Multipolar Radiofrequency Ablation for Hepatocellular Carcinoma Using Extra Nodular Versus Intranodular Technique (ARMCENVIN)

This study is ongoing, but not recruiting participants.

The primary purpose of the trial is to demonstrate that at least a 40% drop of recurrence rate can be achieve in hepatocellular carcinoma patients treated with no touch multipolar radiofrequency ablation technique compared to those treated with usual intranodular multipolar technique.

Condition Intervention
Hepatocellular Carcinomas
Procedure: Radiofrequency ablation

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Multipolar Radiofrequency Ablation for the Treatment of Hepatocellular Carcinoma Using Classical Intranodular Technique Versus Extra Nodular Technique So-called "No Touch" Technique: A Prospective Randomized Trial

Further study details as provided by Assistance Publique - Hôpitaux de Paris:

Primary Outcome Measures:
  • 2 years global (local+distant) recurrence rate [ Time Frame: 2 years ]

Secondary Outcome Measures:
  • 2 years local recurrence rate [ Time Frame: 2 years ]
  • 2 years distant recurrence rate [ Time Frame: 2 years ]
  • Primary treatment effectiveness (assessed 1 month after completion of treatment course which can include up to 3 radiofrequency ablation (RFA) procedures performed monthly) [ Time Frame: 2 years ]

Enrollment: 216
Study Start Date: February 2010
Estimated Study Completion Date: March 2017
Estimated Primary Completion Date: March 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: extranodular "no touch" multipolar RFA Procedure: Radiofrequency ablation
Percutaneous multipolar radiofrequency ablation.
Other Name: radiofrequency extranodular or intanodular ablation
Active Comparator: intranodular multipolar RFA Procedure: Radiofrequency ablation
Percutaneous multipolar radiofrequency ablation.
Other Name: radiofrequency extranodular or intanodular ablation

Detailed Description:

206 patients with hepatocellular carcinoma(s) including up to three nodules measuring up to four cm in diameter, will be randomized in two therapeutic legs: multipolar no touch radiofrequency versus multipolar intra nodular radiofrequency. Patients previously treated for hepatocellular carcinoma will not be enrolled in the study. Diagnostic of hepatocellular carcinoma will be based on American Society of Liver Diseases guide line. Early response to the treatment will be assessed one month after the radiofrequency ablation procedures (up to three in case of incomplete necrosis) with dynamic contrast medium enhanced CT or MRI liver examinations. For the follow up dynamic contrast medium enhanced CT or MRI liver examinations will be performed every three months.

The trial will last for 73 months including 45 months for the recruitment of patients. The main criteria of judgement will be the 2-years recurrence rate.
