Overview

Retrospective analysis evaluates the link between PSA testing and curative treatment in elderly men, suggesting implications for access to care.

Key Points

  • This study aimed to evaluate the association between regular PSA testing and the receipt of curative treatment for prostate cancer among elderly men in Japan.
  • Conducted a retrospective analysis using claims data from the National Health Insurance system in Saga Prefecture (March 2014 - March 2022)
  • Categorized patients into PSA testing and non-PSA testing groups
  • Applied multivariable logistic regression to identify factors associated with curative treatment.
  • Among 2,200 patients, 33.5% underwent PSA testing and 32.2% received curative treatment.
  • The proportion receiving curative treatment was higher in the PSA testing group (36.4% vs. 30.1%, p < 0.001).
  • Age (OR = 0.85), PSA testing (OR = 1.53), and participation in Specific Health Checkups (OR = 1.64) were independently associated with curative treatment.
