Neoadjuvant Chemotherapy Using Doxorubicin and Paclitaxel in Treating Women With Large Breast Cancer
Neoadjuvant Chemotherapy in Palpable Breast Cancer: Evaluation of Physiologic, Radiologic, and Molecular Markers in Predicting Response
RATIONALE: Drugs used in chemotherapy, such as doxorubicin and paclitaxel, work in different ways to stop tumor cells from dividing so they stop growing or die. Giving chemotherapy before and after surgery may shrink the tumor so it can be removed and may kill any tumor cells remaining after surgery.
PURPOSE: This randomized phase II trial is comparing two different regimens of doxorubicin and paclitaxel to see how well they work in treating women who are undergoing surgery for breast cancer.

OBJECTIVES:
Primary
- Determine whether tumors in women with palpable invasive breast cancer with wild type p53 are more sensitive to doxorubicin than to paclitaxel when given as sequential single-agent neoadjuvant chemotherapy.
- Determine whether tumors with inactivated p53 are more sensitive to paclitaxel than to doxorubicin when given as sequential single-agent neoadjuvant chemotherapy in these patients.
Secondary
- Correlate other biological markers (physiological and molecular) with tumor response in patients treated with these regimens.
- Determine changes in these biological markers during and after neoadjuvant chemotherapy in these patients.
- Compare breast MRI, in terms of assessing tumor response, with physical exam, mammogram, and ultrasound in patients treated with these regimens.
- Determine whether there are MRI indicators (e.g., tumor morphology or lesion enhancement) that are predictive of response in patients treated with these regimens.
OUTLINE: This is a randomized, multicenter study. Patients are stratified according to tumor size (> 5 cm vs ≤ 3-5 cm) and presence of palpable regional lymph nodes (yes vs no). Patients are randomized to 1 of 2 treatment arms.
All patients undergo biopsy, bilateral mammogram, MRI, ultrasound, blood marker, molecular (gene microarrays and functional p53 status), and physiologic studies before initiation of neoadjuvant chemotherapy. Some of these studies are repeated after completion of treatment with the first chemotherapeutic agent and after completion of treatment with the second chemotherapeutic agent as outlined below.
- Arm I: Patients receive doxorubicin IV on days 1, 15, 29, and 43. Patients with no residual tumor (indicated by clinical evaluation and radiologic studies) after completion of doxorubicin undergo definitive surgery. After surgery, patients receive paclitaxel IV over 1 hour on days 1, 8, 15, 22, 29, 36, 43, 50, and 57.
Patients with residual tumor > 2 cm after completion of doxorubicin undergo 8-12 core needle biopsies. Patients with residual tumor < 2 cm after completion of doxorubicin undergo 4-6 core needle biopsies. After core needle biopsies, patients receive paclitaxel as above.
- Arm II: Patients receive paclitaxel IV over 1 hour on days 1, 8, 15, 22, 29, 36, 43, 50, and 57. Patients with no residual tumor (indicated by clinical evaluation and radiologic studies) after completion of paclitaxel undergo definitive surgery. After surgery, patients receive doxorubicin IV on days 1, 15, 29, and 43.
Patients with residual tumor > 2 cm after completion of paclitaxel undergo 8-12 core needle biopsies. Patients with residual tumor < 2 cm after completion of paclitaxel undergo 4-6 core needle biopsies. After core needle biopsies, patients receive doxorubicin as above.
In both arms, treatment continues in the absence of disease progression or unacceptable toxicity.
Samples from core needle biopsies are analyzed by microarray analysis for gene expression profiles.
Patients are followed every 6 months for 5 years.
PROJECTED ACCRUAL: A total of 100 patients (50 per treatment arm) will be accrued for this study within 4-5 years.
