Mixed monoclonal cryoglobulinemia and monoclonal rheumatoid factor cross‐reactive idiotypes as predictive factors for the development of lymphoma in primary Sjögren's syndrome

Abstract

The determination of MMC can be used as a laboratory predictive factor for lymphoma development in primary SS. CRIs 17109 and G-6 may also be used to predict lymphoma development, especially when the monoclonal component is absent.
