1. Documentation of Disease:
1.1 Subjects must have histologically confirmed invasive breast cancer and
registration must occur within 14 months after the first histologic diagnosis of
invasive breast cancer.
- A core biopsy interpreted as invasive cancer meets this criterion; if no core
biopsy is performed, the date of first histologic diagnosis will be the date of
first surgical procedure that identifies invasive cancer (biopsy, lumpectomy or
mastectomy).
- Neoadjuvant subjects should have no evidence of clinical T4 disease prior to
chemotherapy and surgery; eligibility for neoadjuvant patients can be defined
by either clinical stage prior to therapy or pathologic stage at surgery; if
patient is eligible based on either, they are eligible for the study.
- Bilateral breast carcinoma is allowed provided diagnoses are synchronous - that
is, within 3 months of one another - and at least one of the two breast
carcinomas meet the eligibility criteria and neither Her-2 positive or
inflammatory.
- No evidence of metastatic disease
1.2 Her-2 negative, defined as:
- In-situ hybridization (ISH) ratio of < 2.0 (if performed)
- Immunohistochemistry (IHC) staining of 0-2+ (if performed)
- Deemed to not be a candidate for Her-2 directed therapy.
1.3 Eligible tumor-node-metastasis (TNM) Stages include:
- Estrogen receptor (ER) and Progesterone receptor (PR) negative (defined as <1%
staining for ER and PR by IHC): T2 or T3 N0, T0-3N1-3. Note: Patients with T1,
N1mi disease are NOT eligible.
- ER and/or PR positive (defined as ≥ 1% staining for ER and/or PR on IHC):
T0-3N1-3 or T3N0. Note: Patients with T0N0, T1N0, T2N0 or T1N1mi and T2N1mi
disease are NOT eligible.
- The eligibility of neo-adjuvant subjects can be assessed on the basis of
clinical (c)TNM or pathologic (yp)TNM. The same eligible TNM combinations
apply; patients may be eligible if they meet eligibility requirements at either
time point, as long as they do not have T4 disease prior to therapy.
1.4 No history of invasive breast cancer in 5 years prior to study registration
other than the current diagnosis (prior ductal breast carcinoma in situ [DCIS] at
any time is acceptable).
1.5 Patients must have had a bilateral mammogram within 12 months prior to
registration, unless the initial surgery was a total mastectomy, in which case only
a mammogram of the remaining breast is required. (Subjects with bilateral total
mastectomies do not require imaging).
1.6 Investigations, including chest X-ray or computed tomography (CT) chest, bone
scan (with radiographs of suspicious areas) and abdominal ultrasound or liver scan
or CT abdomen have been performed between the first histologic diagnosis and the
time of registration as detailed below.
- Chest X-Ray, 2 view (or Chest CT, or positron emission tomography [PET]/CT) is
mandatory
- Bone scans (with x-rays of abnormal areas) are required only if alanine
aminotransferase (ALT), aspartate aminotransferase (AST) or Alkaline
Phosphatase is elevated or if there are signs or symptoms of metastatic disease
- Abdominal imaging is required only if ALT, AST or Alkaline Phosphatase is
elevated or if there are signs or symptoms of metastatic disease
2. Prior Treatment
2.1 All adjuvant or neoadjuvant chemotherapy, radiation, and surgery completed at
least 21 days prior to registration.
2.2 All triple negative patients must receive chemotherapy of the treating
physician's choice.
2.3 ER/PR+ patients must receive chemotherapy (of the treating physician's choice)
unless Oncotype Dx or another genomic predictor score indicates that they are at low
or intermediate risk of disease recurrence with endocrine therapy alone.
2.4 Patients may have breast reconstruction during protocol participation, but
definitive breast cancer surgery must be completed at least 21 days prior to
registration.
Concomitant biologic therapy, hormonal therapy, and bisphosphonates are acceptable.
2.5 Surgical margins must be clear of invasive carcinoma. If there is microscopic
residual ductal in situ disease present at lumpectomy or total mastectomy margins,
further excision is highly recommended. If further excision is not undertaken, the
subject may still be entered on study, provided that in addition to breast or chest
wall irradiation, a boost to the tumor bed is delivered. In situ lobular disease at
the margin is acceptable.
2.6 All subjects (both adjuvant and neoadjuvant) must have sentinel lymph node
biopsy and/or axillary lymph node dissection. Sentinel lymph node biopsy alone is
allowed in the following instances:
- Sentinel lymph node biopsy is negative: pN0
- Sentinel lymph node biopsy is positive for isolated tumor cells only:
pN0 (i+)
- Clinically node negative, T1-2 tumors with sentinel lymph node biopsy positive
in < 2 lymph nodes without matted nodes and undergoing breast conserving
surgery and tangential whole breast irradiation, or undergoing mastectomy and
chest wall irradiation.
- For patients who had a positive node prior to neoadjuvant chemotherapy,
sentinel node alone is allowed after neoadjuvant therapy if:
- Sentinel node biopsy is negative after chemotherapy and either at least 2
sentinel nodes were removed or a clip was placed in the involved node
prior to treatment.
- =< 2 lymph nodes are positive for cancer and the patient is participating
in A011202
- All women who undergo breast conserving therapy must receive concomitant
radiotherapy. Radiation after mastectomy is to be administered according to
prespecified institutional guidelines. Radiation must be completed at least 21
days prior to registration.
- Patients with hormone receptor positive breast cancer as defined above must
receive at least 5 years of adjuvant hormonal therapy in the form of tamoxifen
or an aromatase inhibitor, alone or in combination with ovarian suppression.
(NOTE: for patients with ER and PR staining in less than 5% of cells, hormonal
therapy for at least 5 years is strongly recommended but not required).
Hormonal therapy can be initiated prior to or during protocol therapy.
3. Participants must be women
4. Age ≥ 18 years
5. Eastern Cooperative Oncology Group (ECOG) Performance Status 0 or 1
6. Comorbid Conditions
6.1 No history of other malignancy within the past 4 years, except for malignancies
with a >95% likelihood of cure (e.g. non-melanoma skin cancer, papillary thyroid
cancer, in situ cervical cancer). Patients cannot have metastatic breast or other
cancer.
6.2 No diabetes mellitus currently treated with insulin or sulfonylureas.
6.3 No history of serious digestive and/or absorptive problems, including
inflammatory bowel disease and chronic diarrhea that preclude adherence to the study
diet.
6.4 No history of severe cardiovascular, respiratory or musculoskeletal disease or
joint problems that preclude moderate physical activity. Examples would include
unstable angina, recent myocardial infarction, oxygen-dependent pulmonary disease,
and osteoarthritis requiring imminent joint replacement. Moderate arthritis that
does not preclude physical activity is not a reason for ineligibility.
6.5 No prior bariatric surgery or planning to undergo this procedure within the next
2 years after study registration.
6.6 No comorbid conditions that would cause life expectancy of less than 5 years.
6.7 No history of psychiatric disorders that would preclude participation in the
study intervention (e.g. untreated major depression or psychosis, substance abuse,
severe personality disorder) or prevent the patient from giving informed consent.
7. Other
7.1 BMI ≥27 kg/m2 documented within 56 days prior to study registration. The most recent
BMI obtained must be used for eligibility. If most recent BMI is <27 then the patient is
not eligible to enroll.
7.2 Self-reported ability to walk at least 2 blocks (at any pace).
7.3 Not participating in another weight loss, physical activity or dietary intervention
clinical trial. Co-enrollment in some trials involving pharmacologic therapy is allowed.
Participants in both arms are also allowed to pursue weight loss and physical activity
programs on their own, as long as these programs are not provided as part of a clinical
trial.
7.4 Able to read and comprehend English. Eligibility is restricted to individuals who can
comprehend and read English given that participation in the study will require the
ability to read lifestyle intervention materials and communicate with a coach through 42
phone calls over 2 years. The study team plans to make the intervention available in
Spanish in the future.
