Management of cervical lymph nodes for cN0 advanced glottic laryngeal carcinoma and its long-term results

Abstract

The overall metastatic rate of N0 GLC was 14.6%. T staging and pathological classification were the risk factors for LNM. Metastatic rates for levels II, III, and IV were 10.2%, 14.6%, and 2.5%, respectively. Approximate 4.2% of patients experienced LNM with no recurrence of laryngeal cancer. Overall 3- and 5-year survival rates were 85% and 80%, respectively, compared with 66% and 57%, respectively, among patients with LNM. The inter-group survival curve comparison was statistically significant (p = 0.012).
