关键词: brain metastasis concurrent EGFR mutation nonsmall cell lung cancer sequential tyrosine kinase inhibitors whole brain radiotherapy

摘要:
To examine the outcomes of concurrent versus sequential whole-brain radiotherapy (WBRT) and epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) in nonsmall cell lung cancer (NSCLC) patients with EGFR mutation. Retrospectively 105 patients with NSCLC, brain metastasis, and EGFR mutation (Affiliated Hospital of Guangdong Medical University, 01/2011 to 12/2014) were grouped as: EGFR-TKIs alone (n=39, group A), EGFR-TKIs+concurrent radiotherapy (n=34, group B), and radiotherapy followed by EGFR-TKIs (n=32, group C). The intracranial objective response rates of groups A, B, and C were 66.7%, 85.3%, and 75%, respectively (P<.05). The median intracranial progression-free survival of groups A, B, and C were 6.8, 12.4, and 9.1 months, respectively (P<.05). The median extracranial progression-free survival of groups A, B, and C were 7.8, 9.4, and 8.3 months, respectively (P>.05). EGFR-TKIs and WBRT by simultaneous application improved the short-and long-term benefits to patients with NSCLC brain metastasis carrying EGFR mutation compared to concurrent application or EGFR-TKIs alone without additional adverse events.
