93,000 patients studied: what decades of data reveal about carcinoid cancer survival
NCT ID NCT07317713
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at nearly 94,000 people diagnosed with gastrointestinal carcinoid tumors between 2000 and 2022. Researchers used a large cancer database to calculate how many patients died from their tumor compared to the general population. The goal was to fill gaps in knowledge about long-term survival for these rare, slow-growing cancers.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this research could help doctors better predict survival and tailor follow-up for people with gastrointestinal carcinoid tumors.
- What could go wrong
- This is an observational study using existing data, not a treatment trial. It cannot prove what causes better or worse outcomes, only highlight patterns.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The inclusion criteria involved all patients with primary malignant GI carcinoid tumor diagnosed between 2000 and 2022 with sequence number 0 or 1. Sequence 0 indicated the patient had only one cancer record while sequence 1 indicated the patient may had developed many cancer records following the first one. In addition, the tumors were restricted to malignant behavior codes (ICD-O-3 Code 3).
