Segmental resection in the management of bladder carcinoma

Segmental resection for bladder carcinoma was performed on 144 patients at our medical center between 1945 and 1971. Of these 144 cases 101 had sufficient documentation to provide meaningful data for a retrospective study. The 5-year survival rates for patients with invasive bladder carcinoma, expressed as a function of the stage of disease, were stage A--79 per cent, stage B1--80 per cent, stage B2--45 per cent and stage C--6 per cent. The combined survival rates for patients with stages O, A and B1 tumors and for those with B2 and C disease were 83 and 27 per cent, respectively. A significant observation was that of the patients with stages O, A and B1 disease only 7 per cent had a history of antecedent tumor. In contrast, 59 per cent of the patients with stage B2 and C disease had antecedent tumor.
