Active clinical trials for "Leukemia, Lymphoid"

Acute lymphoblastic leukemia (ALL) accounts for about 20% of adult leukemias. Treatment results in adult ALL have lagged behind the improvements achieved in the pediatric population. A modified version of the Dana Farber Cancer Institute pediatric protocol is used to treat adult patients with ALL. The results seem to be superior to those reported with other adult protocols. However, there is limited data on the impact of such intensified approaches and resulting toxicities on the quality of life (QOL) of these survivors. Identifying important factors affecting the QOL may permit attempts at early interventions and may help to further modify the regimen and mitigate these adverse effects on QOL. This study is evaluating the quality of life of long term survivors of adult ALL. It involves the patients filling out several questionnaires that are well-validated measures assessing various QOL issues of concern to these patients. The following questionnaires are used in this study: EORTC QLQ C30 to assess global health and major health domains Brief Pain Inventory (BPI) Personal Health Questionnaire (PHQ9) to assess psychosocial distress Functional Assessment of Cancer Therapy (FACT) Fatigue Questionnaire Peripheral Neuropathy Questionnaire The data obtained from the questionnaires will be analyzed and the various domains of health will be quantified.

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. PURPOSE: This research study is studying biomarkers in blood and bone marrow samples from patients with acute lymphoblastic leukemia.

The aim of this study was to investigate the occurrences of respiratory symptoms risk factors and abnormalities in lung function in young children (3-6 years old) with hemato-oncologic diseases at presentation (before treatment) and up to 3 years follow-up (study period).

This clinical trial is looking at brain function in young patients receiving methotrexate for acute lymphoblastic leukemia. Learning about the long-term effects of methotrexate on brain function may help doctors plan cancer treatment.

RATIONALE: Cancer therapies may affect the ability of a child's brain and central nervous system to function normally. Learning to identify which patients will develop complications may improve the ability of doctors to plan cancer treatment and improve patient quality of life. PURPOSE: This clinical trial is studying neurobehavioral changes in children who have received steroid therapy or intrathecal therapy for acute lymphoblastic leukemia.

The aim of this study is to evaluate the impact of Ibrutinib monotherapy in the QoL of subjects with Chronic Lymphocytic Leukemia (CLL) based in European Quality of Life 5 Dimensions (EQ-5D) and FACIT- fatigue questionnaires assessment from baseline to 1 year of treatment in Argentinian routine clinical practice.

The objective of the study is to describe the current epidemiology, treatment patterns, outcomes and healthcare resource use of adult patients diagnosed with relapsed/refractory (R/R) B-cell ALL and de novo AML in 4 Latin American countries.

Improved understanding of the long-time healthcare utilisation of childhood cancer survivors is relevant as it can be seen as a proxy for the population's morbidity. The investigators will conduct a historic population-based matched cohort study using Danish nationwide registry data. Eligible children are children 1.0-17.9 years diagnosed with Acute lymphoblastic leukaemia (ALL) in Denmark from 1994 till 2016. The primary outcome is yearly contact rates to primary healthcare.

High-dose methotrexate therapy (HDMTX) is an important part of treatment of childhood acute lymphoblastic leukemia (ALL). HDMTX would be improved substantially if it were possible to predict the clearance of MTX for each patient and use this to tailor an individualized dosing of the drug. However, only about 3.7, 0.2, and 2% of the inter-individual variation in MTX clearance is explained by age, gender and ancestry, respectively. Genetic variation seems to explain about 10% of this difference, and SNPs in genes encoding transporter proteins (e.g. organic anion transporter 1B1 (OATP1B1) and reduced folate carrier (RFC)) are suggested to have a particular large impact. A serious limitation to the applicability of SNPs in prediction of MTX pharmacokinetics, however, is the substantial intra-individual variation in MTX clearance. The intra-individual variation in MTX clearance is related to renal function but a large amount of a HDMTX dose also enters the liver, where it is metabolized to 7-hydroxy MTX and probably also undergoes enterohepatic circulation. Thus, the aim of this study is to determine the role of the liver and renal function in MTX pharmacokinetics, and evaluate the predictive potential of pharmacogenetic (e.g. the rfc SNP) and pharmacokinetic parameters of MTX elimination during HDMTX.

RATIONALE: Studying samples of 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 predict how patients will respond to treatment. PURPOSE: This research study is studying biomarkers in bone marrow samples from patients with T-cell acute lymphoblastic leukemia.
