Is delay to radical cystectomy following BCG failure oncologically safe

Radical cystectomy is advocated for patients with high-risk non-muscle-invasive bladder cancer who develop disease recurrence following BCG therapy. A retrospective series suggests that a delay in radical cystectomy attributable to failure of salvage bladder-preserving therapies in this patient cohort is safe. However, a closer analysis of the study reveals inherent case selection that might limit such conclusions.
