NCT ID NCT07564284

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This observational study follows 200 patients with colorectal cancer whose liver tumors are found at the same time as the primary cancer. Researchers will compare one-step surgery (removing both tumors at once) versus staged operations (bowel first or liver first) to see which approach lets patients complete their full treatment plan. The goal is to create a treatment algorithm that improves outcomes, quality of life, and cost-effectiveness.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could lead to a treatment algorithm that helps doctors choose the best surgical approach for patients with colorectal cancer and liver metastases.
What could go wrong
This is an observational study, not a treatment trial, so it won't directly test a new therapy. Results may not apply to all patients or hospitals.

Participants

About 200 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Patients with synchronous colorectal liver metastases (CRLM) discussed at a hepatobiliary and/or colorectal multidisciplinary team (MDT) meeting at participating Swedish university hospitals. The population includes all patients in whom curative treatment of both the primary colorectal tumor and liver metastases is considered feasible by the MDT, irrespective of WHO performance status, suitability for chemotherapy, prior history of malignancy, or the presence of treatable extrahepatic disease. Patients are identified consecutively at MDT meetings.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age over 18 years * Histologically proven colorectal cancer * Radiological evidence of liver metastases (contrast-enhanced CT or MRI), detected prior to resection of the primary colorectal tumor * Primary colorectal tumor (colon or rectum) in situ at time of inclusion * Discussed at a hepatobiliary and/or colorectal multidisciplinary team (MDT) meeting * Planned curative treatment of both the primary colorectal tumor AND the liver metastases (by resection, ablation, or transplantation) * Planned curative treatment of any extrahepatic disease, if present Exclusion Criteria: * Unable to give informed consent (Studies 4-6 only; opt-out applies to Study 3) * Untreatable extrahepatic metastases at the discretion of the MDT * Not scheduled for curative resection of both the primary tumor and liver metastases * Emergency resection of the primary tumor performed prior to MDT referral
