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.
Further Study Information
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.
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 have a histologically confirmed diagnosis of node positive (1-3 nodes) invasive breast carcinoma with positive estrogen and/or progesterone receptor status, and negative HER-2 status; estrogen and progesterone receptor positivity must be assessed according to American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) guidelines as either estrogen receptor (ER) or progesterone receptor (PR) >= 1% positive nuclear staining; HER-2 test result negativity must be assessed as per ASCO/CAP 2013 guidelines using immunohistochemistry (IHC), in situ hybridization (ISH) or both; HER-2 is negative if a single test (or all tests) performed in a tumor specimen show: a) IHC negative (0 or 1+) or b) ISH negative using single probe or dual probe (average HER-2 copy number < 4.0 signals per cell by single probe or HER-2/CEP ration < 2.0 with an average copy number < 4.0 signals per cell by dual probe); if HER-2 IHC is 2+, evaluation for gene amplification (ISH) must be performed and the ISH must be negative; ISH is not required if IHC is 0 or 1+; HER-2 equivocal is not eligible
Patients with multifocal, multicentric and synchronous bilateral breast cancers are allowed
Multifocal disease is defined as more than one invasive cancer < 2 cm from the largest lesion within the same breast quadrant; (NOTE: the Oncotype DX testing must be completed on the largest lesion)
Multicentric disease is defined as more than one invasive cancer >= 2 cm from the largest lesion within the same breast quadrant or more than one lesion in different quadrants (NOTE: Oncotype DX testing should be completed on all tumors and the determination for eligibility should be made on the highest recurrence score)
Synchronous bilateral disease is defined as invasive breast cancer with positive lymph nodes (axillary or intramammary) in at least one breast, diagnosed within 30 days of each other; (NOTE: the Oncotype DX testing should be completed on both tumors and the tumor with the highest recurrence score should be used)
Patients will have undergone axillary staging by sentinel node biopsy or axillary lymph nodes dissection (ALND); patients must have at least one, but no more than three known positive lymph nodes (pN1a, pN1b or pN1c); patients with micrometastases as the only nodal involvement (pN1mi) are not eligible; patients with positive sentinel node are not required to undergo full axillary lymph node dissection; this is at the discretion of the treating physician; axillary node evaluation is to be performed per the standard of care at each institution
Patients must not have inflammatory breast cancer and must not have metastatic disease
Patients with a prior diagnosis of contralateral ductal carcinoma in situ (DCIS) are eligible if they underwent a mastectomy or lumpectomy with whole breast radiation; prior partial breast irradiation, including brachytherapy, is not allowed; patients with a prior diagnosis of ipsilateral DCIS or invasive breast cancer who received radiation to that breast are not eligible
Patients must have had either breast-conserving surgery with planned radiation therapy or total mastectomy (with or without planned postmastectomy radiation); patients must have clear margins from both invasive breast cancer and DCIS (as per local institutional guidelines); lobular carcinoma in situ (LCIS) at the margins is allowed
Registration of patients who have not yet undergone Oncotype DX screening must occur no later than 56 days after definitive surgery; (for all patients, Step 2 Registration must occur within 84 days after definitive surgery); if the Oncotype DX Breast Cancer Assay has not been performed, patients must be willing to submit tissue samples for testing to determine the Recurrence Score value; a representative block or unstained sections from the representative block are sent directly to Genomic Health for Oncotype DX Breast Cancer Assay which will be performed according to the standard commercial process
If the Oncotype DX Recurrence Score is already known and is 25 or less, the patient must be registered to Step 2 immediately following Step 1 registration; if the Oncotype DX Recurrence Score is already known and is greater than 25, the patient is ineligible
Patients must have a complete history and physical examination within 28 days prior to registration
Patients must have a performance status of 0-2 by Zubrod criteria
Patients must be able to receive taxane and/or anthracycline based chemotherapy
Patients must not have begun chemotherapy or endocrine therapy for their breast cancer prior to registration
Patients must not require chronic treatment with systemic steroids (inhaled steroids are allowed) or other immunosuppressive agents
Patients must not have received an aromatase inhibitor (AI) or a selective estrogen receptor modulator (SERM) such as tamoxifen or raloxifene within 5 years prior to registration
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
The Quality of Life and Economic Substudy is permanently closed to accrual effective 12/1/12; patients who consented to QOL prior to 12/1/12 should continue to complete QOL forms per their expectation report; patients who are able to complete a questionnaire in English must be offered the opportunity to participate in the Quality of Life and Economic Substudy; (The Quality of Life and Economic Substudy is available to U.S. INSTITUTIONS ONLY); patients who are not able to complete a questionnaire in English are registered to S1007 without participating in the Quality of Life and Economic Substudy
Patients who consent to participate in the Quality of Life and Economic Substudy and who do not yet know the results of their Oncotype DX screening must agree to complete the S1007 Health-Related Quality of Life Questionnaire: Enrollment between 14 days prior to and 7 days after Step 1 Registration
Patients who consent to participate in the Quality of Life and Economic Substudy and who do already know their Oncotype DX Recurrence Score (and it is 25 or less) will proceed to Step 2 Registration without completing the S1007 Health-Related Quality of Life Questionnaire Enrollment Form (but will complete the S1007 Health-Related Quality of Life Questionnaire: Randomized Study Form)
Patients or their legally authorized representative must be informed of the investigational nature of this study and must sign and give written informed consent in accordance with institutional and federal guidelines; for Step 1 registration of patients who have not yet submitted specimens for the Oncotype DX Breast Cancer Assay, the appropriate consent form is the Step 1 Consent Form; for both Step 1 and Step 2 registration of patients whose Recurrence Score is already known and is 25 or less, the appropriate consent form is the Step 2 Consent Form
As a part of the Oncology Patient Enrollment Network (OPEN) registration process the treating institution's identity is provided in order to ensure that the current (within 365 days) date of institutional review board approval for this study has been entered in the system
STEP 2 REGISTRATION
Recurrence score (RS) by Oncotype DX must be =< 25
Step 2 Registration must take place within 84 days after definitive surgery; patients must not have begun chemotherapy or endocrine therapy for their breast cancer prior to randomization
Patients randomized to either arm may also co-enroll in phase III trials that compare local therapies, or compare systemic therapies (such as chemotherapy, if randomized to Arm I of S1007)
The Quality of Life and Economic Substudy is permanently closed to accrual effective 12/1/12; patients at U.S. INSTITUTIONS who consent to participate in the Quality of Life and Economic Substudy must agree to complete the S1007 Health-Related Quality of Life Questionnaire: Randomized Study Form after Recurrence Score results and randomized treatment status are known but before treatment has been initiated
Patients or their legally authorized representative must be informed of the investigational nature of this study and must sign and give written informed consent in accordance with institutional and federal guidelines; for all patients the appropriate consent form for this registration is the Step 2 Consent
