Comparison between results of Urovysion FISH (in two selected tumoral areas of the same FFPE section) and array-CGH.

LOSS: number of signals: 0 and 1; DISOMY: number of signals even (2, 4, 6, 8, 10, 12); GAIN number of signals odd (3, 5, 7, 9, 11).Gray: CNA detected by both techniques and by both tumoral FISH areas.**: CNA detected by both techniques but by only one tumoral FISH area; or by both tumoral FISH area but not by array-CGH.*: CNA detected by only array-CGH, or by only one tumoral FISH area.Positive FISH if at least 25% of cells detected the CNA.Na: not available.
