Collection of Human Samples to Study Hairy Cell and Other Leukemias, and to Develop Recombinant Immunotoxins for Cancer Treatment

Background: \- Researchers who are studying hairy cell leukemia, and how the disease compares with other disorders, are interested in obtaining additional samples from leukemia patients and healthy volunteers. The investigators are particularly interested in samples from individuals who have diseases that can be treated with a new type of drug called immunotoxin, in which an antibody carrying a toxin binds to a cancer cell and allows the toxin to kill the cell. Objectives: \- To collect a variety of clinical samples, including blood, urine, lymph samples, and other tissues, in order to study the samples and develop new treatments for leukemia. Eligibility: \- Individuals 18 years of age and older who have been diagnosed with leukemia or other kinds of blood and lymphatic system cancers, or who are healthy volunteers. Design: * Individuals who have leukemia will be asked to provide blood, bone marrow, urine, and tumor tissue samples as requested by the researchers. Healthy volunteers will provide only blood and urine samples. * No treatment will be given as part of this protocol.

Decoding the Extracellular Vesicles-driven Communication in the Microenvironment of Hairy Cell Leukemia to Improve Patient Care Management

This is a national multi-centre, experimental, cross-sectional, non-profit study.

Hairy Cell Leukemia: Harnessing the Full Power of Extracellular Vesicles to Improve Patient Care Management

Check whether patients with Hairy Cell Leukemia (HCL) of different status (at diagnosis, in complete remission \> 2 years or relapsed requiring therapy) have a 'signature' of altered immunity based on extracellular vesicles (EV)
