A Case of Peritoneal Metastasis from Hepatocellular Carcinoma That Was Treated with Balloon-Occluded Transarterial Chemoembolization

抄録

Peritoneal metastasis is a relatively rare manifestation of metastasis from hepatocellular carcinoma. The prognosis of peritoneal metastasis is generally poor, because multiple metastases can occur. It has been reported that hepatocellular carcinoma can be treated with balloon-occluded transarterial chemoembolization. However, there have been no reports of the treatment of peritoneal metastasis from hepatocellular carcinoma with transarterial chemoembolization. A 65-year-old man had a history of partial hepatic resection of segment 8 for hepatocellular carcinoma. At that time, a percutaneous tumor biopsy was performed. Follow up computed tomography showed hepatocellular carcinoma in segment 4, and peritoneal metastasis. Therefore, the patient was admitted for treatment of the hepatocellular carcinoma and its peritoneal metastasis. The feeding arteries to the peritoneal metastasis were identified and treated with balloon-occluded transarterial chemoembolization. Two months after transarterial chemoembolization, contrast-enhanced computed tomography showed greater than 50% tumor necrosis.
