RESUMO
Objective:To investigate the effect of huaier granule combined with docetaxel + epirubicin + cyclophosphamide (TEC) neoadjuvant chemotherapy on the disease control rate and the levels of extracellular fragment of human epidermal growth factor receptor 2 (HER2-ECD) and tumor abnormal protein (TAP) in patients with advanced breast cancer.Methods:From April 2013 to June 2016, 94 patients with advanced breast cancer in Shengjing Hospital Affiliated to China Medical University were selected and randomly divided into observation group ( n=47) and control group ( n=47). The control group was treated with TEC neoadjuvant chemotherapy, and the observation group was treated with TEC neoadjuvant chemotherapy combined with huaier granules for 12 weeks. The curative effect, incidence of adverse reactions, cellular immune function indexes (CD8 + , CD4 + , CD4 + /CD8 + ), serum HER2-ECD and TAP levels were compared before and 12 weeks after treatment. The patients were followed up for 3 years after treatment, and the 1-year, 2-year and 3-year survival rates were compared between the two groups. Results:After 12 weeks of treatment, the disease control rate of the observation group was higher than that of the control group, with statistically significant difference ( P<0.05); during the treatment, the incidence of gastrointestinal reaction, neutropenia, thrombocytopenia and abnormal liver function of the observation group was lower than that of the control group, with statistically significant difference ( P<0.05); after 12 weeks of treatment, the serum CD8 + level of the observation group was lower than that of the control group, and the serum CD4 + , CD4 + /CD8 + level was higher than that of the control group, with statistically significant difference ( P<0.05); after 12 weeks of treatment, the serum levels of HER2-ECD and TAP in the observation group were lower than those in the control group, with statistically significant difference ( P<0.05); the 3-year survival rate in the observation group was higher than that in the control group, with statistically significant difference ( P<0.05). Conclusions:Huaier granules combined with TEC neoadjuvant chemotherapy in patients with advanced breast cancer can reduce serum HER2-ECD, TAP levels, which can enhance the immune function of the body, reduce the toxic and side effects, improve the long-term survival rate, and have a significant effect.
