BACKGROUND Interest has recently been paid to adolescents and young adults with acute lymphoblastic leukemia, particularly because all reports so far published indicate that these patients have a better outcome when treated with pediatric rather than adult therapeutic protocols. There are different biological subtypes of acute lymphoblastic leukemia with distinct features and prognoses; the dis...
Deletions and mutations affecting lymphoid transcription factor IKZF1 (IKAROS) are associated with an increased relapse risk and poor outcome in B-cell precursor acute lymphoblastic leukemia. However, additional genetic events may either enhance or negate the effects of IKZF1 deletions on prognosis. In a large discovery cohort of 533 childhood B-cell precursor acute lymphoblastic leukemia patie...
Diffusion tensor imaging and neurocognition in survivors of childhood acute lymphoblastic leukaemia.
Survivors of childhood acute lymphoblastic leukaemia are at risk for neurocognitive impairment, though little information is available on its association with brain integrity, particularly for survivors treated without cranial radiation therapy. This study compares neurocognitive function and brain morphology in long-term adult survivors of childhood acute lymphoblastic leukaemia treated with c...
BACKGROUND The hierarchical organization of hematopoiesis with unidirectional lineage determination has become a questionable tenet in view of the experimental evidence of reprogramming and transdifferentiation of lineage-determined cells. Clinical examples of hematopoietic lineage plasticity are rare. Here we report on a patient who presented with an acute B-lymphoblastic leukemia and develope...
background: acute lymphoblastic leukemia is a lymphoid malignancy, resulting from autonomous proliferation of monoclonal abnormal stem cell. the aim of this study was to evaluate the response rate and prognostic factor of adult patients suffering from acute lymphoblastic leukemia, who were treated with chemotherapy in south east of iran and demographic methods were used for this study. method...
back ground: vincristine (vcr), is a chemotherapy drug, useful in the treatment of leukemia, lymphoma and solid tumor and it is a potent neurotoxin and sensory neuropathy drug which a common behavioral toxicity of this drug. neuropathy is common squeal of intensive chemotherapy protocols that contain vincristine and corticosteroids. materials and methods: this study was a retrospective and desc...
acute lymphoblastic leukemia (all) is the most prevalent hematological malignant tumor during childhood. unilateral infiltration into the gums is less prevalent and more often observed in the aml type. a 12-year-old girl with symptoms of pain and swelling in the buccal vestibule and also at the posterior part of the right palate of the maxilla was referred to a private dental office. the patien...
background: the frequency of the multi-drug resistance 1 (mdr1) gene c3435t polymorphism differs in various ethnical populations such as asian, african, and caucasians populations. a silent c3435t polymorphism in exon 26 of mdr1 has been reported to be associated with a decreased expression of p-gp in tt genotypes carriers compared with cc genotypes carriers. materials and methods: to evaluate ...
background: the aim of this study was to detect the prognostic significance of survivin level and the expression of total p53 in acute lymphoblastic leukemia (all) and its correlation to patients' outcome. methods: sixty two children newly diagnosed with acute lymphoblastic leukemia were treated with chemotherapy and followed up for 2 years or until death. twenty apparently healthy volunteers w...
in many acute leukemias, normal differentiation does not occur. however, in many cell lines derived from hematologic malignancies, differentiation or apoptosis can be induced by variety of agents. despite advances in the treatment of acute lymphoblastic leukemia (all), in most patients long-term survival rates remain unsatisfactory, especially in t-cell derived all. thus we studied the anti-can...
