To Evaluate the Efficacy and Safety of Gefitinib in Adjuvant Chemotherapy for Lung Adenocarcinoma

Observational Clinical Trial of Adjuvant Chemotherapy for Non-squamous Cell Carcinoma of Non-small Cell Lung Cancer

The purpose of this study was to evaluate the efficacy and safety of targeted gefitinib versus oral vinorelbine and carboplatin in EGFR-mutant NSCLC patients.

The purpose of this study was to evaluate the efficacy and safety of targeted gefitinib versus oral vinorelbine and carboplatin in EGFR-mutant NSCLC patients. The purpose is to explore the role of TKI in neoadjuvant therapy, and to further improve disease-free survival (DFS) and pathologic complete remission (pCR) in EGFR-mutant populations; and reduce surgical complications and mortality.

OBJECTIVES: To evaluate the efficacy of oral gefitinib versus neoadjuvant vinorelbine and carboplatin in operable stage II-IIIA EGFR-mutant non-squamous NSCLC patients, with a 2-year disease-free survival rate. 2yDFS).

Secondary objective: To evaluate pCR, 0RR, and other efficacy measures (safety, complete) for oral gefitinib vs. neoadjuvant vinorelbine and carboplatin in patients with operable stage II-IIIA EGFR-mutant non-squamous cell carcinoma NSCLC. Resection rate, tumor regression, mediastinal lymph node clearance, perioperative complications, and mortality rate).
