Aim: This study explores the prognostic impact of FLT3-ITD, NPM1, and WT1 mutations both independently and in combination in Cytogenetically Normal Acute Myeloid Leukemia (CN-AML) patients as they exhibit varying clinical outcomes.

Methods: 150 CN-AML patients were selected to assess the prevalence and prognostic significance of WT1 mutations in combination with FLT3-ITD and NPM1 status using polymerase chain reaction (PCR) followed by Sanger sequencing.

Results: WT1 exon 7 mutations were present in 12.

Comprehensive theory explaining the relationship between estrogen (E2) and ezrin in metastasis of thyroid cancer remains non-elicited. In vitro results revealed that E2 could stimulate the expression and phosphorylation of ezrin in a time and dose dependent manner. Our data clearly showed that E2 enhanced the migration and invasion of cells, which was reversed by the transfection of cells with ezrin specific siRNA.

The emergence of additional chromosomal abnormalities (ACAs) in Philadelphia chromosome/ positive chronic myeloid leukemia (CML), is considered to be a feature of disease evolution. However, their frequency of incidence, impact on prognosis and treatment response effect in CML is not conclusive. In the present study, we performed a chromosome analysis of 489 patients in different clinical stages of CML, using conventional GTG-banding, Fluorescent Hybridization and Spectral Karyotyping.

Identification of BCR-ABL1 fusion gene amplification status is critically important in the effective management of chronic myelogenous leukemia (CML) patients. Earlier reports suggested that overexpression of BCR-ABL1 either through amplification of BCR-ABL1 fusion gene or by the up regulation of BCR-ABL1 transcript level might be an early phenomenon in the establishment of IM resistance and disease evolution in CML. In the current study, we performed dual color dual fusion locus specific BCR/ABL1 FISH analysis along with karyotype analysis using GTG banding (G-banding using trypsin and Giemsa) technique in 489 patients with different clinical stages of CML at diagnosis or during the course of the disease to unravel the spectrum of BCR-ABL1 fusion gene amplification status.

Elucidation of cryptic BCR/ABL1 gene rearrangement is exceptionally important in the clinical diagnosis and prognosis of chronic myelogenous leukemia (CML). Previous reports indicated an adverse prognostic effect of atypical BCR/ABL1 gene rearrangements with submicroscopic ABL1-BCR deletions on derivative chromosome 9 [der(9)] in CML patients. Dual color dual fusion locus-specific BCR/ABL1 fluorescent in situ hybridization (FISH) analysis together with G-banding using trypsin and Giemsa (GTG banding) was performed in 489 patients at different stages of CML to investigate the spectrum of BCR/ABL1 gene rearrangements.
