Brief Summary:

This is a prospective data collection of men who are electing to undergo prostate hemi-gland cryoablation.

The purpose of this observational research study is to investigate the localized treatment of prostate cancer using hemi-gland cryoablation.

UCLA patients undergoing hemi-gland cryoablation are a unique cohort compared to prior research because all patients at UCLA have had a pre-treatment multi-parametric MRI and Ultrasound fusion targeted biopsy; they will be followed in a similar fashion. This results in more precise assessment of a target region of cancer for ablation which may, in turn, result in improved clinical outcomes.

Intervention Details:
  • Device: Hemigland Cryoablation
    Hemigland cryoablation for the treatment of prostate cancer
    Other Name: cryotherapy

Primary Outcome Measures :
  1. Clinical Response to Cancer Treatment [ Time Frame: 6 months ]
    Our primary endpoint will be a patient's clinical response to cancer treatment, specifically, the degree of prostate cancer on a post-treatment fusion biopsy compared to pre-treatment.

Secondary Outcome Measures :
  1. Quality of Life Assessment - Urinary Function [ Time Frame: 6 months ]
    Comparison of urinary function pre- and post-treatment will be obtained using the International Prostate Symptom Score (IPSS) and the Expanded Prostate Cancer Index Composite (EPIC-26) questionnaires to report combined overall urinary function assessments.

Other Outcome Measures:
  1. Quality of Life Assessment - Erectile Function [ Time Frame: 6 months ]
    Comparison of erectile function pre- and post-treatment will be obtained using the 5-Item International Index of Erectile Function (IIEF-5) Sexual Health Inventory for Men and the Expanded Prostate Cancer Index Composite (EPIC-26) questionnaires to report combined overall erectile function assessments.

Study Population
Patients who are candidates for hemi-gland cryoablation, and elect this treatment option as a standard of care procedure, will be considered for our clinical study and analysis of their outcomes. Subjects will provide informed consent to participate in this study during standard of care clinical visits at the Clark Urology Center at UCLA. Subjects will provide informed consent to allow study staff to abstract data from their medical records.

Inclusion Criteria:

  • Low or intermediate risk prostate cancer (Gleason ≤ 7) or select high-risk patients (Gleason 8 prostate cancer).
  • Prostate volume of ≤ 70 cc
  • Ability to complete informed consent form

Exclusion criteria:

  • Medical contraindication to follow-up multi-parametric magnetic resonance imaging (mpMRI) or prostate biopsy
  • Patients unable to tolerate general or regional anesthesia.
