Purpose: To evaluate the prognostic role of the preoperative plasma lipid profile, including low-density lipoprotein -cholesterol [LDL-C], high-density lipoprotein-cholesterol [HDL-C], cholesterol, and triglycerides, in hepatocellular carcinoma patients undergoing radical resection.
Methods: Clinical data, including the preoperative plasma profile levels, were retrospectively collected and reviewed in 1411 hepatocellular carcinoma patients, who underwent operation between 2001 and 2010. Kaplan-Meier method and the Cox proportional hazards regression model were used in analyzing the DFS and OS.
Results: We found that HDL-C ≤ 0.88 mmol/L and cholesterol ≤ 4.420 mmol/L were preoperative risk factors of disease-free survival (DFS) and overall survival (OS). A decreased CHO level was significantly associated with decreased OS (HR, 0.800; 95% CI, (0.691-0.926), P =0.003) and decreased DFS (HR, 0.844; 95% CI, 0.737-0.966, P=0.012). Additionally, an increased HDL-C level was shown significant association with increased OS (HR, 0.679; 95% CI, 0.570-0.808, P<0.01) and DFS (HR, 2.085; 95% CI, 1.271- 3.422, P = 0.002). In the univariate and multivariate analyses involving OS and DFS, no significant relativity were observed between the LDL-C and TG groups.
Conclusions: Decreased levels of CHO and HDL might predict worse outcomes both DFS and OS for hepatocellular carcinoma patients.
