(PHILADELPHIA) A combination of sorafenib and vitamin K had an effect in vitro on both human pancreas cancer and hepatocellular carcinoma, according to researchers from the Kimmel Cancer Center at Jefferson. Data from the two studies were presented at the AACR 100th Annual Meeting 2009 in Denver. (Abstract #5470 and #5483)
Vitamin K1 or vitamin K2, plus sorafenib (Nexavar) each have shown activity against the growth of human cancer cells by inhibiting the extracellular signal-regulated kinase (ERK) pathway according to Brian Carr, M.D., Ph.D., a professor of Medical Oncology at the Jefferson Medical College of Thomas Jefferson University. ERK plays a major role in cell growth of cancers.
Although sorafenib has demonstrated success at extending survival in patients with hepatocellular carcinoma (HCC, or primary liver cancer), hand-foot syndrome is a common adverse effect that affects approximately 20 percent of patients who receive the drug. It typically manifests as painful sores on the soles of patients’ feet that can prevent the patients from walking, Dr. Carr said. Profound tiredness and weight loss is also seen in at least 30 percent of patients.
