Clinicopathological Features, Treatment Strategy, and Prognosis of Primary Non-Hodgkin’s Lymphoma of the Duodenum: A SEER Database Analysis

Clinicopathological Features, Treatment Strategy, and Prognosis of Primary Non-Hodgkin’s Lymphoma of the Duodenum: A SEER Database Analysis: Objective. Primary duodenum lymphoma (PDL) is extremely rare with limited data available in the literature. In this study, we sought to describe clinical features and identify factors affecting survival in patients with PDL using a large population cohort. Methods. The Surveillance, Epidemiology, and End Results (SEER) database was queried from 1998 to 2015. Results. A total of 1060 cases of PDLs were identified. Clinicopathological features as well as survival data of PDLs were analyzed and compared with 10573 primary gastric lymphomas (PGLs) and 3239 primary small intestinal lymphomas (PSILs) from the SEER database. PDL patients were younger in age (60.96 ± 15.205), and the proportion of stage I (53.21%) was higher in Ann Arbor staging. The proportion of PDLs treated by surgery (8.68%) is the lowest among PDLs, PGLs, and PSILs. The DSS of PDLs were significantly better than those of PGLs and PSILs, respectively (10-year survival rate: 21.24% vs. 20.40%, ; 10-year survival rate: 21.24% vs. 16.79%, ). Age, gender, Ann Arbor staging, and histological type were regarded as independent prognostic factor for the DSS by multivariate analysis (all ). Patients with
