Between 13.8% and 27% of all superficial bladder cancers are represented by pT1G3 neoplasm. In the Department of Urology of Policlinico S. Marco-Zingonia, between February 1988 and June 1994, we treated 22 patients suffering for pT1G3 bladder tumor. TUR-B has demonstrated to be a good approach for treatment of superficial bladder cancer, with low morbility; on the opposite side, we have to underline the high rate of recurrence and of progression of the urothelium disease. Now a day our best approach for the treatment of pT1G3 bladder tumor is represented by radical cystectomy supplied by chemotherapy.
