The molecular pathogenesis of Ewing sarcoma

Ewing sarcoma family tumors (ESFT) are a group of aggressive solid bone and soft tissue malignancies of children and young adults characterized by specific chromosomal translocations that give rise to EWS-ETS aberrant transcription factors. Identification of EWS-ETS target genes and their role in tumor signaling networks together with the unravelling of the cell of origin will facilitate the translation into new treatment modalities for these neoplasms.
