    Abstract:
    Total cystectomy was performed on 95 patients with primary urinary bladder cancer between 1973 and 1983. Histopathological and prognostic studies were reviewed according to the general rules for clinical and pathological studies on bladder cancer. The cancer histological type were transitional cell carcinoma in 87 cases, squamous cell carcinoma in 5 cases, adenocarcinoma in 2 cases, and undifferentiated carcinoma in 1 case. The overall 5-year actuarial survival rate was 36.0%. As for the growth pattern of the bladder cancer, the 5-year survival rates for the patients with papillary non-invasive type (PNT), papillary invasive type (PIT), and non-papillary invasive type (NIT) were 100%, 25.8% and 34.8% respectively. As for the stage, the 5-year survival rates for the patients with pTa, pT1, pT2, pT3a, pT3b, and pT4 were 81.8%, 64.7%, 40.1%, 30.5%, 22.6% and 6.7% respectively. Of 87 patients with transitional cell carcinoma, the 5-year survival rates for the patients with grade 1, grade 2 and grade 3 were 100%, 43.0% and 32.1% respectively. Intramural lymphatic invasion and vascular invasion and intramural histopathological mode of spread were significant indicators of prognosis.
