Abstract:
OBJECTIVETo investigate the cutoff value and significance of lymph node ratio (LNR) in oral squamous cell carcinoma.
METHODSThis retrospective study included 286 patients with oral cancer and pathological positive lymph nodes. Used time-dependent receiver operating characteristic (ROC) curves to determine which LNR best defines different risk groups of oral squamous cell carcinoma (OSCC) patients. All the variables were subjected to the univariate analysis, then only the variables that had prognostic potential were subjected to multivariate analysis by the COX proportional hazards regression model.
RESULTSThe cutoff value of LNR was 0.092. When LNR was greater than 0.092, the overall survival rate was 24.2%, when LNR was less than 0.092, the overall survival rate was 45.8% (P<0.05).
CONCLUSIONSLymph node ratio is a predictor of outcome in patients with oral squamous cell carcinoma, and the cutoff value is 0.092.
