A-42 MOLECULAR BIOLOGY AND KARYOTYHNG ANALYSES USING FINE NEEDLE ASPIRATION MATERIAL AS A DIAGNOSTIC METHOD IN PPNET-EWING SARCOMA: INSTITUT CURIE EXPERIENCE

摘要

Between 1992 and 2005,42 patients with Ewing sarcoma (ES) were initially diagnosed cytologically, then biopsied at our Institute. Patient age ranged from 0 to 38 years (median IS). Fine needle aspiration (FNA) specimens were smeared for cytodiagnosis and collected in culture medium supplemented with EDTA, counted and sent for ancillary techniques, that is, molecular biology and karyotyping analyses.
