Summary

The goal of this study is to test better ways to predict if cancer will return after surgery in adults (18+) who have been diagnosed with stage II or III colon cancer.

The main questions it aims to answer are:

* Can computer programs (Artificial Intelligence) and special blood tests give more accurate information about the risk of cancer returning than the methods doctors use today?
* Does combining these new tests help doctors better understand which patients really need chemotherapy and which do not?

Researchers will compare the new computer and blood tests to the standard hospital methods used now to see if the new way is more accurate in predicting the cancer's behavior

Participants will:

* Sign a form saying they agree to take part in the study
* Have their standard surgery to remove the tumor
* Give a few extra teaspoons of blood during their regular, scheduled hospital visits
* Allow researchers to scan and study a small piece of the tumor that was already removed during surgery
* Continue with their normal hospital check-ups for up to five years so researchers can track their health

Blood draw for the laboratory assessment

Study-specific blood samples for ctDNA analysis are collected between three and eleven times per participant, performed exclusively during routine standard-of-care venipunctures to ensure minimal risk and burden.
