A multicentre study on colorectal liver metastases establishes that an intraprocedural minimum ablative margin of at least 5 mm significantly reduces the risk of local disease progression. With data from 400 ablated tumors across various institutions, findings reveal 3-year progression rates drop to below 1% when margins exceed 4.6 mm. The results substantiate the proposed margin as the standard for achieving superior clinical results during thermal ablation procedures.
