The prognostic risk of acute myeloid leukemia (AML) is related with various chromosome abnormalities. In adult population, the presence of t (9; 22) (q34; q11) predicts a poor prognosis while t (15; 17) (q22; q21) usually indicates a good prognosis. Concurrence of both abnormalities is rare, with unknown prognosis. We ...
