e19070 Background: Peripheral T-cell lymphomas (PTCL) are a rare heterogenous group of lymphomas and modern studies on incidence patterns of PTCL are lacking. Methods: Using the National Program of Cancer registries (NPCR) database, which covers 99% of the US population, we aim to evaluate the incidence of PTCL according to age, race-ethnicity, and gender; and examine trends over time. We identified PTCL using ICD-O-3 codes and evaluated incidence trends from 2001 to 2015. Results: A total of 78722 PTCL cases were identified, the most common were Mycoses fungoides/Sezary syndrome (MF-SS), PTCL Not Otherwise Specified (NOS), and ALK+ Anaplastic Large Cell Lymphoma (ALK+ ALCL). The age-adjusted incidence rate was 2.1 per 100,000. Incidence of PTCL increased with age (6.7/100,000 in 80+years). PTCL was more common in males than females (incidence rate ratio [IRR] of 0.6, p
