Combinations of carcinoembryonic antigen (CEA), gamma glutamyl transpeptidase (GGT), pregnancy-associated macroglobulin (PAM) and placenta-like alkaline phosphatase (PLAP) were studied in groups of patients with ovarian and cervical cancer. In ovarian cancer, only CEA and PLAP levels appeared to reflect tumor burden and were complementary in detecting active disease. In cervical cancer, CEA and GGT reflected tumor burden, while PLAP showed just the reverse--the highest degree of positivity being present in minimal disease. PLAP positivity was even more pronounced in patients with cervical dysplasia and carcinoma in situ while CEA and GGT were negative. The data indicate that the use of marker combinations can improve our capacity to detect minimal disease and provide information regarding tumor biology that may not be available by studying individual markers or by other means. It remains to be determined whether the use of tumor markers can influence existing therapy sufficiently to alter the outcome in cancers which are notoriously difficult to treat.

Intestinal metaplasia is often associated with human gastric carcinoma. Intestinalization seems to be a typical example of abnormal differentiation and is possibly a precancerous state. For investigation of intestinal metaplasia, a method for visualizing disaccharidases using Tes-Tape was developed; this method was applied to many specimens of stomach surgically removed for the treatment of gastric carcinoma. More than 130 specimens of human stomach were investigated. Intestinalization was classified into types I and II intestinal metaplasia. In type I intestinal metaplasia, sucrase, maltase, trehalase, alkaline phosphatase, goblet cells, and Paneth cells were present; while the type II intestinal metaplasia, sucrase and maltase were present but alkaline phosphatase and trehalase were absent. In type II, goblet cells were present but not Paneth cells. The histochemical technique for sucrase was newly devised. Some of the villi with goblet cells in the area of intestinalization in the stomach were not stained by sucrase activity, although most of the villi were stained. The presence of a third type of metaplasia was suggested. Purified sucrases obtained from the intestine and one case of type I intestinal metaplasia showed blood group reactivity due to the oligosaccharide side chain. However, purified sucrases obtained from two cases of type II intestinal metaplasia were negative in blood group reactivity. A close relation between distribution of alpha-fetoprotein and carcinoembryonic antigen in gastric carcinoma and that in surrounding intestinal metaplasia is discussed.

Serum protein electrophoresis (SPE) and immunoglobulin levels were studied in 50 patients with breast carcinoma before therapy (17 with stage I disease; 18 stage II; 15 stage III or IV), and in 55 patients after primary lesions were surgically removed and gave no evidence of recurrence. The most consistent and statistically significant abnormalities observed on SPE were those of albumin, globulin, and alpha-2 globulin. Patients who were free of disease during follow-up examinations had higher albumin and lower globulin and alpha-2 globulin levels than those with advanced breast cancer (P = 0.003, P = 0.03, and P = 0.001 respectively). There was no difference in concentrations of immunoglobulin G, A, or M among the 5 groups. Routine laboratory tests of hemoglobulin, lymphocyte count, calcium, alkaline phosphatase, creatinine phosphokinase, lactic dehydrogenase, and transaminase also did not differ among the groups, but carcinoembryonic antigen was significantly elevated in patients with stage III and IV disease.

Nineteen biochemical parameters, most of which have been individually advocated as tumour-index-substances for breast cancer, were measured in 51 patients with breast disease, 42 of whom had active breast cancer. Seven of these parameters were raised in more than half of the 17 patients of the series with overt metastases; these were serum ferritin (88%), C-reactive protein (87%), carcinoembryonic antigen (81%), acid glycoprotein (75%), total alkaline phosphatase (64%), sialyl transferase (56%), andthe urinary hydroxyproline/creatinine ratio (73%). The incidence of biochemical abnormalities in patients in this group compared favourably with the results of physical methods of detecting metastases. 7 of 16 further patients without evidence of distant metastases, but who had a poor prognosis as judged by histology of the primary tumour and axillary lymph-nodes, had abnormalities of at least one of the seven parameters. 3 of these patients have relapsed within a year of mastectomy. The results suggest that these biochemical tests could assist in monitoring metastatic disease and could indicate at the time of mastectomy, patients who might benefit from immediate systemic therapy in addition to local treatment of their breast carcinomas.

Two human endodermal sinus tumours (yolk sac tumours) were transplanted successfully into nude mice. The transplanted tumours maintained not only morphological characters, such as Schiller-Duval bodies, but also the ability to synthesise alpha-fetoprotein, lactic dehydrogenase 1, liver and bone type alkaline phosphatase, and some human serum proteins. Since these tumours produced lactic dehydrogenase 1 but not the other four isozymes of lactic dehydrogenase, this isozyme, like alpha-fetoprotein, seems to be a good marker for the diagnosis and management of cases of endodermal sinus tumour. One of the two tumours produced another fetal antigen or carcinoembryonic antigen in addition to alpha-fetoprotein. These two endodermal sinus tumours, with their various markers in nude mice, will be useful in studies on diagnostic markers.

Two cases of liver metastases from gastric carcinoma are described in which the simultaneous occurrences of alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA) and carcinoplacental alkaline phosphatase (CPALP) were demonstrated in the sera and tumor tissues. AFP was detected not only in the tumor tissues but also in the liver tissue adjacent to the tumor, while the other 2 carcinoembryonic proteins were not detected in the non cancerous liver tissues. The characteristics of CPALP in Case 1 were almost similar to the Nagao isoenzyme, based on enzyme tests involving L-leucine, L-phenylalanine and EDTA inhibitions, heat-stability and Michaelis constant, except for electrophoretical slower moving, while that in Case 2 were identical to variant type CPALP (Warnock).

Isoenzyme V of 5'-nucleotide phosphodiesterase (5'-NPD-V) is present in the peripheral sera of patients with hepatic metastases. A total of 122 patients underwent prospective serologic analysis followed by operation for primary tumors of the gastrointestinal tract and careful evaluation of the liver. A positive 5'-NPD-V assay was found in fifty-nine of sixty patients with liver metastases. A negative 5'-NPD-V assay was found in forty-three of sixty-two patients with no evidence of hepatic metastases. The accuracy of the test was 84 per cent, and the predictive value was 75 per cent. Serum 5'-NPD-V was abnormal significantly more frequently in patients with metastatic liver disease than were liver scans or carcinoembryonic antigen (CEA), alpha fetoprotein, serum glutamic oxalacetic transaminase (SGOT), and total serum bilirubin or serum alkaline phosphatase levels.

The recent reports of the use of serum and tissue enzyme assays in primary diagnosis and then in following the course of the disease have been reviewed. These include use of bone marrow acid phosphatase, isoenzymes of both acid and alkaline phosphatase, LDH5/LDH1 ratios, sialyltransferase and the combination of carcinoembryonic antigen with serum enzyme assays to help in prediction of the occurrence of hepatic metastases.

The mean plasma carcinoembryonic antigen (CEA) level was found to be significantly increased in 66 patients with alcoholic liver disease (4.4 micrograms/1) compared with the mean CEA level in 164 healthy blood donors (1.6 micrograms/1, p less than 0.001). Eighteen of the patients (27%) had values above our upper normal values of 5 micrograms/1, compared with 3 of 41 (7%) in a group of patients with non-alcoholic liver diseases. On the other hand, the mean CEA values in the two groups did not differ significantly. The CEA level remained unchanged in patients who continued drinking. However, in 20 patients who stopped drinking, the mean CEA levels dropped significantly from 6.6 micrograms/1 to 3.7 micrograms/1. Concomitant fluctuations were seen in CEA, gamma-glutamyltranspeptidase (gamma-GT), asparate aminotransferase (ASAT), and alkaline phosphatase, although a significant correlation was found only between CEA level and the level of gamma-GT (r = 0.32, p less than 0.02). The correlation between CEA and gamma-GT was best in 41 patients without complicating disorders (r = 0.55, p less than 0.001). CEA was significantly increased in patients with complicating disorders. Much of the increase of CEA in many patients with alcoholic liver disease might be secondary to complicating disorders in the respiratory and/or gastrointestinal tracts. This could possible explain why patients with alcoholic liver disease more often than other patients with benign diseases have elevated CEA.

Serial plasma carcinoembryonic antigen (CEA) levels were determined in 84 patients with breast cancer who were receiving postsurgical adjuvant chemoimmunotherapy or adjuvant chemotherapy. CEA values were correlated with clinical status, scintiscans, alkaline phosphatase, LDH, and SGOT. CEA values greater than 2.5 ng/ml were considered abnormal. Thirty patients had normal serial CEA values; all remain disease-free. In 54 patients one or more abnormal CEA values were recorded; nine of 54 developed overt metastatic disease. Relapses occurred in four of 38 patients in whom values up to 5 ng/ml were recorded, in three of 14 patients in whom values up to 10 ng/ml were recorded, and in two of two patients in whom values greater than 10 ng/ml were recorded.
