Patients and Methods: We performed a retrospective single institution analysis of 76 patients with favorable prognosis. In contrast to the QUARTZ trial, inclusion was not limited to patients with non-small cell lung cancer (NSCLC). Furthermore, a cohort treated with higher total doses of WBRT was included (10 fractions of 3 Gy). Results: All patients were younger than 60 years or had a graded prognostic assessment score of 2.5-3. The median survival was significantly shorter after best supportive care (1.2 months; 3.2 months after WBRT with 5 fractions of 4 Gy and 3.9 months after 10 fractions of 3 Gy). Also, in multivariate analyses, survival was significantly better after WBRT. Further favorable prognostic factors included better performance status, no or limited extracranial metastases and primary tumor other than gastrointestinal. Conclusion: In line with the QUARTZ trial results, WBRT prolonged survival in patients with favorable prognostic features. ER -
