摘要

Radical cystectomy (RC) is traditionally considered the standard treatment for non-metastatic muscle-invasive bladder cancer (MIBC), although randomized evidence of superiority over bladder-preserving therapy (BPT) is lacking. In this nationwide study, we included all patients diagnosed with non-metastatic MIBC between 2017 and 2019 and treated with curative-intent with either RC or BPT. A total of 1,432 patients were included (1,101 RC, 331 BPT). The primary endpoint was 2‑year disease-free survival (DFS), with overall survival (OS) as the secondary endpoint. IPTW-adjusted 2‑year DFS was 61.5% for BPT and 55.3% for RC (HR 0.84; 95%-CI 0.69–1.05). Two-year OS was 74.0% for BPT versus 66.0% for RC (HR 0.80; 95%-CI 0.64–0.98). DFS was comparable between groups, while OS favored BPT.
