However, the clinical benefits of bevacizumab plus cytotoxic chemotherapy for EGFR mutation–positive patients remain unclear. This study aimed to investigate VEGFA messenger RNA expression in patients with EGFR mutation, and to further compare the efficacy of bevacizumab combined with platinum-based chemotherapy between EGFR-mutant and wild-type patients. Patients and Methods: Gene expression of various proangiogenic factors was analyzed in nonsquamous, non–small-cell lung cancer (NSCLC) patients using The Cancer Genome Atlas dataset. Additionally, clinical data of patients receiving carboplatin and pemetrexed (CPem; n = 104) or bevacizumab plus CPem (BevCPem; n = 55) at Nagoya University hospital were retrospectively assessed for progression-free survival and best overall response rate (ORR). Results: Among various proangiogenic factors, only VEGFA expression was significantly higher in patients with advanced nonsquamous NSCLC with EGFR mutation compared to wild-type patients (P = .0476). Progression-free survival in the BevCPem group was significantly longer in patients with EGFR mutation than in wild-type patients (10.5 vs. 6.6 months; Wilcoxon P = .0278), while the difference in the CPem group was not significant (6.6 vs. 4.5 months; Wilcoxon P = .1822). The ORRs in the BevCPem group were 54.5% and 36.4% for EGFR-mutant and wild-type patients, respectively, and the ORRs in the CPem group were 35.5% and 28.8 % in EGFR-mutant and wild-type patients, respectively. Conclusion: VEGFA messenger RNA expression was significantly increased in advanced nonsquamous NSCLC harboring EGFR mutation, and BevCPem provided better clinical benefits to patients with EGFR mutation than wild-type carriers., ファイル公開日: 2021/05/01}, pages = {273--280.e4}, title = {Potential Benefits of Bevacizumab Combined With Platinum-Based Chemotherapy in Advanced Non–Small-Cell Lung Cancer Patients With EGFR Mutation}, volume = {21}, year = {2020} }
