The c-fms proto-oncogene product, which is the receptor for the macrophage colony-stimulating factor CSF-1, is always found expressed in acute myeloid leukemia cells, irrespective of their stage of differentiation according to the FAB classification (Dubreuil P, Torrès H, Courcoul M, Birg F, Mannoni P. Blood 1988;72:1081-1085). We have extended this study and looked for c-fms expression in poorly differentiated myeloid leukemias, in a series of acute leukemias of either T or B origin and in biphenotypic leukemias. We now report that expression of c-fms is still related to the myeloid origin of the leukemic proliferation, but that it can also be found in some acute leukemias presenting clonal rearrangements of the T cell receptor gene. Thus expression of the c-fms/CSF-1 receptor may not be exclusively a marker for myeloid proliferations.

UI MeSH Term Description Entries
D007938 Leukemia A progressive, malignant disease of the blood-forming organs, characterized by distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemias were originally termed acute or chronic based on life expectancy but now are classified according to cellular maturity. Acute leukemias consist of predominately immature cells; chronic leukemias are composed of more mature cells.

D001752 Blast Crisis An advanced phase of chronic myelogenous leukemia, characterized by a rapid increase in the proportion of immature white blood cells (blasts) in the blood and bone marrow to greater than 30%.

D002051 Burkitt Lymphoma A form of undifferentiated malignant LYMPHOMA usually found in central Africa, but also reported in other parts of the world. It is commonly manifested as a large osteolytic lesion in the jaw or as an abdominal mass. B-cell antigens are expressed on the immature cells that make up the tumor in virtually all cases of Burkitt lymphoma. The Epstein-Barr virus (HERPESVIRUS 4, HUMAN) has been isolated from Burkitt lymphoma cases in Africa and it is implicated as the causative agent in these cases; however, most non-African cases are EBV-negative.
