Phase II Trial of Neoadjuvant Metronomic Chemotherapy in Triple-Negative Breast Cancer
Phase II Trial of Neoadjuvant Metronomic Chemotherapy in Triple-Negative Breast Cancer
This neoadjuvant chemotherapy protocol focusing on "triple-negative" breast cancers alone
 will gather a foundation of primary tumor and axillary lymph nodal response to primary
 chemotherapy and ongoing correlated disease-free (DFS) and overall survival (OS) outcome
 data. This comparative data can then be used in building subsequent trials.
Women with a diagnosed "triple-negative" proxy of basal-like breast cancer confirmed on a
 core biopsy and larger than 2 cm will be treated neoadjuvantly with the Livingston metronomic
 regimen of 12 weeks of weekly doxorubicin 24 mg/m2 and daily oral cyclophosphamide 60 mg/m2
 followed by 12 successive weeks of taxol 80 mg/m2 and carboplatin AUC 2. Although clinical
 response will be evaluated prior to surgery, the primary end-point is the pathologic
 response. Secondary end-points will be DFS and OS based upon standard of care surveillance. A
 pathologic complete response (pCR) will require no histologic evidence of residual malignant
 cells seen in the primary tumor area specimen or the lymph nodes. Standard of care surgery
 and radiation therapy will be undertaken.
Inclusion Criteria:

 -  Women with Estrogen Receptor (ER), Progesterone Receptor (PR),and HER2 negative
 invasive breast cancer confirmed on core biopsy.(Note: HER2 negative by FISH
 preferred; HER2 0 or 1+ by IHC acceptable)

 -  Primary tumor size 2cm or greater by physical exam or radiographic measurements.(Note:
 Locally advanced T4 or inflammatory breast cancer is eligible.)

 -  Assessment of pre-treatment axillary lymph nodal status (Note: FNA biopsy if palpable
 or sentinel lymph node biopsy (SLNB) if not palpable preferred; clinical exam
 acceptable.)

 -  Absolute neutrophil count > 1500 mm3 and platelet count > 100,000 mm3

 -  Normal myocardial left ventricular function

 -  Serum creatinine < 2.0 mg/dl

 -  Total bilirubin and AST < 3X upper limits normal

 Exclusion Criteria:

 -  Recurrent or metastatic breast cancer findings (Note: If oncologically felt to be a
 second breast primary, patient eligible for this protocol)

 -  Another active cancer present

 -  Medical contraindications to chemotherapy or surgery

 -  First trimester pregnancy

 -  Breast feeding
