Abstract
BACKGROUND: It was reported that systemic immune inflammation index (SII) was related to poor prognosis in a variety of cancers. We aimed to investigate the ability of the prognostic predictors of SII in patients with intrahepatic cholangiocarcinoma (iCCA) undergoing liver transplantation (LT). METHODS: The 28 iCCA patients who underwent LT at our hospital between 2013 and 2018 were reviewed. Kaplan-Meier survival curves and Cox regression analyses were used to evaluate the prognostic significance of SII. Patients were divided into the high and low SII groups according to the cut-off value. RESULTS: The 1-, 3-, and 5-year OS rates were significantly lower in the high SII group (85.7%, 28.6%, and 21.4%, respectively) than in the low SII group (92.9%, 71.4%, and 57.2%, respectively; P = 0.009). The 1-, 3-, and 5-year RFS rates were, respectively, 57.1%, 32.7%, and 21.8% in the high SII group and 85.7%, 61.1%, and 61.1% in the low SII group (P = 0.021). SII ≥ 447.48 × 109/L (HR 0.273, 95% CI 0.082-0.908; P = 0.034) was an independent prognostic factor for OS. CONCLUSIONS: Our results showed that SII can be used to predict the survival of patients with iCCA who undergo LT.
