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

 1. the first diagnosis of invasive breast cancer, confirmed by histology or cytology, and
 surgical resection of the primary lesions before receiving any anti breast cancer
 treatment;

 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);

 4. hormone receptor status is known, lymph node positive or sentinel lymph node negative
 but high risk factors

 5. the eastern oncology cooperative group (ECOG) patients with physical status score was
 0 -2;

 6. baseline LVEF >50%

 7. the relevant institutional review board (IRB) or independent ethics committee (IEC)
 written informed consent

 Exclusion Criteria:

 1. the subjects in pregnancy or lactation;

 2. pregnant women may be within the first 7 days before pregnancy test positive (urine or
 serum).

 3. received chemotherapy, endocrine or anti HER2 anti-tumor therapy;

 4. congestive heart failure, unstable angina, heart failure or myocardial infarction and
 other diseases;

 5. other invasive tumors (including the second primary breast cancer), may affect the
 outcome of the evaluation and program compliance; but the treatment of patients with
 disease free survival at least more than 5 years can be selected;

 6. with chronic liver disease in patients with liver dysfunction and / or with clinical
 manifestations: the serum total bilirubin > 2.5 * ULN; or INR = 1.5 but no bilirubin.
 serum ALT or AST> * 3 * ULN; alkaline phosphatase >2.5 * ULN; ALT or AST can be
 gradually increased, but with gradually increasing fatigue, nausea and vomiting,
 fever, right upper quadrant pain or tenderness

 7. hematopoietic dysfunction, defined as follows: neutrophil count (ANC) <1.5 * 109/L;
 platelet <100 * 109/L; hemoglobin <9 g/dL;

 8. other serious diseases, including: congestive heart failure (heart function NYHA grade
 II, III, IV) or occurred within 6 months of congestive heart failure, unstable angina,
 arrhythmia, myocardial infarction patients can't control or other severe
 cardiovascular disease; breathing at rest or need oxygen therapy; serious infection;
 uncontrolled diabetes;

 9. there is a serious psychological or mental abnormalities, estimated that the
 participants to participate in this study is not strong;

 10. known to study drug allergy;

 11. the past 30 days participated in the study of other drug clinical trials.

 1, failed to complete the clinical trial of at least 1 cycles according to the program, can
 not carry out safety and efficacy evaluation 2, a serious violation of this research
 program, not in accordance with the prescribed dose, method and course of medication.

 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.
