Abstract：【Objective】To explore the efficacy and survival status of pyrrotinib combined with chemotherapy in the treatment of human epidermal growth factor receptor 2 (HER2) positive advanced breast cancer. 【Methods】A total of 72 patients with HER2 positive advanced breast cancer admitted to our hospital was randomly divided into observation group and control group, 36 cases in each group. The control group was treated with routine chemotherapy, and the observation group was treated with pyrrotinib combined with chemotherapy. The use of chemotherapy drugs, short-term clinical efficacy, adverse reactions and survival of the two groups were compared.【Results】The clinical control rate in the observation group was 69.44% (25/36), which was significantly higher than 47.22% (17/36) in the control group (P<0.05). There was no significant difference in the incidence of adverse reactions such as nausea, vomiting, hair loss and fatigue between the observation group and the control group (P>0.05). After 6 months of follow-up, the survival rates of the control group and the observation group were 80.00% and 88.24% respectively. There was no significant difference in the survival curve between the two groups (P>0.05). 【Conclusion】Pyrrotinib combined with chemotherapy in the treatment of HER2 positive advanced breast cancer patients can improve the clinical control rate and is safe and reliable. However, the survival rate of patients with follow-up of 6 months after operation is not significantly improved.
