Abstract excerpt

IMPORTANCE: Guidelines recommend consideration of chemotherapy for most patients with early-stage, estrogen receptor-positive, invasive breast cancer in the absence of additional prognostic information. The 21-gene recurrence score (RS) assay has been shown in limited academic settings to reduce physician recommendations for adjuvant chemotherapy. Associations between the adoption of the assay and receipt of...
