Abstract:Objective To evaluate the clinical effect of combination therapy with Strontium chloride and 99mTc-methylene diphosphonate on metastatic bone cancer in China. Methods A comprehensive search was performed in CAJD, CNKI (1994-2016), WANFANG (1999-2016), VIP (1989-2016) and CB Mdisc (1994-2016) databases to collect the randomized controlled trials (RCTs) in which combined therapy with Strontium chloride and 99mTc-methylene diphosphonate was applied to metastatic bone cancer in China. Meta-analysis was performed to analyze the RCTs. Results In the 16 RCTs which met the research standards, 1,366 patients were analyzed. The meta-analysis results suggested that, compared with the Strontium chloride group,bone pain, bone metastasis control and life quality were improved significantly in the combination therapy group (p < 0.05); and the adverse reactions had no significant differences between the two groups (p > 0.05). Conclusions On the basis of symptomatic and supportive treatment, the effect of combined therapy of Strontium chloride and 99mTc-methylene diphosphonate is positive for treatment of metastatic bone cancer, and better than that of simple Strontium chloride treatment.
