I N CHRONIC GRANULOCYTIC LEUKEMIA neurologic manifestations due to leukemic infiltration of the central nervous system occur uncommonly.’ In acute lymphoblastic leukemia, on the other hand, diffuse leukemic infiltration of the lepto-meninges is frequent and must be differentiated from neurologic involvement due to infection, hemorrhage, or drug toxicity.2 \Vhen acute myeloblastic transformation...
Introduction: Acute Leukemia with Mixed Lineage phenotype (MLL) is leukemia that consists of cells characterized by mixed lineage markers, both from myeloid and lymphoid cells. The incidence this only 2-5% all acute leukemias considered to have a poor prognosis.Case Presentation: A seven-year-old girl was diagnosed MLL. results immunophenotyping showed two blast populations the expressions CD33...
Acute lymphoblastic leukemia is the major pediatric cancer in developed countries. To date most association studies of acute lymphoblastic leukemia have been based on the candidate gene approach and have evaluated a restricted number of polymorphisms. Such studies have served to highlight difficulties in conducting statistically and methodologically rigorous investigations into acute lymphoblas...
Several methods to model human Ph+ leukemia in laboratory mice are available, including propagation of BCR/ABL-expressing cells in mice, xenotransplantation of primary Ph+ leukemia cells into immunodeficient mice, BCR/ABL transgenic mice, and BCR/ABL retroviral bone marrow transduction and transplantation. Recent studies in these different model systems have yielded important advances in our kn...
calcium metabolic disorders, such as hypercalcemia is a potentially life-threatening disorder especially when coupled with an already compromised condition. the aim of this study was to determine the prevalence of metabolic calcium disorders in childhood cancers of patients admitted to the pediatric ward of vali-asr hospital from the year 2001-2008. the study was carried out by reviewing hospit...
White blood cells from 22 patients with leukemia and lymphoma were studied for the presence of terminal deoxynucleotidyl transferase with a peroxidase-antiperoxidase method. The enzyme was detected in leukemic cells of 5 patients with acute lymphoblastic leukemia and 1 patient with chronic myelogenous leukemia, whereas 16 patients with different forms of leukemia or lymphoma were negative for t...
Acute lymphoblastic leukemia is the most common malignancy in children with a 5-year survival rate, accounting for 80% of cases. Melanoma is rare in children and has been reported as a sporadically occurring secondary malignant neoplasm in children with acute lymphoblastic leukemia. This study presented a 10-year-old Iranian child with pre-B-cell acute lymphoblastic leukemia that was diagnosed ...
Two children presented with Ph1-positive leukemia, confirmed by Giemsa banding as 22q-. One child showed an initial presentation characteristic of acute lymphoblastic leukemia, followed by development of chronic myelocytic leukemia 2 yr later. A second child presented in blast crisis. Both patients showed blast cells possessing both lymphoid and myeloid characteristics, as demonstrated by histo...
Imatinib is a selective tyrosine kinase inhibitor which acts on breakpoint cluster region-Abelson fusion gene (BCR-ABL) positive leukemia including all phases of chronic myeloid leukemia and acute lymphoblastic leukemia. It may induce rapid apoptosis and subsequent tumor lysis syndrome. Only 3 cases of imatinib-induced tumor lysis syndrome have been reported. We herein described an additional p...
For many years, methotrexate has been used in the treatment of certain chronic medical disorders e.g. rheumatoid arthritis and psoriasis as well as a number of malignant disorders e.g. acute lymphoblastic leukemia, certain types of lymphoma and breast carcinoma. Its use has been associated with various systemic toxicities and complications. The association between methotrexate therapy and the d...
