description To evaluate the efficacy and safety of a combination regimen of gefitinib and pemetrexed as first-line chemotherapy in advanced EGFR-mutated non-small cell lung cancer (NSCLC) patients. Patients and methods Patients with advanced non-squamous NSCLC harboring asensitive EGFR mutation were included in this study and randomly divided into gefitinib + placebo group and gefitinib + pemetrexed group. Pemetrexed or placebo was administered on day 1 at a dose of 500 mg/m 2 , and gefitinib was sequentially administered on days 2 ~ 16. This treatment regimen was repeated every 3 weeks until disease progression. All investigators and participants were masked to treatment allocation. The overall response rate (ORR) and disease control rate (DCR) of gefitinib + pemetrexed group were higher than that of gefitinib + placebo group but only the difference of DCR between two groups was statistically significant ( P   0.05). The combination regimen of gefitinib + pemetrexed used in this study showed a higher ORR and DCR, longer median PFS and acceptable toxicity.
