Intense Prostate-specific Membrane Antigen Avid Hepatic Metastatic Lesions Shortly After Finishing 6 Cycle Pluvicto Treatment

A 71-year-old man was diagnosed with prostate cancer in 2012. After treatment with hormone, chemo, and combinations subsequently, the baseline prostate-specific membrane antigen PET scan revealed 130+ nodal and osseous metastatic lesions. After 4 doses of pluvicto, a partial response was appreciated. However, new intense prostate-specific membrane antigen avid hepatic lesions occupied around 30% of the liver with poorly differentiated metastatic prostate cancer 55 days after the last dose of pluvicto and markedly elevated prostate-specific antigen. This case highlights the need for vigilant monitoring and alternative treatment strategies.
