Background and aim: Although there are some reports of an adverse effect of low serum high-density lipoprotein cholesterol (HDL-C) levels on gastrointestinal cancers, the specific correlation between serum HDL-C levels and gastric cancer remains unknown.
Methods: Preoperative serum HDL-C levels were retrospectively examined in 184 patients who had undergone gastrectomy. The patients who had undergone gastrectomy were divided into two groups: the normal-HDL-C group and the low-HDL-C group. We examined the characteristics and outcomes of these two groups. Univariate and multivariate analyses were performed to investigate the association between serum HDL-C levels and gastric cancer.
Results: There was no significant difference between the groups in terms of the progression of gastric cancer. In the low-HDL-C group, lymphatic and vascular invasion was significantly increased. The prognosis of the patients in the normal-HDL-C group was significantly better than those in the low-HDL-C group.
Conclusions: In this study, a positive correlation between low preoperative serum HDL-C levels and prognosis for gastric cancer was demonstrated. Serum HDL-C level may be a clinical prognostic factor for gastric cancer patients.
