Abstract
Currently, recurrence of carcinoma in situ (CIS) after intravesical BCG mandates a radical cystectomy, as BCG-refractory CIS is aggressive with a high propensity for progression. Novel intravesical agents are needed to salvage refractory disease. Gemcitabine is an antimetabolite with proven single agent efficacy against metastatic bladder cancer. In this review, the ability of gemcitabine to treat BCG-refractory CIS is examined in preclinical, phase I and phase II trials. Future studies with intravesical gemcitabine are also examined.
