This study targeted patients with resectable stage II-IIIA non-small cell lung cancer with EGFR mutation
NSCLC patient with EGFR sensitive mutation as confirmed by needle biopsy;
At stage II-IIIA (TNM Staging, Version 8) as identified by chest CT, PET-CT or/and EBUS;
No systemic metastasis (confirmed by head MRI, whole body bone scan, PET-CT, liver and adrenal CT, etc.);
With the feasibility to receive radical surgery ;
The patient has undergone any systemic anti-cancer treatment for NSCLC, including surgical treatment, local radiotherapy, cytotoxic drug treatment, targeted drug treatment and experimental treatment, etc.;
The patient suffers from any unstable systemic disease (including active infection, uncontrolled hypertension, unstable angina pectoris, angina pectoris that starts to attack within the last 3 months, congestive heart failure [≥ Grade II specified by New York Heart Association (NYHA)], cardiac infarction (6 months before enrollment), severe arrhythmia and liver, kidney or metabolic diseases that requires drug treatment;
The patient is a carrier of HIV;
The patient has had or is currently suffering from interstitial lung disease;

Major pathologic response (MPR)
MPR is defined as the proportion of participants who have achieved major pathologic response (on routine hematoxylin and eosin staining, tumors with no more than 10% viable tumor cells) in all participants who have completed the neoadjuvant therapy before surgery
Objective response rate (ORR)
It refers to the proportion of patients who have had a complete response or partial response (according to RECIST1.1) as confirmed by CT evaluation after 3 weeks in all patients who have completed the neoadjuvant therapy. Only patients with measurable lesions at baseline will be analyzed.
Progression-free survival (PFS)
It refers to the time (months) from the first administration of drug in this study to the disease progression or death (including any cause of death in the case of no progression) as recorded in CRF, regardless of whether the patient exits from the treatment or receives other anti-cancer treatment before progression.
Event-free survival (EFS)
Event-free survival (EFS) is defined as the length of time (months) from randomization to any of the following events: any progression of disease precluding surgery, progression or recurrence disease based on response evaluation criteria in solid tumors (RECIST) 1.1 after surgery, or death due to any cause. Participants who don't undergo surgery for reason other than progression will be considered to have an event at progression or death. Progression is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression).
Disease-free survival (DFS)
It refers to the time (months) from radical surgery to relapse or death of a participant due to disease progression. In the case of a patient who still survives at the time of analysis, the latest evaluation date will be used for interpolation (censoring).
