About the study:
In 1971, the development of clear cell adenocarcinoma of the vagina and cervix in young women were linked to in-utero exposure to Diethylstilbestrol (DES). In 1974, The National Cancer Institute issued a request for proposal to study the problem of cancer detection and prevention in DES-exposed offspring through identification and examination of DES-exposed men and women. Approximately 1435 participants were enrolled into the Baylor DESAD Study.
Prenatal records of physicians and clinics willing to participate in the project were reviewed for identification of pregnancies in which DES was prescribed. These records were linked to delivery data to accomplish identification of live births. Subsets of both exposed and unexposed daughter were “matched”. Participants were also enrolled from women seeking “DES examinations” (walk-in) or from referrals by physician, only if prenatal records documenting exposure to DES were available. Prenatal records from the same sources that indicated no exposure to hormonal medications became the basis for identification of “control” subjects. In 2010, funding was once again awarded in order to obtain current health information from the daughters who participate in the DES Follow-up Study. Sons are not followed at this center.
