title: Is quality of life different for men with erectile dysfunction and prostate cancer compared to men with erectile dysfunction due to other causes? Results from the ExCEED data base.
abstract: OBJECTIVE
  To our knowledge the relationship between the underlying etiology of erectile dysfunction and its impact on health related quality of life has not been studied. Such a study is important for men with prostate cancer, as the potential negative quality of life impact of erectile dysfunction may affect clinical decision making in newly diagnosed disease. We compare health related quality of life in impotent men with prostate cancer to that of impotent men without prostate cancer using the Exploratory and Comprehensive Evaluation of Erectile Dysfunction (ExCEED, TAP Pharmaceutical Products, Inc., Lake Forest, Illinois) data base, which is a multicenter, observational disease registry of men with erectile dysfunction.
  
  
  METHODS
  The cohort included 168 men in ExCEED who had baseline health related quality of life measurement. Of these men 47 reported a history of prostate cancer while 121 did not. Appropriate univariate and multivariate analyses were performed comparing health related quality of life outcomes between impotent men with and without prostate cancer.
  
  
  RESULTS
  Men with erectile dysfunction and prostate cancer had worse sexual self-efficacy, erectile function, intercourse satisfaction and orgasmic function than those with erectile dysfunction without prostate cancer (all p <0.001). However, men with erectile dysfunction and prostate cancer experienced less psychological impact of erectile dysfunction on sexual experience (p = 0.05) and emotional life (p = 0.03) than those with erectile dysfunction without prostate cancer. The findings regarding the psychological impact of erectile dysfunction persisted in multivariate linear regression models.
  
  
  CONCLUSIONS
  Men with erectile dysfunction and prostate cancer appear to have better disease specific health related quality of life than those with erectile dysfunction and no history of prostate cancer. This finding has important ramifications for clinicians when counseling patients newly diagnosed with prostate cancer and also when treating patients who present with erectile dysfunction of various etiologies.
