Objectives: Grade 3 endometrioid adenocarcinomas (G3 EAC), type two endometrial carcinomas (Type 2 EC), and also
uterine carcinosarcomas (UCS) are considered as high-grade endometrial adenocarcinomas. The aim of this study was to
compare the clinicopathologic features and survival of patients with UCS, G3 EAC, Type2 EC.
Material and methods: We included two hundred and thirty-five patients in this study. Patients were divided into three
groups according to the type of tumor as uterine G3 EAC (group 1, n = 62), Type 2 EC (serous, clear and mixed types; group 2,
n = 93), and UCS (group 3, n = 80). We compared the groups according to age, initial symptom, surgical approach, stage,
myometrial invasion (MI), lymph node invasion (LNI), lymphovascular space invasion (LVSI), adjuvant therapy, and survival.
When comparing the survival outcomes the Kaplan-Meier analysis was performed.
Results: The groups were similar according to age, menopausal status, nulliparity, initial symptoms, stage, LVSI, and LNI.
Positive cytology was determined significantly more in group 3. There was a significant difference between the groups in
terms of myometrial invasion degree. Optimal cytoreduction was similar among the groups. The primary adjuvant treatment
was chemotherapy for UCS and Type2 EAC whereas radiotherapy was the main adjuvant treatment for G3 EAC. There
were no significant differences among the groups according to overall survival (OS) (p = 0.290).
Conclusions: Although the survival difference among the groups can not be revealed, these patients have different clinical
and pathological features and they should be considered as different groups.
