Comparison Study of Neoadjuvant Paclitaxel Plus Carboplatin/Epirubicin Treatment in Triple-negative Breast Cancer

Phase 2

• Conditions: Triple Negative Breast Cancer
• Interventions: Drug: Paclitaxel and epirubicin; Drug: Paclitaxel plus carboplatin

• Registration Number: NCT01276769
• Lead Sponsor: Chinese Academy of Medical Sciences

Brief Summary

This study is to compare the effective of Paclitaxel combined with Epirubicin and Paclitaxel plus Carboplatin in the neoadjuvant treatment for TNBC. And the investigators hypothesized that paclitaxel combined with carboplatin is more sensitive to TNBC compared with Paclitaxel plus Epirubicin,this study will also have a look into the relation of BRCA1 mutation and sensitive to carboplatin.

Detailed Description

It is know that triple-negative breast cancer(TNBC) is more aggressive than non-triple negative breast cancer in both pathological features and clinical prognosis,and there is no standard chemotherapy regimens especially for TNBC. NCCN guidelines recommends Paclitaxel or Epirubicin based regimens as the preferred regimens both for the adjuvant chemotherapy and the treatment of Recurrence and Metastatic breast cancer.The combination of these two drugs is considered as a strong arrangement and therefore,is common used in Triple negative breast cancer patients because of its poor prognosis.

According to the results of some retrospective studies, platinum-based chemotherapy regimens showed a promising sensitive to Triple negative breast cancer patients compared with regimens without platinum.

This study is to compare the effective of Paclitaxel combined with Epirubicin and Paclitaxel plus Carboplatin in the neoadjuvant treatment for TNBC. And the investigators hypothesized that paclitaxel combined with carboplatin is more sensitive to TNBC compared with Paclitaxel plus Epirubicin,this study will also have a look into the relation of BRCA1 mutation and sensitive to carboplatin.

Arm && Interventions

Group	Intervention	Description
ET	Paclitaxel and epirubicin	The control arm receive the paclitaxel plus epirubicin
PC	Paclitaxel plus carboplatin	the experimental arm which receive the paclitaxel combined with carboplatin

Primary Outcome Measures

Name	Time	Method
Pathology of specimens derived from the breast modified radical mastectomy/Breast-conserving surgery	One week after the surgery	After patients complete the neoadjuvant chemothreapy and receive the surguries,we can get their pathology ，and compare the pCR（pathological complete remission）rates of two amrs

Secondary Outcome Measures

Name	Time	Method
follow-up the patient every 3-6 months to obtain the 3 year-DFS(disease free survival ) and OS(overall survival )	we follow up the patients every 6 month ,up to 3 years
