Abstract

We assessed reliability of self-reported diagnostic radiation history in BRCA1/2 mutation carriers with and without breast cancer. Within the frame-work of the HEBON study, 401 BRCA1/2 mutation carriers completed a baseline (1999-2004) and a follow-up questionnaire (2006-2007). Test-retest reliability of self-reported exposure to chest X-rays, fluoroscopies and mammograms was assessed for the entire study population and by case status.Overall proportion agreement on reporting ever/never exposure was good ([75%), while the corresponding kappa coefficients were between 0.40 and 0.75, indicating at least moderate reliability beyond chance. Reliability of number of exposures was also good ([75%). Proportion agreement on reporting age at first mammogram was low(40%) for exact consistency and moderate (60%) for consistency +/- 1 year. Reliability of age at first mammogram was higher for cases than for unaffected carriers(P
