Prostate-specific membrane antigen (PSMA) is highly expressed on prostate epithelial cells and strongly up-regulated in prostate cancer (PC), making it an optimal target for the treatment of metastasized PC. Radioligand therapy (RLT) with 177Lu-PSMA-DKFZ-617 (Lu-PSMA) is a targeted therapy for metastatic PC. In this study, we retrospectively analyzed the(More)
A 75-year-old man with castrate-resistant prostate cancer and increasing prostate-specific antigen (PSA) level developed severe bone marrow depression during Ra radionuclide therapy. Because of this, he was treated with Lu-PSMA in compassionate use for this not-yet-approved therapy. At the beginning of Lu-PSMA therapy, repeated blood transfusions (BT) were(More)
An 81-year-old castrate-resistant prostate cancer man with multiple lymph node, bone, and hepatic metastases received four cycles of Lu-PSMA-617 treatments at our department from May to December 2015. All of his liver metastases showed PSMA expression in Ga-PSMA PET performed before the first cycle. Under this therapy, all of the metastases showed(More)
A 64-year-old man with prostate cancer and an increasing prostate-specific antigen (PSA) level under therapy with abiraterone acetate underwent a therapy with Ra. Before the first therapy and 4 weeks after the last cycle, the patient underwent Ga-PSMA PET, which showed a clear response of bone metastases.
An 80-year-old patient with castrate-resistant prostate cancer presented to our department for PSMA imaging because of a rising prostate-specific antigen (PSA) level. The tumor was diagnosed in 2004. GnRh analog was the only treatment the patient received. Two cycles of Lu-PSMA-617 were performed with a 2-month interval in between. Ten months after(More)
Prostate cancer was diagnosed in a 71-year-old man with an elevated prostate-specific antigen. The CT of the abdomen showed multiple para-aortal lymph nodes, and thus, a Ga anti-prostate-specific membrane antigen (PSMA-11) PET/CT was initiated, which showed, aside from the prostate cancer and multiple iliacal and para-aortal lymph node metastases, an(More)
Ipilimumab (YERVOY) is a monoclonal CTLA-4-antibody with anti-tumor-immunogenic effect and is used to treat malignant melanoma. In this case study, we present [18F]Fluorodeoxyglucose Positron Emission Tomography (FDG-PET) images of a 37-year-old woman with metastatic melanoma, who was previously treated with interferon-alpha therapy and dacarbazine and(More)
Up to 30% of patients with castration-resistant prostate cancer (CRPC) do not show any response to the first cycle of radioligand therapy (RLT) with [177Lu]Lu-PSMA-617 (Lu-PSMA). We evaluated patient response to the second and third cycles of RLT in patients that underwent at least three cycles. The second aim of this study was to calculate the median(More)
A rare accident of a subcutaneous extravasation in the elbow with 4280 MBq Lu-PSMA-617 occurred in our clinic. We tried to reduce the damage by warming the elbow for 12 hours, then cooling it, and recommended the patient avoid exercises with the elbow for the next 3 days. We recognized a good resorption of the radionuclide in the scintigraphic imaging in(More)
