AbstractNon-Hodgkin lymphoma (NHL) is one of the most common hematological cancers in the United States. The mortality rate of NHL in the United States is the sixth highest among all cancers. Our cross-sectional study aims to examine the trends and disparity in NHL mortality. We analyzed death certificate data from the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) United States to determine the NHL mortality trends among the U.S. population aged ≥15 years. NHL (ICD-10 C82-85) was listed as the underlying cause of death. Age-adjusted mortality rates (AAMRs) per 100,000 individuals and joinpoint trend analysis were performed to determine the average annual percent change (AAPC) in AAMR trends. From 1999 to 2020, NHL accounted for 457,143 deaths in the United States, of which 54% are men and 46% are women. The NHL AAMR decreased significantly from 10.59 to 6.21 per 100,000 individuals with an AAPC of -2.55. Men had a higher AAMR than women (10.10 vs 6.29 per 100,000 individuals). Whites recorded the highest AAMR (8.43 per 100,000 individuals), followed by Hispanics (6.32 per 100,000 individuals), Blacks (5.71 per 100,000 individuals), American Indians (5.31 per 100,000 individuals), and Asians (5.10 per 100,000 individuals). Those who lived in the Midwest and the rural areas had the highest AAMR at 8.60 and 8.35 per 100,000 individuals respectively. Despite the declining NHL mortality rate, this study calls for targeted intervention to improve outcomes for susceptible individuals affected by NHL.
