Significance of atypical endometrial cells detected by cervical cytology.
A retrospective study was conducted to assess the histologic significance of atypical endometrial cells identified on routine cervical cytology. One hundred seventy-seven women had Papanicolaou smears demonstrating atypical endometrial cells. The histology of the endometrium was available from endometrial sampling and/or hysterectomy in 134 of the patients within 12 months of their abnormal cytologic evaluation. Fifty-six women (42%) had endometrial disease, including 14 cases (10%) of endometrial polyp, 15 cases (11%) of endometrial hyperplasia, and 27 cases (20%) of adenocarcinoma. The frequency and nature of the endometrial changes depended on the age of the patient (P less than .001) and the degree of cytologic atypia (P less than .05). In 21 women over 59 years who had atypical endometrial cells suspicious for adenocarcinoma, 12 (57%) had adenocarcinoma. Using this information, we have estimated the risk of adenocarcinoma in various groups of women with atypical endometrial cells.
