TACE Using Idarubicin Versus Doxorubicin Chemoemulsion in Patients with Hepatocellular Carcinoma

Официальное название

Transarterial Chemoembolization Using Idarubicin Versus Doxorubicin Chemoemulsion in Patients with Hepatocellular Carcinoma (IDADOX)

Обзор

Little is known about whether the types of chemotherapeutic agents affect the efficacy of transarterial chemoembolization in patients with hepatocellular carcinoma. Although doxorubicin is the most commonly-used chemotherapeutic agent in the world, idarubicin is recently in the spotlight after promising results of the in vitro and prospective single-arm studies. On the other hand, there are many reports showing that the type of chemotherapeutic agents does not significantly alter the efficacy of transarterial chemoembolization. This is a randomized-controlled trial to show the non-inferiority of idarubicin compared to doxorubicin in patients with hepatocellular carcinoma who receive transarterial chemoembolization as the first-line treatment.

Подробное описание

Eligible patients will be randomly allocated either in the IDA-cTACE or DOX-cTACE group, and the randomization can be stratified by Child-Pugh class. Each patient will be treated by conventional chemoembolization using a microcatheter and chemoemulsion. For the chemoemulsion preparation method, 10 mg of idarubicin powder (IDA-cTACE) or 50 mg of doxorubicin powder (DOX-cTACE) will be dissolved by 2.5 mL of iodinated contrast media, and then mixed with 10 mL of iodized poppy seed oil (Lipiodol; Lipiodol Ultrafluid, Guerbet, France). The amount of chemoemulsion administered to each patient will be determined by an operator regarding tumor size, vascularity, etc. Additional embolization will be performed using calibrated gelatin sponge particles usually 100-350 µm until the arterial flow is almost stopped. Afterwards, Patients will be evaluated at 1, 3, and 6 months after the initial treatment, but the follow-up can be individualized at the discretion of hepatologists or hepatic surgeons blinded to the treatment allocation. In cases of residual or recurred tumor, additional treatments will be determined by the blinded hepatologists or hepatic surgeons. Once a patient with residual or recurred tumor receives repetitive TACE, the same drug (idarubicin or doxorubicin) used at the initial TACE will be used for re-treatments.

Вмешательства

• Процедура IDA-TACE
  Stable chemoemulsion will be produced by dissolving 10 mg of idarubicin powder (Zavedos; Pfizer, New York, NY, USA) in 2.5 mL of an iodinated contrast agent. This solution will then be mixed with 10 mL of iodized oil (Lipiodol Ultrafluid; Guerbet, Villepinte, France) using a three-way stopcock. This chemoemulsion will be prepared in aliquots (0.8 mL of chemoemulsion in each 1 mL syringe) and injected until the embolization endpoint is achieved.
• Процедура DOX-TACE
  Stable chemoemulsion will be produced by dissolving 50 mg of doxorubicin powder (Adriamycin RDF; Ildong Pharmaceutical, Seoul, Republic of Korea) in 2.5 mL of an iodinated contrast agent. This solution will then be mixed with 10 mL of iodized oil (Lipiodol Ultrafluid; Guerbet, Villepinte, France) using a three-way stopcock. This chemoemulsion will be prepared in aliquots (0.8 mL of chemoemulsion in each 1 mL syringe) and injected until the embolization endpoint is achieved.
