- W2043312601 abstract "s / Digestive and Liver Disease 46S (2014) e129–e135 e133 management mean costs =16,440$ for patient). HCV etiology had a strong impact on post-LT survival (Hazard Ratio =1.59, 95% CI =1.22–2.09, p=0.0007). Using recent data on SOF efficacy and costs in the base-case scenario, 12-week pre-LT SOF therapy showed a median survival benefit of 3.1 QALYs, an ICER of 35,168$/QALY, and a NHB of 0.9 QALYs, whereas the ICER and NHB of a 24-week therapy were 52,527$/QALY and −0.2 QALY respectively. Conclusions: SOF used as pre-transplant therapy in HCV patients proved to be a cost-effective treatment strategy compared with post-LT SOC therapy. Conflict of interest: None declared.

A pure mucin-secreting form (Mucin-CCA) located either intra or extra-hepatically and a Mixed-CCA form with a peripheral location. We previously identified different subpopulations of CCA CSCs, including epithelial (CD133+, LGR5+, EpCAM+),mesenchymal (CD90+) and quiescent (CD13+) CSCs. Aim: To evaluate the tumorigenic potential of different subpopulation of CSCs isolated from human Mucinand Mixed-CCAs. Methods: CSC subpopulations were immunoselected from human CCA samples (n=18 surgically resected patients) or from primary cultures. The tumorigenic potential of CSC subpopulations was tested either in vitro (spheroid formation), or in xenografts obtained by subcutaneous or intrahepatic injection in normal or cirrhotic (CCL4-induced) livers in SCID mice. In vitro, epithelial CSCs (CD133+, EpCAM+, LGR5+) formed a higher (p 80% (p<0.01). Conclusions: Heterogeneous CSC subpopulations were represented in human CCAs. They generate different type of cancers depending from the type of CSC and the microenvironment. Remarkably, we identified CSC subpopulations capable to reproduce highly invasive and undifferentiated human CCA (CD13+ and CD90+) when injected in mice cirrhotic livers. http://dx.doi.org/10.1016/j.dld.2014.08.013" @default.
