Lack of ASCT was associated with inferior rwOS (aHR, 0.59; 95% CI, 0.51\u20130.67). Black patients were less likely to receive ASCT (younger than 65 years: adjusted subdistribution HR [asHR], 0.64; 95% CI, 0.57\u20130.72; 65 years and older: asHR, 0.54; 95% CI, 0.42\u20130.69) and experienced a longer time to transplantation. Medicaid was associated with a lower likelihood of ASCT in patients younger than 65 years (aHR, 0.50; 95% CI, 0.38\u20130.67) and was three times more common among Black than White patients. Among patients who received oncology care, Medicaid expansion was not associated with changes in Medicaid coverage, ASCT receipt, or rwOS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Medicaid was associated with a lower likelihood of ASCT and was more prevalent among Black patients. Reduced receipt of ASCT was linked to inferior survival, contributing to survival disparities. Within this treated cohort, Medicaid expansion did not improve coverage, ASCT receipt, or survival, suggesting that structural barriers beyond insurance persist. Targeted efforts to improve ASCT access among Medicaid\u2010insured patients are needed.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/cncr.70596","type":"journal-article","created":{"date-parts":[[2026,8,28]],"date-time":"2026-08-28T11:00:31Z","timestamp":1787914831000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Racial differences in multiple myeloma survival: Associations with stem cell transplantation, insurance, and Medicaid expansion"],"prefix":"10.1002","volume":"132","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4333-5017","authenticated-orcid":false,"given":"F.
