About this study

Radium-223 is an established radionuclide therapy for patients with metastatic castration resistant prostate cancer (mCRPC) and symptomatic bone metastasis. Patients are eligible for this treatment when they have mCRPC and bone metastases; limited extraskeletal lesions (local prostate, lymph nodes \<3 cm) on conventional contrast enhanced CT (ceCT) were allowed in the registration trial(1). Previous research revealed that extraskeletal disease on ceCT and bone scans correlates with a poor response. Meanwhile, 68Ga-PSMA-PET/CT emerged as more sensitive imaging strategy that increases the detection of extraskeletal prostate cancer metastases. It is unclear whether these extraskeletal lesions harbour any predictive value in the treatment of mCRPC patients with Radium-223.
