简要总结
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.
详细描述
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.
