Feasibility Study for Organ Confined Prostate Cancer Treatment With HIFU Using SONABLATE System
- Determine the ability of Sonablate to focus ultrasonic waves for the purpose of
selectively destroying prostate cancer tissue, with resultant drop in PSA levels to
below 0.5 ng/mL and negative biopsy for cancer cells, in patients with organ-confined
OUTLINE: This is a multicenter study.
A probe is inserted into the rectum. High-intensity focused ultrasound (HIFU) energy using
the Sonablate system is delivered to the prostate tissue over approximately 2-3 hours.
Patients with residual cancer lesion (by biopsy), PSA greater than 0.5 ng/mL or increasing
PSA levels taken at least 2 months apart, visible prostate tissue on ultrasound, and no
local or distant metastases after day 90 undergo retreatment with HIFU.
Patients are followed at 2, 14, 30, 90, and 180 days.
PROJECTED ACCRUAL: A total of 20 patients will be accrued for this study.
