OBG · Gynaecological oncology: endometrial hyperplasia
Sample itemWhich type of endometrial hyperplasia has the highest risk of progression to carcinoma?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. Atypical hyperplasia (endometrial intraepithelial neoplasia)
Atypical hyperplasia progresses to cancer in about 25 to 30 per cent, and coexisting cancer is found in up to 40 per cent at hysterectomy. Hysterectomy is advised in women who have completed childbearing. LNG-IUS is an option for fertility-sparing treatment.
Option by option
A. Proliferative endometrium
Proliferative endometrium is normal.
B. Complex hyperplasia without atypia
Complex hyperplasia without atypia has about 3 per cent progression.
C. Simple hyperplasia without atypia
Simple hyperplasia has about 1 per cent progression.
D. Atypical hyperplasia (endometrial intraepithelial neoplasia) (correct)
Correct. Cytological atypia raises the risk markedly.
