Abstract. When multiple hepatic tumors are present, it is sometimes difficult to distinguish between metastatic and multicentric hepatocellular carcinoma (HCC). To identify the important clinicopathologic features of multicentric HCC, we evaluated the clinical characteristics of patients with multicentric HCC and examined the usefulness of surgical treatment in those patients. A total of 99 patients with multiple HCCs were classified into one of the following two groups according to whether their tumors were multicentric or metastatic: Group MO consisted of 18 patients with tumors thought to have developed synchronously from multicentric origins. Group IM consisted of 64 patients with intrahepatic metastases. In this study 18% of the patients with multiple HCCs were thought to have presented with multicentric tumors. This study revealed that synchronous multicentric HCCs often affected multiple segments of the liver and responded relatively well to partial hepatectomy of individual tumor-affected areas. To appropriately treat potentially multicentric HCC, it is important to understand the histopathologic characteristics of multicentric HCC and diagnose during preoperative and intraoperative ultrasonography, so surgical treatment may be useful.
