BACKGROUND: Renal cell carcinoma (RCC) is among the 10 most common cancers in both men and women. It comprises 2-3% of all malignancies. The most common site for metastasis from RCC is the lung (50% of patients), followed by the skeleton (20% to 50% of patients). METHODS: We retrospectively reviewed our consecutive series of 63 patients surgically treated for spinal metastases from RCC. The surgical treatment for spinal metastases varied in each patient. Factors influencing the choice of surgery included age, disease status, symptoms, morbidity of the patient, the location, the number of repetitive lesions and the existence of extra-osseous metastases...

: Limited information is available on anti-osteoporotic treatment initiation patterns in France. In 2006-2013, the most frequently prescribed first-line treatment class for osteoporosis was represented by bisphosphonates (alendronic acid and risedronic acid), followed by strontium ranelate. Persistence with anti-osteoporotic treatment was low, with high proportions of treatment discontinuations and switches. INTRODUCTION: This epidemiological, longitudinal study described first-line treatment initiation, persistence, switches to second-line treatment, and medical care consumption in osteoporotic patients in France during the 2007-2013 period...

To overcome radioresistance in the treatment of osteosarcoma, a primary malignant tumor of the bone, radiotherapy is generally combined with radiosensitizers. The purpose of this study was to investigate a third-generation bisphosphonate, zoledronic acid (ZOL), as a radiosensitizer for osteosarcoma. We found that exposure of KHOS/NP osteosarcoma cells to 20 μM ZOL decreased the γ-radiation dose needed to kill 90% of cells. This radiosensitizing effect of ZOL was mediated through decreased mitochondrial membrane potential, increased levels of reactive oxygen species, increased DNA damage (as assessed by counting γ-H2AX foci), decreased abundance of proteins involved in DNA repair pathways (ATR, Rad52, and DNA-PKcs), and decreased phosphorylation of PI3K-Akt and MAPK pathway proteins (Raf1, MEK1/2, ERK1/2, and Akt), as compared to γ-irradiation alone...

Osteogenesis imperfecta (OI) is a group of hereditary disorders characterized by decreased bone mass and increased fracture risk. The majority of OI cases have an autosomal dominant pattern of inheritance and are usually caused by mutations in genes encoding type I collagen. OI cases of autosomal recessive inheritance are rare, and OI type XI is attributable to mutation of the FKBP10 gene. Here, we used next-generation sequencing and Sanger sequencing to detect mutations in FKBP10 and to analyze their relation to the phenotypes of OI type XI in three Chinese patients...

BACKGROUND: Osteogenesis imperfecta is caused by a genetic defect resulting in an abnormal type I collagen bone matrix which typically results in multiple fractures with little or no trauma. Bisphosphonates are used in an attempt to increase bone mineral density and reduce these fractures in people with osteogenesis imperfecta. This is an update of a previously published Cochrane Review. OBJECTIVES: To assess the effectiveness and safety of bisphosphonates in increasing bone mineral density, reducing fractures and improving clinical function in people with osteogenesis imperfecta...

OBJECTIVE: Zoledronic acid and denosumab were funded by the Australian government for the management of osteoporosis at an equivalent price to alendronate. The price of alendronate has declined by around 65 %, but the price of the other two therapies has remained stable. Using data published since the listing, this paper reports current estimates of the value of denosumab compared to alendronate from an Australian health system perspective. METHODS: A cohort-based state transition model was developed that predicted changes in bone mineral density (BMD), and calibrated fracture probabilities as a function of BMD, age and previous fracture to estimate differences in costs and QALYs gained over a 10-year time horizon...

Mesenchymal stem cell (MSC)-mediated bone regeneration is used to replace lost bone. However, methods to accelerate the process and stabilize regenerated bone remain limited. Therefore, we investigated the effect of bisphosphonates (BPs) on the function of bone marrow mesenchymal stem cells (BMMSCs) to determine if they might enhance MSC-mediated bone regeneration. We isolated and cultured BMMSCs from BALB/c mice and treated the cells with 0.1, 0.5, 1, 5, or 10 μM zoledronic acid (ZA; Zometa, a commercially available BP)...

Limited head-to-head comparative safety and effectiveness data exist between denosumab and zoledronic acid in real-world healthcare. We aimed to examine the safety and effectiveness of denosumab compared to zoledronic acid with regard to risk of serious infection and cardiovascular disease (CVD) and osteoporotic fracture. We conducted a cohort study using claims data (2009-2013) from a US commercial insurance. We included patients aged ≥50 years who newly initiated denosumab or zoledronic acid. The primary outcomes were 1) hospitalization for serious infection, 2) composite CVD endpoint including myocardial infarction, stroke, coronary revascularization, and heart failure and 3) non-vertebral osteoporotic fracture including hip, wrist, forearm and pelvic fracture...

Bisphosphonates have established their role as medical therapy for pediatric osteogenesis imperfecta (OI) patients. Since bisphosphonates have also been shown to delay tooth development in animal models, we aimed to assess whether the medication has a similar effect on children with OI. In this cross-sectional study, bisphosphonate-treated OI patients of whom dental panoramic tomograph was taken between 3 and 16years of age formed the study group. The patients, 22 in total, had been treated with pamidronate, zoledronic acid or risedronate for at least one year before the radiography...

OBJECTIVES: Bisphosphonates are widely used to treat bone diseases such as osteoporosis. However, they may cause osteonecrosis of the jaw. Here, we investigated whether in vivo exposure to bisphosphonates has a different effect on long bone and jaw osteoclasts, and on the turnover of these different bones. MATERIALS AND METHODS: Zoledronic acid (0.5 mg/kg weekly) was administered intraperitoneally to 3-month-old female mice for up to 6 months. The effects on the number of osteoclasts, bone mineralization, and bone formation were measured in the long bones and in the jaw...

Bone metastases are a frequent event in patients with solid tumors. Although great advances have been made in the treatment of these patients, the identification of novel, accurate indicators of bone response would greatly facilitate the clinical management of the disease. The receptor activator of nuclear factor-κB (RANK)/RANK ligand (RANKL)/osteoprotegerin (OPG) signaling pathway is significantly involved in bone metastasis formation. The main aim of the present study was to evaluate the role of circulating RANK, RANKL and OPG levels in predicting bone response...
