Locally Advanced Breast Cancer: Individualized Treatment Based On Tumor Molecular Characteristics
Breast Cancer

About this trial
This is an interventional treatment trial for Breast Cancer focused on measuring Locally Advanced Breast Cancer
Eligibility Criteria
Inclusion Criteria:
- Biopsy proven locally advanced breast cancer: STAGE IIB (T must be > 3.0 cm, N0), IIIA (T0N2, T1N2, T2N2, T3N1), IIIB (T4N0-2).
- HER-2/neu positive ( DAKO 3+ by Immunohistochemistry or FISH positive if Dako 2+)
- Metastatic breast cancer: limited to the subset of patients with intact breast, locally advanced tumor and involved ipsilateral supraclavicular nodes.
- Measurable disease required according to the RECIST criteria (Response Evaluation Criteria in Solid Tumors)
- Adequate laboratory values:
- Hgb > 10
- ANC(Absolute Neutrophil Count) > 1500
- Platelets > 150,000
- Cr < 1.5
- Liver function < 3 X normal.
- Patient > 18 years of age.
- Medically and psychologically able to comply with all study requirements.
- ECOG (Eastern cooperative Oncology group) performance score 0-1.
- Signed informed consent.
Exclusion Criteria:
- Stage 0, Stage I, Stage IIA.
- Previous XRT(Radiation therapy) or chemotherapy.
- Presence of distant metastases documented clinically or radiographically with the exception of ipsilateral supraclavicular nodes.
- Inflammatory breast cancer.
- Prior unanticipated severe reaction to fluoropyrimidine therapy or known hypersensitivity to 5-fluorouracil.
- Exclude pregnant or lactating woman.
- Woman of childbearing potential with either a positive or no pregnancy test at baseline.
- Woman of childbearing potential not using a reliable and appropriate contraceptive method.
- (Postmenopausal women must have been amenorrheic for at least 12 months to be considered of non-childbearing potential).
- Patient will agree to continue contraception for 30 days from the date of the last study drug administration.
- Serious concurrent infections.
- Clinically significant cardiac disease not well controlled with medication (e.g. congestive heart failure, symptomatic coronary artery disease and cardiac arrhythmias ) or myocardial infarction within the last 12 months.
- Patients who have had an organ allograft.
- Patients with severe renal impairment (creatinine clearance below 30 mL/min [Cockcroft and Gault43]). In patients with moderate renal impairment (creatinine clearance 30-50 mL/min [Cockcroft and Gault43]) at baseline, a dose reduction to 75% of the XELODA starting dose is recommended. In patients with mild renal impairment (creatinine clearance 51-80 mL/min) no adjustment in starting dose is recommended.
- In phase I studies, those with any abnormal renal function, since toxicity will likely be affected by the presence of any significant renal dysfunction.
- Cockcroft and Gault Equation:
- (140 - age [yrs]) (body wt [kg])
- Creatinine clearance for males = --------------
- (72) (serum creatinine [mg/dL])
- Creatinine clearance for females = 0.85 x male value

Arm 1 Capecitabine and RT
Arm 2 Paclitaxel/Trastuzumab and RT
Arm 3: Paclitaxel and RT
Arm 4: Paclitaxel/Trastuzumab and RT
Her-2/neu negative patients will be given Capecitabine (xeloda, 750mg/m2 twice daily orally. Treatment should begin on day 1 of radiation therapy. The two doses should be taken about 30 minutes after eating (eg. after breakfast and after dinner). Treatment will be given for 10 weeks (for 6 weeks during radiation and for 4 weeks after radiation).
Trastuzumab (Herceptin®) will begin on day 1 of radiation therapy and be administered weekly to Her-2/neu Positive patients. The first dose will be 4mg/kg given IV over 90 minutes. Weekly doses will be 2 mg/kg/week IV over 30 minutes.Paclitaxel 30 mg/m2 twice per week given IV over 1 hour.
Paclitaxel 30 mg/m2 twice per week given IV over 1 hour to Her-2/neu negative patients. Treatment will be initiated during the first week of radiation therapy and should be administered on a Monday/Thursday or Tuesday/Friday schedule.
Trastuzumab (Herceptin®) tx will be administered weekly, together with one of the 2 weekly doses of Paclitaxel to Her-2/neu Positive patients. The 1st dose will be 4mg/kg given IV over 90 minutes. Weekly doses will b given at a dose of 2 17mg/kg/week IV over 30 minutes. The Tx with Trastuzumab will continue weekly after the completion of the radiation tx until surgery & thereafter as per std of care up to 1 yr post surgery.Paclitaxel 30 mg/m2 twice per week given IV over 1 hour. Tx will be administered on a Monday/Thursday or Tuesday/Friday schedule.The radiation treatment will start within 1 week from the first dose of paclitaxel and trastuzumab.
