INTRAVESICAL INSTILLATION OF EPIRUBICIN, BACILLUS CALMETTE-GUERIN AND BACILLUS CALMETTE-GUERIN PLUS ISONIAZID FOR INTERMEDIATE AND HIGH RISK TA, T1 PAPILLARY CARCINOMA OF THE BLADDER: A EUROPEAN ORGANIZATION FOR RESEARCH AND TREATMENT OF CANCER GENITO-URINARY GROUP RANDOMIZED PHASE III TRIAL

Abstract

Intravesical BCG with or without isoniazid provokes more side effects than epirubicin. Prophylactic isoniazid does not reduce the side effects of BCG, while BCG with or without isoniazid prolongs the time to first recurrence compared to epirubicin. Further followup is required before long-term conclusions can be made for progression-to-muscle invasive disease and survival.
