Abstract
Abstract Objective The aim of the study was to study the correlation between the clinicopathological parameters of lung adenocarcinoma and lymph node metastasis and identify the risk factors of lymph node metastasis. Methods The data of 258 patients with postoperative lung adenocarcinoma (mainly based on their pathological data) were collected and analyzed, and their basic information was counted. Results Maximum tumor diameter was found to be an independent risk factor for lymph node metastasis. The larger the maximum diameter of the tumor in patients with lung adenocarcinoma, the higher the likelihood of lymph node metastasis. Solid predominant adenocarcinoma with mucin production is as an independent risk factor for superior mediastinal and subcarinal lymph node metastasis. Primary adenocarcinomas in the lower lobe of the lung may have a higher rate of lymph node metastasis than those in the upper lobe. Conclusion The known pathological subtypes of lung adenocarcinoma can be used for the prediction of lymph node metastasis in various regions and guide the dissection of lymph nodes that would improve patients' prognosis.
