conclusions it was demonstrated that the presence of del6q21 in b-cll patients indicates poor prognosis and on the contrary, presence of del17p13 points at the good prognostic value of the disease. results deletion of 17p13 was found in 11 (16.6%) and deletion 6q21 was present in 5 (7.5%). statistical analyses were performed to investigate the correlation of these molecular-cytogenetic findings...

BACKGROUND The difference in prognosis of adult and childhood acute lymphoblastic leukemia (ALL) can be attributed largely to variation in cytogenetic abnormalities with age groups. Cytogenetic analysis in acute leukemia is now routinely used to assist patient management, particularly in terms of diagnosis, disease monitoring, prognosis and risk stratification. Knowing about cytogenetic profile...

Background & Objective: Soft tissue sarcomas (STS) constitute an uncommon and heterogeneous group of tumors of mesenchymal origin and various cytogenetic abnormalities ranging from distinct genomic rearrangements, such as chromosomal translocations and amplifications, to more intricate rearrangements involving multiple chromosomes. Fluorescence in situ...

Fourteen patients with cytogenetic relapse of chronic myeloid leukemia (CML) after transplantation with unmanipulated bone marrow were treated with alpha-2a-interferon. There were eight men and six women, median age, 33 years. Twelve patients received marrow from a related allogeneic donor and two received marrow from a syngeneic donor. The median percentage of Ph-positive metaphases at the tim...

PURPOSE The purpose of our investigation was to evaluate the response and minimal residual disease by quantitative competitive PCR (QC-PCR) studies in patients with chronic myeloid leukemia (CML) treated with imatinib mesylate. EXPERIMENTAL DESIGN One hundred eighty patients with Philadelphia chromosome (Ph)-positive chronic-phase CML after IFN-alpha failure, treated with imatinib mesylate, h...

Cytogenetic studies in clonal plasma cell disorders have mainly been done in whole bone marrow or CD138(+) microbead-enriched plasma cells and suggest that recurrent immunoglobulin heavy chain translocations - e.g. t(4;14) -are primary oncogenetic events. The aim of this study was to determine cytogenetic patterns of highly purified aberrant plasma cells (median purity ≥ 98%) in different clona...

Cytogenetic abnormalities are important clinical parameters in various types of cancer, including multiple myeloma. We developed a model to predict cytogenetic abnormalities in patients with multiple myeloma using gene expression profiling and validated it by different cytogenetic techniques. The model has an accuracy rate up to 0.89. These results provide proof of concept for the hypothesis th...

The aims of this study were (1) to evaluate the effect of intermediate (cyclophosphamide alone) or intensive (mitoxantrone, cytosine arabinoside, cyclophosphamide) priming on the cytogenetic response in mobilized bone marrow (BM) or peripheral blood (PB) progenitors in patients with chronic myelogenous leukemia (CML), (2) to determine the incidence of cytogenetic remissions after mobilized prog...

Introduction Turner syndrome characterized by total/partial and/or homogeneous/mosaic X chromosome monosomy is associated with various physical health concerns, including facial dysmorphism, short stature, infertility, and other organ defects such as heart, kidney, bone, skin, … well variable degrees of cognitive impairments. Besides, social skills, communication relationships are usually disor...
