Criteria

Inclusion Criteria:

The patient must have consented to participate and must have signed and dated an appropriate IRB-approved consent form that conforms to federal and i institutional guidelines for the pre-entry research core biopsy for CELx HSF testing and for initiating chemotherapy
Patients must be female.
Patients must be ≥ 18 years old.
Patient must have an ECOG performance status of 0 or 1
The diagnosis of invasive adenocarcinoma of the breast must have been made by core needle biopsy.
The primary breast tumor must be palpable and measure ≥ 1.0 cm on physical exam.
The regional lymph nodes can be cN0 or cN1
The tumor size can be T1c or T2

Ipsilateral axillary lymph nodes must be evaluated by imaging (mammogram, ultrasound, and/or MRI) within 6 weeks prior to initiating chemotherapy. If suspicious or abnormal, FNA or core biopsy is recommended, also within 6 weeks prior to initiating chemotherapy. Findings of these evaluations will be used to determine the nodal status prior to initiating chemotherapy.

Nodal status - negative

Imaging of the axilla is negative;
Imaging is suspicious or abnormal but the FNA or core biopsy of the questionable node(s) on imaging is negative;

Nodal status - positive

FNA or core biopsy of the node(s) is cytologically or histologically suspicious or positive.
Imaging is suspicious or abnormal but FNA or core biopsy was not performed.
Tumor specimen obtained at the time of diagnosis must have estrogen (ER) and progesterone (PR) receptors < 10%.

Tumor specimen obtained at the time of diagnosis must have been determined to be HER2-negative as follows:

Immunohistochemistry (IHC) 0-1+; or
IHC 2+ and ISH non-amplified with a ratio of HER2 to CEP17 < 2.0, and if reported, average HER2 gene copy number < 4 signals/cells; or
ISH non-amplified with a ratio of HER2 to CEP17 < 2.0, and if reported, average HER2 gene copy number < 4 signals/cells.

Blood counts performed within 6 weeks prior to initiating chemotherapy must meet the following criteria:

Absolute neutrophil count (ANC) must be ≥ 1200/mm3;
platelet count must be ≥ 100,000/mm3; and
hemoglobin must be ≥ 10 g/dL.

The following criteria for evidence of adequate hepatic function performed within 6 weeks prior to initiating chemotherapy must be met:

total bilirubin must be ≤ upper limit of normal (ULN) for the lab unless the patient has a bilirubin elevation > ULN to 1.5 x ULN due to Gilbert's disease or similar syndrome involving slow conjugation of bilirubin; and
alkaline phosphatase must be ≤ 2.5 x ULN for the lab; and
AST must be ≤ 1.5 x ULN for the lab.
Alkaline phosphatase and AST may not both be > the ULN. For example, if the alkaline phosphatase is > the ULN but ≤ 2.5 x ULN, the AST must be ≤ the ULN. If the AST is > the ULN but ≤ 1.5 x ULN, the alkaline phosphatase must be ≤ ULN. Note: If ALT is performed instead of AST (per institution's standard practice), the ALT value must be ≤ 1.5 x ULN; if both were performed, the AST must be ≤ 1.5 x ULN.
Patients with AST or alkaline phosphatase > ULN are eligible for inclusion in the study if liver imaging (CT, MRI, PET-CT, or PET scan) performed within 6 weeks prior to initiating chemotherapy does not demonstrate metastatic disease and the requirements in criterion 4.2.13 are met.
Patients with alkaline phosphatase that is > ULN but ≤ 2.5 x ULN or unexplained bone pain are eligible for inclusion in the study if a bone scan, PET-CT scan, or PET scan performed within 6 weeks prior to initiating chemotherapy does not demonstrate metastatic disease.
Serum creatinine performed within 6 weeks prior to initiating chemotherapy must be ≤ 1.5 x ULN for the lab.
The left ventricular ejection fraction (LVEF) assessment by echocardiogram or MUGA scan performed within 90 days prior to initiating chemotherapy must be ≥ 50% regardless of the facility's lower limit of normal (LLN).
Patients with reproductive potential must agree to use an effective non-hormonal method of contraception during therapy, and for at least 7 months after the last dose of study therapy.
Patients are candidates for weekly paclitaxel and carboplatin chemotherapy as determined by treating physician.
Patients with multifocal breast cancer are included as long as none of the tumors are HER2 positive by IHC or FISH and targeted lesion meets current inclusion criteria.
Conditions for patient eligibility (Study Enrollment) A patient cannot be considered eligible for this study unless all of the following conditions are met:
The patient must have consented to participate and must have signed and dated an appropriate IRB-approved consent form that conforms to federal and institutional guidelines for the FACT-2 study treatment.
Tumor determined to have abnormal HER2-driven signaling activity based on the CELx HSF test.

Exclusion Criteria:

T3 or T4 tumors including inflammatory breast cancer.
FNA alone to diagnose the breast cancer.
Excisional biopsy or lumpectomy performed prior to initiating chemotherapy.
Surgical axillary staging procedure prior to initiating chemotherapy. Pre- neoadjuvant therapy sentinel node biopsy is not permitted. (FNA or core biopsy is acceptable.)
Definitive clinical or radiologic evidence of metastatic disease. Required imaging studies must have been performed within 6 weeks prior to initiating chemotherapy.
Synchronous bilateral invasive breast cancer. (Patients with synchronous and/or previous contralateral DCIS or LCIS are eligible.)
Any previous history of ipsilateral invasive breast cancer or ipsilateral DCIS. (Patients with synchronous or previous ipsilateral LCIS are eligible.)
Previous therapy with anthracycline, taxanes, trastuzumab, or other HER2 targeted therapies for any malignancy.
Any sex hormonal therapy, e.g., birth control pills, ovarian hormone replacement therapy, etc. (These patients are eligible if this therapy is discontinued prior to initiating chemotherapy.)
History of non-breast malignancies (except for in situ cancers treated only by local excision and basal cell and squamous cell carcinomas of the skin) within 2 years prior to initiating chemotherapy.

Cardiac disease (history of and/or active disease) that would preclude the use of the drugs included in the treatment regimens. This includes but is not confined to:

Active cardiac disease:

angina pectoris that requires the use of anti-anginal medication;
ventricular arrhythmias except for benign premature ventricular contractions;
supraventricular and nodal arrhythmias requiring a pacemaker or not controlled with medication;
conduction abnormality requiring a pacemaker;
valvular disease with documented compromise in cardiac function; and
symptomatic pericarditis.

History of cardiac disease:

myocardial infarction documented by elevated cardiac enzymes or persistent regional wall abnormalities on assessment of left ventricular (LV) function;
history of documented congestive heart failure (CHF); and
documented cardiomyopathy.
Uncontrolled hypertension defined as sustained systolic BP > 150 mmHg or diastolic BP > 90 mmHg. (Patients with initial BP elevations are eligible prior to initiating chemotherapy if initiation or adjustment of BP medication lowers pressure.)
Active hepatitis B or hepatitis C with abnormal liver function tests.
Intrinsic lung disease resulting in dyspnea.
Poorly controlled diabetes mellitus.
Active infection or chronic infection requiring chronic suppressive antibiotics.
Patients known to be HIV positive.
Nervous system disorder (paresthesia, peripheral motor neuropathy, or peripheral sensory neuropathy) ≥ grade 2, per the CTCAE v4.0.
Malabsorption syndrome, ulcerative colitis, resection of the stomach or small bowel, or other disease significantly affecting gastrointestinal function.
Other non-malignant systemic disease that would preclude treatment with any of the treatment regimens or would prevent required follow-up.
Conditions that would prohibit administration of corticosteroids.
Chronic daily treatment with corticosteroids with a dose of ≥ 10 mg/day methylprednisolone equivalent (excluding inhaled steroids).
Known hypersensitivity to any of the study drugs or any of the ingredients or excipients of these drugs (e.g., Cremophor® EL), including sensitivity to benzyl alcohol.
Pregnancy or lactation at the initiation of chemotherapy. (Note: Pregnancy testing must be performed within 2 weeks prior to initiating chemotherapy according to institutional standards for women of childbearing potential).
Psychiatric or addictive disorders or other conditions that, in the opinion of the investigator, would preclude the patient from meeting the study requirements.
Evidence after a clinical examination that the subject's tumor is progressing after treatment with one week of paclitaxel and before a CELx HSF test result is available.
