ABSTRACT

Objective: To describe the epidemiological and clinical features of lung cancer in the INER. Methods: Retrospective study of clinical charts of patients with lung cancer attended in the INER between 1997 and 2000. Results: Adenocarcinoma was the most frequent tumor type (68.3%) in our series of 845 cases, whereas 20.7% were squamous cell carcinoma. No differences in clinical features by tumor type were found, except for a higher frequency of brain and bone metastases in patients with squamous cell carcinoma. The patients with adenocarcinoma were significantly younger and presented a lower proportion of ever smokers than patients with other tumor types (p<‹0.05). Conclusions: Adenocarcinoma was the most frequent tumor type in patients attended in the INER. The potential reasons for our findings are discussed.
