Descriptive epidemiology of small intestinal malignancies: The German Cancer Registry Experience

Abstract

In the first population-based analysis of certain epidemiologic features of primary malignancies of the small intestine in Germany, we used data from the Saarland Cancer Registry (1982-1993) and from the former National Cancer Registry of the German Democratic Republic (1976-1989). The age-standardized incidence rates for ages 0-74 years is 3.3-6.2 per million per year. The average incidence rates of the federal state Saarland are for men about 1.3 times and for women about 1.4 times the rate of the former German Democratic Republic. After the age of 30 years, the incidence rates increased with increasing age. Incidence rates for carcinoids levelled off after the age of 54 years. Rates for men were 35-40% higher than for women after adjusting for age. The risk for carcinomas, malignant carcinoids and malignant lymphoma were higher for men than for women.
