The PCA3 test is a molecular prognostic test that helps to determine whether a prostate biopsy is necessary. It involves examining a urine sample to look for the prostate cancer antigen 3 (PCA3) gene. This biomarker can reveal whether the patient is at low or high risk of developing prostate cancer.
The PCA3 test isn’t a substitute for the prostate-specific antigen (PSA) test. Rather, it’s an additional tool that helps determine whether a prostate biopsy is truly needed for a diagnosis of prostate cancer in a man already suspected of having this disease. Contrary to PSA, PCA3 is a gene that is linked specifically to prostate cancer. It’s only produced by prostate cancer cells and is not dependent on prostate size. A PCA3 test is more effective than a PSA test at differentiating prostate cancer from benign (non-cancerous) prostate diseases such as benign prostate hyperplasia (an enlarged prostate) or prostatitis (a prostate infection). When used in conjunction with a PSA test, the PCA3 test provides key information for determining whether a prostate biopsy is necessary.
