Abstract:

Systemic therapy including chemotherapy, endocrine therapy and targeted therapy, is currently performed to reduce the risk of recurrence and prolong the survival of breast cancer patients. However, almost 40% breast cancer patients suffer recurrence due to drug resistance, suggesting that traditional treatment regimens fail to completely kill tumor cells. The theory of tumor ecology provides a new insight to understand treatment resistance of tumors and find new targets of drugs. According to tumor ecology, the interaction between tumors and surrounding microenvironment can affect the initiation, development and treatment sensitivity of tumors. In this review, the author illustrates the relationship between drug resistance of breast cancer and tumor ecological environment composed of breast cancer cells and microenvironment, and reviews the related clinical research progress, in order to provide references for reversing drug resistance of breast cancer.

Key words: Breast neoplasms, Ecology, Drug tolerance
