Recently radiolabeled ligands targeting prostate specific membrane antigen (PSMA) have been introduced for diagnostics and treatment of prostate cancer. Labeled with Lutetium, PSMA radioligand therapy (RLT) is one of the most promising new treatments of metastatic castration refractory prostate cancer. We present images of Ga-PSMA PET/CT and parameters of response of a 75-year-old heavily pretreated metastatic castration refractory prostate cancer patient with extended bone metastases, showing an extraordinary biochemical response in PSA-levels concordant to SUV decline in bone metastases. Furthermore, this case shows that CT is of no use in assessing response in bone metastases of prostate cancer.
