Predictive Factors for Lymph Node Metastasis in Clinical Stage I Part-Solid Lung Adenocarcinoma

BackgroundAccurate clinical staging of tumors with a small solid portion is essential for developing an appropriate treatment plan. This study evaluated predictive factors lymph node (LN) metastasis in patients stage I part-solid lung adenocarcinoma.MethodsMedical records adenocarcinoma who underwent anatomic pulmonary resection systematic evaluation between January 2009 and June 2018 were retrospectively reviewed. To identify LN metastasis, univariate multivariable logistic regression analyses performed.ResultsAmong the 593 this study, overall prevalence was 3.7% (n = 22), which included 3.0% 18) N1 1.5% 9) N2 metastasis. Combined nodal involvement observed 5 patients. Nodal not sized 1.1 cm or smaller. The rates cT1b, cT1c, cT2a 5.5% (13 237), 7.1% (6 84), 13.6% (3 respectively. According to analysis, size (P .015) high maximum standardized uptake value (SUVmax) primary tumor .044).ConclusionsLarge SUVmax adenocarcinoma. Systematic should be performed, especially those have large tumor. Accurate Medical performed. Among .044). Large
