title: Analysis of risk factors associated with recurrence of nasopharyngeal angiofibroma.
abstract: OBJECTIVE
  Surgical outcomes and prognostic factors were analyzed to determine what factors increase the probability of juvenile nasopharyngeal angiofibroma (JNA) recurrence.
  
  
  METHODS
  Ninety-seven males with JNA were diagnosed and underwent surgery at Fudan University Affiliated Eye, Ear, Nose and Throat Hospital from 1997 to 2006. Clinical data were extracted from medical records and were used in the statistical analysis.
  
  
  RESULTS
  The total recurrence rate of JNA was 39.2% after the initial surgery. A patient whose tumour staging was higher was more likely to have a recurrence than a patient whose tumour staging was lower (p = .0031). The recurrence rates in two groups (age >or= 18 years group and < 18 years group) were 26.8% and 48.2%, respectively (p = .03). The recurrence rates with tumour size < 4 cm and >or= 4 cm were 21.7% and 54.9%, respectively (p = .0008).
  
  
  CONCLUSIONS
  The significant predictors of recurrence in our study were age at diagnosis, tumour size, and Radkowski classification.
