NCT01226576

Brief Summary

The hypothesis of this feasibility study is that focal treatment with ExAblate MRgFUS has the potential to be a safe and effective non-invasive treatment for low to intermediate risk, organ-confined prostate cancer involving low incidence of morbidity. The study hypothesis will be tested by measuring treatment-related safety and initial effectiveness parameters in the ExAblate MRgFUS treated patients, as described above. Based on the result of this study, InSightec will initiate a larger study in an effort to approve low risk, organ-confined prostate cancer as an indication for its ExAblate MRgFUS device.

Eligibility Criteria

Age50 Years - 75 Years
Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patient of age between 50 to 75 years, inclusive.
  • Biopsy confirmed adenocarcinoma of the prostate, performed up to 6 months prior to scheduled treatment.
  • Patient with low-intermediate risk, early-stage organ-confined prostate cancer (cT1c and cT2a, N0, M0), diagnosed with TRUS guided transperineal biopsy (TPBx) and voluntarily chooses MRgFUS as the non-invasive treatment, who may currently be on watchful waiting or active surveillance and not in need of imminent radical therapy.
  • Patient with PSA less than or equal to 10 ng/mL
  • Gleason score 6 or 7 (no 5 grades), based on TRUS guided Transperineal Mapping Biopsy, as defined in the protocol.
  • Up to two (2) cancerous lesions may be identified in the prostate; each tumor is not more than 10 mm in maximal linear dimension; each tumor should comply with the maximal 7 Gleason score requirement.
  • Positive TRUS-guided transperineal biopsy (TPBx) cores, detected in a maximum of four (4) sectors, (2 for each cancerous focus) out of 16 sectors (or out of 12 sectors in prostates with volume \<20 cc)
  • Low grade tumors may or may not be visible by multi-parametric MRI. Thus, in case of MRI-visible tumor, tumor should be in capsular contact of less than 5 mm, on axial images.
  • No definite evidence of extracapsular extension or seminal invasion by MRI
  • Patient eligible for epidural anesthesia, and general anesthesia (in case of complication, requiring intervention).
  • Patient is willing and able to give consent and attend all study visits as defined in the protocol
  • Prostate gland volume should be no greater than 70 cc, volumetrically measured.

You may not qualify if:

  • ASA status \> 2
  • Contraindications to MRI 2.1. Claustrophobia 2.2. Implanted ferromagnetic materials or foreign objects 2.3. Known intolerance to the MRI contrast agent (e.g. Gadolinium or Magnevist) 2.4. Known contraindication to utilization of MRI contrast agent
  • Severely abnormal coagulation (INR\>1.5)
  • Patient with unstable cardiac status including:
  • Unstable angina pectoris on medication 4.2. Documented myocardial infarction within 40 days prior to enrolment 4.3. Congestive heart failure NYHA class IV 4.4. Unstable arrhythmia status, already on anti-arrhythmic drugs
  • Severe hypertension (diastolic BP \> 100 on medication)
  • Severe cerebrovascular disease (multiple CVA or CVA within 6 months)
  • History of orchiectomy, PCa-specific chemotherapy, cryotherapy, Photodynamic therapy or radical prostatectomy for treatment of prostate cancer; any prior radiation therapy to the pelvis for prostate cancer or any other malignancy.
  • Patient under medications that can affect PSA for the last 3 months prior to MRgFUS treatment (Androgen Deprivation Treatment; alpha reductase inhibitors)
  • Individuals who are not able or willing to tolerate the required prolonged stationary supine position during treatment (approximately 3 hrs.)
  • Any rectal pathology, anomaly or previous treatment, which can change acoustic properties of rectal wall or prevent safe probe insertion (e.g., fistula, stenosis, fibrosis).
  • Any spinal pathology which can prevent safe administration of epidural anesthesia
  • Identified calcification of 2 mm or more in largest diameter neighboring the rectal wall (in a distance of less than 5 mm) and interfering with the acoustic beam path.
  • Lower limb musculo-skeletal fixed deformities.
  • Prostate with multiple cystic lesions.
  • +13 more criteria
