- Lung cancer is one of causes of the malignant tumor-associated death on a global scale, in which the surgery is the only effective approach in patients with non-small cell lung cancer (NSCLC). As present, the total postoperative 5-year survival rate of NSCLC is 40%, while only 4%～15% patients can benefit from adjuvant chemotherapy[1]. American National Comprehensive Cancer Network (NCCN) manual recommends that adjuvant chemotherapy can be performed on NSCLC patients in phase Ⅱ～ⅢA.
