Background: Previous studies have pointed to the major role of viruses in pathogenesis cancers, especially lymphoproliferative cancers. Objectives: The current study investigated relationship between recent Human Herpesvirus Type 6 (HHV6) infection and childhood leukemia-lymphoma syndrome. Methods: From January 2011 December 2012, we entered every new case acute lymphoblastic leukemia, non-Hodg...
Oncoprotein E2a/Pbx1 is produced by the t(1;19) chromosomal translocation of human pre-B acute lymphoblastic leukemia. E2a/Pbx1 blocks differentiation of primary myeloid progenitors but, paradoxically, induces apoptosis in established pre-B-cell lines, and no transforming function of E2a/Pbx1 has been reported in cultured lymphoid progenitors. Here, we demonstrate that E2a/Pbx1 induces immortal...
Acute Lymphoblastic Leukemia (ALL) is a cancer that infects the blood cells causing development of lymphocytes in large numbers. Diagnostic tests are costly and very time-consuming. It important to diagnose ALL using Peripheral Blood Smear (PBS) images, especially initial screening cases. Several issues affect examination process such as diagnostic error, symptoms, nonspecific nature signs ALL....
Leukemia incidence in children has increased worldwide in recent decades, particularly due to the rise in acute lymphoblastic leukemia. Studies have associated exposure to non-ionizing radiation generated by low frequency magnetic fields with childhood leukemia. The current article reviews the case-control studies published on this subject. Of 152 articles tracked in different databases, ten st...
Recurrent deletions of the long arm of chromosome 5 were detected in 23/200 cases of T-cell acute lymphoblastic leukemia. Genomic studies identified two types of deletions: interstitial and terminal. Interstitial 5q deletions, found in five cases, were present in both adults and children with a female predominance (chi-square, P=0.012). Interestingly, these cases resembled immature/early T-cell...
Background and Aim: Acute Lymphoblastic Leukemia is the most common cancer in children and is one of the main causes of their mortality. In this study, we examined the expression of long noncoding RNA CCDC26 gene and its downstream C-Kit gene in acute lymphocytic Leukemia cell line. Materials and Methods: This is an experimental study. In this study, the acute Lymphoblastic Leukemia cell lines...
BACKGROUND The prognostic value of the ectopic activation of TLX3 gene expression, a major oncogenetic event associated with pediatric T-cell acute lymphoblastic leukemia, is controversial. Likewise, the frequency and the prognostic significance in pediatric T-cell acute lymphoblastic leukemia of the newly characterized NUP214-ABL1 fusion transcript is not yet clear. DESIGN AND METHODS Two hu...
Donor-derived malignancies after allogeneic hematopoietic stem cell transplantation and after solid organ transplantation are considered as rare diseases. We have prospectively searched for donor cell leukemia in a 12-year period, in a single institution, in a group of 106 consecutive patients allografted because of leukemia. We have identified seven cases of donor cell leukemia; six were allog...
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...
