What are the chances of bladder cancer returning after BCG treatment?
The standard of care for patients with high-grade (HG) non-muscle invasive bladder cancer (NMIBC) remains intravesical bacillus Calmette-Guérin (BCG) following transurethral resection. Unfortunately, up to 75% will develop tumor recurrence and 20% will progress within 5 years despite intravesical therapy.
How long does BCG stay active?
