Randomised Phase II Trial of Neoadjuvant Weekly Paclitaxel Plus Carboplatin Compared to Weekly Paclitaxel Alone Followed in Both Arms by Doxorubicin and Cyclophosphamide for Operable or Locally Advanced Basal-like Subtype Breast Cancer Correlating BRCA-1 mRNA and Protein Expression With Carboplatin Response

简要总结
RATIONALE: Drugs used in chemotherapy, such as paclitaxel, doxorubicin, cyclophosphamide, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether combination chemotherapy is more effective with or without carboplatin in treating breast cancer.
PURPOSE: This randomized phase II trial is studying giving paclitaxel together with doxorubicin and cyclophosphamide to see how well it works compared to giving paclitaxel together with doxorubicin, cyclophosphamide, and carboplatin in treating women with locally advanced breast cancer that can be removed by surgery.
详细描述
OBJECTIVES:
Primary
- To evaluate tumor pathological complete response rate after neoadjuvant paclitaxel with vs without carboplatin followed by cyclophosphamide and doxorubicin hydrochloride in women with basal-type subtype primary breast cancer.
Secondary
- To evaluate the clinical and pathological overall response rate.
- To evaluate safety and toxicity.
- To evaluate disease-free survival and overall survival.
- To correlate low BRCA1 expression (protein and mRNA), p53 mutation, positive CK5/6, positive CK 14, basal-like gene expression profile, and response to carboplatin-based treatment.

结局指标
主要结局
Pathological complete response rate
时间窗: Pathological response will be assessed by evaluation of surgical specimen after completion of protocol treatment.
