Neuroendocrine Tumors of the Appendix Are Probably Harmless Neoplasms

#1484

Introduction: Appendiceal neuroendocrine tumors (aNETs) have a 5-year survival rate between 74% and 95% according to recent data from Cancer Registry of Norway and the United States, respectively. However, in the daily clinical practice one almost never encounters patients suffering from aNETs with distant metastasis or dying of the disease.

Aim(s): In order to resolve this contradiction, we performed a systematic search in PubMed.

Materials and methods: Systematic search was carried out using key words “appendix or appendiceal”, “carcinoid or neuroendocrine tumors”, “survival” and “registry or register”. We accessed the row data from Surveillance, Epidemiology and End Results Program (SEER) and received recent data from Cancer Registry of Norway (CRN).
