More frequent IgD and reduced CD200 expression in Chinese patients younger than 50 years old with multiple myeloma: a multicenter analysis.

We retrospectively analyzed the presenting features and survival of 194 newly diagnosed patients with multiple myeloma in the People's Republic of China. Compared with older patients, younger patients had a higher percentage of IgD isotype, lower percentage of International Staging System Stage 3 disease, higher albumin level, and lower frequency of high β2-microglobulin and CD200 expression. There was no difference in sex, Durie-Salmon stage, bone lesion degree, creatinine, lactate dehydrogenase, fluorescence in situ hybridization, and expression of other antigens.
