Complete Regression of Lung Metastases in a Patient With Metastatic Castration-Resistant Prostate Cancer Using Lu-177-PSMA Radioligand Therapy

摘要

Patients with metastatic castration-resistant prostate cancer (mCRPC) and visceral (liver or lung) metastases have a poor prognosis and worse outcomes than those with bone disease with or without lymph nodes involvement. The high prostate-specific membrane antigen expression in prostate cancer metastases makes it a promising approach for targeted radionuclide therapy of prostate cancer. Lutetium-177 (Lu-177)-labeled prostate-specific membrane antigen radioligand therapy (Lu-177-PRLT) has demonstrated encouraging efficacy inmCRPC. We report here anmCRPC patient with lung, lymph nodes, and extensive bone metastases, who underwent Lu-177-PRLT and had excellent response to the treatment and complete regression of lung metastases after Lu-177-PRLT.
