[Renal cell adenocarcinomas. Report of 64 cases].

The authors report 64 renal cell carcinomas observed in 64 patients over a period of 14 years (1982-1995). The mean age was 58 years (range: 20 to 80 years). Male involvement was observed in 34 cases (53%). The clinical symptoms were nonspecific, consisting of haematuria (26 cases), back pain (33 cases) and tumour (8 cases). Twenty patients presented with paraneoplastic syndromes and 4 presented with metastases. The tumour was an incidental finding in 6 cases. Fifty two patients were treated by radical nephrectomy and two by partial nephrectomy. The tumour was associated with venous involvement in 2 cases, lymphatic involvement in 4 cases and distant metastases in 2 cases. The overall 5-year survival was 37% with a poor prognosis in the case of lymph node involvement or metastases and in the case of secondary local recurrence (4 cases) or distant metastases (2 cases).
