Risks of cervical intraepithelial neoplasia among DES-exposed women.
The increased occurrence of cervical intraepithelial neoplasia (CIN) in women with in utero exposure to diethylstilbestrol (DES) is described. Among 335 self-referred women exposed to DES, 14.9% (50) had a least 1 cytologic smear interpreted as CIN, and 16.2% (54) had at least 1 biopsy interpreted as CIN. Excluding those with grade 1 CIN, 8.7% (29) had at least grade 2 CIN on biopsy and 4.2% (14) had biopsies interpreted as grade 3 CIN. No invasive lesions were detected. Because the problem of differentiating true intraepithelial neoplasia from morphologically indistinguishable but benign lesions in DES-exposed women remains unresolved, the authors believe a conservative approach to treatment is still indicated. This study supports the recommendation that DES-exposed women merit continued thorough gynecologic evaluation, including regular cytologic evaluation and colposcopy, with biopsies as indicated.
