摘要: The detection of hyperdiploidy (clones with >46 chromosomes) in the bone marrow patients acute lymphoblastic leukaemia (ALL) is important because prognostic impact this finding. high hyperdiploid (HeH) subgroup 51-68 chromosomes associated best outcome, followed by low (HeL) 47-50 and triploid/tetraploid (TT) >68 chromosomes, which do less well. We present a strategy for use fluorescence situ hybridization (FISH) chromosome-specific probes to detect interphase cells assign cases ploidy subgroup. By using model population 252 cases, it was seen that ten (X, 4, 6, 8, 10, 14, 16, 18, 20, 21) used particular combinations applied step-wise manner enabled 94% gave an accurate prediction 96% these cases. classification each case required four six over two or three steps. Confirmation will achieve level other populations demonstrated 250 published karyotypes. This has application detecting missing hidden among failed normal cytogenetics.
