21-Gene Recurrence Score Assay As a Predictor of Adjuvant Chemotherapy Administration for Early-Stage Breast Cancer: An Analysis of Use, Therapeutic Implications, and Disparity Profile [Breast Cancer]

Conclusion The RS assay significantly influences clinicians’ recommendations for chemotherapy in patients with EBC. Black patients tended to have higher assay scores, which may reflect use patterns or less favorable tumor biology for estrogen receptor–positive disease. There are significant differences in use and clinical implications of the test on the basis of race, insurance, and type of facility.
