Validation of the revised international prognostic scoring system (IPSS-R) in patients with myelodysplastic syndrome: a multicenter study.

2013

The revised IPSS (IPSS-R) was developed aiming at a better prognostication, taking into account patients treated with best supportive care. We herein validated this model on the basis of data from 1314 patients who received BSC only as well as patients who underwent induction chemotherapy (n=214) or allogeneic transplantation (n=167). We could demonstrate a clear distinction of the IPSS-R risk categories with regard to survival and risk of AML evolution in all patient cohorts. When comparing IPSS-R, IPSS, WHO prognostic scoring system (WPSS) and Duesseldorf score, the best results regarding the ability to predict survival were obtained by the IPSS-R.

Whole-brain radiotherapy or autologous stem-cell transplantation as consolidation strategies after high-dose methotrexate-based chemoimmunotherapy in…

2017

Background The International Extranodal Lymphoma Study Group-32 (IELSG32) trial is an international randomised phase 2 study that addresses two key clinical questions in the treatment of patients with newly diagnosed primary CNS lymphoma. Results of the first randomisation have demonstrated that methotrexate, cytarabine, thiotepa, and rituximab (called the MATRix regimen) is the induction combination associated with significantly better outcome compared with the other induction combinations tested. Here, we report the results of the second randomisation that addresses the efficacy of myeloablative chemotherapy supported by autologous stem-cell transplantation (ASCT), as an alternative to wh…

Treatment of embryonal tumors with multilayered rosettes with carboplatin/etoposide induction and high-dose chemotherapy within the prospective P-HIT…

2021

Abstract Background Embryonal tumors with multilayered rosettes (ETMR) are highly aggressive tumors occurring in early childhood. Published clinical data refer to retrospective, heterogeneously treated cohorts. Here, we describe the outcome of patients treated according to the prospective P-HIT trial and subsequent HIT2000-interim-registry. Patients and methods Age-stratified treatment included carboplatin/etoposide induction, tandem high-dose chemotherapy (“CARBO/ETO + HDCT”), and response-stratified radiotherapy. Patients with centrally reviewed neuropathological and molecularly confirmed diagnosis of ETMR recruited within the P-HIT trial (2001-2011; n = 19), the HIT2000-interim-registry …

PKP-003 Influence of cytarabine metabolic pathway polymorphisms in effectiveness of acute myeloid leukaemia induction treatment

2017

Background Cytarabine is considered the most effective chemotherapeutic agent in the treatment of acute myeloid leukaemia (AML). Purpose Several studies suggest that single nucleotide polymorphisms (SNPs) in genes involving the metabolic pathway of cytarabine could influence treatment outcomes, although their clinical relevance remains undetermined. Material and methods The SNPs of cytarabine pathway (DCK:rs2306744, rs11544786, rs4694362; CDA:rs2072671, rs3215400, rs532545, rs602950; NT5C2:rs11598702; RRM1:rs9937; NME1:rs2302254) were evaluated in 225 adult patients at initial diagnosis of AML using a mass spectrometry based multiplex genotyping assay (Sequenom). All patients received induc…

First-Line XELOX plus bevacizumab followed by XELOX plus bevacizumab or single-agent bevacizumab as maintenance therapy in patients with metastatic c…

2012

Abstract Purpose. The aim of this phase III trial was to compare the efficacy and safety of bevacizumab alone with those of bevacizumab and capecitabine plus oxaliplatin (XELOX) as maintenance treatment following induction chemotherapy with XELOX plus bevacizumab in the first-line treatment of patients with metastatic colorectal cancer (mCRC). Patients and Methods. Patients were randomly assigned to receive six cycles of bevacizumab, capecitabine, and oxaliplatin every 3 weeks followed by XELOX plus bevacizumab or bevacizumab alone until progression. The primary endpoint was the progression-free survival (PFS) interval; secondary endpoints were the overall survival (OS) time, objective resp…

Phase III Trial of Avelumab Maintenance After First-Line Induction Chemotherapy Versus Continuation of Chemotherapy in Patients With Gastric Cancers:…

2021

PURPOSE The role of maintenance therapy for gastric (GC) or gastroesophageal junction cancer (GEJC) is unclear. We investigated avelumab (anti–programmed death ligand-1 [PD-L1]) maintenance after first-line induction chemotherapy for GC/GEJC. PATIENTS AND METHODS JAVELIN Gastric 100 was a global, open-label, phase III trial. Eligible patients had untreated, unresectable, human epidermal growth factor receptor 2–negative, locally advanced or metastatic GC or GEJC. Patients without progressive disease after 12 weeks of first-line chemotherapy with oxaliplatin plus a fluoropyrimidine were randomly assigned 1:1 to avelumab 10 mg/kg every 2 weeks or continued chemotherapy, stratified by region (…

Compassionate Use of Sorafenib in Relapsed and Refractory Flt3-ITD Positive Acute Myeloid Leukemia.

2009

Abstract Abstract 2060 Poster Board II-37 Introduction: The Flt3-internal tandem duplication can be found in up to 30% of all acute myeloid leukemia (AML) patients and confers a poor risk status characterized by an increased relapse rate and poor overall survival. Moreover, Flt3-ITD-positive AML patients relapsing after allogenic stem cell transplantation (SCT) have very limited therapeutic options. Sorafenib is a multikinase inhibitor that is approved for the treatment of metastatic renal cell and hepatocellular carcinoma. Besides targeting Raf, the platelet derived growth factor receptor (PDGFR) and the vascular endothelial growth factor receptor (VEGFR) it has also significant inhibitory…

PKP-020 Impact of nadph oxidase functional polymorphisms in acute myeloid leukaemia induction chemotherapy

2016

Background NADPH oxidase, a key mediator of oxidative cardiac damage and remodelling, modulates anthracycline clinical cardiotoxicity. Purpose Single nucleotide polymorphisms (SNPs) of NADPH oxidase genes could lead to interindividual differences in treatment outcome in acute myeloid leukaemia (AML) patients. Material and methods The main three NADPH oxidase polymorphisms (CYBA:rs4673, NCF4:rs1883112 and RAC2:rs13058338) were evaluated in 225 adult patients at the initial diagnosis of AML using a mass spectrometry based multiplex genotyping assay (Sequenom). All patients received induction chemotherapy consisting of idarubicin plus cytarabine (PETHEMA 99, 2007 and 2010 trials). The efficacy…

2015

Background Single nucleotide polymorphisms (SNPs) could lead to inter-individual differences in treatment outcomes. Purpose A recent study 1 reported several novel SNPs involved in cytarabine cytotoxicity using a whole-genome approach, which were associated with clinical outcomes in a paediatric AML population. However their association with effectiveness and toxicity remain undetermined in adults. Material and methods The six SNPs with clinical significance in the Gamazon study 1 (Table 1) were evaluated in 109 adult patients at initial diagnosis with AML using a mass spectrometry–based multiplex genotyping assay (Sequenom). All patients were treated with idarubicin plus cytarabine. Genoty…
