Treatment of Carcinoma In Situ With Intravesical Bacillus Calmette-Guerin Without Maintenance

Abstract

A single course of BCG is remarkably effective for primary carcinoma in situ and carcinoma in situ associated with Ta transitional cell carcinoma but is suboptimal in patients with carcinoma in situ associated with T1 transitional cell carcinoma. Better outcomes in each of the 3 groups may have occurred with maintenance BCG.
