简要总结
This randomized phase III trial studies cyclophosphamide and doxorubicin hydrochloride compared with paclitaxel as adjuvant therapy in treating breast cancer in women with 0-3 positive axillary lymph nodes. Giving additional cancer treatment after surgery may help to lower the risk that the cancer will come back (adjuvant therapy). Drugs used in chemotherapy, such as cyclophosphamide, doxorubicin hydrochloride, and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether the standard adjuvant therapy of cyclophosphamide and doxorubicin hydrochloride is more effective than paclitaxel in treating women with breast cancer
详细描述
PRIMARY OBJECTIVES:
I. To determine the equivalence of paclitaxel given every two weeks with cyclophosphamide and doxorubicin hydrochloride (CA) given every two weeks as adjuvant therapy for women with 0-3 positive axillary lymph nodes, for disease-free survival.
II. To determine if longer therapy, 12 weeks, is superior to shorter therapy, 8 weeks, of either CA or paclitaxel for disease-free survival for women with primary breast cancer with 0-3 positive axillary lymph nodes.
SECONDARY OBJECTIVES:
I. To determine the equivalence of paclitaxel given every two weeks with CA given every two weeks, and the potential superiority of longer vs. shorter therapy, in relation to overall survival, local control (regardless of metastatic status) and time to distant metastases (regardless of local recurrence status).

结局指标
主要结局
Duration of Disease Free Survival (RFS)
时间窗: from baseline up to 6.4 years
To determine the equivalence of paclitaxel to CA as adjuvant therapy for women with 0-3 positive axillary lymph nodes, for disease-free survival. Objective progression is defined as the appearance of local (chest wall, axillary, supraclavicular nodes) or distant metastases. The trial is designed to show the equivalence of the experimental agent T with the standard agent combination CA, thus the 4 and 6 course arms of each drug will be combined to conduct this analysis.
Relapse Free Survival (RFS) 4 vs. 6 Cycles
时间窗: from baseline up to 4 years
To determine if longer therapy, 12 weeks, is superior to shorter therapy, 8 weeks, of either CA or paclitaxel for relapse-free survival for women with primary breast cancer with 0-3 positive axillary lymph nodes. An assessment of the superiority of 6 cycles over 4 cycles will be conducted. This analysis combines Arm I and Arm III together, and Arm II and Arm IV together.
次要结局
- Adverse Events(from baseline up to 6 weeks post-treatment)
- Time to Distant Metastases(from baseline up to 15 years)
- Overall Survival (OS) for 4 vs. 6 Cycles(from baseline up to 4 years)
- Overall Survival (OS)(from baseline up to 5 years)
- Local Control(from baseline up to 15 years)
