AIMS AND BACKGROUND The SET gene is a target of chromosomal translocations in acute leukemia and encodes a widely expressed multifunctional phosphoprotein. It has been shown that SET is upregulated in BCR-ABL1-positive cell lines, patient-derived chronic myeloid leukemia CD34-positive cells, and some solid tumors. METHODS AND STUDY DESIGN We determined the expression level of SET in 59 pediat...

recent studies have provided evidence that common genetic variations could account for a proportion of leukemia in adult or children. to evaluate the contribution of candidate gene association studies to the understanding of genetic susceptibility to acute lymphoblastic leukemia we conducted a systematic review from published studies. the polymorphisms of genes encoding carcinogen-metabolizing ...

Blast cells were obtained from 17 patients with acute undifferentiated leukemia and 13 patients with chronic myelogenous leukemia in blast crisis. The blasts were tested with anti-i serum in cytotoxicity tests and with antisera to myeloblastic leukemia-associated antigens in immunofluorescence tests. The terminal deoxynucleotidyl transferase (TDT) content of the blasts was also measured. Lympho...

background : we conducted the present study to investigate the frequency of prothrombin g20210a mutation among acute lymphoblastic leukemia patients and healthy individuals from western iran and to detect the possible association between this mutation and the risk of acute lymphoblastic leukemia in our population. methods : the studied groups consisted of 92 children with acute lymphoblastic le...

The class I receptor tyrosine kinase (RTK) HER2 is an oncoprotein that is frequently involved in the pathogenesis of tumors of epithelial origin. Here we report mRNA expression in peripheral blood and bone marrow cells from healthy donors in hematopoietic cell lines and leukemic blasts from patients with acute lymphoblastic leukemia (ALL), acute myeloblastic leukemia (AML), chronic lymphoblasti...

Background: Coexistence of Chronic lymphocytic lymphoma (CLL) to Acute lymphoblastic leukemia is extremely rare with only a few reported cases [1-5]. Chronic lymphocytic leukemia is a neoplasm of small monomorphic round to irregularly shaped lymphocytes of B-cell lineage. Adverse prognostic factors in CLL include flow cytometric expression of ZAP-70 and CD38 which are surrogate markers for the ...

neuroblastoma is the most common extracranial solid tumor in children. the co- occurrence of neuroblastoma and acute lymphoblastic leukemia is rare. we report a rare case of advanced-stage neuroblastoma in a 3.5-year-old girl that was accompanied by acute lymphoblastic leukemia following treatment. her leukemia may have been due to chemotherapy (secondary leukemia) or may have been de novo.

Acute leukemia which is the most common cancer in children is a heterogeneous group of clonal malignancies. The conversion of the leukemic cell lineage during the course of the disease or later is termed lineage switch. It has been rarely reported in the literature. In leukemia lineage switch, conversions from lymphoblastic leukemia to myeloid leukemia or vice versa are reported. Herein, we rep...

Actual BCR-ABL kinase inhibition in vivo as determined by phospho-CRKL (pCRKL) monitoring has been recognized as a prognostic parameter in patients with chronic myelogenous leukemia treated with imatinib. We report a biomarker sub-study of the international phase I clinical trial of nilotinib (AMN107) using the established pCRKL assay in imatinib-resistant chronic myeloid leukemia or Ph+ acute ...
