Breast Cancer Clinical Trial
Paclitaxel and Radiation Therapy in Treating Patients Undergoing Surgery for Stage II or Stage III Breast Cancer
Summary
RATIONALE: Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving paclitaxel and radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving chemotherapy after surgery may kill any tumor cells that remain after surgery.
PURPOSE: This clinical trial is studying how well giving paclitaxel together with radiation therapy works in treating patients undergoing surgery for stage II or stage III breast cancer.
Full Description
OBJECTIVES:
Primary
Evaluate the efficacy of paclitaxel and concurrent radiotherapy (as measured by pathologic response rates) in patients with stage II or III breast cancer.
Secondary
Evaluate the toxicities of this treatment regimen.
Correlate paclitaxel-induced tumor response with local recurrence-free survival, distant disease-free survival, and overall survival.
Evaluate protein expression profiles by mass spectrometry in biopsy material and blood specimens collected before and after treatment with paclitaxel.
OUTLINE:
Neoadjuvant chemotherapy: Patients receive paclitaxel IV over 3 hours on day 1. Treatment repeats every 21 days for 3 courses in the absence of disease progression or unacceptable toxicity.
Chemoradiotherapy: Beginning 3-4 weeks after completion of neoadjuvant chemotherapy, patients receive paclitaxel IV over 1 hour twice weekly and undergo radiotherapy once daily, 5 days a week, for 6½ weeks.
Surgery: At 6-8 weeks after completion of chemoradiotherapy, patients undergo surgical resection (e.g., modified radical mastectomy or lumpectomy and axillary node dissection).
Adjuvant chemotherapy: Beginning 4-6 weeks after surgery, patients receive doxorubicin hydrochloride IV over 20 minutes and cyclophosphamide IV over 1 hour on day 1. Treatment repeats every 3 weeks for 4 courses in the absence of disease progression or unacceptable toxicity.
Hormonal therapy: After completion of adjuvant chemotherapy, patients with estrogen receptor- and/or progesterone receptor-positive tumor receive hormonal therapy at the discretion of the treating physician.
Patients undergo blood and tissue sample collection periodically to analyze changes in cell cycle by flow cytometry; antibody assays; kinase assays for cyclin B1/CDC2; genetic assays for p53, p21, and other molecular markers; and protein expression assays by mass spectrometry.
After completion of study therapy, patients are followed periodically.
Eligibility Criteria
DISEASE CHARACTERISTICS:
Histologically or cytologically documented invasive carcinoma of the breast*
Tumor ≥ 2 cm in greatest dimension (e.g., T2-4) and any nodal status (e.g., N0-3), including locally advanced disease, as defined by the following criteria:
Primary tumor ≥ 5 cm
Tumor of any size with direct extension to the chest wall or skin
Inflammatory breast cancer (T4d)
Metastasis to ipsilateral internal mammary node
