[Clinical studies of patients with bladder cancers].
A clinical survey was performed on 185 cases of primary bladder cancer treated at our Department of Urology, between January, 1985 and December, 1989. Clinicopathological profiles of patients and survival rates according to these profiles were investigated. The patients were between 29 and 95 years old. The male to female ratio was 3.1 to 1. The cumulative survival rate after the first treatment was 73.3% and 71.5% at 3 and 5 years, respectively. Histologically, 17 cases were diagnosed as transitional cell carcinoma G1, 69 cases as G2 and 69 cases as G3. 5 cases were diagnosed as stage pTis, 6 cases as pTa, 41 cases as pT1, 15 cases as pT2, 9 cases as pT3a, 14 cases as pT3b and 6 cases as pT4. Stage, grade, size and type of tumors reflected the prognosis well. Significant differences were observed between the survival rates of the patients with grade G2 and grade G3, and the patients with stage T1 and stage T2. Although low-grade low-stage tumors recurred in 44% of the patients. The pathological stage showed a good relation to the grade. In particular, none of the G1 bladder tumors had muscle invasion in our series.
