Multiparametric flow cytometry is an alternative approach to the polymerase chain reaction method for evaluating minimal residual disease in treatment protocols for primary acute lymphoblastic leukemia. Given considerable differences between primary and relapsed acute lymphoblastic leukemia treatment regimens, flow cytometric assessment of minimal residual disease in relapsed leukemia requires ...
The relation between intrauterine growth and risk of childhood acute lymphoblastic leukemia was investigated in an Australian population-based case-control study that included 347 cases and 762 controls aged <15 years recruited from 2003 to 2006. Information on proportion of optimal birth weight, a measure of the appropriateness of fetal growth, was collected from mothers by questionnaire. Data...
We report two cases that presented with unexplained acute renal failure and hyperuricemia and were subsequently diagnosed with T-cell acute lymphoblastic leukemia. The patients improved with conservative therapy without the need for dialysis. Case 1 is the youngest case of acute lymphoblastic leukemia with spontaneous tumor lysis syndrome reported to date, and Case 2 presented with spontaneous ...
INTRODUCTION Osteoporosis in children is rare and usually secondary to an underlying disease process whose diagnosis may be difficult to detect. Etiological factors responsible for osteoporosis secondary to chronic illness include immobility, pubertal delay and other hormonal disturbances. Rarely, it can be a manifestation of acute lymphoblastic leukemia. Most of the reported bone fracture inci...
Tyrosine kinase inhibitors have profoundly modified the treatment and prognosis of chronic myeloid leukemia and Ph(+) acute lymphoblastic leukemia. A rapid and accurate detection of the BCR-ABL fusion protein is paramount today for an optimal management of Ph(+) acute lymphoblastic leukemia. We have utilized a recently described and commercialized immunoassay that identifies qualitatively the p...
background: central nervous system (cns) relapse in acute lymphoblastic leukemia was significantly decreased due to the use of new chemotherapyeutic agents, intrathecal chemotherapy and cranial irradiation. the purpose of this study was to compare the effectiveness of intrathecal (it) cns chemotherapy alone versus combination of it chemotherapy with cranial irradiation for prevention of cns rel...
background: bcl-2 is the most important anti-apoptotic regulator and bax is a pro-apoptotic protein. the status of these parameters or the ration of bcl-2 to bax is important in malignant cell fate as well as normal cells. methods: sixty-two all patients and 62 healthy sex-and age-matched controls were studied. after genotyping, the promoter region of the bax and bcl-2 genes by rflp-pcr method ...
Acute lymphoblastic leukemia in infants represents an aggressive malignancy associated with a high incidence (approx. 80%) of translocations involving the Mixed Lineage Leukemia (MLL) gene. Attempts to mimic Mixed Lineage Leukemia fusion driven leukemogenesis in mice raised the question whether these fusion proteins require secondary hits. RAS mutations are suggested as candidates. Earlier resu...
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...
