[Successful treatment of POEMS syndrome-associated pulmonary hypertension with lenalidomide and dexamethasone therapy].

POEMS syndrome is often complicated by pulmonary hypertension. The standard therapy for patients with POEMS syndrome is high-dose chemotherapy followed by autologous stem cell transplantation. However, the safety of high-dose chemotherapy for patients complicated with pulmonary hypertension remains unclear, and the optimal therapy for these patients is yet to be establishment. Herein, we report the case of a 54-year-old woman with POEMS syndrome accompanied by pulmonary hypertension. We successfully and safely performed lenalidomide and dexamethasone (Ld) therapy followed by high-dose chemotherapy and autologous stem cell transplantation, which improved her pulmonary hypertension. Thus, Ld can be considered as safe and effective for pulmonary hypertension with POEMS syndrome.
