BACKGROUND: Despite recent advances in treatment strategies, it is still difficult to cure patients with hepatocellular carcinoma (HCC). Sorafenib is the only approved multiple kinase inhibitor for systemic chemotherapy in patients with advanced HCC. The majority of advanced HCC patients are resistant to sorafenib. The mechanisms of sorafenib resistance are still unknown. METHODS: The expression of molecules involved in the mitogen-activated protein kinase (MAPK) signaling pathway in human hepatoma cell lines was examined in the presence or absence of sorafenib...

Treatment of unresectable recurrent hepatocellular carcinoma (HCC) in patients who recur after resection or orthotopic liver transplantation (OLT) remains a clinical challenge. One option is sorafenib, although little is known about its safety and tolerance in this unique patient population; therefore, we analyzed patients who underwent prior surgical resection and/or OLT and were treated with sorafenib in US cohort of GIDEON registry. In US, 645 patients were enrolled; 553 for intent to treat and 563 for safety...

BACKGROUND: Hepatocellular carcinoma (HCC) is very rare in children and is traditionally associated with a poor prognosis because many patients are not amenable to conventional resection, even in the absence of metastatic disease. For patients with locally advanced or metastatic tumors, conventional chemotherapy appears to offer limited survival benefits. PATIENTS AND METHODS: We report a case series of five consecutive pediatric patients with HCC who were treated with bevacizumab along with conventional platinum-based chemotherapy...

BACKGROUND: In microbeam radiotherapy (MRT), parallel arrays of high-intensity synchrotron x-ray beams achieve normal tissue sparing without compromising tumor control. Grid-therapy using clinical linacs has spatial modulation on a larger scale and achieves promising results for palliative treatments of bulky tumors. The availability of high definition multileaf collimators (HDMLCs) with 2.5 mm leaves provides an opportunity for grid-therapy to more closely approach MRT. However, challenges to the wider implementation of grid-therapy remain because spatial modulation of the target volume runs counter to current radiotherapy practice and mechanisms for the beneficial effects of MRT are not fully understood...

BACKGROUND: Hepatocellular carcinoma (HCC) is the most common liver malignancy worldwide. However, present studies of its multiple gene interaction and cellular pathways still could not explain the initiation and development of HCC perfectly. To find the key genes and miRNAs as well as their potential molecular mechanisms in HCC, microarray data GSE22058, GSE25097, and GSE57958 were analyzed. METHODS: The microarray datasets GSE22058, GSE25097, and GSE57958, including mRNA and miRNA profiles, were downloaded from the GEO database and were analyzed using GEO2R...

BACKGROUND AND PURPOSE: Chromosomal instability is not only a hallmark of cancer, but also an attractive therapeutic target. A diverse set of mitotic kinases maintains chromosomal stability. One of these is monopolar spindle 1 (Mps1), which is essential for chromosome alignment and for the spindle assembly checkpoint (SAC). Pharmacological inhibition of Mps1 has been suggested as a cancer therapeutic; however, despite the existence of a novel Mps1 inhibitor, TC Mps1 12, no such studies have been performed...

Hepatocellular carcinoma (HCC) is the second most common cause of cancer-related deaths worldwide with rapidly growing incidence rates in the USA and Europe. Despite improving surveillance programs, most patients are diagnosed at intermediate to advanced stages and are no longer amenable to curative therapies, such as ablation, surgical resection and liver transplantation. For such patients, catheter-based image-guided embolotherapies such as transarterial chemoembolization (TACE) represent the standard of care and mainstay therapy, as recommended and endorsed by a variety of national guidelines and staging systems...

Sorafenib (Nexavar(®)) is currently the only systemic agent approved for use in hepatocellular carcinoma (HCC). Its approval was based on the results of the pivotal SHARP and Sorafenib Asia-Pacific (AP) trials in Child-Pugh (CP) class A patients with advanced HCC, which showed significantly longer median overall survival (OS) and time to radiological progression (TTP) with sorafenib 400 mg twice daily than with placebo, with no significant between-group difference in the median time to symptomatic progression (TTSP)...

Magnetic resonance imaging (MRI) is the modern gold standard for the noninvasive evaluation of the cirrhotic liver. The combination of arterial phase hyperenhancement and delayed wash-out allows a definitive diagnosis of hepatocellular carcinoma (HCC) in patients with liver cirrhosis or chronic liver disease, without the requirement for confirmatory biopsy. That pattern is highly specific and has been endorsed in Western and Asian diagnostic guidelines. However, the sensitivity of the combination is relatively low for small HCCs...

Adjuvant interferon-α (IFN-α) therapy is used to control certain types of cancer in clinics. For hepatocellular carcinoma (HCC), IFN-α therapy is effective in only a subgroup of HCC patients, therefore identifying biomarkers to predict the response to IFN-α therapy is of high significance and clinical utility. As the induced IFN-stimulated genes (ISGs) expression following IFN-α treatment plays pivotal roles in IFN-α effects, we screened ISGs expression in HCC tissues and found several ISGs were significantly decreased in HCC...

Combined hepatocellular-cholangiocarcinoma (CHC) is a rare tumor with poor prognosis, with incidence ranging from 1.0%-4.7% of all primary hepatic tumors. This entity will be soon renamed as hepato-cholangiocarcinoma. The known risk factors for hepatocellular carcinoma (HCC) have been implicated for CHC including viral hepatitis and cirrhosis. It is difficult to diagnose this tumor pre-operatively. The predominant histologic component within the tumor largely determines the predominant radiographic features making it a difficult distinction...
