High Intensity Focused Ultrasound, or HIFU, is a therapy that destroys tissue with rapid heat elevation-which essentially destroys the tissue. Ultrasound energy, or sound waves, is focused at a specific location and at that “focal point,” the temperature raises to almost 90 degrees Celsius in a matter of seconds. Any tissue at the “focal point” is destroyed; however, any tissue outside of the focal point remains unharmed.

Patients who have been diagnosed with prostate cancer or who have been previously treated with radiation therapy and may potentially have recurrent prostate cancer may be candidates for this treatment.

Inclusion Criteria:

• Men with initial presentation of organ-confined recurrent prostate cancer (Clinical Stage T1c or T2a only), who have been treated with external beam radiation.

• PSA less than10 ng/mL, greater than0.5 ng/mL

• Negative bone scan

• Age 40 - 85 years old
