About this study
Official title: Postoperation Maintenance Therapy for Resectable Liver Metastases of Colorectal Cancer Guided by ctDNA: a Multicenter, Randomized, Controlled, Phase III Clinical Trial.
The goal of this clinical trial is to compare in resectable liver metastases colorectal cancer patients.The main question it aims to answer is to investigate whether the progression-free survival (PFS) of resectable colorectal liver metastasis (CRLM) patients with positive ctDNA after surgery is superior with the combination of adjuvant chemotherapy and maintenance therapy compared to adjuvant chemotherapy alone.
- Being tested

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Colorectal resection surgery.Procedure or surgery
Colorectal cancer radical resection combined with liver metastasis resection or ablation.
FOLFOX chemotherapy regimenDrug
Also called CapeOx chemotherapy regimen
Chemotherapy regimens recommended include oxaliplatin-based CapeOx or FOLFOX regimens, or single-agent 5-FU/LV, capecitabine, or combination with targeted therapy.
CapecitabineDrug
Also called 5-FU/LV
Maintenance therapy is recommended to be continued with low-toxicity drugs such as 5-FU/LV or capecitabine, and may be combined with targeted therapy. Treatment should be discontinued once ctDNA testing is negative.
| Study group | Role | What they receive |
|---|---|---|
| Adjuvant chemotherapy combined with maintenance therapy | Experimental | Not described Receives: Procedure: Colorectal resection surgery.; Drug: FOLFOX chemotherapy regimen; Drug: Capecitabine |
| Single adjuvant chemotherapy | Sham comparator | Not described Receives: Procedure: Colorectal resection surgery.; Drug: FOLFOX chemotherapy regimen |
What is being measured
The primary outcome is the main question the study is designed to answer.
3-years Progression Free Survival
PFS is defined as the time from randomization to the occurrence of any progression or death from any cause.
Measured: 3 years after operation.
5-years Progression Free Survival
PFS is defined as the time from randomization to the occurrence of any progression or death from any cause.
Measured: 5 years after operation.
Secondary outcomes (3)
3-years overall survival
Overall survival is defined as the time from randomization to death from any cause. For patients who are still alive at the time of the final analysis, the date of the last contact will be recorded.
Measured: 3 years after operation.
5-years overall survival
Overall survival is defined as the time from randomization to death from any cause. For patients who are still alive at the time of the final analysis, the date of the last contact will be recorded.
Measured: 5 years after operation.
Complication
he complications of adjuvant therapy usually refer to the adverse events that occur during or after treatment, including but not limited to chemotherapy-related adverse reactions, radiation therapy-related adverse reactions, and postoperative complications. Specifically, chemotherapy-related adverse reactions may include nausea, vomiting, diarrhea, anemia, and infections; radiation therapy-related adverse reactions may include skin inflammation, nausea, vomiting, diarrhea, fatigue, and dry mouth; postoperative complications may include bleeding, infection, intestinal obstruction, and poor wound healing. Researchers typically record the types, severity, and impact of these complications on treatment to evaluate the safety and tolerability of adjuvant therapy.
Measured: 5 years.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Colorectal resection surgery., FOLFOX chemotherapy regimen and Capecitabine in people with Colorectal Cancer and Liver Metastases, run by Sixth Affiliated Hospital, Sun Yat-sen University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 4 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
3-years Progression Free Survival (time frame: 3 years after operation.). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Apr 2023; AzTrials last refreshed its copy on 8 Nov 2026.
