THE USE OF DENOSUMAB IN GIANT CELL TUMORS IN THE SACRUM
Abstract
ABSTRACT Giant Cell Tumor (GCT), a benign tumor with local aggression, corresponds to 5% of primary tumors. Fifteen percent of these are located in the sacrum. En bloc resection is an effective treatment, but when it cannot be performed, Denosumab may be indicated as an alternative treatment. The objectives of this work are: to justify the indication; determine the best dose and time of use; and recognize the need for post-treatment surgery. Methods A systematic search of clinical trials. Twenty-five articles were selected, ten of which met the inclusion criteria. The use of Denosumab is justified in advanced stages, with a dose of 120 mg administered subcutaneously, every 7 days in the first month and then maintained every 4 weeks, for 2.5 to 13 months. Adverse events are mild and can be observed in 84% of patients. With Denosumab, surgery may be less aggressive or even unnecessary. The bibliography justifies the indication of Denosumab in advanced stages of GCT, with a dose of 120 mg administered subcutaneously; there is no consensus as to the maintenance dose, which is a weekly dose in the first month and then every four weeks for 2.5 to 13 months. Complications are frequent but mild. Level of evidence III; Systematic review.
