High-dose methotrexate (Hd-MTX) therapy has recently been applied to the treatment of adult acute lymphoblastic leukemia (ALL) based on pediatric protocols; however, its effectiveness for adult ALL has not yet been confirmed in a rigorous manner. We herein conducted a randomized phase III trial comparing Hd-MTX therapy with intermediate-dose (Id)-MTX therapy. This study was registered at UMIN-CTR (ID: C000000063). Philadelphia chromosome (Ph)-negative ALL patients aged between 25 and 64 years of age were enrolled...

Despite advances in treatment, children with acute lymphoblastic leukemia (ALL) still experience drug resistance and relapse. Several gene mutations are involved in the onset of this disease and resistance to therapy. The present study examines the incidence of IKZF1, CDKN2A/B, PAX5, EBF1, ETV6, BTG1, RB1, JAK2, and Xp22.33 gene deletions/duplications associated with pediatric ALL in Iran and investigates the possible effect of these mutations on drug resistance. Three-year disease-free survival (3DFS) was evaluated for children diagnosed with Philadelphia negative precursor-B-cell ALL hospitalized at Sayed-al-Shohada Hospital, Isfahan-Iran, from January 2009 until December 2012...

BACKGROUND: As one of the major treatment obstacles in Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph(+)ALL), relapse of Ph(+)ALL may result from the persistence of leukemia-propagating cells (LPCs). Research using a xenograft mouse assay recently determined that LPCs were enriched in the CD34(+)CD38(-)CD58(-) fraction in human Ph(+)ALL. Additionally, a cohort study demonstrated that Ph(+)ALL patients with a LPCs phenotype at diagnosis exhibited a significantly higher cumulative incidence of relapse than those with the other cell phenotypes even with uniform front-line imatinib-based therapy pre- and post-allotransplant, thus highlighting the need for novel LPCs-based therapeutic strategies...

Philadelphia chromosome-like acute lymphoblastic leukemia (Ph-like ALL) is a recently described B-cell precursor ALL with a gene expression profile and a high frequency of IKZF1 gene alteration similar to that of Ph-positive ALL. Its prevalence is approximately 12% in children, 21% in adolescents (16-20 years of age), and 20% to 24% in adults older than 40 years, with a peak (27%) in young adults 21 to 39 years old. It occurs more often in male individuals and patients with Down syndrome. Ph-like ALL is overrepresented in those with Hispanic ethnicity and is associated with inherited genetic variants in GATA3 (rs3824662)...

AIMS: Acute lymphoblastic leukemia (ALL) is an aggressive form of leukemia with a poor prognosis in adult patients. The addition of the monoclonal antibody rituximab to standard chemotherapy has been shown to improve survival in adults with ALL. However, it is unknown whether the addition of rituximab is cost-effective. Our objective was to determine the economic impact of rituximab in addition to standard of care (SOC) chemotherapy vs. SOC alone in newly diagnosed Philadelphia chromosome-negative, CD20-positive, B-cell precursor ALL...

Clonal chromosomal abnormalities in Philadelphia chromosome-negative metaphases (CCA/Ph-) emerge as patients with chronic phase chronic myeloid leukemia (CP-CML) are treated with tyrosine kinase inhibitors (TKI). We assessed the characteristics and prognostic impact of 598 patients with CP-CML treated on clinical trials with various TKIs. CCA/Ph- occurred in 58 patients (10%) and the most common were - Y in 25 (43%) and trisomy 8 in 7 patients (12%). Response to TKI therapy was similar for patients with CCA/Ph- and those without additional chromosomal abnormalities (ACAs)...

CML originates due to reciprocal translocation in Philadelphia chromosome leading to formation of fusion product BCR-ABL which constitutively activates tyrosine kinase signaling pathways eventually abnormal proliferation of granulocytic cells. As a therapeutic strategy, BCR-ABL inhibitors have been clinically approved which terminates its phosphorylation activity and retards cancer progression. However,number of patients develops resistance to inhibitors which demand for discovery of new inhibitors. Given the drawbacks of present inhibitors, by high throughput virtual screening approaches, present study pursues to identify high affinity compounds targeting BCR-ABL1 anticipated to have safer pharmacological profiles...

BACKGROUND: Calls for public reporting of outcomes in congenital heart surgery have led to several different reporting schemes, including a star rating system and benchmark procedure-specific mortality data tables. Important unanswered questions remain about the optimal format and content of public reporting of congenital heart surgery outcomes. METHODS: In conjunction with three parent advocacy groups, we developed a questionnaire to gauge parents' attitudes regarding the format and content of an "optimal" public reporting scheme...

Intravenous inotuzumab ozogamicin (Besponsa(®); Pfizer) is an anti-CD22 monoclonal antibody-calicheamicin conjugate that binds to CD22-expressing tumour cells. Upon binding, the complex is internalised and the cytotoxic calicheamicin derivative is released inside the cell, inducing double-strand DNA breakage and subsequent cell death. In June 2017, the EMA granted inotuzumab ozogamicin approval as monotherapy for the treatment of adults with relapsed or refractory CD22-positive B-cell precursor acute lymphoblastic leukaemia (ALL)...

BCR-ABL1-targeting tyrosine kinase inhibitors (TKIs) have revolutionized treatment of Philadelphia chromosome-positive (Ph(+)) hematologic neoplasms. Nevertheless, acquired TKI resistance remains a major problem in chronic myeloid leukemia (CML), and TKIs are less effective against Ph(+) B-cell acute lymphoblastic leukemia (B-ALL). GAB2, a scaffolding adaptor that binds and activates SHP2, is essential for leukemogenesis by BCR-ABL1, and a GAB2 mutant lacking SHP2 binding cannot mediate leukemogenesis. Using a genetic loss-of-function approach and bone marrow transplantation models for CML and BCR-ABL1(+) B-ALL, we show that SHP2 is required for BCR-ABL1-evoked myeloid and lymphoid neoplasia...

OBJECTIVE: The ability to use electronic medical records (EMR) is an essential skill for surgical residents. However, frustration and anxiety surrounding EMR tasks may detract from clinical performance. We created a series of brief, 1-3 minutes "how to" videos demonstrating 7 key perioperative EMR tasks: booking OR cases, placing preprocedure orders, ordering negative-pressure wound dressing supplies, updating day-of-surgery history and physical notes, writing brief operative notes, discharging patients from the postanesthesia care unit, and checking vital signs...

BACKGROUND: Medical schools have a major impact on future doctors' ethics and their attitudes towards cooperation with the pharmaceutical industry. From childhood, medical students who are related to a physician are exposed to the characteristics of a medical career and learn its professional ethics not only in school but also in the family setting. The present paper sought to answer the research question: 'How does growing up with a physician influence medical students' perceptions of conflicts of interest in their relationships with industry?' METHODS: An anonymous questionnaire was completed by 451 medical students from four Philadelphia medical schools and 554 medical students from Warsaw Medical University during 2013...

Multiple cytogenetic subgroups have been described in adult Philadelphia chromosome (Ph)-negative B-cell precursor (BCP) acute lymphoblastic leukemia (ALL), often comprising small numbers of patients. In this study, we aimed to reassess the prognostic value of cytogenetic abnormalities in a large series of 617 adult patients with Ph-negative BCP-ALL (median age, 38 years), treated in the intensified GRAALL-2003/2005 trials. Combined data from karyotype, DNA index, FISH and/or PCR screening for relevant abnormalities were centrally reviewed and were informative in 542 cases (88%), allowing classification in ten exclusive primary cytogenetic subgroups and in secondary subgroups including complex and monosomal karyotypes...
