Introduction: Radiotherapy (RT) is a frequently offered treatment option for brain metastases (BMs) in patients with non-small-cell lung cancer (NSCLC). This study presents patient-reported outcomes (PROs) in a cohort of NSCLC with BMs treated with RT. This study researched how PRO scores at the start of RT may be useful in survival estimates and how PROs change over time after RT. Methods: NSCLC patients with first-time BMs treated with RT were identified in a prospective observational study. PROs were collected at the start of RT and monthly for up to 1 year. Differences in PRO mean scores at the start of RT (M0) and at month 2 (M2) after treatment are reported. Prognostic values of PROs were analyzed in a stepwise adjusted Cox model. Results: Of 294 patients identified, 239 (81%) responded at M0; 105/239 (44%) responded at both M0 and M2. High scores for weakness of legs at M0 were associated with short survival when adjusting for performance status and status of extracranial metastases. Those responding at M0 only had worse mean scores for overall QoL and PF but similar scores for fatigue and dyspnea compared to patients responding over time. At M2, patients with <6 months survival after RT reported worse scores for overall QoL, PF, fatigue, and dyspnea; long-term survivors reported stable scores. Conclusions: NSCLC patients diagnosed with BMs and expected survival < 6 months should be offered optimal palliative care rather than RT.
