A 66-year-old man was diagnosed with metastatic prostate cancer to the bones. The patient started 223Ra-dichloride (Xofigo) therapy in April 2019. 99mTc-MDP bone scan and 18F-fluciclovine (Axumin) PET/CT showed discordant but overall complementary findings that indicated disease progression after 5 doses of Xofigo therapy. The patient's prostate-specific antigen increased from 33.81 ng/mL at baseline before Xofigo therapy and up to 394.3 ng/mL after the fifth dose of Xofigo treatment. Because of disease progression, Xofigo therapy was discontinued.
