Genetic Determinants in a Critical Domain of NS5A Correlate with Hepatocellular Carcinoma in Cirrhotic Patients Infected with HCV Genotype 1b
2021
HCV is an important cause of hepatocellular carcinoma (HCC). HCV NS5A domain-1 interacts with cellular proteins inducing pro-oncogenic pathways. Thus, we explore genetic variations in NS5A domain-1 and their association with HCC, by analyzing 188 NS5A sequences from HCV genotype-1b infected DAA-naïve cirrhotic patients: 34 with HCC and 154 without HCC. Specific NS5A mutations significantly correlate with HCC: S3T (8.8% vs. 1.3%, p = 0.01), T122M (8.8% vs. 0.0%, p <
Modeling cost-effectiveness and health gains of a âuniversalâ versus âprioritizedâ hepatitis C virus treatment policy in a real-life cohort
2017
We evaluated the cost-effectiveness of two alternative direct-acting antiviral (DAA) treatment policies in a real-life cohort of hepatitis C virusâinfected patients: policy 1, âuniversal,â treat all patients, regardless of fibrosis stage; policy 2, treat only âprioritizedâ patients, delay treatment of the remaining patients until reaching stage F3. A liver disease progression Markov model, which used a lifetime horizon and health care system perspective, was applied to the PITER cohort (representative of Italian hepatitis C virusâinfected patients in care). Specifically, 8,125 patients naive to DAA treatment, without clinical, sociodemographic, or insurance restrictions, were us…
Long-term evolution of hepatocellular adenomas at MRI follow-up
2021
Background Hepatocellular adenomas (HCAs) are rare benign liver tumors. Guidelines recommend continued surveillance of patients diagnosed with HCAs, but these guidelines are mainly based on small studies or expert opinion. Purpose To analyze the long-term evolution of HCAs, including solitary and multiple lesions, and to identify predictive features of progression with MRI. Materials and Methods In a retrospective study, patients diagnosed with pathologically proven solitary or multiple HCAs between January 2004 and December 2015 were included; β-catenin-mutated HCAs and HCAs with foci of malignancy were considered to be at risk for progression. MRI examinations were analyzed, and tumor evo…

Transarteriālas ķīmijterapijas pielietošana aknu audzēju ārstēšanā
2016
Ievads: Transarteriāla ķīmijembolizācija ar medikamentus izdalošām mikrosfērām (DEB-TACE) ir audzēja apasiņojošo artēriju oklūzija digitālās subtrakcijas angiogrāfijas laikā, izmantojot mikrosfēras piesūcinātas ar ķīmijembolizācijas materiālu, kas pēc ievades pagarina saskares laiku starp audzēja šūnām un ķīmijterapijas medikamentiem. DEB-TACE tiek plaši pielietota hepatocelulārās karcinomas (HCC) paliatīvajā ārstēšanā, kad rezekcija vai ablācija nav iespējama. DEB-TACE tiek izmantota arī citu hipervaskulāru nerezicējamu aknu audzēju, piemēram, holangiokarcinomas, kolorektālu aknu metastāžu ārstēšanā. Optimāli kandidāti ārstēšanai ir Child-Pugh A un B klases pacienti ar lielu vai multifokāl…
Cationic SLN for siRNA and DNA plasmid delivery in hepatocellular carcinoma
2014
Hepatocellular carcinoma (HCC) is the sixth most common cancer worldwide and the third leading cause of cancer-related deaths. For the treatment of HCC several drugs are under development, but the only one with proven survival benefit is sorafenib. This agent is a multikinase inhibitor that blocks Raf signaling and VEGF, PDGF and c-Kit. It has antiproliferative and antiangiogenic activity and delays tumor progression [1,2]. Moreover, systemic tumor-targeted gene delivery is attracting increasing attention as a promising alternative to conventional therapeutic strategies. At this purpose a large number of viral and non-viral vectors have been studied and applied as systems of stable transfec…
Possible mechanisms of Raf-1 Kinase Inhibitor Protein down-regulation in hepatocellular carcinoma

Induction of Apoptosis and Chemosensitization by the Histone Deacetylase Inhibitor Trichostatin in Hepatocellular Carcinoma Cells: Molecular Analysis…
2011
The mRNA and protein levels of RKIP are reduced and those of YY1 increased in clinical HCC. Loss, mutation, or promoter hypermethylation of the RKIP gene may not account for the downregulation of RKIP in HCC. Histone deacetylation can silence gene expression and play a significant role in hepatocarcinogenesis. The histone deacetylase inhibitor (HDACI) trichostatin induced cell growth inhibition and proapoptotic effects in HA22T/VGH and HepG2 HCC cells; it also exhibited synergy with doxorubicin. Treatment with trichostatin caused histone hyperacetylation and down- or upregulated expression of different genes (such as β-catenin, cyclin D1, hTERT, XIAP, and IL-6). These changes might, at leas…
