INTRODUCTION. Lung cancer is the most frequent cause of death formalignant tumor. In our country lung cancer is the third cause of death by cancer in 2009. The main risk factor for developing lung cancer is still smoking, and adenocarcinoma is the most frequent histological type. 23 % of those cancers are diagnosed by early stage.
MATERIALS AND METHODS. Descriptive study was done in patients who were diagnosed for lung cancer.We evaluate demographic variables, smoking, histological type, anatomy of the lesion and clinical stage. Database and analysis were done with Epi Info version 3.5.2.
RESULTS. We have documented 20 cases, where the main age was 65 years old; they were associated for smoking in the 65 % of the cases. 95 % of lung tumor corresponded to non-small cell cancer. We did not find any difference between central o peripheral localization (p 0.1). We did not find any difference between smoking and histological type (p 0.8), no difference were found between histological type and anatomical site of the lesion. We only found 5 % of lung cancer in early stage I and II.
DISCUSSION. The majority of patients with lung cancer were older than 50 years of age with cigarette exposure; however, we found 30-year old patients suffering from lung cancer without any tobacco exposure. In that case we have to consider other factors. Finally we only found 5% of lung cancer in early stages (I and II), by far lesser than described in to the world medical literature around 23%. There are important limitations for a good early diagnosis; currently we recommend low-dosage chest computerized tomography; however, its application as a screening study is expensive.
