title: Prostate cancer nomograms: an update.
abstract: OBJECTIVE
  Several nomograms have been developed to predict outcomes related to prostate cancer (PCa).
  
  
  METHODS
  We provide a descriptive and an analytic comparison of nomograms. Further, we report a set of recent PCa nomograms, in which we recorded predictor variables, number of patients used to develop each nomogram, and nomogram-specific features. Moreover, accuracy estimates and type of validation are considered.
  
  
  RESULTS
  Our findings suggest a demand for updated nomograms in selected fields of PCa outcomes. Moreover, an increasing number of nomograms address important end points such as prostate-specific antigen recurrence, distant metastases, or androgen-independent PCa-specific survival.
  
  
  CONCLUSIONS
  Our results suggest that nomograms are available for many PCa-related outcomes. They represent a valid methodologic approach if correct criteria are met.
