Regan isoenzyme, variant alkaline phosphatase, and alpha-fetoprotein were found in the serum of a patient with gastric cancer. The histology of the tumor was tubular adenocarcinoma. There were metastases in the retroperitoneal lymph nodes, but not in the liver. The liver was normal microscopically, with no evidence of bile duct obstruction. alpha-Fetoprotein in the tumor tissue was detected by immunoprecipitation reaction in agar. Regan isoenzyme and variant alkaline phosphatase were also detected in the tumor tissue and total alkaline phosphatase activity of the tissue was very high. These findings suggested their tumor origin.

Carcinoembryonic antigen (CEA), alpha-fetoprotein (AFP), and carcinoplacental alkaline phosphatase (CPALP) were detected simultaneously in the sera and body fluids of two male patients with gastric carcinoma matestatic to the liver. At autopsy, widely disseminated gastric cancer of Borrmann III type with liver metastases was revealed in both bases. Histologically, they were moderately differentiated tubular and papillary adenocarcinomas with marked cellular atypia and necrosis. In Case 1, the properties of CPALP were identical to Nagao type CPALP, and in Case 2 the Variant type CPALP. Using immunofluorescence, CEA and CPALP were demonstrated in both primary and metastatic cells. However, only in Case 2 was AFP observed in some of the primary tumor cells.

Using the simple thin layer polyacrylamide gel electrophoresis, serum alkaline phosphatase could be separated 5 isozyme bands in various digestive diseases, consisting of 54 cases of gastric cancer, 11 of colonic cancer, 12 of hepatoma, 4 of cholangioma, 14 of pancreatic cancer, 81 of benign hepatobilliary diseases, 13 of cancers of other organs and 61 of control. The obtained results were as follows: 1) The electrophoretic analysis of serum alkaline phosphatase showed the specific band remaining at the origin, already reported as "alkaline phosphatase O", in primary and metastatic cancer of the liver and cholelithiasis. On the contrary, alkaline phosphatase O was never found in gastric and colonic cancer without cholelithiasis. On the contrary, alkaline phosphatase O was never found in gastric and colonic cancer without cancerous metastasis to the liver, and it was also inclined to be positive with the progress of liver metastasis among them. 2) Intestinal alkaline phosphatase was usually found in higher frequency in blood group B and O than in the others, and it was apt to disappear in gastric or colonic cancer with an exacerbation of its cancerous lesions. 3) Heat-stable alkaline phosphatase was found in 10% of gastric or colonic cancer, all of which were histologically proved to be well differentiated adenocarcinoma.

Histological and histochemical studies of stomach cancer and comparisons of characteristics of highly differentiated adenocarcinoma (24 observations) and nondifferentiated cancer (51 observations) revealed no differences in the character of the secret and in the activity of alkaline phosphatase in tumoral cells of glandular and nondifferentiated cancer. At the same time different localization of primary cancer was established: nondifferentiated cancer--in the region of glandular necks and basal parts of the mucosa, adenocarcinomas--in the surface regions. Comparison of the data obtained with features of physiological regeneration of the epithelium of the gastric mucosa justifies the assumption that foveate epithelium of nondifferentiated cancer, epithelium of the glandular neck, was the source of origination of adenocarcinoma. A different histogenesis of adenocarcinoma and nondifferentiated cancer accounts for their morphological differences and characteristics of the clinical course.

The enzymological and immunological properties of alkaline phosphatase (ALP) isoenzymes in intestinal metaplasia and gastric carcinoma tissues were compared with those of purified human intestinal, placental, and hepatic ALP's to speculate the gene expression of gastric cancer cells. The results were as follows: Intestinal metaplasia was found in 21 of 23 cases (91%) of gastric cancer, whereas normal gastric mucosa had no ALP activity. ALP extracted from the mucosa of intestinal metaplasia was identical with intestinal ALP as to enzymological and immunological properties. ALP obtained from gastric carcinoma tissues of 23 patients was separated into 3 bands (ALPa, ALPb, and ALPc) by polyacrylamide-gel disc electrophoresis. Ten cases showed ALPa only, 4 cases showed ALPa and ALPb, 5 cases showed ALPa and ALPc, and the other 4 cases showed ALPa, ALPb, ALPc, respectively. It was concluded that ALPa was similar in its enzymological and immunological properties to hepatic-type ALP, ALPb was similar to placental-type ALP, and ALPc was similar to intestinal-type ALP, ALPb probably originates from the cancer cell itself. As for the other enzymes, ALPa and ALPc, further investigation should be made to determine whether they come from the cancer cell itself or not.

Glycylprolyl beta-naphthylamidase activities in sera from 40 normal subjects (18-81 years) were: 22.6 +/- 0.9 (S.E.) (11.8-38.2) I.U./1 serum at 37 degrees C. The enzyme activities did not differ significantly with age between the younger group under 40-years-old and the older group over 40-years-old. Males, especially under 40-years-old, had slight but significantly higher activities than females. The levels were decreased in patients with gastric cancer. The levels were elevated in patients with hepatobiliary diseases, and had significant correlations with the results of the serum tests in hepatic diseases such as glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase, alkaline phosphatase and total bilirubin, but had no correlation with serum lactate dehydrogenase. In cellulose acetate electrophoresis, normal sera had a single peak at the beta-globulin region, but the sera in hepatitis or liver cirrhosis showed not only an increase in the normal peak at the beta-globulin region but also the appearance of the other one or two new peaks in the alpha1 and alpha2-globulin regions.

The occurrance and significance of important carcinofetal antigens other than AFP and CEA are reported. These included the alpha 2 H-protein which is produced in the liver and increases in serum of patients with various tumors, the fetal sulphoglycoprotein antigen FSA from the gastric juice of patients with gastric cancer, the carcinoplacental alkaline phosphatase (REGAN-isoenzyme)which is found in the serum of patients suffering from e.g. bronchogenic, mammary, urogenital and gastrointestinal carcinomas, the beta-S-fetoprotein which is most likely to be identical with C-reactive protein, gamma-fetoprotein, the carcinofetal antigen in glial tumors (CFGA); ectopic production of placental hormones like human gonadotropin, placental lactogen, plasminogen-activators; leukemia-associated antigens. Furthermore, some other less known carcinofetal antigens are mentioned.

Monoclonal antibodies (Mab) are potent probes to identify individual tumour cells or small tumour cell clusters in bone marrow. In the present study, various antibodies directed against either cell surface or intracytoplasmic antigens of epithelial cells were assessed for their ability to detect such cells in bone marrow of patients with breast, colorectal and gastric cancer. According to the presented data, monoclonal antibodies against intracellular cytokeratin (CK) components are superior in terms of specificity and sensitivity to antibodies reacting with epitopes of the cell membrane. Using a monoclonal antibody against the cytokeratin polypeptide 18 in connection with the alkaline phosphatase anti-alkaline phosphatase detection system (APAAP), we could detect tumour cells in bone marrow of 34 out of 97 patients with gastric cancer examined at the time of primary surgery. The incidence of positive findings was correlated to established risk factors, such as histological classification and locoregional lymph node involvement. Clinical follow-up studies on 38 patients demonstrated a significantly increased relapse rate in patients presenting with CK-positive cells in their bone marrow at the time of primary surgery. Thus the described technique may help to identify patients with gastric cancer carrying a high risk of early relapse.

Reported are 2 cases of an advanced gastric cancer with a "diffuse carcinomatosis of the bone marrow" (DCMB) showing a widespread osteoplastic bone metastasis. In a DCBM, a widespread invasion of cancer cells to the bone marrow occurs, causing leukoerythroblastosis, anemia, and disseminated intravascular coagulation. The local reaction in the bone, namely being osteoplastic or osteolytic, has not been discussed in previous papers. Our cases were characterized by an extremely high serum alkaline phosphatase, a "superscan" view of the bone scintigram, and a diffuse osteoplastic bone metastasis with an osteoid increase. Thus we think there are DCBM subtypes with a diffuse osteoplastic bone metastasis.

An unusual alkaline phosphatase (AP), named HuG-AP, was found in a newly established cell line (HuG-1) derived from a patient with stomach cancer. The enzyme was purified about 300-fold by affinity chromatography. On polyacrylamide gradient (4-30%) gel electrophoresis, the one band with the enzyme activity was observed. The enzymic properties of HuG-AP did not conform to those of liver, intestinal, placental, and germ cell AP isoenzymes which were recognized as homodimeric structure. Thermostability of the HuG-AP showed an intermediate value between intestinal and placental APs. Immunologically, the HuG-AP reacted with both anti-intestinal and anti-placental AP monoclonal antibodies. Dot blot analysis showed that both intestinal and placental AP mRNAs were expressed in HuG-1 cells concurrently. Therefore, we concluded that this novel AP had a hybrid form, namely heterodimeric structure, consisting of one subunit each of intestinal and placental APs. However, all of the properties of this hybrid AP did not conform to the intermediate enzymic properties between intestinal and placental APs which would be shown when they both coexist. Because an AP identical to HuG-AP had already been found in the metastatic lesion of the liver of the same patient, the expression of this novel AP seemed to occur in the patient's original cancer cells but did not result from spontaneous transformation of cultured cells.
