Kaban A, et al. – Here, researchers want to know whether omentectomy ought to be part of a staging procedure in patients with non–endometrioid endometrium cancers (non–ECC). In addition to, the sensitivity and specificity of the visual assessment of omentum were investigated. Omental metastases occur too often to omit omentectomy amid surgical procedures for non–ECC regardless of histological subtypes, and the visual evaluation is inadequate in recognizing the often occult metastases. In patients with non–ECC, omentectomy ought to be a part of the staging surgery.

Methods

• Between 2005 and 2015, patients diagnosed with non–ECC in 2 gynecological oncology clinics were retrospectively reviewed.
• In this study, occult (absence of visible lesions) and gross (presence of visible lesions) omental metastasis rates of histological subtypes were examined.

Results

• Total 218 patients with non–ECC were identified.
• In this study, 34 of them (15.1%) had omental metastases and 44.1% of these metastases (n = 15) were occult metastases.
• The sensitivity of the surgeon's visual evaluation of an omentum (positive or negative) was 0.55.
• The highest rate of omental metastasis was found in carcinosarcoma followed by serous, mixed subtypes, and clear–cell (20.4, 17.3, 16.6, 10.0%, respectively).
• Adnexal metastasis was the only factor related to occult omental metastasis (p = 0.003).
