Standard postoperative adjuvant therapy significantly improves disease-free survival and overall survival of patients. The factors that determine whether breast cancer should receive standard adjuvant chemotherapy, radiotherapy, endocrine therapy and targeted therapy after surgery are the following: primary mass size, number of axillary lymph node metastases, pathological type and histological grading, estrogen and progesterone receptor status (ER and PR), epidermal growth factor receptor status (HER-2) and patient’s age, therefore, these indicators must be clarified as much as possible after surgery and A reasonable and orderly comprehensive treatment plan must be formulated based on the above indicators: including the rational choice of chemotherapy regimen, whether to administer radiotherapy, whether to administer targeted therapy, the choice of different endocrine therapeutic agents and the duration of treatment, and the reasonable treatment sequence. After surgery in local hospitals, breast cancer patients should bring their primary tumor wax lumps (pathology consultation and detection of prognostic indicators) and copies of hospital medical records (including pathology reports, chemotherapy drugs and doses if chemotherapy has been started) when they come to our hospital for accurate treatment assistance.
