Prostate-specific antigen testing for prostate cancer: Time to reconsider the approach to screening

Prostate cancer is now the most common cancer in men in Australia. Men should be aware of the potential risk of significant prostate cancer despite the lack of symptoms. Screening for prostate cancer using prostate-specific antigen (PSA) has been controversial. General practice guidelines can be confusing leading to men not being tested for prostate cancer. Reasons cited include overdiagnosis and overtreatment with associated morbidity.

This article aims to highlight the current evidence for PSA testing and advocate for updating outdated guidelines and resources.

Current evidence shows that a risk-stratified approach to PSA screening helps to assess that risk. Recent studies show improved survival rates with early intervention compared with observation/delayed treatment. Imaging, including magnetic resonance imaging and prostate-specific membrane antigen positron emission tomography, have made a significant difference in the management pathway. Biopsy techniques have progressed to minimise sepsis risk. Quality and patient-reported outcomes registry data highlight the increased use of active surveillance in patients with low to intermediate risk of prostate cancer, reducing treatment-associated harms in men with low risk of progression. There have also been improvements in medical therapeutics for advanced disease.
