A total of 850 patients with hepatocellular carcinoma seen during the last 8 years were analyzed retrospectively for survival in relation to treatment and disease stage. A new staging scheme based on tumor size, ascites, jaundice and serum albumin was used. Clearly, the prognosis depended on disease stage. The median survival of 229 patients who received no specific treatment was 1.6 months, 0.7 month for Stage III patients, 2.0 months for Stage II, and 8.3 months for Stage I. The median survival of Stage I patients who had hepatic resection (n = 115) was 25.6 months and Stage II patients with resection (n = 42) was 12.2 months. In patients who had a small cancer (less than or equal to 25% of liver area in size) the median survival was 29.0 months. Survival of the surgically treated patients, which represented a highly selected group, was better than that of medically treated patients of a comparable stage. Median survival of Stage I medically treated patients (n = 124) was 9.4 months, for Stage II (n = 290) 3.5 months, and for Stage III (n = 50) 1.6 months. Medical treatment prolonged survival in Stage II and III patients, but not in Stage I. Transcatheter arterial embolization gave a better survival compared with chemotherapy, whether intra-arterial bolus administration of mitomycin C, systemic mitomycin C, or oral/rectal tegafur, in Stage II. Among various chemotherapeutic modalities, intra-arterial bolus injection was superior to systemic chemotherapy in survival in Stage II. In Stage III, chemotherapy improved survival as compared with no specific treatment. The major causes of death were hepatic failure and gastrointestinal bleeding, probably due to the coexistent advanced cirrhosis. These results in survival are much improved over the past reports, and the differences are probably a result of earlier diagnosis and frequent hepatic resections.

The clinical features of 57 autopsied cases of intrahepatic bile duct carcinoma including 28 cases of the peripheral type (cholangiocarcinoma in the narrow sense) and 29 cases of the hilar type are described in comparison with those of hepatocellular carcinoma, with a review of the literature on the clinicopathological aspects of intrahepatic bile duct carcinoma. As compared with hepatocellular carcinoma, the average age of the patients was older; the male predominance was not obvious, chronic parenchymal liver disease was infrequent in the past history, association of primary cirrhosis was seldom, cholestatic features were frequently the early signs and more pronounced during the course, the liver was enlarged to a lesser extent, ascites was less common, signs of portal hypertension were absent or minimal, a n d extrahepatic metastases were less frequent. In many respects, the hilar type resembled extrahepatic bile duct carcinoma, and the peripheral type was somewhat between it and hepatocellular carcinoma. Although the overall survival was not much different from that for hepatocellular carcinoma, early diagnosis is emphasized; this would make surgical management possible. Differential diagnosis from hepatocellular carcinoma may be possible in the majority with direct cholangiography , liver scan, celiac angiography, determination of a-fetoprotein and hepatitis B antigen, and blood chemistry such as SCOT, SLDH, serum bilirubin and alkaline phosphatase. Illustrative cases are given including one patient with a hilar carcinoma who survived for more than 2 years after transhepatic biliary drainage.
