Though, when focusing on the potential factors associated with progression and survival ( Table 4 ), the Cox proportional hazards regression analysis showed lymphadenectomy not significantly influencing DFS (hazard ratio [HR]=0.59; 95% CI=0.32–1.08; univariate analysis p=0.09), while a borderline significance was shown for DSS (HR=0.14; 95% CI=0.02–1.21; multivariable analysis p=0.07).
