Although adjuvant aromatase inhibitor (AI) therapy is widely used in postmenopausal women with hormone receptor-positive breast cancer, it is known to be associated with bone loss and increased fracture risk. Denosumab, a fully human monoclonal antibody against the receptor activator of nuclear factor-κB ligand, has been shown to protect against AI-induced bone loss. However, the efficacy of denosumab in the treatment of AI-associated bone loss has not been prospectively evaluated in Japan. We prospectively monitored bone mineral density (BMD) of the lumbar spine and bilateral femoral necks in 100 postmenopausal women with hormone receptor-positive postoperative breast cancer of clinical stage I-IIIA in whom treatment with AI as adjuvant endocrine therapy was planned or had been ongoing...

OBJECTIVE: Periodontitis is characterized by local inflammation leading to tooth loss and severe destruction of alveolar bone. Raloxifene is a selective estrogen receptor modulator (SERM) that halts estrogen deficiency-induced systemic bone loss in postmenopausal osteoporosis without the side effects of cancer in breast and uterus. In this study, we examined the effects of raloxifene on alveolar bone mass in a mouse model with estrogen deficiency-induced periodontitis. METHODS: Periodontitis was induced by the injection of lipopolysaccharide (LPS) into the lower gingiva in ovariectomized (OVX) mice, and the alveolar bone and femur bone mineral density (BMD) were analyzed by dual-energy X-ray absorptiometry...

Gaining an understanding of factors contributing to bone quality is key to the development of effective preventative treatments for osteoporosis and reduction in osteoporotic fractures. Oestrogen is a strong regulator of bone remodelling which maintains skeletal structural integrity. The growth regulation by oestrogen in breast cancer 1 (GREB1) gene, with an as yet undefined function, is an early response gene in the oestrogen-regulated pathway. Suggestive evidence of linkage with bone mineral density (BMD) variation has been reported with D2S168, located telomeric of GREB1...

PURPOSE: In postmenopausal women with breast cancer treated with aromatase inhibitors (AIs), most expert panels advise baseline bone mineral density testing with a dual-energy x-ray absorptiometry (DXA) scan repeated every 1 to 2 years. How often this recommendation is followed is unclear. METHODS: We performed a retrospective analysis of women with stage I to III breast cancer who started AI therapy from January 1, 2008, to December 31, 2010, with follow-up through December 31, 2012, by using the SEER-Medicare database...

BACKGROUND: The impact of long-term adjuvant therapy with aromatase inhibitors (AIs) on vertebral fracture (VF) risk is still unclear. OBJECTIVE: In this cross-sectional study, we explored the prevalence and determinants of VFs in breast cancer (BC) patients before and during AI therapy. Each woman underwent a dual-energy X-ray absorptiometry (DXA) to evaluate bone mineral density (BMD) and identify VFs by a quantitative morphometric approach. Blood samples were collected to measure serum hormone and calcium levels...

Selective estrogen receptor modulators(SERMs)have beneficial effects on the improvement of bone mineral density of the spine and hip, and decrease the vertebral fracture in postmenopausal women. Similar to patients with advanced chronic kidney disease, including dialysis patients, however, SERMs cannot decrease the risk of hip fracture, which is extremely high in Japanese dialysis patients. One of the most important disadvantages of SERMs is an increase in the risk of venous thromboembolic events and fatal stroke in high-risk groups of the Framingham Stroke Risk Score...

INTRODUCTION: Patients with breast cancer under aromatase inhibitor (AI) treatment often develop osteoporosis and their average bone loss rate is twice that of natural reduction during menopause, increasing fracture risk. As the current diagnostic technique based on bone mineral density (BMD) provides no information on bone quality, the Trabecular Bone Score (TBS) has been proposed to reflect bone microarchitecture status. The present study was designed to assess prospective changes in TBS and lumbar spine (LS) BMD in postmenopausal women with breast cancer at completion of AI treatment...

PURPOSE: Adjuvant chemotherapy has been associated with loss of bone mineral density (BMD) either as a direct effect or due to glucocorticoids used as supportive care medication. A prospective cohort study was conducted to evaluate changes in BMD from baseline to right after completion of chemotherapy, i.e., 4 months. METHODS: Dual-imaging X-ray absorptiometry (DXA) was performed at baseline and after completing anthracycline- and taxane-based chemotherapy to measure BMD in the spine, hip, and forearm in early-stage breast cancer patients...

Treatment of osteoporosis is aimed to prevent fragility fractures and to stabilize or increase bone mineral density. Several drugs with different efficacy and safety profiles are available. The long-term therapeutic strategy should be planned, and the initial treatment should be selected according to the individual site-specific fracture risk and the need to give the maximal protection when the fracture risk is highest (i.e. in the late life). The present consensus focused on the strategies for the treatment of postmenopausal osteoporosis taking into consideration all the drugs available for this purpose...

Postmenopausal women with breast cancer on aromatase inhibitor (AI) treatment are at increased risk of bone mineral density loss, which may lead to minimal trauma fractures. We examined the cost-effectiveness of dual energy X-ray absorptiometry (DXA) with antiresorptive (AR) therapy compared with fracture risk assessment, lifestyle advice, and vitamin supplementation. We used a hypothetical Markov cohort model of lifetime duration for 60-year-old women with early stage breast cancer receiving AIs. The data to inform the model came from medical literature, epidemiological reports, and costing data sets...

Breast cancer is the most commonly diagnosed cancer among women, but despite survival rates improvement, it is still the second major cause of cancer related death. In postmenopausal women with estrogen receptor (ER) dependent breast cancer, hormone therapy is an option, either by direct inhibition of ER using tamoxifen or by aromatase inhibition, resulting in decreased estrogen production. In this paper these two endocrine therapy approaches are compared in terms of their impact on bone health. Guidance for the prevention of bone loss and occurrence of fractures in postmenopausal women receiving AIs is also proposed...

Cysteine (Cys) is well known to be involved in oxidation-reduction reactions, serving as a source of sulfides in the body. Amino acids are known to improve menopausal symptoms and significantly reduce morbidity. This study aims to find an unrevealed effect of Cys with estrogenic and osteogenic actions. Ovariectomized (OVX) mice were treated with Cys daily for 8 weeks. Estrogen-related and osteoporosis-related factors were analyzed in the vagina, serum, and tibia. Cys was treated in estrogen receptor (ER)-positive human osteoblast-like MG-63 cells and ER-positive human breast cancer Michigan Cancer Foundation-7 (MCF-7) cells...
