Outcomes of Local Treatment for Oligometastatic Prostate Cancer Diagnosed Using PSMA PET Imaging: OLIGOMET Study

PSMA-PET/CT or PSMA-PET/MRI are more accurate imaging modalities compared to CT/BS; in approximately 10-20% of high-risk patients diagnosed using conventional imaging PSMA-PET up-stages the disease. Therefore a substantial proportion of high-risk patients previously considered as non-metastatic are expected to be diagnosed with oligometastatic disease. While standard treatment pathways exist for patients with non-metastatic or oligometastatic disease confirmed using conventional imaging, less is known about the optimal management of patients with oligometastatic prostate cancer on PSMA-PET. Currently, data on the safety, effectiveness and oncologic outcomes of local therapies in oligometastatic patients diagnosed using PSMA-PET have been poorly reported so far. Thus, there is a need for a prospectively maintained database to collect real-world clinical data to produce high-quality research on the optimal management in oligometastatic prostate cancer who underwent PSMA-PET for primary staging and subsequent local therapy. This database will allow centers to retro- and prospectively collect data to facilitate analysis and assessment of the outcomes of oligometastatic patients managed with local therapy.
