SEOM guidelines for the management of non-small-cell lung cancer (NSCLC).

Lung cancer is currently the most common malignancy and also the leading cause of mortality related to cancer in the world [1]. The crude incidence of lung cancer in the EU is 52.5/100,000/year, while the mortality 48.7/100,000/year. Among men the rates are 82.5 and 77.0/100,000/year, and among women 23.9 and 22.3/100,000/year, respectively. Non-small-cell lung cancer (NSCLC) accounts for 80% of all cases. In Spain, there were 16,879 deaths in men, with a mean age of 68 years, and 2634 deaths in women, with a mean age of 66 years. The incidence of lung cancer in Spain was 68.3/100,000 among men and 13.8/100,000 among women, according to the latest data published in the year 2006 by the Instituto Nacional de Estadística. About 90% of lung cancer mortality among men (and 80% among women) is attributable to smoking.
