研究组 & 干预措施
Group A
The patient received six cycles of neoadjuvant therapy (pyrotinib and trastuzumab purplitol and platinum-based drugs) and underwent radical mastectomy (breast-conserving surgery or total mastectomy) after treatment. After the operation, the doctor will give the corresponding treatment according to the results of the postoperative medical examination
干预措施: Trastuzumab intravenous drip/Trastuzumab Subcutaneous Injection (Drug)
Group B
The patient went on to complete six cycles of neoadjuvant therapy (pyrotinib and trastuzumab) and underwent radical mastectomy (breast-conserving surgery or total mastectomy) after treatment. After the operation, the doctor will give the corresponding treatment according to the results of the postoperative medical examination
干预措施: Trastuzumab intravenous drip/Trastuzumab Subcutaneous Injection (Drug)
