Purpose: Immunonutritional status is a known prognostic correlate in the context of gastric cancer (GC). In the present study, we investigated the prognostic relevance of a lipid profile-based immunonutritional score in patients with GC.
Methods: Data pertaining to 224 patients with stage II and III GC who underwent curative gastrectomy were retrospectively analyzed. The total cholesterol-lymphocyte score (TL score) was defined as follows: patients with both low total cholesterol (TC) and total lymphocyte count were allocated a score of 2; patients with only one or none of these biochemical abnormalities were allocated a score of 1 or 0, respectively.
Results: Among the serum lipid indices, low TC was the strongest predictor of cancer-specific survival (CSS; p = 0.001). On multivariate analysis, both low prognostic nutritional index (PNI) (p < 0.001) and high TL score (p = 0.003) were independent prognostic factors. PNI was significantly associated with peritoneal recurrence (p = 0.047), while TL score was significantly associated with locoregional and distant metastasis (p = 0.004 and p = 0.003, respectively).
Conclusions: TL score may facilitate risk stratification of patients based on CSS. TL score plus PNI may help predict the recurrence pattern in patients with stage II and III GC.

Article Synopsis
- This study investigates the relationship between blood lipid levels and disease characteristics in patients with advanced gastric cancer, specifically focusing on how these lipid levels change as the disease progresses.
- Researchers analyzed data from 179 patients with stage III-IV gastric adenocarcinoma, looking at various lipid parameters and their association with factors like age, gender, and metastasis sites.
- The findings suggest that certain lipid levels, such as low total cholesterol and specific changes in LDL-C and VLDL-C, are linked to different metastatic sites, indicating that lipid profiles could be useful biomarkers for predicting where the cancer spreads in patients.
