Inflammatory and Nutritional Indices as Prognostic Markers in Elderly Patients With Gastric Cancer

Anticancer Res. 2023 Nov;43(11):5261-5267. doi: 10.21873/anticanres.16728.


BACKGROUND/AIM: Peripheral blood inflammatory and nutritional indices are independent prognostic factors for various cancers. However, as society’s longevity and the demand for surgery in the elderly increase, it remains unclear whether these indices are valuable for patients aged ≥80 years. This study aimed to assess the utility of peripheral blood indices as prognostic markers in elderly patients with gastric cancer (GC).

PATIENTS AND METHODS: This study included 103 elderly patients (aged ≥80 years) who underwent radical gastrectomy at our hospital between 2008 and 2020. Preoperative systemic inflammatory and nutritional indices, including the neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), lymphocyte-monocyte ratio (LMR), and prognostic and nutritional index (PNI), were evaluated. Prognostic evaluation was performed using Kaplan-Meier analysis and Cox regression.

RESULTS: There were no statistically significant differences in NLR, PLR, and LMR regarding overall survival (OS) and relapse-free survival (RFS). However, patients with low PNI had a markedly worse prognosis (3-year OS: 63.9% vs. 81.2%, p=0.002; 3-year RFS: 55.3% vs. 77.6%, p=0.002). Multivariate analysis revealed that male sex and low PNI were independent predictors of OS (p=0.007p=0.003, respectively) and RFS, with only PNI showing significance (p=0.023).

CONCLUSION: Preoperative PNI is an independent prognostic factor for survival in elderly patients with GC who undergo radical gastrectomy.
