Low Dose Hemi-body Radiation For Recurrent Prostate Cancer

Not Applicable
Completed
Conditions
Prostate Cancer
Interventions
Radiation: Low Dose Radiotherapy
Registration Number
NCT03196778
Lead Sponsor
Juravinski Cancer Center
Brief Summary

Older studies in animals and humans have shown cancer responses to very low doses of whole-body or hemi-body radiation. To study the effects of low doses of radiation in patients with recurrent prostate cancer, investigators will enroll up to 21 patients for 10 fractions of low dose radiation, delivered over 5 weeks. Participants will be followed on study for 12 months, capturing PSA, CBC, QoL and blood samples for immunological analysis.

Exclusion Criteria
  • Prior treatment with chemotherapy and/or abiraterone and/or enzalutamide and/or radium-223.
  • Receiving treatment with immunosuppressive medications.
  • Platelet count below 50,000/µl (50 x 109/l) or leukocyte count below 3,000/µl (3 x 109/l) or granulocyte count below 2,000/µl (2 x 109/l).
  • Other medical conditions or co-morbidities which, in the opinion of the Investigator, may interfere with the participant's ability to participate in the study.
  • Language difficulties which may hinder the patient's ability to complete the trial.
