The expression of myeloperoxidase (MPO) was studied in 100 cases of acute leukaemia (83 with acute myeloid leukaemia (AML) and 17 acute lymphoblastic leukaemia (ALL) by both a conventional cytochemical method and the immunocytochemical antiperoxidase (APAAP) technique using the monoclonal antibody MPO7. In each case the staining was evaluated by light microscopical examination (percentage of po...
The purpose of a classification is not only to group diseases with the same biological characteristics, but also to get insight into the pathogenesis and to define subgroups with different prognoses and different therapeutic approaches. In acute leukaemias the classification now most widely used is the French-American-British (FAB) classification as proposed in 1976, which was based on morpholo...
Blastomycosis-like pyoderma, a rare skin lesion which may clinically resemble true blastomycosis, is seen in immuno-compromised individuals. We report one such case in chronic myeloid leukaemia.
The most common acute hematological malignancy in adults is acute myeloid leukaemia (AML), accounting for more than 80% of cases in patients over 60 years of age [...].
BACKGROUND Activation of the Hedgehog signalling pathway contributes to cancer progression and the development of myeloid leukaemia stem cell therapeutic resistance. We aimed to identify the maximum tolerated dose (MTD) and the recommended phase 2 dose of the selective Hedgehog antagonist PF-04449913 in myeloid malignancies. METHODS We undertook an open-label, dose-finding, standard 3+3 desig...
A case of extramedullary myeloblastic transformation of chronic myeloid leukaemia is reported. This was characterised by an unusual clinical and haematological course and showed a unique cytogenetic pattern.
Chromosomal translocations are primary events in tumorigenesis. Those involving the mixed lineage leukaemia (MLL) gene are found in various guises and it is unclear whether MLL fusions can affect haematopoietic differentiation. We have used a model in which chromosomal translocations are generated in mice de novo by Cre-loxP-mediated recombination (translocator mice) to compare the functionally...
Cytogenetic abnormalities have long been recognized as the genetic basis of the occurrence of various malignancies. Specific cytogenetic abnormalities have shown to occur recurrently in particular subtypes of leukaemias and lymphomas. t(1;14) is an infrequently occurring recurrent chromosomal translocation that has been described in literature to be associated with haematological malignancies. ...
ASXL2 is frequently mutated in acute myeloid leukaemia patients with t(8;21). However, the roles of ASXL2 in normal haematopoiesis and the pathogenesis of myeloid malignancies remain unknown. Here we show that deletion of Asxl2 in mice leads to the development of myelodysplastic syndrome (MDS)-like disease. Asxl2-/- mice have an increased bone marrow (BM) long-term haematopoietic stem cells (HS...
Recently, whole genome sequencing approaches have pinpointed mutations in genes that were previously not associated with cancer. For Acute Myeloid Leukaemia (AML), and other myeloid disorders, these approaches revealed a high prevalence of mutations in genes encoding the chromosome cohesion complex, cohesin. Cohesin mutations represent a novel genetic pathway for AML, but how AML arises from th...
