Description of intervention(s) / exposure
This study aims to improve knowledge around the way that cancer spreads in men with advanced prostate cancer who receive targeted radiation therapy and androgen deprivation therapy (ADT).

This study does not direct treatment and any treatment decisions will be based on the recommendation of your treating doctor. This study is looking at the effects on bone lesions in individuals receiving this treatment. At study enrolment a 68Ga-PSMA PET CT scan will occur as part of standard of care treatment.

A 68Ga-PSMA PET CT is a nuclear medicine imaging test used in prostate cancer and it has higher diagnostic efficacy than conventional imaging. Radioactive tracers are injected and then taken up by tissues in your body. Activity within your organs are then detected by the PET scanner which shows how tissue and organs are working. This test takes approximately 2 hours with the scan itself taking up to half an hour. This nuclear medicine examination is considered safe with almost no reported adverse reactions attributable to the radiopharmaceuticals used.

This study requires two additional 68Ga-PSMA PET CT scans that are beyond standard of care. These scans occur at 6 and 12 months post enrolment. There are also optional blood tests that occur at enrolment, 6 and 12 months post enrolment. Blood tests are at the discretion of the individual participant.
