Prostate-specific membrane antigen (PSMA) testing aids in identifying, staging, and monitoring metastatic prostate cancer. Its evolution offers promising roles in imaging and therapy for recurrent or advanced disease.

Area of Science:

  • Oncology
  • Biochemistry

Background:

  • Prostate cancer is a leading cancer diagnosis and cause of cancer death in men.
  • Prostate cancer exhibits a wide range of biological behaviors, from indolent to aggressive.
  • Prostate-specific membrane antigen (PSMA) is a key prognostic proliferation marker.

Purpose of the Study:

  • To review the historical evolution, current benefits, and limitations of PSMA testing.
  • To evaluate the future value of PSMA in prostate cancer management.
  • To explore PSMA's role in understanding prostate cancer's diverse biological behaviors.

Main Methods:

  • Review of studies on PSMA detection in serum and seminal fluid.
  • Analysis of reverse transcriptase-polymerase chain reaction (RT-PCR) and immunoscintigraphy assays.

  • Examination of immunohistochemical assays for PSMA expression.

    • Main Results:

    • PSMA is primarily expressed in benign and cancerous prostatic epithelial cells.
    • PSMA is upregulated in hormone-resistant, metastatic, recurrent, or extending prostate cancer.
    • Serum PSMA detection aids in identifying, staging, and monitoring metastatic prostate cancer.

    Conclusions:

    • PSMA testing has evolved significantly, offering valuable insights into prostate cancer.
    • Current PSMA detection methods show promise for managing metastatic and recurrent disease.
    • PSMA holds potential for targeted imaging and therapy in advanced prostate cancer.
