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

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

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.
