Likewise, although the J82 cell line did not appear to be sensitive to either BCG or interferon alfa-2b alone, the combination of BCG plus interferon alfa-2b had an antiproliferative effect. Efficacy Based on the clinical rationale for combining BCG and interferon alfa-2b, a number of centers have investigated this combination in patients with superficial bladder cancer .

However, observations that intra- vesical interferon alfa-2b therapy has substantial activity in up to 20% of patients who failed BCG therapy 20,21 are extremely encouraging and suggest that one important application of interferon alfa-2b is in the treatment of BCG failures. Safety Intravesical interferon alfa is associated with minimal local toxicity. The most common adverse events are mild fever and flulike symptoms, which occur in <30% of treated patients. 22 No dose-limiting toxicity has been . . . . . .
