  Purpose

This is a clinical research study designed to determine the safety and efficacy of the application of a unique interstitial radio frequency thermal therapy for the treatment of large tumours in the kidney or liver. The novel device offers patients a more effective therapy than conventional RFA and for patients with large tumours fewer number of treatments and needle insertion sites. The clinical treatment volumes (or sites of focal tumours) will be determined by a combination of biopsy and contrast enhanced CT imaging.

The study will assess if novel device can produce lesions in the liver or kidney in a controlled and predictable manner and with sufficient size to effectively manage disease progression in the organ. The extent of lesion size at a delivered power setting and treatment time will be measured with post-treatment CT or MRI and biopsy as measures of tissue response

Primary Outcome Measures:
  • RF electrodes can be accurately and safely placed in the desired location [ Time Frame: up to 10 days prior to surgery and up to 24 hrs after surgery ] [ Designated as safety issue: Yes ]
    this will be assessed during the surgery and once the tumour is removed and examined


Secondary Outcome Measures:
  • The safety of energy application with the RF coil device including assessing effect on surrounding liver tissue [ Time Frame: up to 10 days prior to surgery and up to 24 hrs after surgery ] [ Designated as safety issue: Yes ]
    This will be assessed during the surgery and once the tumour is removed and examined

  • Verifying that large (>2cm) liver tumors are effectively ablated with RF energy [ Time Frame: up to 24hrs after surgery ] [ Designated as safety issue: Yes ]
    Once the tumour is removed, the ablation field can be fully examined.


Estimated Enrollment: 12
Study Start Date: August 2011
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: August 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Acute
the RFA thermal coil will take place at the time of surgery, just prior to tumour removal
Device: RFA Loosely wound thermal coil

This new device uses radiofrequency energy to destroy kidney or liver tumours. It is called radiofrequency ablation.

This type of energy is simply an alternating current that passes from a coil (electrode) into the tissue causing heating of the tissue in the vicinity of the electrode.

Other Name: This device has been developed by the University Health Network
Experimental: Delayed
The RFA thermal coil procedure will occure 6-10 days prior to the surgery for tumour removal
