Treatment of Residual, Non-infiltrating Bladder Cancer with Bacillus Calmette-guerin

Abstract
Systemic and intracavitary administrations of BCG were used to treat patients with incompletely resected transitional cell carcinoma of the bladder. The treatment induced tumor regression in 59% of the patients. This trial confirms previous reports indicating that non-specific active immunotherapy is useful in the prevention of superficial recurrences and in the treatment of residual tumors that have not infiltrated.
