Summary of "A novel three-way Philadelphia Variant t(9;22;17)(q34;q11.2;q12) in chronic myeloid leukemia: A case report."

Chronic myeloid leukemia (CML) is a hematologic malignancy associated with increased circulating myeloid cells and platelets in the peripheral blood, with accompanying bone marrow hyperplasia. The Philadelphia chromosome, t(9;22)(q34;q11), is present in 95% of CML patients, resulting in constitutive tyrosine kinase activity; however, ~5% of CML patients possess a Philadelphia variant. A novel three-way Philadelphia translocation variant, t(9;22;17)(q34;q11.2;q11.2), was identified in a 54-year old man who presented with leukocytosis, anemia and thrombocytosis that was diagnosed with chronic myeloid leukemia, chronic phase. Cytogenetic analysis by G-banding revealed the presence of a three-way translocation involving the long arms of chromosomes 9, 22 and 17. Fluorescence is situ hybridization utilizing a dual-color fusion probe confirmed the presence of the Bcr-Abl fusion gene.

Medical and Biotech [MESH] Definitions

A myelodysplastic/myeloproliferative disorder characterized by myelodysplasia associated with bone marrow and peripheral blood patterns similar to CHRONIC MYELOID LEUKEMIA, but cytogenetically lacking a PHILADELPHIA CHROMOSOME or bcr/abl fusion gene (GENES, ABL).

The phase of chronic myeloid leukemia following the chronic phase (LEUKEMIA, MYELOID, CHRONIC-PHASE), where there are increased systemic symptoms, worsening cytopenias, and refractory LEUKOCYTOSIS.

Clonal hematopoetic disorder caused by an acquired genetic defect in PLURIPOTENT STEM CELLS. It starts in MYELOID CELLS of the bone marrow, invades the blood and then other organs. The condition progresses from a stable, more indolent, chronic phase (LEUKEMIA, MYELOID, CHRONIC PHASE) lasting up to 7 years, to an advanced phase composed of an accelerated phase (LEUKEMIA, MYELOID, ACCELERATED PHASE) and BLAST CRISIS.

An alkylating agent having a selective immunosuppressive effect on BONE MARROW. It has been used in the palliative treatment of chronic myeloid leukemia (MYELOID LEUKEMIA, CHRONIC), but although symptomatic relief is provided, no permanent remission is brought about. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), busulfan is listed as a known carcinogen.

The initial phase of chronic myeloid leukemia consisting of an relatively indolent period lasting from 4 to 7 years. Patients range from asymptomatic to those exhibiting ANEMIA; SPLENOMEGALY; and increased cell turnover. There are 5% or fewer blast cells in the blood and bone marrow in this phase.
