Disclosed are means, methods, and compositions of matter useful for augmentation of a vaccine induced antitumor immune response through immunological targeting of tumor endothelium. In one embodiment a cancer antigen specific vaccine is combined with an endothelial targeting vaccine in a manner to facilitate release of tumor antigens as a result of endothelial destruction. The released tumor antigens serve to amplify immune response induced by the cancer antigen specific vaccine. In one embodiment an endogenous cancer vaccine is utilized as a source of immunization. The endogenous cancer vaccine may be cancer cells induced to die locally such as by means of: hyperthermia, irradiation, oncolytic virus exposure, and embolization.
