TREATMENT RESULTS OF PEMETREXED-CARBOPLATIN REGIMEN AS SECOND-LINE FOR NON–SMALL CELL LUNG CANCER AFTER EGFR TKIs ACCQUIRED RESISTANCE
Main Article Content
Abstract
Objective: To evaluate the treatment results of Pemetrexed - Carboplatin regimen in patients with non-small cell lung cancer after Tyrosin Kinase inhibitor accquired resistance. Objects and methods: Retrospective of 46 patients after accquired resistance to EGFR TKIs, on Pemetrexed - Carboplatin regimen, with longitudinal follow-up. Results: Rate of objective response 50%; complete response 0%; disease control 78.3%. Prognostic factors for poorer response: performance status PS1, stage IV, CNS metastasis. Median progression - free survival: 4 months. Conclusion: Pemetrexed - Carboplatin regimen is an appropriate treatment choice for patients with non-small cell lung cancer after resistance to Tyrosin Kinase inhibitors.
