Prognostic factors for progression of superficial bladder cancer

Abstract

To clarify prognostic factors for progression of superficial transitional cell carcinoma of the bladder (Ta, T1 and G1, G2), 159 patients, treated by transurethral resection from 1975 to 1988, were analysed concerning clinical findings, laboratory data, endoscopic findings and histopathological findings of the tumor. Histopathological findings included ABH blood group isoantigen (ABH) and Thomsen-Friedenreich antigen (T-ag) as well as other result. Twenty two cases in the series showed progression; 10 with up-grading and up-staging, 12 with either one of them. Advanced age, positive urinary cytology, multiple or broad base tumor, G2 or T1 tumor, negative ABH and abnormal T-ag were closely associated with progression. By multivariate analysis of these factors, ABH, stage of the tumor, T-ag and form were shown to be important prognostic factors in this order. ABH and T-ag were not correlated with other cliniocopathological factors in predicting tumor progression. Therefore we concluded that ABH and T-ag were much important for prediction concerning potential for progression of the superficial bladder cancer. © 1992, THE JAPANESE UROLOGICAL ASSOCIATION.
