Eligibility Criteria

Inclusion

  • Subjects with untreated, organ-confined prostate cancer (clinical stage ≤ T2b, Gleason =7) x Age 40 to 85 years of age
  • Multi-parametric MRI at University of California at Los Angeles (UCLA) within 6 months of study treatment, demonstrating a Region of interest (ROI) of MRI (PIRADSv2 \> Grade 3). x Prostate volume 20cc to 80cc
  • Transrectal ultrasound-guided biopsy with ≥ 10 systematic biopsy cores and ≥ 2 targeted biopsy cores from above MRI-derived ROI within 6 month of biopsy results
  • Histologically-confirmed adenocarcinoma from targeted biopsy cores x Overall Gleason = 3+4 or 4+3
  • Subjects desire focal therapy and decline conventional treatment (active surveillance, radical prostatectomy, radiation therapy, cryosurgery and hormone therapy)
  • Signed informed consent for the FLA treatment through the 12 month follow-up

Exclusion

  • Any significant cancer outside of the intended treatment zone, defined as Gleason score 7 x \< 10 years life expectancy
  • Any medical condition that would compromise the subject's ability to safely ● Active bleeding disorder
  • Use of coumadin or any other anticoagulant, unless anticoagulation can be temporarily reversed or stopped for a window of at least 7 days peri-procedure
  • Active urinary tract infection x Active prostate abscess, prostatitis, or neurogenic bladder x Any prior treatment for prostate cancer, including:
  • Radical prostatectomy
  • Radiation therapy (external beam or brachytherapy)
  • Cryotherapy
  • High intensity focused ultrasound (HIFU) treatment o Photodynamic therapy o Androgen deprivation therapy
  • Prior prostate, bladder neck, or urethral stricture surgery
  • Any prostate debulking procedure, including: transurethral resection of prostate, photovaporization, or electrovaporization
  • Transurethral incision of bladder neck x Urethral stricture dilation or reconstruction
  • Use of 5-alpha reductase inhibitors within 6 months of treatment x Prior significant rectal surgery (hemorrhoidectomy is acceptable)
  • Rectal fissure, fibrosis, stenosis, or other anatomic abnormality precluding insertion of transrectal device
  • Inflammatory bowel disease x Urinary tract or rectal fistula x Previous urethral sling, artificial urinary sphincter or penile prosthesis surgery.
  • Any contraindication to MRI (contrast allergy, severe claustrophobia, MRI-incompatible prosthesis, MRI-unsafe aneurysm clips)
