Background: A retrospective study was aimed to establish the eventual impact of narrow band imaging (NBI) cystos copy over the short term residual tumorsâ rate determined during the first follow-up endoscopic control in newly determined non-muscle invasive bladder cancer (NMIBC) cases.
Methods: 68 patients were found with NMIBC by means of both white light cystoscopy (WLC) and NBI. A follow-up using both investigation modalities was performed at 3 months from the initial procedure in 67 cases (one was lost from follow-up). RESULTS concerning the short termer currences were retrospectively compared to those obtain ending a similar series of 67 patients previously diagnosed and treated by means of classical WLC and resection only.
Results: The short term residual tumorsâ rate established during the first follow-up cystoscopy was lower in the study group initially benefiting from the NBI mode by comparison to the WLC control series (4.5% versus 11.9%). When drawing a parallel with the tumor map location outlined during the initial procedure, the most important differences were emphasized concerning other site recurrences (3%versus 8.95%).
Conclusions: NBI cystoscopy and resection displayed a substantially favorable influence over the short termoncologic outcome in newly diagnosed NMIBC cases when compared to the standard protocol.
