The proposed study will be an open-label prospective investigation using fresh bone marrow and paired peripheral blood samples obtained from patients with AML starting at the time of diagnosis and including samplings at times of response assessment (CR and NR) continuing through relapse for responders and for other subsequent treatments including salvage therapy after resistance/relapse. Approximately 100 AML patients are expected to be enrolled. There is no extra marrow and blood sampling taken from patients who enroll into this study because we only study their marrow and blood when they undergo such sampling for routine medical needs. The SCNP results will not be used to guide or adjust current, or future, treatment for patients enrolled in this study and they will not be contacted regarding the study results.
