Omental Metastasis in Endometrial Carcinoma

Backgrounds: The greater omentum represents an important site of metastases in ovarian cancer and peritoneal carcinomatosis. But it is unusual in endometrial carcinoma. The current study was to determine the prevalence of omental metastasis in endometrial carcinoma and to correlate risk variable with this spread.Material and method : A retrospective analysis of patients with endometrial carcinoma who underwent omentectomy in additional to staging laparotomy was performed in the Tehran Valiasr teaching hospital from 1995 – 2015.Result: Omental metastasis were noted in 27 of the 500 patients with endometrial cancer (5.4%). Tumor histology in 17 cases (62.9%) were p serous carcinoma or clear cell carcinoma or malignant mixed mullerian tumor. 21 (77.7%) had histopathology confirmed grade 2 – 3. 16 patients (59.2%) were identified with ovarian metastasis and 13 cases (48.1%) with deep myometrial invasion. Parametrial invasion were positive in 6 patient (22.2%) and peritoneal cytology were positive in 5 (18.5%) patient. Median follow up in our study were 20 months.Conclusion: Omentectomy is one of the important surgical procedures in the high grade endometrial cancer specially serous carcinoma, clear cell carcinoma and malignant mixed mullerian tumor
