Smoking, occupational risk factors, and bronchial tumor location: a possible impact for lung cancer computed tomography scan screening.

Introduction: The aim of this study was to describe associations between lung tumor location and smoking as well as selected occupational exposures. In the context of lung cancer screening by computed tomography scan, tumor location may have an interest. Computed tomography scan is known to better detect more peripheral tumors.

Characteristics of never smoker lung cancer including environmental and occupational risk factors.

Introduction: Clinical characteristics and risk factors of nonsmoker patients with lung cancer are still debated.

Aim And Methods: The aim of this work is to describe the characteristics of never smoker patients with lung cancer, focusing on occupational and environmental exposures, Data collected were: age, gender, histological types, methods of diagnosis, TNM staging, smoking, and occupational data. Statistical analysis included descriptive analyses, Pearson's chi-square or nonparametric tests, and logistic regressions.

[Lung cancer and occupational exposures (asbestos not considered)].

Lung cancer is associated to numerous occupational exposures, apart from asbestos. Today, the most frequent products observed in France were polycyclic aromatics hydrocarbons, silica, diesel exhaust, radon and some metal salts as chromium, nickel, cadmium, and beryllium. The main occupational exposures were described and tools for the screening of these exposures were proposed.
