title: Watchful waiting and health related quality of life for patients with localized prostate cancer: data from CaPSURE.
abstract: OBJECTIVE
  Watchful waiting is an alternative to active treatment for men with low risk prostate cancer but it is unclear how health related quality of life (HRQoL) may change over time for men who select this option. We report on HRQoL in men with localized prostate cancer who selected watchful waiting.
  
  
  METHODS
  HRQoL outcomes were reviewed for 310 men diagnosed with prostate cancer from 1990 to 2001 within Cancer of the Prostate Strategic Urological Research Endeavor who chose watchful waiting. The UCLA Prostate Cancer Index and RAND 36-Item Health Survey were completed at enrollment and approximately every 6 months. A random slopes model was developed to assess time trends in HRQoL for up to 5 years after diagnosis, adjusting for age at diagnosis and specific comorbidities.
  
  
  RESULTS
  Significant decreases with time were observed in 7 domains of the RAND 36-Item Health Survey and 4 of the UCLA Prostate Cancer Index scales.
  
  
  CONCLUSIONS
  Men with prostate cancer who chose watchful waiting in the current study had better or similar HRQoL outcomes compared to men without prostate cancer at the start of the study. Many of these scores were significantly affected by increasing age and decreased with time. The physical domain scores as well as sexual function scores decreased more than expected from the aging process alone.
