Study summary

The goal of this clinical trial is to compare in resectable colorectal cancer liver metastasis patients.The main question it aims to answer is whether the 3-year progression-free survival rate (PFS) of "watching and waiting" is non-inferior to adjuvant chemotherapy in postoperative ctDNA-negative resectable colorectal cancer liver metastasis patients.Participants will undergo ctDNA testing after resection of colorectal cancer liver metastasis, and will be randomly assigned to receive adjuvant chemotherapy or "watching and waiting" treatment strategy. The researchers will compare the outcomes between the two groups to see if the PFS between the two groups is similar.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Both genders are eligible; aged between 18-75 years old; have received chemotherapy;
  2. Patients with liver colorectal cancer who have achieved R0 resection according to MDT evaluation (including patients with metastases treated with ablation therapy that achieved similar R0 resection effects);
  3. Patients with negative ctDNA after surgery;
  4. \<IV and/or performance status score ≤ 2;
  5. Have sufficient understanding of the study and voluntarily sign an form.

Exclusion criteria

Exclusion Criteria:

  1. Patients with distant , including pelvic, ovarian, peritoneal, etc.;
  2. Patients with a history of other ;
  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 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;
  8. Patients with a history of severe mental illness;
  9. Pregnant or lactating women;
  10. Patients with other clinical or laboratory conditions that the investigator deems unsuitable for participation in the trial.
Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Study arms

  • Experimental
    Watching and waiting group

    Watch and Wait strategy is one of the treatment strategies of advanced rectal cancer, which recommends no immediate surgery with close surveillance.

    Procedure: Colorectal cancer resection combined with liver metastasis resection.

  • Active comparator
    Adjuvant chemotherapy group

    Chemotherapy regimens recommended include oxaliplatin-based CapeOx or FOLFOX regimens, or single-agent 5-FU/LV, capecitabine, or combination with targeted therapy.

    Procedure: Colorectal cancer resection combined with liver metastasis resection. · Drug: FOLFOX chemotherapy regimen

Interventions

  • ProcedureColorectal cancer resection combined with liver metastasis resection.

    The preferred surgical approach is resection of the corresponding colon segment with regional lymph node dissection. If conditions permit, synchronous resection of the primary lesion and liver metastases of colorectal cancer can be performed to achieve curative resection.

  • DrugFOLFOX chemotherapy regimen

    Chemotherapy regimens recommended include oxaliplatin-based CapeOx or FOLFOX regimens, or single-agent 5-FU/LV, capecitabine, or combination with targeted therapy.

    Also known as: CapeOx chemotherapy regimen

What researchers measure

Primary outcomes

  1. 3-year progression-free survival

    PFS is defined as the time from randomization to the occurrence of any progression or death from any cause.

    Time frame: 3 years after operation.

  2. 5-year progression-free survival

    PFS is defined as the time from randomization to the occurrence of any progression or death from any cause.

    Time frame: 5 years after operation.

Secondary outcomes

  1. 3-year 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.

    Time frame: 3 years after operation.

  2. 3-year 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.

    Time frame: 5 years after operation.

  3. Complications

    When evaluating the safety and tolerability of adjuvant therapy, researchers typically assess adverse events (AEs) based on their incidence and severity, and then grade them according to the NCI CTCAE version 5.0. NCI CTCAE 5.0 categorizes AEs into 5 grades based on severity, including grade 1 (mild), grade 2 (moderate), grade 3 (severe), grade 4 (life-threatening), and grade 5 (death).

    Time frame: 5 years.
