title: Analysis of prognostic factors for patients with leiomyoma treated with uterine arterial embolization.
abstract: OBJECTIVE
  The objective of the study was to describe a clinically useful factors index predicting long-term efficacy of uterine artery embolization (UAE).
  
  
  METHODS
  Newly diagnosed patients with uterine leiomyoma wishing to retain their uterus underwent UAE at our institution. Clinical demographics and 4 prognostic factors were recovered from the medical record. A regrowth-free interval (RFI) was calculated for all patients based on leiomyoma regrowth or recurrence of any previously reported symptoms. RFI by prognostic factor was analyzed by the Kaplan-Meier method.
  
  
  RESULTS
  Forty-three patients were identified. Two prognostic factors were identified by multivariate analysis: vascularity (dichotomized as hypervascular vs hypovascular; RFI at 2 years, 80% vs 20%, P = .001) and number of nodules (solitary vs multiple; RFI at 2 years, 72% vs 25% at 2 years, P = .001)
  
  
  CONCLUSIONS
  UAE success may be predicted by 2 preoperative parameters. Further investigation is warranted.
