Introduction: There remains a paucity of literature on survival related to pediatric appendiceal tumors. The purpose of this study was to determine the incidence, surgical management, and survival outcomes of appendiceal tumors in pediatric patients. Methods: The Surveillance, Epidemiology, and End Results (SEER) Registry was analyzed for pediatric appendiceal tumors from 1973 to 2011. Parameters analyzed were: tumor type, surgical management (appendectomy vs. extensive resection), tumor size, and lymph node sampling. Chi-square analysis for categorical and Student's t test for continuous data were used. Results: Overall, 209 patients had an appendiceal tumor, including carcinoid (72%), appendiceal adenocarcinoma (16%), and lymphoma (12%). Patients undergoing appendectomy vs. extensive resection had similar 15-year survival rates (98% vs. 97%; p = 0.875). Appendectomy vs. extensive resection conferred no 15-year survival advantage when patients were stratified by tumor type, including adenocarcinoma (87% vs. 89%; p = 0.791), carcinoid (100% vs. 100%; p = 0.863), and lymphoma (94% vs. 100%; p = 0.639). There was no significant difference in 15-year survival between tumor size groups ≥ 2 and < 2 cm (both 100%) and presence or absence of lymph node sampling (96% and 97%; p = 0.833) for all patients with a carcinoid tumor. Conclusion: Appendectomy may be adequate for pediatric appendiceal tumors. Extensive resection may be of limited utility for optimizing patient survival, placing patient at greater operative risk. Type of Study: Retrospective Prognostic Study. Level of Evidence: III
