Viruses Kill Pancreatic Tumors in Preclinical Model

Image
An intra-tumor injection of a virus prevented further growth of some pancreatic tumors and eradicated others in mouse models of pancreatic ductal adenocarcinoma. However, some tumors continued growing despite this treatment, proving resistant to the viruses. The research is published in the March Journal of Virology.

About 95 percent of pancreatic cancers are pancreatic ductal adenocarcinomas (PDAs). PDA is considered to be one of the most lethal malignancies, resulting in a five year survival rate of only 8-20 percent.

In this study, the researchers, led by Valery Z. Grdzelishvili of the University of North Carolina, Charlotte, tested several species of virus against pancreatic tumors, most notably vesicular stomatitis virus (VSV), a type of virus that is commonly used in the laboratory. Previous studies had demonstrated that some other viruses, including adenoviruses, herpesviruses, and reoviruses, could be used to kill pancreatic cancer cells in some animal models of pancreatic cancer.
