Brief Summary
Giant cell tumor of bone (GCTb) is a primary, osteolytic, benign tumor of the bone. Surgery is the commonly used treatment. Discovery of RANKL and its human monoclonal antibody, denosumab, led to use of denosumab for treatment of GCT. The aim of this study was to evaluate clinical and pathological results of treatment of relapsed or refractoriness GCT with denosumab and to assess adverse effect profile and recurrence rate.

Outcome Measures
Primary Outcomes (2)
Molecular analysis (Immunohistochemistry for RANKL, RANK, OPG,Col-I, VEGF)
For collagen RANKL (Receptor Activator for Nuclear Factor-κ B Ligand), RANK (Receptor Activator for Nuclear Factor-κ B), OPG (Osteoprotegerin), Col-I (type I Collagen), VEGF (Vascular Endothelial Growth Factor) immunohistochemistry, sections were deparaffinized, rehydrated, and immunostained with a SA1024 SABC-POD kit and Kit-0017 DAB detection kit. Briefly, antigen retrieval was performed, and endogenous peroxidases were then inactivated prior to incubation with primary antibodies overnight at 4°C. This was followed by incubation with a biotinylated secondary antibody and a streptavidin-biotin complex peroxidase solution. Diaminobenzidine (DAB) chromogen was applied and counterstained with hematoxylin for antibody detection. Images were captured by a microscope system at 400-magnification. The integrated optical density values of each factor were semiquantitatively analyzed using Imaging Pro Plus 6.0 software.
6 month
Molecular analysis (RT-PCR for RANKL, RANK, OPG,Col-I, VEGF)
Tissures mRNA was extracted using TRIzol reagent (Invitrogen, Carlsbad, CA). The RNA concentration and quality were assessed using a Quawell Q5000 spectrophotometer (Quawell, San Jose, CA). Reverse transcription PCR was performed using a Gene Amp 7700 Sequence Detection System (Applied Biosystems, Foster City, CA) and custom-designed, validated primers for Col1α1, Col2α1, Aggrecan, MMP-13, and ADAMTS-4. GAPDH was used as the housekeeping gene. Relative gene expression changes were reported using the 2(-Delta Delta C(T)) method as previously described. The experiment was repeated in triplicate to ensure accuracy.

Interventions
Denosumab (trade names Prolia and Xgeva) is a human monoclonal antibody for the treatment of osteoporosis, treatment-induced bone loss, metastases to bone, and giant cell tumor of bone.Denosumab is a RANKL inhibitor, which works by preventing the development of osteoclasts which are cells that break down bone.
