Abstract

Desmoplastic small round cell tumor (DSRCT) is a poorly understood neoplasm with distinctive clinical, histologic and immunophenotypic features. It is associated with a novel, specific chromosomal abnormality, t(11;22)(p13;q12) that fuses EWS with WT1 leading to production of a chimeric protein with transcriptional regulatory activity. This chimeric transcription factor has unique DNA-binding properties and regulates expression of specific target genes. Several of these have been identified and their biological role characterized. The dysregulated expression of EWS-WT1 targets contribute to the malignant phenotype of DSRCT and provide valuable insight regarding the molecular mechanisms underlying the development and progression of this distinct translocation associated tumor.
