Spots Global Cancer Trial Database for RCT of TAE Simultaneously Combined Thermal Ablation for Large Hepatocellular Carcinoma

Study Description

Brief Summary: This study intends to evaluate the efficacy and safety of Transarterial embolization (TAE) simultaneously combined with thermal ablation for large hepatocellular carcinoma (HCC). Half participants will receive TAE simultaneously combined with thermal ablation and the other half receive TACE sequentially combined with thermal ablation, which is a conventional treatment for HCC patients.

Detailed Description: The treatment method "Transarterial chemoembolization (TACE) sequentially combined with thermal ablation" is recommend for large HCC patients from NCCN Guideline and Chinese guideline "Diagnosis and Treatment of Primary Liver Cancer". The details of this sequential method consist one or more times of TACE followed by thermal ablation at least one month later to make the tumor completely inactivate. The thermal ablations include multiple applicators radiofrequency or microwave ablations. However, this method includes such disadvantages. 1) The limitation of lipiodol dosage in one TACE session is 30ml so that many patients needs more sessions of TACE; (2) Lipiodol and chemical drugs is easy to leak when patients have hepatic arteriovenous fistula. (3) Repeated TACE could cause more serious side effects. (4) Tumors of many patients are still not controlled or grow too large to ablate after TACEs which increases the metastasis risk and affects the efficacy and survival time. However, TAE simultaneously combined with thermal ablation is another combination type which reduce the interval time between two procedures from one month to 1-3 days. TAE removes the chemical drugs and uses embolic agents such as Embosphere to obstruct vessels to enhance the effect of followed ablations. The main aim of reducing interval and remove chemical drugs is to make the tumor completely inactivate in one hospitalization like surgical operation, hoping bringing less side effects, better efficacy and longer survival time. Thus the investigators will launch a prospective, multicenter randomized controlled clinical trial to compare the 3-years overall survival, safety, social and economic benefit of TAE simultaneously combined with ablation and TACE sequentially combined with ablation. The investigators expect to acquire Ia-level evidence-based medical evidence which can be accepted by the clinical guideline, popularizing, demonstrating our therapy.
