The purpose of this study is to determine if this combination is safe and effective in this situation especially to increase the rate of pathological complete response (PCR). Women with large tumors and or lymph node involvement at the time of initial diagnosis may benefit from receiving chemotherapy prior to surgery to shrink the tumor and to decrease the amount of tumor involvement before surgery. If chemotherapy given before breast surgery is effective in decreasing the size of the tumor, breast conserving surgery (lumpectomy) may be possible. This new combination may be better tolerated than other commonly used regimens and, to date, appears to be at least as effective.
