Abstract excerpt

IMPORTANCE: In 2006, the Centers for Medicare & Medicaid Services approved coverage for the use of the 21-gene recurrence score (RS) assay in women with early-stage, estrogen receptor-positive, node-negative breast cancers to help guide recommendations for adjuvant chemotherapy. Use of the assay in community settings has not been previously examined in a nationally representative sample of patients. OBJECTIVE: To...
