Research published in Cancer indicated that conventional mammography screening performance metrics underestimate the interval cancer rate of a mammography screening episode, especially in women with dense breasts or an elevated risk of breast cancer.
Given these findings, the investigators suggested that women, clinicians, policymakers, and researchers consider screening outcome measures based on the final assessment to support informed decisions about routine screening and the need for supplemental breast cancer screening.
“These differences have consequences for women, health care providers, and policymakers considering primary and supplemental breast cancer screening strategies,” the authors wrote.
Using data from 2,512,577 screening episodes among 791,347 individual women taken from 2005 to 2017 across 146 facilities in the US participating in the Breast Cancer Surveillance Consortium, researchers compared screening performance metrics based on the final assessment of screening episode with conventional metrics defined with the initial assessment.
