Prostate Hypoxia FAZA

ClinicalTrials.gov Identifier:
NCT01567800
First received: March 23, 2012
Last updated: June 24, 2014
Last verified: June 2014
  Purpose

The purpose of this study is to look for low levels of oxygen (hypoxia) in prostate cancer using a special x-ray test called a positron emission tomography (PET)scan. Hypoxia may have an effect on how prostate cancer grows and responds to treatments like radiotherapy and chemotherapy. The use of PET scans to measure hypoxia may be better and simpler than the methods used previously.

Criteria

Inclusion Criteria:

  • Age => 18 years
  • Histologic diagnosis of adenocarcinoma of the prostate
  • Bulky intermediate risk, high risk or metastatic prostate cancer

Bulky intermediate risk: cT1-2 with >50% of diagnostic biopsy cores containing cancer and Gleason 6 or 7 and prostate specific antigen (PSA) >10 and ≤20 OR

High risk:

cT1-2 with Gleason score ≥8; or cT1-2 with PSA >20; or cT3 OR N+ and/or M1 disease OR Newly diagnosed hormone-refractory prostate cancer - Intention to treat using radiotherapy +/- concurrent and adjuvant hormonal therapy

  • Intention to treat with radiotherapy, hormonal therapy, other systemic treatment for prostate cancer, or a combination of these according to the Princess Margaret Genitourinary Site policies.
  • Previous or concurrent anti-cancer therapy for the PET FAZA target lesion allowed
  • Ability to provide written informed consent to participate in the study

Exclusion Criteria:

  • Inability to lie supine for more than 60 minutes
  • Patients taking the drug disulfiram (Antabuse)
  • Contraindications for MRI: only applicable in cases where the PET FAZA target lesion is identified as the prostate gland. Patients with target lesions at other anatomic sites will not undergo MR imaging.
  • Patients weighing > 136 kg
