Descriptive epidemiology of Hodgkin's disease in the province of Torino, 1965-71.
Age-standardized incidence rates of Hodgkin's disease in the province of Torino in 1965-1971 were 2.81/100,000/year in males and 1.64 in females, i.e., somewhat lower than in urban areas of other industrialized countries. In the whole province, age-distribution for males was similar to previous findings elsewhere, with a young-adult peak at ages 25-34. However, in the city of Torino, males showed a first peak in the age-class 35-44, while in the rest of the province an infantile peak (0-14 years) was found. By dividing the latter area in suburbs and nonmetropolitan area, the infantile peak was confirmed only in the nonmetropolitan area. Females showed a different behavior: in the city of Torino there was a unimodal curve (peak in age-class 55-64), and in the rest of the province there was a bimodal curve with a first peak in age-class 15-24. These patterns have been analyzed in relation to the suggestion of a distribution by age of Hodgkin's disease following 3 types (nonindustrialized countries, urban areas of industrialized countries and rural areas of industrialized countries). No significant differences in the distribution of cases were found among the smallest geographical units considered (ULSs), in contrast with previous findings on cancer of the larynx and bladder, which showed marked geographical differences within the province of Torino.
