Efficacy and Safety of Eribulin in the Treatment of Advanced Breast Cancer

Chemotherapy is an important means to prolong the survival time of advanced breast cancer. As a new type of microtubule inhibitor, eribulin has a unique mechanism of action. Compared with single drug chemotherapy, it can improve the overall survival time of 2.5 months, increase the clinical benefit rate by 5 times, and the tolerance of eribulin is good. Therefore, the guidelines at home and abroad recommend eribulin for the rescue of advanced breast cancer. However, up to now, there is no large sample data on the efficacy of eribulin combined with anti HER2 targeted therapy in HER2 + metastatic breast cancer, and the efficacy of combined immunotherapy in triple negative metastatic breast cancer. Moreover, as a newly marketed chemotherapy drug in China, the efficacy and safety data of eribulin in Chinese population are relatively lacking. Therefore, we plan to include different types and line numbers of advanced breast cancer patients based on the Chinese population through real-world research, and receive the treatment regimen containing eribulin respectively. In HR + / her2-mbc, we use eribulin monotherapy; in HER2 + MBC, we use eribulin + anti HER2 targeted therapy; in TNBC, we use eribulin + immunotherapy / chemotherapy, The efficacy and safety of eribulin were evaluated.
