Acute myeloid leukemia (AML) with t(8;21)(q22;q22) generating the AML1/ETO fusion gene on 8q22 is a distinct type of AML t(8;21) category (WHO)/AML-M2 (FAB), generally associated with a favourable prognosis. Variant additional chromosomal abnormalities are frequently reported. We report three adult cases of this category with unusual karyotype. Bone marrow cytogenetics of case no. 1: 45,X,-Y, t...

The t(8;21)(q22;q22) results in the formation of RUNX1/ RUNX1T1 (alias AML1/ETO) and RUNX1T1/RUNX1 fusion genes on der(8)t(8;21)(q22;q22) and der(21)t(8;21)(q22;q 22), respectively. An 18-year-old woman was diagnosed as having acute myeloid leukemia (AML) M2, as her bone marrow was infiltrated with 42.2% myeloblasts. Auer rods were found in myeloblasts and metamyelocytes (Picture A, B, arrows)....

A 62-year-old female was diagnosed with acute myeloid leukemia (AML) t(16;21)(p11;q22). She achieved complete hematological remission after induction therapy and underwent umbilical cord blood stem cell transplantation (CBT). At 150 days the CBT, a bone marrow examination revealed relapse. We treated patient venetoclax plus azacitidine as salvage therapy. After five cycles of therapy, died due ...

A a Abstract. Variant forms of the classic translocation t(8;21) are uncommon and account approximately 3% of all t(8;21)(q22;q22) in acute myeloid leukemia (AML) patients. These forms involve chromosomes 8, 21, and other chromosomes. Here we report a Tunisian patient with a complex rearrangement t(21;8;1)(q22;q22;q32) revealed by conventional chromosomal study at diagnosis. Fluorescence in sit...

Fluroscent in situ hybridization analysis indicated presence of t(12;21)(p13;q22) translocation and near-tetraploidy in a case who 11-year-old boy and diagnosed with B precursor acute lymphoblastic leukemia (ALL). Although, some studies suggest good prognostic effect of translocation t(12;21) (p13;q22), there were very little data regarding the prognostic effect of Near-tetraploidy. Here we dis...

Many AML-associated chromosomal abnormalities, such as t(8;21), t(15;17), inv(16), t(9;11), t(9;22) and t(6;9) are well known. The chromosomal aberration of t(16;21)(p11;q22) in AML is rare and it is known to be associated with poor prognosis, young age (median age, 22 yr), and involvement of various subtypes of the French-American-British classification. We report here 2 AML patients with t(16...
