  Purpose

RATIONALE: Ultrasound therapy kills tumor cells by heating them to several degrees above body temperature. This treatment may be effective for prostate cancer.

PURPOSE: Phase III trial to determine the effectiveness of ultrasound therapy in treating patients who have stage I or stage II prostate cancer that has recurred following radiation therapy.


Condition Intervention Phase
Prostate Cancer
Procedure: high-intensity focused ultrasound ablation
Phase 3

Study Start Date: July 1999
Detailed Description:

OBJECTIVES: I. Determine the effectiveness of the Ablatherm high-intensity focused ultrasound device in providing control of disease for at least 12 months after treatment in patients with stage I or II prostate cancer recurring after external beam radiotherapy. II. Determine the safety of this treatment device in these patients.

OUTLINE: This is an open-label, multicenter study. A probe is inserted into the rectum. Ultrasound energy is then delivered through probe to prostate tissue over 2-3 hours. Quality of life is assessed at study initiation; at 14 days and 3, 6, and 12 months; and then annually thereafter. Patients are followed at 14 days; at 3, 6, 9, and 12 months; and then annually thereafter.

PROJECTED ACCRUAL: A total of 120 patients will be accrued for this study.

Criteria

DISEASE CHARACTERISTICS: Histologically proven stage I or II prostate cancer Organ confined (T1 or T2) At least 1 current positive biopsy Failed prior external beam radiotherapy for T1-T2 prostate cancer within last 18 months (with no worsening of the cancer in the first 12 months after radiotherapy) PSA nadir less than 4 ng/mL after external beam radiotherapy If prior hormonal therapy, PSA must be greater than 1.0 ng/mL and testosterone level normal after therapy Prostate volume no greater than 35 g, or 35-50 g if maximum anterior posterior diameter no greater than 2.5 cm Kattan Nomogram at least .50 60-month recurrence-free probability prior to external beam radiotherapy ASA Classification 1-3 No lymph node involvement by CT scan No metastases No prostate seroma, prostate abscess, or active prostatitis Must meet the following conditions: No artificial sphincter, penile prosthesis, or intraprostatic implant such as stent or catheter Normal rectal anatomy and rectal mucosa Rectal wall measurement no greater than 6 mm with treatment probe in place No calcification inducing a shadow in the prostate that would preclude study No significant rectal or bladder morbidity after radiotherapy (RTOG/EORTC rectal or bladder scores at least 2) No rectal fibrosis, stenosis, fistula, disease, or other rectal anomalies that would make rectal probe insertion difficult
