Background As of 2013, more than 550,000 people are living with non-Hodgkin lymphoma (NHL). Patients and Methods We undertook a large Surveillance Epidemiology and End Results (SEER) based analysis to describe outcome disparities in different subgroups of aggressive T-cell and B-cell NHL patients, with a focus on various ethnicities. Results The final analysis included 7662 patients with T-cell and 84,910 with B-cell NHL. Survival analysis revealed that male sex and increasing age were independent predictors of worse overall survival (OS; P <.001). For aggressive T-cell NHL, there was no significant improvement in median OS between 1973 and 2011 (P =.081), and ethnic minorities (Asians, Hispanics, and African Americans) had significantly worse OS than whites (P <.001). There were similar trends for age, sex, and race for diffuse large B-cell NHL, but a significant improvement in median OS was seen over time (P <.001). Conclusion These results are the first to elicit outcomes in a broad classification of ethnic minorities and underscore the urgency for development of novel therapeutics, especially in T-cell NHL. In addition, in-depth studies of disease biology and health care utilization are required for better triage of health care resources, especially for ethnic minorities.
