    Abstract:
    OBJECTIVES: This meta-analysis aimed at determining the association between preoperative denosumab and the risk of local recurrence in patients with giant cell tumors of the bone. METHODS AND MATERIALS: Web of Science, EMBASE, Cochrane Library, and PubMed were comprehensively searched on April 20th, 2022. Data from the included articles were analyzed using meta-analysis. The bias of all included studies was evaluated according to ROBINS-I. Also, subgroup and sensitivity analyses were performed. RESULTS: Eight studies with 1270 cases (195 in the denosumab group and 1075 in the control group) were eventually included. Patients receiving denosumab before curettage had a higher risk of local recurrence than those who underwent curettage alone (odds ratio: 2.29, 95% confidence intervals: 1.44-3.64, P = 0.0005). The denosumab group showed a significantly higher risk of local recurrence in most subgroup analyses, except for those with preoperative denosumab duration ≤six months/doses (P = 0.66) and sample size ranging from 100 to 180 (P = 0.69). CONCLUSION: Denosumab before curettage may increase the risk of local recurrence in patients with giant cell tumor of the bone. Preoperative denosumab should be used with caution after weighing an increased risk of local recurrence against the clinical benefits and a duration time of less than six months before surgery is recommended.
