A case-control study on colon cancer was conducted encompassing 329 cases and 658 controls. Occupations and various exposures were assessed by questionnaires. A decreased risk was found in persons with physically active occupations. This effect was most pronounced in colon descendens and sigmoideum

β¦ Synopsis
The association between nasal cancer and various occupations was investigated in a case-control study in the provinces of Verona and Vicenza (northeastern Italy) and Siena (central Italy). Cases of malignant epithelial neoplasm of the nasal cavities and paranasal sinuses diagnosed in the years 1982-1987 in the hospitals of Verona, Legnago, Bussolengo, Vicenza, and Siena comprised the study. Controls were patients admitted to the same hospitals as the cases, with any diagnosis except chronic rhino-sinusal disease and nasal bleeding. Age, gender, residency, and date of admission were taken into account by matching. Cases and controls, or their next of kin, were interviewed or required to fill in a mailed questionnaire; the overall response rate was 70%. Altogether, 78 cases and 254 controls provided information on occupational history. Significantly increased risks were associated (in males) with work in the wood industry (odds ratio [O.R.] : 5.8; 90% confidence interval [C.I.] : (2.2-16) and in the leather industry (6.8; 1.9-25). Textile workers, furnacemen, construction workers, and workers with possible exposure to organic dusts showed increased risks even if statistical significance was not reached.
