Cancer Screening In France Research Articles

Participation in breast cancer screening and its influence on other cancer screening invitations: study in women aged 56 years old in four French departments.

Today, women 50 years of age are offered three types of cancer screening in France. However, participation is not optimal. The aim was to describe (1) participation in organised breast cancer screening (OS) of women aged 56 years old, and the influence of this participation on colorectal and cervical cancer screening, (2) the reasons for non-participation in breast cancer OS, and (3) the reasons for screening before age 50. A questionnaire was sent to 56-year-old women in four French departments to identify their participation behaviour in three breast cancer OS invitations and their reasons for non-participation. Three groups were determined according to the number of participations in breast cancer OS (3, 1-2 and 0). We described the quantitative responses and grouped the qualitative responses thematically. A total of 4634 women responded to the questionnaire. Seventy-six percent had undergone all three breast cancer OS, 16% irregular and 7% non-participant. Among women who irregularly perform breast cancer OS, 50.5% also irregularly perform colorectal cancer OS. Women who participated in all three invitations for the breast cancer OS performed more smear tests than women in the other groups. Many of the irregular participants or non-participants underwent opportunistic screening, often initiated before the age of 50. The reasons for non-participation in breast cancer OS were mainly medical or participation in opportunistic screening. There is no fundamental opposition to participation in breast cancer screening. However, it remains of the utmost importance that women should be better informed about OS and its benefits.

Coverage rate of opportunistic and organised breast cancer screening in France: Department-level estimation

ObjectiveIn France, the national breast cancer screening programme (NBCSP), targeting women aged 50–74 years was rolled out nationwide in 2004. It aims at reducing breast cancer mortality. In addition to the NBCSP, the use of opportunistic screening is permitted in France. The objective of this study is to estimate both opportunistic use and overall coverage rates of breast cancer screening, among women 40–84 years of age, in France. MethodsThe French medico-administrative health data system (SNDS) was used to identify women performing an opportunistic or organised mammography screening in France in 2016–2017. ResultsThe two-yearly opportunistic mammography screening is 18 % among women aged 40–84; it is 11 % among women aged 50–74, i.e., the target age range for organised screening, 36 % among women aged 40–49 and 13 % among women aged 75–84. The overall two-yearly screening coverage is 48 % for all women aged 40–84; it is 60 % among women aged 50–74, 36 % among women 40–49 and 16 % for those aged 75–84. Geographical variations in screening are lessened when the two screening strategies are considered, as they balance each other. ConclusionAlthough coverage in the NBCSP is around 50 % in France, more than one third of the women make use of opportunistic screening within and outside the target age range. Organized screening appears to improve equity of access to mammography screening service. The lack of data on opportunistic screening practices hinders the evaluation of French screening practices as a whole.

Effectiveness of Artificial Intelligence-Assisted Decision-making to Improve Vulnerable Women's Participation in Cervical Cancer Screening in France: Protocol for a Cluster Randomized Controlled Trial (AppDate-You).

BackgroundThe French organized population-based cervical cancer screening (CCS) program transitioned from a cytology-based to a human papillomavirus (HPV)–based screening strategy in August 2020. HPV testing is offered every 5 years, starting at the age of 30 years. In the new program, women are invited to undergo an HPV test at a gynecologist’s, primary care physician’s, or midwife’s office, a private clinic or health center, family planning center, or hospital. HPV self-sampling (HPVss) was also made available as an additional approach. However, French studies reported that less than 20% of noncompliant women performed vaginal self-sampling when a kit was sent to their home. Women with lower income and educational levels participate less in CCS. Lack of information about the disease and the benefits of CCS were reported as one of the major barriers among noncompliant women. This barrier could be addressed by overcoming disparities in HPV- and cervical cancer–related knowledge and perceptions about CCS.ObjectiveThis study aimed to assess the effectiveness of a chatbot-based decision aid to improve women’s participation in the HPVss detection-based CCS care pathway.MethodsAppDate-You is a 2-arm cluster randomized controlled trial (cRCT) nested within the French organized CCS program. Eligible women are those aged 30-65 years who have not been screened for CC for more than 4 years and live in the disadvantaged clusters in the Occitanie Region, France. In total, 32 clusters will be allocated to the intervention and control arms, 16 in each arm (approximately 4000 women). Eligible women living in randomly selected disadvantaged clusters will be identified using the Regional Cancer Screening Coordinating Centre of Occitanie (CRCDC-OC) database. Women in the experimental group will receive screening reminder letters and HPVss kits, combined with access to a chatbot-based decision aid tailored to women with lower education attainment. Women in the control group will receive the reminder letters and HPVss kits (standard of care). The CRCDC-OC database will be used to check trial progress and assess the intervention’s impact. The trial has 2 primary outcomes: (1) the proportion of screening participation within 12 months among women recalled for CCS and (2) the proportion of HPVss-positive women who are “well-managed” as stipulated in the French guidelines.ResultsTo date, the AppDate-You study group is preparing and developing the chatbot-based decision aid (intervention). The cRCT will be conducted once the decision aid has been completed and validated. Recruitment of women is expected to begin in January 2023.ConclusionsThis study is the first to evaluate the impact of a chatbot-based decision aid to promote the CCS program and increase its performance. The study results will inform policy makers and health professionals as well as the research community.Trial RegistrationClinicalTrials.gov NCT05286034; https://clinicaltrials.gov/ct2/show/NCT05286034International Registered Report Identifier (IRRID)PRR1-10.2196/39288

Interest of individual breast cancer screening by mammography in women aged over 75 years

Retrospective study of a continuous monocentric series of women over 75 having undergone surgery for breast cancer. The following variables were studied: addressing after screening or not, age at diagnosis, UICC stage and therapeutic measures (surgery by lumpectomy or mastectomy, lymph node dissection, adjuvant treatment with chemotherapy, radiotherapy or hormone therapy). 185 women aged 82.8 ± 5.2 years [extreme ages 75 to 95] were included in the study. 136 (73.5%) breast cancers were discovered after palpation and 49 (26.5%) after screening mammography. The distribution by stage was: I - 38.8%, II - 39.5%, III - 15.1% and stage IV - 7%. 164 (87.7%), patients received surgical treatment: 115 lumpectomies (61.2%) and 49 mastectomies (26.5%). 51 (27.6%) patients underwent lymph node dissection. The distribution of adjuvant treatments was: chemotherapy 21.1%, radiotherapy 68.6%, or hormone therapy (79.5%), sometimes combined. Women not screened are older than women screened (84 ± 5.3 versus 79.5 ± 3.6 years; p < 0.0001). Cancers are diagnosed at a more advanced stage in non-screened patients compared to screened patients (p < 0.0001). While there is a higher proportion of stage I among screened patients (75.5%), stage II is the most frequent in women not screened (47%). Stage I and II are the majority in the latter (72%). In multivariate analysis with adjustment for age, screening made it possible to make a diagnosis at a less advanced stage (stage I-II vs II-IV: OR = 5.593; 95% CI [1.575–19.866]; p = 0.0078) and to have conservative surgery more often (lumpectomy vs mastectomy: OR = 2.645; 95% CI [1.079–6.493]; p = 0.0333) without more recourse to surgery (OR = 1.856 95% CI [0.207–16.612]; p = 0.58). After adjusting for age and stage, screening was no longer a determining factor in the choice of type of surgery (OR = 1.934; 95% CI [0.753–4.975]; p = 0.170). At the age when organized breast cancer screening in France stopped, there was a decrease in survival, a diagnosis at a higher stage and an increase in co-morbidities. Our study shows a change in management with heavier treatment, more complications and a greater loss of autonomy without screening. This pleads for a continuation beyond 75 years of the practice of mammography screening for breast cancer in elderly women.

Participation in Opportunistic and Organised Breast Cancer Screening in France: Department-Level Estimation

Participation in Opportunistic and Organised Breast Cancer Screening in France: Department-Level Estimation

Feasibility Study to Assess the Impact of a Lifestyle Intervention during Colorectal Cancer Screening in France.

Current evidence suggests that 30–50% of cancers are attributable to established lifestyle risk factors. Cancer-screening has been identified as an opportunity for delivering advice on lifestyle behaviour change for cancer prevention. This study aimed to evaluate the feasibility and acceptance of promoting advice on the latest evidence-based lifestyle recommendations for cancer prevention at the time of colorectal cancer screening at two hospitals in Lyon, France. This feasibility study included 49 patients (20 men and 29 women) who were invited for colonoscopy. Patients received a leaflet with lifestyle recommendations for cancer prevention, accompanied with a logbook to plan and monitor their behavioural changes. Feedback from patients, hospital staff, and researchers was received via evaluation questionnaires (n = 26) completed after testing the educational material for at least two weeks and via two focus group discussions (n = 7 and n = 9 respectively) organized at the end of the study. All interviewed patients were interested in lowering their cancer risk, and the majority felt ready to change their lifestyle (88%), although most did not know how to decrease their risk of cancer (61%). All patients found the educational material easy to understand and sufficiently attractive and 50% of the patients reported having achieved at least one of the healthy behaviours recommended within the two weeks following the intervention. All hospital staff and almost all patients (92%) involved found that the screening program and the visits planned for colonoscopy was an appropriate moment to provide them with the educational material. This feasibility study has shown that the content, paper-based format, and time of delivery of the intervention were adequate. Health professionals seem to be willing to provide lifestyle recommendations, and patients appear interested in receiving advice for lowering their cancer risk during screening visits.

Updated evidence-based recommendations for cervical cancer screening in France.

IntroductionA national organized cytology-based cervical cancer screening program was launched in 2018 and rollout is ongoing. Concomitantly, the High Authority for Health (HAS) recently assessed new evidence on primary HPV testing to update screening recommendations.MethodsThe HAS commissioned systematic reviews and meta-analyses to evaluate the effectiveness of primary HPV screening; accuracy of HPV testing on self-samples; effectiveness of self-sampling to reach underscreened women; and triage strategies to manage HPV-positive women. Recommendations developed by the HAS were reviewed by a multidisciplinary group.ResultsCompared with cytology screening, HPV screening is more sensitive to detect precancers but less specific. In women aged ≥30, if the test is negative, HPV screening greatly reduces the risk of developing precancer and cancer for at least 5 years. HPV testing, using validated PCR-based assays, is as sensitive and slightly less specific on self-samples than on clinician-taken samples. Self-sampling is more effective to reach underscreened women than sending invitations to have a specimen taken by a clinician. Two-time triage strategies ensure a sufficiently high risk if triage-positive to justify referral and low risk if triage-negative allowing release to routine screening.ConclusionsThe HAS recommends three-yearly cytology screening for women aged 25–29 and HPV screening for those aged 30–65 with an extension of the screening interval to 5 years if the HPV test is negative. Self-sampling should be offered to underscreened women aged ≥30. HPV-positive women should be triaged with cytology. Those with abnormal cytology should be referred for colposcopy and those with normal cytology re-tested for HPV 12 months later. Recommendations for implementation of HPV-based screening in the organized program are provided.

Which communication strategies can improve interventions aimed at tackling social inequalities in organized cancer screening in France?

Interventions to increase participation in cancer screening programs have been developed and evaluated by our research team. The results observed provide an opportunity to consider which methods of communication should be encouraged to improve those interventions. The objective of this commentary is to recommend communication strategies which should be adopted to efficiently reach and support disadvantaged individuals to engage in cancer screening, as a healthy behaviour.

Screening for cancers of the cervix and vagina for women exposed to diethylstilbestrol (DES) in utero

ObjectivesIn total, 80,000 women were exposed to diethylstilbestrol (DES) in utero in France (DES daughters) between 1950 and 1977. After having been dominated by the management of infertility and pregnancy accidents, monitoring must adapt to the increased risk of cancer of the cervix and vagina: doubling of the frequency of severe dysplasia and a risk of late clear-cell adenocarcinoma (CCA). Two recent changes in cervical cancer screening in France, the introduction of HPV tests in first-line screening and organized screening, should consider the particular situation of DES daughters. We aimed to assess the compliance of DES daughters with previous recommendations and propose specific screening practices in the new context. MethodA non-profit organization carried out a questionnaire survey of its members who were exposed to DES in utero. ResultsAmong the 570 participants, 64 % had annual PAP tests, 25 % within the last three years, and 11 % more than three years before or never. The reasons for "dropout" were: 1) ignorance of the recommendations by practitioners (38 %) or patients (30 %), 2) fatigue (32 %) or apprehension of the exams (14 %), and 3) difficult access to care: time to get an appointment (26 %), difficulty in finding a doctor (28 %), or cost (6 %). ConclusionThese results concern women who were sufficiently aware of the issue to be a member of an association. They are encouraging but show a need to improve the dissemination of information to all “DES daughters” and health professionals. Patient associations can play a growing role in this “rare disease” by addressing patients and healthcare professionals. We propose that screening for these women include an annual screen of not only the cervix, but also the vagina, and that it continues beyond 65 years of age and after hysterectomy, with cytological examination, because ACC is unrelated to HPV.

Factors associated with compliance to cervical cancer screening in France: The EDIFICE 6 survey

IntroductionA nationwide cervical cancer (CC) screening program was implemented in France in 2018. Asymptomatic women are invited for a cytological test once every 3 years (age, 25–29 years), and an HPV test every 5 years (age, 30–65 years). We investigated the characteristics of women who are resistant to CC screening. MethodsSince 2005, the EDIFICE survey program has assessed attitudes toward cancer screening in France. The 6th edition (2017) included 12,046 representative women (age, 18–69 years). Social vulnerability was assessed using the EPICES score. Multivariate stepwise logistic regression analysis identified factors correlated with nonuptake of CC screening. ResultsQuestionnaires from 4499 women (age, 25–65 years) with no history of cancer were analyzed; 88% (N = 3960) reported at least one test in their lifetime, and 73% (N = 3262) did the test in the previous 3 years. Compared to ever-screened women, never-screened women were younger (38 ± 11 yrs. vs 44 ± 12 yrs., P < 0.05), and more likely to be single (48% vs 20%, P < 0.05) and/or socially vulnerable (59% vs 38%, P < 0.05). In multivariate analysis, items significantly (P < 0.05) associated with never screening included living alone (OR = 2.26, 95% CI [1.85–2.75]) and social vulnerability (OR = 1.95 [1.59–2.40]). Women who were not compliant with recommendations were more likely to be older (mean age, 49.2 yrs. vs. 43.2 yrs), living alone (single, widowed or divorced, 40% vs. 30%, P < 0.05), and/or socially vulnerable (55% vs. 35%, P < 0.05; OR = 1.78, 95% CI [1.49–2.12]). ConclusionThis analysis identified several factors associated with never screening and under-screening. Effective prevention messages should specifically target these populations.

Cervical cancer screening coverage, management of squamous intraepithelial lesions and related costs in France.

Until 2018, cervical cancer screening in France was an unorganized individual screening, with the exception of some pilot programs in some territories. We aimed to assess, before the implementation of organized cervical cancer screening and human papillomavirus (HPV) nonavalent vaccine introduction in the vaccination schedule in 2018, (i) the individual cervical cancer screening coverage, (ii) the management of squamous intraepithelial lesions (SIL) and (iii) the related costs. We used the Système National des Données de Santé (SNDS) (Echantillon Généraliste de Bénéficiaires [EGB] and Programme de Médicalisation des systèmes d’information [PMSI]) to assess the cervical screening coverage rate in France between January 1st, 2012 and December 31st, 2014, and to describe diagnostic investigations and therapeutic management of SIL in 2013. After extrapolation to the general population, a total of 10,847,814 women underwent at least one smear test over the 3-year study period, corresponding to a coverage rate of 52.4% of the women aged 25 to 64 included. In 2013, 126,095 women underwent HPV test, 327,444 women underwent colposcopy, and 9,653 underwent endocervical curettage; 31,863 had conization and 12,162 had laser ablation. Besides, 34,067 women experienced hospital stays related to management of SIL; 25,368 (74.5%) had high-grade lesions (HSIL) and 7,388 (21.7%) low-grade lesions (LSIL). Conization was the most frequent in-hospital therapeutic procedure: 89.5% (22,704) of women with an in-hospital procedure for HSIL and 64.7% (4,781) for LSIL. Mean cost of smear test, colposcopy and HPV tests were around 50€. Total cost for hospital stays in 2013 was estimated at M41€, or a mean cost of 1,211€ per woman; 76% were due to stays with HSIL. This study highlights the low coverage rate of individual cervical cancer screening and a high burden related to SIL management.

Evaluation of additional benefits of HPV vaccination to cervical cancer screening in France

Abstract Background The National Cancer Institute (INCa) undertook the evaluation of the expected impact of HPV vaccination in the context of the recent marketing of nonavalent vaccine (Gardasil®9) and the implementation of organized screening (OS) of cervical cancer (CC) in France. Methods The study is based on a microsimulation model that replicates the natural history of CC. A cohort of 14-year-old women is generated and followed until death. Others HPV-infection related diseases (condyloma, anal cancer, penile cancer and oropharynx cancer) are not modelled. Different strategies were compared with the current vaccination coverage rate (VCR) of 21.4% (2017): impact of increased VCR alone and increased VCR combined with correction of inequalities (CI). Results are presented according to two hypotheses for the duration of protection offered by the vaccine (limited to 20 years and lifelong) and according to two hypotheses for price of the vaccine (French price and average European prices). Results The incremental cost-effectiveness ratio (ICER) was less than 15 000 euros per QALY (quality-adjusted life year) in all the assessed strategies. For each 14-year-old women cohort, 85% VCR with CI would prevent at least: 2 546 conations, 2 347 precancerous lesions CIN 2 / 3 diagnosed, 377 CCs, 139 deaths per CC (20 years vaccine protection). Scenarios based on increasing VCR with CI are the most cost-effective. Conclusions The study quantifies the increased risk of CC-related outcomes associated with current sub-optimal VCR and the possible investment to implement actions in order to improve the efficiency of the current strategies and tackle health inequalities (communication campaign, actions toward underserved women). Key messages Improving HPV vaccination uptake is a cost-effective measure, even considering only the cervical cancer prevention. Including health inequalities participation in modeling is crucial as underserved women are both less vaccinated and screened.

Towards equity in organised cancer screening: the case of cervical cancer screening in France

BackgroundThe French national cancer institute (INCa) conducted a series of studies to assist decision-making in view of the implementation of organised cervical cancer screening that will be launched in 2018. The programme will concern all women aged 25–65 and targeted interventions will be developed for underscreened populations. This is an evolution from an equality-based approach to a step-by-step strategy of equity aiming to tackle health cancer inequalities that are avoidable and represents unfair differences. Here we present the work of the expert-group in ethics drafted by INCa to review the ethical issues prior to the programme implementation.DiscussionWe discuss the value of such a strategy and presents reflections with regard to issues of stigmatization, respect for individual freedom and autonomy. Indeed, the balance has to be found between the search for beneficence and the potential occurrence of perverse effects, which should be considered with particular attention.ConclusionMoving toward an equity-oriented policy under a strategy of proportionate universalism faces a number of challenges, thus an overview of ethics and social sciences must be an integral part of the process.

Place actuelle du dépistage du cancer du poumon en France et dans le monde

Lung cancer is a good candidate for screening. The NLST trial demonstrated that annual low-dose CT-scan in a high risk population of smokers reduced specific mortality by 20% and overall mortality by 6.7%.Current position of lung cancer screening in France and worldwide is presented in this review.In France, the topic is dominated by french heath autorithies skepticism. Worldwide there are deep differences: US and Canada have iplemented lung cancer screening in routine while Europe still waiting for NELSON results and pooled analysis of european trials.In practice, interval between two low-dose CT-scan ay be delayed at 2 years (but no more), in particular among individuals who have a negative CT-scan. Biomarkers and risk-prediction scores are clearly very interesting perpectives but need prospective validation.

Abstract P6-08-07: Decline in compliance to breast cancer screening in France: Results of the 5th EDIFICE survey

Abstract Background The EDIFICE surveys have been conducted since 2005 to provide a better understanding of the participation of the French population in cancer screening programs. The breast cancer (BC) screening program is nowadays widely implemented throughout the target female population: women aged 50-74 years are invited for a mammogram once every two years. We analyzed the behavior of women over time (between 2005 and 2016) regarding BC screening according to age-group, socioprofessional categories (SPC) and social vulnerability. Methods The fifth nationwide observational survey, EDIFICE 5, was conducted by phone interviews using the quota method. A representative sample of 1299 subjects aged 50-74 years with no history of cancer was interviewed between November 22 and December 7, 2016. Interviewees (women aged 50-74 yrs; N=657) were asked about their uptake of BC screening, and the date of the last examination to determine the follow-up rate. Demographic data on social characteristics and SPC were also collected to determine the level of social vulnerability (validated EPICES score). Results Compliance with BC screening (a mammogram within the past 2 years) decreased significantly from 81% in 2014 to 75% in 2016 (P=0.02). From 2014, a significant impact of age was observed (P=0.02 in 2014 and 2016). In 2016, and for the first time, a significant and disturbing decrease in follow-up rate was recorded among younger women (age 50-54 yrs: 88% in 2014 vs 74% in 2016, P=0.01). SPC had no effect on compliance with screening. However, since 2008, fluctuations have been observed among unemployed individuals (U), with a significant decline in compliance in 2016 (U: 81% in 2014 vs 73% in 2016, P=0.03). In 2016, social vulnerability was seen as a factor that negatively impacts on compliance with BC screening (P≤0.01), but not in 2011 or 2014. We also observed a significant overall decrease in 2016 among both vulnerable (76% in 2014 vs 65% in 2016; P=0.04) and non-vulnerable populations (85% in 2014 vs 79% in 2016, P=0.04), highlighting a general loss of confidence. Conclusion For the first time since 2005, compliance with BC screening dropped significantly in France in 2016. A significant overall decline was observed regardless of social vulnerability status. Disturbing significant decreases were observed among the younger age-group (women aged 50-54 yrs) of the target population of the organized program, and among unemployed women. Although organized programs have been shown to ensure equitable access to cancer screening, this achievement remains precarious and requires regular monitoring.

Low participation in organized colorectal cancer screening in France: underlying ethical issues.

International studies have shown a significant reduction in colorectal cancer (CRC) mortality following the implementation of organized screening programs, given a sufficient participation rate and adequate follow-up. The French national CRC screening program has been generalized since 2008 and targets 18 million men and women aged 50-74 years. Despite broad recommendations, the participation rate remains low (29.8%), questioning the efficiency of the program. A panel of experts was appointed by the French National Cancer Institute to critically examine the place of autonomy and efficiency in CRC screening and propose recommendations. In this paper, we explore the ethical significance of a public health intervention that falls short of its objectives owing to low take-up by the population targeted. First, we analyze the reasons for the low CRC screening participation. Second, we examine the models that can be proposed for public health actions, reconciling respect for the individual and the collective good. Our expert panel explored possible ways to enhance take-up of CRC screening within the bounds of individual autonomy, adapting awareness campaigns, and new educational approaches that take into account knowledge and analysis of sociocultural hurdles. Although public health actions must be universal, target actions should nonetheless be developed for nonparticipating population subgroups.

1409P - Cervical cancer screening in France: recent change in behaviors

Background: Cervical cancer (CC) is the fourth most common cancer in women in France. Human papillomavirus vaccination and screening are complementary secondary prevention measures against CC. Screening by conventional Pap smear is recommended every three years for women aged 25-65y. Methods: The EDIFICE nationwide observational surveys assess population attitudes to cancer screening in general. Representative samples of the French population aged 50-75 years are interviewed by phone using the quota method. Although the French CC screening program covers all women aged 26-65y, the present analysis pertains to a subpopulation aged 50-65y (N = 356 in 2014 and N = 460 in 2016). Interviewees, with no personal history of cancer, were asked if they had ever had a smear test during a gynecological exam. The date of the last test was noted. Data analysis focused on age group, socioprofessional categories (SPC) and social vulnerability (defined by the EPICE score). Results: In 2016, 94% of interviewees reported at least one lifetime smear test vs. 99% in 2014 (P<0.01). In line with current interval recommendations, 74% in 2016 and 75% in 2014 (P=0.81) had had the latest test done in the past three years. Younger age groups were significantly more likely to be compliant with the recommendations in 2014 (P<0.01) though not in 2016 (P=0.18). SPC also had a significant impact on compliance rates in 2016 (P=0.01) but not in 2014. Vulnerable women were less likely to be screened at least once in their lifetime; this trend was non-significant in 2014 (98% vs 100% in non-vulnerable, P=0.14) but significant in 2016 (89% vs. 97%, P<0.01). Vulnerable women were also significantly less likely to be compliant with the recommendations (64% vs 81%, P<0.01 in 2014; 63% vs.79%, P=0.01 in 2016). Conclusions: Between 2014 and 2016, participation in CC screening decreased and compliance rates stagnated. Compliance with screening recommendations was negatively affected by the following: unemployment, low SPC or classification among vulnerable populations. Additional analysis will further investigate these findings, which highlight the need for generalized population-based screening programs and targeted actions for non-participants, as advocated earlier this year by the French National Cancer Institute (INCa).

Patient navigation to reduce social inequalities in colorectal cancer screening participation: A cluster randomized controlled trial.

Despite free colorectal cancer screening in France, participation remains low and low socioeconomic status is associated with a low participation. Our aim was to assess the effect of a screening navigation program on participation and the reduction in social inequalities in a national-level organized mass screening program for colorectal cancer by fecal-occult blood test (FOBT). A multicenter (3 French departments) cluster randomized controlled trial was conducted over two years. The cluster was a small geographical unit stratified according to a deprivation index and the place of residence. A total of 14,556 subjects (72 clusters) were included in the control arm where the FOBT program involved the usual postal reminders, and 14,373 subjects (66 clusters) were included in the intervention arm. Intervention concerned only non-attended subjects with a phone number available defined as the navigable population. A screening navigator was added to the usual screening organization to identify and eliminate barriers to CRC screening with personalized contact. The participation rate by strata increased in the intervention arm. The increase was greater in affluent strata than in deprived ones. Multivariate analyses demonstrated that the intervention mainly with phone navigation increased individual participation (OR=1.19 [1.10, 1.29]) in the navigable population. For such interventions to reduce social inequalities in a country with a national level organized mass screening program, they should first be administered to deprived populations, in accordance with the principle of proportionate universalism.

Contextual determinants of participation in cervical cancer screening in France, 2010

BackgroundSome contextual factors associated with participation in cervical cancer screening are reported in the literature, but few studies have examined their combined effect. Our objective was to assess the role of contextual characteristics, separately and in combination, in participation in cervical cancer screening in France. MethodsMarginal Poisson regression models – taking into account the correlation between women in a given commune – were conducted using data from the Baromètre Santé 2010 survey. The characteristics of the commune of residence of the women studied were the potential spatial accessibility to general practitioners (GP) and gynecologists, the agglomeration category, and the socioeconomic level. ResultsThe analyses were performed in 3380 women, 88.2% of whom were up to date with their cervical cancer screening. Once the individual characteristics were taken into account, the screening participation rate was similar in all the communes, with the exception of those with poor access to a gynecologist and good access to a GP, where the rate was 6% lower (95%CI: 0.5–11%) than in the communes with good access to both GP and gynecologist. The same association with accessibility was observed in small agglomerations. Compared to women living in the more advantaged communes, the screening participation rate was 8% (2–12%) lower in those living in the more disadvantaged ones, except when accessibility to both types of physician was high. DiscussionWe observed an association between potential spatial accessibility to care in women’s residential communities and their cervical cancer screening practices, in particular in small agglomerations, rural communes, and more disadvantaged communes.
