Abstract excerpt

BACKGROUND: In women with early stage, hormone receptor (HR)-positive (HR(+)) breast cancer, the 21-gene recurrence score (RS) assay quantifies recurrence risk and predicts chemotherapy responsiveness. Recent data suggest that not all women with early-stage, HR(+) disease receive this testing. We examined sociodemographic, clinical, and attitudinal factors associated with RS testing receipt and the RS testing...
