Characterization of ABL1 expression in adult T-cell acute lymphoblastic leukemia by oligonucleotide array analysis

Hematopathology / ADULT T-CELL ACUTE LYMPHOBLASTIC LEUKEMIA

We analyzed the clinicopathologic and molecular findings in 26 adults (age 16-72 years) with T-cell acute lymphoblastic leukemia (T-ALL) and observed features that correlated with age. Patients older than 60 years (n = 5) had a low frequency of hepatosplenomegaly (0 [0%]), anterior mediastinal mass (1 [20%]), and lymphadenopathy (2 [40%]), and completely responded to chemotherapy (4 of 4). The ...

Prolonged Vincristine Toxicity Induced by Concurrent Posaconazole in a Child with T-cell Acute Lymphoblastic Leukemia

Diversity of T-cell receptor Gene Rearrangements in South Indian Patients with Common Acute Lymphoblastic Leukemia

Background: Precursor B-Acute Lymphoblastic Leukemia (precursor B-ALL) oc-curs due to the uncontrolled proliferation of B-lymphoid precursors arrested at a par-ticular stage of B-cell development. Precursor-B-ALL is classified mainly into pro-B-ALL, common-ALL and pre-B-ALL. The Common Acute Lymphoblastic Antigen CD10 is the marker for common-ALL. Objective: This study was aimed to examine the ...

Characterization of Immunophenotypic Aberrancies in Adult and Childhood Acute Lymphoblastic Leukemia: Lessons from Regional Variation

Background & Objective: Although the antigen expression patterns of acute lymphoblastic leukemia (ALL) are well known, this study attempted to evaluate commonly used immune markers for immunophenotyping of acute leukemia to set the minimum of necessary diagnostic panels by flow cytometry. Methods: This study evaluated 89 patients referred from all over th...

Changes in Expression of miR-1297 and PTEN Tumor Suppressor Gene in T-cell Acute Lymphoblastic Leukemia

Background and purpose: T-cell acute lymphoblastic leukemia (T-ALL) is a type of blood malignancy caused by changes in the precursors of T lymphocyte cells. The PTEN gene is one of the most common tumor suppressor genes that mutates in most human cancers, including T-ALL. Therefore, it is important to identify miRNAs that target the PTEN gene in T-ALL. For this purpose, in the present study, mi...
