Title: Performance of the IBIS/Tyrer-Cuzick (TC) Model by Race/Ethnicity in the Women’s Health Initiative
Presenter: Allison W. Kurian, M.D., M.Sc, Stanford University
Location: https://meetinglibrary.asco.org/record/185965/abstract

In this study, 91,893 women of differing racial identities with no personal history of breast cancer were followed for a median of 18.9 years to assess incidence of breast cancer. 6,836 new cases of breast cancer were diagnosed among the women. The Tyrer-Cuzick model was used to assess risk of breast cancer and then actual cases of breast cancer were compared to expected cases based upon the Tyrer-Cuzick risk assessment. The study found that the Tyrer-Cuzick model was an accurate predictor of breast cancer risk among various ethnicities except for Hispanic women where it overestimated breast cancer risk (ratio of observed versus expected cases overall was 0.95).

About riskScore
riskScore is a new clinically validated personalized medicine tool that enhances Myriad’s myRisk Hereditary Cancer test. riskScore helps to further predict a women’s lifetime risk of developing breast cancer using clinical risk factors and genetic-markers throughout the genome. The test incorporates data from more than 80 single nucleotide polymorphisms identified through 20 years of genome wide association studies in breast cancer and was validated in our laboratory to predict breast cancer risk in women of European descent. This data is then combined with a best-in-class family and personal history algorithm, the Tyrer-Cuzick model, to provide every patient with individualized breast cancer risk.

About Myriad myRisk Hereditary Cancer
The Myriad myRisk Hereditary Cancer test uses an extensive number of sophisticated technologies and proprietary algorithms to evaluate 35 clinically significant genes associated with eight hereditary cancer sites including: breast, colon, ovarian, endometrial, pancreatic, prostate and gastric cancers and melanoma.
