Primary Chemotherapy With Adriamycin/Cyclophosphamide(AC) vs Taxotere/Xeloda(TX) for Stage II and III Breast Cancer

Breast Cancer Clinical Trial

Official title: A Phase III Randomized Study of Primary Chemotherapy With Adriamycin/Cyclophosphamide(AC) vs Taxotere/Xeloda(TX) for Stage II and III Breast Cancer

Status Completed

Clinical Trial Summary

This is an open labeled phase III randomized trial. The patients with clinical stage II and III will undergo mammotome biopsy of breast tumor for histologic diagnosis, immunohistochemical studies for estrogen receptor(ER), progesterone receptor(PR), HER-2/neu and others. PET results will determine the positivity of lymph node metastasis.

Clinical Trial Description

• Patients will be randomized to receive regimen A (AC) and regimen B(TX), preoperatively,as follows: Regimen A (AC): Intravenous infusion of Adriamycin 60mg/m2 , over 30 min, onD1 and Intravenous infusion of cyclophosphamide 600 mg/m2 over 30 min on D1. Regimen B(TX): Intravenous infusion of Taxotere 75 mg/m2 over 1 hr, on D1, and Xeloda 1000mg/m2.p.o. BID x 14days on D1-D14 The cycle repeats every 3 weeks for 4 times. Premedication for regimen A includes antiemetics, for regimen B, dexamethasone as routinely given.

Patients who do not respond to the initial two cycles of preoperative chemotherapy will undergo operation.

The response rate will be determined by the number of patients with complete and partial responses according to RECIST guidelines. Pathologic complete response is defined as no pathologic evidence of residual disease. Safety will be evaluated by the frequency, severity, and relationship of adverse events graded by NCI Common Toxicity Criteria(CTC) that occur during the treatment and follow-up periods. Time to disease progression will be calculated from the date of study entry to the first objective documentation of progressive disease. Response duration will be measured from the date a patient first fulfills the CR or PR criteria to the first date of objective documentation of disease progression. Survival time will be calculated from the date of study entry to the date of death ;
