Objective: To explore the value of preoperative neutrophil-to-lymphocyte ratio (NLR) and γ-glutamyl transpeptidase-to-platelet ratio index (GPRI) for predicting the prognosis of patients with HBV-related intrahepatic cholangiocarcinoma (ICC) after radical resection. Methods: The data of 79 patients who underwent radical resection for HBV-related ICC in the Department of Hepatobiliary Surgery of the First Affiliated Hospital of Xi'an Jiaotong University from January 2010 to December 2018 were retrospectively analyzed. Among them, 48(60.8%) patients were male and 31 (39.2%) patients were female, (56.9±11.2) years old. X-Tile statistical software was used to determine the best cut-off values of NLR and GPRI. The χ2 test was conducted to analyze the relationship between preoperative NLR and GPRI and the clinicopathological characteristics, and the Cox proportional hazard regression model was conducted for multivariate analysis. A nomogram prognostic prediction model was established based on independent risk factors screened by Cox regression model. Results: The best cut-off values of NLR and GPRI were 3.13 and 1.31 determined by the X-Tile software, respectively. With the best cut-off value, 79 patients were divided into NLR≤3.13 group (45 cases) and NLR>3.13 group (34 cases). GPRI≤1.31 group (54 cases) and GPRI>1.31 group (25 cases). Compared with the preoperative NLR ≤3.13 group, the proportion of patients with liver cirrhosis and atrophy, poor pathological differentiation, tumor diameter>5 cm and late TNM stage was significantly increased in the NLR>3.13 group (all P 1.31 group (P=0.025). The postoperative overall survival time of the included patients was 2 to 126 months, with the median survival time being 18 months, and the 1, 3-year overall survival rates were 63.3%, 32.8%, respectively. Multivariate analysis showed that NLR, GPRI, liver cirrhosis and atrophy, and lymphatic metastasis were independent risk factors affecting the overall survival of patients with HBV-related ICC after radical resection (P<0.05). A nomogram prediction model was established based on independent risk factors, with the C-index of 0.750, and the prediction effect was close to the actual survival outcome of the patients. Conclusion: Preoperative peripheral blood NLR and GPRI can be used to predict the prognosis of patients with HBV-related ICC after radical resection.
