<h2 id="use-as-biomarker">Use as biomarker</h2> <p>The most frequently used <a href="/facts/Biomarker/nk2LgXtq">biomarker</a> for prostate cancer today is the <a href="/facts/Blood_serum/a22tvug9">serum</a> level of <a href="/facts/Prostate-specific_antigen/HaylgTdR">prostate-specific antigen</a> (PSA), or derived measurements. However, since PSA is <a href="/facts/Prostate/mrBdSsf7">prostate</a>-specific but not <a href="/facts/Cancer/PVW6n1D0">cancer</a>-specific, it is an imperfect biomarker. For example, PSA can increase in older men with <a href="/facts/Benign_prostatic_hyperplasia/ocGSCVK9">benign prostatic hyperplasia</a>. Several new biomarkers are being investigated to improve the diagnosis of prostate cancer. Some of these can be measured in <a href="/facts/Urine_sample/PeS2UfIG">urine samples</a>, and it is possible that a combination of several urinary biomarkers will replace PSA in the future.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> </p><p>Compared to serum PSA, PCA3 has a lower <a href="/facts/Sensitivity_and_specificity/pzc9qfdz">sensitivity</a> but a higher <a href="/facts/Sensitivity_and_specificity/pzc9qfdz">specificity</a> and a better <a href="/facts/Positive_predictive_value/G238SK2V">positive</a> and <a href="/facts/Negative_predictive_value/G238SK2V">negative predictive value</a>.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> It is independent of prostate volume, whereas PSA is not.<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a> It should be measured in the first portion of urine after <a href="/facts/Prostate_massage/2484Nzap">prostate massage</a> with <a href="/facts/Digital_rectal_examination/zYJcnBxD">digital rectal examination</a>.<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> </p><p>PCA3 has been shown to be useful to predict the presence of malignancy in men undergoing repeat <a href="/facts/Prostate_biopsy/0M3YtH1w">prostate biopsy</a>.<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a><a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a> 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.
