Single center experience on talc poudrage morbidity: focus on high talc dosage.

Malignant pleural effusion (MPE) is a common clinical problem of concern for most of the pneumologists and thoracic surgeons. A general consensus regarding the use of talc poudrage in treatment of MPE exists, but only few studies analyzed in detail talc insufflation related pulmonary morbidity. In particular, ARDS talc-related is caused by physical and chemical effects of the small talc particles (50% particle size <15 μm) and its occurrence is independent from the underlying disease, the quantity of talc used or the technique of talc instillation. In our series we observed 3 cases only (0.75%) of talc-related lung injury. This data strongly confirm the low rate of talc-related lung injury after talc poudrage in treatment of MPE regardless the amount of talc insufflated.
