Effectiveness of postoperative radiotherapy after radical cystectomy for locally advanced bladder cancer

Background Local‐regional failure (LF) for locally advanced bladder cancer (LABC) after radical cystectomy (RC) is common even with chemotherapy and is associated with high morbidity/mortality. Postoperative radiotherapy (PORT) can reduce LF and may enhance overall survival (OS) but has no defined role. We hypothesized that the addition of PORT would improve OS in LABC in a large nationwide oncology database. Methods We identified ≥ pT3pN0‐3M0...
