[Treatment outcome of 288 cases of renal cell carcinoma].
The clinical outcome was analyzed on 288 patients with renal cell carcinoma who were admitted to the Niigata Cancer Center Hospital during the 33 years from 1961 to 1993; 254 patients had had nephrectomy and 244 of them had undergone curable operations. The survival rate was calculated by the Kaplan-Meier method. The 3-, 5- and 10-year survival rates by all causes of death in all 288 patients were 64.8, 55.9 and 36.4%, respectively. According to the stage based on the general rules for clinical and pathological studies on renal cell carcinoma (The 2nd Edition), the 5-year survival rate was 89.5, 78.7, 51.1 and 13.7% for stages I (n = 31), II (n = 128), III (n = 38) and IV (n = 83), respectively. The 5-year survival rate for the patients (n = 88) from 1961 to 1985 was 40.9%, while the rate for the patients (n = 200) from 1986 to 1993 was 64.3%. This improvement of survival rate for the patients after 1986 was brought by the increase of the stage I or II cases and by the improvement of the survival in the stage III cases after 1986. The 5-year disease-specific survival rate for the patients over 50 years old was 55.5%, while the rate for the patients under 50 years old was 83.6%. Female, low pT, low grade and small tumor size were proven to be favourable prognostic factors in renal cell carcinoma.
