Biomarker Verification in Pediatric Chronic GvHD: ABLE 2.0 / PTCTC GVH 1901 Study
Chronic Graft-versus-Host-DiseaseLeukemia3 moreThis study will validate a previously developed pediatric prognostic biomarker algorithm aimed at improving prediction of risk for the later development of chronic graft-versus-host disease (cGvHD) in children and young adults undergoing allogeneic hematopoietic stem cell transplant. By developing an early risk stratification of patients into low-, intermediate-, and high-risk for future cGvHD development (based upon their biomarker profile, before the onset of cGvHD), pre-emptive therapies aimed at preventing the onset of cGvHD can be developed based upon an individual's biological risk profile. This study will also continue research into diagnostic biomarkers of cGvHD, and begin work into biomarker models that predict clinical response to cGvHD therapies.

Minitransplants With HLA-matched Donors : Comparison Between 2 GVHD Prophylaxis Regimens
Graft-Versus-Host DiseaseHematological MalignanciesThe present project is a multicenter phase II trail aiming at comparing which of the two postgrafting immunosuppressive regimens proposed in this study will be best suited to prevent graft-versus-host disease (GVDH). The immunosuppressive regimens will consist of: Tacrolimus plus Mycophenolate Mofetil or Tacrolimus plus Sirolimus. Before grafting patients will undergo a reduced-intensity conditioning with Fludarabine/total body irradiation (TBI) or Fludarabine/Busulfan/anti-thymoglobuline. Following the interim analysis of October 2014, the protocol has been amended to allow inclusion only after Flu-TBI conditioning. The hypothesis is that the Tacrolimus plus Sirolimus regimen will be associated with better progression-free survival due to a lower incidence of relapse/progression.
Low-Flow vs. High-Flow Nasal Cannula for Hypoxemic Immunocompromised Patients During Diagnostic...
ImmunocompromisedHematologic Malignancy3 morePneumonia is a lung infection. Fiberoptic bronchoscopy is a test to diagnose the type of lung infection. While this procedure is being performed, a small amount of oxygen is delivered into the nose (low flow nasal cannula). Occasionally during this procedure, the blood oxygen of the patient may drop and an intervention such as increasing the oxygen flow, or placing the patient on a breathing machine is required. An alternative device called 'Optiflow' can provide high flow oxygen through nasal cannula, and is comfortable for patients. If Optiflow is used during bronchoscopy, it may prevent the blood oxygen from dropping.

Social Relationships and Accelerated Aging in Hematopoietic Cell Transplant Survivors
Hematopoietic and Lymphoid Cell NeoplasmThis project aims to elucidate the important protective elements of social relationships and identify concrete, modifiable behavioral factors that contribute to biological and phenotypic aging in hematopoietic cell transplantation (HCT) survivors and can be used to develop biologically informed interventions to improve quality of life and prolong the healthspan of individuals with accelerated aging.

Covid-19 in Hematological Malignancies
COVID-19 Infection in Hematological Malignancies PatientsThe overall purpose of this project is to better understand the epidemiology of COVID-19 in patients with hematological malignancies (including hematopoietic stem cell transplant recipients) in the different European Countries. The results obtained will allow us to better know the prevalence of this complication in the different categories of patients with hematological malignancies (HMs). In order to attain the objectives previously described we will develop a multicentre, international, observational, retrospective and prospective study of consecutive cases of COVID-19 among HMs. There will be a clinical follow-up of the patients included in this study to observe the survival rate. Data collected form this study will be evaluated with a descriptive analysis.
Solving Riddles Through Sequencing
LeukemiaHematologic Malignancy4 moreDuring the last decades hematologists have excelled at improving and refining the classification, diagnosis, and thus ultimately the therapeutic decision-making process for their patients. This continuous evolution proceeded in parallel to seminal discoveries in basic science such as FISH, PCR and NGS. So far, the current WHO classification serves as reference to diagnostic decision making and is largely based on 5 diagnostic pillars: cytomorphology of peripheral blood and/or bone marrow smears, histology and immunohistochemistry of bone marrow trephine biopsies or lymph nodes, immunophenotyping, chromosome banding analysis supplemented by FISH analysis, molecular genetics including PCR and targeted panel sequencing via NGS. This leads to a swift diagnosis in 90 % of all cases. The leftover 10 % remain a challenge for hematopathologists and clinicians alike and are resolved through interdisciplinary teams in the context of specialized boards. With the advent of high throughput sequencing (mainly WGS and WTS) the possibility of a comprehensive and detailed portrait of the genetic alterations - specifically in challenging cases - has become a realistic alternative to classical methods. In SIRIUS the investigators will prospectively challenge this hypothesis to address the question of how often a better or final diagnosis can be delivered by WGS and/or WTS and if unclear cases can be efficiently resolved.
