Excellent Response to Full-Dose 177 Lu-PSMA-617 RLT in Metastatic Castration-Resistant Prostate Cancer With Transplant Kidney : A Step Ahead.

177 Lu-PSMA radioligand therapy (RLT) has shown very encouraging results in metastatic castrate-resistant prostate cancer (mCRPC) patients with acceptable adverse events. The adverse events of RLT are mainly limited to salivary glands and kidneys. However, there is dearth of available data of RLT in transplanted kidney patients with mCRPC. Here is a case of 68-year-old mCRPC patient with history of renal transplant who underwent 4 cycles of 177 Lu-PSMA-617 RLT (~7.4 GBq/cycle). Posttherapy serum creatinine and glomerular filtration rate remained stable along with excellent response and symptomatic improvement, thus demonstrating the safety of full dose of 177 Lu-PSMA in renal transplant patients.
