Study Description

Brief Summary:

S-1 is a newly developed novel oral dihydrouracil dehydrogenase inhibiting fluoro-pyrimidine drug consisting of i M tegafur (FT), 0.4 M 5-chloro-2, 4-dihydroxypyrimidine (gimeracil), and 1 M potassium oxonate (oteracil), with efficient antitumor activity and low gastrointestinal toxicity. Several studies have proved the safety and efficacy of single agent S-1 in metastatic breast cancer. This study is designed to further investigate and compare the efficacy and safety of Epirubicin-cyclophosphamide-S-1(ECS) vs. Epirubicin-cyclophosphamide-5-fluorouracil (ECF) as neoadjuvant chemotherapy in patients with local advanced breast cancer.

Arms and Interventions

Arm	Intervention/treatment
Experimental: Epirubicin-cyclophosphamide-S-1( ECS); S-1(SuLi,QILU Pharmaceutical co.ltd ) was given at a standard dose of 40 mg/m2 twice daily in cycles of 14-day consecutive administration followed by a 14-day rest, combined with by epirubicin(80mg/m2, d1 and d8 respectively) and cyclophosphamide(500mg/m2, d1, infusion). The chemotherapy was applicated 4 cycles 4-weekly.

Active Comparator: Epirubicin-cyclophosphamide-5-FU (ECF); 5-FU was given at a standard dose of 500mg/m2 (infusion, d1, d8 respectively), combined with by epirubicin(80mg/m2, d1 and d8 respectively) and cyclophosphamide(500mg/m2, d1, infusion). The chemotherapy was applicated 4 cycles 4-weekly.	Drug: 5-FU; 5-FU was given at a standard dose of 500mg/m2 (infusion, d1, d8 respectively),

Outcome Measures

Primary Outcome Measures :

1. Pathological complete response [ Time Frame: 12 weeks ]

   Pathological complete response (pCR=ypT0 ypN0) rates of neoadjuvant treatment No microscopic evidence of residual invasive or non-invasive viable tumor cells in all resected specimens of the breast and axilla.

   Pathological response will be assessed considering all removed breast and lymphatic tissues from all surgeries.

   The primary endpoint will be summarized as pathological complete remission rate for each treatment group.

   Ultrasonic examination will be performed every 2 cycles of treatment for efficacy evaluation.

Secondary Outcome Measures :

1. Disease-free Survival [ Time Frame: 5 years ]

   The length of time after primary treatment for a cancer ends that the patient survives without any signs or symptoms of that cancer.

   Evaluation will be performed every 2 cycles of treatment during therapy, and follow-up will be performed every 3 months after therapy

2. Tolerability and safety [ Time Frame: 12 weeks ]
   Reference to NCI Common Toxicity Criteria for Adverse Effects (CTCAE) v 3.0. The endpoint will be summarized as events rate (%) for each treatment group
