Microbiota and Carcinogenesis of Small-intestine Neuroendocrine Tumors

Microbiota and Carcinogenesis of Small-intestine Neuroendocrine Tumors

The aim of the study is to investigate the impact of the microenvironment on tumorigenesis of small intestinal neuroendocrine tumors often located in the terminal ileum, without identified driver mutations.

Inclusion Criteria:

• Patient with one or more small-intestine neuroendocrine tumor with indication of surgery
• Patient with consent for the collection, storage and reuse of data associated with his/her disease
• Age ≥ 18 years at the time of inclusion
• Non-objection statement obtained for participation in the study

Exclusion Criteria:

• Patients with poorly differentiated neuroendocrine carcinoma or NET (neuroendocrine tumors) of non-intestinal origin or mixed tumors (MiNEN)
• Pregnant, parturient or breast-feeding women
• Minors
• Persons deprived of liberty by judicial or administrative decision
• Adults under legal protection (guardianship, curatorship)
