BACKGROUND: In this multicenter study, the yearly national evaluation of @entity5 of the kidney was out by the Oncology Committee of the French Association of Urology. METHODS: During the period from April 1, 1992, to March 31, 1994, 1486 @entity1 from 54 centers were included in this study. For each @entity1 , an individual chart was created, in which age, gender, discovery circumstances of the @entity5 , radiologic and biologic workup, treatment, @entity2802 classification, and histologic features of the @entity5 were recorded. RESULTS: The mean @entity1 age was 62.1 years, and the male-to-female ratio was 2:1. Forty percent of the @entity5 were discovered accidentally. A radical nephrectomy was performed in 93% of the cases, and in 7% of the cases, conservative management was adopted. Medical treatment was chosen in 5% of the cases. The @entity1 distribution according to classification was as follows: @entity2558 = 8%, pT2 = 53%, pT3a = 21%, and pT3b = 18%. Lymph node involvement was observed in 9% and visceral @entity3 in 6% of the cases. The incidental @entity5 were intracapsular in 80% of the cases. From the histologic point of view, the majority of the @entity5 were @entity16488 (66%). The mean @entity5 maximum dimension was 6.4 +/- 3.5 cm; it was significantly greater in symptomatic @entity1 and @entity1 with poor prognostic indicators (involvement of the adrenal gland, inferior vena cava, and/or lymph nodes and visceral @entity3 ). Adrenal gland involvement or inferior vena cava involvement were each observed in 4% of the cases. Fourteen percent of the @entity1 had multicentric @entity5 spread, which was influenced by neither the @entity5 size nor the cell type. The nuclear grade was established in 66% of the cases and was significantly correlated with involvement of the perirenal fat and the lymph nodes. CONCLUSIONS: This study allowed the authors to centralize one-fifth of all new cases of @entity1358 in France in the course of a year. It enabled them to evaluate precisely the current epidemiologic profile of this disease among those @entity1 .
