Hepatocellular carcinoma (HCC) is a deadly tumor for which the incidence is increasing in the United States, primarily due to prevalence of hepatitis C infection. An important aspect of the development of HCC is that it occurs in patients who have underlying cirrhosis of the liver, thereby limiting the therapeutic options. There is potential curative treatment for these patients, such as resection of the tumor lesion and liver transplantation, but these treatments are feasible in a small percent of patients only. Furthermore, the majority of the patients with HCC are also not candidates for palliative treatments such as percutaneous ablation of the tumor, chemotherapy or radiation. Additionally, it has been shown that these palliative treatment modalities do not alter survival, and are associated with significant risks. Therefore, there are no treatment options for most patients with HCC. A new theory has emerged in the fight against cancer through inhibition of angiogenesis (development of new blood vessels). The hypothesis being that if there is no blood supply "feeding" the tumor cells cannot divide or survive. One such approach, pioneered in this institution by Drs. George Brewer and Sofia Merajver, is the anticopper approach using the medication tetrathiomolybdate (TM). By creating a mild copper deficiency state, several pathways required for angiogenesis are inhibited. They performed a Phase I trial in which patients with metastatic cancer were treated with TM resulting in decrease tumor vascularity. TM had excellent safety profile in this patient population. HCC is well known to be a hypervascular tumor. An antiangiogenesis approach might provide a novel treatment for this HCC. This is a pilot study of 10 patients with HCC who are not candidates for curative surgical therapy with resection or liver transplantation, nor for ablative techniques. Patients seen in the General Liver clinic and Liver Transplant clinic who have an overall good performance status, with an expected survival of more than 6 months will be enrolled. After an initial evaluation, they will be given 120 mg/day of TM in divided doses for one year. The size and vascularity of the tumor will be evaluated by magnetic resonance imaging (MRI). The primary outcome of this study is to prevent tumor progression.

An ORTHOHEPADNAVIRUS causing chronic liver disease and hepatocellular carcinoma in woodchucks. It closely resembles the human hepatitis B virus.
The type species of the genus ORTHOHEPADNAVIRUS which causes human HEPATITIS B and is also apparently a causal agent in human HEPATOCELLULAR CARCINOMA. The Dane particle is an intact hepatitis virion, named after its discoverer. Non-infectious spherical and tubular particles are also seen in the serum.
The first alpha-globulins to appear in mammalian sera during development of the embryo and the dominant serum proteins in early embryonic life. They reappear in the adult serum during certain pathologic states, primarily hepatocellular carcinoma. They may also be elevated in the amniotic fluid and maternal serum during pregnancy in ANENCEPHALY.
A primary malignant neoplasm of epithelial liver cells. It ranges from a well-differentiated tumor with EPITHELIAL CELLS indistinguishable from normal HEPATOCYTES to a poorly differentiated neoplasm. The cells may be uniform or markedly pleomorphic, or form GIANT CELLS. Several classification schemes have been suggested.
The founding member of the EPH FAMILY RECEPTORS. It was first cloned from an erythropoietin-producing human hepatocellular carcinoma cell line and is highly conserved among many mammalian species. Overproduction of the EphA1 receptor is associated with tumors and tumor cells of epithelial origin. It is also expressed at high levels in LIVER; LUNG; and KIDNEY; which is in contrast to many other members of the Eph receptor that are found primarily in tissues of the nervous system.
