The most appropriate approach to treating hepatocellular carcinoma (HCC) in the caudate lobe has not yet been determined. A series of 197 patients who had undergone curative hepatic resection for HCC were analyzed. Fifteen patients had HCC in the caudate lobe: three in the Spiegel lobe (SP), three in the caudate process (CP), and nine in the paracaval portion (PC). Patients with HCCs in the SP and CP underwent partial hepatectomy. HCCs in the PC were approached in one of three ways: anterior approach and partial hepatectomy of the PC (Ant+PHx-PC), partial hepatectomy, or left lobectomy. Clinicopathologic variables, including the underlying liver disease, the mean tumor size, and the pathologic characteristics of HCC, did not differ between surgery of the caudate lobe and that of other segments. The overall survival was 88.9% at 3 years and 66.7% at 5 years after resection of HCC in the caudate lobe; the corresponding figures were 86.1% at 3 years and 68.6% at 5 years for the other segments. The recurrence-free survival rate was 51.9% at 3 years and 34.6% at 5 years for the caudate lobe, and it was 52.1% at 3 years and 32.8% at 5 years for the other segments. Clinicopathologic characteristics of HCCs originating in the caudate lobe were not different from those in the other segments. Limited resection of HCC in the caudate lobe confers a similar prognostic value as in other segments.
