    Prostate cancer is one of the most common malignant tumors in European and American countries
    .

    With the improvement of China's economic level and the change of residents' life>
    .

    PSMA is not only highly expressed in advanced and castration-resistant prostate cancer, but the large extracellular domain makes it a perfect target for immune methods
    .

    In addition, the results of PSMA targeted radionuclide therapy also confirmed that it is an ideal target for the diagnosis and treatment of prostate cancer
    .

    For the treatment of advanced prostate cancer, androgen deprivation therapy (ADT) is still the first-line therapy, but advanced prostate cancer often develops metastasis or castration resistance, and then develops into castration-resistant prostate cancer (CRPC, Castrate-Resistant Prostate Cancer)
    .

    For CRPC, androgen receptor blockers (AR) such as abiraterone and enzalutamide have been widely used clinically, but the remission rate is limited
    .

    Therefore, more therapies for PSMA need to be explored
    .

    At present, immunotherapy targeting PSMA has entered the clinic, and it is expected to provide new drug options for patients with advanced castration-resistant prostate cancer in the future
    .

    Targeted PSMA immunotherapy is mainly divided into the following categories: antibody-drug conjugates (ADC), chimeric antigen receptor T cells (CAR-T), and bispecific T cell redirection therapy
    .
