Official title: ctDNA-guided Adjuvant Chemotherapy in Liver Metastasis of Colorectal Cancer: A Prospective Multicenter Randomized Controlled Clinical Trial

Run by Sixth Affiliated Hospital, Sun Yat-sen University · NCT05815082 · Data updated 2026-11-12

This study is testing if some patients with liver metastasis from colorectal cancer can safely skip chemotherapy after surgery and just be monitored instead.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-75 with resectable colorectal cancer liver metastases who have achieved R0 resection and have negative ctDNA results post-surgery.

Probably not a fit

Patients with distant metastases, severe underlying health conditions, or those who have received other investigational therapies may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to evaluate whether a 'watching and waiting' approach is as effective as adjuvant chemotherapy for patients with resectable colorectal cancer liver metastases who test negative for circulating tumor DNA (ctDNA) after surgery. Participants will be randomly assigned to either receive the FOLFOX chemotherapy regimen or to be monitored without immediate treatment. The primary outcome measured will be the 3-year progression-free survival rate between the two groups. This study seeks to determine if avoiding chemotherapy is a viable option for certain patients post-surgery.

Why it matters

Potential benefit: If successful, this study could provide a less aggressive treatment option for patients with colorectal cancer liver metastases, potentially reducing the side effects associated with chemotherapy.

How similar studies have gone: While there have been studies exploring ctDNA in cancer treatment, this specific approach comparing chemotherapy to observation in this patient population is relatively novel.

Inclusion Criteria:

1. Both genders are eligible; aged between 18-75 years old; have received neoadjuvant chemotherapy;

3. Patients with severe liver, kidney, heart and lung dysfunction, coagulation dysfunction, or serious underlying diseases who cannot tolerate chemotherapy;
4. Patients who are allergic to any component in the study;
5. Patients who have received other tumor-related investigational drug therapy;
6. Patients with severe uncontrolled recurrent infections or other serious uncontrolled concurrent diseases;
7. Patients with other factors that may affect the study results or lead to premature termination of the study, such as alcoholism, drug abuse, other serious diseases that require comprehensive treatment (including mental disorders), and serious abnormal laboratory tests;
