Biology Studies of Hematologic Cancers

2015-02-24 18:01:44 | BioPortfolio

Summary

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 birth 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.)

Description

Background

Laboratory-based investigations have contributed to an improved understanding of pathophysiology and to the development of new therapies for hematologic malignancies.

The aim of this protocol is to facilitate biologic study of leukemias, myelodysplastic syndromes, lymphomas, and other blood disorders.

This is a sample acquisition protocol for targeted study of hematologic malignancies by a collaborative network of NIH investigators from multiple Institutes/Centers.

Objectives

This biology protocol is designed to allow sample acquisition for use in the study of hematologic malignancies. A variety of laboratory investigations designed to support NIH translational trials; to apply new methodologies in the study of cellular, molecular, genetic, and genomic biology; to probe for new therapeutic targets; and to develop new treatment approaches will be performed.

Eligibility

Diagnosis of any hematologic malignancy or pre-malignant blood disorder, including but not restricted to the following: Acute Lymphocytic Leukemia (ALL), Acute Myelogenous Leukemia (AML), Myelodysplastic Syndrome (MDS), Chronic Myelogenous Leukemia (CML), Juvenile Myelomonocytic Leukemia (JMML, J-CML), Non-Hodgkin s Lymphoma (NHL), Hodgkin s Disease

Tumor tissue that has been previously collected and is available for study or that can be collected with minimal additional risk to the subject during sampling required for routine patient care.

Patient age: birth to 75 years.

Design

Biologic assays relevant to the investigation of hematologic malignancies will be performed in an exploratory fashion, some studies are developmental, i.e., assay design in support of current or planned CC clinical trials. Others are standard assays that will be applied in attempt to identify new targets or test new therapeutic approaches.

Medical and Biotech [MESH] Definitions

A pyrimidine nucleoside analog that is used mainly in the treatment of leukemia, especially acute non-lymphoblastic leukemia. Cytarabine is an antimetabolite antineoplastic agent that inhibits the synthesis of DNA. Its actions are specific for the S phase of the cell cycle. It also has antiviral and immunosuppressant properties. (From Martindale, The Extra Pharmacopoeia, 30th ed, p472)

Enzyme that is a major constituent of kidney brush-border membranes and is also present to a lesser degree in the brain and other tissues. It preferentially catalyzes cleavage at the amino group of hydrophobic residues of the B-chain of insulin as well as opioid peptides and other biologically active peptides. The enzyme is inhibited primarily by EDTA, phosphoramidon, and thiorphan and is reactivated by zinc. Neprilysin is identical to common acute lymphoblastic leukemia antigen (CALLA Antigen), an important marker in the diagnosis of human acute lymphocytic leukemia. There is no relationship with CALLA PLANT.

A leukemia/lymphoma found predominately in children and adolescents and characterized by a high number of lymphoblasts and solid tumor lesions. Frequent sites involve LYMPH NODES, skin, and bones. It most commonly presents as leukemia.

A rare acute myeloid leukemia characterized by abnormal EOSINOPHILS in the bone marrow.

An acute myeloid leukemia in which abnormal PROMYELOCYTES predominate. It is frequently associated with DISSEMINATED INTRAVASCULAR COAGULATION.
