Abstract
OBJECTIVES: To determine the success of additional bacillus Calmette-Guérin (BCG) therapy for transitional cell carcinoma recurring after a complete response (CR) to the initial treatment course of BCG. METHODS: All patients treated with BCG with a minimum follow-up of 5 years were reviewed to identify complete responders who subsequently recurred and received additional BCG therapy. The duration of initial response and the incidence and duration of a second CR were recorded. RESULTS: Of 11 patients with an initial CR to a 6-week course of BCG, 9 (82%) achieved a second CR and 5 of the 9 (42%) maintained tumor-free status beyond 5 years of follow-up (median 87 months, range 64 to 110). Patients who again recurred after the second CR did not benefit from further BCG therapy. CONCLUSIONS: A repeat course of BCG is a reasonable option of therapy for transitional cell carcinoma that has recurred after a CR to a prior course of BCG. Careful monitoring by cytology, cystoscopy, and biopsy is mandatory to direct nonresponders to prompt alternative therapy and to ensure continued disease-free status among responders.
