Prognostic Significance of Preoperative Serum Triglycerides and High-Density Lipoproteins Cholesterol for Patients with Non-Small Cell Lung Cancer: A Retrospective Study
Abstract Background: Abnormalities in serum lipids and lipoproteins have been documented to be associated with the risk of various cancers in recent years, but its prognostic value for cancer is not known. This study retrospectively evaluated the prognostic significance of preoperative serum lipids and lipoproteins for non-small cell lung cancer (NSCLC).Methods: A retrospective review was conducted of 551 patients with NSCLC. A receiver operative characteristic (ROC) curve was utilized to determine the optimal cut-off value and area under the ROC curve. Kaplan-Meier curves and a Cox proportional hazards model were used to perform survival analysis.Results: Serum lipids and lipoproteins had significant difference between NSCLC patients and healthy controls. Moreover, with a median follow-up of 42 months, the NSCLC patients in high triglycerides (TG) group and low High-density lipoprotein cholesterol (HDL-C) group exhibited shorter overall survival (OS) and disease-free survival (DFS). In multivariable analysis, preoperative TG and HDL-C can be identified as independent prognostic factors for OS and DFS in patients with NSCLC. Conclusion: Abnormalities of serum lipids and lipoproteins metabolism were associated with the survival outcomes of NSCLC. Preoperative serum TG and HDL-C may be promising biomarkers to predict prognosis for NSCLC patients.
