AIM To evaluate the clinical results of external-beam radiotherapy (EBRT) for muscle-invasive bladder cancer (MIBC) in elderly or medically-fragile patients. PATIENTS AND METHODS Twenty-five consecutive patients with MIBC (cT2-4N0-1M0) receiving EBRT were retrospectively analyzed. Their median age was 82 years. Radiotherapy median dose was 60 Gy administered in 30 fractions. RESULTS Median follow-up period was 14.7 months. Median overall survival (OS) and progression-free survival (PFS) were 14.7 months and 7.8 months, respectively. The OS, cause-specific survival (CSS), and PFS rates at 1-year were 56.0%, 68.5%, and 40.0%, respectively. The local progression-free rates (LPFR) at 6 months and 1 year were 89.3% and 59.5%, respectively. Performance status 3 was a significantly unfavorable factor for OS, CSS, and progression-free survival; clinical N stage was a significantly unfavorable factor for progression-free survival; and lower irradiation dose (≤50.4 Gy) was a significantly unfavorable factor for LPFR. CONCLUSION EBRT for elderly or medically-fragile patients is feasible, and achieves acceptable local progression-free status.
