Understanding patient factors to increase uptake of cancer screening: a review

Experiences of cancer-related stigma in Africa: A scoping review

Cancer is a major health issue, particularly in low- and middle-income countries where 70% of cancer deaths occur. Stigma and barriers to screening and treatment lead to poor outcomes. We conducted structured searches of PubMed, Embase, MEDLINE, CINAHL, and CABI Global Health databases according to PRISMA-ScR guidelines. Searches used keywords related to (1) Africa, (2) cancer, and (3) stigma. We then screened to finalize a list of research manuscripts, dissertations, theses, and conference abstracts using quantitative, qualitative, or mixed methods to explore cancer stigma in Africa. This review focused on non-cervical cancers. Breast and cervical cancers have distinct stigma-related experiences due to awareness, screening, and sociocultural perceptions. Including cervical cancer risks dilutes the specificity and depth of findings. The review included 53 studies that linked stigma and cancer in Africa to physical symptoms, appearance changes, misconceptions, and emotional challenges, hindering care and worsening treatment outcomes. Cancer-related stigma negatively impacts screening and treatment engagement in Africa. The lack of intervention studies underscores the need for evidence-based strategies to reduce stigma. Future efforts should reduce barriers to cancer care, enhance public awareness, and implement policy changes to improve outcomes.

Navigating the completing cancer treatment incentive in Malaysia: patient insights and implementation challenges

BACKGROUND

Cancer diagnosis imposes a significant economic burden on healthcare systems, patients, and their families particularly those from low-income households. To mitigate these challenges, Malaysia introduced the completing cancer treatment incentive (CCTI) under the PeKa B40 healthcare scheme to support cancer patients in completing their treatment. This study explores patients' experiences with the CCTI program to provide insights for refining policy interventions and enhancing the program's effectiveness in meeting the needs of its beneficiaries.

METHODS

This qualitative study examined the experiences of cancer patients with the CCTI program in Malaysia. Semi-structured interviews were conducted with 23 respondents, both CCTI recipients and non-applicants, from eight public hospitals. Data were anlaysed using the RE-AIM framework, focusing on the dimensions of reach, adoption, and implementation.

RESULTS

Patients' awareness of the CCTI varied, with recipients mostly informed through acquaintances, media, or healthcare providers. Non-recipients lacked awareness, with limited information provided by healthcare personnel. While the CCTI was perceived as valuable for alleviating financial burdens, particularly transportation costs, it did not appear to significantly influence treatment-seeking behaviours, as most patients expressed willingness to continue treatment even without financial aid. Implementation challenges included a burdensome application process requiring mandatory health screening, lack of clarity regarding procedures, and inadequate communication about claim approvals. Patients frequently encountered delays and confusion, exacerbated by insufficient support from healthcare providers. Additionally, many were unaware that transport incentives could be claimed for every hospital visit, further limiting the program's usefulness.

CONCLUSIONS

The study highlights critical gaps in the CCTI program's design and delivery, including inadequate communication strategies, complex administrative processes, and a lack of transparency. Addressing these challenges are essential to improve program reach and ensuring equitable access to CCTI. Policymakers should prioritise streamlining application process, enhancing information dissemination, and leveraging digital tools to improve patient experiences. Future studies should assess the program's long-term sustainability and impact on treatment adherence and outcomes. The findings underscore the importance of adopting patient-centred approaches in designing financial aid programs to enhance healthcare equity and access.

AI integrations with lung cancer screening: Considerations in developing AI in a public health setting

Lung cancer screening implementation has led to expanded imaging of the chest in older, tobacco-exposed populations. Growing numbers of screening cases are also found to have CT-detectable emphysema or elevated levels of coronary calcium, indicating the presence of coronary artery disease. Early interventions based on these additional findings, especially with coronary calcium, are emerging and follow established protocols. Given the pace of diagnostic innovation and the potential public health impact, it is timely to review issues in developing useful chest CT screening infrastructure as chest CT screening will soon involve millions of participants worldwide. Lung cancer screening succeeds because it detects curable, early primary lung cancer by characterizing and measuring changes in non-calcified, lung nodules in the size-range from 3mm to 15 mm in diameter. Therefore, close attention to imaging methodology is essential to lung screening success and similar image quality issues are required for reliable quantitative characterization of early emphysema and coronary artery disease. Today's emergence of advanced image analysis using artificial intelligence (AI) is disrupting many aspects of medical imaging including chest CT screening. Given these emerging technological and volume trends, a major concern is how to balance the diverse needs of parties committed to building AI tools for precise, reproducible, and economical chest CT screening, while addressing the public health needs of screening participants receiving this service. A new consortium, the Alliance for Global Implementation of Lung and Cardiac Early Disease Detection and Treatment (AGILEDxRx) is committed to facilitate broad, equitable implementation of multi-disciplinary, high quality chest CT screening using advanced computational tools at accessible cost.

Barriers to breast and cervical cancer screening among adolescent girls and young women in Kenya: A nationwide cross-sectional survey

Promoting regular screening remains one of the primary preventive measures for breast and cervical cancer. The study aimed to assess the prevalence and barriers to breast and cervical cancer screening among adolescent girls and young women (AGYW) in Kenya. The study used data from the 2022 Kenya Demographic and Health Survey (KDHS), with 12,026 AGYW who were selected by multistage sampling. The outcomes of interest were breast and cervical cancer screening. Multivariable logistic regression was used to assess factors negatively associated with the outcome variables, using SPSS (version 29.0). Of the 12,026 AGYW included in this study, only 6.0% (95%CI: 5.6-6.8) and 5.1% (95%CI: 4.8-6.0) had undertaken breast and cervical cancer screening, respectively. Low education (AOR = 0.08, 95%CI: 0.02-0.34 and AOR = 0.48, 95%CI: 0.28-0.83), not working (AOR = 0.67, 95%CI: 0.46-0.97 and AOR = 0.59, 95%CI: 0.42-0.82), low wealth index (AOR = 0.55, 95%CI: 0.32-0.92 and AOR = 0.45, 95%CI: 0.25-0.81), no visit to a healthcare facility in the last 6 months (AOR = 0.48, 95%CI: 0.33-0.69 and AOR = 0.50, 95%CI: 0.35-0.71), and no birth record (AOR = 0.29, 95%CI: 0.13-0.62 and AOR = 0.58, 95%CI: 0.27-0.74), were the major barriers to both breast and cervical cancer screening, respectively. Moreover, having no access to newspaper (AOR = 0.67, 95%CI: 0.46-0.97) was a significant barrier to breast cancer screening while having big problems with distance to a healthcare facility (AOR = 0.49, 95%CI: 0.33-0.73) and not using modern contraception (AOR = 0.60, 95%CI: 0.42-0.86) hindered cervical cancer screening. In conclusion, more efforts are needed from both the government and cancer stakeholders to increase accessibility of breast and cervical cancer screening services, especially to those with low social economic status. More targeted education and sensitization, improving livelihoods of AGYW through various women empowerment efforts, and improving screening capacity of low-grade healthcare facilities are among the useful strategies to improve the low screening rates.

The revised colorectal cancer screening guideline and screening burden at community health centers

Colorectal cancer (CRC) is the third most common cancer among men and women combined, and the second leading cause of cancer death in the US. The revised USPSTF CRC screening recommendations increased CRC screening needs across health systems, which may create particular challenges for community health centers (CHCs) given their resource constraints. The objective of our study is to assess CRC screening rates across 10 CHCs in Massachusetts and estimate the additional increase in the number of average-risk screening-eligible individuals after the revision in guidelines. CRC screening was defined as being up to date vs. not up to date based on any of the approved screening modalities in the appropriate time frame. Our outcome of interest was CRC screening by age group and the percentage increase in screenings needed to screen individuals 45 to 49 across our partner CHCs after the revision in guidelines. Our analysis included 70,808 individuals aged 45 to 75. The overall CRC screening rate was 35.9% after the USPSTF guideline revision. Screening rates were lowest in those aged 45 to 49 at 9.6%, and highest in those over age 55 at 47.0%. There was a 22.9% increase in additional screenings needed after USPSTF guideline revision. The revised USPSTF guidelines increased screening needs by about 23% without additional funding for CHCs for which demand already outstrips staffing and clinical care resources. Future studies should include cost analyses of screening the population 45 to 49 and identify effective strategies that are low burden and do not add to the workload of CHC providers to improve screening at CHCs.

Informed choices for some, but not for others: An exploration of Australian midlife women's participation in mammography screening by social class

BACKGROUND

Population-level mammography screening for early detection of breast cancer is a secondary prevention measure well-embedded in developed countries, and the implications for women's health are widely researched. From a public health perspective, efforts have focused on why mammography screening rates remain below the 70% screening rate required for effective population-level screening. From a sociological perspective, debates centre on whether 'informed choice' regarding screening exists for all women and the overemphasis on screening benefits, at the cost of not highlighting the potential harms. We dovetail these disciplinary agendas to contextualise the factors that impact mammography screening choices, interpreting screening status through a social class lens.

OBJECTIVE

To understand how social class impacts informed choice-making among midlife women (45-64 years), regarding (non) participation in mammography screening.

DESIGN

A qualitative study using semi-structured interviews.

METHODS

We interviewed 36 Australian midlife women from differing social class groups who were 'screeners' or 'non-screeners'. We conducted a theory-informed thematic analysis and used Bourdieu's relational social class theory to consider how women's access to social, cultural and economic capital influenced their screening identities. We conducted matrix and crosstab queries across themes to identify patterns by social class. We extend the findings from Friedman's study of women's screening perspectives as 'attentional' types utilising the 'sociology of attention'.

RESULTS

Our results map to Friedman's four 'attentional' types (default or conscious interventionists, conflicted or conscious sceptics), and we show how social class impacts women's attention to screening and participation. We show for middle-class women screening is a 'given', they align closely with normative screening expectations. Working-class women who screen, do so out of a sense of compliance. Affluent non-screeners make informed choices, while working-class women are more passive in their non-screening choices, being a group that sits outside of Friedman's four attentional types.

CONCLUSION

Current approaches to screening communication and programme delivery can be improved by tailoring approaches to reflect the impacts of social class in shaping women's 'choices'. Subsequently, equitable breast cancer prevention may be afforded, which impacts positively on population-level screening rates.

Evidence from Europe on implementation, participation and performance of self-collection for cervical cancer screening

Cervical cancer screening programs reduce the number of cervical cancer cases and deaths, but the success of any screening program is dependent on high participant uptake and coverage and many European countries are observing declining cervical cancer screening coverage to below national targets. Self-collection of vaginal samples for human papillomavirus testing, also termed self-sampling, is one strategy which is being introduced to try to increase screening coverage by removing barriers to participation and it has attracted growing interest and support globally. Informed by peer-reviewed and gray literature, this narrative review starts with a case study from the Netherlands and outlines the self-collection landscape in Europe within the themes of program implementation and relative test performance. It highlights some of the current evidence gaps needed to inform policy decisions on the use of self-collection within screening programs.

Social isolation, coping efficacy, and social well-being over time in patients with lung cancer

BACKGROUND

Little work has examined how coping efficacy and lung cancer-related social isolation relate to social well-being in the context of a patient's computed tomography (CT) scan. Researchers tested the cross-sectional relationship of social isolation and social well-being, and the longitudinal relationship between coping efficacy and social well-being before CT scans.

METHOD

25 patients with lung cancer, within 6 months of their upcoming CT scan, participated. Baseline surveys collected clinical information, demographics, and social isolation; repeated monthly surveys collected coping efficacy and social well-being every 30 days until one's scan.

RESULTS

[Cross-sectional] High levels of social isolation were associated with low levels of social well-being. [Longitudinal] On months patients reported high coping efficacy, they also reported increases in social well-being.

CONCLUSIONS

Social interventions may improve well-being among those with lung cancer as our work shows that getting and receiving support are strongly related to well-being in the time surrounding a scan.

Individual-level determinants of breast and cervical cancer screening and early testing in two regionally representative urban Indian populations

Introduction

Region-specific data on individual factors associated with uptake of breast and cervical cancer screening or early testing in diverse Indian populations are limited.

Aim

To assess the prevalence and individual determinants of uptake of breast and/or cervical cancer screening or testing among women aged 30-69 years in regionally representative populations of two large Indian cities: New Delhi and Chennai.

Methods

We conducted an analysis of the cross-sectional data (2016-2017) nested within the Centre for Cardiometabolic Risk Reduction in South Asia cohort, established in 2010-2011 with 12,271 participants (5365 in New Delhi; 6906 in Chennai). Among 3310 women participants, we evaluated the associations of demographic, socioeconomic, lifestyle, medical, psychosocial, and reproductive factors with breast and/or cervical cancer screening or testing using multivariable logistic regression models with results expressed as adjusted odds ratios (OR) and 95% confidence intervals (CI).

Results

At any point prior to 2016-2017, 193 women self-reported having undergone evaluations for breast and/or cervical cancer. The reasons for evaluation were 'general examination' or 'physician's advice' (i.e., screening) or 'being symptomatic' (i.e., early testing). The overall prevalence was 5.8% for screening or testing and 2.5% for screening alone. Formal education (OR:1.88; 95% CI:1.12-3.15), high monthly household income (OR:2.27; 95% CI:1.59-3.25) and less 'fear-of-judgement' (OR:1.65; 95% CI:1.05-2.58) were positively associated with screening or testing uptake. When screening uptake was analysed separately, the results were generally similar.

Conclusion

Our findings may have important implications for interventions at community-level (e.g., reducing 'fear-of-judgement', increasing awareness to screening programs and early symptoms) and health-system level (e.g., opportunistic screening).

Perceptions of multi-cancer early detection tests among communities facing barriers to health care

Marginalized racial and ethnic groups and rural and lower income communities experience significant cancer inequities. Blood-based multi-cancer early detection tests (MCEDs) provide a simple and less invasive method to screen for multiple cancers at a single access point and may be an important strategy to reduce cancer inequities. In this qualitative study, we explored barriers and facilitators to MCED adoption among communities facing health care access barriers in Alaska, California, and Oregon. We used reflexive thematic analysis to analyze general barriers to cancer screening, MCED-specific barriers, facilitators of MCED adoption, and MCED communication strategies. We found barriers and facilitators to MCED adoption across 4 levels of the social-ecological model: (1) individual, (2) interpersonal, (3) health care system, and (4) societal. These included adverse psychological impacts, positive perceptions of MCEDs, information and knowledge about cancer screening, the quality of the patient-provider relationship, a lack of health care system trustworthiness, logistical accessibility, patient supports, and financial accessibility. Optimal MCED communication strategies included information spread through the medical environment and the community. These findings underscore the importance of understanding and addressing the multilevel factors that may influence MCED adoption among communities facing health care access barriers to advance health equity.

The ESSAG-trial protocol: A randomized controlled trial evaluating the efficacy of offering a self-sampling kit by the GP to reach women underscreened in the routine cervical cancer screening program

BACKGROUND

In Flanders (Belgium), women not screened for cervical cancer (CC) within the last three years receive an invitation letter from the regional screening organization, the Centre for Cancer Detection (CCD), encouraging them to have a cervical specimen taken by their general practitioner (GP) or gynecologist. However, the coverage for CC screening remains suboptimal (63%). The offer of a self-sampling kit (SSK, for HPV testing) by a GP may trigger participation among women who do not attend regular screening.

METHODS

The ESSAG-trial is a cluster-randomized controlled trial with three arms, each including 1125 women aged 31-64 years, who were not screened for CC in the last 6 years. In arm A, GPs offer a SSK when eligible women consult for any reason. In arm B, women receive a personal GP signed invitation letter including an SSK at their home address. In the control arm, women receive the standard invitation letter from the CCD. The primary outcome is the response rate at three months after inclusion. Secondary outcomes are: screen test positivity; compliance with foreseen follow-up among screen-positives; costs per invited and per screened women; as well as contrasts between trial arms and between socio-demographic categories.

CONCLUSION

The ESSAG-trial will assess the effect of GP-based interventions using SSKs on CC screening participation among hard-to-reach populations. Findings will inform policymakers about feasible strategies on increasing CC screening that may be rolled-out throughout the whole region.

Effectiveness of workplace cancer screening interventions: a systematic review

INTRODUCTION

Cancer cases are rising globally, with a noticeable rise in younger adults. Screening and early detection are effective in decreasing mortality. Workplaces can play a role in promoting cancer screening uptake. This systematic review investigated the effectiveness of workplace breast, lung, colorectal, and cervical cancer screening interventions, and the factors impacting their effectiveness.

METHODOLOGY

Six databases (Embase, Medline, Web of Science, CINAHL, Cochrane Library, Scopus) were searched, and cancer screening promotion and cancer screening uptake was analysed using effect direction plots. Magnitude of effectiveness (i.e., change in knowledge or screening rate) was also evaluated.

RESULTS

In total, 13,426 articles were identified. After screening and applying the eligibility criteria, 21 articles were included in the analysis. A positive effect direction was seen for all workplace cancer screening promotion interventions. Magnitude of effectiveness for cancer screening promotion interventions resulted in a > 30% change in knowledge or screening uptake in 4/7 of breast cancer, in 3/4 of cervical cancer and 1/3 colorectal cancer screening promotion interventions. For workplace cancer screening uptake interventions, a positive effect direction was observed for the majority (18/22). Cancer screening uptake interventions showed a > 30% change in magnitude of screening rate in 4/7 breast cancer, 5/10 colorectal cancer and in 1/5 cervical cancer workplace interventions. No studies for lung cancer were eligible. Factors positively influencing effectiveness included an interest in health and previous healthcare use, while fear of cancer and embarrassment of screening negatively influenced effectiveness.

CONCLUSION

Workplace cancer screening promotion and uptake interventions can effectively improve cancer screening knowledge and increase uptake of screening tests.

Understanding the Preferences and Considerations of the Public Towards Risk-Stratified Screening for Colorectal Cancer: Insights From Think-Aloud Interviews Based on a Discrete Choice Experiment

CONTEXT

Risk stratification has been suggested as a strategy for improving cancer screening. Any changes to existing programmes must be acceptable to the public.

OBJECTIVE

This study aimed to explore the preferences and considerations of individuals relating to the introduction of different risk-based strategies to determine eligibility for colorectal cancer (CRC) screening.

STUDY DESIGN

Participants completed a discrete choice experiment (DCE) within online interviews. Nine conjoint-analysis tasks were created, each with two potential CRC screening programmes. The attributes included personal risk of CRC, screening invitation strategy and impact. Participants chose between programmes while thinking aloud and sharing their thoughts. Transcripts were analysed using codebook thematic analysis.

PARTICIPANTS

Twenty participants based in England aged 40-79 years without previous cancer history or medical expertise.

RESULTS

When choosing between programmes, participants first and primarily looked to prioritise saving lives. The harms associated with screening were viewed as a surprise but also felt by most to be inevitable; the benefits frequently outweighed, therefore, harms were considered less important. Risk stratification using individual characteristics was considered a nuanced approach to healthcare, which tended to be preferred over the age-alone model. Detailed personal risk information could be taken more seriously than non-personalised information to motivate behaviour change. Although it had minimal impact on decision-making, not diverting resources for screening from elsewhere was valued. Individuals who chose not to provide health information were considered irresponsible, while it was important that those with no information to provide should not lose out.

CONCLUSION

Risk-stratified CRC screening is generally aligned with public preferences, with decisions between possible stratification strategies dominated by saving lives. Even if attributes including risk factors, risk stratification strategy and risk communication contributed less to the overall decision to select certain programmes, some levels more clearly fulfilled public values; therefore, all these factors should be taken into consideration when redesigning and communicating CRC screening programmes.

PATIENT OR PUBLIC CONTRIBUTION

The primary data source for this study is interviews with 20 members of the public (current, past or future CRC screening invitees). Two public representatives contributed to planning this study, particularly the DCE.

The association of demographic and socioeconomic variables with cancer screening participation: A national cross-sectional study of three cancer screening programs in Denmark

Objective

To analyze the demographic and socioeconomic determinants of non-participation in cervical, colorectal and breast cancer screening programs in Denmark.

Study design and setting

We conducted a cross-sectional study involving all women aged 53-65 years residing in Denmark on March 31, 2018, utilizing comprehensive individual data from population registries. Logistic regression models were employed to assess associations between demographic and socioeconomic factors and non-participation compared with participating in one, two, and three cancer screening programs, presenting odds ratios (ORs) with 95 % confidence intervals (CIs). Both unadjusted and adjusted models were applied for each level of screening participation.

Results

Significant associations with non-participation in the three cancer screening programs were observed across all demographic and socioeconomic covariates considered. Women with low incomes demonstrated the highest likelihood of non-participation (none vs. three programs attended, OR: 2.95, 95 % CI: 2.82-3.08). Similarly, increased odds of non-participation were noted among immigrants (Western immigrants: OR: 2.08, 95 % CI: 1.96-2.21; non-Western immigrants OR 1.26 95 % CI: 1.20-1.32), women living alone (OR: 2.08, 95 % CI: 2.02-2.14), women outside the labor force (OR: 1.92, 95 % CI: 1.86-1.99), and women with lower educational levels (OR: 1.44, 95 % CI: 1.39-1.50) in the model comparing non-participation to participating in three screening programs. A progressive intensification of the association with non-participation was noted with each incremental increase in screening participation (from one to two to three programs).

Conclusions

Demographic and socioeconomic variables are significantly associated with non-participation in all three Danish cancer screening programs, particularly affecting women from vulnerable demographic and socioeconomic backgrounds. Future research should prioritize strategies to enhance participation within this subgroup, aiming to alleviate social inequities in cancer screening.

Risk-Adapted Breast Screening for Women at Low Predicted Risk of Breast Cancer: An Online Discrete Choice Experiment

BACKGROUND

A risk-stratified breast screening program could offer low-risk women less screening than is currently offered by the National Health Service. The acceptability of this approach may be enhanced if it corresponds to UK women's screening preferences and values.

OBJECTIVES

To elicit and quantify preferences for low-risk screening options.

METHODS

Women aged 40 to 70 y with no history of breast cancer took part in an online discrete choice experiment. We generated 32 hypothetical low-risk screening programs defined by 5 attributes (start age, end age, screening interval, risk of dying from breast cancer, and risk of overdiagnosis), the levels of which were systematically varied between the programs. Respondents were presented with 8 choice sets and asked to choose between 2 screening alternatives or no screening. Preference data were analyzed using conditional logit regression models. The relative importance of attributes and the mean predicted probability of choosing each program were estimated.

RESULTS

Participants (N = 502) preferred all screening programs over no screening. An older starting age of screening, younger end age of screening, longer intervals between screening, and increased risk of dying had a negative impact on support for screening programs (P < 0.01). Although the risk of overdiagnosis was of low relative importance, a decreased risk of this harm had a small positive impact on screening choices. The mean predicted probabilities that risk-adapted screening programs would be supported relative to current guidelines were low (range, 0.18 to 0.52).

CONCLUSIONS

A deintensified screening pathway for women at low risk of breast cancer, especially one that recommends a later screening start age, would run counter to women's breast screening preferences. Further research is needed to enhance the acceptability of offering less screening to those at low risk of breast cancer.

HIGHLIGHTS

Risk-based breast screening may involve the deintensification of screening for women at low risk of breast cancer.Low-risk screening pathways run counter to women's screening preferences and values.Longer screening intervals may be preferable to a later start age.Work is needed to enhance the acceptability of a low-risk screening pathway.

Factors affecting cancer screening perception in Turkish women: the role of health literacy

It is suggested that individuals with limited health literacy have less awareness about cancer and screening methods. However, there is a paucity of evidence regarding the relationship between cancer screening perception and health literacy levels among women. This study investigates the determinants of cancer screening perceptions in Turkish women, with a particular emphasis on the influence of health literacy. Employing a cross-sectional design, the study involved 428 women aged 18-69. Data were collected via online questionnaires. Hierarchical regression analysis was utilized to assess the effects of distinct variables on cancer screening perceptions. Exploratory and confirmatory factor analyses were employed to validate and ensure reliability. The results indicated that the constructed hierarchical regression model explicated around 10% of the variance in cancer screening perceptions. Among the various factors examined, health literacy emerged as the most potent predictor of screening perceptions. Individuals possessing higher health literacy demonstrated more favorable attitudes toward cancer screening. Additionally, age surfaced as another notable determinant, with advanced age correlating positively with awareness and receptiveness to screening. This research reveals the pivotal role of health literacy in shaping how Turkish women perceive cancer screening. While a few factors have an impact, the study highlights the urgent need to elevate health literacy levels to foster heightened awareness and engagement in cancer screening programs. The study's findings offer valuable guidance for devising targeted interventions to address disparities in cancer screening perception and participation, particularly among women in low- to middle-income countries such as Turkey.

Impact of screening participation on modelled mortality benefits of a multi-cancer early detection test by socioeconomic group in England

BACKGROUND

Cancer burden is higher and cancer screening participation is lower among individuals living in more socioeconomically deprived areas of England, contributing to worse health outcomes and shorter life expectancy. Owing to higher multi-cancer early detection (MCED) test sensitivity for poor-prognosis cancers and greater cancer burden in groups experiencing greater deprivation, MCED screening programmes may have greater relative benefits in these groups. We modelled potential differential benefits of MCED screening between deprivation groups in England at different levels of screening participation.

METHODS

We applied the interception multi-cancer screening model to cancer incidence and survival data made available by the National Cancer Registration and Analysis Service in England to estimate reductions in late-stage diagnoses and cancer mortality from an MCED screening programme by deprivation group across 24 cancer types. We assessed the impact of varying the proportion of people who participated in annual screening in each deprivation group on these estimates.

RESULTS

The modelled benefits of an MCED screening programme were substantial: reductions in late-stage diagnoses were 160 and 274 per 100 000 persons in the least and most deprived groups, respectively. Reductions in cancer mortality were 60 and 99 per 100 000 persons in the least and most deprived groups, respectively. Benefits were greatest in the most deprived group at every participation level and were attenuated with lower screening participation.

CONCLUSIONS

For the greatest possible population benefit and to decrease health inequalities, an MCED implementation strategy should focus on enhancing equitable, informed participation, enabling equal participation across all socioeconomic deprivation groups.

Why do people choose not to take part in screening? Qualitative interview study of atrial fibrillation screening nonparticipation

INTRODUCTION

While screening uptake is variable, many individuals feel they 'ought' to participate in screening programmes to aid the detection of conditions amenable to early treatment. Those not taking part in screening are often presented as either hindered by practical or social barriers or personally at fault. Why some people choose not to participate receives less consideration.

METHODS

We explored screening nonparticipation by examining the accounts of participants who chose not to participate in screening offered by a national research trial of atrial fibrillation (AF) screening in England (SAFER: Screening for Atrial Fibrillation with ECG to Reduce stroke). AF is a heart arrhythmia that increases in prevalence with age and increases the risk of stroke. Systematic screening for AF is not a nationally adopted programme within the United Kingdom; it provides a unique opportunity to explore screening nonparticipation outside of the norms and values attached to existing population-based screening programmes. We interviewed people aged over 65 (n = 50) who declined an invitation from SAFER and analysed their accounts thematically.

RESULTS

Beyond practical reasons for nonparticipation, interviewees challenged the utility of identifying and managing AF earlier. Many questioned the benefits of screening at their age. The trial's presentation of the screening as research made it feel voluntary-something they could legitimately decline.

CONCLUSION

Nonparticipants were not resistant to engaging in health-promoting behaviours, uninformed about screening or unsupportive of its potential benefits. Instead, their consideration of the perceived necessity, legitimacy and utility of this screening shaped their decision not to take part.

PATIENT OR PUBLIC CONTRIBUTION

The SAFER programme is guided by four patient and carer representatives. The representatives are embedded within the team (e.g., one is a co-applicant, another sits on the programme steering committee) and by participating in regular meetings advise on all aspects of the design, management and delivery of the programme, including engaging with interpreting and disseminating the findings. For the qualitative workstream, we established a supplementary patient and public involvement group with whom we regularly consult about research design questions.

Health care system and patient-related factors affecting low cancer screening participation in Poland

The level of participation in cancer screening is low in the Polish population. The aim of this study was to assess the opinions of centers providing cancer screening as to the reasons for the low frequency of cancer screening in Poland and possible methods to increase participation. In July 2020 433 centers in Poland carried out breast and/or cervical cancer screening. Of these, 136 centers decided to participate in the study. The study was conducted using an original questionnaire. The questions were addressed to opinion of centers about: reasons for the low frequency of cancer screening in Poland, methods to increase the frequency of cancer screening, pricing and motivating factors for providing cancer screening. Among opinions as to possible reasons for the low frequency of cancer screening in Poland related to the care-system, lack of encouragement from general practitioners, lack of invitations for cancer screening and lack of proper social advertising were most prevalent; whereas among reasons related to patients, a low awareness of cancer screening and fear of cancer diagnosis. The main methods that could potentially increase screening participation are considered to be the inclusion of cancer screening in mandatory periodic employee examinations, more activity by general practitioners, better promotion of screening by central institutions, and sending personal invitations. In conclude some interventions should be carried out to motivate people to break down barriers.

Primary Care Patient Interest in Multi-Cancer Early Detection for Cancer Screening

Multi-cancer early detection (MCED) tests are being developed, but little is known about patient receptivity to their use for cancer screening. The current study assessed patient interest in such testing. Our team conducted a prospective, observational study among primary care patients in a large, urban health system. They were asked to complete a telephone survey that briefly described a new blood test in development to identify multiple types of cancer, but was not currently recommended or covered by insurance. The survey included items to assess respondent background characteristics, perceptions about MCED testing, and interest in having such an MCED test. We also used multivariable analyses to identify factors associated with patient interest in test use. In 2023, we surveyed 159 (32%) of 500 identified patients. Among respondents, 125 (79%) reported a high level of interest in having an MCED test. Interest was not associated with personal background characteristics, but was positively associated with the following expectations: testing would be recommended for cancer screening, be convenient, and be effective in finding early-stage disease (OR = 11.70, 95% CI: 4.02, 34.04, p < 0.001). Research is needed to assess patient interest and actual uptake when detailed information on testing is presented in routine care.

Why is the screening rate in lung cancer still low? A seven-country analysis of the factors affecting adoption

Strong evidence of lung cancer screening's effectiveness in mortality reduction, as demonstrated in the National Lung Screening Trial (NLST) in the US and the Dutch-Belgian Randomized Lung Cancer Screening Trial (NELSON), has prompted countries to implement formal lung cancer screening programs. However, adoption rates remain largely low. This study aims to understand how lung cancer screening programs are currently performing. It also identifies the barriers and enablers contributing to adoption of lung cancer screening across 10 case study countries: Canada, China, Croatia, Japan, Poland, South Korea and the United States. Adoption rates vary significantly across studied countries. We find five main factors impacting adoption: (1) political prioritization of lung cancer (2) financial incentives/cost sharing and hidden ancillary costs (3) infrastructure to support provision of screening services (4) awareness around lung cancer screening and risk factors and (5) cultural views and stigma around lung cancer. Although these factors have application across the countries, the weighting of each factor on driving or hindering adoption varies by country. The five areas set out by this research should be factored into policy making and implementation to maximize effectiveness and outreach of lung cancer screening programs.

The aggregate value of cancer screenings in the United States: full potential value and value considering adherence

BACKGROUND

Although cancer mortality has been decreasing since 1991, many cancers are still not detected until later stages with poorer outcomes. Screening for early-stage cancer can save lives because treatments are generally more effective at earlier than later stages of disease. Evidence of the aggregate benefits of guideline-recommended single-site cancer screenings has been limited. This article assesses the benefits in terms of life-years gained and associated value from major cancer screening technologies in the United States.

METHODS

A mathematical model was built to estimate the aggregate benefits of screenings for breast, colorectal, cervical, and lung cancer over time since the start of US Preventive Services Task Force (USPSTF) recommendations. For each type, the full potential benefits under perfect adherence and the benefits considering reported adherence rates were estimated. The effectiveness of each screening technology was abstracted from published literature on the life-years gained per screened individual. The number of individuals eligible for screening per year was estimated using US Census data matched to the USPSTF recommendations, which changed over time. Adherence rates to screening protocols were based on the National Health Interview Survey results with extrapolation.

RESULTS

Since initial USPSTF recommendations, up to 417 million people were eligible for cancer screening. Assuming perfect adherence to screening recommendations, the life-years gained from screenings are estimated to be 15.5-21.3 million (2.2-4.9, 1.4-3.6, 11.4-12.3, and 0.5 million for breast, colorectal, cervical, and lung cancer, respectively). At reported adherence rates, combined screening has saved 12.2-16.2 million life-years since the introduction of USPSTF recommendations, ~ 75% of potential with perfect adherence. These benefits translate into a value of $8.2-$11.3 trillion at full potential and $6.5-$8.6 trillion considering current adherence. Therefore, single-site screening could have saved an additional 3.2-5.1 million life-years, equating to $1.7-$2.7 trillion, with perfect adherence.

CONCLUSIONS

Although gaps persist between the full potential benefit and benefits considering adherence, existing cancer screening technologies have offered significant value to the US population. Technologies and policy interventions that can improve adherence and/or expand the number of cancer types tested will provide significantly more value and save significantly more patient lives.

Attendance characteristics of the breast and colorectal cancer screening programmes in a highly urbanised region of the Netherlands: a retrospective observational study

OBJECTIVES

Throughout Europe, many countries offer population-based cancer screening programmes (CSPs). In the Netherlands, two implemented CSPs are targeting people of 50 years and older, aiming at breast cancer (BC) and colorectal cancer (CRC). In order for a CSP to be (cost-)effective, high participation rates and outreach to the populations at risk are essential. People living in highly urbanised areas and big cities are known to participate less in CSPs. The aim of this study was to gain further insight into the participation patterns of a screening-eligible population of 50 years and over, living in a highly urbanised region, over a longer time period.

DESIGN

A retrospective observational study.

SETTING

Participation data of the regional screening organisation, linked to the cancer incidence data derived from the Netherlands Cancer Registry, concerning the city of The Hague, between 2005 and 2019. Attendance groups were defined as attenders (attending >50% of the invitations) and non-attenders (attending ≤50% of the invitations), and were mutually compared.

RESULTS

The databases contained 106 377 unique individuals on the BC screening programme (SP) and 73 669 on the CRC-SP. Non-attendance at both CSPs was associated with living in a lower socioeconomic status (SES) neighbourhood and as a counter effect, also associated with a more unfavourable, relatively late-stage, tumour diagnosis. When combining the results of the two CSPs, our results imply high screening adherence over time. Women who did not participate in both CSPs were older, and more often lived in neighbourhoods with a lower SES score.

CONCLUSIONS

Since low screening uptake is one of the factors that contribute to increasing inequalities in cancer survival, future outreach strategies should be focused on engaging specific non-attending subgroups.

Dutch individuals' views of screening for oesophageal cancer: a focus group study

OBJECTIVE

Screening for early oesophageal adenocarcinoma (OAC), including its precursor Barrett's oesophagus (BO), can potentially reduce OAC-related morbidity and mortality. This study explores Dutch at-risk individuals' views of screening an at-risk population for BO/OAC.

DESIGN

We invited 372 individuals with risk factors for OAC from primary care practices, 73 individuals with surveillance experience, and 221 participants of previous studies (BO/OAC screening trial or survey) to participate in focus groups. Transcripts were inductively and thematically analysed by two independent researchers.

RESULTS

A total of 50 individuals (42% with gastro-oesophageal reflux symptoms) of 50-75 years participated. Themes that were raised included: theme 1 'screening intentions' describing participants' motivation to be screened (eg, early diagnosis, potential reassurance, physician recommendation, and knowing someone with cancer) or decline screening (eg, anticipated discomfort or suboptimal accuracy of the test); theme 2 'risk-based eligibility' describing the tension between effectiveness (eg, targeting high-risk individuals) and inclusivity (eg, making screening available for everyone); theme 3 'distributive justice', in which the pressure of a potential new screening programme on healthcare resources was discussed; and theme 4 'information needs' describing the perceived lack of information access and individuals' preference to discuss screening with their general practitioner.

CONCLUSION

Individuals not only expressed high willingness to be screened but also voiced the concern that a new screening programme may pressure limited healthcare resources. If implemented, it is crucial to develop educational materials that meet the public's information needs and explain the test procedures and eligibility criteria while avoiding stigmatising language.

Killing Two Birds with One Stone: Is the COVID-19 Vaccination Campaign an Opportunity to Improve Adherence to Cancer Screening Programmes? The Challenge of a Pilot Project in a Large Local Health Authority in Rome

The COVID-19 pandemic has affected health services worldwide. The suspension of cancer screening programs during the lockdown period, coupled with the other measures taken to limit the SARS-CoV-2 spread, contributed to the idea that cancer preventive interventions are deferrable. In this opinion paper, we present some data on cancer screening coverage in one of the largest Local Health Authorities in Italy in recent years. Within this context, we introduce the benefits of a pilot project in which we took advantage of the great attention on the COVID-19 vaccination campaign to improve screening uptake. In this project, we offered men and women eligible for cancer screening the opportunity to book appointments while waiting to be vaccinated. In addition, trained healthcare personnel were available on-site to discuss any barriers to participation with the attendees. Despite the project having only just started, preliminary results are encouraging, with positive feedback from the attendees. In conclusion, we advocate for the need to adopt a comprehensive approach when it comes to population health, and we use this project as an example to discuss how it is possible to contribute to minimizing the long-term impact of the COVID-19 pandemic with resources already in place.

Perspectives on cancer screening participation in a highly urbanized region: a Q-methodology study in The Hague, the Netherlands

BACKGROUND

The Netherlands hosts, as many other European countries, three population-based cancer screening programmes (CSPs). The overall uptake among these CSPs is high, but has decreased over recent years. Especially in highly urbanized regions the uptake rates tend to fall below the minimal effective rate of 70% set by the World Health Organization. Understanding the reasons underlying the decision of citizens to partake in a CPS are essential in order to optimize the current screening participation rates. The aim of this study was to explore the various perspectives concerning cancer screening among inhabitants of The Hague, a highly urbanized region of the Netherlands.

METHODS

A Q-methodology study was conducted to provide insight in the prevailing perspectives on partaking in CSPs. All respondents were inhabitants of the city of The Hague, the Netherlands. In an online application they ranked a set of 31 statements, based on the current available literature and clustered by the Integrated Change model, into a 9-column forced ranking grid according to level of agreement, followed by a short survey. Respondents were asked to participate in a subsequent interview to explain their ranking. By-person factor analysis was used to identify distinct perspectives, which were interpreted using data from the rankings and interviews.

RESULTS

Three distinct perspectives were identified: 1). "Positive about participation", 2). "Thoughtful about participation", and 3). "Fear drives participation". These perspectives provide insight into how potential respondents, living in an urbanized region in the Netherlands, decide upon partaking in CSPs.

CONCLUSIONS

Since CSPs will only be effective when participation rates are sufficiently high, it is essential to have insight into the different perspectives among potential respondents concerning partaking in a CSP. This study adds new insights concerning these perspectives and suggests several ideas for future optimization of the CSPs.

What are common barriers and helpful solutions to colorectal cancer screening? A cross-sectional survey to develop intervention content for a planning support tool

OBJECTIVE

Colorectal screening using faecal immunochemical tests (FITs) can save lives if the people invited participate. In Scotland, most people intend to complete a FIT but this is not reflected in uptake rates. Planning interventions can bridge this intention-behaviour gap. To develop a tool supporting people willing to do colorectal screening with planning to complete a FIT, this study aimed to identify frequently experienced barriers and solutions to these barriers.

DESIGN

This is a cross-sectional study.

SETTING

Participants were recruited through the Scottish Bowel Screening Programme to complete a mailed questionnaire.

PARTICIPANTS

The study included 2387 participants who had completed a FIT (mean age 65 years, 40% female) and 359 participants who had not completed a FIT but were inclined to do so (mean age 63 years, 39% female).

OUTCOME MEASURES

The questionnaire assessed frequency of endorsement of colorectal screening barriers and solutions.

RESULTS

Participants who had not completed a FIT endorsed significantly more barriers than those who had completed a FIT, when demographic, health and behavioural covariates were held constant (F(1,2053)=13.40, p<0.001, partial η2=0.01). Participants who completed a FIT endorsed significantly more solutions than those who did not (U=301 585.50, z=-3.21, p<0.001, r=0.06). This difference became insignificant when covariates were controlled. Participants agreed on the most common barriers and solutions regardless of screening history. Barriers included procrastination, forgetting, fear of the test result, screening anxiety, disgust and low self-efficacy. Solutions included hand-washing, doing the FIT in private, reading the FIT instructions, benefit of early detection, feelings of responsibility, high self-efficacy and seeing oneself as a person who looks after one's health.

CONCLUSION

This survey identified six barriers and seven solutions as key content to include in the development of a planning tool for colorectal screening using the FIT. Participatory research is required to codesign an engaging and accessible planning tool.

Postal reminder with reduced burden of clinic information seeking for equitable participation in general health check-ups: A randomized controlled trial

High participation rate and low inequality in participation are key to the program success of general health check-ups in Japan. This study examined the effectiveness of a postal reminder including nearest clinic information, compared to the standard postal reminder including details of all local clinics, on participation rate and income-based participation rate in general health checks. This was a single-blind, two-arm, prospective, randomized controlled study conducted at the Fukuoka Branch of Japan Health Insurance Association. Dependents (family members) of insured persons aged 40-69 years were randomly assigned (1:1) to the intervention group that received a tailored postal reminder intervention (showing information on the nearest clinic from each participant's address) or to the control group that received an original template postal reminder (containing just the URL of the website listing all available clinics). Allocation was concealed from participants and service providers of general health check-up. The primary outcome was participation in general health check-ups within 1 month of intervention. Between February 1 and February 10, 2017, 21,017 were randomly assigned to the intervention (n = 10,474) or control (n = 10,543) group. The participation rate in the intervention group was higher than control group (3.2% vs. 2.1%; OR: 1.55, 95% CI: 1.31-1.85, P < 0.001). The intervention effect was estimated to decrease as the income category increased (P for interaction = 0.037). Tailored postal reminders with information on the nearest clinic were able to improve the overall participation rate and reduce income-based inequality in participation for general health check-ups in Japan.
