Early prostate cancer antigen-2 (EPca-2)

Early prostate cancer antigen-2 (EPca-2), pronounced as /ɪərli prɒsteɪt kænsər æntɪdʒən tuː/, is a biomarker identified in the early stages of prostate cancer. The etymology of the term is derived from its role in the early detection of prostate cancer.

Definition

EPca-2 is a protein that is overexpressed in prostate cancer cells. It is used as a biomarker to detect the presence of prostate cancer at an early stage. The detection of EPca-2 can be done through a blood test or a biopsy.

History

The discovery of EPca-2 was made in the late 20th century as part of the ongoing research into early detection methods for prostate cancer. The identification of this biomarker has significantly improved the early detection and treatment of prostate cancer.

Clinical Significance

The presence of EPca-2 in the blood or tissue samples can indicate the presence of prostate cancer. It is particularly useful in detecting prostate cancer at an early stage when the disease is most treatable. The detection of EPca-2 is often used in conjunction with other tests such as the Prostate-Specific Antigen (PSA) test.
