Epirubicin Versus Docetaxel Plus Cyclophosphamide in Lymph Node Negative, ER-positive, Her2-negative Breast Cancer

Phase 4

Completed

• Conditions: Breast Neoplasms
• Interventions: Drug: Epirubicin; Drug: Docetaxel; Drug: cyclophosphamide

• Registration Number: NCT02549677
• Lead Sponsor: Ruijin Hospital

Brief Summary

The purpose of this study is to compare the safety and efficacy of epirubicin plus cyclophosphamide versus docetaxel plus cyclophosphamide in lymph node negative, estrogen receptor (ER) positive, human epithelial growth factor receptor 2 (HER2) negative breast cancer patients as adjuvant chemotherapy.

Detailed Description

This is a non-inferiority study. According to previous study results, the investigators hypothesize the incidence of grade 3-4 neutropenia is 40%, with a α of 0.05 and β of 0.8, a sample size of 264 cases if needed.
