The diagnostic value of plasma abnormal
prothrombin
(PIVKA-II) measurements in detecting relatively small hepatocellular carcinomas (
HCC
), less than 5 cm in diameter, was compared with that of serum alpha-fetoprotein (AFP) determinations. Among 18 patients with relatively small
hepatocellular carcinoma
(
HCC
), abnormal PIVKA-II values were found in only three (16.6%). Highly elevated serum AFP levels (greater than 200 ng/ml) relatively specific for
HCC
were seen also in three patients. However, nonspecific elevation of PIVKA-II in patients with liver cirrhosis not accompanied by
HCC
was much less than that of AFP. Although complementary, both tests appear to be of limited value in early detection of
HCC
, indicating that searches for other markers are necessary, to allow early detection of small
HCC
.

By means of staphylocoagulase, plasma des-gamma-carboxy
prothrombin
(DCP) was measured in 255 subjects. Of these, 59 were healthy controls, 100 had primary
hepatocellular carcinoma
(PHC), 33 had cirrhosis of the liver, 16 had hepatitis, 11 had metastatic carcinoma of the liver (MCL), and 36 subjects had previously been treated with anti-vitamin K drugs. The mean plasma DCP level in the healthy subjects was 3.02 VGH U/l. Of PHC patients 80% had DCP levels greater than 6 VGH U/l, which we regarded as probably abnormal. None of the patients with benign liver diseases (cirrhosis of liver or hepatitis) had DCP greater than 10 VGH U/l. Of the patients with MCL 54.54% had DCP greater than 6 VGH U/l. In our study DCP was found to be as sensitive a tumor marker as alpha-fetoprotein (AFP) in the diagnosis of PHC and was better in distinguishing PHC from benign liver disease. Of PHC patients 92% had at least one of the two tumor markers. Simultaneous determination of DCP and AFP should be applied in mass survey programs for detecting PHC, especially in countries with a high prevalence of hepatitis B virus infection.

With the aim of improving the biological diagnosis of
hepatocellular carcinoma
(
HCC
), alpha-fetoprotein (AFP), des-gamma-carboxyprothrombin (DCP) and factor V levels were assayed in 119 patients with
HCC
and 60 cirrhotic patients without
HCC
. Among the patients with
HCC
, increased levels of AFP (greater than 300 ng/ml) and of DCP (greater than 15 mU/ml) were observed in 36% and 69% of the cases, respectively. None of the 60 patients without
HCC
had increased AFP, and one had abnormal DCP; in this patient, DCP level returned to normal value after vitamin K1 injection. No significant correlation was found between increased AFP and DCP, thus indicating that the two tests complement each other for the diagnosis. A factor V level higher than expected from the reduced
prothrombin
time test of the patient was detected in 50% of patients with
HCC
and only 7% of those without
HCC
. No correlation was found between increased factor V and abnormal AFP or DCP. The thrombin time, fibrinogen activity to antigen ratio, and polymerization index failed to differentiate between cirrhosis and
HCC
. We conclude that AFP, DCP and factor V may give complementary informations in the diagnosis of
HCC
, one of these markers at least being positive in 88% of the patients.

Plasma abnormal
prothrombin
(protein induced by vitamin K absence or antagonist-II: PIVKA-II) was evaluated as a serological marker for
hepatocellular carcinoma
(
HCC
). Its plasma levels were measured by enzyme immunoassay using an anti-PIVKA-II monoclonal antibody in 1010 patients with various diseases. Of 192 patients with
HCC
, 116 (60%) had abnormal PIVKA-II levels greater than 0.1 AU/ml. Elevation of PIVAK-II levels was observed rarely in chronic hepatitis, liver cirrhosis and other malignant tumors. Plasma PIVKA-II levels in
HCC
increased with tumor size. Normal levels were observed in patients with tumors measuring 2 cm or less in diameter. As a result, diagnostic application of plasma PIVKA-II levels to small liver tumors is limited. The sensitivity of PIVKA-II in the diagnosis and monitoring of
HCC
was increased by serial and simultaneous determinations of AFP, because high PIVKA-II levels were observed more often in low AFP-producing
HCC
patients. In some patients with
HCC
, plasma PIVKA-II levels decreased after surgical resection of the tumor or chemoembolization with cisplatin suspended in Lipiodol (LPS), but later rose again with recurrence of the disease. Elevated plasma PIVKA-II levels were not related to low vitamin K concentration in the serum. In fact, in many patients vitamin K administration resulted in only a moderate reduction of PIVKA-II levels. From these results, plasma PIVKA-II assay by the EIA method using a monoclonal antibody is a useful tool for the diagnosis and monitoring of
HCC
, particularly in
HCC
patients with low AFP levels.

A method to prepare cisplatin suspended in an oily lymphographic agent, Lipiodol (LPS), has been established to deliver cisplatin to
hepatocellular carcinoma
(
HCC
) by the hepatic artery. Seventy-one patients, one Stage I, 16 Stage II, 16 Stage III, and 38 Stage IV, were treated with LPS therapy. A partial response was obtained in 33 cases (46.5%), a minor response in 20 cases (28.2%), and no change in 18 cases (25.3%). In 34 patients whose serum alpha-fetoprotein (AFP) levels were greater than 400 ng/ml, the serum AFP levels decreased in 31 patients (91.2%). The AFP decreased by more than 50% in 25 cases (73.5%) and more than 75% in 19 cases (55.9%). The plasma des-gamma-carboxy
prothrombin
(DCP) levels decreased in all of the 26 DCP-positive patients. The survival rate was 77% at 6 months and the 1-year survival rate was estimated to be 55%. The patients treated with LPS therapy survived longer compared with patients given Lipiodol containing neocarzinostatin by the hepatic artery. Complications such as acute gastroduodenal mucosal lesions (24%), cholecystitis (2.8%), pancreatitis (7%), delayed jaundice (7%), and hepatic encephalopathy (4.2%) were observed after therapy. The peak plasma platinum (Pt) concentrations determined as ultrafilterable Pt occurred 5 to 20 minutes, and 5 to 60 minutes as total Pt after the end of LPS injection. The Pt concentrations in the tumor tissues were 42 times higher in four operated cases and 7.1 times higher in six autopsy cases than those in the nontumorous tissue. These results suggest that LPS selectively accumulates in the
HCC
, is long-lasting and gradually releases the drug. In addition it is effective as a new anti-cancer therapy for
hepatocellular carcinoma
.

Des-gamma-carboxy
prothrombin
(DCP), a precursor of
prothrombin
, has been reported recently to be as good a marker, or even better, of
hepatocellular carcinoma
than alpha-fetoprotein (alpha-FP). The sensitivity, specificity and predictive values of the two markers have been compared in 98 southern African Blacks with
hepatocellular carcinoma
and in 120 Black controls with various diseases which might be mistaken clinically for this tumour: 32 with hepatic metastases, 33 with amoebic hepatic abscesses, and 55 with chronic hepatic parenchymal disease. DCP levels were measured using a chromogenic assay with Dispholidus typus venom and staphylocoagulase. The agreement between the two methods was excellent (r = 0.995). alpha-FP concentrations were measured by radioimmunoassay. DCP levels were raised in 66 of 98 patients (67.3%) and alpha-FP levels in 82 of 98 patients (83.7%) with
hepatocellular carcinoma
(P = 0.006). The specificity of DCP was also less than that of alpha-FP, although the difference just failed to reach statistical significance (P = 0.085). The predictive values of both a positive and a negative test for DCP were significantly less than those for alpha-FP (P = 0.047 and 0.048, respectively). When, in an attempt to eliminate false positive results, the diagnostic cut-off level for DCP was increased from 1.5 to 5.0 mu/ml and that of alpha-FP from 20 to 400 ng/ml, the differences between the two markers remained the same. If the two tests were used together, the number of false negative alpha-FP results was reduced from 16.3% to 7.1% and the number of equivocal alpha-FP results was reduced from 11.2% to 5.1%.(ABSTRACT TRUNCATED AT 250 WORDS)

Bleeding complications during liver transplantation have been attributed to accelerated fibrinolysis. In order to determine its cause, 11 adults (mean age: 38.9 +/- 13.2 yr) undergoing liver transplantation were studied. There were three groups of patients: cirrhosis (n = 4), fulminating hepatitis (n = 4) and one group including a primary biliary cirrhosis, a hepatic metastasis and a
hepatoma
. The following factors were studied in the immediate preoperative period, at different surgical times throughout the procedure and 2-3 h after the end of the abdominal sutures: platelet count,
prothrombin
concentration, fibrinogen, activated kephalin time, factors II, V, VII + X and VIIIc, antithrombin III, protein C, D-dimers, fibrinogen and fibrin degradation products (PDF), plasma plasminogen, tissue plasminogen activator (tPA) and the fast tPA inhibitor (PAi). Preoperatively, only the two patients with hepatic cancer had a normal haemostatic profile. Throughout the procedure, all patients had only moderate changes in platelets, coagulation factors and their inhibitors, and plasminogen, because platelet concentrates and fresh frozen plasma were transfused. Levels of tPA rose, becoming very high during the anhepatic period and just after graft reperfusion. An abrupt fall occurred at the end of surgery. There were important individual differences in tPA activity. PAi activity was low during the preanhepatic and anhepatic stages, rising rapidly after revascularization.(ABSTRACT TRUNCATED AT 250 WORDS)

The concentration of abnormal
prothrombin
, or the protein induced by vitamin K absence or antagonist II (PIVKA-II) in 102 patients with hepatic disorders was measured by an enzyme immunoassay method. The concentration of PIVKA-II in the plasma was elevated in 11 out of 18 patients with
hepatocellular carcinoma
and also in a patient with hepatoblastoma. There was no correlation between serum alpha-fetoprotein and plasma PIVKA-II levels. The PIVKA-II level was normal in 11 patients who had metastatic carcinoma or cholangiocellular carcinoma. Moreover, benign diseases of the liver did not cause an elevation in PIVKA-II. PIVKA-II might be an useful marker of
hepatocellular carcinoma
because, like alpha-fetoprotein, its level changes in close relation to the effects of treatment.

To evaluate the clinical value of splenectomy for hepatic resection, a total of 20 patients with
hepatocellular carcinoma
and hypersplenism were examined focusing on a change of total serum bilirubin values after surgery. Both hepatectomy and splenectomy were simultaneously performed in 12 patients, and in 8 patients as a staged operation. Postoperatively, a significant depression of bilirubin values was observed in a group with the preoperative values between 1.0mg/dl and 2.0mg/ml. Three factors (bilirubin, albumin and
prothrombin
time) in clinical stage were improved just after splenectomy with a statistical significance (p less than 0.05) in a group received staged operation. In 7 out of 8 patients, clinical stages were getting better as one or two stages prior to the hepatectomies. Therefore, we recommend the addition of splenectomy to hepatectomy in the patients whose hyperbilirubinemia are assumed to be correlated with coexisting hypersplenism.

Antipyrine (AP) clearance was determined in 23 cases with liver cirrhosis (LC), 12 with chronic active hepatitis (CAH), 12 with
hepatocellular carcinoma
(mcHCC), 20 with non-hepatic diseases and 70 healthy controls. ICG Clearance was performed simultaneously in 9 cases of them. The results showed that AP clearance was significantly decreased in patients with LC and moderately decreased in CAH and
HCC
, its diagnostic sensitivity in LC was significantly higher than that of GPT. The significant positive correlation between the AP and ICG clearance was noted and AP clearance also well correlated with serum albumin level and
prothrombin
time. It is suggested that AP clearance may be used as a quantitative test to determine the reserve capacity of liver and as a substitutive test for ICG clearance.
