ClinConnect Summary

This clinical trial, titled "Circulating Tumor DNA Guided Adjuvant Chemotherapy for Colon Cancer," is investigating how circulating tumor DNA (ctDNA) can help doctors decide the best chemotherapy treatment for patients with colon cancer after surgery. The focus is on understanding whether some patients with lower-risk colon cancer can receive less chemotherapy without affecting their chances of survival. The study also looks at how ctDNA levels can indicate the risk of cancer returning, which can help tailor treatment plans.

To be eligible for this trial, participants must be between 18 and 75 years old and have a specific type of colon cancer confirmed by a doctor. They should have either stage II colon cancer with certain high-risk features or stage III colon cancer without spread to other parts of the body. Patients will be randomly assigned to different treatment schedules based on their ctDNA results. Throughout the trial, participants can expect regular monitoring and support from the medical team as they receive their assigned treatments. It's important to note that the trial is still recruiting participants, and those interested should discuss it with their healthcare provider to learn more.
