Prostate cancer antigen 3 (PCA3, also referred to as DD3) is a gene that expresses a non-coding RNA. PCA3 is only expressed in human prostate tissue, and the gene is highly overexpressed in prostate cancer.[3][4] Because of its restricted expression profile, the PCA3 RNA is useful as a tumor marker.[5]

Use as biomarker

urine samples, and it is possible that a combination of several urinary biomarkers will replace PSA in the future.[6]

Compared to serum PSA, PCA3 has a lower

PCA3 has been shown to be useful to predict the presence of malignancy in men undergoing repeat prostate biopsy.[9][10] This means that it could be useful clinically for a patient for whom digital rectal examination and PSA suggest possible prostate cancer, but the first prostate biopsy returns a normal result. This occurs in approximately 60% of cases, and on repeat testing, 20-40% have an abnormal biopsy result.[11]

Other uses that are being studied for PCA3 include its correlation with adverse tumor features such as tumor volume,

Gleason score) or extracapsular extension. These studies have so far produced conflicting results.[12][13][14]

Society and culture

A commercial kit called the Progensa PCA3 test is marketed by the Californian company Gen-Probe.[citation needed] Gen-Probe acquired rights to the PCA3 test from Diagnocure in 2003.[citation needed] In April 2012, Hologic bought Gen-Probe for $3.75 billion by cash.[15]

Discovery

PCA3 was discovered to be highly expressed by prostate cancer cells in 1999.[3][third-party source needed]
