GM-CSF in a Double-Blind Randomized Placebo-Controlled Trial in Therapy of Adult Patients with De Novo Acute Myeloid Leukemia
1994
Despite the fact that 60%–70% of patients with de novo acute myeloblastic leukemia (AML) achieve a complete remission (CR) of the disease only about 20%–30% of the patients remain in long term remission and are probably cured [1,2]. These rather disappointing long-term results argue in favor of an even more intensive induction and post-remission therapy. This intention is, however, at time limited by therapy associated toxicity. Especially haematotoxicity seems to be the limiting factor in that patients with profound neutropenia are at high risk of developing fatal infectious complications [3]. In this context haematopoietic growth factors, such as granulocyte-macrophage colony-stimulating …
Favorable Outcome in Patients with Acute Myeloblastic Leukemia (AML) with NPM1 Mutation Who Present an Inadequate Clearance or Relapse of Minimal/Mea…
2018
Abstract Introduction Patients diagnosed with AML with NPM1mutation (NPM1mut AML) included in the European LeukemiaNet favorable genetic risk category (ELNfav, i.e., without FLT3-ITD or with a low allelic burden FLT3-ITD comutation [FLT3-ITD/FLT3wt <0.5; FLT3-ITDLOW]) do not benefit from an allogeneic stem cell transplantation (alloSCT) in first complete remission (CR1). However, a significant proportion of these patients fail to frontline chemotherapy and require salvage therapy. Persistence or detection of MRD after post-CR treatment is associated with a high relapse risk and worse prognosis. With this background, the cooperative group CETLAM proposed an early therapeutic intervention …

Two independent epigenetic biomarkers predict survival in neuroblastoma.
2015
Background Neuroblastoma (NB) is the most common extracranial pediatric solid tumor with a highly variable clinical course, ranging from spontaneous regression to life-threatening disease. Survival rates for high-risk NB patients remain disappointingly low despite multimodal treatment. Thus, there is an urgent clinical need for additional biomarkers to improve risk stratification, treatment management, and survival rates in children with aggressive NB. Results Using gene promoter methylation analysis in 48 neuroblastoma tumors with microarray technology, we found a strong association between survival and gene promoter hypermethylation (P = 0.036). Hypermethylation of 70 genes significantly …
Outcomes in 370 patients with mantle cell lymphoma treated with ibrutinib: a pooled analysis from three open-label studies
2017
Ibrutinib is highly active in treating mantle cell lymphoma (MCL), an aggressive B-cell lymphoma. We pooled data from three ibrutinib studies to explore the impact of baseline patient characteristics on treatment response. Patients with relapsed/refractory MCL (n = 370) treated with ibrutinib had an objective response rate (ORR) of 66% (20% complete response; 46% partial response); median duration of response (DOR), progression-free survival (PFS) and overall survival (OS) were 18.6, 12.8 and 25.0 months, respectively. Univariate analyses showed patients with one versus >one prior line of therapy had longer OS. Multivariate analyses identified that one prior line of therapy affected PFS; Ea…
Evaluation of Prognostic Factors and Role of Participation in a Randomized Trial or a Prospective Registry in Pediatric and Adolescent Nonmetastatic …
2020
Purpose: We aimed to compare treatment results in and outside of a randomized trial and to confirm factors influencing outcome in a large retrospective cohort of nonmetastatic medulloblastoma treated in Austria, Switzerland and Germany. Methods and Materials: Patients with nonmetastatic medulloblastoma (n = 382) aged 4 to 21 years and primary neurosurgical resection between 2001 and 2011 were assessed. Between 2001 and 2006, 176 of these patients (46.1%) were included in the randomized HIT SIOP PNET 4 trial. From 2001 to 2011 an additional 206 patients were registered to the HIT 2000 study center and underwent the identical central review program. Three different radiation therapy protocols…
With a Little Help from My Friends: The Role of Intraoperative Fluorescent Dyes in the Surgical Management of High-Grade Gliomas
2018
High-grade gliomas (HGGs) are the most frequent primary malignant brain tumors in adults, which lead to death within two years of diagnosis. Maximal safe resection of malignant gliomas as the first step of multimodal therapy is an accepted goal in malignant glioma surgery. Gross total resection has an important role in improving overall survival (OS) and progression-free survival (PFS), but identification of tumor borders is particularly difficult in HGGS. For this reason, imaging adjuncts, such as 5-aminolevulinic acid (5-ALA) or fluorescein sodium (FS) have been proposed as superior strategies for better defining the limits of surgical resection for HGG. 5-aminolevulinic acid (5-ALA) is i…
MTHFR and VDR Polymorphisms Improve the Prognostic Value of MYCN Status on Overall Survival in Neuroblastoma Patients
2020
Single nucleotide polymorphisms (SNPs) in Pharmacogenetics can play an important role in the outcomes of the chemotherapy treatment in Neuroblastoma, helping doctors maximize efficacy and minimize toxicity. Employing AgenaBioscience MassArray, 96 SNPs were genotyped in 95 patients looking for associations of SNP with response to induction therapy (RIT) and grade 3&ndash
Robust association between vascular habitats and patient prognosis in glioblastoma: An international multicenter study
2019
Background Glioblastoma (GBM) is the most aggressive primary brain tumor, characterized by a heterogeneous and abnormal vascularity. Subtypes of vascular habitats within the tumor and edema can be distinguished: high angiogenic tumor (HAT), low angiogenic tumor (LAT), infiltrated peripheral edema (IPE), and vasogenic peripheral edema (VPE). Purpose To validate the association between hemodynamic markers from vascular habitats and overall survival (OS) in glioblastoma patients, considering the intercenter variability of acquisition protocols. Study Type Multicenter retrospective study. Population In all, 184 glioblastoma patients from seven European centers participating in the NCT03439332 c…
