Objective To systematically evaluate the efficacy and safety of 125I seed interstitial implantation for lung cancer. Methods We searched PubMed, The Wiley Online Library, Elsevier, CNKI, VIP and WanFang Data from inception to February 2014 to collect randomized controlled trials (RCTs) of 125I seed interstitial implantation in the treatment of lung cancer. Two reviewers independently screened literature, extracted data and assessed the risk bias of included studies, and then meta-analysis was performed by using RevMan 5.1 software. Results A total of 23 RCTs involving 1 492 patients were included. The results of meta-analysis showed that:the effective rate (OR=3.43,95%CI 2.71,4.33,P<0.000 01), 1 year survival rate (OR=2.83, 95%CI 2.03 to 3.95, P<0.000 01) and 2 year survival rate (OR=2.49, 95%CI 1.60 to 3.88, P<0.000 01) in the 125I seed interstitial implantation group were higher than those in the control group, but the rate of postoperative complications was higher than that of control group (OR=19.72, 95%CI 11.63 to 33.45, P<0.000 01). In addition, there were no significant differences between both groups in the 3 year survival rate (OR=2.45, 95%CI 0.21 to 28.89, P=0.48) and the adverse reaction rate (OR=0.74, 95%CI 0.52 to 1.05, P=0.09). Conclusion 125I seed interstitial implantation is effective in the treatment of lung cancer. It can improve treatment efficiency and short-time survival rate, but may increase the rate of complications such as pneumothorax, seed malposition, bleeding and so on. Due to the limited quality and quantity of included studies, more high quality and larger sample studies are needed to verify the above conclusion.
