About

This is a feasibility study to determine safety and the ability of HIFU (High Intensity Focused Ultrasound)to selectively destroy prostate cancer tissue in men who demonstrate local recurrence of prostate cancer following radiation treatment.

Full description

This is a feasibility study to determine the safety and the ability of HIFU (High Intensity Focused Ultrasound)to selectively destroy prostate cancer tissue in men who demonstrate local recurrence of prostate cancer following radiation treatment. All participants will receive treatment with HIFU and be monitored closely for recurrence of disease (if any),quality of life and adverse events.

Enrollment

Ages

40 to 80 years old

Inclusion criteria

· Male patients with an initial presentation of organ confined recurrent prostate cancer (clinical Stages T1 and T2 only) who have been treated with external beam radiation therapy or brachytherapy and subsequently has biopsy-proven local recurrence.
- Age > 40 years through <80 years.
- Anesthesia Surgical Assignment (ASA) categories I, II or III only.
- Negative radionuclide bone scan within 3 months prior to HIFU treatment to rule out the possibility of metastases.
- PSA levels >0.5ng/ml and <10ng/ml.
- Pre-radiation Gleason score < 8
- Clearly imageable prostate on TRUS
- Written informed consent.
