The Impact of Blue Light Cystoscopy Use Among Nonmuscle Invasive Bladder Cancer Patients in an Equal Access Setting: Implications on Recurrence and Time to Recurrence.

ABSTRACT:

Introduction

Prior studies suggest that white light cystoscopy (WLC) alone can fail to detect cases of non-muscle invasive bladder cancer (NMIBC) vs. blue light cystoscopy (BLC). We describe bladder cancer outcomes and the impact of BLC among NMIBC patients in an equal access setting.

Materials and methods

We assessed 378 NMIBC patients within the Veterans Affairs system that had a CPT code for BLC from December 1, 2014 to December 31, 2020. We determined recurrence rates and time to recurrence prior to BLC (ie, after previous WLC if available) and following BLC. We used the Kaplan-Meier method to estimate event-free survival and Cox regression to determine association between BLC and recurrence, progression, and overall survival; and further, whether these outcomes differed
