Chemoembolization is an interventional radiology procedure designed to reduce blood supply to a tumor and deliver chemotherapy drugs directly to a tumor, while reducing exposure to healthy tissues. This procedure reduces the side effects of chemotherapy while killing cancer cells.
During chemoembolization, an interventional radiologist inserts a catheter into an artery in the groin or wrist and guides the catheter to the tumors in the liver. Chemotherapy is attached to microspheres and injected through a catheter directly into a tumor using image guidance. The chemotherapy drugs are released from the microspheres into the tumor, which blocks the flow of blood to the tumor.
Chemoembolization allows for a higher concentration of chemotherapy drugs to be targeted directly to the cancerous tissue for a longer period of time, without exposing the entire body to the effect of the drugs.
This method of chemotherapy is primarily used for the treatment of liver cancer, and may also be used for the treatment of cancers that have spread to the liver.
