In univariable Cox regression analysis for CSS, eleven factors (age, sex, histologic grade, marital status, T stage, N stage, M stage, AJCC TMN stage, surgical approach, radiotherapy, lymph node ratio, and tumor size) reached statistical significance. Then, above eleven factors were included in the multivariate Cox analysis.
