A recently characterized group of undifferentiated small round cell sarcomas harbours fusions of the genes m>CICm> and m>DUX4m>. Studies report a distinctive gene expression profile for these sarcomas, including expression of E26 transformation-specific (ETS) family proto-oncogenic transcription factors m>ETV1, ETV4m> and m>ETV5m>. To test the utility of an ancillary diagnostic technique for these tumours, we evaluated chromogenic RNA m>in-situm> hybridization assays for m>ETV1m>,m> ETV4m> and m>ETV5m> as diagnostic adjuncts for this emerging group of highly malignant sarcomas.
