Abstract
POEMS syndrome is an acronym for polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes. It is a rare paraneoplastic disorder related to plasma cell neoplasm. However, its pathophysiology has not yet been clearly elucidated. The production of pro-inflammatory cytokines is thought to play an important role in the pathogenesis of POEMS syndrome. Vascular endothelial growth factor level reflects disease activity, which is helpful for the diagnosis and evaluation of treatment response. Conventional agents such as corticosteroids and melphalan are effective and safe combination regimens. Autologous hematopoietic stem cell transplantation is another option for high-risk transplant-eligible patients. Radiotherapy is effective in patients with localized lesions. The anti-myeloma agents lenalidomide, thalidomide, and bortezomib have shown good treatment outcomes for POEMS syndrome; however, large-scale studies with long-term follow-up are required. Early identification and active treatment can improve the outcomes of POEMS syndrome patients.
