The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 2.4 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 2.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.5 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00049 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.59 SJR: 0.429 SNIP: 0.507 CiteScore™:: 3.9 H-Index: 49

ABSTRACT

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. Among the study group analyzed, a significantly higher frequency of BCR/ABL1 gene rearrangements that is consistent with der(9) deletion were observed in the blast crisis (BC) phase at 41.67%, followed by the accelerated phase (AP) at 36.84%, the imatinib mesylate (IM)-resistant chronic phase (CP) at 23.08%, and the lowest incidence was found in de novo CP at 16.61%. 1R1G1F (1 red, 1 green, 1 fusion) with concurrent loss of ABL1-BCR fusion gene on der(9) chromosome was the major signal pattern identified in each group. The results from the current study show that this unusual BCR/ABL1 gene rearrangement is one of the steering forces toward disease progression in CML. Patients in AP/BC of CML with der(9) deletion showed poor response to IM therapy; however, patients with der(9) deletion in the early phases of CML responded well to IM treatment. Therefore, the establishment of an atypical FISH signal pattern in CML is of paramount important because it is associated with adverse clinical prognostic implications in advanced stages of the disease.
