Clinical and epidemiological features of intestinal neuroendocrine neoplasms – A hospital-based multicenter retrospective study in China and the SEER database

#3684

Introduction: Intestinal NENs(I-NENs) are neuroendocrine neoplasms in the small intestine, colon, and rectum. I-NENs can be divided into well-differentiated intestinal neuroendocrine tumors (I-NETs) and poorly differentiated intestinal neuroendocrine carcinomas(I-NECs). Long-term clinical epidemiological studies on large samples of I-NENs are rare because I-NENs are rare tumors.

Aim(s): This study aimed to report the clinical and epidemiological features of I-NENs patients.

Materials and methods: I-NENs diagnosed during the period 2001-2010 were identified in a nationwide and multicenter, 10-year retrospective study in China, while cases in the US were screened from the population-based Surveillance, Epidemiology, and End Results (SEER) registry during 2001 and 2010.
