AB  - Background/Aim: The aim of this study was to present the clinical characteristics, natural history and survival outcomes of primary gastrointestinal non-Hodgkin lymphomas (PGINHL) in the pediatric population. Patients and Methods: Surveillance, Epidemiology, and End Results (SEER) database was queried for patients aged 0 to 19 years with PGINHL between 1973 and 2014. Results: A total of 452 cases were identified [mean age 11.0 (±5.1)] years, whites 84.1%, males (76.5%). The majority of tumors were noted in the small bowel (SB) (47.6%), followed by large bowel (LB) (28.5%) and the stomach (10.0%). Overall, the most common histological subtype was Burkitt lymphoma (51.8%), followed by diffuse large B-cell lymphoma (DLBCL) (26.1%). Mean overall survival (OS) of the entire cohort was 33,33 years with a 5-yr, 10-yr and 30-yr survival rate of 86%, 86% and 79%, respectively. Large bowel tumors had the best long-term survival rates whereas; gastric tumors had the worst with 30-yr survival rate 84% and 74%, respectively. Overall, 328 (72.6%) patients received surgery. No significant survival difference was noted between patients who underwent surgery and those who did not. Conclusion: This study presents the largest dataset of pediatric PGINHL and describes the clinical features and outcomes of these patients in addition to summarizing the literature.
