Background: The clinical significance of lipid profile in gastric cancer remains unclear. The aim of the present study was to investigate the correlation between serum lipid profiles and patient clinical parameters as well as prognosis in gastric cancer.
Methods: The preoperative plasma lipid profile levels of 358 gastric cancer patients, who were operated in between 2001 and 2009, were retrospectively evaluated, and the correlation between these factors and patient clinical parameters as well as survival were analyzed.
Results: There was a significant association between serum high-density lipoprotein cholesterol level (HDL-C <54.2 mg/dL) and cancer progression, Logistic regression analysis revealed that lower level of serum HDL-C was an independent risk factor for deeper cancer invasion, nodal metastasis as well as late stage in patients with gastric cancer. However, no significant association was reported between other lipid markers [triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), very low-density lipoprotein (VLDL) and apolipoprotein A (apoA)] and lymph node involvement as well as stage of disease. In univariate analysis and multivariate analyses regarding patient's survival, there was no significant association between the groups in terms of TG, TC, HDL-C, LDL-C, VLDL and apoA.
Conclusions: Low level of serum HDL-C in gastric cancer correlates with cancer progression but not patient's survival.
