C-C chemokine hepatocellular carcinoma motif ligand 5-deficiency promotes hepatocellular carcinoma progression by affecting B cell recruitment.

Objective: To evaluate the expression of C-C motif chemokine ligand 5 (CCL5) in hepatocellular carcinoma (HCC) and to explore its role in regulating the immune microenvironment and the related mechanism in tumor immunity.

Methods: The mRNA expression level of CCL5 in HCC and adjacent non-cancerous tissues was measured by quantitative polymerase chain reaction and the protein expression was examined by immunohistochemistry. Serum CCL5 expression was measured by an enzyme-linked immunosorbent assay (ELISA).

Validation of a criteria-specific long-term survival prediction model for hepatocellular carcinoma patients after liver transplantation.

The aim of this study was to validate a criteria-specific long-term survival prediction model (MHCAT) in a large cohort of hepatocellular carcinoma (HCC) patients after liver transplantation (LT) in China. Independent risk factors in MHCAT were retrospectively analysed for HCC patients recorded in the China Liver Transplant Registry. Survival predictions for each patient were calculated using MHCAT scores and the Metroticket formula separately, and the prediction efficacy of MHCAT and Metroticket was compared using the area under ROC curve (c-statistic).
