Abstract
Breast cancer stands as a prominent contributor to cancer-related fatalities among women globally, characterized by an unfavorable prognosis, low survival rates, and its conventional treatment approach involving chemotherapy. Doxorubicin (DOXO) represents a potent anti-tumor agent widely employed in combating breast cancer. Regrettably, a substantial proportion of patients eventually develop resistance to DOXO treatment, elevating the risk of relapse and adverse clinical outcomes. Omega-3 polyunsaturated fatty acids (n-3 PUFAs), recognized as essential components of the human diet, have exhibited considerable promise in targeting malignant cells, initiating apoptosis, and impeding tumor proliferation and metastatic dissemination. Combining these nutritional supplements, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), with DOXO presents a compelling strategy to augment treatment efficacy. The present study was conducted employing a breast cancer cell line, MCF-7, to assess the synergistic potential of DHA, EPA, and DOXO. Remarkably, the combination treatment yielded a substantial increase in cytotoxicity compared to the administration of DOXO alone. Furthermore, an enhancement in the suppression of metastasis was evident in the combination treatment relative to the exclusive use of DOXO. Cell cycle analysis unveiled that cells subjected to the combination treatment exhibited a more pronounced arrest in the G1 phase, signifying the combination's heightened effectiveness in impeding cell progression into the doubling phase. Collectively, the amalgamation of n-3 polyunsaturated fatty acids (n-3 PUFAs) emerges as a potent strategy for enhancing the therapeutic potential of DOXO, effectively restraining the growth and dissemination of breast cancer cells.

Brown RB, Bigelow P, Dubin JA. Breast Cancer and Bone Mineral Density in a U.S. Cohort of Middle-Aged Women: Associations with Phosphate Toxicity. Cancers (Basel) 2023; 15:5093. [PMID: 37894460 PMCID: PMC10604967 DOI: 10.3390/cancers15205093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2023] [Revised: 10/10/2023] [Accepted: 10/19/2023] [Indexed: 10/29/2023] Open
Abstract
Breast cancer is associated with phosphate toxicity, the toxic effect from dysregulated phosphate metabolism that can stimulate tumorigenesis. Phosphate toxicity and dysregulated phosphate metabolism are also associated with bone mineral abnormalities, including excessive bone mineral loss and deposition. Based on shared associations with dysregulated phosphate metabolism and phosphate toxicity, a hypothesis proposed in the present mixed methods-grounded theory study posits that middle-aged women with incidence of breast cancer had a greater magnitude of changes in bone mineral density over time compared with women who remained cancer-free. To test this hypothesis, a mixed-effects model was used to analyze the associations of breast cancer incidence with spinal bone mineral density changes in the U.S. Study of Women's Health Across the Nation. Compared with women in the cohort who remained cancer-free, women who self-reported breast cancer had higher bone mineral density at baseline, but had more rapid losses in bone mineral density during follow-up visits. These findings agree with the hypothesis that a greater magnitude of changes in bone mineral density over time is associated with breast cancer in a cohort of middle-aged women. The findings also have implications for studies investigating dysregulated phosphate metabolism and phosphate toxicity as causative factors of bone metastasis in metastatic breast cancer. Additionally, the authors previously found increased breast cancer risk associated with high dietary phosphate intake in the same cohort of middle-aged women, and more studies should investigate a low-phosphorus diet to reduce bone mineral abnormalities and tumorigenesis in breast cancer patients.

Effect of chemotherapy and different chemotherapy regimens on bone health among Chinese breast cancer women in different menstrual status: a self-control study. Support Care Cancer 2023; 31:540. [PMID: 37642751 DOI: 10.1007/s00520-023-07960-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2023] [Accepted: 07/20/2023] [Indexed: 08/31/2023]
Abstract
PURPOSE Although the therapy-related bone loss attracts increasing attention nowadays, the differences in chemotherapy-induced bone loss and bone metabolism indexes change among breast cancer (BC) women with different menstrual statuses or chemotherapy regimens are unknown. The aim of the study is to explore the effects of different regimens of chemotherapy on bone health. METHOD The self-control study enrolled 118 initially diagnosed BC women without distant metastasis who underwent dual-energy X-ray absorptiometry (DXA) bone mineral density (BMD) screening and (or) bone metabolism index monitoring during chemotherapy at Chongqing Breast Cancer Center. Mann-Whitney U test, Cochran's Q test, and Wilcoxon sign rank test were performed. RESULTS After chemotherapy, the BMD in the lumbar 1-4 and whole lumbar statistically decreased (- 1.8%/per 6 months), leading to a significantly increased proportion of osteoporosis (27.1% vs. 20.5%, P < 0.05), which were mainly seen in the premenopausal group (- 7.0%/per 6 months). Of the chemotherapeutic regimens of EC (epirubicin + cyclophosphamide), TC (docetaxel + cyclophosphamide), TEC (docetaxel + epirubicin + cyclophosphamide), and EC-T(H) [epirubicin + cyclophosphamide-docetaxel and/or trastuzumab], EC regimen had the least adverse impact on BMD, while the EC-TH regimen reduced BMD most (P < 0.05) inspite of the non-statistical difference between EC-T regimen, which was mainly seen in the postmenopausal group. Chemotherapy-induced amenorrhea (estradiol 94 pg/ml vs, 22 pg/ml; FSH 9.33 mIU/ml vs. 61.27 mIU/ml) was proved in premenopausal subgroup (P < 0.001). Except the postmenopausal population with calcium/VitD supplement, the albumin-adjusted calcium increased significantly (2.21 mmol/l vs. 2.33 mmol/l, P < 0.05) after chemotherapy. In postmenopausal group with calcium/VitD supplement, β-CTX decreased significantly (0.56 ng/ml vs. 0.39 ng/ml, P < 0.05) and BMD were not affected by chemotherapy (P > 0. 05). In premenopausal group with calcium/VitD supplement, PTH decreased significantly (52.90 pg/ml vs. 28.80 pg/ml, P = 0. 008) and hip BMD increased after chemotherapy (0.845 g/m2 vs. 0.952 g/m2, P = 0. 006). As for both postmenopausal and premenopausal group without calcium/VitD supplement, there was a significant decrease in bone mass in hip and lumbar vertebrae after chemotherapy (0.831 g/m2 vs. 0.776 g/m2; 0.895 g/m2 vs. 0.870 g/m2, P < 0.05). CONCLUSION Chemotherapy might induce lumbar vertebrae BMD loss and spine osteoporosis with regimen differences among Chinese BC patients. Calcium/VitD supplementation could improve bone turnover markers, bone metabolism indicators, and bone mineral density. Early interventions on bone health are needed for BC patients during chemotherapy.

Abstract
Osteoporosis is a chronic skeletal condition characterized by low bone mass and deteriorated microarchitecture of bone tissue and puts tens of millions of people at high risk of fractures. New therapeutic agents like i-bodies, a class of next-generation single-domain antibodies, are needed to overcome some limitations of conventional treatments. An i-body is a human immunoglobulin scaffold with two long binding loops that mimic the shape and position of those found in shark antibodies, the variable new antigen receptors of sharks. Its small size (∼12 kDa) and long binding loops provide access to drug targets, which are considered undruggable by traditional monoclonal antibodies. Here, we have successfully identified a human receptor activator of nuclear factor-κB ligand (RANKL) i-body, ADR3, which demonstrates a high binding affinity to human RANKL (hRANKL) with no adverse effect on the survival or proliferation of bone marrow-derived macrophages. Differential scanning fluorimetry suggested that ADR3 is stable and able to tolerate a wide range of physical environments (including both temperature and pH). In addition, in vitro studies showed a dose-dependent inhibitory effect of ADR3 on osteoclast differentiation, podosome belt formation, and bone resorption activity. Further investigation on the mechanism of action of ADR3 revealed that it can inhibit hRANKL-mediated signaling pathways, supporting the in vitro functional observations. These clues collectively indicate that hRANKL antagonist ADR3 attenuates osteoclast differentiation and bone resorption, with the potential to serve as a novel therapeutic to protect against bone loss.

Dhabhar B. Cancer Treatment-Induced Bone Loss: Role of Denosumab in Non-Metastatic Breast Cancer. BREAST CANCER: TARGETS AND THERAPY 2022; 14:163-173. [PMID: 35860287 PMCID: PMC9292456 DOI: 10.2147/bctt.s353332] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Accepted: 03/25/2022] [Indexed: 12/09/2022]
Abstract
Chemotherapeutic agents, endocrine therapy and radiotherapy used in the management of breast cancer are known to cause decreased bone mineral density, and thus, increased incidence of fractures. A majority (~60%) of the breast cancer patients in India are either estrogen (ER) or progesterone hormone receptor (PR) positive. Adjuvant treatment with aromatase inhibitors (AIs) is the treatment mainstay for hormone-sensitive disease in postmenopausal (PM) women, with reduced bone mineral density (BMD), which results in increased fracture rates. Zoledronic acid, alendronate, risedronate and denosumab have been the agents of choice for managing bone loss. Denosumab 60 mg is approved for gaining bone mass in women with breast cancer who are at high risk for fracture following adjuvant AI treatment. The phase III HALT-BC data indicate an improvement in BMD with denosumab and a 50% reduction in clinical fractures, with significant improvements seen at the lumbar spine, distal third of the radius, and total hip. Denosumab has several advantages over other bone modifying agents such as subcutaneous self-administration by the patient themselves, no requirement of hospitalization, no dose modifications in renal impairment, and low incidence of acute phase anaphylactic reactions. We review the available evidence of denosumab for managing bone loss in non-metastatic breast cancer patients.

Abstract
OBJECTIVE To evaluate the effectiveness of exercise for improving bone-related outcomes among cancer survivors. DESIGN Systematic review and meta-analysis. METHODS An electronic search using the following databases: SPORTDiscus, Science Direct, CINAHL, MEDLINE, Cochrane, Pubmed, Ebscohost, ProQuest Nursing and Allied Health Source. Randomised, controlled, exercise trials involving cancer survivors were eligible. Effect data on bone mineral content (BMC) and density (BMD) outcomes were extracted. Risk of bias was assessed using the Physiotherapy Evidence Database tool. Standardised mean differences (SMD) were calculated to compare differences between exercise and usual care. Subgroup analyses were conducted to assess whether effect differed by exercise mode, intervention length, supervision, treatment, cancer type and risk of bias. RESULTS Twenty-six trials were included, with intervention durations ranging between 12 weeks and 2 years. Most trials involved breast cancer (n = 13, 50%), and most interventions were supervised (n = 18, 69%) and evaluated mixed-mode (i.e., combined aerobic and resistance) exercise (n = 13, 50%). Significant effects in favour of exercise (aerobic, resistance, mixed-mode and other exercise) were observed for whole body BMD, hip BMD, trochanter BMD and femoral neck BMD (SMD range: 0.19-0.39, all p < 0.05) compared to usual care. CONCLUSION Participation in various modes (aerobic, resistance, mixed-mode and other) of supervised and unsupervised exercise is associated with improvements in BMD. The present results provide evidence for clinicians and other health care professionals (e.g., exercise physiologists and physiotherapists) to recommend exercise for cancer survivors to prevent bone loss during and following treatment.

Abstract
BACKGROUND Breast cancer is the most commonly occurring cancer in women worldwide. Early breast cancer is a kind of invasive neoplasm that has not proliferated beyond the breast or the axillary lymph nodes. Current therapeutic strategies for breast cancer mainly include local therapies such as surgery or radiotherapy and systemic therapies like chemotherapy, endocrine, and targeted therapy.Nowadays, the adjuvant treatment for hormone receptor-positive early breast cancer in postmenopausal women remains the main effective systemic therapy which can improve disease-free survival and overall survival; it involves several endocrine treatment regimens including selective estrogen receptor modulators (SERMs), aromatase inhibitors (AIs), or a combination of them. AIs have been shown to be more effective in preventing recurrence in postmenopausal women with early breast cancer when compared with tamoxifen, thus representing the standard of care for adjuvant endocrine therapy. Although AIs are usually well-tolerated, they can have some side effects. Apart from the appearance of arthralgias or myalgias and cardiovascular events, AI therapies, reducing already low endogenous postmenopausal estradiol levels, cause increased bone loss and increase fracture risk in postmenopausal women. OBJECTIVES To evaluate the therapeutic options in the management of aromatase inhibitor-associated bone loss (AIBL). METHODS We reviewed the current literature dealing with different therapeutic options in the treatment of AIBL. RESULTS Clinical practice guidelines recommend a careful evaluation of skeletal health in all women with breast cancer before AI therapy initiation. Adequate calcium and vitamin D intake have also been suggested. Pharmacological attempts to minimize AI-related bone loss have focused on the use of antiresorptive agents, such as bisphosphonates and denosumab, to protect bone integrity and reduce the risk of fractures. Furthermore, clinical trials have shown that by making the bone microenvironment less susceptible to breast cancer metastasis, these drugs are able to increase disease-free survival. CONCLUSIONS AI, thatare the pillar of the systemic treatment for patients with hormone receptor-positive breast cancer, are associated with different side effects, and in particular osteoporosis and fractures. Both bisphosphonates and denosumab are able to prevent this negative effect.

Abstract
Background Increased bone turnover is frequently observed in advanced cancer and predominantly related to bone metastases or therapy. Cachexia represents an important cause of morbidity and mortality in cancer patients. Key features are weight loss, muscle wasting and chronic inflammation, which induce profound metabolic changes in several organs, including the bone. However, whether cachexia contributes to abnormal bone metabolism in cancer patients is unknown. Aim of the present study was to determine the potential correlation of bone turnover markers with body composition and laboratory parameters in treatment-naïve cancer patients. Methods In this cross-sectional study we measured the levels of carboxy terminal telopeptide of collagen (CTX), an indicator of bone resorption, as well as osteocalcin (Ocn) and procollagen type I N-terminal propeptide (PINP), indicators of bone formation, in 52 cancer patients and correlated with body composition and laboratory parameters. Univariate and multivariate logistic analysis were performed to identify determinants of negative bone remodeling balance, estimated by CTX/Ocn and CTX/PINP ratio. Results Based on weight loss, body mass index and muscle mass, patients were divided into a cachectic (59.6%) and a control (40.4%) group. After correcting for the presence of bone metastases, our results showed a significant upregulation of CTX in cachectic patients compared to non-cachectic cancer patients (median 0.38 vs 0.27 ng/mL, p < 0.05), with no difference in Ocn and PINP levels (mean 14 vs. 16 ng/ml, p = 0.2 and median 32 vs. 26 μg/L, p = 0.5, respectively). In addition, the CTX/Ocn and the CTX/PINP ratio were indicative of bone resorption in 68% and 60% of cachexia patients, respectively (vs. 20% and 31% in the control group, p = 0.002 and p = 0.06). The main determinants of the unbalanced bone turnover were hypoalbuminemia for the CTX/Ocn ratio (OR 19.8, p < 0.01) and high CRP for the CTX/PINP ratio (OR 5.3, p < 0.01) in the multivariate regression analysis. Conclusions CTX is substantially higher in cachectic patients compared to non-cachectic oncological patients and hypoalbuminemia as well as elevated CRP concentrations are independent predictors of a negative bone remodeling balance in cancer patients. These results strongly indicate that cachexia correlates with exacerbated bone turnover in cancer.

Abstract
Survivors of breast cancer (BC) are at increased risk of chronic diseases due to factors such as low bone mineral density (BMD) and loss of muscle mass (MM) coupled with increased fat mass (FM). It is important to know that healthy behaviors can mitigate the risk of these complications. A narrative review was performed using PubMed and ScienceDirect to identify diet and physical activity (PA) interventions aimed at improving BMD, MM, and/or FM in female BC survivors. Data from 2000 to 2018 were used and 17 diet and/or PA interventions were identified. The duration of interventions was from 3 weeks until 24 months, the smallest sample was 26 women, and the largest was 223. The ranging age of participants was from 46 to 64 years. Studies with a longer duration, in-person modality and/or that used behavioral models showed better results. In BMD, the best results in spine were observed at 24 months in a face-to-face intervention (increase of 3.08%). Regarding MM, the greatest increase was at 26 weeks under Cognitive Behavioral Therapy (CBT) in person (43.8 ± 8.7 to 44.7 ± 8.4 kg, p = 0.04). This approach also showed the greatest decrease in FM from 36.7 to 31.2 kg in 4 months (p ≤ 0.01). Improving BMD and MM and preventing the increase of FM is a challenge for public health. More studies are needed to improve BMD among BC survivors and consider strategies that have yielded better results to promote healthy changes.Key teaching pointsBreast cancer survivors are at increased risk for low bone mineral density, loss of muscle mass, and increased fat mass due to the treatments received; the adoption of a healthy diet and physical activity can mitigate these complications.Of the 17 studies included, 8 used the face-to-face modality, 7 combined face-to-face with phone calls and two studies used only phone calls and email; studies that used the face-to-face modality showed better results.For bone mineral density, the best results were observed in spine at 24 months (increase of 3.08%) in a face-to-face intervention.The greatest increase in muscle mass (43.8 to 44.7 kg) was at 26 weeks in a physical activity intervention; the larger amount of fat mass loss was 5.5 kg in a diet and physical activity intervention. Both results were obtained using the Cognitive Behavioral Therapy (CBT) in person.Lifestyle interventions to maintain or improve bone mineral density, muscle mass and fat mass are effective at least for one of these three variables.

Working cancer survivors' physical and mental characteristics compared to cancer-free workers in Japan: a nationwide general population-based study. J Cancer Surviv 2021; 15:912-921. [PMID: 33433855 PMCID: PMC8519890 DOI: 10.1007/s11764-020-00984-7] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Accepted: 12/08/2020] [Indexed: 12/25/2022]
Abstract
PURPOSE This study compared working cancer survivors' self-rated health status (SRHS), physical functional capacity, depressive symptoms, and happiness to those of cancer-free workers. METHODS A nationwide general population-based cross-sectional study on a sample of Japanese was conducted. Prevalence of deteriorated SRHS, restricted physical functional capacity, depressive symptoms, and perceived happiness were compared between working cancer survivors and cancer-free workers with multivariable logistic regression analysis adjusted for age and sociodemographic and health-related backgrounds. RESULTS Of the 28,311 male and 26,068 female workers, 977 (3.5%) and 1267 (4.9%) were cancer survivors, respectively. Working cancer survivors reported deteriorated SRHS more frequently than cancer-free workers: 21.3% vs. 13.8%, multivariable-adjusted odds ratio (95% confidence interval), 1.64 (1.39-1.95) for men, 23.8% vs. 17.5%, 1.34 (1.16-1.54) for women. Restricted physical functional capacity was reported more frequently in working cancer survivors than cancer-free workers: 6.8% vs. 2.6%, 1.76 (1.34-2.32) for men, 4.9% vs. 2.0%, 2.06 (1.56-2.71) for women. No significant difference was found for depressive symptoms: 21.6% vs. 22.9% in men, 30.0% vs. 28.5% in women. Working cancer survivors felt happiness more frequently than cancer-free survivors in men (77.3% vs. 71.7%, 1.21 (1.01-1.45)) but not in women (76.1% vs. 74.9%). CONCLUSIONS Working cancer survivors had worse SRHS and more restricted physical functional capacity than cancer-free workers. In men, working cancer survivors felt happiness more frequently than cancer-free workers. IMPLICATIONS FOR CANCER SURVIVORS Continuous support to improve cancer survivors' SRHS and physical functional capacity would be necessary even while they are working.

Abstract
OBJECTIVE To describe the natural history, reconstructive solutions, and functional outcomes of those men undergoing pubectomy and urinary reconstruction after prostate cancer treatment. PATIENTS AND METHODS This study retrospectively identified 25 patients with a diagnosis of urosymphyseal fistula (UF) following prostate cancer therapy who were treated with urinary reconstruction with pubectomy. This study describes the natural history, reconstructive solutions, and functional outcomes of this cohort. RESULTS All 25 patients had a history of pelvic radiotherapy for prostate cancer. The median (interquartile range [IQR]) time from prostate cancer treatment to diagnosis of UF was 11 (6, 16.5) years. The vast majority of men (24/25; 96%) presented with debilitating groin pain during ambulation. Posterior urethral stenosis was common (20/25; 80%), with 60% having repetitive endoscopic treatments. Culture of pubic bone specimens demonstrated active infection in 80%. Discordance between preoperative urine and intraoperative bone cultures was common, 21/22 (95.5%). After surgery, major 90-day complications (Clavien-Dindo Grade III and IV) occurred in eight (32%) patients. Pain was significantly improved, with resolution of pain (24/25; 96%) and restoration of function, the median (IQR) preoperative Eastern Cooperative Oncology Group Performance Status (ECOG PS) was 3 (2, 3) vs median postoperative ECOG PS score of 0 (0, 1). CONCLUSION Endoscopic urethral manipulation after radiation for prostate cancer is a risk factor for UF. Conservative management will not provide symptom resolution. Fistula decompression, bone resection, and urinary reconstruction effectively treats chronic infection, improves pain and ECOG PS scores.

Abstract
Background Osteopenia/osteoporosis, characterized by low bone mineral density (BMD), is a potential prognostic factor in cancer patients. We conducted a retrospective single-institution study to evaluate the prognostic impact of preoperative low BMD on colorectal liver metastases (CRLM) in patients undergoing liver resection. Methods BMD was assessed in 281 patients undergoing initial liver resection for CRLM by analyzing the preoperative computed tomography (CT) images at the level of the eleventh thoracic vertebra as the region of interest. Survival outcomes were compared between the two groups divided by the median BMD value and prognostic factors after surgery were assessed. Propensity score-based inverse probability weighting (IPW) was applied to adjust for between-group differences in baseline characteristics. Results The low BMD group had significantly more older patients (≥75 years) (P=0.01) and a higher incidence of bilobar metastases (P=0.005) than the normal BMD group. After IPW adjustment, overall survival (OS) was significantly poorer (P=0.02) and recurrence-free survival was slightly poorer (P=0.05) in the low BMD group than in the normal BMD group. IPW-adjusted regression analysis revealed that low BMD was independently associated with an adverse OS (hazard ratio, 1.42; 95% CI, 1.04–1.93; P=0.03), in addition to other factors such as tumor number, extrahepatic disease, preoperative carcinoembryonic antigen level (≥5 ng/mL), and right-sided primary tumor location. Conclusions Preoperative CT-measured low BMD can serve as a surrogate marker of adverse OS in CRLM patients undergoing liver resection. Prevention and early intervention for osteopenia/osteoporosis may be suggested for these patients.

Abstract
While pregnancy-related malignancies are quite rare, their incidence is increasing and thus affecting more and more women nowadays. Their management, however, with both chemotherapy and supportive agents remains quite challenging and it seems crucial to define the optimal treatment for this special population. Concerning supportive medication, it is clinically significant to determine whether commonly used agents, including Granulocyte Colony-Stimulating Factors, Erythropoiesis-stimulating agents, Bisphosphonates, Anticoagulation agents, Antiemetics and Glucocorticoids are indeed effective in ameliorating chemotherapy side effects. Meanwhile, it is of great importance that the administration of any of these agents is safe for both mother and fetus. This review aims to provide a précis of the current literature regarding both safety and efficacy of all categories of supportive medication during pregnancy.

Abstract
BACKGROUND Aromatase inhibitors (AIs) play an important role in the endocrine therapy of postmenopausal breast cancer patients, with a recent tendency to extend the duration of their use. However, AIs may increase the risk of osteoporotic bone fractures. This meta-analysis evaluated the risk of osteoporotic fractures of the hip, spine, and other locations in breast cancer patients using AIs. METHODS We performed a systematic search to identify randomized controlled clinical trials that investigated osteoporotic fractures in breast cancer patients on AI therapy. The main outcomes were the incidence and risk of osteoporotic fractures in general and of hip, vertebral, and non-vertebral fractures in AI users and controls. RESULTS The systematic review found a total of 30 randomized controlled trials including 117,974 participants. The meta-analysis showed a higher incidence of osteoporotic fracture in AI users: The crude risk ratio for all osteoporotic fractures was 1.35 (95% confidence interval [CI], 1.29-1.42; P < 0.001), for hip fractures 1.18 (95% CI, 1.02-1.35; P < 0.001), for vertebral fractures 1.84 (95% CI, 1.36-2.49; P < 0.001), and for non-vertebral fractures 1.18 (95% CI, 1.02-1.35; P < 0.001), respectively, compared to the controls. CONCLUSION Our meta-analysis suggested an increased risk of osteoporotic fractures for AI therapy in patients with breast cancer that was most expressed for vertebral fractures. Breast cancer patients on AIs need to be monitored for osteoporosis and osteoporotic fractures, and active prevention measures should be implemented.

Abstract
Background The fracture risk induced by anti-estrogen therapy in patients with breast cancer remains controversial. The aim of this study was to perform a meta-analysis and systematic review to evaluate the risk of osteoporotic fracture in patients with breast cancer. Methods A systematic search was performed to identify studies that included any osteoporotic fracture (hip fracture and vertebral fracture) in patients breast cancer. Main outcome measures were occurrence and risk of osteoporotic fractures including hip and vertebral fractures in patients and controls. Results A systematic search yielded a total of 4 studies that included osteoporotic fracture outcomes in patients with breast cancer. Meta-analysis showed a higher risk of osteoporotic fracture in patients with breast cancer. Analysis of these 4 studies involving a total of 127,722 (23,821 cases and 103,901 controls) patients showed that the incidence of osteoporotic fractures was higher in the breast cancer group than in the control group. The pooled estimate of crude relative risk for osteoporotic fracture was 1.35 (95% confidence interval, 1.29-1.42; P<0.001). Conclusions Although studies were limited by a small number, results suggested a possible association between anti-estrogen therapy and increased risk of osteoporotic fractures in patients with breast cancer.

Abstract
As a common degenerative disease, osteoporosis (OS) is characterized by reduced bone mass and microarchitectural deterioration of bone tissue. Both genetic and environmental factors are involved in OS development. To date, ~300 genes have been confirmed to be involved in the pathogenesis of OS, a large majority of which have been independently investigated. As OS is a polygenetic disease, a comprehensive analysis focusing on the biological functions and interactions of OS‑related genes would provide valuable information. In this study, OS related research deposited in PubMed was retrieved and genes related to OS were catalogued. Pathways with an enriched biological function for these genes were extracted, and the crosstalk between the enriched pathways was analyzed. A comprehensive network was constructed, and a minimal network was extracted using the Steiner minimal network algorithm. In this study, a total of 294 genes in were retrieved from PubMed. Biological processes found to be enriched included those related to bone metabolism and the immune system. In total, 58 pathways were enriched. Furthermore, the comprehensive network consisting of 3,943 nodes and 7,976 edges was constructed, among which 631 nodes and 2,581 edges contributed to the OS‑specific molecular network. In this network, in excess of 300 potential genes associated with OS and two modules were identified. Thus, this study provides a mechanistic insight into OS and suggests more than 300 potential OS‑related genes for future research.

Abstract
Bone health in prostate cancer patients represents a prerequisite for acceptable quality of life and optimal outcome of this disease. The major threat for bone health in prostate cancer displays cancer treatment induced bone loss as well as the development of bone metastases. In recent years, several new pharmaceuticals targeting bone metabolism such as denosumab or androgen pathway targeting drugs (abiraterone acetate and enzalutamide) have been approved for the treatment of progressive disease aiming to interrupt the vicious circle of bone metastasis and aberrant bone resorption. This development raised the awareness of the pivotal role of bone health in prostate cancer and introduced (symptomatic) skeletal related events as an important end point in recent clinical trials. Bone targeted drugs have become standard of care in patients with metastatic castration resistant prostate cancer, their role in metastatic hormone sensitive prostate cancer has been discussed controversely. In oligometastatic prostate cancer patients several promising approaches in metastasis directed therapy, including conventional surgery, stereotactic ablative radiation and image-guided single-fraction robotic stereotactic radiosurgery (CyberKnife®) were launched but are not in routine clinical use until now caused by sparse clinical evidence.
