In patients with metastatic cutaneous head and neck squamous cell carcinoma to cervical lymph nodes, the extent of neck dissection does not influence outcome

Abstract

AbstractBackground:This study aimed to compare recurrence and survival in patients undergoing either selective neck dissection or modified radical neck dissection to treat metastatic cutaneous head and neck squamous cell carcinoma to the cervical lymph nodes (levels I–V) only.Methods:Twenty-eight year, retrospective analysis of a prospectively maintained database from a tertiary referral hospital, with a minimum follow up of two years.Results:There were 122 eligible patients: 96 males (79 per cent) and 26 (21 per cent) females (median age, 66 years). Sixty-six patients (54 per cent) underwent selective neck dissection and 56 (46 per cent) modified radical neck dissection. The former patients had a lower rate of regional recurrence compared with the latter (17 vs 23 per cent, respectively). There was no significant difference in five-year overall survival (61 vs 57 per cent, respectively) or five-year disease-free survival (74 vs 60 per cent, respectively), comparing the two groups. Overall survival and disease-free survival were significantly improved by the addition of adjuvant radiotherapy.Conclusion:We found no difference in outcome in patients undergoing selective versus modified radical neck dissection. Adjuvant radiotherapy significantly improved outcome.
