ImmunoCellular Therapeutics Announces Filing Of Key Patent Application Relating To Cancer Stem Cell Technology
ImmunoCellular Therapeutics, Ltd. (OTC: IMUC.OB) (IMUC), a biotechnology company, announced the filing of a provisional U.S. patent application relating to its novel vaccine technology targeting cancer stem cells. The patent application relates to new peptide candidates that may significantly expand the potential target patient population for the company"s cancer stem cell vaccine product candidate, ICT-121. Many cancer therapies are limited by their ability to be used only in patients with certain human leukocyte antigen (HLA) types. Identification of the new peptides for use in IMUC"s vaccine should enable the use of IMUC"s product candidate in patients with many different HLA types. The Company currently has 25 issued or pending patents.

Enhancement Of Pancreatic Cancer On Dynamic CT: Does It Correlate With Angiogenesis And Fibrosis?

Prognosis of pancreatic cancer is poor. Recently, it has been discovered that the grade of tumor angiogenesis is a useful prognostic marker in human cancer, including pancreatic cancer. To establish the grade of tumor angiogenesis by non-invasive imaging may be important clinically. However, there are only a few such reports on pancreatic cancer. The present study, lead by Dr. Hattori and her colleagues from Kanazawa University Graduate School of Medical Science, has recently been published on July 7, 2009 in the World Journal of Gastroenterology. The study investigated the relationship between enhancement on dynamic CT and vascular endothelial growth factor and microvessel density as indicators of angiogenesis, and the extent of fibrosis. Tumors with strong angiogenesis tended to show high enhancement in the arterial dominant phase. On the other hand, tumors with a larger amount of fibrosis showed a negative correlation with the grade of enhancement during the arterial phase. There was a significant correlation between enhancement on conventional dynamic CT and angiogenesis in pancreatic cancer. However, dynamic CT features that are caused by angiogenesis may be modified by the extent of intratumoral fibrosis. For the present, anti-angiogenesis agents are still not approved for the treatment of pancreatic cancer. However, as a preliminary investigation for future clinical application, prediction of the grade of angiogenesis by conventional dynamic multidetector CT, which is most often performed for the diagnosis of pancreatic cancer, would be useful clinically.
