Clinical Characteristics and Prognosis of Sub-centimeter Lung Adenocarcinoma

This study analyzed the clinical characteristics and prognosis of patients with sub-centimeter lung adenocarcinoma in orde r to provide the basis for the diagnosis and treatment of such patients. Methods A retrospective study was performed to analyze patients with sub-centimeter lung adenocarcinoma who underwent VATS in Peking University People’s Hospital from January 2012 to December 2016. Patients were divided into pure ground-glass nodules (pGGN) group, mixed ground-glass nodules (mGGN) group and solid nodules (SN) group according to the features of nodular imaging. The clinical characteristics of the three groups were compared and the subgroup analysis of nodules in different diameter was performed. We also performed multivariate logistic regression analyses to identify the risk factors for sub-centimeter lung invasive adenocarcinoma. Results The study included 182 patients (57 men and 125 women) with a median age of 54 (27-75) years. Female sub-centimeter lung adenocarcinoma patients had a significant ly lower proportion of non-smoking history than males (P5 mm are independent risk factors for sub-centimeter lung invasive adenocarcinoma. For patients with sub-centimeter lung adenocarcinoma, early detection and appropriate surgical intervention can lead to a good prognosis. DOI: 10.3779/j.issn.1009-3419.2019.08.04
