摘要
Aim: This study investigated the overall and histology subtype-specific results of antiangiogenic agents combined with chemotherapy versus chemotherapy alone for the first-line treatment of advanced non-small cell lung cancer (NSCLC). Methods: Literature retrieval, trial selection, data collection, and statistical analysis were performed according to the Cochrane Handbook. The outcome measures were tumor response rate, progression-free survival (PFS), overall survival (OS), and adverse effects. Results: 13 randomized controlled trials comprising 5,451 patients were included. The meta-analysis showed a higher response rate (risk ratio (RR) 0.63, 95% confidence interval (Cl) 0.53-0.74) and a significantly prolonged PFS (hazard ratio (HR) 0.75, 95% Cl 0.66-0.85) and OS (HR 0.92, 95% Cl 0.86-0.98) in the groups combining antiangiogenic agents with chemotherapy versus the chemotherapy alone groups. In the histology subgroup analysis, treatment with antiangiogenic agents plus chemotherapy significantly improved the RR, PFS, and OS as compared with the chemotherapy groups in patients with nonsquamous NSCLC, but not in those with squamous NSCLC. The risk of grade 3/4 thrombocytopenia, hypertension, bleeding, proteinuria, rash, diarrhea, fatigue, headache, anorexia, and febrile neutropenia was significantly increased in the antiangiogenic agent combination groups as compared with the chemotherapy groups. Conclusion: The use of antian-giogenic agents in addition to chemotherapy is a valid option for the first-line treatment of advanced NSCLC. The benefit is restricted to patients with nonsquamouscell tumors.
