Prognosis after Upfront Radiation Therapy in Plasma Cell Myeloma: Analysis of the National Cancer Data Base

ConclusionsIn this large nationwide cohort, nearly 1 in 5 of newly diagnosed myeloma patients received upfront RT. The association between socio-economic variables like income or insurance status and the use of upfront RT suggests that a delay in diagnosis may lead to severe skeletal complications of myeloma requiring RT. Worse survival with upfront RT may similarly correspond to more advanced disease, but persistent association in sensitivity analyses supports the hypothesis that a presentation with skeletal complications reflects a more aggressive myeloma biology. Further research should aim at disentangling the socio-economic, clinical, and molecular reasons underpinning this association.DisclosuresOlszewski: Genentech: Research Funding; TG Therapeutics: Research Funding; Spectrum Pharmaceuticals: Consultancy, Research Funding.
