title: [Oncological results of active surveillance in prostate cancer: A retrospective multicentric cohort].
abstract: OBJECTIVE
  To report oncological outcomes of patients with prostate cancer undergoing active surveillance according to SURACAP criteria.
  
  
  METHODS
  This multicentric study included patients who were initially treated with active surveillance for localized prostate cancer according to the SURACAP criteria. The duration of active surveillance as well as the causes of discontinuing the protocol and the definitive pathological results of patients who further underwent radical prostatectomy were retrospectively evaluated. The predictors of discontinuing active surveillance were assessed using a univariable Cox Model. In addition, the predictive value of initial MRI was assessed for patients who performed such imagery.
  
  
  RESULTS
  Between 2007 and 2013, 80 patients were included, with a median age of 64 years [47-74]. Median follow-up was 52.9 months [24-108]. At 5 years follow-up, 43.4% patients were still under surveillance. Among patients that underwent surgery, 17.8% had an extra-capsular extension. The risk of discontinuing was not significantly greater for patients with tumor size of 2 or 3mm versus 1mm (HR=0.9 [0.46-1.75], P=0.763), 2 positives cores versus 1 (HR=0.98 [0.48-2.02], P=0.967), T2a vs. T1c stage (HR=2.18 [0.77-6.18], P=0.133), increased PSA level (HR=1 [0.96-1.15], P=0.975) or the patient's age (HR=1 [0.93-1.16], P=0.966). Among the 50 patients who performed initial MRI, the results of such imagery was not significantly associated to the risk of discontinuing active surveillance MRI (HR=1.49 [0.63-3.52], P=0.36).
  
  
  CONCLUSIONS
  Although this study reveals a high rate of release from active surveillance at 5 years, the rate of extra-capsular tumors reported in the group of patients that underwent surgery is among the lowest in literature.
