From Six Gene Polymorphisms of the Antioxidant System, Only GPX Pro198Leu and GSTP1 Ile105Val Modulate the Risk of Acute Myeloid Leukemia.

Oxidative stress might contribute to the occurrence of cancers, including the hematological ones. Various genetic polymorphisms were shown to increase the quantity of reactive oxygen species, a phenomenon that is able to induce mutations and thus promote cancers. The purpose of the study was to evaluate the association between CAT C262T, GPX1 Pro198Leu, MnSOD Ala16Val, GSTM1, GSTT1, and GSTP1 Ile105Val gene polymorphisms and acute myeloid leukemia risk, in a case-control study comprising 102 patients and 303 controls.

Real-time quantitative PCR detection of WT1 and M-BCR-ABL expressions in chronic myeloid leukemia.

Unlabelled: The Philadelphia chromosome and the resulting BCR-ABL fusion gene represent the hallmark event in chronic myeloid leukemia (CML) and their discoveries radically changed the management of these patients. Currently Wilms tumor 1 gene (WT1) is intensively investigated as high WT1 expression levels have been demonstrated in case of multiple solid tumors and malignant hematological syndromes (acute myeloid and lymphoid leukemia, myelodysplastic syndromes and chronic myeloid leukemia). The aim of our study was to investigate the WT1 expression in CML patients and its possible contribution to disease evolution.

Histopathological, immunophenotypic and clinical particularities and evolution of a case of hepatosplenic T-cell lymphoma in transformation to leukemia.

We present the possibilities of diagnosis correlating the pathological, immunophenotyping and clinical aspects of a rare case of T-cell lymphoma in a 23-year-old patient with leukemic transformation. In our consideration, it is very important to describe this case because in the literature there are very few cases presented and the treatment of this type of lymphoma does not present optimal results, the evolution of the patients being from three months to two years. The treatment modality that gives the possibility to prolong survival and cure is hematopoietic stem cell transplantation.

Monitoring M-BCR-ABL expression level in CML patients by RQ-PCR: experience of a single Center.

Unlabelled: Chronic myelogenous leukemia (CML) is characterized by the Philadelphia chromosome and the BCR-ABL fusion gene that encodes an abnormal tyrosine kinase. Development of specific tyrosine kinase inhibitors completely changed the management of these patients.

Materials And Methods: Between April 2008 and July 2012, at the Molecular Biology Laboratory, University of Medicine and Pharmacy of Targu Mures, Romania, we monitored the M-BCR-ABL transcript level by real time quantitative PCR in case of 15 CML patients diagnosed at the Hematology and Transplant Center of Targu Mures.
