Mortality rates of cancer of the larynx in the town of Torino, in the whole of Italy and in France during 1950–71 are reported. Age standardized mortality rates as well as mortality rates truncated to the period 35–64 years of age are reported in Table 1 for males and in Table 2 for females. Graph 1 represents age specific mortality rates for cancer of the larynx in the three areas in 1966–67. Graphs 2, 3 and 4 report mortality rates in males in the three ares for cohort of birth. All rates are annual/100.000. An increase of mortality for cancer of the larynx in men is well documented in the town of Torino. From 1951 to 1966 the mortality rate truncated to age 35–64 increased from 6.3 to 12.0. The proportion of mortality for cancer of the larynx/mortality for all cancers during the same period increased from 3.1 % to 5.4%. In Italy, the mortality rate in men aged 35–64 was 6.5 in 1952 and 9.3 in 1967: during the same period the proportion of mortality for cancer of the larynx/mortality for all cancers increased from 3.8 % to 4.4 %. In France, the tendency to an increase of mortality for laryngeal cancer after 1951 was absent or debatable, although both the mortality rates of cancer of the larynx and the proportion of mortality for cancer of the larynx/mortality for all cancers were consistently higher than in Italy or in Torino. However, in 1966–67 at ages 35–44 the mortality rate for cancer of the larynx in men was higher in Torino than in France (Graph 1).
