Current Primary Outcome Measures ICMJE; (submitted: March 19, 2014)	RS, as measured by Oncotype DX [ Time Frame: Up to 15 years ]; The interaction of the linear RS term and chemotherapy benefit will be tested in a Cox regression model of DFS. If the interaction is statistically significant and there is a point of equivalence between the two randomized treatments for some RS value in the range 0-25, a clinical cutpoint for recommending chemotherapy will be estimated. This estimated cutpoint is the upper bound of the 95% confidence interval on the point of equivalence. Kaplan-Meier curves comparing randomized arms generated separately for RS values below and above this cutpoint and tested with stratified log-rank tests.

Descriptive Information
Brief Title ICMJE	Tamoxifen Citrate, Letrozole, Anastrozole, or Exemestane With or Without Chemotherapy in Treating Patients With Invasive RxPONDER Breast Cancer
Official Title ICMJE	A Phase III, Randomized Clinical Trial of Standard Adjuvant Endocrine Therapy +/- Chemotherapy in Patients With 1-3 Positive Nodes, Hormone Receptor-Positive and HER2-Negative Breast Cancer With Recurrence Score (RS) of 25 or Less. RxPONDER: A Clinical Trial Rx for Positive Node, Endocrine Responsive Breast Cancer
Brief Summary	This randomized phase III clinical trial studies how well tamoxifen citrate, anastrozole, letrozole, or exemestane with or without chemotherapy work in treating patients with breast cancer that has spread from where it began in the breast to surrounding normal tissue (invasive). Estrogen can cause the growth of breast cancer cells. Hormone therapy, using tamoxifen citrate, may fight breast cancer by blocking the use of estrogen by the tumor cells. Aromatase inhibitors, such as anastrozole, letrozole, and exemestane, may fight breast cancer by lowering the amount of estrogen the body makes. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving tamoxifen citrate, anastrozole, letrozole, or exemestane is more effective with combination chemotherapy in treating patients with breast cancer.
Detailed Description	PRIMARY OBJECTIVES: I. To determine the effect of chemotherapy in patients with node positive breast cancer who do not have high recurrence scores (RS) by Oncotype DX. SECONDARY OBJECTIVES: I. To compare overall survival (OS), distant disease-free survival (DDFS) and local disease-free interval (LDFI) by receipt of chemotherapy or not and its interaction with RS. II. To compare the toxicity across the treatment arms. III. To perform other assays or tests (in particular the prediction analysis of microarray [PAM50] risk of relapse score), as they are developed and validated that measure potential benefit of chemotherapy and compare them to Oncotype DX. IV. To determine the impact of management with Oncotype DX on patient-reported anxiety (co-primary Health-Related Quality of Life [HRQL] outcome) prior to screening, after disclosure of test results, and during the randomized trial. V. To determine the impact of Oncotype DX on the initial management cost of node-positive, hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer. VI. To compare patient-reported utilities (e.g., quality of life [QOL]) for those randomized to chemotherapy versus no chemotherapy. VII. Using modeling and DFS information from the trial, to estimate the cost-effectiveness of management with Oncotype DX vs usual care. VIII. To determine the role of other assays (e.g., PAM50) as predictors of DFS, DDFS, and LDFI for patients randomized to chemotherapy versus no chemotherapy. IX. To determine the impact of treatment with chemotherapy versus no chemotherapy on patient-reported fatigue and cognitive concerns (secondary HRQL outcomes). X. To determine the impact of management with Oncotype DX on patient-reported decision conflict, perceptions regarding Oncotype DX testing, and survivor concerns prior to screening, after disclosure of test results, and during the randomized trial (secondary HRQL outcomes). OUTLINE: Patients are randomized to 1 of 2 treatment arms. ARM I: Patients receive a protocol-approved chemotherapy regimen based on the patient and/or physician preference. Patients then receive a protocol-approved adjuvant endocrine therapy comprising tamoxifen citrate, an aromatase inhibitor (anastrozole, letrozole, or exemestane), or both for 5-10 years in the absence of disease progression or unacceptable toxicity. ARM II: Patients receive a protocol-approved endocrine therapy comprising tamoxifen citrate, an aromatase inhibitor (anastrozole, letrozole, or exemestane), or both for 5-10 years in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for 1 year, every 6 months for 4 years, and then yearly for 15 years.

Patients must not be pregnant or nursing; women of reproductive potential must have agreed to use an effective contraceptive method; a woman is considered to be of "reproductive potential" if she has had menses at any time in the preceding 12 consecutive months; in addition to routine contraceptive methods, "effective contraception" also includes heterosexual celibacy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) defined as a hysterectomy, bilateral oophorectomy or bilateral tubal ligation; however, if at any point a previously celibate patient chooses to become heterosexually active during the time period for use of contraceptive measures outlined in the protocol, he/she is responsible for beginning contraceptive measures; No other prior malignancy is allowed except for adequately treated basal cell (or squamous cell) skin cancer, in situ cervical cancer, or other cancer for which the patient has been disease-free for 5 years;
