Oncolytic vaccinia virus in combination with radiation shows synergistic antitumor efficacy in pancreatic cancer
Menée in vitro et à l'aide de xénogreffes de cancer du pancréas sur un modèle murin, cette étude montre qu'un vaccin oncolytique (GLV-1h151) et une radiothérapie peuvent avoir un effet synergique contre les cellules tumorales
Combining oncolytic viruses with conventional therapy such as radiation is an innovative option for pancreatic cancer. We demonstrated that combination of GLV-1h151 and radiation yielded a synergistic cytotoxic effect, with the greatest effect achieved in the AsPC-1cell line. Combination treatment significantly increased apoptosis compared with either single treatment or the control group. In mice bearing human pancreatic tumor xenografts, combination treatment resulted in significantly enhanced inhibition of tumor growth. No evidence of toxicity was observed in mice. These results indicate that the combination of GLV-1h151 and radiation has great potential for translation into clinic practice.
