Progress of diagnosis and treatment of monoclonal gammopathy of neural significance / 白血病·淋巴瘤

ABSTRACT

Monoclonal gammopathy of neural significance (MGNS) belongs to the category of monoclonal gammopathy of clinically significance. It is an early-stage disease that mainly occurs in peripheral nerves and is not sufficient for the diagnosis of multiple myeloma or lymphoma. MGNS needs to be differentiated from neuropathies due to POEMS syndrome and light-chain amyloidosis; if necessary, nerve biopsy can be performed to clarify the relationship between peripheral nerve symptoms and lymphoplasmacytic disease. Treatment of MGNS is recommended to give intravenous gammaglobulin, plasma exchange and targeted anti-lymphoplasmacytic tumour therapy such as CD20 monoclonal antibody. Early recognition and intervention of MGNS, with multidisciplinary cooperation, will help to reduce the risk of malignancy and the incidence of disability.
