Pilot Study on Focal Prostate Radio-Frequency Ablation

Status Completed

Clinical Trial Summary

This is a prospective pilot study. The purpose of this research study is to evaluate the safety and efficacy of focal Radio-Frequency Ablation (RFA) in men with low-risk, clinically localized prostate cancer.

Clinical Trial Description

RFA is a minimally invasive procedure. It is an image-guided technique that heats and destroys cancer cells. In RFA, imaging techniques such as ultrasound or magnetic resonance imaging (MRI) are used to help guide a needle electrode into a cancerous tumor. High-frequency electrical currents are then passed through the electrode, destroying the cancer cells. Use of an RFA device was approved by the Food and Drug Association (FDA) in 1997 for the purposes of treating soft tissue tumors. The device we (Moffitt Cancer Center) will be using in this study has clearance for clinical use from the FDA. The effectiveness of the device is measured using biopsy cores at the site of the cancer after the RFA procedure. To evaluate the benefits of this procedure, we will also evaluate the change in quality-of-life indicators from baseline to 6 months following RFA. RFA is being developed as a minimally invasive potential treatment for prostate cancer.

This research study is a pilot clinical trial. Pilot clinical trials are smaller versions of larger studies that are conducted to prepare for the larger study. This pilot study pre-tests a research device before a large-scale multicenter study is launched.

The specific purpose of this pilot trial is to find out if RFA can effectively treat prostate cancer with fewer side effects including effects on urination, bowel function, and sexual function. RFA for early stage prostate cancer is designed to affect only the part of the prostate where cancer has been detected. The reasoning for this approach is the smaller the area given RFA, the less damage to surrounding tissues. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
