Experience with intravesical bacillus Calmette-Guèrin therapy of superficial bladder tumors

Between March, 1978, and July, 1981, 86 patients with polychronotopic superficial papillary bladder tumors and concurrent carcinoma in situ were randomized to receive either transurethral resection alone (43) or TUR plus BCG (43). The results indicate that BCG is not only active in preventing recurrences of new tumors but also effective for the diffuse, flat carcinoma in situ.
