Is there an appropriate cutoff age for sampling the endometrium in premenopausal bleeding?

Area of Science:

• Reproductive Endocrinology
• Gynecologic Oncology

Background:

• Abnormal uterine bleeding (AUB) is a common gynecological complaint.
• Endometrial evaluation is crucial for identifying hyperplasia and malignancy in premenopausal women.

Purpose of the Study:

• To establish a cutoff age for endometrial sampling in premenopausal women experiencing AUB.
• To assess the relationship between age and the prevalence of endometrial hyperplasia and cancer.

Main Methods:

• Retrospective review of histopathology reports from endometrial sampling in women aged 50 or younger with AUB.
• Categorization of findings into hyperplasia without atypia, hyperplasia with atypia, and malignancy.

Main Results:

• Analysis of 2,516 patients revealed 13.5% with hyperplasia without atypia, 1% with hyperplasia with atypia, and 0.6% with malignancy.
• Logistic regression showed a significant difference in odds ratios for hyperplasia without atypia in women aged 40-50 compared to those under 40.
• No significant age-related differences were found for hyperplasia with atypia or malignancy.

Conclusions:

• A specific age cutoff for endometrial sampling to detect hyperplasia with atypia and cancer in premenopausal women with AUB cannot be determined.
• Patient management for AUB should be individualized, considering all risk factors for malignancy, irrespective of age.
