Human placental lactogen (HPL or HCS), the beta subunit of human chorionic gonadotropin (beta-HCG), and carcinoembryonic antigen (CEA) were measured by a specific radioimmunoassay in plasma of 65 patients with ovarian cancer. Fifty-one patients had epithelial tumors, while 14 had germ cell tumors. It was found that 47 patients (72 per cent) had high levels of plasma HPL, 29 patients (45 per cent) had high levels of plasma beta-HCG, and 34 patients (52 per cent) had high levels of plasma CEA, but there was no correlation between these protein marker levels in different patients. Twenty of these patients were studied before and after operation and during chemotherapy and/or radiotherpy. There was no consistent correlation between these marker levels and the course of the disease. These data suggest that measurement of HPL, beta-HCG, and CEA in sera of patients with ovarian cancer is not of value in assessing the clinical status of the patients or in determining the effect of therapy.

Measurements of HCG and carcino-embryonic antigen (CEA) were made in 26 patients with ovarian cancer to evaluate these substances as tumour markers; 13-4 per cent of 194 CEA estimations and 14-6 per cent of 144 HCG estimations were abnormal. CEA values were abnormal in 9 out of 26 patients and HCG values in 13 out of 26 patients. The implications of these findings particularly the presence of HCG are discussed.

The significance of CEA, AFP, HCG and SP1 determinations in 85 patients with ovarian cancer were analyzed from the point of view of evaluation of the clinical status of the patients. On the basis of the trials it was stated that a satisfactory correlation between the extension of the tumor and the serum CEA level was observed in 26.6% of the cases. The efficiency of monitoring by systematic CEA tests was found to be 17.3%. The determination of AFP and HCG is useful only in cases of tumors with specific histological structures and in problems of differential diagnostics. The testing of SP1 is of no value in clinical practice.

It would be of benefit for the clinical relevance of tumor marker determination to be demonstrated, as a lot of markers are now in clinical use. Increased levels of carcinoembryonic antigen correlate with the stage of breast carcinoma. CA 15-3 should also be measured during follow-up of patients with this disease. The latest findings suggest a higher sensitivity and specificity of CA 15-3 than of CEA. The prognostic value and the usefulness of CEA measurement in screening seem to be poor. The measurement of CA 125 seems to be a reliable method for monitoring the presence and clinical behavior of ovarian cancer. It is suggested that invasive diagnostic procedures are not required in patients with normal marker levels. The management of chorion carcinoma can be determined as an ideal model in the range of marker application. Only in this disease does the marker HCG reach almost 100% sensitivity and specificity. The definition of response to chemotherapy and the appearance of relapse can be based on HCG measurement.

Tumour markers are often circulating tumour-associated indicators of tumour development. As such they are not suitable for tumour screening and localization, but valuable as adjuncts for medical follow-up care of tumour patients, where their serum level alterations may anticipate the clinical detection of tumour behaviour by a lead time of 1 to 6 months before other methods. The following tumour may be controlled by established markers: endocrine tumours by NSE, calcitonin, parathormone, 5-HIAA, catecholamines/metabolites etc.; head-neck tumours: SCC, CEA; thyroid carcinoma: TG, calcitonin; lung cancer: CEA, NSE, SCC; liver cancer: AFP (PLC), CA 19-9 (cholangiocell.), CEA (secondary): biliary tract and pancreatic cancer: CA 19-9; colorectal carcinoma: CEA, CA 19-9; squamous cell carcinoma (ENT, oesophagus, anal): SCC; breast cancer: CEA and CA 15-3; ovarian cancer: CA 125 (epithelial), CA 19-9 (mucinous); germ cell tumours (ovary including trophoblastic tumours/testes): AFP and HCG; prostatic cancer: PAP and PSA; bladder cancer: TPA.

Carcinoembryonic antigen (CEA) and alpha 1-fetoprotein (AFP) should like to be a part of the diagnostic tool of breast and ovarian cancer. HCG is an established specific tumor marker in the monitoring of trophoblastic tumors. The development of a specific HCG-beta-radioimmunoassay led off the possibility to determine the so called subclinical estimation of the tumor tissue. First clinical steps of tissue polypeptide antigen (TPA), cancer antigen 12-5 (CA-12-5), cancer antigen 15-3 (CA-15-3) and D-Dimer would be of great interest to study the correlation between serum concentrations and tumor mass. The following classification is showing other tumor markers in a general review, too dividing molecules produced from the tumor cell itself, so called tumor derived products, and on the other side tumor associated products accompanying the malignancy.

The levels of total protein, Ig, AFP, beta-HCG, CEA, SC, SP1 and alpha 2-PAG were measured in cystic and peritoneal effusions obtained from 70 females with benign and malignant ovarian tumors. This study was carried out to test out parameters those are useful for tumor monitoring of ovarian cancer. Our results indicate that determining CEA in peritoneal effusions could be one of useful methods in tumor monitoring of mucinous cystadenocarcinomas in cases of known histology and praetherapeutic estimated CEA levels in cystic or peritoneal effusions. Our results demonstrate that CEA-levels greater than 100 micrograms/l are mostly found in mucinous cystadenocarcinomas and in mucinous cystadenomas, too. High cystic CEA levels support the histology aiming for demonstration of mucinous component.

Two hundred and eighty-six patients presenting with metastatic adenocarcinoma or undifferentiated carcinoma whose primary site was not identified by clinical history, physical examination and chest radiograph have been studied. Median survival from presentation was 22 weeks. Factors independently predicting improved survival were lymph node presentations, good performance status and body weight loss of less than 10 per cent. In 88 (31 per cent) patients the primary tumour site was subsequently identified, in 58 (20 per cent) during life. Lung cancer was the most frequently identified primary tumour, and in only 32 (11 per cent) of the patients was a 'treatable' primary tumour (i.e. germ cell, breast, ovarian, prostate, thyroid cancer or lymphoma) identified. Among the treatable primary tumours were those in eight out of 16 female patients presenting with axillary metastases who were subsequently shown to have primary breast cancer and four of 13 females presenting with ascites who were found to have primary ovarian cancer. Prostatic cancer was confirmed in five out of 13 men with raised serum acid phosphatase. Of 22 patients with elevated serum alphafoetoprotein (AFP) or beta-human chorionic gonadotrophin levels (beta HCG) 18 had some features of the 'atypical teratoma syndrome'. Of the total of 32 patients with treatable tumour types, 29 (90 per cent) were identified during life. Median survival for patients with treatable tumour types identified during life was 104 weeks, compared with 22 weeks for the group as a whole. Retrospective immunocytochemical staining of the original biopsy showed that prostatic specific antigen and antibodies to beta HCG and AFP were diagnostically useful, but a series of organ site non-specific markers of histogenesis or cellular differentiation (carcinoembryonic antigen, secretory component for IgA, peanut lectin binding, epithelial membrane antigen and keratin) showed no significant correlations with identified primary sites, responsiveness to empirical chemotherapy or survival. Metastatic undifferentiated carcinoma or adenocarcinoma from an unknown primary site represents 6.5 per cent of all referrals to the medical oncology unit, Royal Prince Alfred Hospital, Sydney. We offer guidelines for the rapid identification of the limited number of primary sites for which effective and specific forms of systemic treatment are available.

Human chorionic gonadotropin (hCG)-like molecules have been reported to be elevated in a substantial fraction of serum samples from patients with various gynaecologic tumours and have been discussed as possible markers in these malignancies. Employing highly sensitive and specific immunoradiometric assays, we determined total hCG-related immunoreactivity (hCG/hCG beta), as well as free alpha-subunit (alpha-SU), common to all glycoprotein hormones, in serum (n = 106) and malignant effusions (n = 26) of women with gynaecologic malignancies. For comparison, we also measured hCG/hCG beta in nonmalignant ascitic fluids (n = 21). HCG/hCG beta serum levels were elevated (> 5 IU L-1) in 39 of 106 patients (37%) with gynaecologic malignancies, whereas free alpha-SU was above normal range only in seven (6.6%). Frequencies of hCG/hCG beta elevations were similar in women with endometrial, (n = 39), cervical (n = 40) and ovarian (n = 27) cancer, being 30%, 35% and 41%, respectively. In malignant ascites (n = 15) and tumour cyst fluids (n = 11) of patients with ovarian cancer, hCG/hCG beta concentrations were significantly higher than in the corresponding serum samples and benign ascitic samples. Free alpha-SU, on the other hand, was increased in only one of 26 malignant effusions. In conclusion, hCG/hCG beta is frequently elevated in serum of patients with endometrial, cervical and ovarian cancer and may serve as a tumour marker in these malignancies, particularly in patients where other markers are negative. In this respect, analysis of ascitic or tumour cyst fluids may be of higher diagnostic value as serum measurements.

Pleuropulmonary metastasis occurs in 30 to 50% of all patients with cancer. Certain metastases occur specifically in females: breast and ovary cancer. There are six different clinical presentations of bronchopulmonary metastases: unique or multiple nodular images, mediastinal nodes, carcinomatous lymphangitis, bronchial metastasis, tumoral emboli, and metastatic bronchiolo-alveolar metastatic cancer. When the primary cancer is not known, a minimum number of investigations are needed: thyroid and pelvic ultrasound, mammography, colonscopy for certain cases, alfa-fetoprotein assay, neuron-specific enolase and beta HCG. Metastatic pleurisy accounts for 45% of all cases of pleurisy. In women, neoplastic pleural effusions result from breast cancer (37%), genitourinary tract cancer (20%), and lung cancer (15%).
