title: [Analysis of pathological state of benign monoclonal gammopathy by beta 2-microglobulin and CEA].
abstract: In order to obtain the informations concerning benign monoclonal gammopathy (BMG)-related diseases, beta 2-microglobulin (beta 2-m) levels in sera from the patients with BMG were plotted against their serum carcinoembryonic antigen (CEA) levels, and then this figure was divided into the two regions, i.e., A-region (beta 2-m less than 7 mg/l & CEA less than 7 ng/ml) and B-region (beta 2-m greater than or equal to 7 mg/l & CEA greater than or equal to 7 ng/ml). Also, the normal region was expressed as C-region within A-region. In consequence, it was revealed that A-region and B-region mainly consisted of the inflammation and degeneration-related diseases and the tumor-related diseases, respectively.
