Lymph node density (LND) and LODDS were calculated for all the patients and classified according to American Joint Committee on Cancer (AJCC) pN staging. Thresholds for LND (24% and 46%) and LODDS (\u22120.75 and 0) were established. Multivariate analysis of various cofactors was done with overall survival (OS) as a dependent factor.
