Abstract
Fifty-five patients with superficial transitional cell carcinoma of the bladder were assigned by rotation to 1 of 3 treatment categories. Group 1 patients were treated by transurethral resection alone, group 2 by transurethral resection followed by topical thiotepa and group 3 by transurethral resection followed by orally administered BCG. Recurrent bladder tumors developed subsequently in 80% of the patients in group 1, 42.9% in group 2 and 6.2% in group 3.
