The aim of this retrospective study was to assess the prevalence of hepatitis C virus antibodies and their follow-up in a series of 64 orthotopic liver transplantation patients. Indications for transplantation were cirrhosis in 28 cases, primary biliary cirrhosis in 6 cases, liver cancer in 11 cases, fulminant hepatitis in 2 cases, and alveolar echinococcosis in 17 cases. The prevalence of serum antibodies to hepatitis C virus was assessed by an ELISA test (Ortho-Diagnostic-Systems). Sera were tested before liver transplantation and every two months after. Twenty-nine patients seronegative before transplantation remained negative. Four patients seropositive before liver transplantation remained seropositive. Twenty-eight patients seropositive before transplantation, became seronegative after, and 3 patients seronegative before transplantation became seropositive after. The prevalence of seroconversion was 9.3 percent. The prevalence of seropositive patients after transplantation was 11 percent. The high number of seropositive patients before transplantation (50 percent) could be explained by false positive results. Seropositivity before transplantation appeared to be related to hypergammaglobulinemia (p less than 0.001). This hypothesis was confirmed a posteriori by a concomitant disappearance of both seropositivity and hypergammaglobulinemia after transplantation in 62 percent of patients.

The purpose of this study was to investigate the relationship between life style factors and adult diseases among three ethnic groups, Chinese living in Japan, Koreans living in Japan and Japanese. The mortalities of major cancers and other adult diseases of Chinese and Koreans in Japan were compared with those of Japanese by calculating Standardized Mortality Ratios (SMR) of the two groups using death rates in the Japanese population as the standard. Life style data on smoking, drinking and dietary habits of the three groups were collected by self-administered questionnaire surveys, and age-adjusted proportions were calculated with the truncated world population as the standard. The results are summarized as follows: 1. The mortality rates for liver cancer, lung cancer, diabetes mellitus, heart disease, hypertensive disease, cerebrovascular disease and liver cirrhosis for Koreans of both sexes in Japan were significantly higher than those for Japanese, but the mortality rates of stomach cancer, pancreatic cancer and breast cancer for Korean females were lower than those for Japanese females. 2. The mortality rates for heart disease, diabetes mellitus, hypertensive disease, liver cirrhosis, rectum cancer, liver cancer, lung cancer (females), breast cancer (females) and cerebrovascular disease (females) for Chinese in Japan were higher than those for Japanese, but the rates for stomach cancer, pancreatic cancer (both sexes), uterus cancer (females) and cerebrovascular disease (males) were lower than those for Japanese. 3.(ABSTRACT TRUNCATED AT 250 WORDS)

Antibodies to the pre-S1-encoded sequence of hepatitis B virus (HBV) envelope were detected by ELISA using a synthetic peptide analogue of preS1 proteins, in different groups of HBV-infected subjects and also in hepatitis B vaccine recipients. Such antibodies were specifically found in only 1% of HBsAg chronic carriers including patients with cirrhosis and primary liver cancer. Anti-preS1 were detected in patients with acute hepatitis; in 13% of the HBsAg+ sera obtained before recovery and in 37% of the sera obtained after recovery. Anti-preS1 antibodies were detected in recipients of a plasma-derived vaccine, but not in those receiving a recombinant vaccine. The results indicate that anti-preS1 is an earlier serum marker of HBV clearance than anti-preS2 and anti-S antibodies.

The etiologic relationship of a parasitic liver disease to primary liver cancer has long been debated, and reported is a case that has been encountered of a primary liver cancer coincident with Schistosomiasis japonica. A fifty-nine year-old-man was diagnosed as having a primary liver cancer complicated with liver cirrhosis. A posterior segmentectomy was performed and a microscopic examination revealed a primary liver cancer with multiple ovae of Schistosoma japonicum in the fibrous stroma of the portal spaces. Discussed is the etiologic relationship of Schistosomiasis japonica to the primary liver cancer.

In previous studies we have shown that male rats carrying genes controlling growth and reproduction (grc) linked to the major histocompatibility complex (MHC) to be more susceptible to N-2-acetylaminofluorene than rats without grc genes. In the present studies we show that by manipulation of the diet of grc rats, hepatocarcinogenesis induced by another carcinogen can be altered. Male rats with the grc gene (R16) and wild type (ACP) were initiated with diethylnitrosamine (DEN) (200 mg/kg body weight). Some were fed laboratory chow (LC) for 9 months; others were fed a choline-supplemented (CS) or a choline-deficient (CD) diet. The rats were killed at various time periods and the liver sections were stained with H&E and for gamma-glutamyltranspeptidase (GGT). After 9 months on LC, the livers of R16 showed greater size and number of GGT-positive foci, bile duct proliferation, cellular atypia, cirrhosis, and nodular hyperplasia than the ACP. While the first hepatocellular carcinoma in R16 fed either a CS or LC was seen at 9-10 months, one R16 rat fed a CD diet had liver cancer at 4 months. On a CS diet the R16 showed greater GGT-positive foci at 2 months than the ACP. On a CD diet the R16 showed even greater size and number of GGT-positive foci. At 12 months, 15 of 22 (68%) of the R16 rats on a CD diet had liver cancer and seven of 24 (29%) of the R16 on a CS diet. Of the ACP, none of 15 (0%) on CS and one of 18 (6%) on CD diet had liver tumors. The results show that the grc genes confer high susceptibility to liver cancer, which is enhanced by a CD diet, suggesting synergism between genetics and diet.

Two major aetiological factors have been definitively incriminated in the pathogenesis of HCC: these are chronic hepatitis and hepatic cirrhosis. Chronic infection with hepatotropic viruses may account for the majority of cases of hepatocellular carcinoma in high incidence areas, and a varying prevalence of human hepatitis B and hepatitis C virus infection appears to determine the differing geographical prevalence of hepatocellular carcinoma in high and low incidence areas of the world. Patients with advanced hepatocellular carcinoma have a grave prognosis. However, at-risk groups have been characterized, and recent advances in hepatic imaging and tumour marker testing have made screening for asymptomatic primary liver cancer feasible. It it not clear, however, whether screening for small hepatocellular carcinoma improves the prognosis. Lipiodol has been shown to serve as a useful vehicle for diagnosis of small, centimetre sized nodules of tumour, and for delivery of cancer chemotherapeutic or radioactive agents to HCC. The combination of early diagnosis, and coupled medical and surgical treatments including targeted lipiodol or monoclonal antibody conjugates and hepatic resection or transplantation may lead to an improved outlook for viral-associated hepatocellular carcinoma.

Arterial ketone body ratio (AKBR) were examined in 114 cases of hepato-biliary tract diseases. AKBR of the normal control was 1.47 +/- 0.38, while it remained less than 0.7 in liver cirrhosis, hepatocellular carcinoma (HCC), alcoholic liver diseases and malignant biliary tract obstruction. AKBR correlated well with serum albumin and cholinesterase. Thirty five cases of HCC were treated with transcatheter arterial embolization (TAE), 20 cases with gelatin sponge and 15 cases without gelatin sponge. In cases with gelatin sponge AKBR decreased significantly immediately after TAE and recovered gradually during 24 hours. Without gelatin sponge AKBR decreased slightly and remained unchanged until 24 hours later. Concerning the prognosis after TAE, AKBR recovered well in cases with good prognosis, while in poor prognosis AKBR progressively decreased to below 0.3. In experimental TAE with gelatin sponge using rabbit VX2-induced liver tumor, AKBR decreased significantly. In fatal rabbit group after TAE, AKBR decreased progressively. Plasma endotoxin was also measured in TAE with experimental rabbit, AKBR and endotoxin showed reverse correlation. From these results it was suggested that the measurement of AKBR is very useful for the evaluation of efficacy and prognosis of TAE in primary liver cancer.

Fifteen patients with liver cirrhosis and 15 with primary liver cancer were studied. The results of cellular immunity in these two groups and a third control group of 15 healthy subjects were compared. A significant decrease in OKT3 and OKT4 lymphocytes and response to different mytogenic stimuli were found, particularly in the hepatocarcinoma group. No significant differences were observed in OKT8, OKM1 or chemotaxis.

Periodic checkup by ultrasonography was conducted on patients with chronic liver diseases for early detection of hepatocellular carcinoma. In 19 months, a total of 2004 examinations were performed on a total of 660 cases (179 cases with liver cirrhosis in the compensatory stage, younger than 70 years; 481 cases with chronic hepatitis, aged 40 to 70 years for men and 50 to 70 years for women). Of the 660 cases, 22 HCC cases (3.3%) were detected and finally diagnosed by angiography and/or histologic examination. Four of those cases (18%) had a single nodule smaller than 1 cm in diameter, and 11 cases (50%) had a single nodule smaller than 2 cm. Surgical resection was performed on 12 cases (55%). In comparison with the control group (83 HCC cases not receiving any periodic checkup), the frequency of small liver cancer and the surgical resection rate in the study group were significantly higher. This examination system by periodic ultrasonography checkup of patients with chronic hepatic diseases was effective for early detection and permitted aggressive therapy of hepatocellular carcinoma.

Although primary liver carcinoma is one of the most common forms of malignancy in most parts of Africa and the Far East, recent reports indicate that the incidence of primary liver cancer has been increasing in Western countries. Our retrospective study is in agreement with this suggestion. From 28,311 autopsies performed at the Department of Pathology in Hradec Kralove from 1951 to 1978, 91 primary liver carcinomas were found. The increase was apparent in the period 1971 to 1978: 0.53% compared to 0.22% in the period 1951 to 1970. Of the 91 cases, 68 were in association with cirrhosis. In 6 of 17 liver samples, aflatoxin B1 was proved. Some authors suggest that the increase of liver cancer is related to the increase of cirrhosis. Other authors note a striking association of tumors with HBAg. The increase of cirrhosis has not been confirmed in our study. We assume that the carcinogenic mechanism is more complex and that the determinating factor might be an interaction of HB infection and some of the environmental carcinogenic factors, e.g., aflatoxin.
