ABSTRACT
BACKGROUND:
The Faroe Islands are a group of small islands in the north Atlantic. The population is well-defined and is therefore very suitable for epidemiological research, including dietary studies in relation to carcinogenesis. With the establishment of a cancer registry on January 1, 1994, with data from 1960, inspection of incidence rates and trends in cancer may give clues to areas for etiologic research.METHODS:
We identified retrospectively all incident cases of colorectal cancer in the period 1979-1993, by reviewing all case reports and death certificates in the Faroe Islands.RESULTS:
We found 242 cases of colorectal cancer 166 colon cancers and 76 rectal cancer, of which 93% and 96% (respectively) were histologically confirmed. Colorectal cancer incidence was significantly lower than in Denmark, with standardised incidence ratios (SIRs) for colon cancer at 0.8 (95% CI = 0.7-1.0) in men and 0.7 (95% CI = 0.6-0.9) in women. For rectal cancer SIRs were 0.6 (95% CI = 0.5-0.9) in males and 0.6 (95% CI = 0.4-0.9) in females.CONCLUSIONS:
This paper presents for the first time incidence rates of colorectal cancer in the Faroe Islands. For both cancer types the most recent standardised incidence rates, 1989-1993, were among the lowest in north western Europe and North America. This relatively low risk of colorectal cancer occurs in spite of a low intake of vegetables and a high intake of total fat. However, the Faroese diet is high in fish, calcium and vitamin D and the possibility therefore exist that the low rates are due to a protective effect of these nutrients and micronutrients.
