Plain English Summary
Background and study aims
Hepatocellular carcinoma (HCC) is the most common type of liver cancer. It grows a large number of blood vessels that get most of their blood supply from the hepatic artery (one of the main arteries to the liver) . As the rest of the liver tissue gets it blood supply from the portal vein, doctors can treat HCC by cutting off the blood supply to the tumour using a technique called transarterial chemoembolization (TACE). This involves injecting the arteries feeding the liver tumour with a material, often a gelatin sponge which may be soaked with a chemotherapy drug, to block the artery. The sponge traps the chemotherapy inside the liver so that they are concentrated where the tumours are. DEB-TACE is a new way type of TACE whereby special beads containing the chemotherapy drugs are injected into the hepatic arteries and are then slowly released to threat the tumours. It is possible that DEB-TACE is less toxic (harmful) than standard methods and have fewer side effects. This study is looking at whether DEB-TACE is as successful at treating HCC as these other TACE methods.
Who can participate?
Patients aged 18 or over with HCC.
What does the study involve?
All participants are treated with DEB-TACE. They undergo at least 2 sessions of treatment, 2 months apart. All other treatment sessions after this are performed according to results of regular magnetic resonance imaging (MRI) or computed tomography (CT) assessments. All patients are followed up to see how they progress over the next two years. This includes checking for evidence of toxicity both during the DEB-TACE procedure and afterwards, looking at how the tumour responds to the treatment though MRI or CT and assessing for how long it is after treatment before the tumour begins to grow again.
What are the possible benefits and risks of participating?
The potential benefits are to achieve an effective treatment of the disease with much less toxic consequences than other treatment methods. The risks in being submitted to this new treatment are the occurrence of rare, but possible, unexpected side effects.

Intervention
The interventions (Procedures called DEB TACE - Transarterial chemoembolization with drug-eluting beads), were done by a staff member of the interventional radiology team with experience with oncology interventions. Tow vials of the DEB TACE product DC Beads (2 mL, BioCompatibles Ltd., UK) with a diameter of 100 to 300 μm or 300 to 500 μm were loaded, per vial, with 75 mg of doxorubicin hydrochloride (37,5 mg/mL). Through the common femoral artery and using a diagnostic catheter (e.g. Cobra 5F) a microcatheter was placed as near as possible to the vessel irrigating the hepatic tumor. After a secure point was achieved by the tip of the microcatheter, researchers proceeded with the injection of the DC Beads loaded with doxorubicin mixed with contrast media and in a smooth fashion. The endpoint was to administer the whole two DC Beads vials or when flow of the tumor-nourishing artery reduced markedly. Total stasis of the tumor vascularity was avoided so it wouldn’t disturb the subsequent DEB TACE sessions.
The DEB TACE procedures were done at 2-month intervals during the first two sessions. From this point on new DEB TACE sessions were performed on demand accordingly to response in magnetic resonance (MR) and clinical outcome. Tumor response was evaluated with liver dedicated dynamic-enhanced MR of the abdomen and interpreted by body-imaging radiologists. Patients unable to perform MR were schedule to undergo computed tomography (CT). Clinical and laboratory tests were performed before and after each session and during hospitalizations, targeting the evaluation of the toxicity and quantification of adverse effects.
There was no control group.
