Hepatocellular carcinoma (HCC) is a primary cancer of the liver that occurs as a result of chronic liver disease, including cirrhosis and hepatitis B and C infections (Figure 1). Serum alpha-fetoprotien (AFP) levels are elevated early in the disease, and screening of patients with chronic liver disease for AFP has lead to earlier diagnosis of HCC. The test is 40-64% sensitive (the ability to detect disease when disease is truly present) because many HCCs do not produce AFP, but it is 75-91% specific (the ability to rule out disease when disease is truly absent) – an AFP of over 400 mg/mL is considered diagnostic.

Combined Endoglin and VEGF Monoclonal Antibody Therapy in Cancer – Subasinghe Nissanga A Dias, Contributor
Blood vessel formation (angiogenesis) is an important pathologic process in solid tumors. The liberation of vast amounts of vasoendothelial growth factor (VEGF), which attracts endothelial cells, is responsible for angiogenesis. Continue reading
Genspera G-202 – anti-cancer hand grenade
Genspera is a company developing novel prodrugs for the treatment of cancer. In a phase 2 study in patients with hepatocellular carcinoma who have failed treatment with Nexavar (sorafenib), a tyrosine kinase inhibitor that blocks KIT, FLT-3 RET, raf, VEGFR1-3, and PDGF kinases, a doubling of time to progression was seen in patients taking G-202.
