OBJECTIVE: Assess the impact of NBI modality on 1-yr non-muscle-invasive BCa (NMIBC) recurrence risk.
DESIGN, SETTING, AND PARTICIPANTS: Consecutive patients with overt or suspected BCa were included in a prospective study powered to test a 10% difference in 1-yr recurrence risk in favor of cases submitted to NBI TUR. Excluding patients with muscle-invasive BCa, negative pathologic examination, or without follow-up, the study population was composed of 148 subjects randomized from August 2009 to September 2010 to NBI TUR (76 cases) or white light (WL) TUR (72 cases).
INTERVENTION: TUR was performed in NBI or standard WL modality.
MEASUREMENTS: The 1-yr recurrence risks in NBI or WL TUR groups were compared using odds ratio (OR) point and interval estimates derived from logistic regression modeling.
RESULTS AND LIMITATIONS: The 1-yr recurrence-risk was 25 of 76 patients (32.9%) in the NBI and 37 of 72 patients (51.4%) in the WL group (OR=0.62; p=0.0141). Simple and multiple logistic regression analyses provided similar OR points and interval estimates.
CONCLUSIONS: TUR performed in the NBI modality reduces the recurrence risk of NMIBC by at least 10% at 1 yr.
