[Prostate cancer in Isère and Tarn (France) between 1985 and 1995: evolution of therapeutic indications]

The objective is to describe the evolution of therapeutic practices of prostate carcinoma in the departements of Tarn and Isère in France for the 1985-1995 period. This retrospective study is based on patient folders for whom a prostate carcinoma has been diagnosed between 1985 and 1995. A sample of 871 patients have been included after randomisation stratified on the year and the department of the diagnostic in the files of the cancer registries of Tarn and Isère. Therapeutic practices of the prostate cancer have significantly evolved between 1985 and 1989. The rate of radical prostatectomies increased from 1986 whereas the rate of radiotherapy remained stable. This evolution has been made to the detriment of non curative treatments with the decrease of the rate of hormonotherapies. This is due to the important development of diagnostic technics which led to an earlier diagnostic of these cancers; but, the evolution of therapeutic technics and particularly of the radical prostatectomy allowed the evolution of indications for the treatment of this cancer, with the increase of the rate of radical prostatectomies and the decrease of the rate of radiotherapies at the same stage of disease evolution. For 1990 to 1995, there was no major evolution. Some indications are discussed in this disease touching old man, with a slow evolution.
