Cervical screening for women exposed in utero to<br />

diethylstilbestrol (DES)<br />

• Women exposed in utero to DES should have initial colposcopic<br />

examination. In absence of abnormality at 1 st examination, only<br />

routine cervical screening required.<br />

• Women whose initial examination showed abnormality/ stigmata<br />

DES exposure may require annual colposcopic examination<br />

vagina/ cervix, in specialist centres, possibly for life.<br />

– this should be considered on individual basis by woman concerned/<br />

colposcopist.<br />

Evidence:<br />

• Epidemiological evidence shown that women exposed to DES at<br />

increased risk clear cell carcinoma of vagina but appear not to be at<br />

high risk of developing other cancers.<br />

• Review of 4536 women exposed to DES 2x increased risk<br />

developing high-grade CIN but no increase incidence cervical<br />

cancer. Increased detection rate may due to intensive follow up.<br />
