CLINICAL-DATA AND DESCRIPTIVE EPIDEMIOLOG Y OF LUNG-CARCINOMA OF THE PRIMARY TYPE

Systematical registration of morbidity for lung carcinoma of the prima ry type was performed since january 1979 for the departement of Isere, where a population of 940,000 inhabitants are living. Results for nin e sears registration (1979-1987) are dealing with 2,590 new cases. Cru de incidence for primary lung carcinoma is 55.7 per 100,000 among men, and 5.9 for women (sex ratio: 11.7). Upper lobe is the site more conc erned. There is no preference as regard laterality. When lymphatic nod es are explored (32%), there is an extension of the carcinoma for 75.2 % of them. At the moment of the diagnostic, there is already a metasta tis for 24% of the patients, mainly for bones. Among men and women, pr oportions for the squamous cell type are respectively 52.6% and 22.3% (60.8% and 28.7% of histologically identified cases), for the small ce ll type: 18.4% and 16.3% (21.2% and 21.0% of histologically identified cases), and for glandular carcinomas: 13.2% and 32.1% (11.9% and 41.5 % of histologically identified cases). Results of the pathological exa mination are known in 92.8% for primary lung carcinoma cases. As regar d first course treatment surgery is performed in 34.9% of the cases, r adiotherapy in 60.4%, and chemotherapy in 32.2%. Fairly high incidence of lung carcinoma in man in Isere, contrasts with rather low incidenc e in woman, a situation under different that the one in England and No rth America, where figures for women are slowly gaining over the one's for men.
