Background:
The clinical value of incorporating lipid and inflammatory factors to predict long-term survival in patients with gastric cancer (GC) is unreported. This study aimed to investigate the clinical value of nomograms integrating the Circulating Lipid and Inflammation Risk Score (CLIRS) for predicting the long-term outcome of patients with GC.
Methods:
A retrospective analysis included patients with GC who underwent radical resection at four tertiary medical centers. Patients were divided into training and validation cohorts, with least absolute shrinkage and selection operator regression selecting optimal lipid and inflammatory indicators related to GC prognosis. The CLIRS was developed from six indicators: lymphocyte, triglycerides, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and apolipoprotein B.
Results:
Overall, 2534 patients were studied, including 1910 in the training cohort and 624 in the validation cohort. The CLIRS was an independent risk factor for overall survival (OS; hazard ratio [HR] 1.529, 95% confidence interval [CI] 1.271-1.839; p < 0.001) and disease-free survival (DFS; HR 1.511, 95% CI 1.267-1.801; p < 0.001) in GC patients. The OS nomogram (area under the receiver operating characteristic curve 0.823 vs. 0.785; p < 0.05) and DFS nomogram (AUC 0.804 vs. 0.770; p < 0.05) based on the CLIRS outperformed pTNM stage. High-risk patients had earlier and more sustained recurrence, with higher rates of local, peritoneal, and distant recurrences (p < 0.05).
Conclusions:
The CLIRS, combining circulating lipid and inflammatory factors, is an independent prognostic factor for patients with GC. Nomograms incorporating the CLIRS are superior to pTNM stage in predicting postoperative survival and recurrence in patients with GC.
