The Prognostic Immune and Nutritional Indices Are Independent Prognostic Factors for Esophageal Cancer Patients Who Receive Curative Treatment.
Anticancer Research 2024 May
BACKGROUND/AIM: Recently, the prognostic immune and nutritional index (PINI) was developed and reported to be a promising nutritional and inflammatory prognostic marker. The aim of the present study was to clarify the clinical impact of the PINI for esophageal cancer patients who received curative treatment.
PATIENTS AND METHODS: We conducted a retrospective review of medical records and collected data on consecutive esophageal cancer patients who underwent curative resection at Yokohama City University between 2005 and 2020. The PINI was calculated by dividing the serum ALB concentration (g/dl) by the serum monocyte concentration, both of which were measured before surgery.
RESULTS: A total of 180 patients were included in this study. The cutoff value of the PINI was 3.0 in the present study. The 3- and 5-year overall survival rates were 45.2% and 33.5%, respectively, in the PINI-low subgroup, and 69.1% and 61.8%, respectively, in the PINI-high subgroup. A multivariate analysis demonstrated that the PINI was an independent prognostic factor for overall survival (hazard ratio=2.091, 95% confidence interval=1.287-3.399, p=0.003). Similar results were observed for recurrence-free survival. When comparing the sites of recurrence between the two groups, the incidence of hematological recurrence was significantly greater in the PINI-low subgroup compared to the PINI-high subgroup (46.8% vs. 21.1%, p<0.001).
CONCLUSION: The PINI is a promising nutritional and inflammatory marker for esophageal cancer patients. The PINI might be a useful marker for the treatment and management of esophageal cancer patients.
