    Abstract:
    The elevated platelet-to-lymphocyte ratio (PLR), determined using an easy blood test based on platelet and lymphocyte counts, is reported to be a predictor of poor survival in patients with several cancers. The prognostic role of preoperative PLR in patients with intrahepatic cholangiocarcinoma (ICC) has, until now, been rarely investigated. The purpose of our study was to evaluate the prognostic significance of PLR in a large cohort of ICC patients after hepatic resection. We obtained data from 322 consecutive nonmetastatic ICC patients who underwent hepatectomy without preoperative therapy between 2005 and 2011. Clinicopathological parameters, including PLR, were evaluated. Overall survival (OS) and recurrence-free survival (RFS) were assessed using the Kaplan-Meier method. Using multivariate Cox regression models, the independent prognostic value of preoperative PLR was determined. Our results showed that PLR represents an independent adverse prognostic factor for OS and RFS in ICC patients using univariate and multivariate analyses. The optimal PLR cutoff value was 123 using receiver operating curve analyses. The 5-year OS and RFS rates after hepatectomy were 30.3% and 28.9% for the group with PLR 123 greater, compared with 46.2% and 39.4% for the group with PLR less than 123 (P = 0.0058 and 0.0153, respectively). In addition, high PLR values were associated with tumor size (P = 0.020). Our results suggest that preoperative PLR might represent a novel independent prognostic factor for OS and RFS in ICC patients with hepatic resection.
