Biology Studies of Hematologic Cancers

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, pre-malignant conditions, 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.

Objective:

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, and molecular 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 conditions, 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: >= 1 year

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.
