摘要

Prostate-specific membrane antigen (PSMA) is upregulated in prostate cancer cells relative to other cells. The increased expression and enzymatic activity of PSMA in high-stage disease confers a selective advantage on such cells, contributing to their increased proliferation, the tendency to metastasize and the development of a castration-resistant phenotype. The decades of radiobiochemical advances in the development of PSMA targeting radiolabelled ligands has led to the subsequent FDA approval of a number of radiotracers and radiotherapeutics for clinical use. Novel developments in therapeutic advances using PSMA-based combinatorial approaches include PSMA-targeted antibody–drug conjugates and PSMA-targeted radionuclide payloads. Combining and sequencing some of these strategies with standard therapy options such as surgery, radiotherapy and androgen receptor pathway inhibitors could improve patient outcomes. Immunotherapy and chimeric antigen receptor T cell therapy are relevant to PSMA-based therapies as PSMA can serve as a specific target antigen for these treatments, enabling precise tumour recognition and enhanced efficacy of prostate cancer therapies.
