Abstract

OBJECTIVES: Early detection of local recurrences in patients with head and neck squamous cell carcinoma (HNSCC) is crucial for long-term survival. Aim of this study was to compare white light (WL) imaging with narrow band imaging (NBI) during flexible laryngoscopy for detection of local recurrences and evaluate the effects on clinical outcome in patients with HNSCC treated with radiotherapy ± chemotherapy ((C)RT).

DESIGN: Prospective randomised controlled trial.

SETTING: Tertiary head and neck oncologic center.

PARTICIPANTS: 257 patients without residual disease after (C)RT were randomised in a WL group (n = 120) or WL-NBI group (n = 137) and followed for 24 months.

MAIN OUTCOME MEASURES: Local recurrence rate and overall survival, disease-specific survival, disease-free survival and local recurrence-free survival were compared between both groups.

RESULTS: Detection rate of local recurrences was the same in both groups: 11.7% in WL-NBI and 10.0% in WL (p > 0.05). Overall survival (WL: 88.3%, WL-NBI: 87.6%), disease-specific survival (WL: 86.7%, NBI: 83.9%), disease-free survival (WL: 85.0%, WL-NBI: 83.2%) and local recurrence-free survival (WL: 90.0%, WL-NBI: 89.1%) showed no superiority in the WL-NBI group (p > 0.05).

CONCLUSIONS: Local recurrence rates are relatively low in the first 24 months after (C)RT for HNSCC. WL-NBI did not improve the detection of local recurrences nor the survival compared to WL.

TRIAL REGISTRATION: This randomised clinical trial was registered at the research register UMCG with the number 201500918.
