摘要: New York esophageal squamous cell carcinoma 1 (NY-ESO-1, CTAG1B) is a cancer-testis antigen and currently focus of several targeted immunotherapeutic strategies. We performed large-scale immunohistochemical expression study NY-ESO-1 using tissue microarrays mesenchymal tumors from three institutions in an international collaboration. A total 1132 intermediate malignant 175 benign lesions were enrolled this study. Immunohistochemical staining was on monoclonal antibody for NY-ESO-1. Among tumors, myxoid liposarcomas showed the highest positivity (88%), followed by synovial sarcomas (49%), myxofibrosarcomas (35%), conventional chondrosarcomas (28%). Positivity remaining consistently low, no immunoreactivity observed lesions. On basis these findings, nearly 90% liposarcomas, as well significant proportion sarcomas, myxofibrosarcomas, are good candidates immunotherapy targeting
