THE RESULTS OF CHAIN OF CHEMOTHERAPY AND ANTI-EGFR DRUGS IN PATIENTS WITH ADVANCED STAGE LUNG CANCER
Main Article Content
Abstract
Aims: Evaluation of the results of chemotherapy and anti-EGFR drugs in patients with advanced stage lung cancer. Population: The patient was diagnosed stage IV non-small cell lung cancer, received oral erlotinib after 4-6 cycles platinum-containing regimen chemotherapy at National Cancer Hospital from January 2016 to June 2020. Patients and Methods: Retrospective combined prospective study. Results: The overall response rate and disease control rate with platinum-based chemotherapy was 52.4% and 81%, respectively. The overall response rate and disease control rate after 3 months of erlotinib treatment was 33.4% and 93.6%; After 12 months, the overall response rate was 43.0% and the disease control rate was 70.5%. PFS with erlotinib was superior in patients with cutaneous adverse events and response to first-line chemotherapy. Conclusion: Response rates to chemotherapy are higher in patients with EGFR mutations. Progression-free survival with erlotinib is associated with cutaneous adverse events and response to first-line chemotherapy.
