Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study collects imaging data in the form of multiparametric magnetic resonance imaging (mpMRI) prior to initiation of therapy(s) and at three time points post radiotherapy, as well as Prostate Specific Membrane Antigen (PSMA) Positron Emission Tomography (PET) prior to the initiation of radiotherapy and at 18-months post radiotherapy. Prostate specific antigen (PSA) blood tests represent the standard measure of treatment response and will be collected at time points in addition to non-standard blood tests corresponding to collection of imaging data in participants undergoing standard radiotherapy for prostate cancer treatment.
The interventions involved in this study are as follows;
PSMA PET at baseline (may be standard at the site) and again at 18 months post radiotherapy treatment (not standard). The PSMA PET scan involves the use of an intravenously administered radioactive drug (tracer) followed by the scan. The PSMA PET scan will be performed by a suitably qualified allied health professional.
mpMRI - three additional MRI scans with contrast above what is normal standard of care. The MRI scans will involve the use of a contrast agent administered intravenously by the treating doctor. The standard of care MRI used for radiotherapy planning will utilise contrast which may not be standard of care in some centres. The MRI scan will be performed by a suitably qualified allied health professional. mpMRI scans will be performed at time of radiotherapy planning, and then 6, 12 and 18 months post radiotherapy treatment.
Full Blood Count (FBC) and Electrolytes, Urea and Creatinine (EUC) at four timepoints (prior to radiotherapy planning, and then 6, 12 and 18 months post radiotherapy treatment) which are not standard blood tests for this group of patients. Measurement of Testosterone is also not standard in patents not on androgen deprivation therapy (ADT).

Patients who are being treated using ADT as part of their standard treatment for their prostate cancer compared to those that who are not being treated using ADT will complete one additional mpMRI and one additional blood test prior to the commencement of ADT in addition to the interventions outlined above.
