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...

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...

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-metabolizi...

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...

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...

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.
