Abstract

BACKGROUND: POEMS syndrome is a paraneoplastic syndrome caused by an underlying plasma cell proliferative disease. In this study, we examined the treatment outcomes and role of radiotherapy in the management of POEMS syndrome.

METHODS: In total, 33 patients diagnosed with POEMS syndrome were analyzed. These patients presented with osteosclerotic myeloma (OSM, n = 13), Castleman's disease (CD, n = 4), OSM with CD (n = 10), and vascular endothelial growth factor elevation without gross lesions (VEGFe, n = 6), respectively. The patients were treated by radiotherapy alone (n = 4), chemotherapy alone (n = 16), or a combination thereof (n = 9).

RESULTS: The clinical response rates of radiotherapy, chemotherapy, and radiotherapy plus chemotherapy were 75%, 69%, and 89%, respectively. In addition, the hematologic response rates were 50%, 69%, and 71%, respectively. Among the six patients with limited multiple lesions who underwent radiotherapy, the clinical symptoms were improved in five patients after radiotherapy. The median progression-free survival (PFS) was 51 months, and the median overall survival (OS) was 65 months. In univariate analysis, the administration of chemotherapy was significantly associated with better PFS (p = 0.007) and OS (p = 0.020). In contrast, underlying VEGFe was a significant factor worsening PFS (p = 0.035) and OS (p = 0.008).

CONCLUSIONS: Radiotherapy produces a reliable clinical response and is effective in improving POEMS-associated symptoms that are refractory to chemotherapy in selected patients with clustered or limited multiple lesions that can be covered by single radiation field.
