[Immunotherapy possibilities and results in breast cancer]

In recent years, a number of tumor types have shown significant therapeutic benefit with immunotherapy. Breast cancer has not been regarded traditionally as a typical immunogenic tumor, however, based on results so far, immunotherapy may play a role in the therapy. The most important change in attitude is that the target of therapy is not the disease but the host. A better understanding of the host's immune system and the process between the tumor and host provides an opportunity for therapeutic intervention, in this case (re-)activating anti-tumor immune processes. The purpose of this summary is to briefly summarize for clinicians the basics of anti-tumor immunity process, the available clinical results and the major therapeutic options in this field.
