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