Adding interferon to BCG may be a viable option for improving outcomes in patients with high-risk or recurrent non-muscle invasive bladder cancer (NMIBC) who are unable or unwilling to undergo radical cystectomy, according to researchers.

Using interferon alfa-2b with BCG is the current practice at their institution for NMIBC patients unable or unwilling to undergo radical cystectomy, the next management step recommended by guidelines. The investigators analyzed the outcomes of the combination…
