Conflicting reports of the necessity for percutaneous bacillus Calmette-Guerin (BCG) administration with intravesical BCG prompted us to evaluate its benefit in a randomized prospective comparison of intravesical versus intravesical with percutaneous BCG therapy. Intravesical Tice BCG was given in a dose of 50 mg. with or without percutaneous BCG weekly for 6 weeks, at 8, 10 and 12 weeks, at 6 months and every 6 months thereafter. Tumor recurrence was documented in 13 of 30 patients (43%) receiving only intravesical BCG and in 15 of 36 patients (42%) receiving intravesical plus percutaneous BCG. The addition of percutaneous BCG to intravesical therapy did not increase treatment efficacy in this study.
