Since the first reported case of using adjuvant topical immunotherapy utilizing bacillus Calmette-Guérin (BCG) was published by Herr and associates, several institutions have utilized numerous agents for topical infusion therapies (BCG, Mitomycin, Epirubicin, Thiotepa or combination therapy of BCG/INF) as adjuncts in the treatment of upper tract papillary transitional cell carcinoma. A comprehensive review of the current data in the treatment of upper tract transitional cell carcinoma (Ta/T1 disease) with adjuvant BCG therapy was completed. Currently, the efficacy of adjuvant BCG therapy was not demonstrated.
