Background: Autologous blood is a novel, high-efficacy sclerosant for treatment of malignant pleural effusion (MPE), similar to tetracycline. There has been no comparative data between autologous blood and a worldwide sclerosant like talc. We aimed to compare the effectiveness of autologous blood versus talc pleurodesis. Methods: A prospective study was conducted at Songklanagarind Hospital, Songkhla, Thailand. A total of 123 symptomatic MPE cases were randomized to receive autologous blood pleurodesis (ABP) versus pleurodesis with talc slurry. In the ABP group, 100 ml of autologous venous blood was instilled through a chest drain, followed by 50 ml of sterile normal saline (NSS). In the talc group, 20 ml of 1% lidocaine diluted in 30 ml NSS was instilled, followed by 4 g of sterile talc (Steritalc®, a non-small particle size talc) suspended in 100 ml of NSS. A 30-day pleurodesis efficacy (according to Paladine’s criteria), along with the adverse events, was evaluated. Results: Fifty-six cases in the ABP, and 54 cases in the talc group completed the study. There was no difference between the two groups in the demographic data. The overall pleurodesis success rate at 30 days was 82.0% in the ABP group, comparable to the talc pleurodesis group (87.0%, p = 0.12). The percentage of fever (9.0% versus 28.0%, p = 0.04), amount of acetaminophen required by each participant (2.2 ± 0.7 versus 4.6 ± 0.9 tablets, p = 0.03), pain score and percentage of cases who needed opioids (9.0% versus 26.0%, p = 0.02) and hospital stay (10.2 ± 2.7 versus 12.8 ± 3.4, p = 0.04) were significantly lower in the ABP group; no infectious or serious events occurred. Conclusions: ABP had an equivalent efficacy compared to talc pleurodesis for MPE treatment. ABP offered less fever and pain and could shorten hospital stays, and neither produced means ABP did not produce clotted drainage, pulmonary or systemic adverse events.
