Prognosis for non‐small cell lung cancer patients with brain metastases

Abstract

Our results show that the number of brain metastases, classified by group A (<4) or group B (≥4) did not influence the overall survival of NSCLC patients. However, the overall survival in group A was better than in group B when analyzed, except for local brain treatment modalities in sub-group analysis, suggesting that non-optimized local treatment strategies might cause an unexpected prognosis result in this retrospective study. We suggest that more prospective studies might be needed for the optimal standard treatment for brain metastasis.
