Randomized Controlled Trial Multicenter Study
Randomized phase II trial of first-line treatment with pemetrexed-cisplatin, followed sequentially by gefitinib or pemetrexed, in East Asian, never-smoker patients with advanced non-small cell lung cancer.
Treatment with epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors or chemotherapy have shown improved survival outcomes in East Asian, never-smoker patients with non-small cell lung cancer (NSCLC). However, treatment sequence has not been optimized in patients with unknown EGFR mutation status. This trial compared first-line chemotherapy with pemetrexed (P)-cisplatin (C), followed by either gefitinib (G) or P maintenance. ⋯ East Asian never-smoker patients with advanced NSCLC and unknown EGFR mutation status had improved PFS following treatment with first-line PC and sequential G. Irrespective of subsequent maintenance treatment, induction PC was safe and efficacious, leading to prolonged OS in the Asian patient population.
