Intravesical Thio-tepa in the Immediate Postoperative Period in Patients with Recurrent Transitional Cell Carcinoma of the Bladder

Abstract
Recurrent transitional cell carcinoma was treated with prophylactic intravesical thio-tepa [triethylenethiophosphoramide] in 22 cases. Group 1 patients were treated with 30 mg twice daily for the first 3 days postoperatively. Group 2 patients were given additional treatment at increasing intervals indefinitely. Before therapy control patients averaged 1 recurrence every 9.5 mo. Group 1 patients averaged 1 recurrence per 33 mo. Group 2 patients averaged 1 recurrence per 41 mo. Leukopenia occurred in 2 patients. Thio-tepa can be given safely in the immediate postoperative period and is effective in decreasing the recurrence rate of superficial bladder tumors.
