- Introduction. - European Randomized Study of Screening for Prostate Cancer (ERSPC) mortality results were reported for 7 European countries (excluding France) and showed a significant reduction in Prostate cancer (PCa) mortality. As those results have not been part of the global ERSPC results, it is of interest to report PCa mortality at a median follow-up of 9 years for French section of ERSPC. Material and methods. - Two administrative departments were involved in the study. Only men after randomization in the screening group were invited by mail to be screened by PSA testing with two rounds at 4-6 year intervals. Biopsy was recommended if PSA> = 3.0 ng/mL. No information other that the French Association of Urology recommandations on the use of PSA was offered to the control group (own decision of physicians and patients). Follow up was based on cancer registry database. Contamination defined as the receipt of PSA testing in control arm was measured. Poisson regression models were used to estimate the Rate Ratio (RR) of PCa mortality and incidence in the screening vs. control arm. Results. - Starting from 2003, 80,696 men aged 55-69 years were included. The percentage of men in the screening arm with at least one PSA test (compliance) was 31%. Compared to the control arm. PCa incidence increased by 10% in the screening arm (RR = 1.10; 95% CI = [1.04-1.16], P=0.001), but PCa mortality did not differ (0.222 and 0.215 deaths/1000 person-years; RR= 1.03[0.75-1.42], P=0.9). Discussion. Limitations include low participation rate. PSA testing in the control arm was observed in 32% of men (contamination). Conclusions. - Contamination in control group led to no effect of PSA-based screening on prostate cancer mortality at 9 years follow-up. Level of evidence. 3. (C) 2020 Elsevier Masson SAS.

- BACKGROUND: Cancer occurrence among older people with intellectual disability (ID) is poorly documented, so we investigated the frequency and distribution of cancer in older people with ID compared with the general population.METHOD: People with ID who were ≥55years old and alive at the end of 2012 (n = 7936; ID cohort) were identified through a national register of people with ID who received social services in Sweden to optimise the individual's opportunity for good living conditions in daily life. An equally large reference cohort from the general population (gPop cohort) was matched by year of birth and sex. Cancer diagnoses registered in inpatient and outpatient specialist care were collected for 2002-2012 from the ID cohort and compared with diagnoses in the gPop cohort.RESULTS: A lower total cancer frequency was observed in the ID cohort, which contained 555 cancers, compared with 877 cancers in the gPop cohort [odds ratio (OR): 0.63; 95% confidence interval (CI): 0.57-0.70]. Women accounted for 60% of cancers in the ID cohort. Breast and gynaecological organ cancers had similar or slightly lower frequencies in the ID cohort than in the general population, with breast OR of 0.95, uterine corpus OR of 1.00 and ovary OR of 0.73. Surprisingly, cancer frequency of the digestive organs (OR: 0.67), including the colon (OR: 0.82), was lower than in the general population. Cancers of the prostate (OR: 0.25), urinary tract (OR: 0.42) and lung were less frequent than in the general population.CONCLUSIONS: Cancer was diagnosed less frequently in the ID cohort than in the gPop cohort. However, cancers of the breast and colon-rectum remain frequent in people with ID and therefore warrant prevention policies, monitoring and screening similar to those of the general population.
