[A clinical study of superficial bladder cancer with grade 3 components].
A retrospective study was done on 33 patients treated for superficial bladder cancer, pTa and pT1, with grade 3 components between 1986 and 1995. All patients had undergone transurethral resection of the tumor (TUR-Bt), which was followed by total cystectomy in 7 patients. Three patients died of pulmonary diseases or heart attack and 6 patients subsequently died of bladder cancer. The 2-year and 5-year disease-specific survival rates of these patients were 83% and 75%, respectively, and the mean duration of follow-up was 50 months. Comparison of the disease-specific survival rates for several factors revealed that the configuration and size of the tumors were significantly predictable factors for prognosis. In well-selected patients with grade 3 superficial bladder cancer, bladder preservation seems to be possible by TUR with or without adjuvant therapies. Hence further studies on a larger series are needed to elucidate more feasible and reliable prognostic factors to avoid unnecessary cystectomy and improve the quality of life of the patients.
