Icotinib for Completed Resected IB NSCLC With EGFR Mutation

Adjuvant chemotherapy have shown little evidence of survival benefit in patients with stages IB non-small cell lung cancer (NSCLC) after complete resection. Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) show great efficacy in patients with EGFR mutant non-small cell lung cancer (NSCLC). Icotinib is a novel EGFR-TKI developed by a group of Chinese scientists and clinician. In the phase III ICOGEN trial, icotinib had non-inferiority efficacy to gefitinib with better safety. This study is studying icotinib to see how well it works in treating patients with fully resected stage IB NSCLC harboring EGFR mutation.
