Gelatin sponge particle used as an embolic agent in transcatheter arterial chemoembolization treatment for primary hepatocellular carcinoma: its current situation in research

Transcatheter arterial chemoembolization(TACE) is one of the most commonly used therapeutic procedures for primary hepatocellular carcinoma(HCC).As an important and easily-available embolic agent,gelatin sponge(Gelfoam) particles have been constantly and widely employed in clinical practice.Various types of embolic agents have been continuously developed and effectively used in TACE for liver cancers.For recent years,great progress has been made in the clinical use of gelatin sponge particles,as the most traditional embolic agent,in the interventional therapeutic field for HCC.This article aims to make a comprehensive review about gelatin sponge.
