Lung carcinoma: survey of 2286 cases with emphasis on small cell type.

Lung carcinoma is the commonest major malignancy in men in the United States and its incidence is increasing rapidly in women. It is estimated that there will have been 117,000 new cases and 101,300 deaths in 1980. The 2286 patients with lung carcinoma admitted to the Hospital of the University of Mississippi from 1955 to 1980 were reviewed by decades of chronology and of life, with respect to age, cell type, sex and racial incidence. The greatest age incidence was in the sixth and seventh decades; cell types overall were epidermoid (45% of the patients), adenocarcinoma (12% of the patients), small (oat) cell (21% of the patients), and others (22% of the patients). There was a steady increase in the incidence of disease in females, adjusted for total hospital admissions, and a less certain increase among black patients. Twenty-eight per cent of 250 patients with small cell carcinoma so studied exhibited some feature of the paraneoplastic or paraendocrine syndromes. In 41 patients with small cell carcinoma treated with multiple drug chemotherapy, there was an overall response rate of 50% and an additional "stable disease" rate of 28%. Mean survival period in this group was 52 weeks, compared with 12 weeks in patients whose diseases went untreated. Clearly, definite progress is being made, not only in our knowledge of the biology of lung carcinoma, in general, but in the treatment of small cell carcinoma in particular.
