摘 要:Immune-based therapy for solid tumors is a promising area of research, providing the potential for cell-mediated immunotherapies to provide long-lived protection against various stage cancer. Unfortunately, even the most successful clinical trials using T cells or dendritic cells (DC) only show objective response rates in <50% of patients. This is due, in part, to a variety of tumor-derived immunosuppressive mechanisms that arise in cancer patients, rerendering antitumor immune responses ineffective. In addition, epidemiological studies have demonstrated that obese individuals face an increased risk of developing cancers, including breast cancer. The reasons for this are likely complex and multi-factorial, , but a state of generalized immune suppression may contribute to these findings. Regardless of the body-mass index of the patient, successful long-term treatment of breast cancer must not only reduce the localized tumor burden, but must also target undetected or known metastases that may exist at the time the primary tumor is identified and treated.
