Icotinib Following Chemotherapy Versus Chemotherapy as Adjuvant Therapy in Stage IIA-IIIA NSCLC With EGFR Mutation

The purpose of this study is studying icotinib following chemotherapy to see how well it works compared to chemotherapy in treating patients with resected stage IIA-IIIA NSCLC harboring EGFR mutation.

Adjuvant chemotherapy is recommended for routine use in patients with fully resected stage IIA-IIIA non-small cell lung cancer (NSCLC). Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) show great efficacy in patients with advanced non-small cell lung cancer (NSCLC) with EGFR mutation. Icotinib is a novel EGFR-TKI developed by a group of Chinese scientists. In the phase III ICOGEN trial, icotinib had non-inferiority efficacy to gefitinib with better safety. In phase II trial, chemotherapy followed by 6-month gefitinib as adjuvant therapy can confer longer disease-free survival compared with chemotherapy alone in patients with resected stage IIIA-N2 non-small cell lung cancer harboring EGFR mutations. This study is to studying 6-month or 12-month icotinib following chemotherapy to see how well it works compared to chemotherapy in treating patients with resected stage IIA-IIIA NSCLC harboring EGFR mutation.
