Daratumumab plus lenalidomide and dexamethasone for relapsed POEMS syndrome with bone plasmacytoma harboring 17p deletion
International journal of hematology(2022)
摘要
The standard therapies for polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes (POEMS) syndrome are radiation therapy, high-dose chemotherapy followed by autologous stem cell transplantation, and lenalidomide combined with dexamethasone. Daratumumab was reported to be effective for treatment-naive and relapsed POEMS syndrome, but treatment options for relapsed POEMS syndrome with poor prognostic factors or cytogenetic abnormalities have not been established due to a lack of studies in these patients. Here, we describe a case of relapsed POEMS syndrome with bone plasmacytoma harboring a newly detected 17p deletion after high-dose chemotherapy followed by autologous stem cell transplantation and radiation therapy in a male patient. He was successfully treated with daratumumab plus lenalidomide and dexamethasone (Dara-Rd). Dara-Rd could be effective in relapsed POEMS syndrome with 17p deletion, which is known as a poor cytogenetic abnormality in multiple myeloma. This report may broaden the application of Dara-Rd for POEMS syndrome.
