Aims. To evaluate whether reduced waiting time influences survival of patients treated with whole-brain radiotherapy (WBRT) for brain metastases. Materials and Methods. Retrospective intention-to-treat study including 110 patients treated with primary WBRT (typically 10 fractions of 3 Gy; no other treatment between diagnosis and WBRT). Uni- and multivariate tests were performed. Results. Median delay between imaging diagnosis and WBRT was 12 days (range 0–66 days). WBRT started within 1 week in 36%, during the second week in 28%, and during the third week in 18% of patients. No significant correlation between waiting time and survival was evident, except for one subgroup of patients. Those without extracranial metastases (potentially more threatened by worse intracranial disease control) survived for a median of 2.5 months from WBRT if waiting time was 2 weeks or longer as compared to 5.6 months if waiting time was shorter than 2 weeks (). The same correlation was seen if survival was computed from imaging diagnosis. Conclusion. If departmental resources are not sufficient to provide immediate WBRT within 2 weeks to all patients, those without extracranial metastases should be prioritised. This study did not address the impact of waiting time on quality of life or symptom palliation.
