Prognostic Factors and a Predictive Nomogram of Cancer-Specific Survival of Epithelial Ovarian Cancer Patients with Pelvic Exenteration Treatment

Optimal cutoff values determination of continuous variables and Kaplan–Meier curves stratified by the values using x-tile software. (a) Ages were split into two groups: ≤70 years old and ≥71 years old; (b) cutoff values of lymph nodes examined were 12 nodes and 25 nodes; (c) cutoff value of lymph nodes positive was 8 nodes; (d) LNR were categorized into three subgroups: (0, 0.03), (0.03, 0.32), and (0.32, 1.00). (e) LODDS were divided into three groups: (−2.25, −1.18), (−1.18, −0.25), and (−0.25, 2.26). (f) Threshold of tumor size was 38 mm.
