Adv Healthc Mater 2022 Jun 24:e2200579. Epub 2022 Jun 24.

Shanghai Institute of Transplantation, Shanghai, 200127, China.

Hepatocellular carcinoma (HCC) is the most common form of primary liver cancer and remains a global health challenge. Small interfering RNA (siRNA) is a promising therapeutic modality that blocks multiple disease-causing genes without impairing cell structures. However, siRNA therapeutics still have off-target proportion and lack effective quantitative analysis method in vivo. Read More

Liver function monitoring in Fontan-procedure patients: audit of current practice across South Wales.

Br J Cardiol 2021 2;28(3):29. Epub 2021 Jun 2.

Consultant Cardiologist University Hospital of Wales, Cardiff & Vale University Health Board, Heath Park Way, Cardiff, CF14 4XW.

The Fontan procedure provides a palliative surgical repair for complex congenital heart disease, but it is associated with many long-term problems, including liver cirrhosis, and hepatocellular carcinoma. The current suggestion from international guidance is that end-organ surveillance should be carried out, with a particular focus on regular blood tests and imaging for liver function. In this study, retrospective analysis was performed on adult patients who had previously had a Fontan operation performed to determine the regularity of end-organ surveillance in regards to their liver function covering the three calendar years from 2016 to 2018, and the first six months of 2019.

Disseminated Primary Uterine Hepatoid Adenocarcinoma with α-Fetoprotein Production Demonstrated on F-FDG PET/CT.

Diagnostics (Basel) 2022 Jun 12;12(6). Epub 2022 Jun 12.

Department of Oncology, Rigshospitalet, Copenhagen University Hospital, 2100 Copenhagen, Denmark.

We present the F-Fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) findings in a 57-year-old woman with post-menopausal bleeding diagnosed with hepatoid adenocarcinoma (HAC) with a primary tumour in the uterine corpus and a highly elevated level of serum-α-fetoprotein (S-AFP) at presentation. HAC is a variant of adenocarcinoma with hepatic differentiation representing a heterogeneous group of neoplasms that morphologically and immunphenotypically resemble hepatocellular carcinoma (HCC) but are of extrahepatic origin. Microscopically, they are usually poorly differentiated adenocarcinomas proliferating in solid sheets or in a trabecular or cord-like arrangement. Read More

Loco-regional treatment of hepatocellular carcinoma: Role of contrast-enhanced ultrasonography.

World J Hepatol 2022 May 7;14(5):911-922. Epub 2022 Apr 7.

Department of Radiology, University Hospital "Paolo Giaccone", Palermo 90127, Italy.

Hepatocellular carcinoma (HCC) is one of the few cancers for which locoregional treatments (LRTs) are included in international guidelines and are considered as a valid alternative to conventional surgery. According to Barcelona Clinic Liver Cancer classification, percutaneous treatments such as percutaneous ethanol injection, radiofrequency ablation and microwave ablation are the therapy of choice among curative treatments in patients categorized as very early and early stage, while transcatheter arterial chemoembolization is considered the better option for intermediate stage HCC. A precise assessment of treatment efficacy and surveillance is essential to optimize survival rate, whereas residual tumor requires additional treatment. Read More

Polyisocyanide hydrogels with tunable nonlinear elasticity mediate liver carcinoma cell functional response.

Acta Biomater 2022 Jun 16. Epub 2022 Jun 16.

Key Laboratory of Hebei Province for Molecular Biophysics, Institute of Biophysics, School of Science, Hebei University of Technology, Tianjin 300401, PR China. Electronic address:

Hepatocellular carcinoma development is closely related to the changes in tissue mechanics induced by excess collagen deposition and crosslinking, which leads to liver fibrosis and malignant progression. The role of matrix stiffness has been widely assessed using various linearly elastic materials. However, the liver, like many soft tissues, also exhibits nonlinear elasticity by strain-stiffening, allowing cells to mechanically interact with their micromilieus which has attracted much attention in cellular processes recently.

Front Bioeng Biotechnol 2022 30;10:914979. Epub 2022 May 30.

IBiTech-Biommeda, Department of Electronics and Information Systems, Ghent University, Ghent, Belgium.

Hepatocellular carcinoma (HCC) is the most common form of primary liver cancer. At its intermediate, unresectable stage, HCC is typically treated by local injection of embolizing microspheres in the hepatic arteries to selectively damage tumor tissue. Interestingly, computational fluid dynamics (CFD) has been applied increasingly to elucidate the impact of clinically variable parameters, such as injection location, on the downstream particle distribution.
