What this trial studies

This observational study aims to explore how the microenvironment, particularly the microbiota, influences the development of small-intestine neuroendocrine tumors, which are often found in the terminal ileum and lack identified driver mutations. Participants will undergo blood and stool sampling to gather data on their microbiota and tumor characteristics. The study seeks to enhance understanding of tumorigenesis in these specific tumors, potentially leading to new insights in treatment approaches.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have one or more small-intestine neuroendocrine tumors and are scheduled for surgery.

Not a fit: Patients with poorly differentiated neuroendocrine carcinoma, non-intestinal NETs, or mixed tumors, as well as pregnant or breastfeeding women, will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the role of microbiota in tumor development, potentially leading to novel therapeutic strategies for patients with small-intestine neuroendocrine tumors.

How similar studies have performed: While the specific approach of examining microbiota in small-intestine neuroendocrine tumors may be novel, similar studies investigating the role of microbiota in other cancers have shown promising results.
