[Some epidemiological indicators in bronchopulmonary cancer in Sector 5 of Bucharest (study of 525 cases)]

The incidence was studied of broncho-pulmonary carcinoma, as well as of other epidemiological indicators in the 5th district of Bucharest over a period of 14 years (1960-1973) during which a total of 525 cases have occured. The incidence in this territory tends to become real from 1967 when the curve overtook the death-rate in the country. Following a continuous increase the number of cases reached 29 0/0000 in 1973 and it is presumed that it will attain 40 0/0000 in 1980. The increase in the morbidity is due to a higher number of cases noted in the extreme age groups (the increase was 2,5-fold in those under 40 years of age); the age group which was the most seriously involved was that between 60 and 69 years, in which the morbidity was of 111 0/0000. The proportion of women has also increased, from 1/6-th to 1/5-th of the total number of cases. In women the frequency of adenocarcinoma and of non-differentiated neoplasies is somewhat higher than in men. The proportion of histopathological confirmation of the disease diminished in the last years probably due to the higher number of aged subjects that cannot be correctly investigated or surgically treated.
