[177Lu]lu-Psma-617 Therapy in a Patient with Chronic Kidney Disease.
The Journal of nuclear medicine(2023)
Abstract
We report the dosimetric evaluation of prostate-specific membrane antigen-based radioligand therapy (RLT) for metastatic prostate can-cer in a patient with autosomal-dominant polycystic kidney disease. Methods: The patient received hemodialysis during each of 6 RLT cycles while staying as an inpatient. We used voxel dosimetry , blood sampling for the dose calculation.Results: The patient responded well to the RLT, as indicated by the prostate-specific antigen level decreasing from 298 to 7.1 ng/mL. The doses per cycle ranged from 0.19 to 0.4 Gy/GBq for the parotid gland, 0.14 to 0.28 Gy/GBq for the submandibular gland, 0.03 to 0.11 Gy/GBq per kidney , 0.10 to 0.15 Gy/GBq for the red bone marrow. Conclusion: This case suggests that [177Lu]Lu-PSMA-based RLT can be applied successfully and safely to a patient with chronic kidney disease undergoing hemodialysis.
