Brain metastases in patients with EGFR -mutated or ALK -rearranged non-small-cell lung cancers

Brain metastases (BM) are common in non-small-cell lung cancer (NSCLC). However, the baseline incidence and evolution of BM over time in oncogene-driven NSCLCs are seldom reported. In this study, we evaluated the frequency of BM in patients with epidermal growth factor receptor (EGFR)-mutated or anaplastic lymphoma kinase (ALK)-rearranged NSCLC.The presence of BM, clinicopathologic data, and tumor genotype were retrospectively compiled and...
