NCIt definition : A sterile hemostatic agent composed of purified porcine-derived gelatin. In regional
chemotherapy, absorbable gelatin sponge may be used to embolize arteries in the region
of a tumor in order to block or retard blood flow; this blockage results in a locally
increased concentration of chemotherapeutic agents delivered to the tumor when chemotherapeutic
agents are infused into the embolized arterial circulation upstream of the blockage.;
