Triple-tracer Molecular Imaging Using 18F-FDG, 68Ga-PSMA and 68Ga-OCTREOTATE to Characterize Metastatic Castration-resistant Prostate Cancer (mCRPC) and Evaluate Eligibility for Radionuclide Therapies
Prostate cancer (PCa) is the most common solid organ cancer in North American men. Patients becoming refractory to loco-regional therapy receive androgen deprivation therapy, but their disease will inevitably progress to metastatic castration-resistant prostate cancer (mCRPC). Treatment failure and poor progression-free survival could be explained by the fact that PCa metastases in the same patient may be polyclonal, showing opposite responses to systemic therapies. This project aims to recruit 100 patients with mCRPC in order to determine the prevalence of intrapatient intermetastasis polyclonality and NED using PET/CT triple-tracer PSMA/FDG/OCTREOTATE imaging and eligibility for either PSMA or OCTREOTATE radioligand therapy (RLT).
