Research Abstract |
We performed phase I clinical peptide vaccination trials for patients with disseminated synovial sarcoma or osteosarcoma. For synovial sarcoma, the trial was completed and the safety and efficacy of SYT-SSX peptide vaccination was confirmed. For osteosarcoma, the trial is continued. We identified cancer-stem like cells from malignant fibrous histiocytoma of the bone and epithelial sarcoma. Furthermore, we established autologous cytotoxic T-lymphocyte clone recognizing cancer-stem like cells in the context of HLA class I. These observations open the door toward immunotherapy targeting cancer-stem like cells.
