BACKGROUND Imatinib mesylate has shown promising results in chronic myeloid leukemia (CML) in all phases. This drug is an effective treatment for patients with CML in chronic phase as it induces hematological remission in nearly all patients and cytogenetic responses in many. The bone marrow changes produced by this drug are different from the treatment modalities used earlier in CML. MATERIA...

Cytogenetic, biomolecular, and clinicopathologic features were retrospectively studied in 34 adult patients with acute myelogenous leukemia expressing one or more of the following lymphoid-associated markers (LMs): CD7, CD2, CD10, CD19, CD22, TdT. Six patients showed 11q23 rearrangements (group I); three patients had the classic Ph chromosome (group II); 15 patients had aberrations of the myelo...

Sustained imatinib treatment in chronic myeloid leukemia patients can result in complete molecular response allowing discontinuation without relapse. We set out to evaluate the frequency of complete molecular response in imatinib de novo chronic phase chronic myeloid leukemia patients, to identify base-line and under-treatment predictive factors of complete molecular response in patients achiev...

PURPOSE Cytogenetic analysis of a pleomorphic adenoma (PA) arising in the major salivary glands, in particular the parotid, is well documented, with chromosome 8 being the most commonly involved aberration, mainly in t(3;8). However, cytogenetic studies of PA in the minor salivary glands (MSGs) are rare and, to the authors' knowledge, only 3 reports have been published. The authors investigated...

MOTIVATION Staining the human metaphase chromosomes reveals characteristic banding patterns known as cytogenetic bands or cytobands. Using technologies based on metaphase chromosomes, researchers have accumulated much knowledge about the correlations between human diseases and specific cytoband aberrations, indicating the presence of disease-associated genes in those bands. With the progress of...

Identification of cytogenetic abnormalities is an important clue for the elucidation of carcinogenesis. However, the cytogenetic and clinical significance of adult T-cell leukemia/lymphoma (ATLL) is still unclear. To address this point, cytogenetic findings in 50 cases of ATLL were correlated with clinical characteristics. Karyotypes showed a high degree of diversity and complexity. Aneuploidy ...

BACKGROUND Cytogenetic abnormalities have important implications in diagnosis and prognosis of acute leukemia and are now considered an important part of the diagnostic workup at presentation. Karyotype, if known at the time of diagnosis, guides physicians to plan appropriate management strategies for their patients. AIM AND OBJECTIVES To determine the cytogenetic profile of acute lymphoblast...

Myelodysplastic syndrome (MDS) is a group of clonal hematopoietic diseases characterized by cytopenia, dysplasia and increased risk of development to acute myeloid leukemia (AML). Unfavorable cytogenetic changes such as complex karyotypes or chromosome 7 anomalies are predictive of the progression to AML and poor prognosis. Central diabetes insipidus (CDI) is the result of a deficiency of argin...

Chronic myelomonocytic leukemia (CMML) is a myeloid neoplasm characterized by both myeloproliferative and myelodysplastic features in addition to persistent peripheral blood monocytosis (>1×109/L) that is required for the diagnosis. Clonal cytogenetic abnormalities are identified in only 20%-30% of CMML patients and it can be diagnostically challenging to exclude reactive monocytosis in some ca...

BACKGROUND The accurate identification of cytogenetic abnormalities in multiple myeloma (MM) has become more important over recent years for the development of new diagnostic and prognostic markers. In this study, we retrospectively analyzed the cytogenetic aberrations in MM cases as an initial assessment in a single institute. METHODS We reviewed the cytogenetic results from 222 patients who...
