Background: Therapy-related acute myeloid leukemia (tAML) is a serious complication in patients with Non-Hodgkin lymphoma (NHL) exposed to chemotherapy or radiation. This large database study aims to quantify the risk of tAML in NHL, and determine the impact of tAML on overall survival (OS) of patients with NHL. Materials and Methods: Patients diagnosed with NHL and de novo AML from 2009 to 2018 were identified from the Surveillance, Epidemiology, and End Results database. Multiple primary standardized incidence ratio (SIR) sessions of the SEER*Stat software were used to calculate SIR and absolute excess risk of tAML. Overall survival (OS) was evaluated using Kaplan Meier curves and compared using log rank tests. Multivariate analysis was used to study the role of each covariate on OS in patients with tAML. Results: The SIR of tAML was 4.89 (95% CI 4.41-5.41), with a higher incidence of tAML observed for ageyears, NHL prior to 2013 and within 5 years of diagnosis, and those who received chemotherapy. NHL patients with tAML had lower OS than those without tAML (5-year OS 59% vs. 13%, p
