Abstract
The role of prostate-specific membrane antigen (PSMA) targeted molecular imaging and radionuclide therapy in prostate cancer is well known. PSMA is also overexpressed in the neovasculature of a number of solid tumors, including renal cell carcinoma (RCC). Several studies have demonstrated the diagnostic utility of PSMA PET imaging in the setting of RCC. To date, no PSMA radioligand therapy of RCC patient has been reported according to literature. Here, we report our experience treating a patient with metastatic RCC with 177 Lu-PSMA I&T radioligand therapy, but unexpected imaging findings with rapid washout of 177 Lu-PSMA from the tumor.
