Brief Summary
The primary objective is to prove non-inferiority of thermal ablation compared to hepatic resection in patients with at least one resectable and ablatable colorectal liver metastases (≤3cm) and no extrahepatic disease.

Study Arms (2)
Surgical resection
ACTIVE COMPARATORPatients included will undergo resection of hepatic metastases, allowing thermal ablation for additional unresectable lesions.
Thermal ablation
EXPERIMENTALPatients included will undergo ultrasound guided thermal ablation of hepatic metastases, allowing resection for additional unablatable lesions.
Interventions
Patients will undergo either radiofrequency ablation (RFA) or microwave ablation (MWA).
In case of randomization to surgical resection, the surgeon will remove all target lesions as well as all additional unablatable lesions.
Eligibility Criteria
You may qualify if:
- At least one CRLM size ≤ 3 cm eligible for both surgical resection and thermal ablation (target lesions);
- Additional unresectable CRLM should be ≤ 3 cm and ablatable (unresectable lesions);
- Additional unablatable CRLM should be resectable (unablatable lesions);
- Maximum number of CRLM 10;
- Resectability and ablatability should be re-confirmed intra-operatively by US plus full exploration for hepatic, peritoneal and regional lymph node metastases;
- ASA 1-3.
You may not qualify if:
- No target lesions suitable for both resection and ablation;
- Radical treatment unfeasible or unsafe (e.g. insufficient FLR);
- The presence of extrahepatic nodal or non-nodal metastases;
- Immunotherapy or chemotherapy ≤ 6 weeks prior to the procedure;
