Background and Purpose: Liver metastases are common in neuroendocrine neoplasm (NEN). Cystic NEN liver metastases (cNENLM) are rare, and the efficacy of transarterial embolization (TAE) has not been reported. This study summarized and analyzed the efficacy and safety of TAE for cNENLM. Methods: From January 2016 to April 2022, 10 patients with cNENLM were enrolled in this study among 440 patients under TAE treatment at The First Affiliated Hospital, Sun Yat-sen University and Fudan University Shanghai Cancer center. The efficacy was evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. Objective response rate (ORR), disease control rate (DCR) and progression-free survival (PFS) were analyzed as well. The common terminology criteria for adverse events (CTCAE) v5.0 was applied to evaluate the adverse effects. Results: With 80.0% ORR and 100.0% DCR according to RECIST 1.1, 3 cases achieved PFS. Among them, the longest one was 25.0 months. Disease progression was not observed in the remaining patients. The common complications were fever, hepatalgia and transient liver dysfunction, which could be alleviated by symptomatic treatment. No severe complication occurred. Conclusion: cNENLM are infrequent. TAE had significant curative effect on cNENLM, and complications were manageable.
