Abstract

Abstract : In the Diethylstilbestrol [DES] Combined Cohort Follow‐up, the age‐ and calendar‐year specific standardized incidence ratio [SIR] for clear cell adenocarcinoma [CCA] was 27.6 (95% confidence interval [CI] 7.51‐70.6) for the exposed women. The SIR for breast cancer was 1.17 (95% CI 1.01‐1.36) and the hazard ratio [HR] adjusted for birth year and cohort for comparison with the unexposed was 1.05 (95% CI 0.79‐1.41). The SIR for pancreatic cancer was 2.43 (95% CI 1.21‐4.34) and the adjusted HR for comparison with unexposed women was 7.16 (95% CI 0.84‐61.5). There was little evidence of excess risk for other sites. There appeared to be a deficit in risk for endometrial cancer among the exposed (SIR 0.61; 95% CI 0.35‐0.98), and an excess in the unexposed (SIR 1.55; 95% CI 0.95‐2.40); the adjusted HR was 0.45 (95% CI 0.22‐0.93) for the internal comparison. There was no overall excess cancer risk in exposed women compared with general population rates (1.06; 95% CI 0.95‐1.17) or with unexposed participants (adjusted HR 1.03; 95% CI 0.84‐1.25). These data do not support the suggestion that there is a diathesis of cancers in DES exposed female offspring The excess risk of breast and pancreatic cancers that we observed is concerning and warrants continued follow‐up and mechanistic investigation.
