21-Gene recurrence score and locoregional recurrence in lymph node-negative, estrogen receptor-positive breast cancer

ConclusionsOur study confirms that RS is significantly associated with the risk of LRR in node-negative, ER+/HER2 − breast cancer patients. Our findings suggest that in addition to its value for prognostic stage grouping and decision-making regarding adjuvant systemic therapy, the role of the RS in identifying patients not requiring radiotherapy should be studied.
