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 ...

NUDT15 genetic variants and 6-mercaptopurine intolerance in pediatric acute lymphoblastic leukemia: an updated review

unilateral malignant pleural effusion as an initial manifestation that leads to the diagnosis of an underlying acute lymphoblastic leukemia is a rare event. early and accurate diagnosis of this case is important for prompt and adequate therapy. we present the case of an18-year-old male who presented to the emergency department with severe respiratory distress. chest x-ray revealed a unilateral ...

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...
