[Treatment of malignant pleural effusion by pleurodesis with talc]

In some types of cancer (breast, lung) a malignant pleural effusion may be present during the evolution of the neoplastic disease in more than 50% of cases. The main therapeutic option for palliative purposes in these cases is chemical pleurodesis with talc. The aims of this study were to report on our experience with the use of pleurodesis with talc in the treatment of patients affected by malignant pleural effusions and to analyse the results in the short and mean term. Over the period from January 1998 to December 1999, 16 patients were included in the study. The causes of the pleural effusion were a pleural mesothelioma in 1 patient and pleural metastases in 15 patients (from lung and breast cancers in 62%). We treated 14 of these patients with talc poudrage and 2 patients with talc slurry. The talc was applied under video-assisted thorascopic management in 15 patients, while in 1 patient the talc was injected via the thoracic drainage tube. Two patients died within the first month as a result of progression of the neoplastic disease and one patient was withdrawn from the study owing to failure to collaborate. Of the other 13 patients, 11 (84%) had a total or partial response to the pleurodesis; in 9 of these patients (69.2%) the response remained stable until death, while in 2 patients the pleural effusion reappeared after 3 and 5 months, respectively. Failure of the pleurodesis occurred in 2/13 patients owing to reappearance of the pleural effusion within the first month.
