Breast Cancer,Her2 Positive Clinical Trial
Official title:
Comparing the Efficacy and Security of Nab-PHP and TCbHP in Neoadjuvant Chemotherapy for HER2 Positive Operable Breast Cancer , A Multicenter, Randomized, Phase III Clinical Trial
At present, trastuzumab combined with patuzumab has become the standard neoadjuvant therapy for high-risk HER2 positive breast cancer. TCbHP has been the standard choice of neoadjuvant therapy for HER2 positive breast cancer patients with early high-risk or locally advanced HER2 positive breast cancer. Whether nab-PHP can achieve the same effect as TCbHP is still uncertain.

Clinically measurable lesions: measurable lesions revealed by ultrasound, molybdenum target or MR (optional) within 1 month before randomization 5. Organ and bone marrow function test within one month before chemotherapy showed no chemotherapy contraindication - Absolute value of neutrophil count = 2.0×10^9 / L - Hemoglobin = 100g / L - Platelet count = 100×10^9 / L - Total bilirubin < 1.5 ULN (upper limit of normal value) - Creatinine < 1.5 × ULN - AST/ALT < 1.5×ULN 6. Echocardiography: left ventricular ejection fraction (LVEF = 55%) 7. For women of childbearing age, serum pregnancy test was negative 14 days before randomization 8. ECOG score of 0 or 1 9. Signed the informed consent form prior to patient entry Exclusion Criteria: 1. Metastatic breast cancer (Stage IV) 2. Chemotherapy, endocrine therapy, targeted therapy and reflexotherapy have been used for this disease 3. The patient had a second primary malignant tumor, except for the well treated skin cancer 4. Patients who had undergone major surgery unrelated to breast cancer within 4 weeks before enrollment, or had not recovered completely from such operations 5. Serious heart disease or discomfort, including but not limited to the following diseases: - History of heart failure or systolic dysfunction (LVEF < 50%) - high risk uncontrolled arrhythmias such as atrial tachycardia, resting heart rate > 100 BPM, significant ventricular arrhythmias (e.g., ventricular tachycardia) or higher-level atrioventricular block (i.e., mobitz II second degree atrioventricular block or third degree atrioventricular block) - angina pectoris requiring anti angina drugs - Heart valve disease with clinical significance - ECG showed transmural myocardial infarction - Poor control of hypertension (systolic blood pressure > 180 mmHg and / or diastolic blood pressure > 100 mmHg) 6. Due to serious and uncontrollable other medical diseases, the researchers believe that there are chemotherapy contraindications 7.
