The value of additional pathology comments indicating suspicion of adenocarcinoma among women diagnosed preoperatively with complex atypical endometrial hyperplasia

Over 40% of women with a preoperative diagnosis of complex atypical hyperplasia (CAH) will have endometrial cancer at hysterectomy. CAH diagnoses are often qualified by comments indicating suspicion of cancer. We examine whether these comments correlate with cancer found at hysterectomy. Pathology reports for 824 women with CAH diagnoses who underwent hysterectomy were reviewed to identify those qualified by comments indicating concern for cancer. The rate of cancer, severity of disease, and effects of endometrial sampling method and age were determined. Comments indicating suspicion of cancer qualified 219 of 824 (27%) CAH diagnoses and were associated with a significantly higher cancer rate at hysterectomy (69% versus 40%; P<0.0001), regardless of whether sampling consisted of curettage or biopsy. Cancer severity correlated independently with age. Comments indicating concern for underlying cancer frequently qualify CAH diagnoses and are associated with a high likelihood of cancer and with more extensive disease, especially for older women.
