The 177Lu-labeled prostate-specific membrane antigen (LuPSMA) radionuclide therapy for metastatic castration-resistant prostate cancer is under investigation in a phase III trial (VISION: NCT03511664). However, patients with diffuse bone involvement, diagnosed with a "superscan" by bone scintigraphy at baseline, were excluded due to a lack of efficacy and safety data. We therefore aimed to investigate the feasibility of LuPSMA in patients with diffuse bone marrow involvement on baseline PSMA-targeted positron emission tomography. The primary end points were prostate-specific antigen (PSA) response (Prostate Cancer Working Group 3 [PCWG3]), hematologic safety profile (Common Terminology Crite..View full abstract
