Study Summary

Primary Objectives: 1. To prospectively evaluate the predictive accuracy of a previously discovered gene expression profile-based test to foretell pathologic complete response (pCR) to preoperative paclitaxel/FAC (5-fluorouracil, doxorubicin, cyclophosphamide) chemotherapy for stage I-III breast cancer. 2. To evaluate if our genomic predictive test is specific to the paclitaxel/FAC regimen or it also predicts increased sensitivity to FAC only chemotherapy. Secondary Objectives: 1. To discover a molecular profile that is associated with pCR after FAC chemotherapy alone 2. To establish a prospectively collected gene expression profile data bank of breast cancer for future studies 3. To compare the pCR rates between patients who receive 6 courses FAC and those who receive sequential paclitaxel /FAC chemotherapies.

Primary Outcome

Pathologic Complete Response Rate after completion of preoperative chemotherapy, based on routine clinical pathology report where Pathologic complete response defined as complete absence of any viable invasive cancer cells in resected breast and lymph nodes. Specimens in breast may contain in situ cancer (ductal or lobular carcinoma in situ) and still be considered complete response.
