We read with interest the article by Auernhammer and Göke1 on therapeutic strategies for liver metastasis in neuroendocrine carcinomas. Local tumour progress following radiofrequency ablation (RFA) occurred in only 6% of neuroendocrine carcinomas, but no data on overall survival and prognostic factors following RFA were available. As another thermal ablative technique for liver cancer, microwave ablation (MWA), which uses electromagnetic energy to rapidly rotate adjacent polar water molecules to achieve primarily active heating, shows the following advantages: higher intratumorous temperatures, larger ablation …
