Exploring Theranostic Avenues in Adrenocortical Carcinoma Using Chemokine Receptor and Prostate-Specific Membrane Antigen-Directed PET/CT

Abstract

We report on an adrenocortical carcinoma (ACC) patient, which has exhausted previous treatment options and was scheduled for prostate-specific membrane antigen (PSMA)- and C-X-C motif chemokine receptor 4 (CXCR4)-targeted PET/CT. We identified PSMA-avid pulmonary metastases exhibiting modest radiotracer accumulation, while chemokine receptor PET/CT provided intense uptake. This dual-tracer molecular imaging approach revealed that chemokine receptor PET appears to be more suitable in patients with advanced ACC, indicating that CXCR4-directed radioligand therapy may be considered in such patients suffering from end-stage disease. Given its dismal prognosis, chemokine receptor-directed theranostics may therefore extend the therapeutic armamentarium as last-line option in advanced ACC.
