title: Predictors of quality of life after radical treatment for prostate cancer.
abstract: BACKGROUND
  The usual treatment options for clinically localized prostate cancer carry a significant risk of lasting side effects, including urinary, bowel, and sexual dysfunction, that can alter overall the patient's quality of life. The aim of this research is to evaluate the impact of treatment timing (age at time of treatment, follow-up duration, age at time of follow-up), pretreatment tumor characteristics (clinical stage, Gleason score, PSA), and posttreatment outcomes (hormonal status, biochemical recurrence), on health-related quality of life (HRQOL) among men who had undergone radical treatment for prostate cancer.
  
  
  METHODS
  595 patients with prostate cancer who had undergone either radical prostatectomy or external beam radiation as primary therapy between 1988 and 2000 were selected for this retrospective, cross-sectional study. The enrolled subjects were asked to complete the Italian validated version of University of California-Los Angeles Prostate Cancer Index. Clinical parameters, hormone therapy status and posttreatment outcomes were considered to perform uni- and multivariate analyses.
  
  
  RESULTS
  Both uni- and multivariate analyses demonstrated that timing of radical treatment is a critical predictive factor for sexual activity. Pretreatment tumor characteristics had a significant impact on urinary function, urinary bother and sexual function. Hormone treatment exclusively influenced sexual function and sexual bother, while biochemical recurrence can also worsen urinary symptoms and urinary bother.
  
  
  CONCLUSIONS
  Our findings suggest that treatment timing, pretreatment tumor characteristics and posttreatment outcomes may have an impact on HRQOL in patients who have undergone radical treatment for prostate cancer: all these items should be considered in order to achieve an accurate interpretation of prostate cancer treatment outcomes.
