Survey of monoclonal gammopathy in western France: incidence and unexpected high frequency of IgM.

摘要

The class distribution of 4193 monoclonal gammopathies (MG), detected over approximately 10 years in western France (WF), was compared to that established by a compilation of twenty-seven series from the literature. Several points emerged from this study: the incidence of the light chain MG (4.8%) was slightly lower than commonly observed (6.0%), the number of double MG higher (4.2%) than elsewhere (1-3%) and the IgM-MG much more frequent (33.0%) than anywhere else (16.2%).
