Erlotinib in Post Radical Operation NSCLC Patients With EGFR Mutation

This study is to compare 2-year Disease Free Survival Rate (DFSR) in post radical operation IIIA Non-Small Cell Lung Cancer (NSCLC) patients with Epidermal Growth Factor Receptor (EGFR) 19 or 21 exon mutation treated Erlotinib vs NP chemotherapy as adjuvant therapy.
