Upfront Use of 177Lu-Labeled PSMA Radioligand Therapy and Treatment Response Assessment in Treatment-Naive Prostate Cancer.

Abstract

Prostatic malignancy is the most common type of nonskin cancer and associated with significant morbidity and mortality. Early androgen deprivation therapy (ADT) is the treatment of choice in metastatic prostate cancer, whereas ADT delays progression of disease, but it is associated with significant adverse effects and frequently impairs the quality of life. Therefore, there is growing interest in treatments to postpone ADT while achieving a good progression-free survival. We present a case of oligometastatic prostate cancer, who was treated upfront with 177Lu-labeled PSMA radioligand therapy and demonstrated excellent response to a single dose of 177Lu-PSMA-617.
