lymph node
In the multivariate analysis, a lymph node (LN) ratio of 0.113 or higher was a significant poor prognostic factor for OS (hazard ratio [HR] 1.89; 95% confidence interval [CI] 1.17-3.05; p  =  0.009), DSS (HR 2.17; 95% CI 1.29-3.64; p  =  0.003), and DFS (HR, 2.24; 95% CI 1.12-4.52; p  =  0.024) in stage 4 hypopharyngeal cancer.
