Ninety-two cases of advanced bladder tumor treated at the University of Tokyo and branch hospital from January 1977 to December 1992 were analyzed. The advanced bladder tumor was defined as that of higher than pT2 (according to the General Rule for Clinical and Pathological Studies on Bladder Cancer) or that with distant metastases. The following variants were evaluated, the therapeutic methods, the histological type, grade, stage, type of infiltration. The evidence of lymphatic infiltration, vessel infiltration, and lymph node metastases were also reviewed. The survival rate was calculated using Kaplan-Meier's method. In the cases with lymph node metastases, the survival rate was significantly lower than in the cases without metastases (p < 0.01), while no other factors affected the survival rate.
