Could colorectal cancer and diabetes be linked by genes?
NCT ID NCT07648589
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study will follow 200 people with colorectal cancer and healthy controls to explore how genes, blood sugar, and immune responses are connected. Researchers will analyze blood and tissue samples to find shared genetic factors that may influence both cancer and diabetes. The goal is to better understand these links and identify potential markers for personalized care.
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 study could point toward better risk assessment and new treatment targets for colorectal cancer patients with glucose issues.
- What could go wrong
- This is an early observational study, not a treatment trial. It may not lead to direct patient benefits, and results may not apply to all populations.

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 study population consists of adult patients aged 20 to 85 years with newly diagnosed colorectal cancer treated at Chang Gung Memorial Hospital. Participants without pre-existing diabetes mellitus will be enrolled and followed prospectively. Clinical data, blood samples, and available colorectal tissue specimens will be collected for analyses of glucose homeostasis, shared genetic variants, inflammatory biomarkers, and immune cell profiles.
