Use of denosumab in recurrent giant cell tumour of bone: Report of two cases

Abstract

Giant cell tumour of bone (GCTB) is a locally aggressive benign bone tumour. Though surgery is the mainstay of treatment, recurrence rate is 8% even after extended curettage. Recurettage does not guarantee no recurrence of the tumour. The RANKL-RANK interaction, which leads to the differentiation and functioning of the osteoclast like giant cells are responsible for the osteolytic activity of tumour. Denosumab a RANK ligand inhibitor can be used in recurrent GCTB. We report two cases, where denosumab was used in recurrent GCTB with encouraging results.
