Prostate cancer screening

There is lack of data from randomised control trials which show the benefit to harm ratio of using the PSA test for prostate cancer screening. But evidence from Europe has shown that PSA test can be used to save lives but it is unknown how many cases would be diagnosed and subsequently overtreated (1).

  • interim results from a large European randomised controlled trial (2) and a large US study show that screening with prostate-specific antigen (PSA) testing (combined with digital rectal examination [DRE] in the US study) (3) detects many more cancers than usual care
    • in US, before the use of PSA test (pre PSA era) the life time risk of prostate cancer diagnosis was around 8% while it has risen to 19% in the current PSA era (1)
  • however a review notes caution and states
    • "..the value of prostate cancer screening is still unclear.... whether or not this (results of the studies mentioned) translates into a survival benefit from prostate cancer remains uncertain.."(4)
      • interim results from the European study (n=162,243) suggest that, over nine years, 1,410 men would need to be screened with PSA testing (and 48 additional men with cancer would need to be treated) to prevent one death from prostate cancer
  • a US cross-sectional study (5) noted:
    • Question Was the 2012 US Preventive Services Task Force (USPSTF) Grade D recommendation against prostate-specific antigen (PSA) screening for all men associated with prostate cancer–specific mortality (PCSM)?
    • Findings This cross-sectional study found statistically significant changes in PCSM rates that coincided with the change in the screening guideline; PCSM rates were decreasing prior to the recommendation and remained steady after the recommendation.
    • Meaning This study suggests that the change in the USPSTF PSA screening guideline to a Grade D recommendation against PSA screening for all men may have been associated with the stagnancy of PCSM rates.

The national screening committee recommends that screening programmes to detect prostate cancer should not be introduced at present in the UK. The Prostate Cancer Risk Management Programme was introduced in place of this with the aim of providing good quality information about the advantages and disadvantages of the PSA test. This in turn would help men who consider undergoing this test make an informed choice (1).
