Cytokine profile in acute myelofibrosis associated with aggressive large granular lymphocyte leukemia.
We report a patient with acute large granular lymphocyte (LGL) leukemia, presenting as acute myelofibrosis (AMF). The leukemic cells were immature T-cells (CD5+, CD7+, CD16-, CD56-, CD57-, and CD41-), had monosomy 7, and secreted large amounts of Transforming Growth Factor-beta 1(TGF-beta 1). The serum levels of interleukins (IL)-2, -2R, -6 and -8 were elevated, while the IL-1 beta, IL-4, and tumor necrosis factor-alpha were normal.
