A Randomized Controlled Trial of HER-2 Positive Breast Cancer Patients Treated With Lapatinib vs Herceptin

This is a randomized controlled trial of HER-2 positive breast cancer patients treated with lapatinib and paclitaxel vs herceptin and paclitaxel with sequential and synchronous anthracycline

This is a randomized controlled trial of HER-2 positive breast cancer patients treated with lapatinib and paclitaxel vs herceptin and paclitaxel with sequential and synchronous anthracycline. Safety and efficacy are the primary endpoint. The positive expression of HER2 was confirmed by postoperative pathology in patients with breast adenocarcinoma (IDC). Patients who had not received any chemotherapy and targeted anti HER2 therapy.

In this study, the non inferiority design method, according to the wishes of patients and signed informed consent, randomly into the group, a total of 482 patients were enrolled in the trial group: the control group =1:1. The subjects were followed up for a total of 1 years, until the disease progressed, and the toxicity was not tolerated.

We want to study 84 months. The follow-up period was 5 years (the first adjuvant treatment time to the last follow-up) or the researchers decided to end the study.

2. female patients, aged 18 years and less than 80 years of age;
3. surgical resection of the primary tumor pathological examination, showed HER2 positive (defined as immunohistochemistry \[IHC\] 3+ or fluorescence in situ hybridization (FISH) positive);

Patients will receive lapatinib treatment, until a predetermined end end point, or development of unacceptable toxicity, or withdrawal of consent, or illness or death, to appear before the subject.
