The objective of this study is to investigate the role of transvaginal ultrasound in detecting endometrial hyperplasia and endometrial cancer in women aged more than 35 presenting with abnormal uterine bleeding.

Condition Intervention

Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Role of Transvaginal Ultrasonography in Evaluating Premenopausal Women Aged More Than 35 Years With Abnormal Uterine Bleeding

Further study details as provided by Chulalongkorn University:

Primary Outcome Measures:
  • The accuracy of endometrial thickness and endometrial pattern detected by transvaginal ultrasound in predicting endometrial hyperplasia and endometrial cancer. [ Time Frame: 14 months ]

    The endometrial thickness will be measured in millimeter, at the mid-sagittal plane of the uterus, near the uterine fundus. The measurement will be performed 3 times, from basal layer of the anterior to basal layer of the posterior wall of uterine cavity. The average value of 3 measurements will be used for statistical analysis.

    The endometrial patterns are categorized into 3 groups:

    1. Triple-layer appearance
    2. Mixed echogenic pattern
    3. Hyper-echogenic pattern

Secondary Outcome Measures:
  • To identify the cut-off points of endometrial thickness that can differentiate normal endometrial pathology and endometrial hyperplasia/endometrial cancer. [ Time Frame: 14 months ]
    The results of endometrial thickness will be compared with the endometrial pathologies.The cut-off points of endometrial thickness, in millimeter, that can differentiate normal endometrial pathology and endometrial hyperplasia/endometrial cancer will be analyzed using receiver operating characteristic (ROC) curve.

Other Outcome Measures:
  • To study the prevalence of the various causes of abnormal uterine bleeding in premenopausal women aged more than 35 [ Time Frame: 14 months ]

Estimated Enrollment: 560
Study Start Date: February 2013
Estimated Study Completion Date: December 2016
Estimated Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)
