Abstract:
(1) Surgery is the first method to cure early stage non-small cell lung cancer (NSCLC). Ground glass nodule (GGO) like lung adenocarcinoma should be regarded as a new clinical issue to avoid over-treatment. The deep meaning of multidisciplinary pathological classification of lung adenocarcinoma should be fully understood to avoid over-diagnosis. The T staging of lung adenocarcinoma mixed with GGO components should be correctly understood to avoid over-staging. We should carefully understand the new data of relationship between sublobectomy and prognosis to avoid excessive resection. Attention should be paid to the research progress of minimal residual disease (MRD) to avoid insufficient treatment. (2) The treatment strategy of resectable stage Ⅲ NSCLC should be surgery with individualized systemic treatment. Locally advanced NSCLC dominated by Ⅲa-N2 NSCLC is a kind of disease with high multi-dimensional heterogeneity. In theory, preoperative treatment is superior to postoperative treatment, and molecular diagnosis should be made along with pretreatment staging, so as to select preoperative treatment. The patients with negative driver gene mutation obtained better pathological complete response/major pathological response (PCR/MPR) from immunotherapy compared to those from chemotherapy, and the better PCR/MPR is expected to be transformed into overall survival (OS). The data of preoperative treatment in patients with positive driver gene mutation are few, whereas the data of postoperative targeted treatment are much better than those of postoperative chemotherapy. (3) The effective systemic treatment strategy has "created" many long-term survivors with stage Ⅳ NSCLC, and has changed the original concept and population of "oligometastasis". Attention should be paid to the individual ineffective lesions in stage Ⅳ patients with long-term survival. It is also necessary to explore how to intervene in the resection of "oligometastasis" of stage Ⅳ NSCLC at an appropriate time and in an appropriate way, which may be one of the main tasks of lung cancer surgery in the future.
