Study Design

Endpoint classification safety/efficacy study
Intervention model single group assignment
Masking open label
Primary purpose treatment
Two treatment sessions at 2 months apart were given and started within 4 weeks after randomization.
Arterial feeders to tumors were identified and catheterized with a microcatheter to a branch supplying a Couinaud segment or subsegmental level for delivery of the therapeutic agent, which was Lipiodol-ethanol mixture at 2:1 ratio by volume for TEA (Lipiodol Ultrafluide, Guerbet, France; Dehydrated alcohol [absolute alcohol], Martindale Pharmaceuticals, United Kingdom). The agents were delivered under fluoroscopic control to completely fill up the vasculature of all tumors. The maximum total volume of Lipiodol-ethanol mixture or cisplatin emulsion to be delivered in one treatment session was 60 mL.

Primary Outcomes

overall survival and treatment-related toxicity
time frame: Overall survival is studied from treatment to death from any cause, for an estimated period of up to 60 months. Treatment-related toxicity is studied up to 3 months after treatment

Secondary Outcomes

Time to progression(TTP)
time frame: Time to progression is studied from treatment to disease progression, for an estimated period of up to 60 months.
Progression free survival(PFS)
time frame: Progression free survival is studied from treatment to disease progression or death from any cause, for an estimated period of up to 60 months.
Tumor response
time frame: Tumor response is studied at 6 months after treatment

Additional Information

Official title A Comprehensive Analysis of Clinical Outcome, Treatment Toxicity and Tumor Response of Transarterial Ablation(TEA) for Unresectable Hepatocellular Carcinoma(HCC)
Principal investigator Simon CH Yu, MD, FRCR
Description Transarterial therapy has been playing an important role in the treatment algorithm for patients with multifocal or large intrahepatic lesions not eligible for surgical resection, transplantation, or local ablative therapy. Among the various options of transarterial therapy including chemoembolization (TACE), bland embolization, radioembolization, and TEA, chemoembolization is the only one that has been proven to be of survival benefits versus best supportive care in randomized controlled trials. TEA is a hybrid of bland embolization and chemical ablation. Utilizing a liquid agent of Lipiodol-ethanol mixture consisting of 33% ethanol by volume, TEA offers complete and long lasting embolization of both the arterioles and portal venules supplying the tumor and could possibly be more effective than particulate embolic agents in tumor vessel embolization. The component of ethanol very likely offers synergistic effect to embolization and causes tumor ablation.
