Intravesical chemotherapy plus bacille Calmette-Guérin in non-muscle invasive bladder cancer: a systematic review with meta-analysis.

Unlabelled: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Non-muscle-invasive bladder cancer has a significant recurrence and progression rate despite transurethral resection. The current standard of care to lower the risk of recurrence and progression is adjuvant BCG followed by maintenance BCG. Despite this, a significant number of patients experience recurrence and progress to invasive cancer.
