Risk factors of nonmelanoma skin cancer in Ragusa, Sicily: a case-control study.

A case-control study on 133 consecutive incident cases of nonmelanoma skin cancer registered by Cancer Registry of Ragusa (Sicily) was carried out in order to evaluate the correspondence between risk factors observed in other geographic areas with those of a Latin country with a strong solar exposure. A multivariate analysis showed that family history of skin cancer, cancer-related cutaneous diseases, fair skin color, residence more than 400 meters above sea level, and prolonged solar exposure without protection, significantly and independently increase the risk of skin cancer. Ease of suntanning was an important protective factor. Solar exposure was a stronger risk factor for squamous cell than for basal cell cancer. The results of the study enable us to identify a high risk group of people to whom simple methods of protection against solar exposure may be suggested to reduce the risk of skin cancer.

Comparison of cancer incidence among similar geographic areas: a better source of etiologic hypotheses?

Difference in incidence rates of cancer of specific sites among different populations has been a powerful tool for the generation of etiologic hypotheses. The use of strictly comparable data from cancer registries, on populations from Italy, France, Switzerland and Spain, similar for geographic location, race and ancestry, shows unexpected differences of rates of single cancer sites, being significantly higher or lower than those of the same subgroup of registries. The study of risk factors associated with such differences might be more profitable than those carried out on the basis of comparisons between distantly located populations.

Assessment of some risk factors for hepatocellular carcinoma: a case control study.

A case-control study of risk for hepatocellular carcinoma (HCC) was carried out in our Department from December 1980 to December 1983. One hundred and twenty consecutive inpatients with HCC were compared with 360 controls pair-matched by sex and age (within years). For each case three different controls were selected from inpatients at the same hospital: one patient with liver cirrhosis; one patient with solid tumor and one patient with chronic illness other than neoplasm or liver disease. We report here the results on alcohol consumption, smoking habit and hepatitis B virus infection. The risk factors investigated are distributed similarly in HCC and cirrhosis. The prevalence of alcohol abuse in HCC is similar to that in cirrhosis and is significantly higher than in other neoplastic or otherwise chronically ill patients (odds ratio 2 X 3 and 3 X 2 respectively). Thus alcohol abuse is probably a risk factor for HCC as a cause of cirrhosis. Smoking habits were similar among the various disease groups and independent of alcohol consumption. The prevalence of heavy smoking was comparable in cases and controls. HbsAg negative-HCC with an ultrasonographic pattern of 'diffuse' alteration was more frequent in heavy smokers.
