Brief Summary
Multiple articles report that thermal ablation is a safe and effective treatment for unresectable colorectal liver metastases (CRLM) ≤3cm. However efficacy of thermal ablation decreases with increasing lesion size. Guidelines state that thermal ablation is the preferred option for unresectable CRLM ≤3cm and stereotactic body radiotherapy (SBRT) when thermal ablation is not possible. It remains uncertain what local treatment method should be recommended for unresectable CRLM of 3-5cm.

Eligibility Criteria
You may qualify if:
- unresectable CRLM size 3-5 cm eligible for both MWA and SBRT (target lesions);
- Additional CRLM are allowed if considered either resectable or ablatable and \<3cm
- No or limited extrahepatic disease (1 extrahepatic lesion is allowed, not including positive para-aortal lymph nodes, celiac lymph nodes, adrenal metastases, pleural carcinomatosis or peritoneal carcinomatosis);
- For subjects with liver only disease the maximum number of CRLM is 10; for subjects with limited extrahepatic disease the maximum number of CRLM is 5;
- Prior focal liver treatment is allowed
- Subjects without prior focal liver treatment should be either unsuitable for 1st line chemotherapy or have progressed under/after 1st-line chemotherapy;
- Subjects with recurrent (either local or distant-hepatic) CRLM after previous focal treatment should be unsuitable for (further) systemic therapy (further downsizing or conversion to resectable disease improbable).
You may not qualify if:
- Compromised liver function (e.g. signs of portal hypertension, INR \> 1,5 without use of anticoagulants, ascites);
- Pregnant or breast-feeding subjects;
- Immunotherapy ≤ 6 weeks prior to the procedure;
- Chemotherapy ≤ 6 weeks prior to the procedure;
- Severe allergy to contrast media not controlled with premedication.
