T-cell acute lymphoblastic leukemia arises from the leukemic transformation of developing thymocytes and results from cooperative genetic lesions. Inactivation of the PHF6 gene is frequently observed in T-cell acute lymphoblastic leukemia, suggesting an important tumor suppressive role for PHF6 in the pathobiology of this leukemia. Although the precise function of PHF6 is still unknown, this ge...

Advances in the molecular characterization of leukemic cells have greatly improved the precision of diagnosis and treatment assignment as well as the monitoring of residual disease in both acute lymphoblastic leukemia and acute myeloid leukemia. Currently, specific genetic rearrangements can be identified in as many as 50% of children with either acute lymphoblastic leukemia or acute myeloid le...

The class I receptor tyrosine kinase (RTK) HER2 is an oncoprotein that is frequently involved in the pathogenesis of tumors of epithelial origin. Here we report mRNA expression in peripheral blood and bone marrow cells from healthy donors in hematopoietic cell lines and leukemic blasts from patients with acute lymphoblastic leukemia (ALL), acute myeloblastic leukemia (AML), chronic lymphoblasti...

Effect of graft source on unrelated donor haemopoietic stem-cell trans-plantation in adults with acute leukaemia: a retrospective analysis. al. Unrelated transplantation for poor-prognosis adult acute lym-phoblastic leukemia: long-term outcome analysis and study of the impact of hematopoietic graft source. R, et al. Favorable outcome of unrelated cord blood transplantation for Philadelphia chro...

Background: Acute leukemia is one of the most common types of childhood malignancies and one fourth of malignancies in this age group is acute leukemia. Acute leukemia may be myeloid or lymphoid. Acute lymphoblastic leukemia is characterized with abnormal proliferation of lymphoid cells and symptoms related to this are acute and if disease is not treated appropriately, it progresses rapidly and...

Leukemia is the most common malignancy in children which leads to immunosuppression and predisposes patients to opportunistic infections. We report a 12-year-old girl with acute lymphoblastic leukemia (ALL) who developed simultaneous infection with pneumocystis Jirovecii pneumonia and aspergillosis in the induction phase of chemotherapy. The patient developed pulmonary cavitation and pneumothor...

UNLABELLED Acute lymphoblastic leukemia (ALL) constitute a family of genetically heterogeneous lymphoid neoplasms derived from B- and T-lymphoid progenitors. ALL affects both children and adults. Diagnosis is based on morphologic, immunophenotypic, and genetic features that allow differentiation from normal progenitors and other hematopoietic and nonhematopoietic neoplasms. The aim of this stud...

C hronic lymphocytic leukemia (CLL) is a frequent CD5 + B-cell neoplasia that involves peripheral blood, bone marrow, lymph nodes and other lym-phoid tissues. The median age of patients at diagnosis of CLL is around 70 years old and the prognosis is extremely variable. In spite of some advances in its therapy, CLL continues to be incurable. Due to this fact, and to the prognos-tic heterogeneity...

Malignant lymphocyte populations in peripheral blood of patients with B-cell chronic lymphocytic leukemia, leukemic variant of B-cell non-Hodgkin's lymphoma, and hairy cell leukemia can be characterized by the use of a monoclonal murine antibody (anti-Y 29/55) which is directed against a cell membrane component normally confined to the sessile nonrecirculating cells of the B-lymphocyte populati...

Acute lymphoblastic leukemia (ALL) is the most common malignancy in children. Despite remarkable improvements treatment of pediatric acute over last years, relapse still carries a poor prognosis with considerable morbidity and mortality. New immunotherapeutic approaches will change way we treated our patients results had. Blinatumomab bispecific T-cell-engaging antibody indicated for relapsed/r...
