Flowchart shows study participant inclusion and exclusion. Consecutive patients who underwent surgery for uterine endometrial cancer between January 2013 and September 2016 at this hospital were recruited. Thirty-six patients were excluded due to incomplete preoperative assessment data, including lack of pre-op EB data (n = 9), lack of FS (n = 26), or indeterminate intraoperative staging by frozen section (n = 1). Patients who underwent preoperative hormonal therapy (n = 1) or neoadjuvant chemotherapy (n = 1), or had coexisting cancer of other organs, including uterine cervical cancer and non-endometrioid ovarian cancer (n = 21), were also excluded. FS: frozen section. Pre-op EB: preoperative endometrial biopsy
