- pCR, determined from the surgical specimen and is defined as the absence of invasive carcinoma in both the breast and axilla at microscopic examination of the resection specimen, regardless of the presence of carcinoma in situ [ Time Frame: 12 weeks ]The pCR rates and exact one-sided 80% confidence intervals will be calculated. The primary analysis is based on the full analysis set (all treated patients). The pCR rates will be summarized overall and for HER+ and HER- subsets.
- Overall incidence and severity of toxicities, graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 [ Time Frame: Up to 30 days after completion of study treatment ]Adverse events will be tallied for overall frequency (number and percentage of subjects), worst reported severity, and relationship to study drugs. Serious adverse events will be summarized similarly. Listings of deaths, serious adverse events (SAEs) and adverse events (AEs) leading to early termination of study treatment or premature withdrawal from study will also be provided. Analyses will be reported overall and for HER+ and HER- subsets.
- Clinical complete response [ Time Frame: Up to 2 years ]
- Failure-free survival (FFS) [ Time Frame: The time from the date of administration of study drug to the date of first appearance of tumor lesions by imaging, or death, assessed up to 2 years ]The analysis will be based on Kaplan-Meier estimates. FFS will be summarized overall and for HER+ and HER- subsets.
- Overall survival (OAS) [ Time Frame: The time from the date of the date of administration of study drug to the date of death from any cause, assessed up to 2 years ]The analysis will be based on Kaplan-Meier estimates. OAS will be summarized overall and for HER+ and HER- subsets.
- Identification of gene expression profile signatures that correlate with clinical response as measured by pCR [ Time Frame: Up to 2 years ]The number of the identified mutated genes, the frequency of each gene being validated by reverse transcriptase-polymerase chain reaction (RT-PCR)/Sanger sequencing method, and the functions of these identified genes will be descriptively summarized.

I. To evaluate the toxicities and tolerability of a neoadjuvant dose-dense regimen cyclophosphamide and paclitaxel with or without trastuzumab/radiation therapy (as clinically indicated) in patients with newly diagnosed stage T1cN0 and II-III breast cancer; followed by maintenance trastuzumab in human epidermal growth factor receptor 2 (HER2) positive OR Adriamycin (doxorubicin hydrochloride) followed by radiation therapy (RT) in stage II-III triple negative HER2 (-), estrogen receptor (ER) (-), progesterone receptor (PR) (-) stage T1cN0 and II-III breast cancer patients.
II. To determine the pathological complete response rate (pCR) of this treatment regimen.
III. To identify possible gene expression profile signatures from whole genome array analysis that correlate with clinical response/resistance to chemotherapy as measured by pathologic complete response rate (pCR).
NEOADJUVANT THERAPY: Patients receive paclitaxel intravenously (IV) over 3 hours and cyclophosphamide IV over 1 hour on day 1. Patients with HER2-positive cancer also receive trastuzumab IV over 30 minutes on day 1. Treatment repeats every 14 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients without metastasis undergo mastectomy or breast conserving surgery 4-8 weeks later.
HER2-POSITIVE PATIENTS: Patients receive standard radiation therapy. Patients also receive trastuzumab IV over 30 minutes on day 1. Treatment repeats every 21 days for up to 13 courses in the absence of disease progression or unacceptable toxicity.
ER/PR POSITIVE PATIENTS: Patients receive standard adjuvant hormonal or endocrine therapy.
STAGE T1cN0 TRIPLE NEGATIVE PATIENTS: Patients receive standard radiation therapy.
STAGE II-III TRIPLE NEGATIVE PATIENTS: Patients receive doxorubicin hydrochloride IV over 15 minutes on day 1. Treatment repeats every 14 days for up to 4 courses in the absence of disease progression or unacceptable toxicity. Patients also receive standard radiation therapy.
After completion of study treatment, patients are followed up every 3 months for 2 years.
