Abstract
OBJECTIVES
We aimed to evaluate the risk of cervical and vaginal clear cell adenocarcinoma (CCA) in women, aged 50 years or more, exposed in utero to diethylstilbestrol (DES) and contribute to a reevaluation of the recommendations for cervical and vaginal cancer and pre-cancer screening for these women.
METHODS
We carried out a retrospective review for patients received in a cancer institute. Two cohorts were consecutively studied, the first from 1970 to 2003 and the second from 2004 to 2021, and then linked.
RESULTS
During the first period, we observed 61 CCA cases, with a mean age at diagnosis of 23 years (7-42), 36 (59%) following DES exposure in utero. During the second period, we found 27 cases, with one case of DES exposure (4%) for a women diagnosed at the age of 40 years. The mean age of the second cohort was 38 years (14-79). For the seven women aged 50 years or more at the time of CCA diagnosis, DES exposure was excluded for five and considered unlikely for the other two.
CONCLUSION
In total, 88 cases of cervical or vaginal CCA were observed over a period of 51 years in a cancer center. The 37 cases associated with DES exposure represented approximatively one third of the CCA related to DES expected in France. DES exposure was improbable for the seven cases of CCA for women aged 50 years or more. These results do not support the hypothesis of late cervical or vaginal CCA in women exposed to DES in utero and indicate the need for larger multicentric studies. For the present, we propose specific screening for women exposed to DES in utero in terms of : 1) methods: association of cytology and hrHPV testing, with cervical and vaginal sampling, 2) timing : annual, or without exceeding a three-year interval, continuing after 65 years of age and after hysterectomy.
