There is limited information on the cost burden associated with follicular lymphoma (FL) and how it compares to other non-Hodgkin lymphoma (NHL) subtypes. We examined the direct medical costs associated with FL and estimated the incremental 3-year cost of FL compared to other NHL subtypes. Using the linked Surveillance, Epidemiology and End Results-Medicare dataset, we identified 16,691 NHL patients aged 66 years or older who were diagnosed with NHL between 2007 and 2013. The mean 3-year cost among the full NHL sample was $120,120 (standard error (SE) 839). The mean 3-year cost per patient was $114,443 (SE 1738) for FL and $121,402 (SE 950) for non-FL subtypes. The incremental 3-year cost of FL compared to non-FL was US$-5458 (95% confidence interval: US$-9325 to US$-1590). Longitudinally, FL was less costly than other NHL subtypes in the first year only, and became more expensive in the second and third years.
