NCT03088150

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.

Outcome Measures

Primary Outcomes (1)

  • Overall survival (OS)

    Counting from the date of randomization to the date of death of the patient or to the last day of follow-up.

    5 years

Secondary Outcomes (2)

  • Disease free survival

    5 years

  • Time to progression

    5 years

Study Arms (2)

Surgical resection

ACTIVE COMPARATOR

Patients included will undergo resection of hepatic metastases, allowing thermal ablation for additional unresectable lesions.

Procedure: Surgical resection

Thermal ablation

EXPERIMENTAL

Patients included will undergo ultrasound guided thermal ablation of hepatic metastases, allowing resection for additional unablatable lesions.

Procedure: Thermal ablation

Interventions

Patients will undergo either radiofrequency ablation (RFA) or microwave ablation (MWA).

Also known as: Radiofrequency ablation, RFA, Microwave ablation, MWA
Thermal ablation

In case of randomization to surgical resection, the surgeon will remove all target lesions as well as all additional unablatable lesions.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

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;
