Prognostic factors determining survival after extrapelvic recurrence in endometrioid type endometrial cancer

Objective: To define the factors that determine survival after extrapelvic recurrence in patients with endometrioid type endometrial cancer (EC).objective Materials and methods: Clinicopathological and survival data of surgically treated endometrioid type EC patients who recurred outside pelvis were reviewed. Patients who had non-endometrioid tumor, sarcomatous component in the final pathology and synchronous tumor were excluded. The period from surgery to recurrence was defined as time to recurrence (TTR) and the period from recurrence to death or last visit was defined as post-recurrence survival (PRS). Results: Sixty-six patients with extrapelvic recurrence were included in the study. No residual disease was achieved in all patients at initial surgery. Median TTR was 18 months (range, 2–84). Recurrence developed within 1 year in 24 (36.4%) patients and between 13 and 24 months in 22 (33.3%) patients. Fifty-three of 66 patients (80.3%) had extraabdominal recurrence. The 2-year PRS of the all cohort with extrapelvic recurrence was 56%. In the univariate analysis, advanced FIGO stage, lymph node metastasis, adnexal metastasis and short TTR were associated with diminished PRS (p
