Lutetium-177 prostate-specific membrane antigen (177Lu-PSMA) radioligand therapy is emerging as a promising treatment for metastatic castration-resistant prostate cancer refractory to established therapies. While there is an increasing body of survival and other data from retrospective analyses and prospective trials, there is no clear understanding of how best to predict therapy response and survival outcomes. ⋯ Our findings suggest that 177Lu-PSMA radioligand therapy provides a significant response rate with a low toxicity profile. The evidence promotes greater efficacy of radioligand therapy in predominantly lymph node metastatic castration-resistant prostate cancer, and in individuals with chemotherapy-naïve status and lower levels of baseline PSA.
