| Abstract | tIntroduction: Apart from the association with tobacco consumption, other factors of importance for pre-vention and early diagnosis of lung cancer have received little attention. We present a case%control studyfocusing on professional exposure to carcinogens and social status. Methods: A written questionnaire was completed by 551 consecutive patients with lung cancer and 494patients with large bowel cancer. The groups were balanced regarding gender and age distribution. Thequestionnaire included data on place of birth, education, smoking history, diet and alcohol intake, bodyweight and height, occupation, housing conditions and family income. According to standard epidemi-ological criteria, professional exposure to carcinogens was classified as professions with exposure toconfirmed lung cancer carcinogens, professions with exposure to suspected lung cancer carcinogens andother professions. Results: As expected, there were significant differences between the two groups regarding smoking status. While there were no significant differences in educational levels, more immigrants were among patientswith lung cancer (17.9% vs 11.6%, p = 0.005). On average, lung cancer patients had a lower body massindex (BMI) at 24.77, as compared to 26.14 for large bowel cancer (p = 0.000). Lung cancer patients hadlower income and poorer housing conditions; the bivariate difference was significant both for incomelevels (p = 0.046) and type of residence (p = 0.009). The proportion of patients working in professions withexposures to known carcinogens was 33.5% for lung cancer, and 17.1% for large bowel cancer (p = 0.000).In the multivariate analysis, smoking (p = 0.000), BMI (p = 0.000) and type of occupation (p = 0.001) weresignificant factors. Conclusions: While there is no doubt about smoking in lung cancer carcinogenesis, professional exposureto carcinogens and belonging to lower socio-economic strata also play an important role. | |
