We studied the nature of blast cells in 41 patients with acute leukemia following a previous primary myelodysplastic syndrome (MDS) by a combined multiparameter analysis including morphologic, immunophenotypic, and molecular genetic (Igs, T-cell receptor (TCR)-beta, -gamma, and -delta and the major breakpoint cluster region [M-bcr]) investigations. In addition, the clinical and hematologic char...
In the August 1,1991 issue ofBlood, San Miguel et all published a report of 41 acute leukemia cases secondary to a myelodysplastic syndrome (MDS). Two were classified as M6 French-AmericanBritish (FAB) subtype on morphologic aspect, but the only erythroid immunologic marker tested, ie, glycophorin A, was negative. This characteristic, owing to the fact that glycophorin A is a relatively mature ...
BACKGROUND AND OBJECTIVES The biological characteristics and the prognostic significance of the internal tandem duplication of the FLT3 (FLT3/ITD) were investigated in a series of de novo acute myeloid leukemia (AML) patients. One hundred and fifty-six adult patients with AML were included in the study. FLT3/ITD was detected in 41 (26%) patients (FLT3/ITD(+)). DESIGN AND METHODS The main diff...
To determine the biologic significance of the structural rearrangements of the long arm of chromosome 6(6q) in acute lymphoblastic leukemia (ALL) at diagnosis, we studied 412 consecutive children whose leukemic cell chromosomes had been completely banded and identified 45 (11%) children with this abnormality. The 45 cases were divided into del(6q) only (n = 11), del(6q) and numerical abnormalit...
