Evaluation of Differing Taxanes/Taxane Combinations on the Outcome of Patients With Operable Breast Cancer

Primary Objectives:

• Determine the impact of each regimen on the disease free and overall survival of patients with operable breast cancer.
• Determine the ability of docetaxel/capecitabine to downstage primary breast cancer when administered in the neoadjuvant setting when compared with weekly paclitaxel.
• Determine the ability of each regimen to enhance breast conservation therapy when administered in the neoadjuvant setting. (See protocol text for additional objectives and details).

Study Overview

• Status: Completed
• Conditions: Breast Cancer
• Intervention / Treatment: Drug: Paclitaxel; Drug: Docetaxel; Drug: Capecitabine

Detailed Description

Before the study, participants will have a complete physical exam, including blood tests and a chest x-ray. A mammogram and a sonogram of the breast and armpit will be done to record tumor size (for patients who have not had surgery). Sonography of the liver or a CT scan of the abdomen will also be done. In some patients who have not had surgery, 3-4 samples of the breast tumor will be taken to help confirm the diagnosis of breast cancer. A biopsy needle will be used to collect the samples.

During the study, participants will have blood tests done before each dose of chemotherapy. For participants who have not had surgery, a mammogram and sonogram will be done of the breast and armpit after completion of paclitaxel or docetaxel/capecitabine and after completion of fluorouracil, cyclophosphamide, and epirubicin (FEC). These studies will help doctors to keep track of the tumor size and help with the final decision whether to remove all or part of the breast and nearby lymph nodes after completion of chemotherapy.

Participants in this study will be randomly assigned (as in the toss of a coin) to one of two treatment groups. There is an equal chance of being in either group.

Participants in Group I will receive paclitaxel once a week. The drug will be given through a plastic tube in a vein over 1 hour for a total of 12 treatments. Before each treatment, patients will receive the drug Decadron (dexamethasone) through the vein and may receive Zofran (ondansetron), Benadryl (diphenhydramine hydrochloride) and/or cimetidine to help decrease the risk of side effects from paclitaxel.

Participants in Group II will receive docetaxel and capecitabine. Docetaxel will be given once every 3 weeks. Docetaxel will be given through a plastic tube in the vein over 1 hour. Capecitabine will be started the same day docetaxel is given. This medicine is given in a pill form. The doctor will prescribe a dose of these pills based upon body weight and height. Participants will take several pills two times a day for 14 days. Participants will then not take any capecitabine pills for one week, until the next dose of docetaxel is given. This combination of docetaxel and capecitabine will be given four times (over a period of 12 weeks). Before each treatment, patients will receive the drug Decadron (dexamethasone) by mouth.

After treatment with either paclitaxel or docetaxel/capecitabine, all participants will receive the drugs FEC through a plastic tube into a vein. All of these drugs will be given once every three weeks for a total of 4 treatments (12 weeks total). Decadron (dexamethasone), Zofran (ondansetron) and Benadryl (diphenhydramine hydrochloride) will be given before the chemotherapy to help decrease the risk of side effects.

Participants who have a Her-2/neu positive cancer will potentially be eligible to receive trastuzumab therapy for 1 year. This medicine is given through a vein either once a week (over 30 minutes) or once every 3 weeks (over 30 minutes). Your doctor will discuss whether this medicine is appropriate for you.

After all treatment is done, participants whose tumors are sensitive to hormones (estrogen) will take a pill to help decrease the amount of hormone (estrogen) that can reach any tumor cells. This pill will be taken once a day for 5 years.

Participants who have not completed surgery for their cancer before receiving the chemotherapy described above will have surgery to remove all or part of the breast that has cancer. If there are signs that the lymph nodes in the armpit (axilla) contain cancer, these lymph nodes will also be removed.

After chemotherapy and surgery, or after completion of chemotherapy (patients who had surgery done first), participants may then receive radiation treatment to the breast area and armpit once a day (Monday through Friday) for 5-6 weeks.

After the study, participants will return for checkups every 3-4 months during Years 1 and 2, every 6 months during years 3 and 4 and yearly after that. During the check-ups participants will talk with and be examined by their physician. Once a year, patients will have yearly mammograms (as needed), chest-x rays, and blood tests.

This is an investigational study. All of the drugs in this study are approved by the FDA for treatment of breast cancer. A total of 930 patients will take part in this study. All will be enrolled at M. D. Anderson.

Description

Inclusion Criteria:

1. Patients with histologic confirmation of invasive, but non-inflammatory carcinoma of the breast.
2. Stage I (T1N0) are not eligible for the neo-adjuvant portion of the protocol.
3. High-risk patients (patients with any of the following: high proliferation rate - Ki67 >35% or poorly differentiated tumors (black's modified grade 3); ER/PR negative; lymphovascular invasion) with stage I disease are eligible for adjuvant therapy.
4. Patients with pure mucinous carcinomas, tubular carcinomas or pure medullary carcinomas are eligible if the patient's tumor is larger than 3 cm in size or if the patient has tumor involvement of the lymph nodes (>2mm).
5. Patients with bilateral breast cancers are eligible.
6. Patients with pN2a (metastasis in four to nine axillary lymph nodes) are eligible as are patients with pN3a (ten or more axillary lymph nodes). Patients with infraclavicular lymph node involvement are NOT eligible.
7. Patients must have clinically measurable disease to be treated in the neoadjuvant setting. This includes patients with a non-palpable primary who have histologically proven lymph node (LN) involvement that is clinically palpable and measurable by ultrasound
8. Histologic confirmation of invasive tumor will be done by core needle biopsy for patients with intact primary tumors. If patients have undergone adequate core biopsy prior to evaluation at MDACC, repeat core biopsy is optional.
9. Patients must sign an informed consent indicating that they are aware of the investigational nature of the study, in keeping with institutional policy.
