Safety and efficacy of transarterial interventional therapy for treatment of hepatocellular carcinoma with peritoneal metastases

Purpose: The aim of this study was to evaluate the safety and efficacy of transarterial interventional therapy for the treatment of hepatocellular carcinoma (HCC) patient with peritoneal metastases. Materials and Methods: A total of 7 HCC patients with peritoneal metastases were treated by interventional therapy. Combined treatment with transarterial chemoembolization for intrahepatic lesions and transarterial embolization for peritoneal metastases was performed through hepatic artery, gastroduodenal artery, and superior mesenteric artery. Results: Treatment resulted in an objective response of 85.7% Modified Response Evaluation Criteria in Solid Tumors. No severe adverse effects were observed. Conclusions: Transarterial interventional therapy can be performed safely and may improve the prognosis of HCC patients with peritoneal metastases.
