Cost-effectiveness of percutaneous radiofrequency ablation for malignant hepatic neoplasms.

摘要

PURPOSE: Percutaneous radiofrequency (RF) ablation is a promising technique for the treatment of hepatic malignancies. However, its cost-effectiveness has not been established. The purpose of this study is to determine the cost-effectiveness of RF ablation compared to palliative care in the treatment of hepatocellular cancer and colorectal liver metastases. This study also seeks to evaluate the effects of transition from traditional to newly implemented prospective outpatient reimbursement mechanisms on RF ablation cost-effectiveness. MATERIALS AND METHODS: The marginal direct costs of a percutaneous RF ablation treatment strategy were compared to palliative care over a range of survival benefits with use of a cost-effectiveness model built from the perspective of the payer. Variables used in the model, including complication rates and procedure efficacy, were obtained from the literature and the authors' experience with 46 consecutive patients. RESULTS: The cost-effectiveness of a standardized percutaneous RF ablation treatment strategy compared to palliative care was
