Phase II Laser Focal Therapy of Prostate Cancer
Running, not enrolling
Conditions studied: Prostate Cancer
In brief
Target recruitment: 1000 subjects. The purpose of this research study is to continue to investigate the safety and effectiveness of using MR (magnetic resonance) guided laser focal therapy for prostate cancer and to evaluate oncologic control over 20 years. We hypothesize that laser focal therapy can be used to achieve oncologic control in carefully selected patients. MR uses large magnets to produce pictures of areas/organs inside the body. The laser uses light to heat a target area to try to destroy cancerous cells. The laser system that will be used is called the Visualase® Thermal Therapy System. This system has been used for the treatment of brain, bone (spine), thyroid, and liver cancers. However; this study is the first time this system has been studied for use in the treatment of prostate cancer with a trans-rectal approach. MR-guided biopsies and laser applicator placement will be performed using the Invivo DynaTRIM trans-rectal biopsy guidance system. This system is cleared (approved) by the U.S. Food and Drug Administration (FDA) for such uses.
