Towards More Specificity and Effectivity in the Antileukemia Immune Response

2014

Experimental and clinical studies have shown that alloreactive T-cell responses derived from donor lymphocytes can effectively eliminate leukemia cells after allogeneic hematopoietic stem cell transplantation. However, there are still too many patients in whom this graft-versus-leukemia reactivity is insufficient to prevent leukemia relapse or who suffer from severe alloreactivity to nonmalignant host tissues also mediated by donor-derived T cells. Therefore, various conceptually different approaches have been developed at the level of donor T cells in order to improve the efficacy of leukemia-directed immunity while reducing the incidence of unwanted graft-versus-host disease. As outlined …

Arsenic Trioxide Abrogate MN1 Mediated RA-Resistance in Acute Promyelocytic Leukemia

2019

Introduction: Described as a well know marker of worse prognosis in acute myeloid leukemia (AML), MN1 overexpression has been associated with inv(16) or EVI1 overexpression (Heuser et al., Blood 2007). The promoter region of the MN1 gene has Retinoic Acid Response Elements (RAREs), and higher levels of MN1 expression have been associated with decreased response to retinoic acid (RA) in vitro. Nevertheless, in the context of acute promyelocytic leukemia, little is known about MN1 gene expression and functionality in vivo. Aims: Here, we investigated the effects of in vitro treatment with RA plus arsenic trioxide (ATO) in APL cell lines and primary blasts overexpressing MN1. Additionally, we …

Treatment Results In Acute Myeloid Leukemia Over a Time Period Of 20 Years: Analysis Of The German-Austrian Acute Myeloid Leukemia Study Group (AMLSG)

2013

Abstract Background Overall survival (OS) in acute myeloid leukemia (AML) treated with intensive chemotherapy has improved over the last 20 year especially in younger adults (18-60 years) but still remains poor in older patients (>60 years) (Döhner et al. Blood 2010). The German-Austrian AMLSG performed controlled prospective treatment trials since 1993 starting with a risk-adapted approach (phase I, 1993-1997), followed by randomized and risk-adapted treatment strategies based on cytogenetic risk groups (phase II, 1997-2002); since 2003 addition of differentiating agents and HiDAC inhibitors to intensive induction therapy was evaluated (phase III, 2003-2007). Of note, until 2007 younger…

Management of acute promyelocytic leukemia: updated recommendations from an expert panel of the European LeukemiaNet

2019

Abstract Since the comprehensive recommendations for the management of acute promyelocytic leukemia (APL) reported in 2009, several studies have provided important insights, particularly regarding the role of arsenic trioxide (ATO) in frontline therapy. Ten years later, a European LeukemiaNet expert panel has reviewed the recent advances in the management of APL in both frontline and relapse settings in order to develop updated evidence- and expert opinion–based recommendations on the management of this disease. Together with providing current indications on genetic diagnosis, modern risk-adapted frontline therapy, and salvage treatment, the review contains specific recommendations for the …

Insufficienza renale acuta in paziente con carcinoma epatocellulare sottoposto a chemioembolizzazione transarteriosa

2007

Transarterial chemoembolization (TACE) is included among the wide therapeutic tools for the treatment of hepatocellular carcinoma (HCC), tumour with high frequency and malignancy. The approach is invasive and, beyond the discomfort for the patient, it is charged by a number of side effects and complications. In this study we report the case of renal acute failure of hypovolemic origin, as a consequence of a TACE in a patient suffering from HCC, occurred after one week of intervention. The different possible mechanisms involved in the pathogenesis of this complication are discussed.

Worldwide trends in population-based survival for children, adolescents, and young adults diagnosed with leukaemia, by subtype, during 2000–14 (CONCO…

2022

BACKGROUND Leukaemias comprise a heterogenous group of haematological malignancies. In CONCORD-3, we analysed data for children (aged 0-14 years) and adults (aged 15-99 years) diagnosed with a haematological malignancy during 2000-14 in 61 countries. Here, we aimed to examine worldwide trends in survival from leukaemia, by age and morphology, in young patients (aged 0-24 years). METHODS We analysed data from 258 population-based cancer registries in 61 countries participating in CONCORD-3 that submitted data on patients diagnosed with leukaemia. We grouped patients by age as children (0-14 years), adolescents (15-19 years), and young adults (20-24 years). We categorised leukaemia subtypes a…

Influence of polymorphisms in anthracyclines metabolism genes in the standard induction chemotherapy of acute myeloid leukemia

2021

Objectives Genetic variability in anthracycline metabolism could modify the response and safety of acute myeloid leukemia (AML) induction. Methods Polymorphisms in genes that encodes enzymes of anthracyclines metabolic pathway (CBR3: rs1056892, rs8133052, NQO1: rs1800566, NQO2: rs1143684, NOS3: rs1799983, rs2070744) were evaluated in 225 adult de novo AML patients. Results The variant CBR3 rs8133052 was associated with lower hepatotoxicity (P = 0.028). Wild-type genotype of NQO2 rs1143684 was related to higher complete remission (P = 0.014), and the variant allele with greater gastrointestinal toxicity (P = 0.024). However, the variant genotype of NQO1 rs1800566 was associated with mucositi…

Impact of coronavirus disease 2019 (COVID-19) outbreak on radiology research: An Italian survey

2021

Abstract Purpose To understand how COVID-19 pandemic has changed radiology research in Italy. Methods A questionnaire (n = 19 questions) was sent to all members of the Italian Society of Radiology two months after the first Italian national lockdown was lifted. Results A total of 327 Italian radiologists took part in the survey (mean age: 49 ± 12 years). After national lockdown, the working-flow came back to normal in the vast majority of cases (285/327, 87.2%). Participants reported that a total of 462 radiological trials were recruiting patients at their institutions prior to COVID-19 outbreak, of which 332 (71.9%) were stopped during the emergency. On the other hand, 252 radiological tri…
