INTRODUCTION: Myxoid liposarcoma (MLS) is a common lipogenic sarcoma, which is difficult to diagnose in small specimens. New York oesophageal squamous cell carcinoma 1 (NY-ESO-1) is a cancer-testis antigen expressed in neoplastic tissue. In this study, NY-ESO-1 expression was assessed in various soft tissue tumors (STTs), and we also evaluated its diagnostic utility.
METHODS: We included 434 cases of STTs for collection of clinicopathological data. Tissue microarrays were designed, and immunostaining for NY-ESO-1 was examined. We investigated the correlation between NY-ESO-1 expression and various clinicopathological parameters. We also evaluated the role of NY-ESO-1 as a diagnostic marker for MLS and its possible use in prognostication.
RESULTS: Sixty-four of the 434 STTs (14.75%) were immunoreactive for NY-ESO-1, and the most frequent type of tumor in the NY-ESO-1 positive group was MLS (70.3%, 45/64), followed by synovial sarcoma (17.2%, 11/64). MLS showed 72.6% (45/62) immunopositivity for NY-ESO-1. The sensitivity and specificity of NY-ESO-1 expression for the diagnosis of MLS were 84.4% and 100%, respectively, compared to DDIT3 fluorescence in situ hybridization. When restricting analysis to the MLS (n=62), the NY-ESO-1 positive group had a poor overall survival (OS) rate (P=0.039).
CONCLUSION: NY-ESO-1 was substantially and widely expressed in the majority of MLS cases. NY-ESO-1 positivity by IHC staining was also a predictor of a poor OS in patients with MLS. It is possible to use NY-ESO-1 for diagnosis and for predicting a prognosis in patients with MLS, and it may be used as a therapeutic target.
