A radioimmunometric assay was developed from P3 lung carcinoma target cells to detect anti-lung cancer antibodies. Of 100 sera from lung cancer patients tested, 80 (80%) were positive. However, only 6/30 (20%) sera from cancer patients with other cancers, 1/25 (4%) of sera from patients with nonmalignant lung disease, and 0/20 sera from healthy donors were positive. Quantitative absorptions showed that sera from lung cancer patients cross-reacted with other lung cancers, gastrointestinal cancers, and/or fetal lung tissues, but not with breast carcinomas, melanomas, sarcomas, fetal skin, or normal lung tissues. Two lung cancer antigens were defined: LCA-1, which shared antigenic determinants with GI tumors and fetal lung tissues, and LCA-2, which showed cross-reactivity only with GI tumors.

The diagnostic value of serum concentrations of squamous-cell carcinoma (SCC) antigen was evaluated on 48 untreated patients with squamous-cell carcinoma of the lung or oro-maxillo-facial region. To test for specificity SCC antigen was also looked for in 55 patients with various other epithelial neoplasms, in 18 with inflammatory lung disease, and in 43 with liver and 34 with renal function abnormalities. The sensitivity rate of SCC antigen in squamous-cell carcinoma of the lung was 53%, in carcinoma of the oromaxillofacial region 34%. Both groups differed significantly from all other groups, except for patients with abnormal renal function more than half of whom had raised serum concentrations. The proportion of false-positive SCC values was 11% each for patient with inflammatory lung disease and other epithelial neoplasias, and 7% for patients with abnormal liver function. SCC is not a specific marker for squamous-cell carcinoma. Its clinical value probably lies mainly in monitoring the course of such tumours.

N-isopropyl-p-[123I]-iodoamphetamine (123I-IMP) was examined for its relevancy as a labeling medium of lung scintigraphy in 30 patients with lung diseases and 20 healthy subjects. Lung diseases were classified into carcinoma and diffuse lung disease, and the all subjects with normal lung were classified into smokers and nonsmokers. To assess the reduction curve of 123I-IMP, mean transit time was calculated. Forced spirography was performed and spirographic values were analyzed. Spirographic parameters examined were vital capacity percent (%VC), forced expiratory volume in 1 sec divided by forced vital capacity (%) (FEV1.0%), and blood gas data. In the correlation matrix, the mean transit time was correlated with blood gas data, and not with %VC or FEV1.0%. In patients with lung diseases, the mean transit time was significantly prolonged; however, the difference was not significant between groups of carcinoma and benign disease, and between groups of smokers and nonsmokers. Wash-out images were obtained by the subtraction technique using the first frame image and 100-min delayed image. In patients with lung carcinoma, 87.5% of the tumors were depicted on wash-out images. The lesions were also depicted well in benign lung diseases. But among findings of wash-out image by 123I-IMP, air trapping image by 133Xe study and XCT study, there are some discordances to be clarified.

Plasma calcitonin and 6-oxo-Prostaglandin-F1 alpha (6-oxo-PGF1 alpha), one of the stable metabolite of prostacyclin, were determined in patients with malignant and non-malignant diseases of the lung. 11 out of 14 patients with small cell carcinoma and only 3 out of 17 patients with other histological types of lung cancer had abnormally elevated plasma calcitonin levels. 6-oxo-PGF1 alpha levels were significantly higher in patients with different types of lung cancer, compared to a control group with non-malignant lung disease. Combining the results of calcitonin and 6-oxo-PGF1 alpha measurements led to improved specificity and efficiency for the correct differentiation between small cell and non-small cell carcinoma of the lung; the predictive value for the diagnosis of small cell carcinoma approached 90%.

A specific radioimmunoassay for carcinoembryonic antigen was used to investigate aspects of its measurement in lung disease. The results confirm that serum carcinoembryonic antigen concentrations are higher in healthy smokers and patients with chronic obstructive bronchitis than in healthy non smokers (p less than 0.01). Corticosteroid treatment reduced the concentration in nine patients with bronchitis (p less than 0.05). Other inflammatory lung diseases (bronchiectasis, pneumonia, fibrosing alveolitis) are not associated with a raised serum carcinoembryonic antigen concentration. The sputum concentrations were about 100 times those found in serum and there was a positive correlation (r = 0.611 2p less than 0.01) between the concentrations in sputum and serum in patients with bronchitis. No preferential rise in sputum concentration was found in current smokers or patients with lung carcinoma (n = 16). A higher ratio of carcinoembryonic antigen to albumin concentration (p less than 0.05) was, however, found in lavage fluid obtained from the tumour site than in fluid from "normal" lung in the same patients, suggesting an increase in carcinoembryonic antigen secretion in the vicinity of the tumour. Despite this "local" effect the sputum concentration does not, however, appear to be a useful marker of lung carcinoma and the measurement could not be used as a screening test.

Immunoreactive ACTH was found in almost all tissue extracts of lung carcinoma from patients without clinical evidence of Cushing's syndrome; i.e. 14 of 15 primary tumors, nine of nine metastatic lymph nodes, and four of four metastatic liver nodules contained immunoreactive ACTH. The incidence of ACTH in extracts of other tumor types was much lower. Comparable normal tissues contained no detectable ACTH. Immunoreactive growth hormone, parathyroid hormone, or gastrin was not found in the same carcinoma tissue. The predominant form of ACTH in the tumor extracts was big ACTH. In pituitary extracts little ACTH predominated.53% of 83 patients with lung carcinoma had afternoon plasma ACTH levels greater than 150 pg/ml; more than 90% of plasmas containing less than 150 pg/ml were obtained from patients who had received radiation therapy or chemotherapy. 31% of 45 patients with chronic obstructive pulmonary disease (COPD), 28% of 25 patients with other severe lung disease, and 6% of 33 controls had elevated values. Big ACTH predominated in the plasma of patients with lung carcinoma or COPD having elevated ACTH levels. Tissue from the lung of a smoking dog with atypical histologic changes contained immunoreactive ACTH, almost exclusively in the big form, while tissue from another smoking dog that was histologically normal contained no ACTH. Thus ACTH may be present even in precancerous lung lesions. These studies suggest that serial plasma ACTH levels may be of value in screening for, and/or management of, patients with carcinoma of the lung.

We report here sensitive and specific measurement of immune responses of patients with certain kinds of carcinoma toward the physically and chemically well defined T antigen isolated from healthy human erythrocytes. Over 90% of adenocarcinoma tissues tested possess T-specific immunoreactive structures as determined with human antisera, in contrast to healthy tissues and benign lesions. Adenocarcinoma patients recognize the carcinoma-associated T antigen as foreign. Delayed-type skin hypersensitivity reaction to T antigen (DTHR-T) was positive in all 25 lung adenocarcinoma patients tested, in 88% of 101 patients with ductal, in 43% of 30 patients with lobular or tubular breast carcinoma and in 9/9 patients with adenocarcinoma of body cavities. Patients of all Stages reacted positively. All 7 patients with small cell lung carcinoma and 3/5 with malignant melanoma had a positive DTHR-T. None of 17 patients with malignant brain tumors, leukemia or Hodgkin's disease, sarcoma or thyroid carcinoma reacted. The DTHR-T was specific in that all 77 healthy persons and 48/49 with other diseases, including 23/24 with non-cancer lung disease were negative; one patient with organizing interstitial pneumonitis was positive. This points to a possible source of false positive reactions. 91% of 149 patients with histologically benign breast disease had a negative DTHR-T; the histology of some of the positive ones was reexamined, 2 proved to have carcinoma in situ.

A ten-year experience (1970-1979) with 164 anterior mediastinotomies at a VA hospital to diagnose pulmonary or mediastinal lesions or to assess the resectability of carcinoma of the lung is reported. of 135 attempts to obtain diagnosis, 130 (96%) were successful. Of 19 patients who had a subsequent thoracotomy because the anterior mediastinotomy suggested that a curative resection was possible, 17 (90%) had successful resections. Two (1.7%) patients died-one of a paraneoplastic syndrome and one from progressive respiratory failure. Eleven complications in the 162 survivors included eight minor wound infections, an initially unrecognized pneumothorax, persistent bleeding from a lymph node biopsy site, and an air leak necessitating reoperation in another. Anterior mediastinotomy is a relatively safe procedure, even in patients with advanced carcinoma or lung disease. it has much less risks than a formal thoracotomy and provides much better exposure and diagnostic possibilities than a mediastinoscopy.

Two patients with small cell carcinoma of the lung treated by chemoradiotherapy developed, diffuse interstitial pneumonitis after 7 and 21 months of treatment while in complete remission of their malignant disease. One patient died after an acute respiratory distress syndrome, but the second improved after steroid therapy and discontinuation of cytotoxic therapy. Pulmonary toxicity appeared to be related to cyclophosphamide therapy, but radiation therapy could have potentiated cyclophosphamide toxicity as it has been shown in bleomycin lung disease.

The lung function of 30 consecutive patients with small cell carcinoma of the lung was evaluated before and 3 months after initiation of intensive chemotherapy. Radiological evaluation of the therapeutic effect on the lung tumor was possible in 19 patients after 3 months. Six patients achieved complete normalization of the chest X-ray, 10 patients achieved more than 50% reduction of the tumor and no or minimal changes in the radiological image were observed in 3 patients. Before treatment a mixed pattern of obstructive and restrictive lung disease was observed in all patients. In the 16 patients who achieved partial or complete remission of the tumor normalization of the total lung capacity (P less than 0.02), vital capacity (P less than 0.02), FEV1 (P less than 0.02) and PEF (P less than 0.05) was observed independently of the degree of shrinkage of the tumor on chest roentgenogram, thus suggesting that the tumor was the major cause of the lung function impairment in these patients. The diffusion capacity and parameters reflecting the function of the small airways (RV/TLC% and MEF50) remained abnormal after treatment. Improvement of the lung function did not predict the individual duration of survival. However, the study proved that roentgenological normalization is paralleled by physiological normalization with the current treatment of this disease.
