background: acute myeloid leukemia (aml) is known as one of the most common leukemia among adults. environmental and different genetic factors affect disease process, prognosis and treatment. among different genetic factors npm1, flt3, mll and baalc genes are the most effective on patient's survival rate. the aim of this study was to assess amount of baalc gene expression in aml patients, and i...

background: the treatment of acute promyelocy!c leukemia with all-trans-re!noic acid (atra) some!mes results in a syndrome characterized by fever, respiratory distress, weight gain, pleural or pericardial effusion, and pulmonary infiltrates. we report the major clinical and radiologic features of atra syndrome. materials and methods: in the past, occasional case reports and literature pertainin...

t cell acute lymphoblastic leukemia (all) is an invasive disease with a higher incidence in children and adolescents. in terms of immunophenotype, t-all is positive for cd2, cd7, cd34 and hla-dr, and the level of these markers is increased with increasing age. in addition, the myeloid markers (cd13, cd33) are sometimes expressed in t-all. in this study, we introduce a rare case of a 28-year-old...

a retrospective study was done on 130 aml patients treated in shariati and imam hospitals in tehran from 1991 to 1997 to investigate the value of three post-remission methods of treatment. all patients who were in complete remission (cr) (group i) had been treated with ara-c (300 mg/m2/day continuous infusion for 5 days) and daunorubicine (45 mg/m2/day for 3 days) as induction and early consoli...

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 ...

Promyelocyte Leukemia Zinc Finger (PLZF) is a Kruppel-like zinc finger gene previously identified in a unique case of acute promyelocytic leukemia (APL) as the counterpart of a reciprocal chromosomal translocation involving the retinoic acid receptor alpha gene (RAR alpha). PLZF is highly conserved throughout evolution from yeast to mammals. To elucidate its role, we isolated the murine PLZF ge...

Acute promyelocytic leukemia (APL) is characterized by a specific t(15;17) chromosomal translocation that yields the PML/RARA fusion gene. Clinically, besides chemotherapy, two drugs induce clinical remissions: retinoic acid (RA) and arsenic trioxide (As). Both agents directly target PML/RARA-mediated transcriptional repression and protein stability, inducing to various extent promyelocyte diff...

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.

acute leukemia is characterized by the accumulation of neoplastic cells in the bone marrow and peripheral blood. currently, chemotherapy and differentiating agents have been used for the treatment of leukemia. recently, plant extracts, either alone or in combination with chemo agents, have been proposed to be used for the treatment of cancers. the aim of the present research was to study the cy...

conclusions our findings indicated that mdm2 40-bp ins/del polymorphism was not associated with all in our iranian population. further studies with larger sample sizes and diverse ethnicities are required to verify our findings. background the human murine double minute 2 (mdm2), an oncoprotein, is the major negative regulator of p53. objectives the purpose of this study was to evaluate the imp...
