description

Objectives. To evaluate a selected population of 50 consecutive patients with primary T1, G3 bladder transitional cell carcinoma in the absence of carcinoma in situ (Tis) treated with a bladder-sparing approach. Methods. Between January 1983 and December 1992, all patients were treated by transurethral resection (TUR) plus adjuvant intravesical chemotherapy over 1 year. In most cases, doxorubicin, epirubicin, and mitomycin were used alone or in combination. Results. At a mean follow-up period of 52 months (range, 18 to 126), 16 of 50 patients (32%) showed a recurrent superficial tumor. The recurrent lesion was of Stage T1 in 11 (22%) cases, but was a T1, G3 tumor only in 5 cases (10%). In 2 additional patients (4%) a Tis developed during the observation period after TUR. The mean interval between TUR and first recurrence was 14.6 months (range, 3 to 38). At a mean time of 17 months after the initial TUR, 3 patients (6%) underwent a radical cystectomy due to a progression in T category and 3 additional patients (6%) developed distant metastases at a mean time of 23 months after TUR. In brief, 84% of the patients are alive and tumor-free. Five patients (10%) died of bladder cancer with a mean follow-up of 52 months. Conclusions. If no concomitant Tis exists, a conservative approach is a legitimate option as an initial treatment of patients with primary T1, G3 bladder tumors.
