High-Intensity Focused Ultrasound Focal Ablation in Treating Patients With Progressive Prostate Cancer

August 23, 2013 updated by: University College London Hospitals

HIFU Lesion Control in Patients With Non-metastatic Progressive Prostate Cancer

RATIONALE: High-intensity focused ultrasound focal ablation uses high-energy sound waves to kill tumor cells.

PURPOSE: This phase II trial is studying the side effects of high-intensity focused ultrasound focal ablation and to see how well it works in treating patients with progressive prostate cancer.

Study Overview

Detailed Description

OBJECTIVES:

Primary

  • To evaluate the side effects of high-intensity focused ultrasound (HIFU) ablation in men with non-metastatic progressive prostate cancer.
  • To evaluate the quality of life of patients treated with this regimen.

Secondary

  • To determine the success of index lesion ablation with HIFU at 6 months after treatment by demonstrating the absence of cancer in the treated or ablated area by transrectal ultrasound biopsy.
  • To evaluate the prostate-specific antigen kinetics after index lesion ablation in patients treated with this regimen.
  • To evaluate the proportion of men who require androgen blockade at 12 months of follow-up.

OUTLINE: Patients undergo focal ablation with high-intensity focused ultrasound (HIFU) ablation on day 1. Treatment may repeat at 6 months in patients with progressive disease.

Blood samples and prostate biopsies are collected periodically for further analysis.

Patients complete questionnaires (IPSS, IPSS-QoL, ICS, IIEF-5, and FACT-P) at baseline and periodically during study.

Description

DISEASE CHARACTERISTICS:

  • Histologically confirmed prostate cancer by transrectal or transperineal template prostate biopsies

    • Stage ≤ T3bN0M0
    • Gleason grade ≤ 8
    • Serum PSA ≤ 20 ng/mL
    • Bone scan- or cross-sectional imaging-negative for metastatic or nodal (outside prostate) disease
    • No metastatic disease and/or nodal spread by CT scan or MRI
  • Index lesion or other secondary lesions with a volume ≥ 0.5 cc by MRI
  • No prostatic calcification and cysts (on transrectal ultrasound) that would interfere with effective delivery of therapy

PATIENT CHARACTERISTICS:

  • Able to tolerate a transrectal ultrasound
  • Not allergic to latex
  • Fit for major surgery as assessed by a consultant anaesthetist
  • Able to have MRI scanning (i.e., none of the following conditions: severe claustrophobia, permanent cardiac pacemaker, metallic implant, etc.)

PRIOR CONCURRENT THERAPY:

  • No prior radiotherapy
  • No androgen suppression and/or hormone treatment within the past 12 months
  • No prior significant rectal surgery preventing insertion of transrectal high-intensity focused ultrasound (HIFU) probe (decided on the type of surgery in individual cases)
  • No prior transurethral resection of the prostate (or equivalent procedures) within the past 2 years
  • No prior HIFU, cryosurgery, thermal, or microwave therapy to the prostate
