Abstract

Introduction: Neoadjuvant chemotherapy followed by radical cystectomy (RC) and pelvic lymph node dissection is the standard radical management for muscle‐invasive bladder cancer (MIBC). However, major pelvic surgery is not suitable for all patients and combined modality therapy (CMT) offers an alternative for patients who want to retain their bladder. Brachytherapy (BT), as part of CMT, has been offered in selective cases of bladder cancer.

Objectives: To evaluate the clinical effectiveness of BT for solitary urinary bladder tumours in terms of survival, local recurrence (LR) rates, and adverse events.

Methods: A systematic review was conducted using defined search terms using online databases. Articles that discussed the use of BT as part of multi‐modality treatments for MIBC were included.

Results: Searches returned 112 articles of which 20 were deemed suitable for analysis. In all, 15 of the 20 articles reported overall survival (OS) at 5 years, 2747 patients were at risk and 1670 were alive after 5 years (60%): seven studies reported OS at 10 years, with 817 patients at risk and 350 alive at 10 years (42%). Disease‐specific survival at 5 years was reported in four studies, with 371 patients at risk and 279 alive (75%) at 5 years. LR rates were reported across all 20 studies and ranged from 0% to 32%.

Conclusion: Brachytherapy as part of CMT for MIBC is not a standard technique. It is an effective treatment in experienced centres for a selected patient population who wish to preserve their bladder. In such patients, CMT‐BT is well tolerated with an acceptable safety profile.
