BACKGROUND & AIMS: The AFP model was shown to be superior to the Milan criteria for predicting hepatocellular carcinoma (HCC) recurrence after liver transplantation in a French population. Our aim was to test the AFP model in a non-French, post-hepatitic cirrhosis-based population of HCC candidates. METHODS: 574 patients transplanted for HCC in four Italian centers were studied. AFP score was assessed at the last evaluation before liver transplantation (LT). Probabilities of recurrence and survival were estimated by the log-rank test or competing risk analysis and compared according to the AFP model...

A series of novel fatty substituted 4-methyl-2H-chromen-2-one (coumarins) were synthesized by employing cross metathesis, a key step in the synthesis. The antioxidant activities of the title compounds were compared with the commercial antioxidants, namely butylated hydroxy toluene (BHT) and α-tocopherol, glycosidic and other substituted 4-methyl-2H-chromen-2-ones. Among the different 4-methyl-2H-chromen-2-ones, the glycosidic substituted 4-methyl-2H-chromen-2-ones was excellent, while those with aliphatic fatty acid chain and hydroxyl substitutents were good...

The application of cytotoxic chemotherapeutics in cancer therapy has been largely restricted by their lack of selectivity. Despite the existence of numerous targeted delivery systems, it is practically challenging to develop one single system to simultaneously cover tumor-targeted delivery of chemotherapeutics at the tissue, cellular, and subcellular levels. To solve this problem, pH-responsive core-shell structured nanoparticles (CSNPs) were self-assembled in this study to provide triple-stage targeted delivery of doxorubicin (DOX) from the injection site to the nuclei of cancer cells...

This letter discusses the feasibility of continuously monitoring specific mRNA expression responses in a living cell with a probe structured as a fluorescence resonance energy transfer (FRET)-based DNA nano-tweezer (DNA-NT). The FRET-based DNA-NT, self-assembled from three single-stranded DNAs, alters its structure from an open state to a closed state in recognition of a target mRNA, resulting in the closing of the distal relation of previously modified FRET-paired fluorescent dyes and generating a FRET signal...

BACKGROUND/AIMS: Selection of patients with hepa- to-cellular carcinoma for liver transplantation is gen- erally performed according to the so-called Milan cri- teria. The aim of this study was to learn whether, after down-staging loco-regional therapies, patients origi- nally non-fulfilling the MC (Milan-OUT) meet these criteria (Milan-IN). METHODOLOGY: Between January 2000 and December 2008, 172 patients with HCC re- ceived LT at our Department. Of these, 142 were sub- jected to DS before LT...

BACKGROUND: Global deregulation of DNA methylation is one of the crucial causes of hepato cellular carcinoma (HCC). It has been reported that the anti-cancer drug 5-azacytidine (5-AZA) mediates the activation of tumor suppressor genes through passive demethylation by inhibiting DNMT1. Recent evidence suggests that active demethylation which is mediated by ten-eleven translocation (TET) proteins may also be an important step to control global methylation. However, there exists a controversial discussion in which TET proteins are involved in the demethylation process in HCC...

After an initial skepticism, minimally invasive liver surgery (MILS) gained popularity and is nowadays a consolidated option in specialized centers for the surgical treatment of selected patients affected by both benign and malignant liver diseases. Nevertheless, the role of MILS in the surgical treatment of hepato-cellular carcinoma (HCC) developed on the background of chronic liver disease is still a matter of debate. The indications and the current evidences on MILS for HCC are discussed in this paper. MILS being less invasive and harmful for the patients proved to offer a reduction in post-operative morbidity and specific benefits have been highlighted in case of patients affected by HCC and chronic liver disease...

There is increasing evidence to suggest that hepatocellular carcinomas (HCCs) are sustained by a distinct subpopulation of self-renewing cells known as cancer stem cells. However, the precise signals required for maintenance of stemness-like properties of these cells are yet to be elucidated. Here, we demonstrated that the level of oncoprotein osteopontin (OPN) in tumor cells of the edge of bulk tumors was significantly correlated with the clinical prognosis of patients with HCC. OPN was highly expressed in side population fractions of HCC cell lines, as well as in dormant cells, spheroids and chemo-resistant cancer cells, all of which are considered as having stemness-like cellular features...
