Background: Leukapheresis is a procedure to separate and collect white blood cells. It is the first step in a treatment called CAR (chimeric antigen receptor) T-cell therapy. CAR-T therapy may be offered to people when their cancer comes back. The collected T-cells are used to make a special version of T-cells called CARs. Researchers want to collect these cells from people who may become eligible for a CAR T-cell study in the future. Objective: To identify people who have a high likelihood to benefit from CAR T-cell therapy early in their disease course and collect and store a T-cell product. Eligibility: People ages 4-39 with a form of leukemia or lymphoma that has not been cured by standard therapy Design: Participants will be screened with medical history, physical exam, and blood and urine tests. Review of existing MRI, x-ray, pathology specimens/reports or CT images may be done. On this study, participants will have leukapheresis. A needle will be placed into the arm. Blood will be collected and go through a machine. White blood cells will be taken out by the machine. The plasma and red cells will be returned to the participant through a second needle in the other arm. The procedure will take 4-6 hours. Some participants may have a central line (catheter) inserted which is needed to do the leukapheresis procedure, instead of the needles in the arms-especially if they are smaller. For a central line placement, a long thin tube is inserted through a small incision into the main blood vessel leading into the heart that would allow access to the blood to do the leukapheresis procedure. Participants cells will be processed and frozen for future use in a CAR T-cell therapy study.
This is a phase II, open-label, non-randomized, prospective study of haploidentical transplantation using KIR-favorable donors for children with acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) undergoing allogeneic hematopoietic cell transplantation (HCT). The relationship of KIR2DL1 polymorphisms to survival in children with these diseases undergoing any approach to allogeneic HCT during the study time frame will also be determined.
This study will collect tumor samples from people with cancers of the blood, bone marrow, or lymph glands for laboratory study of the biology of these conditions. Such studies contribute to a better understanding of cancer biology and to the development of new treatments. Planned studies include: - Examination of individual cancer cells and to search for differences compared to other types of cancer and normal cells - Examination of the chromosomes and genes in cancer cells and to search for differences compared to other types of cancer and normal cells - Development of sensitive methods to detect small amounts of cancer that remain after treatment - Search for new cancer proteins that might serve as targets for treatment - Investigation of methods to develop cancer vaccines. Patients from >= 1 to 75 years of age with acute lymphocytic leukemia, acute myelogenous leukemia, myelodysplastic syndrome, chronic myelogenous leukemia, juvenile myelomonocytic leukemia, non-Hodgkin's lymphoma, Hodgkin's disease, and other hematologic malignancies may be eligible for this study. Blood or bone marrow samples will be collected when sampling is required for the patient's medical care. Cells from some individuals will be grown in test tubes, establishing cell lines or in animals, establishing xenograft models. (A xenograft is transplantation of cells of one species to another species.)
