Diagnostic Study of Gene Alterations in Patients With Acute Myeloid Leukemia
LeukemiaRATIONALE: Diagnostic procedures, such as genetic testing, may improve the ability to detect acute myeloid leukemia and determine the extent of disease. PURPOSE: Diagnostic study to try to detect changes in the genes of patients who have acute myeloid leukemia.

Accuracy Testing of the Chromosomal Aberration and Gene Mutation Markers of the AMLProfiler
Acute Myeloid Leukemia (AML)Acute Promyelocytic Leukemia (APL)1 moreThis clinical study will demonstrate the accuracy of the chromosomal aberration and gene mutation markers of the AMLProfiler molecular diagnostic assay and generate clinical performance data to support a Pre-Market Approval (PMA) submission to the Food and Drug Administration for in vitro diagnostic use within the United States of America. The objective is to demonstrate the positive and negative percent agreement of each marker by comparing AMLProfiler results from multiple clinical participating sites with data generated using a laboratory developed bi-directional sequencing method generated at the molecular diagnostic reference lab. The AMLProfiler assay is a qualitative in vitro diagnostic test for the detection of AML or APL specific chromosomal aberrations (specific recurrent translocations and inversions), as well as expression of specific genetic markers in RNA extracted from bone marrow aspirates of patients with Acute Myeloid Leukemia.

Chronic Myelod Leukemia Registry at Asan Medical Center
LeukemiaChronic Myeloid6 moreThe investigators would like to propose a prospective longitudinal observational cohort study for patients who will be diagnosed and/or treated for chronic myeloid leukemia at Asan Medical Center, Seoul, Korea, to use the acquired data for fundamentals of other retrospective analysis.

Maintenance Therapy With Histamine Dihydrochloride and Interleukin-2 in Adult Acute Myeloid Leukemia...
Acute Myeloid LeukemiaThis is a non-interventional multi-center study (NIS) in adult patients with AML in first complete remission with measurable minimal residual disease (MRD). Patients are eligible when gene status was already determined for previous induction and consolidation therapy of AML and showed carrier of NPM1, CBFβ-MYH11, or MLL-AF9 mutation. The study objective is to observe the impact of pre-emptive therapy with histamine dihydrochloride (HDC) and interleukin-2 (IL-2) with regard to assess leukemia-free survival/time to relapse and to monitor MRD level trend over time. HDC and IL-2 are approved drugs for AML patients in first complete remission. Therapy is administered for 10 treatment cycles as outlined in the Summary of Product Characteristics.

Study of Periodontitis and Blood Stream Infection in AML Patients Receiving Chemotherapy
Acute Myeloid LeukemiaThis is a prospective, observational study to establish the connection between periodontitis and BSI in AML patients planning to receive intensive chemotherapy.

Genome, Proteome and Tissue Microarray in Childhood Acute Leukemia
LeukemiaWe will study gene and protein expression in leukemia cells of children diagnosed with acute leukemia. We hope to identify genes or proteins which can help us grade leukemia at diagnosis in order to: (a) develop better means of diagnosis and (b) more accurately choose the best therapy for each patient.

Allogeneic Transplantation for Patients With Acute Leukemia or Chronic Myelogenous Leukemia (CML)...
LeukemiaLymphocytic7 moreThe purpose of the study is to evaluate the overall and disease free survival of recipients who have received G-CSF mobilized stem cells from HLA matched sibling donors.

Acute Lymphoblastic Leukemia Registry at Asan Medical Center
LeukemiaAcute Lymphoblastic9 moreThe investigators would like to propose a prospective longitudinal observational cohort study for patients who will be diagnosed and/or treated for acute lymphoblastic leukemia at Asan Medical Center, Seoul, Korea, to use the acquired data for fundamentals of other retrospective analysis.

Discontinuation of Imatinib Mesylate in Patients With Chronic-Phase Chronic Myeloid Leukemia Previously...
Chronic Myeloid LeukemiaTo investigate whether patients with chronic-phase chronic myeloid leukemia (CP-CML) previously treated with interferon-alpha (IFN) and presently on a tyrosine kinase inhibitor (TKI) (imatinib mesylate, dasatinib, or nilotinib) with achievement of a complete cytogenetic and at least a major molecular remission, are able to discontinue therapy and maintain a durable remission. Relapse-free survival (RFS) rate at 1 year after discontinuation of TKI will be the measurement of this objective.
