Narrow-band imaging in transoral laser surgery for early glottic cancer in relation to clinical outcome

Abstract

Background

The purpose of this study was to validate the prognostic value of adding narrow-band imaging (NBI) during transoral laser surgery (TLS) for early glottic cancer.

Methods

In 84 patients, 93 transoral laser resections were performed for carcinoma in situ (Tcis), T1, or T2 glottic cancer. TLS was preceded by intraoperative evaluation using traditional white-light imaging (WLI) in 51 cases. In 42 cases, NBI was used in addition to WLI. Local recurrence rate and recurrence-free survival were retrospectively compared between both groups.

Results

Local recurrences developed in 14% of the 93 cases: 12 of 51 patients (24%) were treated by TLS based on WLI alone, and in 1 of 42 patients (2%) in the NBI group (P < .01). Two-year recurrence-free survival was 82% in the WLI group and 98% in the NBI group (P < .05).

Conclusion

Additional use of NBI during TLS for early glottic cancer significantly improves clinical outcome.
