[Epidemiologic study of laryngeal cancer in Yugoslavia].

In Yugoslavia cancer of the larynx has an important position in the group of malignant tumours, especially among the malignomas of the respiratory system. According to the data on mortality, laryngeal cancer accounts for 2.67% of all tumours and 11.59% of all respiratory tract tumours during the period from 1977 to 1988. In that period the average age-adjusted mortality rate of laryngeal cancer was 3.09 per 100,000 population, much higher in mean--6.29%(000) than the women--0.53%(000). The linear trend in laryngeal cancer mortality from 1977 to 1988 points to a slight increase (y = 2.97 +/- 0.02x), in men (y = 6.03 +/- 0.04x), while in women it shows a decrease (y = 0.60--0.01x). Age specific mortality rates of laryngeal cancer are low in the age groups to 39 years in men and 49 years in women. It augments steadily from 40 and 50 years of age respectively, with the highest rates in patients above 70 years of age (39.66%(000) for men and 4.05%(000) for women).
