About

Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer. This type of cancer may be "hypervascular". Hypervascular means there is an increased number or concentration of blood vessels. These blood vessels get their blood supply from the hepatic artery, while the non-tumor liver tissue gets blood supply from the portal vein. Therefore, blockage of the hepatic artery to cut off the blood supply to the tumor is possible without affecting the normal liver.

This research protocol will study chemoembolization using radiopaque beads loaded with a chemotherapy drug called doxorubicin. Chemoembolization is a procedure in which the blood supply to a tumor is blocked after anticancer drugs are given in blood vessels near the tumor. In this study, the anticancer drug, doxorubicin, is attached to small beads that are injected into an artery that feeds the tumor. The radiopaque beads (RO beads) are visible on imagining scans (X-rays) so that the Interventional Radiologist performing the chemoembolization procedure can see the location of the beads in the tumor during and after the procedure. The visibility of the beads allows the interventional radiologist to confirm where the beads loaded with doxorubicin have been delivered in the tumor; this in theory could help to improve the efficiency of embolization and plan the next course of treatment. In addition to the embolization, the beads elute a sustained dose of doxorubicin locally to the tumor site as a second effect.

Full description

The usual treatment for HCC is to perform a procedure to the tumor known as Transarterial Chemo-Embolization (TACE). TACE has been approved and used worldwide for over 10 years.

Transarterial means that the treatment is delivered using a catheter inserted into the hepatic artery. Embolization is a treatment that blocks or slows down the blood supply to tissues. This procedure is performed to block the flow of blood to a tumor, so the cancer cells die because the oxygen supply is interrupted. When the material used to block the blood supply also delivers a chemotherapy drug to the tumor, it is called chemoembolization. The most commonly used material for chemoembolization are drug-eluting beads (DEBs) that are loaded with a chemotherapy drug (doxorubicin). These beads are not visible, during the procedure, on the imaging (scanner, ultrasonography or MRI) while injected into the tumor. The consequences of the blood flow interruption are visible on imaging (CT, MRI) in the weeks following treatment (tissue infarction/tumor necrosis).

This study uses the LC Bead LUMI™ radiopaque beads (RO beads). The difference is that RO Beads are visible with X-Ray imaging (scanner, fluoroscopy). This is important because it means that the Interventional Radiologist is able to verify, during the procedure, where the beads have been delivered to the tumor. The Interventional Radiologist will identify the blood supply to the tumor, and then inject the LC Bead LUMI™ loaded with doxorubicin and a compatible contrast agent into the blood vessels that supply the liver tumor. These RO beads block the blood vessel, starve the tumor of nutrients and deliver a slow release of the doxorubicin.

Many of the tests, investigations and procedures that will be requested as a part of the study may be the same as what is routinely done in the diagnosis and treatment of HCC. These tests will be used to determine if you are eligible to participate in this study and receive the LC Bead LUMI™ loaded with doxorubicin. Some of the study assessments are done to evaluate the safety and efficacy of the treatment procedure and others will be done for research purposes.

During the study, the tests and evaluations will be scheduled with normally occurring appointments, when possible; to reduce the number of visits the patient needs to make to the study center. Study visits for tumor response evaluation occur at one month after the first treatment then every 3 months for 2 years then every 6 months.

The information obtained during your visits will help your study doctor determine what choices you have for the next best course of action in treating your cancer. Options may include; repeat the study treatment, propose another alternative treatment or to continue the follow-up.
