title: [Trends in mortality from respiratory tract tumors in Italy, 1969-1987].
abstract: Trends of Italian death certification for cancers of the lung, larynx, pleura and nasal sinuses were analyzed for both sexes in the period from 1969 to 1987. For lung and laryngeal cancer, the analyses have been conducted for broad geographical areas within Italy (North, Center and South). Mortality rates for males aged 35-44 years consistently decreased in the North; increased until the late 1970's, and then decreased in the Center; and consistently increased in the South. In the 45-54 age group, mortality rates peaked in all areas between the late 1970's and the early 1980's, subsequently decreasing. For ages over 54 years, the rates continued to increase even in the 1980's. Female lung cancer rates increased in all areas and in all age groups over 35 years. In the 25-34 years old age group the rates decreased in the North and tended to increase in the Center and in the South. Below age 50, the increases were proportional in the three areas, while for older ages the increase was greater in the North both in absolute and proportional terms. Cohort effects showed a general increase for the generations born up to 1930, in both sexes and in all geographical areas. Different trends were observed for cohorts born after 1940: decreasing for both sexes in the North, and steady for men and increasing for women in the other areas. From the mid 1970's, laryngeal cancer standardized rates for 35-64 age group decreased, or at most remained constant, in all geographical areas. The decreasing tendency was more marked in men. Larynx cancer cohort effects for men were at a maximum for cohorts born around 1990, decreasing thereafter. In women, cohort effects appeared to consistently decrease. Overall rates of pleural cancer mortality increased during the period 1969-1987, and the sex ratio was stable, from 1980 onwards, at a value of about 2.4. Cohort effects showed, for pleural cancer, a general increase for all the cohorts. The increase was particularly apparent in male cohorts born after 1930. Overall mortality rates for cancer of the nasal sinuses was rather stable in both sexes from 1975 onwards. However, in the 35-64 year age group, mortality rates increase for males and decreased for females.
