Pleurodesis using different agents in malignant pleural effusion

ObjectiveMalignant pleural effusions (MPE) are characterized by rapid reaccumulation, after tapping, and many symptoms related. Pleurodesis, for the management of MPE, is intended to achieve symphysis between parietal and visceral pleura, and to prevent relapse of pleural effusion. Many chemical agents are tried to induce abrasion and damage of the pleural mesothelial layer to achieve this symphysis.AimThe aim of this study is to compare the results of medical pleurodesis, using 4 different chemical agents in these cases, to reach an efficient one with minimal complications.MethodsBetween July 2010 and July 2012, 40 patients with MPE, divided into 4 groups, underwent medical pleurodesis using 4 chemical agents in comparison: bleomycin, doxycycline, povidone iodine and 5-fluorouracil.ResultsImmediately and for 3 months after the procedure, the results of pleurodesis were assessed and the final reported success rates were 70% for bleomycin, 80% for doxycycline and 80% for povidone iodine, while 5 fluorouracil had the lowest success rate (50%) (P-value < 0.05).ConclusionBleomycin, doxycycline and povidone iodine are nearly equally effective and safe pleurodetic agents when used in the optimal dose, while 5-fluorouracil had a much higher failure rate. Although povidone iodine and doxycycline are as effective and safe as bleomycin, they are cheaper alternatives and more available chemical agents for pleurodesis in cases with MPE.
