If the 5-year risk of breast cancer by the Gail model
is greater than 1.
This compares favorably to the National Cancer Institute Gail Model
for Breast Cancer (a concordance index of 0.
66, determined by the Gail model
, were classified as high-risk for breast cancer.
It equates on the Gail model
to being 65 years old without additional risk factors.
While this model is well calibrated, it is not very discriminatory; for a large group of women, the Gail model
will successfully predict the expected number of breast cancers but it is not good at predicting which women will develop breast cancer (18).
5, which aligns it with other indicators of risk assessment in the Gail model
For the same women, they used the existing Gail model
to make five-year risk predictions for the same women.
The Gail model
evaluates breast cancer risk based on criteria including age and family history, with 1.
The modified Gail model
is the most widely used risk assessment model.
The Gail Model
Risk Assessment Tools will be available from Cytogen to aid in accessing risk.
Data were compared for all participants and across a variety of subgroups, including age (younger or older than 50 years), breast density (heterogeneously dense, extremely dense, or less dense), menopausal status (pre-, peri-, or postmenopausal), race (white, black, or other), and lifetime risk of breast cancer (>25% or <25%), as determined by the Gail model
The Gail model
does not, however, recognize certain risk factors that may influence the degree of risk in some women.
