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

The aim of this multicenter randomized crossover design study is to evaluate a sample of 500 boys and girls from public and private schools in the Principality of Asturias, aged between 6 and 12 years, with the objective of determining the level of physical condition, as well as to evaluate the effect of the use of FFP2/N95 face masks during the execution of the ALPHA Fitness battery, and the emotional effects caused by the use of these masks. This is a sample obtained by accessibility, in which the sampling will be stratified by age and academic year.

The purpose of the study is to determine the utility of XCL1 in the prognosis of acute lymphoblastic leukemia.

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.

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about cancer and the development of drug resistance in patients. PURPOSE: This laboratory study is looking at resistance to methotrexate in patients with acute lymphoblastic leukemia in relapse or remission.

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 laboratory study is evaluating how well dactinomycin and vincristine work in treating young patients with cancer. Studying samples of blood and urine in the laboratory from patients with cancer may help doctors learn how dactinomycin and vincristine affect the body and how patients will respond to treatment.

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.

Patients who are being considered for participation in a NCI Pediatric Oncology Branch research study will be screened for eligibility under this protocol. For every NCI research study, patients must meet defined medical criteria in order to ensure the integrity of the research study and to maximize patient safety. Tests and procedures required for determining eligibility depend on the specific study for which the patient is being considered. Some of the more common tests and procedures are: History and physical examination Blood and urine samples for routine laboratory tests and possibly research studies Quality of life assessment questionnaire Magnetic resonance imaging (MRI) scan uses a magnetic field and radio waves to produce pictures of body structures, including tumors Computerized tomography (CT) scan uses radiation to produce multiple detailed pictures of body structures X-rays uses radiation to provide a single picture of a body part Nuclear medicine scans uses a chemical tagged with a radioactive substance to detect tumors, measure kidney or heart function, or monitor the flow of cerebrospinal fluid (fluid that bathes the brain and spinal cord) Electrocardiogram (EKG) uses electrodes placed on the skin to evaluates heart rate and rhythm by measuring electrical impulses from the heart Echocardiogram uses high-frequency sound waves to evaluate heart structure and function Lumbar puncture tests for cancer cells and other substances in cerebrospinal fluid. Involves placing a needle into the lower back between the bones of the spine and withdrawing a fluid sample from the fluid-containing space below the spinal cord Ommaya reservoir surgically implanted catheter inserted into the fluid-filled ventricles of the brain, used to withdraw spinal fluid samples and to give medication Eye examination vision test and eye examination Biopsies removal of a small piece of tissue, by needle or by surgery, for examination under the microscope. An area of skin over the biopsy site is numbed with an anesthetic. For a needle biopsy, a needle is inserted into the tumor, tissue or bone marrow to pull out a small sample. A surgical biopsy may be done in the operating room, clinic, or hospital room, depending on the biopsy location. The tissue or tumor is removed by cutting a small piece of it with a sharp knife or scalpel and the area will be closed with sutures or staples.
