Objective: To assess the efficacy, permanence, and safety of thoracosc
opic talc poudrage (ITP) for pleurodesis in malignant effusions, Desig
n: Retrospective. Participants: Patients with lifetime follow-up who r
eceived TTP in two related centers in Marseilles, France, Results: Thr
ee hundred sixty patients were included in this study: 88 had mesothel
ioma and 272 had pleural metastases, The mean follow-up time was 12 mo
nths (2 to 120). Of the 327 patients whose response could be evaluated
, 90.2% had a successful pleurodesis at 1 month, and 82.1% had a lifel
ong pleural symphysis. Adverse effects included 1 death 3 days after t
he procedure in a patient with end-stage disease, fever (9.8%), empyem
a (2.5%), pulmonary infection (0.8%), and malignant invasion of the sc
ar (1 patient). Conclusions: TTP is an effective and safe method of li
felong pleurodesis. It should be performed early on in the history of
malignant effusions to avoid the risk of respiratory failure, this bei
ng directly linked to the general and respiratory status of the patien
ts at the time of the procedure.
