Resolution of endometrial hyperplasia with adjuvant anastrozole treatment in postmenopausal breast cancer: a case report.

BACKGROUND

Endometrial hyperplasia in patients with a history of breast cancer presents a therapeutic dilemma. The standard conservative therapy for hyperplasia, high-dose progestins, is contraindicated in breast cancer. Anastrozole, an aromatase inhibitor, is becoming first-line adjuvant therapy for breast cancer in postmenopausal women and may have protective effects on the endometrium.

CASE: A 51-year-old, obese woman with a history of breast cancer presented with a 2-day history of heavy postmenopausal bleeding. Endometrial biopsy demonstrated simple hyperplasia without cellular atypia. After consultation with the patient's oncologist, the patient received adjuvant anastrozole therapy for the breast cancer; it led to resolution of the endometrial hyperplasia.

CONCLUSION

Adjuvant therapy with anastrozole may be beneficial in resolving endometrial hyperplasia in patients with breast cancer.
