acute lymphoblastic leukemia (all) is a malignant disorder of lymphoid precursor cells, which could be classified according to morphological and cytochemical methods as well as immunophenotyping. twenty patients with all, who had been referred to the children's medical center hospital, during the year 2007, were enrolled in this study in order to evaluate the morphologic and immunophenotypic pr...

maintenance treatment for patients with acute myeloid leukemia (aml) in remission has recently been controversially discussed and even abandoned by several groups. an analysis of 16 published multicenter trials, however, revealed the highest probabilities of relapse free survival (rfs) in the range of 35-42 % at 4-5 years only in patients assigned to maintenance treatment when adult age and int...

Midface bones are an unusual site for primary presentation and relapse in acute lymphoblastic leukemia. Herein, we describe a case of acute pre B cell lymphoblastic leukemia with leukemic infiltration of maxilla and bone marrow involvement. At the time of relapse, the patient presented again with maxilla involvement and the phenotype changed to biphenotypic lymphoblastic leukemia. Our case sug...

the appendix is an unusual site for extramedulary relapse in acute leukemia. the present case report describes two cases of late course acute lymphoblastic leukemia presented with leukemic infiltration of the appendix and complete remission of bone marrow. the signs and symptoms of the cases suggest that leukemic involvement of the appendix should be considered in the differential diagnosis of ...

acute lymphoblastic leukemia (all) is one of the most common cancers among children. although there have been tremendous treatments, none of them have led to a precise cure. the use of herbal medicines which are safe and non-toxic have been demonstrated in this study. curcumin is a polyphenol, hydrophobic product that is derived from turmeric plant. curcumin has anti-toxic, anti-bacterial, anti...

previous studies have demonstrated some significant differences in hla allele frequencies in leukemic patients and normal subjects. we have analyzed hla class ii alleles and haplotypes in 60 iranian patients with acute myelogenous leukemia (aml) and 180 unrelated normal subjects. blood samples were collected after obtaining informed consents. from the patients and control dna extraction and hla...

background: acute leukemias are characterized by neoplastic proliferation of hematopoietic stem cells and accumulation of blasts and immature cells in the bone marrow. we applied a selective panel of immunohistochemical markers on bone marrow trephine tissue sections and observed their utility in diagnosis and typing of acute leukemia. materials and methods: the study was done at psg institute ...

nucleostemin (ns), a stem cell-abundant nucleolar protein, is critical for maintaining the self-renewal and proliferative properties of normal and cancerous stem cells. recent data suggests that ns signaling is important for proliferation of t-cells and leukemia cells. this study was conducted to verify the role of ns in pathogenesis and treatment of t-cell acute lymphocytic leukemia (t-all). o...

abnormalities of the thyroid gland are among the most frequent endocrine complications observed in childhood cancer survivors. we report an 11 years old girl who developed central hypothyroidism and acth deficiency during the chemotherapy for cns relapse of acute lymphoblastic leukemia before receiving radiotherapy. keywords: thyroid gland, hypothyroidism, chemotherapy, acute lymphoblastic leuk...
