Prognostic Impact of Copy Number Alterations' Profile and AID/RAG Signatures in Acute Lymphoblastic Leukemia (ALL) with BCR::ABL and without Recurrent Genetic Aberrations (NEG ALL) Treated with Intensive Chemotherapy.

Adult acute lymphoblastic leukemia (ALL) is associated with poor outcomes. ALL is initiated by primary aberrations, but secondary genetic lesions are necessary for overt ALL. In this study, we reassessed the value of primary and secondary aberrations in intensively treated ALL patients in relation to mutator enzyme expression.

IDH2 mutations in patients with normal karyotype AML predict favorable responses to daunorubicin, cytarabine and cladribine regimen.

Mutations in isocitrate dehydrogenase 1 and 2 (IDH1/2) genes occur in about 20% patients with acute myeloid leukemia (AML), leading to DNA hypermethylation and epigenetic deregulation. We assessed the prognostic significance of IDH1/2 mutations (IDH1/2) in 398 AML patients with normal karyotype (NK-AML), treated with daunorubicine + cytarabine (DA), DA + cladribine (DAC), or DA + fludarabine. IDH2 mutation was an independent favorable prognostic factor for 4-year overall survival (OS) in total NK-AML population (p = 0.

Successful Use of Nilotinib in the Therapy of a Patient with a Chemoresistant Relapse of BCR-ABL1-Like Phenotype Acute Lymphoblastic Leukemia.

Introduction: Relapse of acute lymphoblastic leukemia (ALL) after allogeneic hematopoietic cell transplantation (HCT) is a therapeutic challenge. We present the case of a 20-year-old patient with a relapse of Philadelphia chromosome-negative ALL B-common over 2 years after HCT with no response to salvage chemotherapy or blinatumomab, who finally responded to a molecularly tailored therapy adjusted to the BCR-ABL1-like phenotype.

Methods: The BCR-ABL1-like phenotype was diagnosed on the basis of an increased expression of ABL1 and CRLF2 genes.

CEBPA copy number variations in normal karyotype acute myeloid leukemia: Possible role of breakpoint-associated microhomology and chromatin status in CEBPA mutagenesis.

Copy number variations (CNV) in CEBPA locus represent heterogeneous group of mutations accompanying acute myeloid leukemia (AML). The aim of this study was to characterize different CEBPA mutation categories in regard to biological data like age, cytology, CD7, and molecular markers, and identify possible factors affecting their etiology. We report here the incidence of 12.

[Development of a novel real-time PCR method for detection of HSV types 1 and 2 DNA using HybProbe chemistry].

Herpes simplex viruses types 1 and 2 are members of the Alphaherpesviridae subfamily, as they can infect both skin and nerves and develop latent infection within the dorsal root and trigeminal ganglia. Infections with these viruses are common worldwide and cause wide range of clinical syndromes. Although HSV-1/2 infect healthy children and adults, disease is more severe and extensive in the immunocompromised individuals and/or during neuroinfections.

Herpes simplex virus type 1 is a member of the Alphaherpesviridae subfamily, as it can infect both skin and nerves and develop latent infection within the dorsal root and trigeminal ganglia. Infection with this virus is common and causes a wide range of clinical syndromes. Although HSV-1 infect healthy children and adults, disease is more severe and extensive in the immunocompromised individuals.
