New study could map best surgical path for colorectal liver metastases
NCT ID NCT07564284
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.

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.

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
