title: [Bladder tumor targeting by Hexvix(®) fluorescence: 4 years results after prospective monocentric evaluation].
abstract: OBJECTIVE
  Prospective evaluation of bladder tumor targeting by Hexvix(®) fluorescence.
  
  
  METHODS
  From September 2008 to April 2012, 107 patients have been evaluated using Hexvix(®) technique (blue light) for typically papillary bladder tumor or suspected bladder tumor. Clinical and pathological data have been collected prospectively and patients have been classified using EORTC score.
  
  
  RESULTS
  From the 107 patients, 67 have been identified with bladder cancer and 328 samples have shown positive fluorescence in blue light. Compared to white light, 13 additional tumors have been diagnosed by Hexvix(®) for 11 patients: Cis (n=6), LMP (n=3), pTa low grade (n=3), pT1 low grade (n=1) (P=0.003). The false positive rate for Hexvix(®) was 53.4% versus 52% for white light. Previous TCC history, multifocality and EORTC score for recurrence and progression have been associated with better bladder cancer targeting by Hexvix(®) (P=0.007; P=0.01; P=0.03; P=0.04).
  
  
  CONCLUSIONS
  In our experience, Hexvix(®) targeting was associated with better diagnosis for bladder cancer with 9% (13/144) of new positive samples (P=0.003). In our study, false positive rate is a critical point (53.4%). Multifocality, previous TCC, and EORTC score for recurrence and progression might allow selecting patients to be targeted by Hexvix(®).
