Detailed Description
Specific Aims:
The aim of the current study is to compare TACE and RFA combination therapies with RFA mono-therapy by using simultaneous multiple electrodes and switching RF controller in the treatment of uni-lobar HCC of 3.1 to 7cm. The rate of complete necrosis (CN), technique success, sessions to achieve CN, local tumor progression, survival rate and major complications will be analyzed.
Background:
HCC is 4th mostly common malignancy worldwide and the leading cause of cancer-death in Taiwan.
Surveillance programs can detect HCC at early stage. Surgical resection, liver transplantation and local ablation are currently considered as curative treatment modalities for early stage HCC. However, only 10-30% of early stage HCC is suitable for resection due to poor liver reserve, co-morbidity and shortage of liver donor. Therefore, local ablation plays an important role in the treatment of unresectable or resectable early-stage HCC. Among the various local ablative modalities, radiofrequency ablation (RFA) has been proved to be a curative treatment with minimal invasiveness and high efficacy for small HCC that is generally defined as maximal diameter no larger than 3cm. RFA can achieve a rate of complete necrosis as 80-100% in small HCC. However, the rate will drop to 71% in HCC of 3.1-5cm and 25% for HCC > 5cm。 The difference is due to the relative hypervascularity for the bigger tumor and it will induce heat sink that leading to less effect of ablation. Therefore, transcatheter chemoembolization (TACE) before RFA may reduce the vascularity and enhance the effect of subsequent RFA. Moreover, pre-RF TACE will reduce the tumor size and the subsequent RFA to unembolized viable tumor will be more effective than RFA alone. In retrospective studies, Kitamoto M et al showed that tumor necrosis diameter was larger in combine TACE and RFA compared to RFA monotherapy; Yamakado K et al showed that combine TACE and RFA in HCC (maximal diameter up to 12 cm) achieved 100% complete necrosis, 0% local recurrence rate and 93% of 2-year survival rate. Nevertheless, only one randomized trial in intermediate size HCC (3-5cm in diameter) showed that combine TACE and RFA achieved a significant higher rate of technique success, fewer treatment sessions and lower local recurrence but non-significant in 3-year survival rate. Therefore, based on the limited studies, combine TACE and RFA may achieve better effects than RFA mono-therapy in HCC larger than 3cm. However, repeat TACE may induce some complications such as HBV reactivation, hepatitis or even liver decompensation. Moreover, novel RFA using simultaneous multiple RFA probes with switching RF controller may achieve a better effects and shorter ablation time than sequential RFA with single electrode. Thus, is it still necessary using TACE and RFA combination therapies for HCC > 3cm when application of novel switching RF controller? aim of the current study is to conduct a RCT comparing combine TACE and RFA compared to RFA mono-therapy by using simultaneous multiple electrodes and switching RF controller in uni-lobar HCC of 3.1-7cm. The rate of complete necrosis, sessions to achieve CN, primary technique effectiveness (i.e. achievement of complete necrosis after maximum of 3 treatment sessions), local tumor progression, survival rate and major complications will be analyzed.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
ACTIVE_COMPARATOR: TACE+ RFA
This arm will be conventional TACE(Transcatheter Arterial Chemoembolization) plus RFA(radiofrequency ablation. use intra-injection of lipiodol mized with doxorubicin when the catheter was placed in the superselective location very close to the tumor. |
traditional TACE, conventional TACE
Other Names:
TACE will be done according to the current method in our center.
We use intra-injection of lipiodol mized with doxorubicin when the catheter was placed in the superselective location very close to the tumor.
Gelfoam sponge was then injected to temporarily occlude the arterial blood flow.
|
ACTIVE_COMPARATOR: RFA
Recent advances in local ablation are aimed to expand the ablation size (> 3cm in diameter) in a minimal session by utilizing the switching RF controller and simultaneous 2 or 3 RF electrodes placement.
The procedure of RFA was according to manufacture algorithm.
RFA was performed within 7 days after TACE because the embolization effect in reducing blood flow will be not evident afterwards.
