New prostate cancer staging guidelines improved evidence-based test use and reduced racial disparities in staging evaluations for men with incident prostate cancer.

Area of Science:

  • Urology
  • Oncology
  • Health Services Research

Background:

  • Clinical practice guidelines for prostate cancer staging were published in 1995 by the National Comprehensive Cancer Network, American Urological Association, and American College of Radiology.
  • These guidelines aimed to standardize the staging evaluation for men with incident prostate cancer.

Purpose of the Study:

  • To compare prostate cancer staging practices before and after the 1995 guideline publication.
  • To assess for racial differences in staging evaluation among men with prostate cancer.

Main Methods:

  • A retrospective cohort study analyzed 96,986 men with incident prostate cancer using Surveillance, Epidemiology, and End Results-Medicare linked data.
  • Data from 1991-1994 (pre-guidelines) were compared to 1995-1999 (post-guidelines).

  • Evaluated use of bone scan and pelvic imaging (CT or MRI) in relation to guideline criteria and race.

    • Main Results:

    • Post-guidelines, bone scan use decreased in men meeting criteria but decreased substantially in those not meeting criteria.
    • Pelvic imaging rates increased for men meeting criteria and decreased for those not meeting criteria after 1995.
    • Racial disparities in staging test use among men meeting guideline criteria were eliminated post-1995, with Black men previously less likely to undergo bone scan or pelvic imaging.

    Conclusions:

    • Publication of staging guidelines led to increased evidence-based use of staging tests for prostate cancer.
    • A significant decrease in racial disparity in staging evaluation was observed after guideline implementation.
    • These findings highlight the positive impact of evidence-based guidelines on clinical practice and health equity in prostate cancer care.
