Lung cancer is the most common cause of cancer mortality in men and women in the world. LACE meta analysis shows that the 5-year survival rate of post-operation chemotherapy group rose by 5.4%, therefore, adjuvant chemotherapy has been the main treatment after surgery according to National Comprehensive Cancer Network (NCCN) Guideline. But patients have poor compliance due to physical condition after surgery. Compared with adjuvant chemotherapy, neoadjuvant therapy has better patient compliance and tolerance.Targeted therapy, with milder side effect compared with chemotherapy, may be a promising choice to treat NSCLC previously. But to date, there is no enough evidence to support the efficacy and safety of neoadjuvant targeted therapy in patients with EGFR mutation.The purpose of this study is to evaluate the efficiency and safety of Gefitinib Neoadjuvant Therapy vs Oral Navelbine Carboplatin Neoadjuvant Therapy for Resectable NSCLC patients harboring EGFR mutation.
