Liver resection remains a gold standard for colorectal liver metastases, providing critical data for patient selection and surgical outcomes.

• 90-day mortality rate is under 5% across most groups, signaling low operative risk.
• One-year overall survival exceeds 85% for most subgroups, but drops to 78% for patients with 10 or more metastases.

Timely assessment of these benchmarks will guide surgical decision-making against emerging alternatives like thermal ablation and transplantation.

• Five-year overall survival rates are: ≥45% for solitary synchronous, ≥58% for solitary metachronous metastases; ≥28% for more than 3 metastases.
