MPR was defined as percentage of tumor cells within tumor bed less than 10% for primary lung lesions
The pathological complete response is defined as the absence of residual tumor in both lung and lymph nodes after neoadjuvant treatment.
ORR is the number of participants with a Complete Response (CR) and Partial Response (PR) divided by the total number of participants. Response is based on the Response Evaluation Criteria In Solid Tumors (RECIST 1.1) criteria. Complete Response (CR) was defined as the disappearance of all target lesions. Partial Response (PR) was defined as at least a 30% decrease in sum of longest diameter of target lesions compared to baseline or the complete disappearance of target lesions, with persistence of 1 or more nontarget lesion(s) and no new lesions.
