Neoadjuvant Treatment of Breast Cancer

Summary

Study Aims 1. To measure the clinic response rates in patients with breast cancer more than 2 cm and/or lymph node positive breast cancer treated with 2-4 cycles of biweekly doxorubicin, cyclophosphamide with Granulocyte-macrophage colony-stimulating factor (GM-CSF) (days 4-13) followed by weekly carboplatin/nab-paclitaxel given for 3 weeks, followed by 1 week of rest, for a total of 9-12 doses. (Her-2 positive patients, in addition, will receive Trastuzumab weekly (12-16 doses) and Her-2 negative patients will receive Bevacizumab (6-8 doses) q 2 weeks). 2. To measure the microscopic pathological response rate of this regimen. 3. To measure toxicity and the delivered dose intensity of this regimen. 4. To assess the association between microscopic pathologic complete response and clinical complete response at the primary tumor site in these patients. 5. To determine whether the GM-CSF increases the post treatment dendritic cells (S100+) percentage in the tumor draining lymph node as compared to pretreatment S100+ cells. 6. To determine whether the patients with a higher percent S100+ have a better clinical, pathological response, Disease Free Survival (DFS), and overall Survival (OS). 7. To determine whether flow cytometry of dendritic cells performed post-treatment in blood sample shows an increase in dendritic cell population compared to pretreatment levels.
