differ between the two groups (113 [27%] vs 143 [26%], p=0.7). Of those with a negative FOBT and subsequent symptomatic presentation, 16 (3.9%) were diagnosed with a colorectal malignancy compared with 36 (6.6%) of those who declined screening and had subsequent symptomatic presentation (relative risk: 1.7, 95% confidence interval: 0.96-3.02, p=0.08). There were no differences between the two groups with regard to TNM (tumour, lymph nodes, metastasis) stage, Dukes' stage, metastases, number of polyps or cancer related mortality (median follow-up duration: 20 months). CONCLUSIONS The incidence of colorectal neoplasia was similar among patients who previously had a negative FOBT and those who declined screening. There was a higher incidence of colorectal cancer detected among those who declined screening but it did not reach statistical significance. All other cancer and polyp outcomes were similar between the groups.

Abstract
BACKGROUND While it is known that a variety of factors (biological, behavioural and interventional) play a major role in the health of individuals and populations, the importance of the role of social determinants is less clear. The effect of social inequality on population-based screening for colorectal cancer (CRC) could limit the value of such programmes. The present study aims to determine whether such inequalities exist. METHODS Data was obtained from the population-based screening programme administered in the Autonomous Community of the Basque Country, Spain, with a target population aged 50 to 69, first invited to participate between 2009 and 2011. The magnitude of inequality was analysed using the odds ratio (taking the least disadvantaged socioeconomic quintile as the reference population), the population attributable risk and the relative index of inequality, based on the regression, which is the ratio of the rates in the most and least disadvantaged socioeconomic groups. RESULTS The target population comprised 242,394 people, with the test kit successfully sent to 95.1 % (230,510). The overall response rate was 64.3 % (67.1 in women and 61.4 % men). Among women, the highest participation was in the third quintile (71.5 %) and the lowest in the first - the least disadvantaged (65.7 %). The lowest and highest rates of people with identified lesions were in the second and fourth quintiles (14.7/1000 and 17.0/1000 respectively). Among men, the response rate was lowest in the fifth - most disadvantaged - quintile (60.2 %). The highest rate of identified lesions was in the fifth quintile; 38 % higher than the first (55.7/1000 compared to 41.0/1000). CONCLUSIONS Sex and socioeconomic group influence the rate of participation in the CRC programme and the rate of lesions found in the participants. Any public health programme is morally and ethically obliged to strive for equity and effectiveness. Improving participation of men and socially disadvantaged groups should be taken in account.

Abstract
Background Colorectal cancer screening uptake within the South Asian population in England is approximately half that of the general population (33 % vs 61 %), and varies by Muslim (31.9 %), Sikh (34.6 %) and Hindu (43.7 %) faith background. This study sought to explore reasons for low uptake of CRC screening in South Asian communities and for the variability of low uptake between three faith communities; and to identify strategies by which uptake might be improved. Methods We interviewed 16 ‘key informants’ representing communities from the three largest South Asian faith backgrounds (Islam, Hinduism and Sikhism) in London, England. Results Reasons for low colorectal cancer screening uptake were overwhelmingly shared across South Asian faith groups. These were: limitations posed by written English; limitations posed by any written language; reliance on younger family members; low awareness of colorectal cancer and screening; and difficulties associated with faeces. Non-written information delivered verbally and interactively within faith or community settings was preferred across faith communities. Conclusions Efforts to increase accessibility to colorectal cancer screening in South Asian communities should use local language broadcasts on ethnic media and face-to-face approaches within community and faith settings to increase awareness of colorectal cancer and screening, and address challenges posed by written materials.

Abstract
BACKGROUND & AIMS Fecal immunochemical tests (FITs) are used widely in colorectal cancer screening. Programs use the same fecal hemoglobin threshold for colonoscopy referral for men and women, but it is unclear whether FIT performs equally in both sexes. We therefore assessed FIT performance in men and women. METHODS A prospective cohort study was performed, in which a total of 10,008 average-risk subjects (age, 50-74 y) were invited for first-round screening and 8316 average-risk subjects (age, 51-74 y) were invited for second-round screening with a single FIT. Subjects with a hemoglobin (Hb) level of 10 μg hemoglobin (Hb)/g (or ≥50 ng/mL) feces or higher were referred for colonoscopy. The test characteristics were assessed by sex for a range of FIT cut-off values. RESULTS In total, 59.8% of men and 64.6% of women participated in the first round (P < .001). At a cut-off level of 10 μg Hb/g feces, the positivity rate was significantly higher among men (10.7%) compared with women (6.3%; P < .001) in the first round. The detection rate of advanced neoplasia was 4.4% for men and 2.2% for women (P < .001) in the first round. The positive predictive value for advanced neoplasia in the first round was 42% for men and 37% for women (P = .265). A significantly higher false-positive rate in men (6.3%) than in women (4.1%; P < .001) was found. Similar differences in these test characteristics were seen in the second round. CONCLUSIONS At a cut-off level of 10 μg Hb/g feces the FIT positivity rate was higher in men, reflected by both a higher detection rate and a higher false-positive rate. The use of the same cut-off value in men and women in FIT screening is recommended based on equal test performance in terms of positive predictive value.

Abstract
Diagnosis of colorectal cancer is an invasive and expensive colonoscopy, which is usually carried out after a positive screening test. Unfortunately, existing screening tests lack specificity and sensitivity, hence many unnecessary colonoscopies are performed. Here we report on a potential new screening test for colorectal cancer based on the analysis of volatile organic compounds (VOCs) in the headspace of faecal samples. Faecal samples were obtained from subjects who had a positive faecal occult blood sample (FOBT). Subjects subsequently had colonoscopies performed to classify them into low risk (non-cancer) and high risk (colorectal cancer) groups. Volatile organic compounds were analysed by selected ion flow tube mass spectrometry (SIFT-MS) and then data were analysed using both univariate and multivariate statistical methods. Ions most likely from hydrogen sulphide, dimethyl sulphide and dimethyl disulphide are statistically significantly higher in samples from high risk rather than low risk subjects. Results using multivariate methods show that the test gives a correct classification of 75% with 78% specificity and 72% sensitivity on FOBT positive samples, offering a potentially effective alternative to FOBT.

Abstract
OBJECTIVES Positive rates in faecal immunochemical test (FIT)-based colorectal cancer screening programmes vary, suggesting that differences between programmes may affect test results. We examined whether demographic, pathological, behavioural, and environmental factors affected haemoglobin concentration and positive rates where samples are mailed. METHODS A retrospective cohort study; 34,298 collection devices were sent, over five years, to screening invitees (median age 60.6). Participant demographics, temperature on sample postage day, and previous screening were recorded. Outcomes from colonoscopy performed within a year following FIT were collected. Multivariate logistic regression identified significant predictors of test positivity. RESULTS Higher positive rate was independently associated with male gender, older age, lower socioeconomic status, and distally located neoplasia, and negatively associated with previous screening (p < 0.05). Older males had higher faecal haemoglobin concentrations and were less likely to have a false positive result at colonoscopy (p < 0.05). High temperature on the sample postage day was associated with reduced haemoglobin concentration and positivity rate (26-35℃: Odds ratio 0.78, 95% confidence interval 0.66-0.93), but was not associated with missed significant neoplasia at colonoscopy (p > 0.05). CONCLUSIONS Haemoglobin concentrations, and therefore FIT positivity, were affected by factors that vary between screening programmes. Participant demographics and high temperature at postage had significant effects. The impact of temperature could be reduced by seasonal scheduling of invitations. The importance of screening, and following up positive test results, particularly in older males, should be promoted.

Abstract
OBJECTIVES To estimate the impact of various expansion scenarios of the National Bowel Cancer Screening Program (NBCSP) on the number of bowel cancer deaths prevented; and to investigate the impact of the expansion scenarios on colonoscopy demand. DESIGN MISCAN-Colon, a well established, validated computer simulation model for bowel cancer screening, was adjusted to reflect the Australian situation. In July 2013, we simulated the effects of screening over a 50-year period, starting in 2006. The model parameters included rates of participation in screening and follow-up, rates of identification of cancerous and precancerous lesions, bowel cancer incidence, mortality and the outcomes of the NBCSP. Five implementation scenarios, based on biennial screening using an immunochemical faecal occult blood test, were developed and modelled. A sensitivity analysis that increased screening participation to 60% was also conducted. PARTICIPANTS Australian residents aged 50 to 74 years. MAIN OUTCOME MEASURES Comparison of the impact of five implementation scenarios on the number of bowel cancer deaths prevented and demand for colonoscopy. RESULTS MISCAN-Colon calculated that in its current state, the NBCSP should prevent 35 169 bowel cancer deaths in the coming 40 years. Accelerating the expansion of the program to achieve biennial screening by 2020 would prevent more than 70 000 deaths. If complete implementation of biennial screening results in a corresponding increase in participation to 60%, the number of deaths prevented will increase across all scenarios. CONCLUSIONS The findings strongly support the need for rapid implementation of the NBCSP. Compared with the current situation, achieving biennial screening by 2020 could result in 100% more bowel cancer deaths (about 35 000) being prevented in the coming 40 years.

Abstract
BACKGROUND Studies to date support the use of the faecal immunological test (FIT) in colorectal cancer screening programmes, and it has been widely adopted across Europe, Canada, Australia, and the USA. Successive screening rounds are necessary to detect and prevent colorectal cancer. The overall success of FIT screening will depend on several factors, the most important probably being the acceptability of repeated screening rounds. Being a newer form of occult blood testing, there is little data available on its overall efficacy over time. AIMS The aim of this study was to assess key performance indices during a second round of FIT screening in an Irish cohort and to compare results between successive rounds. METHODS A biennial, two tests, two-step design with postal invites and colonoscopy offered to anyone with a single FIT greater than 100 ngHb/ml was used. Recommended key performance measures were assessed and compared, including participation, positivity, colonoscopy uptake and adenoma and cancer detection rates. RESULTS In round two, 9863 individuals (98.6%) of the round one cohort were contacted. The round two participation rate was 47.5% (n=4685), only slightly lower than the 51% registered in round one. Male sex and younger age were associated with lower uptake. Overall positivity decreased from 10 to 8% over time (P<0.0001). Although the number of cancers detected during round two decreased significantly, overall neoplasia detection rates remained stable; positive predictive values for cancer and adenoma were 4 versus 1% and 37 versus 35%, respectively. CONCLUSION Repeated rounds of FIT screening in the Tallaght-Trinity College cohort achieved stable participation and neoplasia detection rates, suggesting that this mode of screening is both effective and acceptable to patients in the long term.
