Abstract: Triple-negative breast cancer (TNBC) can benefit from immunotherapy because of its higher tumor mutational burden (TMB) and tumor-infiltrating lymphocytes. Although immunotherapy has made breakthroughs as an important treatment strategy for TNBC, recent clinical data suggest that a proportion of patients exhibit resistance to immunotherapy, or those who are effective in treatment experience further recurrence or progression. The main reason for these poor prognosis is complex internal or external immune escape mechanisms, which may be caused by abnormal antigen presentation, immunosuppressive tumor microenvironment, interactions with other immune checkpoints, and abnormal activation of tumor cell signaling. However, the research on the resistance mechanism of TNBC immunotherapy is still incomplete. This article will provide a review of the challenges faced by immunotherapy and the potential mechanisms of TNBC develops resistance to immunotherapy.
