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

A multicenter retrospective observational study among children with type 1 diabetes will be performed. The Objective of this study will be to determine a) the association between the increase in Hba1c in children with type 1 diabetes and confinement due to the COVID 19 pandemic. b) the association between the frequency of patient care during social confinement and the Hba1c values. Different centers from Latin America including Argentina, Peru, Panama, Chile, and Ecuador will participate in this study. Children younger than 17 years with a diagnosis of type 1 diabetes prior to 2018 will be included. Data from the medical records of the participating centers will be collected on the Hb A1c value before and after confinement (6 months completed). The initial (base) value will be taken as a value of HbA1c registered in the patient's Clinical History for the year 2018, 2019, and 2020 pre and post quarantine (Sep-Oct-Nov) 2020, considering compliance with six months of quarantine. Hb A1c should have been performed in the same institution or with the same methods in order to avoid bias.

RATIONALE: Studying samples of blood and bone marrow from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors find better ways to treat cancer. PURPOSE: This laboratory study is looking into genes in samples from younger patients with acute lymphoblastic leukemia (ALL).

Previous findings have shown that a biomarker comprised of the three microRNAs (miRs) miR-451, miR-151-5p and miR-1290 can independently predict precursor B-cell acute lymphoblastic leukemia (B- ALL) patients' risk for relapse when measured in cells from a bone marrow (BM) aspiration taken at diagnosis (Avigad et al., 2016: Genes, Chromosomes & Cancer 55:328-339). Curewize Health recognizes that the development of a minimally invasive blood test for frequent long-term monitoring can greatly benefit pediatric precursor B-ALL patients. Therefore, the current study will investigate the monitoring ability of miR-451, miR-151-5p and miR-1290 measured in blood samples. The study will be performed in two stages: Stage 1-Cross-Sectional Study: Blood samples will be collected from relapsed pediatric B-ALL patients and B-ALL patients in remission. Blood will be collected from each patient in three tubes, for serum, plasma and whole blood analysis, in order to interpret the best blood source for measuring miR-451, miR-151-5p and miR-1290. The level of the miRs in blood will be compared between relapsed B-ALL patients to B-ALL patients in remission. If the Stage 1 Cross-Sectional study is successful, the investigators will continue the clinical trials to the Stage 2 Prospective Monitoring study. Stage 2-Prospective Monitoring Study: Blood will be collected from patients at diagnosis and at routine clinical follow-up. Patients can be up to five years from diagnosis. The source of blood found to be most optimal for measuring the miR levels is Stage 1 will be collected. The final design of the Stage 2 study will be decided after completion of the Stage 1 study.

Treatment outcomes of lymphoblastic lymphoma (LBL) have improved by the use of the regimens for acute lymphoblastic leukemia. Hyper-CVAD is one of the most effective treatments with high remission rate in acute lymphoblastic leukemia (ALL) and LBL. However, the treatment outcome of hyper-CVAD in LBL has reported only in small number of patients from single institution. The investigators conducted this study to evaluate the hyper-CVAD regimen based treatment in LBL.

Nowadays approximately 80% of children and adolescents with acute lymphoblastic leukaemia (ALL) or lymphoblastic lymphoma (LBL) can be cured and become long-term survivors. Avascular osteonecroses (ON) appear as serious side-effect of antileukaemic treatment. Frequently ON are first diagnosed at higher and than irreversible stages (ARCO III, IV). At these advanced stages curative treatment options are not available. Hence ON are associated with considerable morbidity concerning pain and immobility and go along with long-term impairment of quality of life. Therefore early diagnosis of ON in the follow-up of children and young adults with ALL or LBL is a pressing object. Within the prospective multicentric observational OPAL-trial patients at risk (aged 10 years or older) treated according to the clinical trials ALL-BFM(Berlin-Frankfurt-Muenster Study Group), COALL or NHL (Non Hodgkin Lymphoma)-BFM in Germany should be examined with regard to the development of ON. By using a treatment associated, risk orientated assessment and examination incidence, symptoms and the clinical course of ON are investigated. The validity of MRI screening in the early diagnosis of ON in children and young adults is analysed. Systematical investigation of patients under antileukaemic treatment is intended to contribute to risk adapted diagnostic strategies and to serve as data base for the subsequent evaluation of preventive and interventional approaches for the treatment of ON. Long-term objective is the reduction of ON-associated morbidity.

RATIONALE: Collecting and storing samples of tumor tissue, blood, bone marrow, and other body fluids from patients to test in the laboratory and collecting information about the patient's health and treatment may help doctors learn more about cancer and help the study of cancer in the future. Studying these samples in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is collecting and looking at blood and tissue samples in children with newly diagnosed acute lymphoblastic leukemia.

Acute lymphoblastic leukemia , also known as acute lymphocytic leukemia, characterized by the overproduction and accumulation of cancerous, immature white blood cells, known as lymphoblasts, causing damage and death by inhibiting the production of normal cells (such as red and white blood cells and platelets) in the bone marrow and by spreading (infiltrating) to other organs. Acute lymphoblastic leukemia is most common in childhood, with a peak incidence at 2-5 years of age and another peak in old age.

The purpose of this study is to create a software product on the basis of the support technologies for making decisions for the collaboration of the different specialists, the family and the patient himself in the process of physical therapy of children treated for cancer. The basic model of the technology is a qualification model of the state of health and physical limitations, based on data from a survey of 1,000 children treated for cancer. The software product is supposed to be created on the basis of the Splunk system, the key link is a personal office with a two-way login system: for specialists and for patients. The patient introduces the results of self-examination, monitoring and additional surveys in real time, specialists - additional recommendations. To assess the effectiveness of the collaboration based on the software product, a long-term follow-up (at least 3 years) is planned for the participants of the study with repeated examinations at the Medical-Rehabilitation Scientific Center "Russe pole" at least twice a year.

In phase 2 and phase 3 studies, inotuzumab has shown evidence of single agent anti-leukemic activity and proved to be particularly effective in providing a deep response, with an acceptable safety profile. Since 2014 anti-CD22 has been available for compassionate use in Italy. In this non-interventional retrospective study, toxicity, effectiveness and costs assessment data will be collected from patients with ALL, to improve the knowledge about anti-CD22 treatment in clinical practice. Collecting data of patients and analyzing a large unbiased patient-set of patients receiving anti-CD22 immunoconjugates could enlarge our knowledge on therapies engaging CD22
