The clinical features of 77 patients with primary liver cell carcinoma seen over a nine-year period were examined. Eighty per cent of the patients had underlying cirrhosis, of alcoholic origin in most cases. In nine of the patients hepatitis B surface antigen was found in the serum; all nine patients were born in areas where hepatitis B virus infection is endemic. Abdominal pain and ascites were the most common presenting symptoms; they are due mainly to the locally invasive nature of the tumour. A confirmatory laboratory finding in the diagnosis is the observation of raised alkaline phosphatase levels and the presence of alpha-fetoprotein in the serum. The diagnosis should be established without performing a laparotomy and should seriously be considered in a previously stable patient with cirrhosis who deteriorates clinically without obvious cause.

A 57-year-old man with hepatocellular carcinoma with left thigh-bone metastasis is reported. He was admitted to the hospital with left leg pain. A diagnosis of bone metastasis of unknown origin was based on X-ray films. Physical examination revealed hepatomegaly. Liver function tests showed a slight increase of alkaline phosphatase, GOT and GPT. In serological tests, the levels of alpha-fetoprotein and carcinoembryonic antigen were high. HBs antigen was negative. From the above data, hepatocellular carcinoma was diagnosed.

The patient was a 60-year-old Japanese male. He complained of epigastralgia and right chest pain of 4 month's duration, and general malaise, nausea and vomiting of 2 month's duration. Physical examination revealed on the right third rib a tender mass with a diameter of 2 cm and hepatomegaly with a multi-nodular surface and red palms. There were no signs of carcinoid syndrome, such as cutaneous flushing. Laboratory examinations disclosed certain biochemical alterations; alkaline phosphatase 810 IU/l, gamma-glutamyl transpeptidase (gamma-GTP) 2090 IU/l, carcinoembryonic antigen (CEA) 23.5 ng/ml and alpha-fetoprotein (AFP) 6,800 ng/ml. Both HBs-Ag and HBs-Ab were negative. The patient died in a uremic state, with rapid increases of jaundice and ascites. Autopsy revealed gastric carcinoid with extensive metastases to the liver and the bone marrow. Tumor cells showed argyrophilia but not argentaffinity. Immunofluorescence specific for AFP was positive in the hepatocytes, particularly those adjacent to the metastatic tumor cells but not in the tumor cells, either primary or secondary. 79 cases reported in Japan of serum AFP-positive malignant tumor other than hepatocellular carcinoma and certain other malignancies of germ cell origin are reviewed and discussed.

In the five kinds of human cultured cells derived from ovarian adenocarcinoma (HOC-21), ovarian malignant teratoma (HOTC 3), carcinoma of the uterine endometrium (HEC-1B), squamous cell carcinoma of the uterine cervix (SKG-1) and choriocarcinoma (BeWo), the intracellular presence of lactic dehydrogenase (LDH), alkaline phosphatase (AlP), human chorionic gonadotropin (HCG), alpha-fetoprotein (AFP) and plasminogen activator were investigated. The results were as follows. 1) BeWo-, HOC-21-and HOTC 3-cells revealed high activity of intracellular presence of lactic dehydrogenase (LDH), alkaline phosphatase (AlP), human chorionic gonadotropin (HCG), alpha-fetoprotein (AFP) and plasminogen activator were investigated. The results were as follows. 1) BeWo-, HOC-21-and HOTC 3-cells revealed high activity of intracellular LDH in this order, however none of HEC-1B-and SKG-1-cells did. 2) The activity of intracellular AlP was higher in BeWo-cells than in HOC-21-cells. The isozymes of AlP detected in these cells were found to be heat-stable. The others revealed no activity of AlP. 3) The presence of HCG-beta was confirmed in both BeWo- and HOTC 3-cells. The intracellular levels of HCG-beta were found to be higher in BeWo- cells than in HOTC 3-cells. HCG-beta was observed to leak into culture medium not from HOTC 3-cells but from BeWo-cells. It was not detected in the other cultured cells. 4) No AFP was detected in any of these five cultured cells. 5) Plasminogen activator was detected in HOC-21, HEC-1B-and SKG-1-cells in contrast to HOTC 3-and BeWo-cells which were negative for plasminogen activator. These results suggest that the various marker substances detected in the human cultured cells originated from various carcinomas of sexual organs may reflect biological functions of these tumor cells and, furthermore, can apply as tumor markers to the clinical diagnosis of the diseases.

Thirteen breast-fed one-month-old infants with prolonged jaundice not due to known causes were included in this study. All infants were investigated at one and twelve months of age. Serum concentrations of total (TB) and conjugated bilirubin (CB), aspartate (ASAT) and alanine aminotransferase (ALAT), alkaline phosphatase (AP), alpha-1-antitrypsin (alpha-1-AT), alpha-1-fetoprotein (AFP) and the two primary bile acids; cholic (CA) and chenodeoxycholic acid (CDCA) were determined at both ages. The Pi-phenotype of alpha-1-AT was determined at the age of twelve months. The serum concentrations of TB, CB, AP and AFP were elevated at the age of one month but were normal at the age of twelve months. No changes in the serum concentrations of ASAT or ALAT were observed between one and twelve months of age, and the values were within the reference ranges. The serum concentrations of alpha-1-AT were within the reference range at both ages. Two infants were heterozygous for MZ, and they had normal serum alpha-1-AT concentrations. The serum concentrations of CA and CDCA were elevated at the age of one month and were still significantly elevated at the age of twelve months indicating that the infants had slight cholestasis at the age of one month, and that the cholestasis had largely subsided by the end of the first year of life.

The differentiation of aggregates of certain teratocarcinoma stem cell lines begins with the formation of an outer layer of primary endoderm cells characterized by the production of plasminogen activator and the absence of histochemically detectable alkaline phosphatase activity. After several days of culture these outer cells develop into a mixture of two types of terminally differentiated endoderm: parietal endoderm which produces a thick layer of underlying basement membrane and visceral endoderm which produces alpha-fetoprotein (AFP). We report here that in the presence of tunicamycin, a drug that inhibits glycosylation of N-asparagine linked glycoproteins, a primary endoderm-like cell is formed which is alkaline phosphatase negative and plasminogen activator positive. However, terminal differentiation of these cells is inhibited as manifested by the lack of accumulation of a thick basement membrane and the absence of immunologically detected AFP. Such inhibition is reversible following removal of the tunicamycin. Terminal differentiation of endoderm depends, therefore, upon N-asparagine linked glycoproteins.

The appearance and clinical significance of an atypical fraction of serum alkaline phosphatase called "biliary" have been evaluated in patients with primary liver cancer (PLC) and control subjects. The "biliary" fraction was present in all 42 PLC patients and proved to be the most sensitive of the biochemical parameters utilized. The association with alpha-fetoprotein determination allowed us to identify patients affected by hepatic pathology of neoplastic type, with a diagnostic efficiency of 92%.

A comparison of preoperative serum tumor markers (lactate dehydrogenase, lactate dehydrogenase isoenzymes, alpha-hydroxybutyrate dehydrogenase, alkaline phosphatase, aldolase, leucine aminopeptidase, cholinesterase, erythrocyte sedimentation reaction, carcinoembryonic antigen, alpha-fetoprotein, and beta 2-microglobulin) was made in 76 patients with ovarian or uterine cancer. Sixty-six patients with benign ovarian tumor served as control subjects. From analysis of each tumor marker the greatest positive results were obtained with the markers beta 2-microglobulin (57.1%), lactate dehydrogenase (53.1%), and hydroxybutyrate dehydrogenase (46.2%) for patients with carcinoma of the ovary. The use of these marker combinations in all ovarian cancer patients resulted in a marked increase of the positive rate from 57.1 to 85.2%. In stage I cases, the positive rate increased from 40.6 to 63.6%.

The serum enzyme activities of gamma-glutamyl transpeptidase (GGT), alkaline phosphatase (AP), serum glutamyl oxalate transaminase (sGOT) and serum glutamyl pyruvate transaminase (sGPT) were determined longitudinally in 51 patients with a disseminated non-seminomatous testicular tumor. Elevated levels of one or more enzymes before chemotherapy were observed in 13 patients, all with stage III disease. If, after two cycles of chemotherapy, the established tumor markers alpha-fetoprotein (AFP), human chorionic-gonadotropin (HCG) and/or lactate dehydrogenase (LDH) were normalized, the initially increased enzyme activities were declined to normal values as well. Peaking concentrations of one or more of the tumor markers during induction chemotherapy, probably due to tumor cell lysis, were found in 34 of 45 marker-positive patients (76%). In addition, increases of one or more of the investigated enzyme activities were also noticed in 20 patients. In 76% of these patients the highest point of the tumor marker concentration coincided well with that of the enzyme activities. Indications are given that the peak activities were probably not caused by liver damage. Enzyme elevations were also found in 3 out of 7 patients with progressive disease. The behaviour of the enzyme activities of GGT, AP, sGOT and sGPT in patients with a disseminated non-seminomatous testicular tumor coincided with the known tumor markers. It favors the hypothesis that these enzymes are synthesized in the tumor. The mortality amongst stage III patients with or without initially raised GGT levels differed significantly (P less than 0.02). Finally, it is concluded that in patients with a non-seminomatous testicular tumor, sGOT, sGPT, GGT and AP cannot be used to diagnose liver function.

Sex, age and 21 routine liver function assays were analyzed by stepwise selection and the best-of-all-possible-combinations method to identify a small group of assays valuable in establishing which liver cirrhosis (LC) patients have a high risk of hepatocellular carcinoma (HCC), when alpha-fetoprotein (AFP) is not elevated. Data was obtained from 115 HCC and 122 LC patients on admission. Tumor size correlated with AFP (0.73), alkaline phosphatase (ALP, 0.47), leucine aminopeptidase (LAP, 0.42), lactic dehydrogenase (LDH, 0.42), and the glutamic oxaloacetic transaminase (GOT)/glutamic pyruvic transaminase (GPT) ratio (GOT/GPT, 0.41). The mean of the correct diagnosis rates (CDR) of HCC and LC utilizing AFP as the sole parameter (89%) was markedly higher than those of the other parameters. The best-of-all-possible-combinations method presented a more powerful combination than stepwise selection. The best combination of 7 parameters (LAP, GOT/GPT, choline esterase, one-hour erythrocyte sedimentation rate, age, albumin/globulin ratio, and total bilirubin) presented a mean CDR of 80%, HCC CDR of 77%, and false positive rate of 18%. LC patients statistically diagnosed as having HCC by these 7 parameters are proposed as high risk patients. Fourteen (78%) of 18 HCC patients who were AFP-negative were statistically diagnosed. This analysis can be applied to LC patients to distinguish those that should be followed closely by imaging diagnostic techniques.
