Abstract

Metastatic castration‐resistant prostate cancer (mCRPC) represents a condition of pro-gressive disease in spite of androgen deprivation therapy (ADT), with a broad spectrum of mani-festations ranging from no symptoms to severe debilitation due to bone or visceral metastatization. The management of mCRPC has been profoundly modified by introducing novel therapeutic tools such as antiandrogen drugs (i.e., abiraterone acetate and enzalutamide), immunotherapy through sipuleucel‐T, and targeted alpha therapy (TAT). This variety of approaches calls for unmet need of biomarkers suitable for patients’ pre‐treatment selection and prognostic stratification. In this sce-nario, imaging with positron emission computed tomography (PET/CT) presents great and still unexplored potential to detect specific molecular and metabolic signatures, some of whom, such as the prostate specific membrane antigen (PSMA), can also be exploited as therapeutic targets, thus combining diagnosis and therapy in the so‐called “theranostic” approach. In this review, we per-formed a web‐based and desktop literature research to investigate the prognostic and theranostic potential of several PET imaging probes, such as18F‐FDG,18F‐choline and68Ga‐PSMA‐11, also covering the emerging tracers still in a pre‐clinical phase (e.g., PARP‐inhibitors’ analogs and the radioligands binding to gastrin releasing peptide receptors/GRPR), highlighting their potential for defining personalized care pathways in mCRPC.
