[Pleurodesis in malignant pleural effusion: bleomycin vs. mitoxantrone]

In a controlled clinical trial we investigated 102 patients with malignant pleural effusion due to breast cancer, lung cancer, ovarian cancer and other tumors to compare the therapeutic effect and adverse events of pleurodesis with bleomycin (BMC) or mitoxantrone (MIT) via chest tube. Finally 96 patients had been treated according to the protocol. Age, gender, Broca index, performance score or distribution of primary tumors were not statistically different between the BMC (n = 49) or MIT group (n = 47). We found no differences between intention-to-treat and according-to-protocol groups as well. 30 days after BMC pleurodesis we found remissions of the effusion in 91% of patients (complete remission [CR] 51%, partial remission [PR] 40%), after 90 days in 83% (40% CR, 43% PR). 30 days after MIT instillation we found remission in 73% of patients (35% CR, 38% PR), after 90 days in 61% (29% CR, 32% PR) (30 and 90 days: p < 0.05). Adverse events were not different between BMC and MIT group. BMC is a safe and effective sclerosing agent for pleurodesis via chest tube.
