The development of new and effective marker substances has optimized tumor-marker-guided follow-up programs to monitor generalization of disease and to assess the therapeutic outcome. Isoferritins of placental origin were first determined in the serum of patients with lymphoproliferative disease by way of the recently developed monoclonal antibody CMH-9. We have set up an Austro-Israeli working group and analysed 64 patients in terms of the sensitivity of placental
ferritin
(PLF) compared with the standard markers
carcinoembryonic antigen
(
CEA
) and mucinous-like cancer-associated antigen (MCA) in patients with metastatic breast cancer. We have additionally evaluated the importance of combined marker determination. Analysis of the data in view of site of metastatic spread yielded satisfying results both for PLF (sensitivity 70.4%) as well as MCA (sensitivity 76.9%) for visceral metastases; a combination of these two markers revealed a striking sensitivity of 88.4%, which, however, could not be improved by adding the third marker (
CEA
). With regard to non-visceral metastases,
CEA
and MCA were clearly superior.

Blood levels of
carcinoembryonic antigen
(
CEA
), alpha-fetoprotein,
ferritin
, ACTH. triiodothyronine and thyroxin were measured by radioimmunoassay in 217 cases of lung, hepatopancreatoduodenal and colonic cancer, 61 patients with nontumor pathology of those sites and in 37 healthy controls.
CEA
proved the most reliable marker of lung and colonic cancer and tumor-related mechanical jaundice, its lowest concentration in 65-100% of cancer patients exceeding the highest levels observed in controls. In the colorectal group,
CEA
level returned to normal after radical surgery and rose again at recurrence or distant metastases. Ferritin, cortisol and ACTH appeared less efficient.

The distribution of
carcinoembryonic antigen
(
CEA
) and
ferritin
was demonstrated by immunohistochemical method in 95 patients with normal, hyperplastic, and neoplastic endometrium in order to distinguish among these conditions. Fifteen patients with normal endometrium (NE), 28 with hyperplasia (AH), 12 with atypical hyperplasia (AAH), and 40 with endometrial carcinoma (CA) were studied. Paraffin section tissues were subjected to immunostaining according to the avidin-biotin complex method.
CEA
was found in 33% of NE cases, 46% of AH, 75% of AAH, and 83% of CA (P less than 0.01). Ferritin was not detected in any case of NE; however, it was detected in one case (4%) of AH, in one case (8%) of AAH, and in 88% of CAs (P less than 0.001). Both tumor markers exhibited a heterogeneous staining pattern, and for a given histologic hyperplastic or malignant lesion, corresponded to several phenotypes. There was no significant correlation between clinical stage or tumor grade and
CEA
or
ferritin
expression. In conclusion,
ferritin
seems to be a better biological marker than
CEA
in distinguishing between hyperplastic and neoplastic endometrial lesions and it is also more reliable than
CEA
for endometrial malignancy since it was absent in normal and hyperplastic endometria.

Retrospective analysis previously identified significant elevation of five tumour markers,
carcinoembryonic antigen
(
CEA
),
ferritin
, orosomucoid. C-reactive protein and erythrocyte sedimentation rate (ESR), in patients with systemic breast cancer and showed that changes in each of these markers individually correlated significantly with therapeutic response. In this study we have prospectively tested these findings. None of the five markers was significantly elevated in primary breast cancer compared to normal control or benign breast disease groups. They therefore appear to have no role either in screening or in the differential diagnosis of breast cancer. There was a significant elevation of all five markers in patients with systemic breast cancer (P less than 0.0001: analysis of variance) but sequential changes in
CEA
and ESR only correlated significantly with the UICC-assessed response. Prospective confirmation of the correlation between changes in serum
CEA
and ESR provides the basis for using these markers in the assessment of response to therapy in patients with systemic breast cancer.

Some characteristics of cell biology and the production of various tumor markers were examined using 8 human ovarian cancer cell lines of epithelial origin. Structural abnormalities of chromosomes 1, 3, and 6 were relatively common karyotypic changes among the cell lines. Cytoplasmic estradiol or progesterone receptor was not detected in any of the cell lines. A significant heterogeneity of the production of various tumor markers (
ferritin
, tissue peptide antigen,
carcinoembryonic antigen
, carbohydrate antigens 125, and 19-9) was noted among the cell lines grown in culture medium supplemented with serum. Three of the 8 cell lines were adapted to proliferate in completely synthetic serum-free culture medium. In addition to marker substances described above, small amounts of progesterone or human chorionic gonadotropin were produced in 2 of the 3 cell lines grown in serum-free culture medium. These results indicate that various marker substances including tumor markers are not produced consistently by human ovarian cancer cells of epithelial origin.

Serum levels of total sialic acid,
carcinoembryonic antigen
(
CEA
),
ferritin
, lactate dehydrogenase, and creatine phosphokinase were measured both in tumor drainage blood (axillary vein) and in peripheral blood obtained from 121 breast cancer patients during surgery. No significant differences between mean values in peripheral and tumor draining blood, between cancer patients and healthy controls, or between patients with or without axillary lymph node metastases were found for any of the markers. Both
ferritin
and
CEA
levels were higher in axillary and peripheral blood from patients with central breast cancer versus other sites but the difference was significant only for
CEA
(p less than 0.05).
CEA
levels were significantly higher (p less than 0.01) in patients with greater than 2 cm diameter carcinomas versus T1 stage patients in axillary but not in peripheral blood. When the cephalic vein was clamped before the axillary sample was taken,
ferritin
showed a significant increase (p less than 0.05). We conclude that measurement of sialic acid,
CEA
, and
ferritin
in axillary venous blood in breast cancer patients is not of clinical benefit, although further data are needed to clarify whether other advantages can be derived.

Carcinogenic metal levels in serum and tissue samples were measured in patients with bronchopulmonary or colorectal cancer. The cadmium and nickel tissue levels in the patients with lung cancer were significantly higher than in the controls. A statistical correlation was found between chromium and cadmium, as well as between cadmium and nickel in patients with colorectal cancer. In addition, prior to the operation, the tumor markers alpha-fetoprotein (AFP),
carcinoembryonic antigen
(
CEA
), carbohydrate antigen (Ca 19-9), polypeptide histidio antigen (TPA) and
ferritin
were analyzed. Their average concentrations were correlated with the existing concentrations of the metals. This was done for both types of cancer. Tumor marker detection showed an increase of
CEA
and TPA in patients with colorectal cancer. A statistical correlation was observed between AFP and zinc tumor tissue.

A series of tumour related markers have been examined in 179 patients receiving primary endocrine therapy for metastatic breast cancer. Significant correlations between therapeutic response (UICC criteria after 6 months of treatment) and appropriate alterations in serum concentrations of
carcinoembryonic antigen
,
ferritin
, c-reactive protein, orosomucoid and the erythrocyte sedimentation rate, have been observed when changes in these markers were examined only at high serum concentrations. By combining these five markers a 'therapeutic index' of response has been devised which can be employed at an early stage of treatment in more than 90% of patients, giving an overall sensitivity/specificity of 90%/78% for therapeutic response or disease stabilisation over a 6-month period. The design of an objective measurement of response, which is easy to perform, has the potential to replace the existing, largely subjective. UICC criteria for retrospective judgement of response, and may also be used to direct systemic endocrine therapy.

Using Prolifigen TK kit "Daiichi", the serum TK level were determined in patients with adult T-cell leukemia (ATL) and its related disorders. The mean level of serum TK at diagnosis was 279.9 U/l in acute type ATL, 27.8 U/l in chronic type ATL, 59.0 U/l in lymphoma type ATL, 3.1 U/l in pre-ATL and 2.4 U/l in HTLV-I carriers. In these patients, six other kinds of tumor markers such as lactic dehydrogenase, beta 2-microglobulin, immunosuppressive acidic protein,
ferritin
, tissue polypeptide antigen and
carcinoembryonic antigen
were also examined. Among the seven tumor markers, TK level showed the most significant difference among clinical subtypes of ATL. This indicates that the TK level is one of the promising parameters indicative of aggressiveness of ATL cells.

The paper is concerned with an assay of tumor markers in rectal cancer patients. The
carcinoembryonic antigen
has been shown to be the most specific marker characterizing the degree of tumor dissemination, particularly in metastatic liver lesion. Preliminary results suggest a possibility of the use of the determination of the
ferritin
level for this purpose whereas the use of the marker like alpha-fetoprotein in this group of patients is not desirable.
