[Prostate cancer screening in France: Results from the EDIFICE surveys]. / Dépistage du cancer de la prostate en France : résultats des enquêtes EDIFICE.

INTRODUCTION: Prostate cancer (PCa) is the most common cancer amongst men in 2018 in Europe. The issue of PCa screening in the general population has been debated following the publication of international European (ERSPC) and North American (PLCO) studies. There is currently no organised PCa screening. The objective of this analysis was to evaluate the practice of PCa screening in the French population with no history of cancer between 2005 and 2016. METHODS: Since 2005, the EDIFICE surveys have focused on the knowledge and behaviour of French people with regard to cancer screening. The practice of screening was evaluated according to the answer to the question: "Have you ever done PCa screening?" Responses were analysed according to age, socio-professional category and level of social precariousness. RESULTS: After a strong increase between 2005 and 2008 (from 36% to 49%, P≤0.01), a significant decrease in the reported PCa screening rate was observed between 2014 (49%) and 2016 (42%; P=0.02). This decrease was mainly reflected in the socially advantaged categories and in the youngest age group (50-54 years). Screening practices remain the same in older men. CONCLUSION: The perception of the effectiveness of PCa screening could explain the changes of behavior in the French population. This decrease in participation in PCa screening requires monitoring to avoid a general loss of confidence in cancer screening. LEVEL OF EVIDENCE: 3.

Prostate cancer screening: contrasting trends.

PURPOSE: Our previously published data showed rapidly increasing rates of prostate cancer screening in men aged 50-74, which rose from 36% in 2005 to 48% in 2008. Based on men's reported intentions at that time, this was expected to rise to 70% in 2011. Here we report the actual rate of prostate cancer screening. METHOD: Three nationwide observational telephone surveys (EDIFICE opinion polls) were conducted in 2005, 2008, and 2011. The overall target was a representative sample of > 1,500 individuals living in France and aged 40-75 years, including 481 men aged 50-74 years. RESULTS: Within this male population, the rate of screening reported remained stable between 2008 and 2011 (48 and 49%, respectively). However, comparison of privileged versus disadvantaged populations showed significant differences, with a relative decrease in screening among those of higher socioprofessional status (p = 0.03) and from higher-income groups (p = 0.02). For households with a monthly income above 2,500€, the screening rate decreased from 61% in 2008 to 51% in 2011 (p = 0.05), while for those with an income below 2,500€, it increased from 36% in 2008 to 44 % in 2011 (p = 0.18). CONCLUSION: A plateau or even a reduction in prostate cancer screening is currently being observed; this is possibly due to progressive recognition among the population at large of the controversy surrounding prostate cancer screening, whereas this speculation was formerly limited to health-care professionals. After previously being more likely to undergo prostate cancer screening, it is the younger, wealthier populations that are currently showing the most noteworthy step backwards.

Melanoma risk-takers: fathers and sons.

OBJECTIVES: The incidence of skin cancers, melanoma in particular, is increasing rapidly. Consequently, specific recommendations for sun-protection measures now exist. This survey set out to assess the compliance of the general population with these guidelines. METHODS: The French nationwide observational survey, EDIFICE Melanoma, was conducted (28 September to 20 October 2011) through phone interviews of a representative sample of 1502 subjects aged ≥ 18 years, using the quota method. Sun-protection was defined as frequent or systematic use of clothes or sunscreen. The group of individuals who declared exposure to the sun (N = 1172) was subdivided: risk-takers (N = 442), and those who used sun protection (N = 730). RESULTS: Risk-takers were significantly more often male (62% vs. 44%, P < 0.01), had a lower level of education (40% vs. 26%, P < 0.01), lower incomes (2587 euros vs. 2948 euros/month) and were more often smokers (42% vs. 31%, P < 0.01). In contrast, age, marital status and use of sunbeds were not significantly different between the two groups. Interestingly, risk-takers had less risk factors for melanoma. However, they were less well-informed about high-risk exposure and optimal use of sunscreen. Sun-protection measures for their children were less stringent than those of the group who used sun protection: systematic/frequent use of sunglasses (42% vs. 59%, P < 0.01), systematic use of sunscreen (77% vs. 86%, P < 0.01), and frequent renewal (69% vs. 82%, P < 0.01), high sun protection factors (SPF) (46% vs. 56%, P < 0.01), use of clothing (84% vs. 92%, P < 0.01) and hats (88% vs. 94%, P < 0.01). CONCLUSIONS: Risk-takers are characterized by a lesser understanding of sun-protection measures and behaviours. Their children benefit less from protective measures than those of people who use sun protection themselves. Improved understanding may well improve behaviours; one can therefore legitimately predict a considerable impact on parents' attitude to their own protection and that of their children.

Colorectal liver metastases are more often super wild type. Toward treatment based on metastatic site genotyping?

Recent data showed that metastatic colorectal (mCRC) tumors exhibiting extended RAS-BRAF mutations were resistant to anti-epidermal growth factor receptor (EGFR) monoclonal antibodies, making these drugs suitable for the so-called "super" wild-type (WT) patients only. This study aimed to compare the extended RAS-BRAF mutation frequency and characteristics according to location of tumor sampling. All consecutive mCRC specimens (N = 1659) referred to our institution from January 2008 till June 2014 were included in the analysis. Tumor genotyping (first for KRAS exon 2, then for BRAF exon 15, and later for KRAS exons 2, 3, and 4 and NRAS exons 2, 3, and 4) was performed with high-resolution melting analysis or allelic discrimination. The factors predicting for the presence of mutation were explored using multivariate binary logistic regression. Overall, the prevalence of KRAS exon 2 was 36.8%, and it was lower in liver metastases (N = 138/490; 28.2%) in comparison with primary tumors (N = 442/1086; 40.7%), lung metastases (16/32; 50%), or other metastatic sites (15/51; 29.4%; P < 0.0001). Similarly, in the 1428 samples analyzed, BRAF mutations were less often found in liver metastases (N = 9/396; 2.3%) as compared to primary tumors (N = 79/959; 8.2%), lung metastases (N = 2/29; 6.9%), or other metastatic locations (N = 2/44; 4.5%; P < 0.0002). Overall occurrence of extended RAS mutation was 51.7%. Of the 503 samples tested, the prevalence of extended RAS-BRAF mutations was twice as low in liver metastases (N = 53/151; 34.2 %) as compared to primary tumors (N = 191/322; 59.3%, P < 0.0001). Univariate analysis identified age ≤65 years, male gender, and liver localization as predictors of super WT status. At multivariate analysis, only liver metastases were retained (RR 2.85 [95% CI 1.91-4.30]). Colorectal liver metastases are twice as likely to exhibit a super WT genotype as compared to other tumor locations independently from other factors. This molecular feature has the potential to influence therapeutic strategy in mCRC patients.

Prognostic impact of microsatellite instability in colorectal cancer patients treated with adjuvant FOLFOX.

BACKGROUND: Colorectal cancer (CRC) patients whose tumours have microsatellite instability (MSI) do not benefit from adjuvant 5-fluorouracil. However, the predictive value of MSI is not known for FOLFOX, now recommended in adjuvant setting. PATIENTS AND METHODS: MSI phenotype was assessed by the pentaplex method. Three-year relapse and disease-free survival (DFS) of patients treated for CRC with FOLFOX 4 in an adjuvant setting were compared according to MSI phenotype. RESULTS: A total of 105 patients (19 MSI, 86 microsatellite stable, MSS) were included. Stage II patients more frequently exhibited MSI (58%) than MSS (21%); (p=0.002). Patients with MSI relapsed significantly less than those with MSS (10.5% vs. 35.0%; p=0.04). DFS was similar for MSI and MSS (p=0.1). In univariate analysis, stage (p=0.0006) and MSI status (p=0.017) were significant predictors of DFS. CONCLUSION: MSI status was associated with significantly fewer relapses and a better prognosis. FOLFOX4 did not alter survival of patients with MSI and can be administered to them.

[Single-center cohort study of elderly patients with surgically removed colorectal cancers]. / Patients agés opérés et pris en charge pour un cancer colorectal: etude d'une cohorte monocentrique.

Incidence of colorectal cancers (CRCs) increases with age. The surgical and medical management of elderly patients needs to be improved. Until recently, these patients were not included into controlled clinical trials. Between 2004 and 2007, 88 patients (median age 79) had surgery for CRC in our hospital. In half the cases, patients had an emergency surgery (40/88). Twenty patients had dementia, with no relationships between dementia and emergency surgery (50% vs. 45% for patients without dementia), nor between dementia and median length of hospital stay (16 days vs. 22 days). In metastatic setting (20 patients), chemotherapy was omitted in 10 cases, usually patients with dementia (5 patients; p = 0.002) Standard therapy was hardly applicable because many patients were frail. In the future, usefulness of participation to the staffs of a geriatrist will be assessed prospectively.

[Description of erlotinib-related skin effects management in France. Results of the PRECEDE study]. / Prise en charge des effets dermatologiques sous erlotinib. Résultats de l'étude PRECEDE.

INTRODUCTION: Dermatological effects are among the most frequent side-effects in patients receiving erlotinib (Tarceva). However, there no official recommendations on the preventive or curative management of those erlotinib-related skin effects (ERSE). The "Prise En Charge des Effets Dermatologiques sous Erlotinib" (PRECEDE) study was designed to study how ERSE are being managed in France. MATERIAL AND METHODS: The PRECEDE study is an observational retrospective study which included every nonsmall cell lung cancer patients treated with erlotinib in seven cancer centers in France from January 2005 to December 2007. Data related to preventive or curative treatment of ERSE were collected from the medical files of the patients. RESULTS: Two hundred and thirty-four patients were included; 48.7% of them had been delivered information on the potential occurrence of ERSE and 15.8% of those 234 patients had had prescription of drugs to be taken in case of ERSE, while 65.0% presented with ERSE which resolved in the majority of cases (86.2% of the patients), either spontaneously or under treatment. In the 85 patients in whom treatment was successful, 178 drug prescriptions comprising 35 different drugs were recorded. CONCLUSION: ERSE are frequent but regress in most cases, spontaneously or under treatment. However, there is still a wide variety of drugs used. This demonstrates that there is a need for recommendations on the management of ERSE in order to prevent and treat this erlotinib-related effect.

[Edifice program: analysis of screening exam practices for cancer in France]. / Le programme Edifice : analyse des pratiques de dépistage du cancer en France.

INTRODUCTION: The practices of screening and the parameters influencing these practices are not well known in France. The objectives of the Edifice study were to analyze a large cohort of patients and doctors in order to further characterize these parameters. PATIENTS AND METHODS: The study was performed by the Institute TNS Healthcare-SOFRES, and included 2 parallel studies: 1) on 1 609 healthy persons representative of the global French population and aged 40 to 75 years (N = 1 509), with an over representation of patients aged 50 to 74 years living in the 22 pilot French departments pilots; 2) on 600 generalist practitioners. Data were collected and analyzed by the expert panel... RESULTS: Ninety-three, 25, 36 and 6% of the patients in the general population declared to have performed at least one a screening exam for breast, colon, prostate, and lung carcinoma respectively. Seventy, 20, 60 and 4% of GP declare to propose systematically to a 40-75-year-old patient a screening test for breast, colon, prostate, or lung cancer. For breast cancer screening the adhesion of the GP is independent of the date of implementation of a general screening in their own regions, while for colorectal screening, 34 and 20% of the patients living in the pilot versus other departments were screened. Overall, prostate cancer screening is recommended by the GP panel for 77.1% of patients aged 50 to 75 years. CONCLUSIONS: This study shows a good adhesion of screening procedures for GP and patients, shows that screening is improved by general screening policy in colorectal cancer, but that prostate cancer screening practices exceed what is recommended according to evidence based medicine.
