OBJECTIVES: - To provide a mechanism for sample collection and submission for diagnostic review to determine eligibility of patients with suspected leukemia or related hematologic disorders for enrollment on ECOG leukemia clinical trials. - To obtain baseline samples for correlative studies outlined in parent clinical trials. OUTLINE: This is a cohort, multicenter study. Patients submit bone marrow and/or blood samples. The samples are studied to determine patients' eligibility for ECOG leukemia treatment clinical trials. Samples may be stored for future correlative studies related to ECOG treatment clinical trials.
