摘要To the Editor:Triple-negative breast cancer(TNBC)remains one of the most formidable clinical challenges in oncology.Due to the absence of estrogen receptor,progesterone receptor,and human epidermal growth factor receptor(HER2)expression,TNBC is intrinsically insensitive to endocrine therapies and HER2-targeted agents.Although immune checkpoint blockade(ICB)has transformed cancer therapy,its efficacy in TNBC is often limited by an“immune-cold”microenvironment characterized by scarce tumor-infiltrating lymphocytes and dominant immunosuppressive(Keenan&Tolaney,2020).
