Abstract

© 2018 Wiley Periodicals, Inc. Background: The purpose of this study is to evaluate the prognostic significance of nodes with extracapsular spread (ECS) in patients treated with a planned neck dissection after chemoradiotherapy. Methods: We carried out a retrospective study of 109 cN+ patients who achieved a complete response in the primary location after chemoradiotherapy and treated with a planned neck dissection. Results: The 5-year disease-specific survival for patients without residual metastatic nodes in the neck dissection (pN0, n = 69) was 75.7% (95% CI: 64.4%-87.0%). For patients with metastatic nodes without ECS (pN+/ECS-negative, n = 17), the corresponding figure was 74.0% (95% CI: 48.2%-99.8%), and for patients with metastatic neck nodes with ECS (pN+/ECS-positive, n = 23) it was 8.7% (95% CI: 0.0%-24.3%) (P =.0001). Conclusion: The presence of ECS in the pathologic study of the planned neck dissections carried out after chemoradiotherapy in patients with human papillomavirus-negative (HPV-negative) head and neck squamous cell carcinoma (SCC) allows identification of a group of patients with a high risk of failure.
