- Small bowel carcinoid tumor (SBC) is a rare disease of unknown etiology bill with all age-, sex-, and place-specific occurrence that may indicate an occupational origin. A European multicenter population-based case-control study was conducted from 1995 through 1997. Incident SBC cases between 35 and 69 years of age (n = 101) were identified, together with 3335 controls sampled from the catchment area of the cases. Histological review performed by a reference pathologist left 99 cases for study; 84 cases and 2070 population controls were interviewed. The industries most closely associated (a twofold or more odds ratio [OR]) with SBC taking into account a 10-year time lag after exposure were, among women, employment in wholesale industry of food and beverages (OR, 8.2; 95% confidence interval [CI], [1.9 to 34.9]) and among men, manufacture of motor vehicle bodies (OR, 5.2; 95% CI, 1.2 to 22.4), footwear (OR, 3.9: 95% CI, 0.9 to 16.1), and metal structures (OR, 3.3; 95% CI, 1.0 to 10.4). The identified high-risk occupations with all OR above 2 were shoemakers, structural metal preparers, construction painters and other construction workers. bookkeepers, machine fitters, and welders (men). The OR for regular occupational use of organic. solvents for at least half a year was 2.0 (95% CI, 1.0 to 4.2). Exposure to rust-preventive paint containing lead was suggested as another potential occupational exposure (OR, 9.1; 95% CI, 0.8 to 107). This explorative study suggests an association between certain occupational exposures and SBC, bill some of these associations could be attributable to chance. All findings should be regarded as tentative.

- Objective: Little is known about the etiology of small bowel carcinoid tumor (SBC), but a few studies have pointed to certain medical and lifestyle factors as potential risk factors. This study aims to evaluate these findings and to identify new associations. Methods: A population-based European multicenter case-control study was conducted from 1995 through 1997. Incident histologically verified 35-69 year-old SBC cases (n = 99) and 3335 controls were recruited; 84 cases and 2070 controls were interviewed. Results: Ever being a smoker was associated with SBC (odds ratio = 1.9; 95% confidence interval 1.1-3.2) and increased risk estimates were seen for all smoking categories. SBC was associated with previous gallstone disease and ovariectomy, but only when these conditions occurred within two years prior to the SBC diagnosis. No association was seen for a history of cholecystitis, liver cirrhosis, ulcerative disease, or Crohn's disease. Intake of alcoholic beverages - as well as medical treatments with radioactive substances, hormones, or corticosteroid tablets - were not associated with SBC. Conclusions: This study indicates that tobacco smoking is a risk factor for SBC. The associations with gallstone and ovarian diseases may be due to enhanced medical surveillance during the early phase of the cancer disease.
