Clinical Observation of Zhengyuan Capsule Combined with Neoadjuvant Chemotherapy for Triple-Negative Breast Cancer

OBJECTIVE: To study the clinical effect of Zhengyuan capsule combined with neoadjuvant chemotherapy in the treatment of triple-negative breast cancer (TNBC). METHODS: From September 2014 to September 2017, 120 TNBC patients who underwent radical mastectomy in our hospital were randomly divided into control group (n = 60) and observation group (n = 60). The short-term curative effect, the incidence of toxicity and side effects, and the score of quality of life of the patients were compared. Both recurrence and metastasis rates were also analyzed. RESULTS: The combined treatment of Zhengyuan capsule with neoadjuvant chemotherapy significantly improved the objective remission rate (70.00% in the observation group versus 40.00% in the control group) (P < 0.05). Moreover, this combined treatment significantly decreased the total incidence of side effects (35.00% versus 75.00%). Accordingly, the score of quality of life was also increased in patients treated with Zhengyuan capsule plus neoadjuvant chemotherapy (P < 0.05). Furthermore, supplementation of Zhengyuan capsule can significantly suppress both the recurrence and metastasis rate of TNBC in patients treated with neoadjuvant chemotherapy after radical mastectomy in following 3 years (30.00% versus 10.00%, P < 0.05). CONCLUSION: Zhengyuan capsule effectively improves the short-term curative effect, reduces the side effects of chemotherapy, and improves the quality of life of patients treated with neoadjuvant chemotherapy after radical mastectomy. More importantly, this combined treatment can also reduce the long-term recurrence and metastasis of TNBC.
