Three thousand patients with primary carcinoma of the lung entered in the Armed Forces Central Medical Registry are reported. Forty-one per cent had squamous cell, 28.5 per cent adenocarcinoma, 25.2 per cent small cell/undifferentiated, and 4.9 per cent miscellaneous cell types. When first seen, 71.1 per cent had no organ metastases and 50.6 per cent no lymph node metastases. Over-all survival rate was 18.2 per cent at 5 years and 14.5 per cent at 10 years. Survival following definitive resection, palliative resection, definitive radiation, palliative radiation, and chemotherapy was determined both in the presence of mediastinal nodal involvement and in the absence of mediatinal nodal involvement. Where resection for cure could be carried out, 5 year survival rates of 48.8 per cent were possible. The factors affecting this improved outlook in our military population are discussed and, in general, appear to be related to a ready accessibility of medical care and the necessity, because of global commitments, of establishing an early diagnosis. Cell type ecerted some influence on survival, but the major determinant appeared to be the absence of involved nodes at the time of the operation.

Surgical resection has failed notably as definitive treatment for small cell carcinoma of the lung. Newer treatment programs combining intensive chemotherapy with radiation therapy achieve a significant response in about 85 percent of cases, with about 50 percent of patients showing clinically complete remission. Long-term survival without recurrence has been the outcome in a small minority of cases. A frequent mode of failure after treatment of limited disease is recurrence within the chest. The course of one patient treated early in this series suggests that exclusion of initial surgical resection from programs of combined treatment may be a serious omission. Since that time, four patients have undergone initial resection, apparently with uniformly favorable courses to date. Selection criteria based on staging factors are proposed. Admittedly, only a minority of patients will be suitable for this treatment at the time of first diagnosis. Much opportunity exists for improvement in survival rates of patients, even those with limited disease.

In 92 consecutive pulmonary needle biopsies, preliminary diagnoses on the basis of radiological and clinical data were compared with cytological reports. Three groups emerged. In the first, of 43 cases with radiological changes typical for primary lung carcinoma and no clinical data making other diagnosis a plausible alternative, the cytologist found carcinoma cells in 37 and malignant lymphoma cells in one. A further 3 cases proved to be carcinomas at the histological examination. Two cases were not carcinomas. In the second group, where 30 patients displayed radiological changes less typical for primary diagnoses, or clinical/anamnestical data also supported alternative diagnoses, the cytologist found malignancies in 8 cases, carcinoid in one and no signs of malignancy in 21 cases. In 19 cases the patients were considered radiologically to have no malignancies. Malignant cells were found in none. It is concluded that in a certain group of patients, the diagnosis of pulmonary carcinoma can be made with reasonable accuracy from radiological and clinical data alone. Needle aspiration biopsy and similar techniques are of questionable value as routine procedures when the probability of this diagnosis is already very high on other grounds. Their use should be reserved for cases where plausible diagnostic alternatives are present.

Fewer than 40 cases of giant-cell carcinoma of the lung have been described in the world literature. Fourteen new cases are now presented. This is a special type of large-cell anaplastic carcinoma characterized by tumour giant cells with one or more nuclei and by a very pleomorphic appearance. A number of previous authors have emphasized the following special features of this type of tumour. Occurrence in a younger age group, a more rapid course from initial symptoms until death, more extensive metastasization, and a more peripheral location of the primary tumour than in other large-cell anaplastic carcinomas. It has also been stated that the tumour differs from other large-cell anaplastic carcinomas in its shorter duration (average 4 1/2 months) and more peripheral distribution (c/p ratio 1:2.2). In the present material only the survival period was significantly shorter (average 7 months), while in other respects the tumour did not differ from other large-cell anaplastic carcinomas.

Sixty patients underwent flexible fiberoptic bronchoscopy and percutaneous needle aspiration of peripheral lung lesions with fluoroscopic monitoring. A single general anesthetic was used. We found that percutaneous needle aspiration was the more accurate of the two procedures in establishing a diagnosis but that flexible fiberoptic bronchoscopy proved complementary in some instances. The incidence of pneumothorax was 27% but aspiration was needed in only 8%. There were no other complications. In 84% of patients with primary carcinoma of the lung presenting as a peripheral lesion, the diagnosis was established by these procedures. The accuracy was less in metastatic lesions and considerably less in benign lesions.

Experience at the Massachusetts General Hospital (MGH) with resections for primary lung carcinoma is brought up to the clinical staging era (1971) with a 5 year cumulative survival statistic of 30 percent for the period 1964 through 1970. Comparison of four decades of experience reveals no change in cumulative survival for pulmomary resections for primary lung carcinoma in the years 1941 through 1970. Attention is directed to the hospital mortality rates for pneumonectomy and lobectomy and to the principal causes for these rates. Lymph node metastasis continues to be the single most ominous predictor of potential survival after pulmonary resection for carcinoma, particularly for all non-squamous cell types.

Levamisole, a potentiator of cell-mediated immunity, has been reported to increase survival in patients with resectable carcinoma of the lung. Cell-mediated immunity can be measured in vitro by the leukocyte migration inhibition test. We have previously reported that this test detects cell-mediated immunity to human lung tumor antigens. In the present studies, patients with lung cancer were treated with Levamisole. Their leukocytes were evaluated in the leukocyte migration inhibition assay before, during, and following Levamisole therapy. Small increases in cell-mediated immunity were observed when patients had a high pre-existing tumor immunity. When tumor-associated reactivity was absent prior to therapy, larger increases were measured. Although Levamisole is a nonspecific immunostimulant, these data indicate that in vitro anti-tumor immune responses are enhanced by Levamisole therapy. Augmentation of cell-mediated immunity to tumor antigens may explain the clinical benefits of Levamisole therapy.

This paper reviews the problem of radiation-induced carcinoma of the lung in the fluorspar mines of Newfoundland. Seventy-eight workers have died from this disease since commercial operation commenced in 1933. In 1959 the source of the radiation was identified as radon, and its daughter nucleotides present as contaminants in water seeping into the mines. Heavy smoking is probably a synergistic cocarcinogen. The histology in this group of patients with radiation-induced lung cancers is unusual, since squamous cell carcinoma accounts for 90 percent of all cases. There have been four patients with second primary lung cancers. Radical radiotherapy has been the primary mode of treatment based on the reluctance of the miners to undergo operation. Surprisingly good results have been obtained, with an average survival time of 34 months after treatment. Institution of improved ventilation has reduced radiation to safe levels, but an estimated 120 miners from the pre-1960 era are still at risk.

This study follows the clinical course of 22 patients in the active phase of infective endocarditis who inderwent valve replacement at North Carolina Memorial Hospital between March, 1966, and March, 1976. At the time of operation, there was gross valve tissue destruction in 16 patients, verrucae in nine, ruptured chordae tendineae in five, and myocardial or annular abscess formation in five. Four patients survived less than 6 months after the initial operation. One survived almost 3 years before dying of recurrent carcinoma of the lung. The remaining 17 patients have been followed an average of 4.6 years. Major postoperative complications were as follows: paravalvular problem, five patients; congestive heart failure, seven patients; complete heart block, three patients; systemic arterial emboli, four patients. These complications often were associated with the preoperative presence of annular or myocardial abscess. Thus it appears that postoperative complications often result from annular structural deficiencies rather than being directly related to active infection.

Gallium-67 citrate scanning was prospectively evaluated in 55 patients who had lung lesions suspected to be primary carcinoma on chest x-ray films and in whom subsequent histologic diagnosis was obtained. Of 47 patients with histologically proved carcinoma of the lung, 44 (94 per cent) had a positive 67Ga scan. No patient with a positive scan had a benign lesion, so that the positive scan accuracy rate was 100 per cent. All 8 patients with a benign lesion and 3 patients with a malignant lesion had negative scans, for a negative scan accurary rate of 72 per cent for benign lesions. These results give statistical validity for the usefulness of the 67Ga scan in diagnosing carcinoma of the lung (p less than 0.001). Tumor cell type had little effect on the sensitivity of 67Ga scan. The 67Ga scan was equally useful in the evaluation of peripheral and central lesions. There was little difference amount T1, T2, and T3 classified lesions in their ability to take up 67Ga. The 67Ga scan was competitive with mediastinoscopy in assessing mediastinal lymph node metastases and provides a noninvasive method of assessing hilar lymph node metastases. There was a good correlation between the clinical staging of patients with lung cancer based on a chest x-ray film and 67Ga scanning and the staging after surgical treatment based on the histology of the resected specimens.
