Fusion Guided Focal Laser Ablation of Prostate Cancer

Background: Prostate cancer is the most common non-skin cancer in U.S. men. Treatments for early or less aggressive disease are limited. Researchers want to test a device that destroys cancerous tissue with laser energy. They want to see if using it with ultrasound is more comfortable than using it with magnetic resonance imaging (MRI). Objectives: To test a cooled laser applicator system to treat prostate cancer lesions. To see if ultrasound imaging is a practical and feasible treatment with laser ablation for focal prostate cancer treatment. Eligibility: Men at least 18 years old with prostate cancer seen on MRI that has not spread in the body. Design: Participants will be screened with standard cancer care tests. These can include physical exam, lab tests, and MRI. For the MRI, they lie in a machine that takes pictures. Participants will have a prostate biopsy. Needle samples will be taken from 12 places in the prostate. This will be guided by MRI and ultrasound, which is obtained through a coil in the rectum. Participants will stay at the clinic for 1 2 days. A cooling catheter (plastic tube) will be put in the bladder. Ultrasound will guide the laser applicator directly to the tumor. The cooling catheter will be removed. A different catheter will be put in the urethra to keep the bladder emptied. The next day, participants will have a physical exam and a PSA blood test. Participants will have 6 follow-up visits over 3 years. At each visit, they will have a physical exam and lab tests. At some visits, they will also have an MRI or other scans and a prostate biopsy.

Trial of ADT and SBRT Versus SBRT for Intermediate Prostate Cancer

Stereotactic body radiation therapy (SBRT) is a very precise form of radiation therapy that allows the physician to deliver more radiation dose in a single session. Because of this, the number of radiation sessions can be reduced from the typical 45-48 sessions, as in conventional daily session radiation, to 5 sessions given every other day over a week and a half. Giving the radiation at a higher dose during each treatment may be more effective in killing the prostate cancer cells than the standard way of using external radiation therapy where a small amount of radiation is given over many sessions. Androgen Deprivation Therapy (ADT) or hormonal therapy is one of the methods to treat intermediate risk prostate cancer. This therapy works by reducing the level of testosterone and stopping them from affecting your cancer. The ADT used in this study is known as Degarelix. Degarelix is an approved medication that reduces the body's production of testosterone; this medication is usually given to all men with intermediate risk prostate cancer getting external radiation. This study is a randomized study to find out whether combining stereotactic (also known as precision) radiation to the prostate cancer combined with a short course of Degarelix will result in a greater likelihood of killing the cancer in the prostate compared to stereotactic radiation therapy given alone. It has been shown that the combination of radiation with medications that interfere with testosterone production and its effects makes prostate cancer cells more sensitive to the radiation.
