Transcatheter tumor immunoembolization

Transcatheter chemoembolization is clinically used to treat patients with unresectable liver cancer. Our patent application teaches that by addition of a localized immune stimulus to the embolization mixture, we can use the cell death that occurs as a result of this procedure as an “endogenous vaccine” that will stimulate a systemic anti-tumor response. This is based on the fact that immunization in the liver usually results in the induction of a nonproductive immune response, but if appropriate immune stimulators are administered locally, an effective anticancer response will follow that is capable of removing tumor metastasis.
