Brief Summary
The goal of this observational study is to learn about treatment outcomes, quality of life, and healthcare costs in patients with colorectal cancer who have liver metastases detected at the same time as their primary tumor (synchronous colorectal liver metastases, CRLM). The main questions it aims to answer are: Do patients who undergo simultaneous removal of both the bowel tumor and liver metastases in one operation differ in their ability to complete the intended treatment compared to patients who undergo staged operations (bowel first or liver first)? Does the choice of surgical strategy affect quality of life and healthcare costs? Patients with synchronous CRLM discussed at a multidisciplinary team meeting at participating Swedish university hospitals will be followed prospectively for up to 5 years. Treatment is not influenced by the study - all surgical decisions are made as part of routine clinical care. Patients in the quality-of-life sub-study will complete validated questionnaires (EORTC QLQ-C30, QLQ-LM21, and QLQ-CR29) at multiple time points from diagnosis through 36 months. Healthcare costs and health literacy will also be assessed in parallel sub-studies.

Outcome Measures
Primary Outcomes (1)
Failure to Return to Intended Oncological Treatment (RIOT)
The proportion of patients who do not complete their planned surgical treatment pathway, and the reasons for failure. In staged resections, this most commonly occurs when disease progression during the interval between operations renders the second operation unfeasible.
From date of MDT discussion to completion of intended treatment, assessed up to 24 months.
Secondary Outcomes (9)
Overall Survival
Time frame: 3 and 5 years from diagnosis
Recurrence-Free Survival
3 and 5 years from completion of treatment.
90-Day Mortality
90 days from first surgery.
30-Day Readmission
30 days from each surgical procedure.
Major complications
30 and 90 days from each surgical procedure
- +4 more secondary outcomes
Study Arms (1)
Synchronous colorectal liver metastases
Simultaneous Resection, Bowel-First Staged Resection, Liver-First Staged Resection
Eligibility Criteria
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.
You may qualify if:
- 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
- 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
You may not qualify if:
- 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
