The platelet count, as an inflammation marker, is involved in the progress of tumor invasion. However, the prognostic value of platelet counts and the platelet-to-lymphocyte ratio (PLR) has not been investigated in patients with advanced hepatocellular carcinoma (HCC). This study aimed to determine the prognostic value of platelet counts and PLR in HCC patients. A total of 243 ethnic Chinese advanced HCC patients from two major hospitals, not receiving systemic sorafenib, were analyzed retrospectively. The prognostic value of differential blood cell counts and PLR for overall survival (OS) was determined by integrating the Cancer of the Liver Italian Program (CLIP) score system and model for end-stage liver disease by using a stepwise model of multivariate Cox regression. The Kaplan-Meier method and receiver operating characteristic (ROC) curves were utilized accordingly. PLR was confirmed to be an independent predictor for OS (p < 0.01), while the remaining parameters had no predictive value. Then, advanced HCC patients were dichotomized into two groups based on the PLR value (≤111.23 or >111.23), according to ROC analysis. Patients with a high PLR had a lower 3-month survival rate (37.6 vs. 57.6%) compared with patients with a low PLR. PLR was associated with aggressive malignant behavior, characterized by distant metastasis and portal vein thrombosis. Additionally, PLR was not associated with the CLIP score and Child-Pugh grade. PLR was identified as an independent prognostic factor for advanced HCC patients not receiving systemic sorafenib; the predictive ability of PLR partially relies on its association with the aggressive nature of HCC.

Few studies investigated the prognosis of patients with advanced hepatocellular carcinoma (aHCC). This study was aimed to determine the prognostic value of differential blood cell counts including blood white cells, neutrophil, lymphocyte, neutrophil-lymphocyte ratio (NLR), and platelet in patients with aHCC. A total of 205 ethnic Chinese aHCC patients receiving non-systematic sorafenib were analyzed retrospectively. The prognostic value of differential blood cell counts and NLR for overall survival (OS) was determined by integration into Cancer of the Liver Italian Program (CLIP) score system using backward elimination model of multivariate Cox regression. As a result, NLR was confirmed to be an independent predictor for OS (p = 0.001) with the rest parameters presented negative results. Then, aHCC patients were dichotomized into two groups according to NLR values ≤ 2.43 or >2.43. Patients with low NLR presented lower CLIP score and higher 6-month survival rate (56.1 vs 25.9%) compared with patients with high NLR level. Besides, low NLR level was associated with favorable prognostic factors such as lower α-fetoprotein, alkaline phosphatase, and total bilirubin, as well as decreased incidence of ascites, portal vein thrombosis, and metastasis. Besides, low NLR level was associated less white cells and neutrophil granulocytes, as well as more lymphocyte. In summary, the present study firstly indentified NLR as an independent prognostic factor in aHCC patients receiving no systematic sorafenib.
