To the Editor:Tumor immune microenvironment plays a key role in breast cancer development and progression,which determines the long-term survival of breast cancer *** data have revealed that the application of cancer immunotherapy has some limitations,including generating weak immune responses due to inadequate delivery of immunostimulants to the immune cells.^([1])Thus,current clinical efforts are primarily focused on developing immune-based chemotherapy that can convert non-responders to responders.^([2])Immunogenic cell death(ICD)is a form of regulated cell death that is sufficient to activate an adaptive immune response.
