The impact of socioeconomic disparities on the use of upfront autologous stem cell transplantation for mantle cell lymphoma.

Using the National Cancer Database, we identified 10,290 patients with newly diagnosed mantle cell lymphoma (MCL) treated with chemotherapy with or without upfront autologous stem cell transplantation (ASCT).

On multivariable analysis, age, comorbidity index, insurance type, the transition of care, facility type, distance to facility, and diagnosis year were predictive for ASCT use. ASCT use was associated with improved 5-year overall survival in younger (82% vs. 64%,
