[A clinical study of 92 cases of renal cell carcinoma--statistical analysis of prognosis according to the new TNM classification].
A clinico-statistical study was made on 92 patients with renal cell carcinoma who visited us from January 1978 to November 1988. The results were as follows: 1. Seventy-eight patients were treated by radical nephrectomy, two patients by partial nephrectomy, and three patients were treated at other hospitals initially. Nine patients were underwent only conservative therapy. 3. Overall 1, 3, 5, and 10-year survival rates by Kaplan-Meier method were 81.8%, 58.0%, 55.3%, and 50.2%, respectively. 3. The 3-year survival rates according to clinical T-stage were 71.3% for 56 patients in T2, 66.8% for 16 patients in T3a, and 24.1% for 16 patients in T3b. A significant difference existed between patients in T3a and patients in T3b. It appears that the new TNM classification system is more accurate for prognosis of patients in stage T3 than that currently in use.
