Objectives: To determine the incidence of endometrial cancer in patients undergoing hysterectomy for atypical complex endometrial hyperplasia and to study the risk of advanced endometrial cancer that may be associated with extra-uterine disease.
Methods: A retrospective chart review was performed of the records of all women who underwent hysterectomy for a preoperative diagnosis of complex hyperplasia with atypia from two teaching hospitals between 1999 and 2006. Demographic and clinical variables were collected and analyzed for the 80 patients identified by the initial screening methods.
Results: After screening and exclusions, 66 women with a preoperative diagnosis of atypical complex hyperplasia who subsequently underwent a hysterectomy were identified. Eleven of the 66 patients with atypical complex hyperplasia had a diagnosis of endometrial carcinoma in the hysterectomy specimens (17%). No endometrial cancer patient was staged greater than stage 1B or had greater than grade 2 disease. The patients with endometrial cancer were older (p < 0.05). Evidence of myometrial invasion was found in 63% (7/11) of the cancer cases, but all were less than 50% of the myometrium.
Conclusion: Endometrial cancer found at the time of hysterectomy for complex hyperplasia with atypia may be associated with less advanced disease.
