The present meta-analysis aimed to analyze the effect of bisphosphonates (BPs) on local recurrence of GCTB. Methods: Seven case–control studies were included by computerized searches of bibliographic databases (PubMed, AMED, EMBASE, the Cochrane library, ISI Web of Science, and China National Knowledge Infrastructure). The pooled adjusted ORs were calculated to evaluate the local recurrence of GCTB. Results: The BP group presented significantly lower total local recurrence rate than the control group in GCTB (P<0.01). Subgroup analysis shows BP group presented significantly lower local recurrence than the control group in GCTB with different tumor grades (P<0.05). In patients who underwent intralesional curettage, a significantly lower local recurrence rate was found in the BP group compared with the control group (P<0.01), but no significance was found for patients who underwent wide resection (P=0.16). None of the included studies described severe adverse effects related to BPs. Conclusion: The results confirmed the effect of BPs on reducing the local recurrence of GCTB, and the effect is not influenced by the tumor grades. BPs are benefit for the patients who underwent intralesional curettage but not recommended for those who underwent wide resection.
