A case-control study of lung cancer in Polish women.
This study was undertaken to examine the influence of active and passive smoking, cancer family history, occupational exposure, usual diet and alcohol consumption on female lung cancer risk. A total of 242 women with histologically confirmed primary lung cancer and 352 healthy controls were involved in the study. All subjects were interviewed in the hospital. Data were analysed using multivariate logistic regression. Multivariate analysis has shown that smoking was the most strongly active risk factor in female lung cancer. Positive dose-response relationship was observed between lung cancer risk and number of pack-years. Passive smoking exposure during childhood significantly increased the risk (OR=2.65). There was also observed a significantly increased risk of lung cancer among women who had siblings with history of cancer (OR=3.42). Occupational exposure to coal dust, acid fumes (sulphuric and/or hydrochloric) and materials used for rubber making significantly increased the risk. Frequent intake of carrots (at least five times a week) and also daily intake of other vegetables significantly lowered the risk (OR=0.13, OR=0.24). A significant protective effect was also observed in women frequently using margarine on bread (OR=0.14). Vodka drinkers showed significantly higher risk than non-drinking women. The analysis of dose-response relationship in reference to vodka drinking also confirmed significant influence of this factor on the risk.
