Metindir J et al. - In a study to evaluate whether omentectomy should be a routine part of staging surgery in endometrioid adenocarcinoma, it was shown that despite the presence of normal-appearing omentum, omentectomy should be performed as a component of surgical staging in the presence of positive peritoneal cytology Methods
A retrospective study was performed on 65 pts who were primarily treated by total abdominal hysterectomy, salpingo-oophorectomy, bilateral pelvic and para-aortic lymphadenectomy, infracolic omentectomy and peritoneal cytology for clinical stage I endometrial carcinoma
Data on 65 pts diagnosed with clinical stage I endometrial carcinoma were reviewed
Associations in the data obtained, pelvic and para-aortic lymph node status, depth of myometrial invasion, grade, vascular invasion, adnexal involvement, positive peritoneal cytology, lymph node metastasis, cervical stromal invasion, and tumor size, were investigated
Results
4 of 65 pts had omental metastasis, which was microscopic in 2 pts
As for extrauterine spread, the positivity rate of lymph node metastases was 10/65, peritoneal cytology was 7/65, and adnexal metastases was 10/65
Of those with omental metastasis, 2/10 had positive nodes, 2/10 had adnexal metastases, and 3/7 had positive peritoneal cytologic findings
The 4 pts with omental metastasis had significantly higher rates of positive cytology
Multivariate analysis revealed omental metastasis to be significantly associated with positive peritoneal cytology
