Local treatment of neuroendocrine liver metastases – How effective and safe is stereotactic microwave ablation?

#3801

Introduction: The less invasiveness of local ablation techniques such as stereotactic microwave ablation (SMWA) for the treatment of malignant hepatic lesions has made it an attractive alternative to conventional surgical resection.

Aim(s): The aim of this retrospective study was to assess the successful ablation rate of neuroendocrine tumor liver metastases (NETLM) 3 months after SMWA, the recurrence-free survival time, as well as the rate of peri- and early post interventional complications.

Materials and methods: Retrospective analysis including all patients treated with SMWA for NETLM in our institution between 03/2015 and 07/2022. SMWA was performed as per the decision of the interdisciplinary tumorboard. Patients were included independent of location of primary tumors, disease stage, prior treatments. Patients underwent follow-up imaging (FU) every 1-6 months.
