  • Research progress of cancer-associated fibroblasts in breast cancer metastasis and drug resistance

    ObjectiveTo summarize the latest research progress and related mechanisms of cancer-associated fibroblasts (CAFs) in invasion, metastasis and drug resistance of breast cancer, so as to seek the best treatment strategy for patients with breast cancer metastasis and drug resistance. MethodThe literatures about CAFs research in breast cancer in recent years were searched and summarized. ResultsCAFs was the main stromal cell in tumor microenvironment (TME). By changing TME, the biological characteristics of CAFs could be changed and the growth and invasion of breast cancer cells could be induced. CAFs in breast cancer promotes the invasion and metastasis of breast cancer cells by interacting with inflammatory factors and promoting the formation of pre-transplantation ecosystems, and CAFs also mediates chemotherapy resistance to breast cancer, target resistance, endocrine resistance, and radiation resistance through the secretion of various cellular factors. ConclusionsAt present, some progress has been made in the research of CAFs in breast cancer, but there is still a certain gap to clinical application CAFs has a variety of functional phenotypes, so it is necessary to identify and characterize specific CAFs subtypes when studying new anti-CAFs therapeutic strategies. It has been proved that CAFs has great potential as a specific target for breast cancer treatment, but CAFs still lacks specific biomarkers. Therefore, an in-depth understanding of the biological characteristics and heterogeneity of CAFs can provide a reliable theoretical basis for developing drugs targeting CAFs.
