Background: This study aimed to clarify the prognostic significance of neutrophil/prealbumin ratio index (NPRI) for overall survival (OS) and recurrence free survival (RFS) of ICC after curative surgery.
Methods: Two-hundred and seventy-six ICC patients who underwent curative resection from December 2006 to April 2017 were recruited and analyzed retrospectively. The correlations between clinicopathological features and NPRI were analyzed. OS and RFS were calculated using Kaplan-Meier curve, and cox univariate and multivariate analyses were used to identify the prognostic factors.
Results: The optimal cut-off value of NPRI determined by ROC curve was 1.74 and the patients were divided into high-value and low-value groups. High-value NPRI was associated with higher risk of postoperative complications (p = 0.035) and longer hospitalization (p = 0.004).Univariate and multivariate cox analyses demonstrated that NPRI was an independent predictor for OS (p = 0.015) and RFS (p = 0.004) in ICC after curative resection. Furthermore, NPRI was also a significant predictor for OS and RFS in different subgroups of ICC, including CA19-9<35U/mL, single tumor, no vascular invasion, no local invasion and AJCC stages I + II.
Conclusions: NPRI was an independent prognostic predictor for ICC after curative resection. It would have high clinical values due to its convenience.
