Lymph node evaluation and surgical procedure selection for non-small cell lung cancer

Lymph node metastasis is a common mode of metastasis in non-small cell lung cancer (NSCLC). Correct lymph node staging is crucial to the selection of treatment and the assessment of the prognosis of patients, and the selection of appropriate lymph node resection can prolong the survival of patients and reduce surgical trauma.In this review, the preoperative lymph node evaluation methods and the common intraoperative lymph node resection methods of NSCLC are reviewed, and the advantages and disadvantages of each method are compared. The purpose of this review is to summarize the latest research progress in the evaluation and resection of NSCLC lymph nodes, so as to select appropriate evaluation and resection methods in clinical work.
