A comparative study of the inhibitory effect of cell-free supernatants (CFS) from human lung cancer cell lines (ChaGo and PC-1) and from a human embryo fibroblast cell line on lymphocyte blastogenesis indicated that both lung cancer cell lines produce a large amount of the inhibitory factor while the production of such a factor from a control noncancer cell line is essentially very minimal or absent. The inhibitory effect of CFS of the lung cancer cell lines is not due to direct cytotoxicity. The inhibitory effect is found to be partially sensitive to heat treatment. A significant inhibition is still seen, even when the CFS of the lung cancer cell lines were present for 1 hour prior to the addition of phytohemagglutinin (PHA).

Lung cancer morbidity in MSSR is analysed on the basis of statistical data for 1966-1972. The rate of lung cancer incidence is found to be higher than in cancer of the stomach. As a result of extrapolation of average tendencies in the morbidity and mortality of main cancer localizations, it was found that provided the observed tendencies are remained, lung cancer will occupy the first place in the structure of oncological morbidity (to 1976--1977) and mortality (to 1979--1980).

An associated simultaneous mediastino- and laparoscopy allows the detection of lung cancer metastases in lymph nodes of the anterior mediastinum and liver and thereby the precise determination of the tumor process stage. The procedure is tolerated by patients well. 100 examinations showed metastases in mediastinal lymph nodes in 27 cases, in the liver- in 7. No complications were noted. Metastases were most frequently found in patients with undifferentiated lung cancer. Hepatic scanning by means of radioactive gold was performed in 30 patients. Laparoscopic data correlated well with scannographic findings.

Evidence accumulated since 1964 appears to show that occupation, not cigarette smoking, may be the primary cause of lung disease, especially of cancer and chronic obstructive disease. Comparisons of groups of individuals who smoke more with those who smoke less actually serve to contrast groups with a high proportion of blue-collar workers exposed to toxic fumes and a low proportion of professionals, managers, and proprietors with groups having lower proportions of blue-collar workers and higher proportions of professionals, managers, and proprietors. Thus, many diseases associated with smoking actually may be of occupational origin. Indeed, more than a dozen recent investigations of lung cancer epidemics among industrial workers have failed to find smoking to be a major cause (in some, not even a contributing cause). This evidence is strengthened further by shifts in the incidence of lung cancer that follow in time shifts in industrial employment patterns. Yet a worker's past smoking habits seem to play a key role in decreasing compensation awards for injuries that actually may be due to occupational exposure rather than personal habits. Thus, the relationship between smoking, occupation, and disease needs serious clarification. Smoking appears to have been used to divert attention away from the effects of occupational and environmental exposures to toxic substances.

Twenty one patients with lung cancer and twelve patients with unspecified lung disease were evaluated by means of delayed cutaneous hypersensitivity skin tests with tumour associated antigen. Nine of these patients with lung cancer and seven healthy persons were evaluated by in vitro assays of lymphocyte function to tumour associated antigen (TAA) from "Cancerotest Dessau". We did not find a statistically significant lymphocyte transformation to the testing concentration of TAA. For the same patients with lung cancer and controls we found statistically significant results of the mean lymphocyte transformation to phytohemagglutinin. It has been shown that the delayed cutaneous hypersensitivity skin tests demonstrated "false positive" reactions to TAA. It is possible that this is an expression of the irritative effects of TAA. It is estimated that the application of the antigens in this form presented and in this chosen examination conditions, does not allow for definite diagnostic assessment to be expected.

A method for determining the incidence of malignancies of the stomach, colon, rectum, and lungs has been based on the frequency of the tumors in the autopsy material of the Institute of Pathology of the University of Heidelberg for the period 1900 to 1975. The main goal of this model is time independent selection of autopsy material indicated by an almost constant pattern for sex, average age at death, number of inhabitants, and number of autopsies. There is a relationship between incidence and autopsy frequency only when coding the diagnoses independently of their contributions to the cause of death. The results show a nearly constant incidence of stomach cancer, a steady incidence of colon and rectal cancer which, however, differs for men and women, and a large increase in the incidence of lung cancer.

Chlorozotocin was given to 37 patients with advanced malignant tumors in a daily X 5 schedule at 6-week intervals. Total iv doses for each course ranged from 75 to 200 mg/m2. Myelosuppression was dose-limiting, with a platelet count depression regularly observed at doses of greater or equal to 150 mg/m2; leukopenia occurred only at the highest dose level. Nausea and vomiting were mild and uncommon. No hyperglycemia or adverse drug-related effects on renal or hepatic function were observed. No major antitumor activity occurred; however, three patients with renal cell carcinoma and one patient each with lung cancer, ovarian carcinoma, and Hodgkin's disease had minor objective decreases in tumor size. A dose range of 150--200 mg/m2 iv for each 5-day course is recommended for phase II studies.

The solid phase Clq radioimmunoassay was used to detect immune complexes in sera from patients with systemic lupus erythematosus (14/25), rheumatoid arthritis (4/5), vasculitis (5/15), infective endocarditis (2/2), acute rheumatic fever (2/3), pre-eclamptic toxaemia (0/14), lung cancer (3/7), glomerulonephritis (26/98) and renal transplant patients (0/5). The best correlation with disease activity was seen in systemic lupus erythematosus and infective endocarditis where serial immune complex determinations were clearly of value in monitoring therapy. The findings in primary glomerulonephritis indicate only a limited usefulness of the assay in that serum immune complexes were detected in a minority (22/73) of patients with glomerular immune deposits. In particular the data do not support a role for Clq fixing immune complexes in the pathogenesis of membranous glomerulonephritis or in pre-eclamptic toxaemia.

Usnic acid, a lichen antibiotic, showed low-level activity in the Lewis lung carcinoma test system. In an effort to produce new agents of potential use in the treatment of lung cancer, derivatives of the natural product were synthesized and evaluated with a cytotoxicity assay. Structure--activity analysis of the cytotoxicity data indicated the importance of the lipophilicity and the beta-triketone moiety of usnic acid on cytotoxicity. No significant increases in survival of test animals over controls were shown by any of the synthetic compounds in the P388 leukemia or the Lewis lung carcinoma test systems.

The spread pattern was studied in 48 autopsied cases of irradiated, apparently localized lung cancer. Disease was found in the upper abdomen in 52%, in the brain in 8.7%; in the bones in 20.8%; and confined to the thoracic cavity in 27%. Radical irradiation controlled 38% locally. The pattern of metastasis in these irradiated lung tumors did not seem to differ from that of unirradiated lung cancers reported elsewhere.
