An observational study of Neuroendocrine Tumors and Small Intestinal NET, run by Laurent BRUNAUD at 2 sites in France.
Trial summary
Digestive NETs are the second most common malignant digestive tumor after adenocarcinoma. The most common gastrointestinal NETs arise from the small intestine. These tumors have a high lymph node and distant metastatic potential (hepatic, pulmonary, etc.). Read more about this study

About this study
Official title: Evaluation of Preoperative Imaging (CT Scan, DOPA-PET and DOTATOC) in Patients With Small Bowel Neuroendocrine Tumors
Digestive NETs are the second most common malignant digestive tumor after adenocarcinoma. The most common gastrointestinal NETs arise from the small intestine. These tumors have a high lymph node and distant metastatic potential (hepatic, pulmonary, etc.). Their management is essentially surgical and the extent of the resection essentially depends on preoperative data from conventional and isotopic imaging.
The goal of surgical resection is to remove the portion of the small intestine carrying the tumour(s) with healthy margins (so-called R0 resection) and affected lymph nodes in the mesentery (lymph node dissection). The extent of lymph node dissection, sometimes significant, exposes you to the risk of short hail with its own complications (malnutrition, diarrhoea, etc.). Consequently, an analysis of the benefits and risks between the interest of an extensive and oncological resection (R0) and the risks of short bowel must be carried out for each patient.
The reference examination to define lymph node involvement is determined by the histological examination of the resected surgical specimen (reference examination). The preoperative evaluation of lymph node extension is done by preoperative abdominal CT scan. However, the preoperative CT scan is not always consistent (sensitivity and specificity) with the pathology data (reference examination). For about 5 years, isotopic imaging (DOPA-PET and DOTATOC) has become feasible and could improve the quality of preoperative evaluation of lymph node extension. Consequently, the aim of this study is to determine the contribution of isotopic imaging (DOPA-PET and DOTATOC) in the preoperative evaluation of lymph node extension.
Read the detailed description
Digestive neuroendocrine tumors (NET) are developed from neuroendocrine cells, of epithelial origin, scattered throughout the digestive tract. These tumors form a heterogeneous group defined according to the site of origin, the cell type affected, the functional character or not, the cell differentiation (morphology), and finally the potential for tumor progression and aggressiveness. Digestive NETs are the second most common malignant digestive tumor after adenocarcinoma. The most common gastrointestinal NETs arise from the small intestine. These tumors have a high lymph node and distant metastatic potential (hepatic, pulmonary, etc.). Their management is essentially surgical and the extent of the resection essentially depends on preoperative data from conventional and isotopic imaging.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Digestive NETs are the second most common malignant digestive tumor after adenocarcinoma. The most common gastrointestinal NETs arise from the small intestine. These tumors have a high lymph node and distant metastatic potential (hepatic, pulmonary, etc.). Their management is essentially surgical and the extent of the resection essentially depends on preoperative data from conventional and isotopic imaging.
The goal of surgical resection is to remove the portion of the small intestine carrying the tumour(s) with healthy margins (so-called R0 resection) and affected lymph nodes in the mesentery (lymph node dissection). The extent of lymph node dissection, sometimes significant, exposes you to the risk of short hail with its own complications (malnutrition, diarrhoea, etc.). Consequently, an analysis of the benefits and risks between the interest of an extensive and oncological resection (R0) and the risks of short bowel must be carried out for each patient.
The reference examination to define lymph node involvement is determined by the histological examination of the resected surgical specimen (reference examination). The preoperative evaluation of lymph node extension is done by preoperative abdominal CT scan.

Questions about this trial
What is this clinical trial studying?
An observational study of Neuroendocrine Tumors and Small Intestinal NET, run by Laurent BRUNAUD at 2 sites in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
mesenteric lymph nodes (time frame: before surgical procedure). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05246319, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Feb 2025.
