According to updated results from the phase 3 randomized RxPONDER study, postmenopausal women with hormone receptor (HR)–positive, human epidermal growth factor receptor 2 (HER2)–negative breast cancer with one to three positive nodes and a 21-gene RS ≤ 25 (Oncotype DX) derive no further benefit from chemotherapy compared with endocrine therapy only. Conversely, premenopausal patients with the same clinical characteristics derive a ~5% absolute recurrence risk reduction from the addition of chemotherapy to endocrine therapy. However, whether the benefit is driven by chemotherapy itself or is mostly driven by chemotherapy-induced amenorrhea is debated.

Evidence suggests that chemotherapy does offer survival benefits for patients aged 70 years or older with TNBC. A recent study found that older women with TNBC who received chemotherapy had significantly improved survival compared with those who were recommended to undergo chemotherapy but did not receive it.
