Background

The breast cancer is the most common malignant tumor of women all over the world, accounts for about 25 percent of the malignant tumors of the women, is the top of various tumors of the women, and the incidence rate is in a rapid rising trend in recent years. Triple Negative Breast Cancer (TNBC), immunohistochemistry, shows that Estrogen Receptor (ER), Progesterone Receptor (PR), and HER-2 are all Negative. As a subtype of breast cancer, TNBC accounts for 15% to 20% of all breast cancers. TNBC is clinically characterized by more aggressive pathological features, including higher recurrence rate, drug resistance to chemotherapeutic drugs, more frequent distant metastasis (a process in which tumor cells are transferred from an originally occurring site to other sites of the body via an invasion circulatory system and continue to grow, also called malignant metastasis) when diagnosed, and poorer prognosis. Clinical treatment methods for TNBC include surgery, chemotherapy and radiation therapy, with chemotherapy being the primary therapy in medicine. Despite the diversity of chemotherapeutic regimens, 35% of TNBC patients develop recurrent metastases and have a short survival time.

Because the TNBC cell surface has no special cell surface receptor, the triple negative breast cancer has the characteristics of strong invasiveness, advanced recurrence time, high incidence rate of malignant metastasis, rapid disease progression, limited treatment means, poor curative effect, disease-free survival rate, lower overall survival rate, shortened overall survival time and the like. The existing medicine for treating triple negative breast cancer has the defects of high toxicity and low treatment remission rate.
