Sumario:Abstract Objective The aim of the present work was to investigate the response and safety of whole‐brain radiotherapy (WBRT) plus temozolomide (TMZ) for patients with brain metastases of non‐small‐cell lung cancer (NSCLC). Methods The electronic databases of Pubmed, EMbase, Cochrane, Wangfang, china national knowledge infrastructure (CNKI), and Google scholar were systematically searched to identify the prospective randomized trials relevant to WBRT plus TMZ for patients with brain metastases of NSCLC. The data associated with treatment response and toxicity were extracted from original included studies. The relative risk (RR) for treatment response and toxicity between WBRT+TMZ and WBRT alone was pooled by fixed or random effect model. Publication bias was investigated by Begg's funnel plot and Egger's line regression test. Results Twenty‐five clinical trials fulfilled the inclusion criteria and were included in the meta‐analysis. The pooled results showed WBRT+TMZ can significant improve the objective response rate (ORR) compared with WBRT alone (RR = 1.43, 95% confidence interval [CI] 1.32–1.55, p < 0.05) under a fixed effect model. WBRT+TMZ significantly increased the III–IV hematological toxicity compared to WBRT alone (RR = 1.66, 95% CI 1.12–2.54, p < 0.05) in the fixed effect model. Grade III–IV gastrointestinal toxicity was increased in WBRT+TMZ compared to WBRT alone (RR = 1.72, 95% CI 1.29–2.30, p < 0.05). Begg's funnel plot and Egger's line regression test indicated publication bias. Conclusion Based on the present work, WBRT+TMZ can improve the ORR for brain metastases of NSCLC, but the risk of treatment‐associated grade III/IV hematological toxicity and gastrointestinal toxicity were also increased compared to WBRT alone.
