AIMS: Glypican-3(GPC3) expression is correlated with poor prognosis and progression in hepatocellular carcinoma (HCC). HCC progression can be associated with the differentiation status of tumor cell before malignant transformation. Our aim was to investigate the dynamic expression of GPC3 during tumor cells differentiation and to explore the role and theoretical significance of GPC3 in malignant essence of HCC. METHODS: The expressions of tissue GPC3 and alpha-fetoprotein (AFP) were detected by immunohistochemical staining...

Selective internal radiation therapy (SIRT) of hepatocellular carcinoma has been introduced at Aarhus University Hospital. 90Y-microspheres are implanted in the tumour by catheterization of the tumour feeding liver artery. Pretreatment angiography and test treatment using 99mTc-labelled particles followed by scintigraphy ensure a feasible and effective treatment. Post-treatment imaging of radiation from 90Y visualize the localization of microspheres. Currently, SIRT is also applied for liver metastases of neuroendocrine tumours...

BACKGROUND: The incidence of HCC continues to increase dramatically worldwide. Liver transplantation (LT) is now standard and optimal treatment for patients with HCC in the setting of cirrhosis, but only for tumors within Milan criteria (MC). In patients presenting beyond Milan, locoregional therapy (LRT) may downstage to within-Milan for consideration of LT. While controversial, the current study aims to evaluate the outcomes of LT in patients presenting with advanced stage HCC who underwent downstaging and compare to patients who meet Milan criteria at presentation...

BACKGROUND: Hepatocellular carcinoma (HCC) is a leading cause of death worldwide. Among the surgical and nonsurgical treatments available, radiofrequency ablation (RFA) and sorafenib have been shown to have efficacy. There is little evidence whether combination of these therapies would have additional benefits. METHODS: In a mouse model of HCC, effects of sorafenib were determined by tumor size, RFA-induced necrosis area (triphenyltetrazolium chloride staining), microvascular density (MVD; 4',6-diamidino-2-phenylindole and anti-CD31 antibody staining), and tumor perfusion (magnetic resonance imaging)...

Sorafenib is thus far the only systemic treatment for hepatocellular carcinoma (HCC) based on the results of two randomized controlled trials performed in Western and in Eastern countries, despite a poor response rate (from 2% to 3.3%) following conventional evaluation criteria. It is now recognized that the criteria (European Association of the Study of the Liver criteria, modified response evaluation criteria in solid tumors) based on contrast enhanced techniques (computed tomography scan, magnetic resonance imaging) aimed to assess the evolution of the viable part of the tumor (hypervascularized on arterial phase) are of major interest to determine the efficacy of sorafenib and of most antiangiogenic drugs in patients with HCC...

The diagnosis of hepatocellular carcinoma (HCC) is based on imaging studies particularly in high-risk patients without histologic confirmation. This study evaluated the prevalence and characteristics of false-positively diagnosed HCC in a liver resection cohort for HCC. A retrospective review was performed of 837 liver resection cases for clinically diagnosed HCC between 2005 and 2010 at our institute. High-risk patients with tumors > 1 cm with one or two image findings consistent with HCC and tumors < 1 cm with two or more image findings consistent with HCC with persistently increased serum alpha-fetoprotein (AFP) levels above the normal range with underlying inhibited hepatitis activity underwent liver resection...

PURPOSE: Selective-internal-radiation-therapy (SIRT) and transarterial-chemoembolization (TACE) are commonly used for treatment of liver tumors. The use of TACE, which is macroembolic, prior to SIRT may cause hemodynamic changes in tumor vasculature that impair yttrium-90 (90Y) microsphere delivery to the targeted lesions. This work aims to quantify dosimetric tumor coverage using 90Y positron emission tomography (PET) dosimetry after SIRT alone compared to TACE followed by SIRT. METHODS: A total of 40 consecutive hepatocellular carcinoma (HCC) SIRT patients who had a post-SIRT 90Y PET/CT scan were evaluated...

Intrahepatic lesions of hepatocellular carcinoma (HCC) have been controlled by significant advances in treatment using loco-regional therapies, including, surgery, ablative therapy, catheter-based chemotherapy, and embolization. Consequently, the number of patients with extrahepatic metastatic lesions has increased. Their prognosis remains poor with approximately <1 year of survival from the time of diagnosis. A molecularly targeted drug, sorafenib, have been used to treat extrahepatic lesions and shown the prolonged survival time...

Epidermal growth factor receptor mutant III (EGFRvIII) is exclusively expressed in tumors, such as glioblastoma, breast cancer and hepatocellular carcinoma, but never in normal organs. Increasing evidence suggests that EGFRvIII has clinical significance in glioblastoma prognosis due to its enhanced tumorigenicity and chemo/radio resistance, thus the development of an imaging approach to early detect EGFRvIII expression with high specificity is urgently needed. To illustrate this point, we developed a novel anti-EGFRvIII monoclonal antibody 4G1 through mouse immunization, cell fusion and hybridoma screening and then confirmed its specificity and affinity by a serial of assays...
