Sex differences in muscle-invasive bladder cancers: a study of a French regional population.

OBJECTIVES: Although men have a higher risk of developing a bladder cancer, women appear to have a poorer prognosis and a more advanced stage at diagnosis. We performed a retrospective population-based study on muscle invasive bladder cancer (MIBC) using data from a cancer registry in a French department to compare overall and specific survival data according to sex. MATERIAL AND METHODS: We included all patients living in the department of Hérault and diagnosed with MIBC between January 1, 2017 and December 12, 2019. Univariable and multivariable analyses were performed on all variables of interest. RESULTS: We included 124 women and 432 men. There was no significant difference in age or stage at diagnosis according to sex. Squamous cell carcinomas were more common in women (p<0.001). Cystectomy was more frequent in men than in women (50.7% vs 35.4%) (p=0.0039). By multivariable analysis, the independent factors for being treated by cystectomy were sex (p=0.004), age (p<0.001) and stage (p<0.001). Forty-seven percent of women received no treatment or palliative treatment. Overall mortality was 79% in women and 63.2% in men (p<0.001). The median specific survival was 10.8 months in women and 32.7 months in men (p<0.0001). By multivariable analysis, the independent risk factors for mortality were female sex (p=0.047), cT4 stage (p=0.005) and absence of cystectomy (p<0.001). CONCLUSIONS: Our study shows that women are less often treated with cystectomy and have worse prognosis than men. The reasons for this gender difference are multifactorial.

OBJECTIVES: The Hérault Tumor Registry (RTH) is a general registry qualified by the national committee of registries since 1987. The objective of this study is to present the evolution of the epidemiology of bladder cancer (stage≥T1) in the Hérault department based on data collected by the RTH over a period from 1987 to 2019. MATERIAL AND METHODS: We analyzed trends in bladder cancer incidence in Hérault between 1987 and 2019 by sex, age, and stage, as well as mortality trends between 1987 and 2017. For the years 2018-2019, which are the last two years validated by the registry, we described relative frequencies, sex ratio, mean and median age at diagnosis, cumulative risk, stages at diagnosis, pathology data, and primary treatments. Observed and net survival data are analyzed for those diagnosed between 01/01/2000 and 12/31/2015 with a point date of 06/30/2018. RESULTS: In 2018-2019, bladder cancer was the 7th most common cancer in Hérault (5th in men and 12th in women) with an incidence sex ratio of 3.9 men to one woman. The mean age at diagnosis was 75.3 years for men and 77.8 years for women. The probability of having bladder cancer before the age of 75 years was 1.68% for a man (1/59) and 0.34% for a woman (1/295). Urothelial carcinomas accounted for 90.7% of cancers. Between 1987 and 2019, bladder cancer incidence TSMs (worldwide standardized rates) decreased by 0.8% per year in men and remained stable in women. Mortality TSMs between 1987 and 2017 followed the same trends with a decrease of 2.2% per year in men and stability in women. For the 3304 bladder cancers diagnosed between 01/01/2000 and 12/31/2015, the observed 5-year survival was 38% (34% in women and 38% in men). CONCLUSIONS: Bladder cancer incidence and mortality rates have decreased slightly in men but remain stable in women in the Hérault. Registries collect only a limited number of variables for each patient. In 2018 the Hérault Registry Specialized in Onco-Urology (RHESOU) was created, to have comprehensive data.

[Adhesion of urologists to the recommendations of the French Urological Association Cancer Committee (CCAFU) in the imaging work-up of localized prostate cancer]. / L'adhésion des urologues aux recommandations du comité de cancérologie de l'association Française d'urologie (CCAFU) dans le bilan d'imagerie du cancer localisé de la prostate.

OBJECTIVES: The literature review shows a low adhesion of urologists to the recommendations of learned societies in the imaging work-up of localized prostate cancer (CaP), especially for low and intermediate risks of the D'Amico classification. We analyzed the adhesion of urologists in the Hérault region (France) to the CCAFU 2016/2018, 2018/2020 recommendations. MATERIAL AND METHODS: From the Hérault Onco Urology Registry (RHESOU) database, we identified localized CaP diagnosed between 01/01/2017 and 31/12/2019, and then classified them into 3 distinct risk groups according to the D'Amico classification. We compared the imaging workup performed by each patient to the CCAFU 2016/2018, 2018/2020 recommendations, according to the risk group. RESULTS: Of the 2,049 localized CaPs included in our study, 591 belonged to the low-risk group, 1059 to the intermediate-risk group, and 399 to the high-risk group. In the low-risk group 45.2% of the cases did not follow the CCAFU 2016/2018, 2018/2020 recommendations in the imaging workup, 77.3% in the intermediate-risk group and 80.9% in the high-risk group. For our entire study, 1,408 patients (68.7%) had an imaging workup that did not follow the CCAFU recommendations. CONCLUSION: Our results show a low adhesion of urologists to the CCAFU recommendations in the imaging assessment of localized CaP. The causes of this non-adhesion are multifactorial and difficult to analyze.
