Purpose: We compared the effectiveness of narrow-band imaging (NBI) cystoscopy and white light cystoscopy (WLC) for detection of intravesical recurrence of bladder cancer.
Materials and Methods: We studied the positive predictive value (PPV) in the recurrent suspicious lesions in patients with nonmuscle invasive bladder cancer (NMIBC) for the 13 months of the follow-up from July 2016 to June 2017 with WLC and another 13 months from July 2017 to July 2018 with NBI, respectively. We also studied the second transurethral resection of bladder tumor (TURBT) free survival (STFS) and cancer-specific recurrence-free survival (CSRFS) with WLC and NBI in the 12 months of short-term follow-up.
Results: The total number of first TURBT patients in the follow-up was 164. Eighty patients were excluded. Among the 84 patients with NMIBC, WLC group was 43, NBI group was 41. Thirty-six patients had more than second TURBT. In 48 cases of patients with more than second TURBT, PPV of WLC and NBI was 81.8% and 61.5%, respectively. There was no statistically significance of PPV between the 2 groups (p=0.124). There were no pathological differences between the results about 1 year of follow-up patients with one of WLC or NBI (p=0.288). STFS was statistically significantly shorter in NBI (p=0.002), but there were no statistically significant difference in CSRFS.
Conclusions: NBI had made the bladder lesions detected early but had a low PPV for cancer recurrence within the bladder and there is no survival benefit.
