Is postmenopausal endometrial fluid collection alone a risk factor for endometrial cancer?

Objective: To determine the usefulness of single-layer, ultrasonographic measurement of endometrial fluid collection (EFC) volume to predict endometrial pathology in asymptomatic postmenopausal patients.

Methods: One hundred fifty asymptomatic postmenopausal women were analysed retrospectively from January 2012 to December 2016. After patients with endometrial hyperplasia/neoplasia were included in Group-I, and those with insufficient tissue, endometrial atrophy, or endometritis were included in Group-II; Groups one  and two were compared with respect to primary (correlations between endometrial thickness and EFC volume) and secondary (correlations between demographic characteristics and EFC volume) outcomes.

Results: There was no correlation between EFC volume and single-layer endometrial thickness (P = 0.36). Likewise, demographic characteristics were not related to EFC (P > 0.05). However, both EFC volume and single-layer endometrial thickness were thicker in Group-I compared to Group-II (4.8±1.9 mm vs. 3.7±2.5 mm; and 5.7±9.4 mm vs. 2.7±2.5 mm, respectively) (P values were < 0.05).

Conclusion: Although a cutoff value for endometrial thickness and EFC volume could not be recommended based on our study findings, it should be noted that 2% is a clinically significant rate of malignancy. Thus, postmenopausal patients with EFC should be evaluated for endometrial sampling.
