[A clinicopathological study on patients with bladder cancer treated with cystectomy].
A clinical and histopathological investigation was made on 170 patients with bladder cancer who underwent total cystectomy at our institutions between 1982 and 1986. The overall 5-year survival rates of patients with pTis + pTa, pT1, pT2, pT3, pT3b and pT4 were 100, 71.8, 60.7, 39.2, 31.4 and 0% respectively, those of patients with G1, G2 and G3 were 100%, 67.6%, 35.7% respectively. As for histopathological growth and spread pattern (INF), intramural lymphatic invasion (ly) and venous invasion (v), INF beta, INF gamma, ly2, v (+) showed the worst prognosis. These histopathological factors were considered to be closely correlated to each other. Studies on these histopathological factors are very important in planning the subsequent therapy.
