Activation of the Wnt/β-catenin pathway has been observed in at least 1/3 of hepatocellular carcinomas (HCC), and a significant number of these have mutations in the β-catenin gene. Therefore, effective inhibition of this pathway could provide a novel method to treat HCC. The purposed of this study was to determine whether FH535, which was previously shown to block the β-catenin pathway, could inhibit β-catenin activation of target genes and inhibit proliferation of Liver Cancer Stem Cells (LCSC) and HCC cell lines. Using β-catenin responsive reporter genes, our data indicates that FH535 can inhibit target gene activation by endogenous and exogenously expressed β-catenin, including the constitutively active form of β-catenin that contains a Serine37Alanine mutation. Our data also indicate that proliferation of LCSC and HCC lines is inhibited by FH535 in a dose-dependent manner, and that this correlates with a decrease in the percentage of cells in S phase. Finally, we also show that expression of two well-characterized targets of β-catenin, Cyclin D1 and Survivin, is reduced by FH535. Taken together, this data indicates that FH535 has potential therapeutic value in treatment of liver cancer. Importantly, these results suggest that this therapy may be effective at several levels by targeting both HCC and LCSC.

Patients undergoing LT for HCC had significantly better survival compared to those transplanted for HCC-CC and CC. LT for mixed HCC-CC confers a survival rate similar to selected patients with CC. Efforts should be made to identify HCC-CC patients preoperatively.

CR was an independent predictor of MM and mortality after a PD. Patients requiring PD+CR should be identified pre-operatively, maximally optimized and referred to experienced surgeons at expert centres.

Transfusion, complexity of procedure, and duration of operation were the strongest predictors of unplanned readmissions after liver resection.
