Eligibility Criteria

Age40 Years+
Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Histologically proven prostate cancer
  • A visible lesion on multiparametric Magnetic Resonance Imaging (mpMRI), that is accessible to a treatment based on radiofrequency bipolar electrodes
  • Transperineal prostate biopsies (template mapping and/or targeted) correlating with clinically significant lesion in the area of the Magnetic Resonance (MR)-visible lesion
  • Absence of clinically significant histological disease outside of the planned treatment zone
  • Radiological stage T1-T3aN0M0 disease, as determined by local guidelines
  • Serum prostate-specific antigen (serum PSA) \</=15ng/ml within 3 months of screening visit
  • Life expectancy of more than 10 years
  • Signed informed consent by patient
  • An understanding of the English language sufficient to understand written and verbal information about the trial and consent process

You may not qualify if:

  • Men who have had previous radiation therapy to the pelvis
  • Men who have had androgen suppression/hormone treatment within the previous 12 months for their prostate cancer
  • Men with evidence of metastatic disease or nodal disease outside the prostate on bone scan or cross-sectional imaging
  • Men with a tumour not visible on mpMRI
  • Men with an inability to tolerate a transrectal ultrasound (TRUS)
  • Men allergic to latex
  • Men who have undergone prior significant rectal surgery preventing insertion of the transrectal ultrasound probe (decided on the type of surgery in individual cases)
  • Men who have had previous electroporation, radiofrequency ablation, High Intensity Focused Ultrasound (HIFU), cryosurgery, thermal or microwave therapy to the prostate
  • Men who have undergone a Transurethral Resection of the Prostate (TURP) for symptomatic lower urinary tract symptoms within the prior 6 months. These patients may be included within the trial if deferred from consent and screening until at least 6 months following the TURP
  • Men not fit for major surgery as assessed by a Consultant Anaesthetist
  • Men unable to have pelvic MRI scanning (severe claustrophobia, permanent cardiac pacemaker, metallic implant etc likely to contribute significant artefact to images)
  • Presence of metal implants/stents in the urethra
  • Men with renal impairment with a Glomerular Filtration Rate (GFR) of \<35ml/min (unable to tolerate Gadolinium dynamic contrast enhanced MRI)
