title: [Epidemiological study of lung cancer in Portugal (2000/2002)].
abstract: Lung cancer is the most common form of cancer death in the world. Five-year survival is about 15%, without any change to this picture envisaged. It is the 3rd most prevalent type of cancer in Portugal and the primary cause of cancer death. 85% of lung cancer cases are attributable to smoking. One study performed in Portugal for 3 years (2000/2002) by the Lung Oncology Work Committee of the Portuguese Society of Pulmonology in 22 Hospitals showed that of a total of 4396 patients with lung cancer, 81.8% were male and 18.2% were female, with a mean age of 64.49 +/- 11.28 years. About 70% of patients were smokers or former smokers, with 50.3% of patients presenting with performance status (Zubrod) 1. Histologically, 37.5% were adenocarcinoma, followed by squamous carcinoma in 30.5% of cases, and small cell lung cancer in 12.5%; neuroendocrine carcinoma presented in 1.4% of cases; non small cell lung cancer in 10.5%; mixed carcinoma in 0.7%; large cell carcinoma in 2.3%; and others/not specified in 4.6% of cases. Staging (known in 4097 patients), showed 113 patients in stage IA (2.8%)and 250 patients in stage IB (6.1%); only 0.8% in stage IIA and 4.5% in stage IIB; 9.1% in stage IIIA and 29.9% in stage IIIB; 46.9% were already in stage IV by the time of diagnosis. The first therapeutic option was known in 3855 patients. Surgery was performed in 8.2% and 21.8% of cases were treated with combined therapies (surgery and chemotherapy or radiotherapy, or combination of chemotherapy and radiotherapy); chemotherapy alone was first choice in 43.7% of patients and in 20.3% only best support therapy was chosen.
