Purpose
The extranodal extension (ENE) in head and neck squamous cell carcinoma (HNSCC) is a potential poor prognostic factor. Clinical ENE (cENE) was incorporated in the HNSCC staging system in the 8th edition of AJCC. There is not much evidence to support the treatment of HNSCC with cN3b with radiotherapy in radical intent. This study aims to assess the treatment outcome in patients of HNSCC with cN3b disease treated with definitive radiotherapy.
Method
Forty-five HNSCC patients with cN3b disease treated with definitive radiotherapy with or without concurrent chemotherapy between January 2018 to December 2018 were retrospectively evaluated.
Results
The median age of the study patients was 60 years (40–75years). Only 35 patients (77.8%) could complete the prescribed course of treatment, and the leading common cause of non-completion was treatment-related toxicities. After a median follow-up period of 9.3 months (range 2–33), the median OS and PFS were 22.6 months and 7.2 months, respectively. Fourteen patients (31.1%) in our study developed grade III/IV mucositis, and 11 (24.4%) developed severe grade III/IV dermatitis. The locoregional failure constituted 24 patients (53.3%).
Conclusion
The treatment outcome of HNSCC with cN3b disease is inferior. A personalized and subjective approach should be undertaken before choosing radiotherapy with a radical intent in this group of patients.
