Title	S1007 - " A Phase III, Randomized Clinical Trial of Standard Adjuvant Endocrine Therapy +/- Chemotherapy in Patients iwth 1-3 Postiive Nodes, Hormone Receptor-Positive and HER2-Negative Breast Cancer With Recurrence Score of 25 or less"
Description	Primary Objective: To determine the effect of chemotherapy in paitients with node positive breast cancer who do no have high Recurrence Scores (RS) by Oncotyp eDX. In patients with 1-3 positive nodes, and hormone receptor (HR) -positive, HER2-negative breast cancer with RS<25 treated with endocrine therapy we will test whether the difference in disease-free survival for patients treated with chemotherapy compared to no chemotherapy depends directly on the magnitude of RS. If benefit depends on the RS score, the trial will determine the optimal cutpoint for reommending chemotherapy or not.
Treatment	Oncology
Inclusion/Notes	ELIGIBILITY: - Patient must have a histologically confirmed diagnosis of node positive (1-3nodes) invasive breast carcinoma iwth positive ER and/or PR status. ER and PR positivity must be assessed according to ASCO/CAP guidelines.
