Exp (β) – hazard ratio; CI – confidence interval; pT tumor stage – pathological primary tumor stage; ‘−’ – variables not in the multivariate model due to lack of significance (>0.10) on univariate analysis; N stage – regional lymph node stage; M stage – distant metastasis stage; Minimally invasive – limited vascular invasion ( | ||||||||
