Filter by:Breast cancer is the most common malignant tumor in women. EC-TH is one of the standard chemotherapy regimens for HER-2 positive early breast cancer(EBC). Earlier use of trastuzumab may improve DFS rate. In this study, the investigators want to find out whether ACH-TH regimen compared with the EC-TH regimen in HER2+ EBC could improve the pCR rate in neoadjuvant chemotherapy. We update protocol in Sep 2020, because Pertuzumab is approveled by Chinese goverment and coverd by national insurance, dual target therapy with Trastuzumab and Pertuzumab is the standard therapy for neoadjuvant therapy of HER2-positive EBC patients.
This clinical trial is designed as an observational study of 8-9 years of overall duration, but the first results and conclusions could be achieved in 3-4 years. In the first phase, which would last 3-4 years, the investigators will form three predetermined groups of breast cancer patients that would be monitored in the second phase for 5 postoperative years. All patients involved in this trial would undergo a defined protocol. All patients participating in this trial and all members of the investigation team would be completely introduced to the plan and aims of this trial. Two main hypotheses of this trial are that SLNB does not have a negative impact on clinical outcomes (locoregional recurrence and overall survival) in initially node-positive patients who achieved complete clinically axillary remission after neoadjuvant systemic treatment and that lymph node status after neoadjuvant treatment is a significantly more relevant prognostic factor than nodal status at the time of diagnosis. Therefore, the aim is to establish that sentinel lymph node biopsy, in node-positive breast cancer patients that achieve clinical remission after neoadjuvant treatment, is a reliable approach for surgical axillary management. Data would be collected individually for each patient and recorded on appropriate forms. After data completion, the principal investigator would import encoded data into the register. Data collected in this trial would be used for publications.
