Intracavitary Bacillus Calmette-guerin in the Treatment of Superficial Bladder Tumors

Abstract
Patients with recurrent superficial bladder tumors were treated by vesical and intradermal administration of BCG. The pattern of recurrence in 9 patients was altered favorably. Although the findings are still preliminary they appear to hold promise of a new therapeutic approach to the treatment of a group of neoplasms for which effective therapy is still lacking.
