Radiofrequencyablation (RFA) is a well-establishedmethodforpalliativetherapyofunresectable liver tumors. We use an open orpercutaneousapprooachforthetreatmentofcolorectal liver metastases (CLM).
Clinical data of patients undergoing percutaneous or open RFA for CLM between January 2001 an January 2015 were included in the retrospective study. We evaluated clinical factors for overal survival (OS), no evidence of disease (NED) and non-ablation in relation to tumor sizes and numbers, type of approach and type of used probes.
RFA is an alternative approach to the treatment of unresectable CLM. In our study the open approach was associated with a lower risk of non-ablation.
Percutaneous RFA showed a lower risk of complications and shorter stay in the hospital.
