TACE Emulsion Versus Suspension

Hepatocellular Carcinoma Clinical Trial

Official title: Lipiodol-based Transcatheter Arterial Chemoembolization for Unresectable Hepatocellular Carcinoma: A Randomized Controlled Trial of Aqueous Cisplatin Emulsion Versus Cisplatin Particle Suspension

Status Completed

Clinical Trial Summary

The aim of the study was to evaluate the safety and efficacy of using the new formulation (Lipiodol-cisplatin suspension) for TACE in the treatment of HCC as compared to the conventional formulation (Lipiodol-cisplatin emulsion). This is a prospective, parallel-group, open-label randomized, phase II study that is conducted in accordance to the Declaration of Helsinki and international standards of Good Clinical Practice, and approved by the institutional review board. Eligible patients were randomized into either a treatment arm of Lipiodol-cisplatin suspension or a control arm of Lipiodol-cisplatin emulsion with a 1:1 ratio.

Clinical Trial Description

Transcatheter arterial chemoembolization (TACE) 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. In Hong Kong, the TACE regimen currently being utilized in the great majority of hospitals is based on an aqueous form of cisplatin (1mg per mL) mixed in a one-to-one ratio by volume with Lipiodol to form a relatively large volume of 40mL emulsion at 20mg cisplatin as the maximum dose. Although TACE with this regimen has been shown to be effective in prolonging overall survival, there is probably room for further improvement because the objective tumor response rate is limited to 39%. One of the approaches to improve the treatment effectiveness of TACE could be to increase the dose of chemotherapeutic agent. In the United States, the most common regimen of chemotherapeutic agent in TACE is the mixture of cisplatin 100mg, doxorubicin 50mg, and mitomycin C 10mg, dissolved in 10ml of water-soluble contrast medium, then emulsified in an equivalent volume of lipiodol to form a 20mL emulsion. A relatively new regimen was introduced, in which a relatively high dose of cisplatin up to 100mg in particle form was given as a suspension in 20mL of Lipiodol, this regimen has been used and found to achieve an improved objective tumor response rate of 51%. ;
