Diagnostic utility of FLI‐1 monoclonal antibody and dual‐colour, break‐apart probe fluorescence <i>in situ</i> (FISH) analysis in Ewing's sarcoma/primitive neuroectodermal tumour (EWS/PNET). A comparative study with CD99 and FLI‐1 polyclonal antibodies

Abstract excerpt

AIMS: To compare the sensitivity and specificity of the recently commercially available FLI-1 monoclonal (FLI-1m) antibody with the currently used antibodies [CD99 and FLI-1 polyclonal (FLI-1p)] in the diagnosis of Ewing's sarcoma/primitive neuroectodermal tumour (EWS/PNET) and to determine the diagnostic value of the EWSR1 (22q12) dual-colour, break-apart rearrangement probe fluorescence in situ hybridization...
