Detailed Description
Transcatheter arterial chemoembolization (TACE) has been playing an important role in the treatment algorithm for patients with multifocal or large intrahepatic lesions of hepatocellular carcinoma (HCC) not eligible for surgical resection, transplantation, or local ablative therapy. The use of balloon assisted TACE has been proposed recently and it could be one of the possible ways to improve the effectiveness of drug delivery to the target tumor and therefore leading to improved treatment outcome.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Other: Ballloon catheter Balloon-assisted transarterial therapy will be performed in the first treatment session only |
Procedure: The balloon catheter is placed at the various arterial feeders of the tumor
use of a balloon catheter for providing balloon occlusion, in addition to the standard microcatheter for drug delivery, both catheters are to be placed in parallel through a single guide catheter. Only one arterial puncture wound is involved. The inflated balloon provides temporary occlusion of all arterial tumor feeders except for the one which is selectively catheterized with a microcatheter for delivery of the therapeutic agent. The therapeutic agent consists of Lipiodol mixed with a chemotherapeutic drug, it is delivered through the microcatheter under fluoroscopic control.

Outcome Measures
Primary Outcome Measures
- The change in hemodynamics of arterial blood supply to HCC tumors [immediately after completion of procedure]
The change in number of feeding arteries
- The change in the perfusion pattern of HCC tumors [immediately after completion of procedure]
The change in perfusion pressure.
Secondary Outcome Measures
- The degree of completeness of coverage of the tumor vasculature [within 30 minutes after completion of procedure]
The degree of completeness of coverage of the tumor vasculature at the completion of the treatment as evaluated on CT scan
- Tumor response [3 months]
Tumor response by CT such as complete response according to European Association for the Study of the Liver (EASL) necrosis guidelines.
