Hepatocellular Carcinoma in Sheep

Radiotherapy for Metastatic Fibrolamellar Hepatocellular Carcinoma

Fibrolamellar hepatocellular carcinoma (FLHCC) is a rare variant of hepatocellular carcinoma (HCC) that commonly affects young individuals without a prior history of liver disease. FLHCC commonly results in a better prognosis than HCC; however, the risk of recurrence and metastatic disease is high. FLHCC is typically treated by primary resection of the tumor with 50-75% cure rates. The use of r...

Liver-Directed Radiotherapy for Hepatocellular Carcinoma.

BACKGROUND The incidence of hepatocellular carcinoma (HCC) continues to increase world-wide. Many patients present with advanced disease with extensive local tumor or vascular invasion and are not candidates for traditionally curative therapies such as orthotopic liver transplantation (OLT) or resection. Radiotherapy (RT) was historically limited by its inability to deliver a tumoricidal dose; ...

Hepatocellular carcinoma in a sheep

At necropsy of a five-year-old sheep, a pear shaped, lobular yellow-brownish mass measuring about 12 ×15 × 20 cm was found to involve the right hepatic lobe. Microscopic examination revealed two trabecularand solid patterns of neoplastic hepatocytes. In solid pattern, there were numerous tumoral giant cells thatcontain one or more large hyperchromatic bizarre-shaped nuclei scattered among clust...

Nonsurgical options for hepatocellular carcinoma: evolving role of external beam radiotherapy.

BACKGROUND Hepatocellular carcinoma (HCC) is the sixth most common cancer worldwide and thus poses a global concern. Its incidence is expected to increase in North America secondary to the increasing incidence of patients who develop hepatitis C. Patients who ultimately develop cirrhosis have an increased risk of developing hepatocellular carcinoma. METHODS The authors focus on nonsurgical th...
