The clinical heterogeneity of round cell sarcomas with EWSR1 / FUS gene fusions: Impact of gene fusion type on clinical features and outcome

Abstract excerpt

The genetic hallmark of classic Ewing sarcoma is a recurrent fusion between EWSR1 and FUS gene with a member of the ETS transcription factor family. In contrast, tumors with non-ETS gene partners have been designated until recently "Ewing-like sarcoma," as a provisional molecular entity, as their clinical and pathologic features were still evolving. However, this group was reclassified as "round cell sarcoma with...
