PURPOSE: The search for an inexpensive agent for chemical pleurodesis in malignant pleural effusion (MPE) continues. We aimed to compare the efficacy and safety of iodopovidone versus doxycycline for pleurodesis in MPE.
METHODS: We randomized consecutive subjects with recurrent symptomatic MPE (1:1) to undergo pleurodesis with either doxycycline or iodopovidone administered through an intercostal tube. The primary outcome was the success rate of pleurodesis at 30 days. The secondary outcomes were the time to pleurodesis, chest pain (assessed using visual analog scale [VAS]) after pleurodesis, and complications (hypotension, acute respiratory failure, empyema).
RESULTS: We randomized 52 and 58 subjects to receive either doxycycline or iodopovidone. The mean (standard deviation [SD]) age of the study population (51% women) was 54.1 (13.6) years. Lung cancer (≥ 60%) was the most common underlying cause of MPE. We observed a similar frequency of success in the doxycycline vs. the iodopovidone group (complete response: 43 (82.7%) vs. 46 (79.3%) subjects; partial response: 7 (13.5%) vs. 10 (17.2%) subjects; p = 0.3). The mean (SD) time to pleurodesis was 1.5 (1.9) days and 1.9 (5.4) days in the doxycycline and iodopovidone groups, respectively. While the VAS for chest pain was significantly higher with iodopovidone (mean [SD] VAS: doxycycline, 31.9 [20.9]; iodopovidone, 41.3 [21.8]; p = 0.017), it did not reach the minimal clinically important difference. The complication rates were similar between the two groups.
CONCLUSION: Iodopovidone was not superior to doxycycline for pleurodesis in MPE. TRIAL REGISTRATION NUMBER/DATE: clinicaltrials.gov (NCT02583282) / October 22, 2015.
