All patients underwent body mass index (BMI) detection, transvaginal ultrasonography (TVUS) detection, carbohydrate antigen 125 detection, and the cervical exfoliated cell CDO1\/CELF4<\/jats:italic> gene methylation detection to analyze the sensitivity, specificity, and accuracy of different screening tests statistically with the biopsy and\/or dilation and curettage (D&C) pathological diagnosis under hysteroscopy as the gold standard.<\/jats:p>\n<\/jats:sec>\n\nResults:<\/jats:title>\nThere was no significant difference in age between the EC group and the non-EC group, P<\/jats:italic> = 0.492. Using quantitative polymerase chain reaction (qPCR) technology, we validated the CDO1<\/jats:italic> and CELF4<\/jats:italic> methylation detection with 87.5% sensitivity and 95.9% specificity as a useful strategy for the triage of women with PMB for the detection of EC. In addition, 100% of type II EC (n<\/jats:italic> = 6) were positively detected by the CDO1<\/jats:italic> or CELF4<\/jats:italic> methylation
