EGFR Tyrosine Kinase Inhibitor (TKI) Combined With Concurrent or Sequential Chemotherapy for Patients With Advanced Lung Cancer and Gradual Progression After First-Line EGFR-TKI Therapy: A Randomized Controlled Study.

Abstract：

INTRODUCTION:Continuing tyrosine kinase inhibitor (TKI) therapy may be beneficial when patients with non-small-cell lung cancer and EGFR mutations experience gradual disease progression after initial EGFR-TKI treatment. We aimed to compare the efficacy of simultaneous EGFR-TKI and chemotherapy with that of sequential treatment after patients' disease gradually progressed after first-line EGFR-TKI treatment. PATIENTS AND METHODS:Patients with gradual progression who were EGFR-T790M mutation negative were randomly divided into two groups. In the concurrent group, patients were treated with pemetrexed plus cisplatin along with the same EGFR-TKI. In the sequential group, patients continued with EGFR-TKI until the disease progressed again, according to RECIST, then switched to chemotherapy. We evaluated the patients' progression-free survival (PFS) and overall survival times. RESULTS:Ninety-nine patients were enrolled: 49 in the concurrent group and 50 in the sequential group. The median PFS (mPFS) was 7.7 months (95% confidence interval [CI], 3.6-11.7) in the concurrent group and 5.7 months (95% CI, 3.5-7.9) in the sequential group (hazard ratio = 0.66; 95% CI, 0.44-1.00; P = .026), respectively. For the sequential group, the mPFS1 and mPFS2 were 1.8 months (95% CI, 1.4-2.3) and 3.8 months (95% CI, 3.1-4.5), respectively. The median overall survival of the concurrent group was longer than that of the sequential group (20.0 vs. 14.7 months; hazard ratio = 0.52; 95% CI, 0.32-0.85; P = .038). CONCLUSION:For patients with advanced non-small-cell lung cancer and gradual progression who are EGFR-T790M mutation negative after initial EGFR-TKI therapy, EGFR-TKI combined with chemotherapy confers longer PFS and overall survival than sequential EGFR-TKI and chemotherapy does.
