  •   Objective  To study the relationship between preoperative neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) with the clinicopathological characteristics and T staging of hilar cholangiocarcinoma (HC).  Methods  The data of patients with HC were analyzed retrospectively. The receiver operating characteristic (ROC) curve was used to determine the best cut-off values of NLR and PLR. Statistical analysis of preoperative NLR and PLR and HC pathological characteristics and the relationship between T staging and the predictive value of T staging.  Results  The ROC curve was used to determine the best cut-off value: high-NLR group (NLR>4.12, 56 cases), low-NLR group (NLR≤4.12, 44 cases), high-PLR group (>184.56, 48 cases) and low-PLR group (≤184.56, 52 cases). Univariate analysis showed that preoperative NLR was correlated with tumour location and T stage (all P < 0.05) and had no correlation with gender, age, degree of differentiation and tumour size (all P > 0.05). Preoperative PLR was correlated with T stage, tumour size and lymph node metastasis (all P < 0.05) and had no correlation with gender, age, degree of differentiation and tumour location (all P > 0.05). Multivariate analysis showed that preoperative NLR was associated with T staging (OR=2.999, P=0.026) and tumour location (OR=0.346, P=0.032). Preoperative PLR was related to T stage (OR=3.635, P=0.007) and tumour size (OR=1.728, P=0.031), but not to lymph node metastasis (P > 0.05). The ROC curve areas of NLR and PLR before surgery were 0.811 and 0.794, respectively, which have predictive value for T staging.  Conclusion  Preoperative NLR and PLR are simple and practical detection indicators that can be used to evaluate the pathological characteristics of HC before surgery and have predictive value for T staging.
