Zusammenfassung: Genetics have a role in the presence of breast cancer, while the potential role of the immune system leads to consideration of immunotherapy in the treatment of the disease, particularly in metastatic triple-negative breast cancer. The sixth volume of the "Interdisciplinary Cancer Research" series, entitled "Breast Cancer Genetics, Immunology, and Immunotherapy: An Interdisciplinary Approach" publishes comprehensive volumes on immune and genetic mechanisms of breast cancer diagnosis and prognosis. The role of molecular genetics, interleukins, chemokine receptor, and tumor-infiltrated lymphocytes-TILS in breast cancer are explained. Targeting myeloid determinants, SiRNA loaded in drug delivery nanosystems, nucleic acid and drug dual agent nanoplatforms, and oncolytic virotherapy are also discussed in the treatment of breast cancer, particularly in multidrug resistant and metastatic breast cancer. This interdisciplinary series is of special value to researchers working on immunology, genetics, and practitioners working on oncology. This is the main concept of Cancer Immunology Project (CIP), which is a part of Universal Scientific Education and Research Network (USERN). This interdisciplinary book will be of special value to researchers, oncologists, geneticists, and immunologists who wish to extend their knowledge on breast cancer
