Active clinical trials for "Precursor Cell Lymphoblastic Leukemia-Lymphoma"

Although COVID-19 infects gastrointestinal tissues, little is known about the roles of gut commensal microbes in susceptibility to and severity of infection. The investigators will analyze the alterations in fecal microbiomes of patients with COVID-19 infection during hospitalization.

Retrospective observational study with systematic collection of data on filiation (age at diagnosis and sex), clinical data (IPI, ECOG, early response to chemotherapy, overall response to chemotherapy), biological (strain B or T, infiltration of the nervous system central [CNS], bone marrow [MO], lactate dehydrogenase (LDH) level at the time of diagnosis, as well as genetic patients included in the study, as well as the PETHEMA protocol used in the treatment of same patients The study will review the PETHEMA protocols from 2003 to the present

AlloHeme is a chimerism test service that utilizes NGS technology to analyze SNP loci to quantify donor and recipient cells by measuring genomic DNA. Before transplant, patient and donor peripheral blood sample will be collected to identify informative marker for routine chimerism testing and baseline establishment for AlloHeme. Post-transplant blood or bone marrow samples are obtained and compared to the baseline sample profiles to calculate % chimerism of recipient cells in the blood and/or bone marrow samples. Cell selection from blood and bone marrow samples is applied to evaluate chimerism in specific cell subtypes that are relevant to AML and MDS diseases (CD3+ T lymphocytes, CD33+ Myeloid cells and CD15+ Granulocyte cell subtypes from blood and CD34+ hematopoietic stem cells from bone marrow).

In acute lymphoblastic leukemia (ALL), the occult central nervous system (CNS) involvement appears to be associated with poor prognosis. Flow cytometry (FCM) allows detection of occult CNS localization. The current international guidelines do not recommend the use of FCM in the assessment of CNS at onset in adult ALL patients. Large-scale prospective studies will help to clarify whether or not patients with occult CNS localization should undergo CNS-directed therapy. Understanding this seems particularly important nowadays considering that with the introduction of new drugs (monoclonal antibodies, next-generation tyrosine kinase inhibitors, CAR-T) the therapeutic approach of patients with ALS is increasingly "chemo-free"

The LALGFA2019 Recommendations redefine the standard risk criteria and propose to introduce anthracycline induction in so-called high-risk forms (LAL line T and LAL line B with leukocytosis greater than or equal to 50 G/L or in children less than 1 year of age or more than 10 years of age) as well as Endoxan and Methotrexate in high dose consolidation.

The purpose of this study is to prospectively validate the new risk model, based on minimal residual disease (MRD) response level and oncogenetic status by comparing historical results of GRAALL-2005 with those of GRAALL-2014 in an identical population of patients (Philadelphia chromosome negative, B lineage ALL, aged 18 to 59 years old).

Replacement of intrathecal Triple (methotrexate, cytarabine, prednisolone) with intrathecal liposomal cytarabine and prednisolone during maintenance therapy will decrease the CNS relapse rate in high-risk ALL patients. Both acute and long-term toxicity are equal in both treatment arms.

A comprehensive mechanistic and epidemiological study to obtain banked cord blood samples from consecutive childhood leukemia patients enrolled in the COG Project:EveryChild (APEC14B1) study. Will attempt to backtrack the initiating genomic alteration identified in the matched diagnostic leukemia sample and molecularly characterize pre-leukemic cells. The ultimate goal of this research is to pinpoint the cell of origin of leukemogenic alterations formed in utero, elucidating the etiology of these initiating mutations (as opposed to frank leukemia), and devising a test for circulating pre-leukemia that can be applied on a population-wide basis.

The overall goals of this study are to measure parents' financial distress (worry or anxiety about money) during their child's/adolescent's treatment for acute lymphoblastic leukemia and whether it changes over time, and to learn what factors are associated with changes in financial distress. Information gathered from this study will inform future intervention studies that may mitigate financial distress for parents of children/adolescents being treated for acute lymphoblastic leukemia.

Acute lymphoblastic leukemia (ALL) is the most common cancer of childhood and long-term survival has risen to above 90%, but 1-4% of treated patients die from infections. Early detection and treatment of infection can improve these outcomes by preventing increased severity and death. This study aims to determine whether continuous analysis of information from wearable devices (Like a watch and sticky patch) that measure temperature, pulse rate, oxygen level, and other similar information can predict infection before it is apparent to the patient or caregiver. About 65 patients will be enrolled and will wear these devices for 10 days; during that time the information will be recorded, but not available. After completion, information collected immediately before infection will be compared to other times to identify features that predict infections.
