Of all cancers in childhood (by WHO definition: O-14 year age group), leukemias constitute one of the most important groups of tumors. Our understanding of the biologic features of the childhood leukemias has increased greatly over the past decade. The ability to discern cytogenetic and molecular differences among morphologically and immunologically similar populations of leukemic cells has hel...

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...

ubiquitin - proteasome system (ups), the major protein degradation pathway in the cells, typically degrades short - lived and damaged proteins and regulates growth and stress responses. this pathway is altered in various cancers, including acute lymphoblastic leukemia (all). all begins with a change in bone marrow cells and is the most common type of leukemia in children under 15 years. ube2q1 ...

introduction:  acute lymphoblastic leukemia (all) is the most common malignancy in children and the main form of childhood leukemia (75%). all different treatment options have a great impact on children weight and appetite. the improving prognosis for children with cancer refocuses attention to long-term outcomes with an emphasis on quality of life. more survival rate allows researchers to eval...

background evidence indicates rfc1 g80a polymorphism as a risk factor for a number of cancers. increasing studies have been conducted on the association of rfc1 g80a polymorphism with acute lymphoblastic leukemia (all) risk. however, the results were  controversial. the aim of the present study was to derive a more precise estimation of the relationship.  materials and method pubmed, embase, we...

Introduction: L-asparaginase and corticosteroids are widely used in the chemotherapy of acute lymphoblastic leukemia (ALL). This combination is known to cause several adverse effects one which hypertriglyceridemia. Although condition asymptomatic reversible it can lead serious complications.

We describe two patients with break point cluster region-Abelsen (BCR-ABL)-positive acute leukemia who had an isolated relapse in the central nervous system (CNS) while receiving a next-generation BCR-ABL inhibitor. The first had B-cell acute lymphoblastic leukemia which relapsed in the CNS while maintaining molecular remission in the bone marrow on nilotinib. The second patient had an isolated...

Bone marrow transplantation has become the accepted treatment for several hematologic disorders. We have done 3 autologous and 6 allogeneic bone marrow transplantations at Ramathibodi Hospital since July 1989 in patients with acute lymphoblastic leukemia, acute non-lymphocytic leukemia, chronic myeloid leukemia, non-Hodgkin's lymphoma and severe aplastic anemia. Only one patient with aplastic a...
