Sarcomas and the immune system: implications for therapeutic strategies.

Soft-tissue sarcomas are a heterogeneous group of tumors that are capable of generating host immune responses. Historically the role of antitumor immunity was first studied in soft-tissue sarcomas. Subsequent in vitro studies, preclinical models, and clinical observations have provided ample evidence for an immunologic approach to sarcoma treatment. Initial clinical trials involving vaccines and adoptive immunotherapy have demonstrated promising results. The continued search for sarcoma tumor-associated antigens as specific targets is central to the clinical translation of effective immunotherapies. Copyright Â
