A recent study examined the varying survival rates among US racial/ethnic patient groups with peripheral T-cell lymphoma subtypes.1

Researchers, based at the University of Washington School of Medicine, selected patients age 15 years or older. Approximately 13 107 patients with peripheral T-cell lymphoma (PTCL) were identified in the Surveillance, Epidemiology, and End Results (SEER) registries and were categorized by race/ethnicity.

The researchers categorized the patients as non-Hispanic white, black, Hispanic white, Asian/Pacific Islander, or American Indian/Alaskan native. SEER follow-up data (Cox regression) was used to estimate survival rate.

The annual incidence of PTCL was found to be greatest in the black group. Whites showed a lower incidence of PTCL not otherwise specified (PTCL-NOS), adult T-cell leukemia/lymphoma (ATLL), and anaplastic large-cell lymphoma, but a higher rate of angioimmunoblastic T-cell lymphoma (AITL) compared with blacks.

Both Asians/Pacific Islanders and Hispanics displayed higher incidence of AITL and NK-cell leukemia (ENKCL) compared to whites. Native Americans displayed the lowest annual PTCL incidence of all groups.

Survival rates varied by racial/ethnic group, and blacks showed a lower survival for most peripheral T-cell lymphoma subtypes.

Data from this study appeared in the Journal of Clinical Oncology.
