Prognostic factors predicting postoperative survival of 
OS/DFS
REGRESSION, METASTASIS, STD
We started identifying prognostic factors for postoperative survival by interrogating association between each factor and DFS at Log‐rank analysis of prognostic factors for DFS and OSMultivariate Cox regression analysis of OS/DFS prognostic factorsAbbreviation: NI, not included in analysis.The same approach was applied to identify OS‐associated clinicohistologic features, which included FIGO stage, pathological type, vascular invasion, cervical junction invasion, myometrial invasion, parametrial involvement, vaginal fornix involvement, PLN metastasis, and history of STD per univariate analysis. Multivariate Cox regression analysis showed that cervical myometrial invasion, pathological type, and history of STD were independent prognostic factors for postoperative OS (Table
