The cause of blood and bone marrow cancers is poorly understood; however, most research focuses on how cancer cells grow and develop. Because the causes of these cancers are unknown, current treatments may be unnecessarily harsh and often do not provide a cure. Identifying the causes of blood cancers would allow for the development of treatments that are more likely to provide a cure. To find the causes of blood and bone marrow cancers, we will look for specific cancer cell abnormalities that are responsible for cancer cell growth. We will then look to see if drugs that can reverse these abnormalities can kill cancer cells.

Inclusion Criteria:

• Suspected or confirmed diagnosis of AL, LPD, MDS, or MPD
• Male or female of all ages
• Willing and able to sign informed consent
• Willing guardian consent for participants under 18 years of age

Exclusion Criteria:

• No suspected or confirmed diagnosis of acute leukemias (AL), lymphoproliferative disorders (LPD), myelodysplastic syndromes (MDS), or myeloproliferative diseases (MPD)

Patients of any age with a diagnosis or suspected diagnosis of a blood or bone marrow cancer may be a part of this study. The provider who will perform the blood draw, bone marrow aspirate, or biopsy as part of the patient's routine care will identify possible participants from their clinic schedule or patient list, give them information about what would be involved in participating in the study including possible risks, and ask if they are interested in participating.
