Monoclonal gammopathy in patients with chronic and acute myeloid leukemia

Abstract

Monoclonal IgG components were found in the serum of 5 of 40 patients with chronic myelocytic leukemia (12.5%), as well as in 2 of 15 patients with acute myelocytic leukemia (13.3%). These findings may represent an involvement of the lymphoplasmacytic system in myeloproliferative disorders. The significance of this association is discussed.
