NCT02290561

Brief Summary

The purpose of this study is to assess how accurately SmartTarget can direct high intensity focused ultrasound (HIFU) to a pre-defined area (cancer) in the prostate. The current standard methods for treating prostate cancer are directed to the whole gland - either surgery to remove it or radiotherapy. An alternative method is focal therapy. This is surgery that uses an energy source to ablate the cancer whilst preserving the normal healthy tissue. Prior to surgery prostate cancer can often be localised using MRI imaging and detailed prostate biopsy techniques. The difficulty is that during surgery it is very difficult to accurately locate the cancer on the live ultrasound images - to compensate surgeons will treat half or a quarter of the prostate to ensure that the cancer is treated. This may cause higher rates of side-effects. SmartTarget is an MRI to ultrasound fusion device that maps the pre-treatment MRI onto the live ultrasound during surgery. It then provides a target for the surgeons to treat during the operation. The results will measure if the area intended to treat was covered and if how accurate the treatment was by comparing the pre-treatment MRI with a 1 week post treatment scan

Outcome Measures

Primary Outcomes (1)

  • Target Ablation

    The ability of SmartTarget-directed focal HIFU therapy to ablate an intended target within the prostate, as measured by the proportion of men in whom complete ablation of the target region is achieved. Complete or incomplete ablation is determined by a comparative assessment of the pre-therapy and one week post-therapy contrast-enhanced MRIs by an expert radiologist.

    1 week post treatment

Secondary Outcomes (3)

  • Accuracy

    1 week post treatment

  • Length of the procedure

    intraoperative

  • Quality of Life

    6 weeks and 3 months

Interventions

  • Signed informed consent

You may not qualify if:

  • No lesion on mpMRI

  • Previous HIFU, cryosurgery, thermal, irreversible electroporation, radiofrequency or microwave therapy to the prostate.
  • Men with evidence of metastatic disease or nodal disease outside the prostate on bone scan or cross-sectional imaging
  • Men not fit for major surgery as assessed by a consultant anaesthetist
  • Men who are unable to give informed consent
