Purpose

The primary purpose of this study is to evaluate the feasibility and safety of MRI-guided focal laser ablation (Laser-Induced Interstitial Thermal Therapy, LITT) to treat low-risk native prostate cancer.

Detailed Description

      The study is being done to evaluate the safety and effectiveness of Magnetic Resonance
      Imaging (MRI)-guided focal laser therapy with the Visualase Thermal Therapy System to treat
      low-risk prostate cancer tumors. Unlike surgery or radiotherapy which affects a large portion
      of the prostate or the entire organ, localized or focal therapy is intended to treat a small
      portion of tissue in which the cancer has been found by biopsy.

          -  No definite radiographic indication of extra-capsular extension.

          -  Estimated survival of 5 years or greater, as determined by treating physician.

          -  Tolerance for anesthesia/sedation.

          -  Ability to give informed consent.

        Exclusion Criteria

          -  Presence of any condition (e.g., metal implant, shrapnel) not compatible with MRI.
