(1) Passive hemagglutination and radioimmunoassay are suitable methods for the detection of AFP in the low concentration range. (2) In 3.72% of the cases a clinically unknown carcinoma was found in an unselected group of patients with liver cirrhosis. (3) 21.9% of the patients showed AFP elevations up to 2000 ng/ml. In 10.6% of this group, increasing titers demonstrated a primary liver cell carcinoma. In 89.4% a transitory rise of AFP was not associated with tumor growth. Levels return to normal values within three months in 90% of the cases. (4) Transitory AFP elevations are not correlated to clinical conditions (praecoma, coma, delirium, bleeding, ascites, shunt) or to biochemical parameters (GOT, GPT, bilirubin, prothrombin complex time, gamma-globulin). (5) A temporary rise in AFP is more frequently observed in groups with high hepatoma incidence than in groups with low hepatoma incidence. (6) Therefore, it may be suggested that a transitory rise of AFP could reflect a "primary reaction" of carcinogenesis. (7) Primary liver cell carcinoma is found to be more frequent in posthepatitic than in postalcoholic, cryptogenic, and other cirrhosis and to be more frequent in australia-antigen positive than in australia-antigen negative cases. (8) Routine serological tumor antigen screening of patients with a precancerous disease is useful.

Sixteen necropsies and 4 cases of hepatic resection in which the liver had a solitary hepatocellular carcinoma smaller than 4.5 cm, or a few tumor nodules smaller than 3.5 cm, have been analyzed. Clinically, these patients presented with signs and symptoms compatible with cirrhosis and, of the 16 autopsy cases only 2 had been diagnosed correctly. In all but 4 cases, the noncancerous parenchyma showed advanced cirrhosis of the mixed type, with irregularly sized multilobular nodules and thin strands of stroma, different from typical alcoholic cirrhosis. The primary lesion was grossly encapsulated in the majority, suggesting a slow, expanding growth. Histologically, most primaries were relatively well differentiated. Serum alpha-fetoprotein was generally low, and it served as the major diagnostic clue in only 5 cases. In patients with mildly abnormal alpha-fetoprotein levels, continuous monitoring seems important in order to detect a steady rise, the first warning for tumor growth.

Serum alpha 1 antitrypsin, alpha 1 acid glycoprotein and beta 2 glycoprotein I concentrations were determined in 36 patients with malignant hepatocellularcarcinoma, 30 with cirrhosis and 35 with hepatitis by quantitative immunoelectrophoresis. Serum alpha 1 antitrypsin and alpha 1 acid glycoprotein levels were significantly higher in patients with hepatocellularcarcinoma than in those with cirrhosis (p less than 0.001) or hepatitis (p less than 0.001). Elevated levels of alpha 1 antitrypsin were found in 88.9% of patients with hepatoma compared to 23.3% of patients with cirrhosis and 28.6% of patients with hepatitis. Raised levels of alpha 1 acid glycoprotein were also found in 80.6% of patients with hepatoma compared to 20% of patients with cirrhosis and in only 5.7% of patients with hepatitis. beta 2 glycoprotein I levels were similar in the three conditions and therefore not useful for differential diagnosis. In monitoring the progress of tumor growth alpha 1 antitrypsin and alpha 1 acid glycoprotein levels were found to increase during the growth phase. Measurements of these two glycoproteins are suggested for differential diagnosis of these liver diseases, as tumor markers for the detection of hepatocarcinoma, and for the monitoring of the progress during treatment.

Circulating immune complexes (CIC), complement and alpha-fetoprotein (AFP) were detected in 93 hepatitis B surface antigen (HBsAg)-positive patients with hepatocellular carcinoma (HCC), 16 patients with liver cirrhosis (LC) and 54 healthy controls. The CIC and complements were significantly higher in HCC patients than in LC patients. The complement and polyethylene glycol(PEG)-CIC in HCC patients with LC were higher than those in LC only (P less than 0.0001). The complement levels in LC patients were significantly lower than in controls. There was no difference in C3 and C4 between HCC patients and controls, while the C3 proactivator was higher in HCC patients (P less than 0.02). The C1q-CIC was higher in HCC and LC patients when compared to controls (P less than 0.0001). In patients with HCC, there was no difference in the CIC and complement levels between patients with cirrhosis and those without. There were inverse correlations between C1q-CIC and C3 (P less than 0.05), C1q-CIC and C4 (P less than 0.04). The mean level of 3% PEG-CIC and C1q-CIC increased significantly as AFP elevated, but decreased as AFP was higher than 1599 ng/ml (P less than 0.05). These results imply that CIC increase with tumor growth but further tumor burden may result in a fall in CIC, there was a shifting of CIC from complement-fixing to non-complement-fixing as AFP increased gradually.

The role played by carotenoids, retinol and tocopherol in quencing oxidative cellular damage and combatting tumor growth is well documented, but little is known about their activity in human liver cirrhosis (LC), where oxidative damage and tumoral complications are common-place. We investigated 59 patients with LC of different etiology on admission to hospital and compared them with 32 healthy controls, matched for age and sex. Nutritional (cutaneous skinfolds, creatinine-height index) and serum parameters were determined; of these, alpha- and beta-carotene, cryptoxanthin, lycopene, retinol and alpha-tocopherol were detected by an high-performance liquid chromatographic (HPLC) technique, devised in our laboratory, which afforded an accurate and simultaneous resolution of all six compounds. The results point to a significant reduction in almost all the vitamin factors in LC, as well as in total serum lipids. In consequence, the ratio tocopherol/total serum lipids remains almost unchanged: 2.45 +/- 0.08 (m +/- se) in controls and 2.34 +/- 0.16 in patients. The effects of age, sex, nutritional habits, alcohol, malnutrition and the severity of the disease were also evaluated in relation to the vitamin-factor levels. It is suggested that the reduced levels observed in LC patients are due to a number of factors including portal hypertension and lymphatic circulation impairment, and it is concluded that thorough screening and improved diet are beneficial in the follow-up of LC.

The appearance of Hanganutziu and Deicher (HD) antibody in the sera of patients suffering from various diseases, including malignancies of some organs and liver disorders, was investigated by enzyme-linked immunosorbent assay using N-glycolylneuraminyl-lactosylceramide (HD3) and 4-O-acetyl-HD3 as the antigenic molecules. More than 25% of sera from patients suffering from malignancies, cholelithiasis and liver cirrhosis had HD antibody, whereas none of 41 sera from healthy persons had HD antibody. The percentage of HD antibody-positive patients was similar in stages I, II and III of gastric cancer and recurrence cases. Antibody titers of the positive patients in each stage were also not different from those in each other stage. These results indicated that HD antigenic expression on cancerous tissue is not dependent on the cancerous malignancy. The HD antibody level was elevated after surgical removal of cancerous tissues in 5 of 6 patients examined, indicating that tumor growth absorbed the serum antibody. Serum antibody against 4-O-acetyl-HD3 was detected independently of HD3 antibody in some cases; however, in most cases, correlation between the two antibody titers was observed.

The spontaneous rupture of hepatocellular carcinoma (HCC) constitutes usually critical and life threatening condition because of hypovolemic shock due to massive hemorrhage, underlying liver cirrhosis and extensive tumor growth. Recently, transcatheter arterial embolization (TAE) has been used for controlling arterial bleeding of spontaneous rupture of HCC. We report a long surviving case (1 year 9 months) with stage IV ruptured HCC treated by emergency TAE.

Prognostically relevant factors and treatment were analysed in 103 patients suffering from primary epithelial liver tumors (88 HCC, 15 CCC). Ninety of them underwent operations: 14 liver transplantations, 32 resections, 44 explorative laparotomies. The resection rate was 38%, the 30-day mortality in transplantation 14%, in resection 22%. The 5-year survival after resection was about 25%. Liver transplantation resulted in 50% 1-year and 40% 2-year survival. Long-term prognosis was positively influenced by cirrhosis and formation of a tumor capsule. Indications for operative management depend only on extension of tumor growth and concomiting liver cirrhosis as biology of epithelial liver tumors is poorly understood.

The present study deals with the natural history of 37 asymptomatic patients with cirrhosis and hepatocellular carcinoma, 25 with 2-9-cm tumors who were not surgically treated (first group) and 12 with tumors smaller than 4 cm who underwent resection (second group). All patients were in Child's A class. Two-year survival (according to life-table analysis by the Kaplan-Meier method) was 50% in the first group and 39% in the second group. This difference was not significant. In the first group no relation was found between survival and initial tumor size or alpha-fetoprotein levels. Ultrasound examinations at 3-mo intervals revealed the following patterns of tumor growth: (a) no significant growth during the follow-up (9 patients); (b) significant growth (tumor size at least doubling) only in the final stage of the disease (11 patients); (c) initial significant growth followed by a period of no increase in size (5 patients). These findings show that in our geographical area (a) 2-yr survival of untreated asymptomatic patients with hepatocellular carcinoma associated with cirrhosis does not differ from that of similar patients undergoing resection and (b) the tumor can exhibit long periods of no growth alternating with periods of exponential growth.

The activity of serum type IV collagen-degrading enzyme was measured in 18 patients with hepatocellular carcinoma (HCC). The enzyme activity was significantly higher, in HCC patients with a tumor thrombus in the portal vein than in healthy controls, liver cirrhosis patients and HCC patients without a tumor thrombus. Moreover, the activity in HCC patients with lung metastasis tended to be higher than that in HCC patients without lung metastasis. The activity of serum type IV collagen-degrading enzyme did not correlate with tumor size, serum alpha-fetoprotein level, or macroscopic classification of tumor growth. These results suggest that the activity of serum type IV collagen-degrading enzyme represents the metastatic potential or the ongoing metastatic activity of HCC. The enzyme is a useful serum marker of metastasis from HCC.
