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