ABSTRACT

Introduction: Malignant pleural effusion is a frequent complication of cancer, either primary intrathoracic or of systemic origin. During 2000, of the cases studied at the National Institute of Respiratory, Mexico, these malignant tumors were the first cause of morbidity and mortality, with 14.3% and 15.6% respectively. Objective: To identify the frequency of tumors commonly associated to malignant pleural effusion, to evaluate the utility of traditional diagnostic methods, and to correlate the effectiveness of simple thoracocentesis compared to pleural biopsy, at a third level hospital, as is the National Institute of Respiratory Diseases. Material and methods: 460 files were revised of patients with diagnosis of pleural effusion, in the period from January 1992 to December 2000. Of these, 240 met the criteria to be included in the study which were: presence of malignant cells in pleural fluid, pleural biopsy positive to malignancy, cytology and biopsy results and the frequency of the neoplasms that caused the pleural effusion were also correlate. Results: Average age was 59.1 ± 15.5, 123 men, (age 57.5 ± 16) and 117 women (60.8 ± 14.7). Diagnostic efficiency was as follows: cytology 55.7%, pleural biopsy 69.5%, thoracoscopy 95.4% and the thoracotomy of 100%. There was a correlation of 85% between cytology and histology and the most frequent tumor was adenocarcinoma. Results were compared with those published in the literature. Conclusions: Thoracoscopy and thoracotomy were the most effective diagnostic procedures. The cytology and biopsy showed less effectiveness but were similar to reports in the literature.
