A unique case-control study design including family members of cases and controls was used to assess the association between serum beta-carotene and cancer.
The cases (n=389) were incident cancer cases diagnosed between 1981 and 1984 in Wellington, New Zealand, and the controls (n=391) were hospital patients without cancer.
Low levels of beta-carotene were observed for individuals with a number of cancers, including cancers of the lung, stomach, esophagus, small intestine, cervix, and uterus.
Low levels of beta-carotene were also found in the relatives of these cancer patients.
These differences persisted after stratification by current cigarette smoking.
