Clinicopathologic Characteristics of Giant Cell Tumor of Bone with Malignant Transformation (Poster Board Number: 46; LACC West Exhibit Hall A) - Dec 13, 2021 - Abstract #USCAP2022USCAP_1307; In this cohort, 4 of 13 patients were known to have denosumab treatment prior to sarcomatous transformation of GCTB. Additional investigations are needed to better characterize underlying mechanisms in sarcomatous transformation.

Enrollment change, Trial termination: Pilot Study of Denosumab in BRCA1/2 Mutation Carriers Scheduled for Risk-Reducing Salpingo-Oophorectomy (clinicaltrials.gov) - Dec 8, 2021 P1, N=1, Terminated, Additional investigations are needed to better characterize underlying mechanisms in sarcomatous transformation. N=60 --> 1 | Suspended --> Terminated; it was decided that due to lack of accrual on the trial, and low potential for accruing over the near future, the trial will be shut down.

Clinical, Journal: Promoting bone health in children and adolescents following solid organ transplantation. (Pubmed Central) - Dec 1, 2021 Dual-energy X-ray absorptiometry can be useful to detect abnormal bone mass and fracture risk in this population and newer bone assessment methods are being evaluated in children at risk for poor bone outcomes. Newer bone therapies being explored in adults with transplants, particularly bisphosphonates and the RANKL inhibitor denosumab, may offer promise for children with low bone mass post-transplantation.

Journal: Metastasectomy Versus Non-Metastasectomy for Giant Cell Tumor of Bone Lung Metastases. (Pubmed Central) - Nov 29, 2021 The biological behaviors and clinical courses of lung metastases are difficult to predict, and their treatment recommendations vary, including metastasectomy and non-metastasectomy with chemotherapy (denosumab, interferon-alfa, bisphosphonates), with radiation therapy, or with observation alone...[Orthopedics. 2021;44(x):xx-xx.].

Review, Journal: Hypercalcemia following discontinuation of denosumab therapy: A systematic review. (Pubmed Central) - Nov 29, 2021 These results may further underscore that high bone formation and bone turnover rates are critically associated with hypercalcemia after the discontinuation of denosumab. In contrast, given that not all skeletally immature patients develop hypercalcemia, it is probable that other unidentified factors are involved in the pathology of this condition.

NEOADJUVANT DENOSUMAB IN GCT. LONG TERM INJECTION CAN DECREASE THE RISK OF LOCAL RECURRENCE ([VIRTUAL]) - Nov 26, 2021 - Abstract #CTOS2021CTOS_364; The minimum number of neoadjuvant denosumab is determined, which reduces the risk of LR in a case of attenuated surgery. Despite an increase of LR rate (statistically insignificant, p > 0.05) combined treatment with neoadjuvant denosumab for patients with anatomically complex localization of GCT is the preferred method, especially with high risks of postoperative complications after mutilating surgery.

Clinical, Journal: The incidence of medication-related osteonecrosis of the jaw following tooth extraction in patients prescribed oral bisphosphonates. (Pubmed Central) - Nov 25, 2021 Patients with previous or current exposure to intravenous bisphosphonates, denosumab, novel-targeted chemotherapies used in the oncology setting or radiotherapy to the head and neck were excluded from this study.Results The incidence of medication-related osteonecrosis of the jaw following tooth extraction in this group of 652 was 0.8%. A significantly increased risk of developing medication-related osteonecrosis of the jaw was evident in patients prescribed oral bisphosphonates for four years or more (p = 0.02), with an incidence in this group of 1.6%.Conclusion This study demonstrates that, following dental extraction, patients who are prescribed oral bisphosphonates are at risk of developing medication-related osteonecrosis of the jaw and that this risk increases significantly when the patient has been taking the bisphosphonate for four years or more.

Journal: Denosumab versus romosozumab for postmenopausal osteoporosis treatment. (Pubmed Central) - Nov 24, 2021 Adverse events were few and predominantly minor in both groups, with no remarkable difference in the incidence of new vertebral fractures. Romosozumab showed a higher potential for improving BMD than denosumab in this clinical study of postmenopausal osteoporosis patient treatment.

Clinical, Observational data, Journal, HEOR: Influence of Preventive Tooth Extractions on Quality of Life in Patients with Antiresorptive Intake-A Prospective Longitudinal Study. (Pubmed Central) - Nov 24, 2021 Patients were stratified as high-risk (malignant disease with bone metastasis or multiple myeloma, with monthly high-dose antiresorptive therapy delivered intravenously [bisphosphonate] or subcutaneously [denosumab]) and low-risk/osteoporosis patients (weekly low-dose antiresorptive therapy administered orally [bisphosphonate] or half-yearly subcutaneously [denosumab])...Therefore, if indicated, preventive tooth extraction should not be omitted. Patient-oriented outcome measures are important to obtain a good risk-benefit balance for patient-specific treatment.

Clinical, Journal: Efficacy of Antiosteoporotic Medications in Patients With Rebound-Associated Fractures After Denosumab Discontinuation. (Pubmed Central) - Nov 21, 2021 Three patients sustained additional fractures despite treatment reinstitution (2 with zoledronate and 1 with teriparatide). Among patients with RAVFs following denosumab discontinuation both antiresorptive (zoledronate and denosumab) and anabolic (teriparatide) treatment as well as the combination of denosumab with teriparatide seem to be effective in terms of BMD response.

Transforming non metastatic in metastatic prostate cancer () - Nov 20, 2021 - Abstract #PROSCABLADDR2021PROSCA_BLADDR_1; We choose to classify the patient as a mCRPC TREATMENT As first line treatment for mCPRC patient we decided to start on Enzalutamide + Denosumab COMMENT In Spartan and Prosper trials the incidence of fractures reaches up to 18%, and Darolutamide is not available in Argentina. With the PET-CT PSMA we “transformed” this patient into a mCPRC one and we could treat him with a better bone protection therapy (denosumab 120 mg every 4 weeks or Zoledrinic ac 4 mg every 4 weeks).

Retrospective data, Journal: Recurrent giant cell tumour of the distal ulna after en bloc resection with preoperative denosumab use. (Pubmed Central) - Nov 17, 2021 There are a few reports of recurrent cases after en bloc resection; however, the association with the use of denosumab is unknown. We present the clinical, radiological and histopathological findings of a case of Campanacci grade III GCTB at the distal end of the ulna, which resulted in soft tissue recurrence after en bloc resection with the preoperative use of denosumab.

Journal: On the effect of antiresorptive drugs on the bone remodeling of the mandible after dental implantation: a mathematical model. (Pubmed Central) - Nov 17, 2021 We show that using antiresorptive agents such as bisphosphonates or denosumab increases bone density and the associated mechanical properties, but at the same time, it also increases bone brittleness. We conclude that, despite the many limitations of these very complex models, the one presented here is capable of predicting qualitatively the evolution of some of the main biological and chemical variables associated with the process of bone remodeling in patients receiving drugs for osteoporosis, so it could be used to optimize dental implant design and coating for osteoporotic patients, as well as the drug dosage protocol for patient-specific treatments.
