A description of radical prostatectomy (PR) practice in the general population in France has never been reported. The objective of this study was to analyse RP practice in France, and its determinants and geographical variations based on the CCAFU-Francim survey on prostate cancer (PC) diagnosed in 1995.
175 PR were performed on the sample of 798 patients selected at random from the cases of PC identified in 1995 by four cancer registries (Bas-Rhin, Calvados, Isère and Tarn). Analysis was based on tumour characteristics, diagnostic methods and histopathological results. Multivariate analysis by logistic regression taking into account age, PSA and clinical stage studied variations between departments and types of urology practice (private or public).
The mean age of the patients at the time of the diagnosis was 65.3 years (46-76). The median PSA was 18.3 ng/ml (1-184). The diagnosis was made by biopsies (91%) which were systematized in 74% of cases or by transurethral resection (7%). The clinical stage was T1 (22.3%), T2 (64%), T3 (8.6%), N+ (0.611) and unknown (4.5%). The pathological stage was pT2N0 (46.3%), pT3N0 (40%), pT4N0 (1.7%), pTxN0 (8.6%) and unknown (3.4%). Adjuvant treatment (radiotherapy: 13.7%, endocrine therapy: 13.7% or both: 31%) was performed in 54 patients (31%). Multivariate analysis showed that the adjusted probability to be treated by RP was 3 times higher in one department compared to others and 2.6 times higher in the private sector.
This study of RP practice in the general population shows a concordance with the 1995 recommendations, but it also shows practice variations according to the region and the type of practice, reflecting different schools of thought and medical education within the same country.
