RESUMO

LIFE system (lung imaging fluorescence endoscope) is a new system of detection for early lung cancer using a He-Cd laser through a conventional fiberoptic bronchoscope. This system is able to capture and processing the autofluorescence from the bronchial mucosa and to show it in a video screen in real time. In the screen the normal tissue appears in green colour and the neoplastic tissue in brown colour. The first studies performed with LIFE system show the same specificity of the conventional bronchoscopy but the sensibility is 50% higher. In this paper we present the first case of detection of a occult squamous cell carcinoma with sputum and bronchial aspiration cytology positive for carcinoma but chest X ray, CT scanner and bronchoscopy negative for lung cancer. The LIFE system was able to detect carcinoma in the carina.

RESUMO

A case-control study on women was carried out in Barcelona, Spain, to investigate the relationship of lung cancer with the intake of vegetables, fruits and some foods of animal origin. The study included 103 cases and 206 controls matched by age and residence. Diet intake was assessed by means of a food frequency questionnaire. A reduction in risk, adjusted for smoking habit, was found for the intake of yellow/orange vegetables (mainly carrots) and tomatoes. The odds ratio (OR) and 95% confidence interval (CI) for the highest versus lowest tertile of intake were 0.37 (0.19-0.74) for yellow/orange vegetables and 0.45 (0.22-0.91) for tomatoes; both had a significant inverse trend. A tendency to a reduction in risk of lung cancer with increased intake was observed for all vegetables, leafy green vegetables, dark green vegetables and cruciferous, but these associations did not reach statistical significance. No association with lung cancer was found for the intake of fruits or foods of animal origin rich in retinol. Similar patterns were observed for women who never smoked and when the analysis was restricted to adenocarcinoma.
