Carcinoid tumors of the lung.

Resection of typical bronchial carcinoid was carried out in 203 patients. The average age was 48 years, and the sex distribution was approximately equal. Bronchoscopy was the most definitive diagnostic procedure, even though 15% of the tumors were located in the segmental bronchus or beyond. Conservative resection including local removal of the lesion was the treatment of choice, but distal suppuration and location of the tumor necessitated pneumonectomy in 54 (27%) of the patients. The incidence of metastasis was 5% (11 patients), and the overall hospital mortality was 3%. Of patients who qualified for follow-up, 94% survived 5 years, and of those who were asymptomatic preoperatively, 98% survived 5 years. The 10- and 25-year survival rates for the group as a whole were 87 and 66%, respectively.

Palpation thyroiditis (multifocal granulomatour folliculitis).

Disseminated inflammatory lesions constituting a multifocal granulomatous folliculitis in the thyroid are described. These lesions were present in the majority (greater than 83%) of thyroids removed surgically because of thyroid or nonthyroid (carcinoma of the larynx) disease. They also were found at autopsy in patients who died while hospitalized but not in those who died at home. An identical lesion was produced experimentally in dogs by vigorously squeezing their thyroids. The human folliculitis is believed to result from traumatic injury or rupture of isolated thyroid follicles caused by palpation of the gland (palpation thyroiditis). Palpation thyroiditis may have little, if any, clinical importance. The remote possibility that it might be associated with iatrogenically produced metastasis of thyroid carcinoma is being investigated.

The Mayo Lung Project for early detection and localization of bronchogenic carcinoma: a status report.

The Mayo Lung Project (MLP) is a screening program designed to detect bronchogenic carcinoma at a curable stage. Screening tests include chest roentgenograms, three-day "pooled" sputum cytology studies, and lung-health questionnaires. These are being applied every four months to a study population of outpatients who have a high probability of developing lung cancer. Initial patient acceptance of the screening program has been excellent. Small asymptomatic lung cancers have been detected both roentgenographically and cytologically. The two procedures have complemented each other with little overlap. Chest roentgenography has proved most useful in diagnosing peripherally situated cancers, whereas sputum cytology studies have been most effective in identifying early squamous cancer involving major airways. At present, more cancers have been detected roentgenographically than cytologically, but the cytologically detected cases appear to have a better prognosis. Roentgenographically occult cancers have been localized with regularity, although the localization process is complicated. Theoretically, vigorous application of radiologic and cytologic screening, combined with optimum use of localizing procedures and treatment, could increase the five-year survival rate among lung cancer patients to nearly 50 percent. However, the actual survivorship attained will ultimately be determined by currently imponderable factors such as patient acceptance of longterm screening, frequency of multicentric respiratory cancers, and incidence of noncancerous smoking-related diseases, especially chronic obstructive pulmonary disease and ischemic heart disease.
