Expression data from 34 Synovial Sarcomas

ABSTRACT: Background: Synovial sarcoma (SS) occur in children as well as in adults, although metastatic events are much more common in the latter. Whereas the importance of the t(X;18) translocation in SS oncogenesis is well established, the genetic basis of SS metastasis is still poorly understood. We recently reported expression (CINSARC) and genomic (GI) prognostic signatures related to chromosome integrity in sarcomas and gastrointestinal stromal tumors (GISTs). Here we investigate whether these signatures can also predict outcomes in SS. Methods: One hundred primary untreated SS were selected for expression and genomic profiling in a training/validation approach. Results: CINSARC and GI have strong, independent and validated prognostic values (p<0.0001). Comparing expression profiles of tumors
