Lung Cancer | Year: 2013

The incidence of lung cancer has dramatically increased in ten years, being now the most commonly diagnosed cancer in males and the fourth most commonly diagnosed cancer in females. Considering social and scientific evolution, the aim of the present study conducted by the French College of General Hospital Respiratory Physicians (CPHG) was to compare patient and lung cancer characteristics at a ten-year interval. Two epidemiological studies, KBP-2000-CPHG and KBP-2010-CPHG, were conducted at a ten-year interval. These prospective multicentre studies included all patients ≥18 years of age with primary lung cancer diagnosed between 1st January and 31st December 2000 or 2010, and managed in the respiratory departments of one of the participating general hospitals. A standardised form was completed for each patient. A steering committee checked recruitment exhaustiveness. Respectively, in 2000 and 2010, 137 and 104 centres included 5667 and 7051 patients. Compared to 2000, patients in 2010 were significantly older (65.5. ± 11.3 vs. 64.3. ± 11.5 years, p< 0.0001), more frequently women (24.3% vs. 16.0%, p< 0.0001) and never-smokers (10.9% vs. 7.2%, p< 0.0001). In 2010, adenocarcinoma was the most common tumour (45.4%, vs. 29.0% in 2000, p< 0.0001). The adenocarcinoma rate increased irrespective of sex, age, or smoking status (relative risk [RR] before and after adjustment, RR = 2.07 [1.92-2.24], p< 0.0001 and 2.06 [1.90-2.23], p< 0.0001). In ten years, lung cancer characteristics have therefore changed: more women, more never-smokers, and more adenocarcinomas. The particular high increase in adenocarcinoma rate deserves further analysis. © 2013 Elsevier Ireland Ltd.
