The clinical significance of cytogenetic abnormalities in acute myeloid leukaemia.
During the last three decades it has become apparent that the majority of cases of acute myeloid leukaemia (AML) are characterized by at least one of a variety of recurrent chromosomal abnormalities. These changes have been found in many instances to correlate closely with distinct morphological features and clinical characteristics, the molecular basis of which is becoming increasingly underst...
متن کاملAcute leukaemia of ambiguous lineage--a diagnostic dilemma.
Acute leukaemia of ambiguous lineage (ALAL) is a rare form of leukaemia in which morphologic, cytochemical and immuno-phenotypic features of the proliferating blasts lack sufficient evidence to classify them as myeloid or lymphoid in origin or have characteristics of both myeloid and lymphoid cells. We report a 22-year-old man presenting with clinical features of an acute lymphoblastic leukaemi...
متن کاملCytogenetic Abnormalities in Myelodysplastic Syndromes: An Overview
Karyotype is one of the main constituents of the International Prognostic Scoring System (IPSS) and revised-IPSS that are the cornerstones for the prognostication of patients with myelodysplastic syndromes (MDS). Del(5q), -7/del(7q), +8 and -Y are among the most extensively studied cytogenetic abnormalities in MDS. The same applies for normal karyotype. There are hundreds of other rare cytogene...
متن کاملAcute biphenotypic leukaemia: immunophenotypic and cytogenetic analysis.
The incidence of acute biphenotypic leukaemia has ranged from less than 1% to almost 50% in various reports in the literature. This wide variability may be attributed to a number of reasons including lack of consistent diagnostic criteria, use of various panels of antibodies, and the failure to recognize the lack of lineage specificity of some of the antibodies used. The morphology, cytochemist...
