70 hepatic resections were performed using 2450 MHz microwave scalpel. Primary diseased included hepatocellular carcinoma (46 cases), hemangioma (18), hepatobiliary tract stone (2), biliary cystadenoma (1), inflammatory pseudotumor of the live (1), metastatic liver cancer (2). Hemostasis was excellent despite liver cirrhosis in all cases. The average amount of blood loss and blood transfusion was 249 ml and 294 ml respectively. Blood transfusion was not necessary in 30 patients. All cases were free from postoperative bleeding from the liver stump and abdominal infection. No complications attributable to microwave coagulation were noted. We conclude that this new operative technique can be used safely and easily in the field of hepatic surgery.

We determined the plasma levels of urokinase-type plasminogen activator (u-PA) antigen and alpha-fetoprotein (AFP) in 44 patients with different stages of liver cirrhosis and in 29 patients with liver cirrhosis-based primary liver cancer at the time of first clinical detection of the malignant disease. Sensitivity values of u-PA and AFP in detecting primary liver cancer were 57 and 62%, respectively, and specificity values were 95 and 86%, respectively. A combination of both markers led to a significant increase of sensitivity to 89.7%. The specificity of the combination of both markers was 97.3%. In tumor patients with unilocular disease and tumor patients with multicentric disease and/or metastatic spread, similar sensitivity values could be obtained with both markers. Therefore, a combination of u-PA and AFP can increase the accuracy of detection of primary liver cancer, especially in chronic liver diseases known to be predisposing for primary liver cancer, e.g., liver cirrhosis of long duration.

Forty-one patients with cirrhosis and tense ascites were randomized to receive daily paracentesis of 5 liters associated with Dextran 70 as volume expander (6 g for each 1000 ml of ascites removed) (group I = 20 patients) or paracentesis with albumin (6 g for each 1000 ml of ascites) (group II = 21 patients). The basal clinical features, laboratory data, and plasma renin activity were similar in both groups. The volume of ascites removed was 12.9 +/- 4.4 and 10.9 +/- 3.7 liters in group I and II, respectively (n.s.). No significant changes were observed in liver and renal function tests, KPTT, platelet count, factor VIII, serum electrolytes or plasma renin activity 24 and 96 h after the last paracentesis in both groups, except for a decrease in bilirubin in group I and a transient increase of serum albumin in group II. Four patients developed complications in each group, mainly hyponatremia, while one patient in each group developed renal impairment. One patient from group I died with hepatic encephalopathy. Moreover, the probability of survival and readmission to the hospital because of tense ascites were similar in both groups of patients during the follow-up. The treatment cost with Dextran 70 was 15.50 dollars vs. 364.30 dollars with albumin for each patient treated. These results indicate that repeated large volume paracentesis associated with Dextran 70 is as effective and safe as paracentesis associated with albumin in cirrhotic patients with tense ascites. However, due to its reduced cost, paracentesis with Dextran 70 may be considered the treatment of choice in cirrhotic patients with tense ascites without liver cancer and renal failure.

Liver transplantation is the only effective treatment for hereditary tyrosinaemia type I (McKusick 276700). We have treated one acute and four subacute-chronic cases with 2-(2-nitro-4-trifluoromethylbenzoyl)-1,3-cyclohexanedione (NTBC), a potent inhibitor of 4-hydroxyphenylpyruvate dioxygenase (EC 1.13.11.27), to prevent the formation of maleylacetoacetate and fumarylacetoacetate and their saturated derivatives. The oral daily dose was 0.1-0.6 mg/kg. The excretion of succinylacetoacetate and succinylacetone decreased from 15-103 mmol/mol creatinine to the detection limit or slightly above (ie, to 20-150 mumol/mol creatinine). The concentration of succinylacetone in plasma decreased from 5.8-43 mumol/l to the detection limit (0.1 mumol/l) over 2-5 months of treatment. The almost complete inhibition of porphobilinogen synthase in erythrocytes was abolished and the excretion of 5-aminolevulinate decreased to within or slightly above the reference range. The concentration of alpha-fetoprotein decreased in four patients to 1.3-7.5% of initially high values over 6-8 months. Improved liver function was reflected by normal concentrations of prothrombin complex and in decreased activities of alkaline phosphatase and gamma-glutamyltransferase in serum. Computed tomography revealed regression of hepatic abnormalities in three patients. One patient developed rickets 6 months before treatment and had excreted high concentrations of markers of tubular dysfunction--after 3 weeks of treatment, this excretion had disappeared. No side-effects were encountered. Inhibition of 4-hydroxyphenylpyruvate dioxygenase may prevent the development of liver cirrhosis and abolish or diminish the risk of liver cancer. Normalisation of porphyrin synthesis will eliminate the risk of porphyric crises. This type of treatment may thus offer an alternative to liver transplantation in hereditary tyrosinaemia.

In Okinawa prefecture, prevalence of hepatitis B surface antigen (HBsAg) among blood donors is 3.5% and is twice as high as the average for the whole of Japan (1.5%), and is the highest in Japan (p less than 0.005). In contrast, mortality rates of both liver cirrhosis (LC) and primary liver cancer (PLC) in Okinawa are the lowest in Japan. Many epidemiological studies have shown that the positive rate of HBsAg correlates with mortality rate of PLC. To elucidate the cause of this epidemiological discrepancy, cross-sectional seroepidemiological studies and a prospective clinical study were conducted. In the cross-sectional studies, the following results were obtained; (1) Positive rate of HBsAg among patients with LC in Okinawa was 15.2% and lower than the average for the whole of Japan (23.4%). A similar comparison among patients with hepatocellular carcinoma showed 24.4% in Okinawa Vs. 31.4% in the whole of Japan. (2) The age-specific hepatitis B e antigen positive rate among 829 HBsAg positive health examinees tend to decrease with increase in age; 50% in less than 20 years old age group, 15.7% in third decade and 2-3% or less in 30 or more age group. Of the 829, 431 HBsAg positive subjects were referred our liver out-patient clinic. Then, of the 431, 27 (6.3%) were diagnosed or suspected as having chronic hepatitis and one (0.2%) was diagnosed as having cirrhosis. Of the 431, 381 (88.4%) were diagnosed as healthy HBsAg carrier, the great majority (94.0%) of whom had positive reaction of anti-HBe antibody and normal values of both GOT and GPT.(ABSTRACT TRUNCATED AT 250 WORDS)

We measured urinary levels of free L-fucose in healthy subjects, patients with benign diseases, and patients with cancer using an automated analyzer and a newly isolated L-fucose dehydrogenase, and evaluated the clinical usefulness of the results. The values obtained were corrected for urinary creatinine as micromoles per gram of creatinine. The cutoff value, set at the mean + 2SD for the healthy subjects, was 250 mumol/g.Cr. Patients with gallbladder cancer, bile-duct cancer, liver cancer, pancreatic cancer, or cirrhosis of the liver had significantly higher levels of L-fucose than the healthy subjects. The diagnostic sensitivity for these five diseases, taken together, was 68% (144/213). Specificity for the detection of cancer was calculated by use of false positives for patients with cholelithiasis, hepatitis, and pancreatitis: it was 73% (76/104). Diagnostic accuracy for these seven diseases taken together was therefore 69% (220/317). We compared the positive ratio of the L-fucose level with that of the tumor markers AFD and CA19-9. The positive ratio of an L-fucose value above the cutoff was higher than the positive ratio of either marker in bile-duct cancer, gallbladder cancer, liver cancer, and pancreatic cancer. The results suggested that the urinary levels of free L-fucose reflected the metabolism of sugar chains of glycoconjugates, and may be usefully clinically as a tumor marker.

During the period of 1958-1986, a series of 125 patients with pathologically proven hepatocellular carcinoma (HCC) surviving more than 5 years was collected in authors' institute. Thirty seven of them survived more than 10 years, the longest being 30 years. Of the entire series, 55.2% of patients was discovered by screening, 48.0% of patients was subclinical HCC, 80.0% of patients had solitary tumor, and 53.6% of patients had tumor size smaller than 5 cm. Pathological findings revealed that 90.2% of tumor was grade I and II (Edmondson grading) and 81.6% of patients associated with cirrhosis. The serum HBsAg was positive in 63% and anti-HBc in 80% of the patients who had checked the HBV markers. Of the 125 patients, 108 patients received resection, 67 patients were small HCC resection, 41 patients were non-small HCC resection, re-resection for subclinical recurrence or solitary lung metastasis was done in 26 patients with resection. Limited resection amounted to 54.6% of patients with resection. Of the 125 patients, 17 patients received palliative surgery other than resection, including hepatic artery ligation, cannulation, or their combination, etc. Eight out of the 17 patients received second stage resection due to marked shrinkage of tumor. It is concluded that early resection remained the major approach to get a long-term survivor, re-resection for subclinical recurrence is also of proved merit. Resection of huge tumor is still useful but less effective. Cyto-reduction and sequential resection is a new trend. Primary liver cancer (PLC) has long been recognized as incurable malignancy with extremely low 5-year survival rate. According to the cancer statistics in the United States, the relative 5-year survival rates for patients with PLC was 2% in 1960-1963, 3% in 1970-1973, 4% in 1974-1976, 3% in 1977-1980 and 5% in 1981-1986. Patients with PLC survived more than 5 years were rarely reported in the literature. In 1971, Curutchet collected worldwide data from 45 authors covering the period for 65 years (1905-1970), only 45 patients with PLC were found to be 5-year survivors. Thanks to the progress in tumor markers, particularly alpha fetoprotin (AFP) and new localization measurements, diagnosis and treatment are possible in subclinical stage. Based on combined strategies to the treatment of PLC including resection of small liver cancer, re-resection of subclinical recurrence after curative resection, multimodality treatment, and sequential resection after shrinkage of tumor, the 5-year survival of PLC has gradually increased.(ABSTRACT TRUNCATED AT 400 WORDS)

To clarify the potential role for HCV in the development of chronic liver disease in Yatsuka town with a high morbidity of liver disease, epidemiological studies were taken in 459 subjects of Yatsuka town compared with 219 subjects of Mihonoseki town with a low one. In Yatsuka town, the mortality rate of liver cirrhosis was three times higher than the overall rate in Simane prefecture, and the rate of liver cancer rapidly increased in recent years. Age and sex-matched epidemiological studies showed a significantly higher incidence of hepatic dysfunction compared with Mihonoseki town (11.5% vs 3.7%, P less than 0.01). The prevalence of HCV antibody was significantly higher in Yatsuka town than Mihonoseki town (16.6% vs 3.7%, P less than 0.001), although there were no differences in frequencies of HBs antigen and habitual alcohol drinker between the two districts. These data strongly suggest that the high prevalence of HCV may be associated with the high morbidity of chronic liver disease, especially hepatocellular carcinoma in Yatsuka town.

The aim of this study was to determine the risk of developing primary liver cancer in patients with a diagnosis of alcoholism, liver cirrhosis, or both. Three population-based, mutually exclusive cohorts were defined on the basis of hospital discharge diagnosis between 1965 and 1983. Complete follow-up through 1984--excluding the first year of follow-up--showed that among 8,517 patients with a diagnosis of alcoholism, 13 cancers occurred, vs. 4.2 expected (standardized incidence ratio (SIR) = 3.1; 95% confidence interval (CI) = 1.6 to 5.3); among 3,589 patients with liver cirrhosis, 59 cancers occurred, vs. 1.7 expected (SIR = 35.1; 95% CI = 26.7 to 45.3), and among 836 patients with both diagnoses, 11 cancers occurred, vs. 0.3 expected (SIR = 34.3; 95% CI = 17.1 to 61.3). Thus, alcoholism alone entailed a moderately increased risk and alcoholism with liver cirrhosis did not increase the high relative risk for liver cancer more than cirrhosis alone. We conclude that alcohol intake may be a liver carcinogen only by being causally involved in the development of cirrhosis; and further, that the risk of developing liver cancer following cirrhosis in this population is similar to or higher than that after chronic hepatitis-B-virus infection in other Western countries.

Benign liver tumors occurring in young women were rarely reported in the medical literature before the introduction of oral contraceptives in the early 1960s. Subsequently, there were numerous case reports from the U.S. and other countries of liver tumors in women who used combined oral contraceptives. These reports, coupled with data from two U.S. case-control studies, indicate that the risk of hepatocellular adenoma increases sharply with increasing duration of oral contraceptive use. Case reports suggest that there may be a similar effect on the risk of focal nodular hyperplasia, but this is not established because there have been no case-control studies of the lesion. The incidence of benign liver disease attributable to oral contraceptive use in the U.S. is small because of the very low incidence of the disease. There have also been numerous case reports of malignant liver tumors in young women who used oral contraceptives. Seven case-control studies have been conducted--two in Great Britain, two in the U.S., one in Italy, one in several developing countries (conducted by the World Health Organization (WHO)), and one in South Africa. Data from the first five studies, all conducted in low risk populations, indicated an association of hepatocellular carcinoma (largely in the absence of liver cirrhosis) with oral contraceptive use. Because of small numbers estimates were unstable, but the risk did not appear to be increased appreciably for durations of use less than about five years. For longer durations, the risk appeared increased by five- to tenfold or more. There was little evidence of hepatitis B infection in the cases, but systematic determinations were not carried out. An increased risk of cholangiocarcinoma was not established, but few of these lesions were studied. Because the incidence of primary liver cancer in Northern Europe and the U.S. is low, the incidence attributable to oral contraceptive use is also likely to be low. The WHO study was carried out in eight countries, most of which have a high incidence of liver cancer and a high prevalence of a predisposing factor, hepatitis B infection. Similarly, the South African study was carried out among black women, and virtually all of the cases had serological evidence of hepatitis B infection. Both studies indicated no association of short-term oral contraceptive use with risk of hepatocellular carcinoma, and the WHO study indicated a lack of association with cholangiocarcinoma.
