PURPOSE To investigate the efficacy of gefitinib as an adjuvant therapy for non–small-cell lung cancer patients with EGFR mutation. PATIENTS AND METHODS IMPACT (WJOG6410L; University Hospital Medical Information Network Clinical Trials Registry: UMIN000006252 ), a randomized, open-label, phase III study, included patients with completely resected pathologic stage II-III non–small-cell lung cancer harboring EGFR mutations (exon 19 deletion or L858R) during September 2011 to December 2015. Patients were randomly assigned to receive gefitinib (250 mg once daily) for 24 months or cisplatin (80 mg/m2 on day 1) plus vinorelbine (25 mg/m2 on days 1 and 8; cis/vin) once every 3 weeks for four cycles. The primary end point was disease-free survival (DFS). RESULTS Overall, 234 patients were randomly assigned. Among 232 eligible patients (116 each; excluding two who withdrew consent), the median DFS was 35.9 and 25.1 months in the gefitinib and cis/vin groups, respectively. However, Kaplan-Meier curves crossed around 4 years after surgery with no statistically significant difference (stratified log-rank P = .63; hazard ratio by stratified Cox proportional hazards model = 0.92; 95% CI, 0.67 to 1.28). Overall survival (OS) was also not different (stratified log-rank P = .89; hazard ratio = 1.03; 95% CI, 0.65 to 1.65), with the 5-year OS rates being 78.0% and 74.6% in the gefitinib and cis/vin groups, respectively. Treatment-related deaths occurred in 0 and three patients in the gefitinib and cis/vin groups, respectively. CONCLUSION Although adjuvant gefitinib appeared to prevent early relapse, it did not prolong DFS or OS. However, similar DFS and OS may justify adjuvant gefitinib in the selected patient subsets, especially those deemed ineligible for platinum-doublet adjuvant therapy; however, this was not a noninferiority trial.

TPS7110 Background: Vinorelbine plus cisplatin after completely resected stage II-III non-small cell lung cancer (NSCLC) is a standard therapy. Stage IV non-small cell lung cancer (NSCLC) harboring mutations in the epidermal growth factor receptor (EGFR) is quite sensitive to tyrosine kinase inhibitors (TKIs). Three randomized trials demonstrated that gefitinib is superior to platinum based chemotherapy in progression free survival. Retrospective analysis of adjuvant TKIs therapy for patient with resected lung cancer harboring EGFR mutation showed favorable trend toward improvement in disease free survival (DFS) and overall survival (OS). (J Thorac Oncol. 2011;6: 569–575) BR19 comparing adjuvant gefitinib vs. placebo for completely resected NSCLC without any selection of biomarker was closed early and did not show any benefit of adjuvant gefitinib, even in the EGFR mutation positive cohort. The randomized trial in adjuvant therapy with erlotinib vs. placebo for patients with overexpression of EGFR protein has complete enrolment already. We conduct the first randomized phase III trial comparing adjuvant gefitinib with chemotherapy in patients with completely resected stage II-III NSCLC harboring EGFR mutations. Methods: Patients who have undergone complete resection and have EGFR mutation, deletions in exon 19, or L858R point mutation at exon 21 and without T790M mutation are randomly assigned gefitinib 250mg a day for 2 years or vinorelbine 25mg/m2 days 1 and 8, plus cisplatin 80mg/m2 day 1, every 3 weeks for 4 courses. The primary endpoint is DFS and secondary endpoints are OS and safety. On the basis of previous studies, we assume the hazard ratio of DFS is 0.65. To demonstrate this improvement in DFS, 230 patients in total would be needed during 3-year accrual period. This trial has begun from September 12 among 22 institutes in Japan. Until now (January 31. 2012), 13 cases have been enrolled. Five cases were enrolled in latest 1 month.
