INTRODUCTION Acute lymphoblastic leukemia (ALL) is disease of lymphoid precursors and is the most common cancer. Diagnosis of ALL is made by evaluating morphology and flowcytometric Immunophenotyping (FCI)and is an important adjunct in diagnosis and determining treatment in ALL, with availability of extensive monoclonal antibodies in the recent years there is tremendous progress in the field of...

acute leukemias represent approximately 30% of malignant diseases in patients under the age of 15 years. leukemic infiltration of the central nervous system and testis are common events, particularly as sites of relapse in the third year after diagnosis. management of acute lymphoblastic leukemia is based on long-term chemotherapy, leading to a cure rate of approximately 80% of children and ado...

Although childhood acute lymphoblastic leukemia is the most common pediatric cancer, its etiology remains poorly understood. In an attempt to replicate the findings of 2 recent genome-wide association studies in a French-Canadian cohort, we confirmed the association of 5 SNPs [rs7073837 (P=4.2 x 10(-4)), rs10994982 (P=3.8 x 10(-4)), rs10740055 (P=1.6 x 10(-5)), rs10821936 (P=1.7 x 10(-7)) and r...

We report a case of bone marrow necrosis preceding infantile acute lymphoblastic leukaemia (ALL). Bone marrow necrosis is a rare antemortem event and has been known to be present in many conditions, notably in haematological malignancies like acute lymphoblastic leukaemia. This case was a 6-month-old Chinese boy who was referred to Hospital Universiti Kebangsaan Malaysia for further investigati...

In contrast to acute lymphoblastic leukemia in children, adult cases of this disease are associated with a very poor prognosis. In order to ascertain whether the frequencies and patterns of submicroscopic changes, identifiable with single nucleotide polymorphism array analysis, differ between childhood and adult acute lymphoblastic leukemia, we performed single nucleotide polymorphism array ana...

Infiltration of the central nervous system is a severe trait of T cell acute lymphoblastic leukemia. Inhibition of CXC chemokine receptor 4 significantly ameliorates T cell acute lymphoblastic leukemia in murine models of the disease; however, signaling by CXC chemokine receptor 4 is important in limiting the divagation of peripheral blood mononuclear cells out of the perivascular space into th...

Further improvement of outcome in childhood acute lymphoblastic leukemia could be achieved by identifying additional high-risk patients who may benefit from intensified treatment. We earlier identified PTPRC (CD45) gene expression as a potential new stratification marker and now analyzed the prognostic relevance of CD45 protein expression. CD45 was measured by flow cytometry in 1065 patients tr...

fms-like tyrosine kinase-3 is a receptor tyrosine kinase expressed by immature hematopoietic cells and is important for the normal development of stem cells and the immune system. mutations of fms-like tyrosine kinase-3 have been detected in about 30% of patients with acute myelogenous leukemia and a small number of patients with acute lymphoblastic leukemia. the fms-like tyrosine kinase-3 muta...

Acute myelofibrosis is characterized by pancytopenia of sudden onset, megakaryocytic hyperplasia, extensive bone marrow fibrosis, and the absence of organomegaly. Acute myelofibrosis in patients with acute lymphoblastic leukemia is extremely rare. We report a 4-year-old boy who was diagnosed as having acute massive myelofibrosis and acute lymphoblastic leukemia. Performing bone marrow aspiratio...

Acute lymphoblastic leukemia, acute myeloid leukemia, gingival enlargement. Abstract Most of the systemic diseases manifest signs and symptoms in oral cavity. Periodontal lesions are common in patients with acute leukemia throughout the course of the disease. Although many cases of gingival enlargement in patients with acute myeloid leukemia have been reported in literature, cases of gingival h...
