Prostate-specific membrane antigen (PSMA) is highly expressed on prostate cancer (PC) cells and can be detected in tumors using positron emission tomography imaging. Even though clinical features predict different stages of PC progression, the application of imaging to guide treatment is still evolving but gaining substantial evidence for the targeting of PSMA. With clinical research shifting paradigms for the treatment of metastatic castration-resistant prostate cancer (mCRPC), novel treatment options require adoption and effective application into clinical practice. PSMA has become an appealing target for diagnostic agents for imaging and therapeutic agents to treat mCRPC. Radionuclide emitters are being used for both cell surface expression of PSMA and the tumor microenvironment, and research has proven the therapeutic efficacy of PSMA-directed radioligand therapy (RLT).
In this educational activity, two experts will examine the role and rationale for PSMA targeted therapies and diagnostics—jointly known as theragnostics—as a revolutionary new approach to treating patients with advanced prostate cancer and will evaluate clinical trial data for PSMA-targeted RLT.
