Focal MR-Guided Focused Ultrasound Treatment of Localized Low-Intermediate Risk Prostate Cancer: Feasibility Study

Official Title

Focal MR-Guided Focused Ultrasound Treatment of Localized Low-Intermediate Risk Prostate Cancer: Feasibility Study

Summary:

The hypothesis of this feasibility study is that focal treatment with ExAblate MRgFUS has the potential to be a safe and effective non-invasive treatment for low to intermediate risk, organ-confined prostate cancer involving low incidence of morbidity. The study hypothesis will be tested by measuring treatment-related safety and initial effectiveness parameters in the ExAblate MRgFUS treated patients, as described above. Based on the result of this study, InSightec will initiate a larger study in an effort to approve low risk, organ-confined prostate cancer as an indication for its ExAblate MRgFUS device.

Trial Description

Primary Outcome:

  • Safety and initial Effectiveness
Secondary Outcome:
  • Safety
  • Effectiveness
  • Effectiveness
  • QOL
Objective of this feasibility trial is to assess safety and initial effectiveness of ExAblate MRgFUS in the treatment of low to intermediate risk, localized (organ confined) prostate cancer tumours. ExAblate treatment will be implemented as a focal tumour-selective therapy, directed at pre-defined volume(s)/sector(s) in the prostate, (identified as cancerous by mapping biopsy with or without multi-parametric MRI), rather than a whole gland or hemi-ablation treatment. Safety: evaluate incidence and severity of adverse events associated with ExAblate's MRgFUS focal treatment of low risk organ confined prostate cancer. The risk of ExAblate treatment-related incontinence and impotence will also be assessed in this study. Effectiveness: determine the tumour control effect of ExAblate's MRgFUS focal treatment of low risk organ-confined prostate cancer (confirmed by TRUS-guided Transperineal Mapping Biopsy results).
