Abstract
STUDY DESIGN Retrospective Cohort. OBJECTIVE Antiresorptive drugs are often given to minimize fracture risk for bone metastases, but data regarding optimal time or ability to reduce stereotactic body radiotherapy (SBRT)-induced fracture risk is limited. This study examines the association between antiresorptive use surrounding spinal SBRT and vertebral compression fracture (VCF) incidence to provide information regarding effectiveness and optimal timing of use. METHODS Patients treated with SBRT for spinal metastases at a single institution between 2009-2020 were included. Kaplan-Meier analysis was used to compare cumulative incidence of VCF for those taking antiresorptive drugs pre-SBRT, post-SBRT only, and none at all. Cox proportional hazards and Fine-Gray competing risk models were used to identify additional factors associated with VCF. RESULTS Of the 234 patients (410 vertebrae) analyzed, 49 (20.9%) were taking bisphosphonates alone, 42 (17.9%) were taking denosumab alone, and 25 (10.7%) were taking both. Kaplan-Meier analysis revealed a statistically significant lower VCF incidence for patients initiating antiresorptive drugs before SBRT compared to those taking none at all (4% vs 12% at 1 year post-SBRT, P = .045; and 4% vs 23% at 2 years, P = .008). On multivariate analysis, denosumab duration (HR: .87, P = .378) or dose (HR: 1.00, P = .644) as well as bisphosphonate duration (HR: .98, P= .739) or dose (HR: .99, P= .741) did not have statistical significance on VCF incidence. CONCLUSION Initiating antiresorptive agents before SBRT may reduce the risk of treatment-induced VCF. Antiresorptive drugs are underutilized in patients with spine metastases and may represent a useful intervention to minimize toxicity and improve long-term outcomes.

Abstract
The continuation of bone-modifying agents (BMAs) in patients with established medication-related osteonecrosis of the jaw (MRONJ) is a common concern among dentists and oncologists. There is little evidence supporting or refuting the continued use of BMAs or drug holidays and their impact on established MRONJ. This paper evaluates the outcome of continued BMAs use on the patient's MRONJ status. A retrospective review of 29 oncology patients undergoing active cancer care for either metastatic disease or multiple myeloma was conducted. Data on demographics, oncological status, BMA history and MRONJ status were collected. In total, 90% of patients were judged to have healed or stable MRONJ while continuing BMAs. Most patients (69%) continued the same BMA regime (three- or four-weekly) that they were on before developing MRONJ. The average number of BMAs doses received after an MRONJ diagnosis was 12 (range 1-48). Three patients (10.3%) were found to have MRONJ progression, with two patients developing new sites of necrosis. This real-world dataset suggests that the majority of MRONJ cases remain stable and will not worsen with the continuation of BMAs.

Abstract
Bone metastases are a significant source of morbidity and mortality for patients with breast and prostate cancer. In this review, we discuss key practical themes regarding the use of bone-targeted agents (btas) such as bisphosphonates and denosumab for managing bony metastatic disease. The btas both delay the onset and reduce the incidence of skeletal-related events (sres), defined as any or all of a need for radiation therapy or surgery to bone, pathologic fracture, spinal cord compression, or hypercalcemia of malignancy. They have more modest benefits for pain and other quality-of-life measures. Regardless of the benefits of btas, it should always be remembered that the palliative management of metastatic bone disease is multimodal and multidisciplinary. The collaboration of all disciplines is essential for optimal patient care. Special consideration is given to these key questions: ■ What are btas, and what is their efficacy?■ What are their common toxicities?■ When should they be initiated?■ How do we choose the appropriate bta?■ What is the appropriate dose, schedule, and duration of btas?

Abstract
The aim of this randomized, controlled animal exploratory trial was to investigate the influence of local application of aminobisphosphonate pamidronate during the socket preservation procedure. Mandibular premolars were extracted in five Göttingen minipigs. Two animals underwent socket preservation using BEGO OSS (n = 8 sockets) and three animals using BEGO OSS + Pamifos (15 mg) (n = 12 sockets). After jaw impression, cast models (baseline, eight weeks postoperative) were digitized using an inLab X5 scanner (Dentsply Sirona) and the generated STL data were superimposed and analyzed with GOM Inspect 2018 (GOM, Braunschweig). After 16 weeks, the lower jaws were prepared and examined using standard histological methods. In the test group (BEGO OSS + pamidronate), buccooral dimensional loss was significantly lower, both vestibulary (−0.80 ± 0.57 mm vs. −1.92 ± 0.63 mm; p = 0.00298) and lingually (−1.36 ± 0.58 mm vs. −2.56 ± 0.65 mm; p = 0.00104) compared with the control group (BEGO OSS). The test group showed a significant difference between vestibular and lingual dimensional loss (p = 0.04036). Histology showed cortical and cancellous bone in the alveolar sockets without signs of local inflammation. Adjuvant application of pamidronate during socket preservation reduces alveolar dimensional loss significantly. Further investigations with regard to dose–response relationships, volume effects, side effects, and a verification of the suitability in combination with other bone substitute materials (BSMs) are necessary.

Abstract
BACKGROUND Bisphosphonates are specific inhibitors of osteoclastic activity and are used in the treatment of patients with multiple myeloma (MM). While bisphosphonates are shown to be effective in reducing vertebral fractures and pain, their role in improving overall survival (OS) remains unclear. This is an update of a Cochrane review first published in 2002 and previously updated in 2010 and 2012. OBJECTIVES To assess the evidence related to benefits and harms associated with use of various types of bisphosphonates (aminobisphosphonates versus non-aminobisphosphonates) in the management of patients with MM. Our primary objective was to determine whether adding bisphosphonates to standard therapy in MM improves OS and progression-free survival (PFS), and decreases skeletal-related morbidity. Our secondary objectives were to determine the effects of bisphosphonates on pain, quality of life, incidence of hypercalcemia, incidence of bisphosphonate-related gastrointestinal toxicities, osteonecrosis of jaw (ONJ) and hypocalcemia. SEARCH METHODS We searched MEDLINE, Embase (September 2011 to July 2017) and the CENTRAL (2017, Issue 7) to identify all randomized controlled trial (RCT) in MM up to July 2017 using a combination of text and MeSH terms. SELECTION CRITERIA Any randomized controlled trial (RCT) comparing bisphosphonates versus placebo/no treatment/bisphosphonates and observational studies or case reports examining bisphosphonate-related ONJ in patients with MM were eligible for inclusion. DATA COLLECTION AND ANALYSIS Two review authors extracted the data. Data were pooled and reported as hazard ratio (HR) or risk ratio (RR) using a random-effects model. We used meta-regression to explore statistical heterogeneity. Network meta-analysis using Bayesian approach was conducted. MAIN RESULTS In this update, we included four new studies (601 participants), resulting in a total of 24 included studies.Twenty RCTs compared bisphosphonates with either placebo or no treatment and four RCTs involved another bisphosphonate as a comparator. The 24 included RCTs enrolled 7293 participants. Pooled results showed that there was moderate-quality evidence of a reduction in mortality with on OS from 41% to 31%, but the confidence interval is consistent with a larger reduction and small increase in mortality compared with placebo or no treatment (HR 0.90, 95% CI 0.76 to 1.07; 14 studies; 2706 participants). There was substantial heterogeneity among the included RCTs (I2 = 65%) for OS. To explain this heterogeneity we performed a meta-regression assessing the relationship between bisphosphonate potency and improvement in OS, which found an OS benefit with zoledronate but limited evidence of an effect on PFS. This provided a further rationale for performing a network meta-analyses of the various types of bisphosphonates that were not compared head-to-head in RCTs. Results from network meta-analyses showed evidence of a benefit for OS with zoledronate compared with etidronate (HR 0.56, 95% CI 0.29 to 0.87) and placebo (HR 0.67, 95% CI 0.46 to 0.91). However, there was no evidence for a difference between zoledronate and other bisphosphonates.The effect of bisphosphonates on disease progression (PFS) is uncertain. Based on the HR of 0.75 (95% CI 0.57 to 1.00; seven studies; 908 participants), 47% participants would experience disease progression without treatment compared with between 30% and 47% with bisphosphonates (low-quality evidence). There is probably a similar risk of non-vertebral fractures between treatment groups (RR 1.03, 95% CI 0.68 to 1.56; six studies; 1389 participants; moderate-quality evidence). Pooled analysis demonstrated evidence for a difference favoring bisphosphonates compared with placebo or no treatment on prevention of pathological vertebral fractures (RR 0.74, 95% CI 0.62 to 0.89; seven studies; 1116 participants; moderate-quality evidence) and skeletal-related events (SREs) (RR 0.74, 95% CI 0.63 to 0.88; 10 studies; 2141 participants; moderate-quality evidence). The evidence for less pain with bisphosphonates was of very low quality (RR 0.75, 95% CI 0.60 to 0.95; eight studies; 1281 participants).Bisphosphonates may increase ONJ compared with placebo but the confidence interval is very wide (RR 4.61, 95% CI 0.99 to 21.35; P = 0.05; six studies; 1284 participants; low-quality evidence). The results from the network meta-analysis did not show any evidence for a difference in the incidence of ONJ (eight RCTs, 3746 participants) between bisphosphonates. Data from nine observational studies (1400 participants) reported an incidence of 5% to 51% with combination of pamidronate and zoledronate, 3% to 11% with zoledronate alone, and 0% to 18% with pamidronate alone.The pooled results showed no evidence for a difference in increase in frequency of gastrointestinal symptoms with the use of bisphosphonates compared with placebo or no treatment (RR 1.23, 95% CI 0.95 to 1.59; seven studies; 1829 participants; low-quality evidence).The pooled results showed no evidence for a difference in increase in frequency of hypocalcemia with the use of bisphosphonates compared with placebo or no treatment (RR 2.19, 95% CI 0.49 to 9.74; three studies; 1090 participants; low-quality evidence). The results from network meta-analysis did not show any evidence for differences in the incidence of hypocalcemia, renal dysfunction and gastrointestinal toxicity between the bisphosphonates used. AUTHORS' CONCLUSIONS Use of bisphosphonates in participants with MM reduces pathological vertebral fractures, SREs and pain. Bisphosphonates were associated with an increased risk of developing ONJ. For every 1000 participants treated with bisphosphonates, about one patient will suffer from the ONJ. We found no evidence of superiority of any specific aminobisphosphonate (zoledronate, pamidronate or ibandronate) or non-aminobisphosphonate (etidronate or clodronate) for any outcome. However, zoledronate was found to be better than placebo and first-generation bisposphonate (etidronate) in pooled direct and indirect analyses for improving OS and other outcomes such as vertebral fractures. Direct head-to-head trials of the second-generation bisphosphonates are needed to settle the issue if zoledronate is truly the most efficacious bisphosphonate currently used in practice.

Osteolytica: An automated image analysis software package that rapidly measures cancer-induced osteolytic lesions in in vivo models with greater reproducibility compared to other commonly used methods. Bone 2016; 83:9-16. [PMID: 26456145 PMCID: PMC4720217 DOI: 10.1016/j.bone.2015.10.004] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2015] [Revised: 09/22/2015] [Accepted: 10/06/2015] [Indexed: 12/02/2022]
Abstract
Methods currently used to analyse osteolytic lesions caused by malignancies such as multiple myeloma and metastatic breast cancer vary from basic 2-D X-ray analysis to 2-D images of micro-CT datasets analysed with non-specialised image software such as ImageJ. However, these methods have significant limitations. They do not capture 3-D data, they are time-consuming and they often suffer from inter-user variability. We therefore sought to develop a rapid and reproducible method to analyse 3-D osteolytic lesions in mice with cancer-induced bone disease. To this end, we have developed Osteolytica, an image analysis software method featuring an easy to use, step-by-step interface to measure lytic bone lesions. Osteolytica utilises novel graphics card acceleration (parallel computing) and 3-D rendering to provide rapid reconstruction and analysis of osteolytic lesions. To evaluate the use of Osteolytica we analysed tibial micro-CT datasets from murine models of cancer-induced bone disease and compared the results to those obtained using a standard ImageJ analysis method. Firstly, to assess inter-user variability we deployed four independent researchers to analyse tibial datasets from the U266-NSG murine model of myeloma. Using ImageJ, inter-user variability between the bones was substantial (±19.6%), in contrast to using Osteolytica, which demonstrated minimal variability (±0.5%). Secondly, tibial datasets from U266-bearing NSG mice or BALB/c mice injected with the metastatic breast cancer cell line 4T1 were compared to tibial datasets from aged and sex-matched non-tumour control mice. Analyses by both Osteolytica and ImageJ showed significant increases in bone lesion area in tumour-bearing mice compared to control mice. These results confirm that Osteolytica performs as well as the current 2-D ImageJ osteolytic lesion analysis method. However, Osteolytica is advantageous in that it analyses over the entirety of the bone volume (as opposed to selected 2-D images), it is a more rapid method and it has less user variability.

Abstract
BACKGROUND Pain is a common symptom in patients with multiple myeloma (MM). Many patients are dependent on analgesics and in particular opioids, but there is limited information on the impact of these drugs and their side effects on health-related quality of life (HRQoL). METHOD In a cross-sectional study, semi-structured interviews were performed in 21 patients attending the hospital with symptomatic MM on pain medications. HRQoL was measured using items 29 and 30 of the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30. RESULTS Patients were able to recall a median of two (range 0-4) analgesics. They spontaneously identified a median of two (range 1-5) side effects attributable to their analgesic medications. Patients' assessment of HRQoL based on the EORTC QLQ-C30 questions 29/30 was mean 48.3 (95 % CI; 38.7-57.9) out of 100. Patients' assessment of their HRQoL in the hypothetical situation, in which they would not experience any side effects from analgesics, was significantly higher: 62.6 (53.5-71.7) (t test, p = 0.001). CONCLUSION This study provides, for the first time, evidence that side effects of analgesics are common in symptomatic MM and may result in a statistically and clinically significant reduction of self-reported HRQoL.

Abstract
BACKGROUND Randomized controlled trials (RCTs) have reported different results when using zoledronate to treat skeletal-related events (SREs) and bone pain in patients with metastatic bone disease (MBD), and few have looked at the risks and benefits of long-term use of the drug. This meta-analysis aimed to investigate the efficacy and safety of zoledronate to treat MBD in the short and long-term. METHODS PubMed, EMBASE, and the Cochrane Library were searched to identify RCTs evaluating zoledronate for MBD. Relative risks (RRs) and 95% confidence intervals (CIs) were calculated. RESULTS Twelve RCTs involving 4,450 patients were included in the meta-analysis. Zoledronate decreased the risk of developing SREs compared with placebo (RR 0.75, 95% CI 0.69 to 0.81, P < 0.001). Zoledronate consistently reduced the brief pain inventory (BPI) below baseline compared with placebo at 3, 12, and 24 months. In addition, the likelihood of experiencing a bone pain event was significantly lower in the zoledronate group than in the placebo group (RR 0.83, 95% CI 0.76 to 0.89, P < 0.001). While the two groups did not differ significantly in the incidence of nausea(RR = 1.07, 95% CI 0.96 to 1.19, P = 0.250), emesis (RR 0.94, 95% CI 0.81 to 1.09, P = 0.420), or adverse renal events (RR 1.41, 95% CI 0.94 to 2.11, P = 0.09), the zoledronate group showed a significantly higher relative risk of pyrexia (RR 1.43, 95% CI 1.20 to 1.70, P < 0.001), fatigue (RR 1.26, 95% CI 1.10 to 1.43, P < 0.001), and anemia (RR 1.33, 95% CI 1.14 to 1.55, P < 0.001). CONCLUSION Compared to placebo, zoledronate significantly reduced the incidence of bone pain and SREs in patients with MBD for periods as long as 24 months. In addition, zoledronate is generally well tolerated over this long period.

Abstract
PURPOSE Bisphosphonates are known to prevent skeletal-related events (SREs) in advanced breast cancer, prostate cancer, and multiple myeloma. This systematic review assessed the efficacy of bisphosphonates in preventing SREs, controlling pain, and overall survival in patients with bone metastases from lung cancer. METHODS We searched MEDLINE, EMBASE, Web of Science, and the Cochrane Library databases through November 10, 2011 for controlled trials that included lung cancer patients with bone metastases treated with bisphosphonates. Two reviewers independently extracted data on pain control, survival, and SREs and evaluated the quality of each study. Meta-analyses were performed when there were two or more trials with similar outcomes. RESULTS Twelve trials met our inclusion criteria and included 1,767 patients. Studies were placebo-controlled, or had compared bisphosphonates with other modalities (chemotherapy, radiation therapy, or radioisotope therapy), or had used different bisphosphonates as active controls. Randomized controlled trials did not report adequate descriptions of randomization procedures, allocation concealment, and blinding, resulting in low-quality scores. Patients treated with zoledronic acid + chemotherapy had fewer SREs than those receiving chemotherapy alone (relative risk (RR) 0.81, 95 % confidence interval (CI) 0.67-0.97). Pain control improved when a bisphosphonate was added to another treatment modality (chemotherapy or radiation; RR 1.18, 95 %CI 1.0-1.4). Bisphosphonate therapy improved survival compared to controls, but the difference failed to reach statistical significance (mean of 72 days, 95 %CI -8.9 to 152.9). CONCLUSIONS Treatment with bisphosphonates reduced SREs, improved pain control, and showed a trend to increased survival. Bisphosphonates should be used in the treatment of patients with lung cancer and bone metastases.

Abstract
BACKGROUND Bisphosphonates are specific inhibitors of osteoclastic activity and used in the treatment of patients with multiple myeloma (MM). While bisphosphonates are shown to be effective in reducing vertebral fractures and pain, their role in improving overall survival (OS) remains unclear. This is an update of a Cochrane review first published in 2002 and previously updated in 2010. OBJECTIVES To assess the evidence related to benefits and harms associated with use of various types of bisphosphonates (aminobisphosphonates versus nonamino bisphosphonates) in the management of patients with MM. Our primary objective was to determine whether adding bisphosphonates to standard therapy in MM improves OS and progression-free survival (PFS), and decreases skeletal-related morbidity. Our secondary objectives were to determine the effects of bisphosphonates on pain, quality of life, incidence of hypercalcemia, incidence of bisphosphonate-related gastrointestinal toxicities, osteonecrosis of jaw and hypocalcemia. SEARCH METHODS We searched MEDLINE, LILACS, EMBASE (December 2009 to October 2011) and the Cochrane Controlled Trials Register (all years, latest Issue September 2011) to identify all randomized trials in MM up to October 2011 using a combination of text and MeSH terms. We also handsearched relevant meeting proceedings (December 2009 to October 2011). SELECTION CRITERIA Any randomized controlled trial (RCT) assessing the role of bisphosphonates and observational studies or case reports examining bisphosphonate-related osteonecrosis of the jaw in patients with MM were eligible for inclusion. DATA COLLECTION AND ANALYSIS Two review authors extracted the data. Data were pooled and reported as hazard ratio (HR) or risk ratio (RR) under a random-effects model. Statistical heterogeneity was explored using metaregression. MAIN RESULTS In this update, we included 2 studies (2464 patients) that were not part of our last Cochrane review published in 2010. In this review we included 16 RCTs comparing bisphosphonates with either placebo or no treatment and 4 RCTs with a different bisphosphonate as a comparator. The 20 included RCTs enrolled 6692 patients. Overall methodological quality of reporting was moderate. Thirty per cent (6/20) of trials reported the method of generating the randomization sequence. Forty per cent (8/20) of trials had adequate allocation concealment. Withdrawals and dropouts were described in 60% (12/20) of trials. Pooled results showed no direct effect of bisphosphonates on OS compared with placebo or no treatment (HR 0.96, 95% CI 0.82 to 1.13; P = 0.64). However, there was a statistically significant heterogeneity among the included RCTs (I(2) = 55%, P = 0.01) for OS. To explain this heterogeneity we performed a metaregression assessing the relationship between bisphosphonate potency and improvement in OS, which found indicating an OS benefit with zoledronate (P = 0.058). This provided a further rationale for performing network meta-analyses of the various types of bisphosphonates that were not compared head to head in RCTs. Results from network meta-analyses showed superior OS with zoledronate compared with etidronate (HR 0.43, 95% CI 0.16 to 0.86) and placebo (HR 0.61, 95% CI 0.28 to 0.98). However, there was no difference between zoledronate and other bisphosphonates. Pooled analysis did not demonstrate a beneficial effect of bisphosphonates compared with placebo or no treatment in improving PFS (HR 0.70, 95% CI 0.41 to 1.19; P = 0.18) There was no heterogeneity among trials reporting PFS estimates (I(2) = 35%, P = 0.20).Pooled analysis demonstrated a beneficial effect of bisphosphonates compared with placebo or no treatment on prevention of pathological vertebral fractures (RR 0.74, 95% CI 0.62 to 0.89; I(2) = 7%), skeletal-related events (SRE) (RR 0.80, 95% CI 0.72 to 0.89; I(2) = 2%) and amelioration of pain (RR 0.75, 95% CI 0.60 to 0.95; I(2) = 63%). The network meta-analysis did not show any difference in the incidence of osteonecrosis of the jaw (5 RCTs, 3198 patients) between bisphosphonates. Rates of osteonecrosis of the jaw in observational studies (9 studies, 1400 patients) ranged from 0% to 51%. The pooled results (6 RCTs, 1689 patients) showed no statistically significant increase in frequency of gastrointestinal symptoms with the use of bisphosphonates compared with placebo or no treatment (RR 1.23, 95% CI 0.95 to 1.60; P = 0.11).The pooled results (3 RCTs, 1002 patients) showed no statistically significant increase in frequency of hypocalcemia with the use of bisphosphonates compared with placebo or no treatment (RR 2.19, 95% CI 0.49 to 9.74). The network meta-analysis did not show any differences in the incidence of hypocalcemia, renal dysfunction and gastrointestinal toxicity between the bisphosphonates used. AUTHORS' CONCLUSIONS Use of bisphosphonates in patients with MM reduces pathological vertebral fractures, SREs and pain. Assuming a baseline risk of 20% to 50% for vertebral fracture without treatment, between 8 and 20 MM patients should be treated to prevent vertebral fracture(s) in one patient. Assuming a baseline risk of 31% to 76% for pain amelioration without treatment, between 5 and 13 MM patients should be treated to reduce pain in one patient. With a baseline risk of 35% to 86% for SREs without treatment, between 6 and 15 MM patients should be treated to prevent SRE(s) in one patient. Overall, there were no significant adverse effects associated with the administration of bisphosphonates identified in the included RCTs. We found no evidence of superiority of any specific aminobisphosphonate (zoledronate, pamidronate or ibandronate) or nonaminobisphosphonate (etidronate or clodronate) for any outcome. However, zoledronate appears to be superior to placebo and etidronate in improving OS.

Abstract
PURPOSE The aim of the study was to report and discuss the preliminary data obtained in a homogeneous series of 50 patients affected by multiple myeloma treated with bisphosphonates. METHODS Patients were followed for a minimum of 1 year. Main orthopaedic data were recorded. Visual Analogue Score and QLQ-C30 and MY 20 were used to assess the quality of life. RESULTS Statistical analysis showed less lytic lesions in the group with zoledronate therapy and stable primary disease compared with a greater number of lesions in the non-treated group. Results regarding VAS score and QLQ-C30 and MY were statistically better in the first group than in the second. CONCLUSIONS Our results confirm the efficacy of zoledronate in ensuring an acceptable quality of life restraining the aggressiveness of the myeloma on bone tissue, especially in spine although further prospective studies have to be conducted to determine its correct use in myeloma patients.

Abstract
Breast cancer often metastasizes to bone causing osteolytic bone resorption which releases active TGFβ. Because TGFβ favors progression of breast cancer metastasis to bone, we hypothesized that treatment using anti-TGFβ antibody may reduce tumor burden and rescue tumor-associated bone loss in metastatic breast cancer. In this study we have tested the efficacy of an anti-TGFβ antibody 1D11 preventing breast cancer bone metastasis. We have used two preclinical breast cancer bone metastasis models, in which either human breast cancer cells or murine mammary tumor cells were injected in host mice via left cardiac ventricle. Using several in vivo, in vitro and ex vivo assays, we have demonstrated that anti-TGFβ antibody treatment have significantly reduced tumor burden in the bone along with a statistically significant threefold reduction in osteolytic lesion number and tenfold reduction in osteolytic lesion area. A decrease in osteoclast numbers (p = 0.027) in vivo and osteoclastogenesis ex vivo were also observed. Most importantly, in tumor-bearing mice, anti-TGFβ treatment resulted in a twofold increase in bone volume (p<0.01). In addition, treatment with anti-TGFβ antibody increased the mineral-to-collagen ratio in vivo, a reflection of improved tissue level properties. Moreover, anti-TGFβ antibody directly increased mineralized matrix formation in calverial osteoblast (p = 0.005), suggesting a direct beneficial role of anti-TGFβ antibody treatment on osteoblasts. Data presented here demonstrate that anti-TGFβ treatment may offer a novel therapeutic option for tumor-induced bone disease and has the dual potential for simultaneously decreasing tumor burden and rescue bone loss in breast cancer to bone metastases. This approach of intervention has the potential to reduce skeletal related events (SREs) in breast cancer survivors.

Abstract
BACKGROUND This study retrospectively compared the risks of skeletal-related events (SREs) and zoledronic acid (ZOL) treatment discontinuation associated with early vs. delayed ZOL therapy for patients with symptomatic multiple myeloma (MM). PATIENTS AND METHODS Data were collected from a physician-administered medical chart review among US patients with a confirmed diagnosis of symptomatic MM treated after 01/01/2002. Early and delayed ZOL therapy were defined, respectively, as initiating ZOL ≤ 60 days (N = 126) vs. > 60 days (N = 186) after the first symptomatic MM diagnosis. Kaplan-Meier analysis with a log-rank test was performed to compare the risk of SREs between the cohorts. Cox proportional hazard modeling compared the risk of SREs associated with early vs. delayed ZOL treatment, controlling for demographic factors, stage of MM, bone health status, and presence of major comorbidities at diagnosis. Time to ZOL discontinuation was evaluated using the Kaplan-Meier method, following patients from the date of ZOL initiation. RESULTS Time to the first SRE was significantly longer for patients who received early treatment with ZOL (P = .005). At 2 years after diagnosis, the SRE-free rate was 74.6% vs. 56.5% in the early vs. delayed treatment group, respectively. Early ZOL therapy was associated with a significantly lower risk of any SRE (hazard rate [HR] = .625 vs. delayed ZOL therapy; P = .029). At 2 years from ZOL therapy initiation, rates of ZOL discontinuation were 9.6% vs. 16.4% among patients with early vs. delayed therapy, respectively (P < .05). CONCLUSION Early treatment with ZOL was associated with significantly reduced risks of SREs and with better treatment persistence compared with delayed treatment.

Abstract
Advanced multiple myeloma is typically accompanied by osteolytic bone lesions resulting from heightened osteolytic activity of osteoclasts and decreased rates of osteogenesis by osteoblasts. Therefore, patients with myeloma bone disease are at increased risk for skeletal-related events (SREs) such as pathologic fracture, the need for radiotherapy or surgery to bone, spinal cord compression, and hypercalcemia of malignancy. Each of these can reduce patients' functional independence, quality of life, and survival. Radiotherapy and surgery are often used to palliate bone pain and to stabilize, repair, or prevent bone fractures. Bisphosphonates (BPs) may reduce the risk of SREs. In particular, clodronate, pamidronate, and zoledronic acid (ZOL) have demonstrated efficacy for delaying the onset of potentially life-threatening SREs. Overall, BPs have a well established tolerability profile. The introduction of BPs for multiple myeloma was practice-changing, and patients now experience far fewer serious fractures and hypercalcemia of malignancy. Ongoing studies will help further refine and optimize the timing and duration of BP therapy in patients with myeloma bone disease.

Abstract
BACKGROUND Bisphosphonate-associated osteonecrosis of the jaws (BP-ONJ) is an adverse effect of bisphosphonate treatment with varying reported incidence rates. METHODS In two neighboring German cities, prevalence and additional factors of the development of BP-ONJ in multiple myeloma patients with bisphosphonates therapy were recorded using a retrospective (RS) and cross-sectional study (CSS) design. For the RS, all patients treated from Jan. 2000--Feb. 2006 were contacted by letter. In the CSS, all patients treated from Oct. 2006--Mar. 2008 had a physical and dental examination. Additionally, a literature review was conducted to evaluate all articles reporting on BP-ONJ prevalence. PubMed search terms were: bisphosphonat, diphosphonate, osteonecrosis, prevalence and incidence. RESULTS In the RS, data from 81 of 161 patients could be obtained; four patients (4.9%) developed BP-ONJ. In the CSS, 16 of 78 patients (20.5%) developed BP-ONJ. All patients with BP-ONJ had received zoledronate; 12 of these had had additional bisphosphonates. All except one had an additional trigger factor (tooth extraction [n = 14], dental surgical procedure [n = 2], sharp mylohyoid ridge [n = 3]). CONCLUSION The prevalence of BP-ONJ may have been underestimated to date. The oral examination of all patients in this CSS might explain the higher prevalence, since even early asymptomatic stages of BP-ONJ and previously unnoticed symptomatic BP-ONJ were recorded. Since nearly all patients with BP-ONJ had an additional trigger factor, oral hygiene and dental care might help to reduce BP-ONJ incidence.

Abstract
BACKGROUND Bisphosphonates are specific inhibitors of osteoclastic activity and are currently used as supportive therapy for multiple myeloma (MM). However, the exact clinical role of bisphosphonates in MM remains unclear. OBJECTIVES This update of the first review published in 2002. We have also analyzed observational studies targeting osteonecrosis of jaw (ONJ). SEARCH STRATEGY We searched the literature using the methods outlined in the previous review. We also searched observational studies or case reports examining ONJ. SELECTION CRITERIA We selected RCTs with a parallel design related to the use of bisphosphonate in myeloma. We also selected observational studies or case reports examining bisphosphonates related to ONJ. DATA COLLECTION AND ANALYSIS We have reported pooled data using either hazard ratio or risk ratio and, when appropriate, as absolute risk reduction and the number needed to treat to prevent or to cause a pathological event. We have assessed statistical heterogeneity and reported I(2) statistic. MAIN RESULTS This review includes 17 trials with 1520 patients analyzed in bisphosphonates groups, and 1490 analyzed in control groups. In comparison with placebo/no treatment, the pooled analysis demonstrated the beneficial effect of bisphosphonates on prevention of pathological vertebral fractures (RR= 0.74 (95% CI: 0.62 to 0.89), P = 0.001), total skeletal related events (SREs) (RR= 0.80 (95% CI: 0.72 to 0.89), P < 0.0001) and on amelioration of pain (RR = 0.75 (95% CI: 0.60 to 0.95), P = 0.01). We found no significant effect of bisphosphonates on overall survival (OS), progression-free survival (PFS), hypercalcemia or on the reduction of non-vertebral fractures. The indirect meta-analyses did not find the superiority of any particular type of bisphosphonate over others. Only two RCTs reported ONJ. The identified observational studies suggested that ONJ may be a common event (range: 0% to 51%). AUTHORS' CONCLUSIONS Adding bisphosphonates to the treatment of MM reduces pathological vertebral fractures, SREs and pain but not mortality. Assuming the baseline risk of 20% to 50% for vertebral fracture without treatment, we estimate that between eight and 20 MM patients should be treated to prevent vertebral fracture(s) in one patient. Assuming the baseline risk of 31% to 76% for pain amelioration without treatment, we estimate that between five to 13 MM patients should be treated to reduce pain in one patient. Also, with the baseline risk of 35% to 86% for SREs without treatment, we estimate that between six and 15 MM patients should be treated to prevent SRE(s) in one patient.

Abstract
Microbial biofilms have been observed and described in bone specimens of patients with bisphosphonate (BP)-associated osteonecrosis of the jaw (BONJ) and investigators are more recently suggesting that this condition essentially represents an osteomyelitis of the jaw clinically, with greater susceptibility in some patients on BP therapy. This article explains the role of microbial biofilms in BONJ and also discusses associated factors in the disease pathogenesis, which include BP effects on bone remodeling, anti-angiogenesis, matrix necrosis, microcracks, soft tissue toxicity, and inflammation and wound healing. Recent findings suggest a key role for microbial biofilms in the pathogenesis of BONJ; this has important therapeutic implications because biofilm organisms represent a clinical target for prevention and treatment efforts aimed at reducing the significant morbidity and costs associated with this condition.

Abstract
PURPOSE To evaluate the changes of bone marrow lesions on pelvic and spinal MR in patients with multiple myeloma after high-dose chemotherapy and autologous peripheral blood stem cell transplant. PATIENTS AND METHODS Pelvic and spinal MR examinations were obtained at presentation (myeloma diagnosis) and 1 year after transplant in 20 patients that were part of a group of 39 patients enrolled in a prospective study. The type of marrow replacement (classified in stages with stage 0: normal; stage 1: salt and pepper; stage 2: focal infiltration; stage 3: diffuse infiltration), the number and size of marrow lesions and the number of vertebral compression fractures were recorded. We have compared the findings prior to and following transplant, with correlation to the response to treatment and the use of biphosphonates. RESULTS The type of marrow replacement was improved following transplant in 65% of patients (not statistically significant). The number and size of nodules > 20 mm showed significant reduction (p = 0.0224 and p = 0.0237 respectively). Lesions on MR improved in 50% of patients with good response and 75% of patients with poor response to treatment. Patients receiving biphosphonates showed more vertebral compression fractures. CONCLUSION The evolution of marrow replacing lesions on MR is discordant compared to the biological and clinical response to treatment. Pelvic and spinal MR evaluation at the time of diagnosis does not appear to be a good predictive factor of response to treatment. Biphosphonates do not appear to prevent new vertebral compression fractures. Pelvic and spinal MR provides interesting data in the follow-up of patients with myeloma following autologous transplant, especially in the local evolution of marrow replacing lesions, but our results do not justify its use in routine clinical practice.

Abstract
BACKGROUND Complications from skeletal-related events (SREs) constitute a challenge in the care of patients with metastatic bone disease (MBD) that originated from any type of malignancy. OBJECTIVE The purpose of this article was to compare the efficacy of clodronate, pamidronate, and zoledronate with that of placebo in reducing morbidity and overall mortality in cancer patients with MBD. METHODS MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were searched (from inception to January 2009) to retrieve randomized clinical trials that evaluated the bisphosphonates of interest. The search included articles published in English, French, Italian, Portugese, and Spanish. Patients with a definite (ie, biopsy-proven) diagnosis of MBD were included in the analysis. We extracted and combined data from studies that reported the number of patients with SREs and mortality data. A random-effects, meta-analytic model was applied in all calculations. The Jadad scale was used to assess the quality of study reporting. RESULTS The literature search identified 62 potential full-text studies; 44 of these studies were excluded and 18 were evaluated. The mean (SD) quality of reporting of the included studies was 57.8% (22.6%), or 2.89/5 (1.1/5). Each of the 3 drugs was found to be more effective than placebo in preventing all SREs in cancer patients with MBD. The relative risk of developing SREs was 0.70 (95% CI, 0.61-0.81; N = 1211) for zoledronate, 0.81 (95% CI, 0.73-0.91; N = 2251) for pamidronate, and 0.87 (95% CI, 0.75-1.00; N = 681) for clodronate. However, no clear advantage of one drug over the others was observed (CIs overlapped substantially). None of the bisphosphonates was more beneficial than placebo in reducing the number of deaths in the course of the trials (P = NS). CONCLUSION Clodronate, pamidronate, and zoled-ronate were associated with reductions in morbidity in cancer patients with MBD with regard to preventing SREs, but were not associated with a reduction in overall mortality.

Abstract
Although the quality of clinical practice guidelines has improved over the last decade, current guideline systems have limitations that reduce their validity and limit their acceptance. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) working group, a worldwide collaboration of guideline developers, methodologists, and clinicians, has constructed a system for developing guidelines that addresses these shortcomings. The system includes a transparent and rigorous methodology for rating the quality of evidence, an explicit balancing of benefits and harms of healthcare interventions, an explicit acknowledgement of the values and preferences that underlie the recommendations, and whether the intervention represents a wise use of resources. These four elements determine whether a recommendation is strong or weak. A guideline panel offers strong recommendations when virtually all informed patients would choose the same management strategy. Weak recommendations imply that choices will differ across the range of patient values and preferences. The GRADE system has been tested in multiple practice settings and for a large spectrum of questions, refined and re-evaluated to ensure that it captures the complex issues involved in evidence assessment and grading recommendations while maintaining simplicity and practicality. Many guideline organizations and medical societies have endorsed the system and adopted it for their guideline processes.

Abstract
Treatment of multiple myeloma, a B-cell cancer, is usually palliative, however, as a result of intensive clinical research there are numerous new treatment options available today. The present review summarizes non-transplant treatment options for multiple myeloma on the basis of available publications. Treatment with new substances, such as immunomodulatory agents, farnesyl transferase inhibitors and apoptosis stimulators, and their mechanisms of action are discussed. In addition to this systematic review of the available evidence on multiple myeloma therapy we have also summarized current recommendations from national and international organizations on aspects of the treatment of multiple myeloma. This should enable readers to see different points of view at a glance and, hopefully, will provide a basis for translation of the available evidence into the best possible therapy.

Abstract
The introduction of bisphosphonates has increased in the last decade following their indication for metastatic bone diseases, osteoporosis, hypercalcaemia of malignancy and Paget's disease. Although bisphosphonates have been used clinically for more than three decades there have been no documented long-term complications of their effects on the jaws until recently, where there is now growing evidence of the influence of bisphosphonates on osteonecrosis of the jaws. The aim of this paper is to report a case of this newly described complication, to review this phenomenon, including the clinical implications and to reiterate current clinical guidelines for management of patients in which bisphosphonate therapy is indicated. To the best of our knowledge this is the first reported case of bisphosphonate-induced necrosis of the jaw in South Africa.

Abstract
A paraprotein is a monoclonal immunoglobulin or light chain present in the blood or urine; it is produced by a clonal population of mature B cells, most commonly plasma cells. In individuals aged >50 years the incidence of a paraprotein is 3.2%. Plasma cell disorders can be considered as a spectrum of conditions ranging from monoclonal gammopathy of undetermined significance (MGUS), through asymptomatic, to symptomatic myeloma. MGUS is defined by a low level of paraprotein <30 g/l, bone marrow plasma cells <10% and the absence of myeloma related organ or tissue damage (predominantly renal, skeletal or bone marrow impairment.) MGUS requires no therapy and the overall risk of progression to myeloma is 1% per year. Myeloma remains incurable with a median survival of 3-4 years; autologous stem cell transplant can prolong survival, if appropriate. Thalidomide in combination with dexamethasone has an emerging role in the treatment of myeloma.

Abstract
Maintaining bone health in men who have advanced prostate cancer is an important goal of therapy. Low bone mass is prevalent in men who have prostate cancer, and long-term androgen deprivation therapy causes additional significant decreases in bone mineral density. The adverse effects of the disease and current treatment modalities on bone health are further compounded when patients develop bone metastases,which cause clinically significant skeletal morbidity. Treatment with bone-directed therapies, including intravenous bisphosphonates, radio-nuclides, and endothelin-1 antagonists, can provide palliative and therapeutic benefits for patients who have established bone metastases, and treatment with intravenous bisphosphonates may prevent the development of bone metastases.

Abstract
In people with cancer, pain often occurs from the malignancy, from procedures done to diagnose, stage, and treat the malignancy, and from the toxicities of therapy used in treating the cancer. Of people with cancer, 75% complain of some sort of pain. Determining whether the pain is from tissue damage or nerve structures will guide therapy. Assessment of the severity of the pain by location, oncological type, as well as psychosocial and environmental factors are necessary to understand and treat the pain that accompanies cancer. Medical interventions include non-opioid analgesics, opioids, and multiple different combinations of medications. Adjuvant medication like anticonvulsants and steroids are being used frequently to help people feel more comfortable.

Abstract
Bone disease is a major feature of multiple myeloma. Myeloma-induced bone destruction is the result of an increased activity of osteoclasts, which is not accompanied by a comparable increase of osteoblast function. Recent studies have revealed that new molecules such as the receptor activator of nuclear factor-kappa B (RANK), its ligand (RANKL), osteoprotegerin (OPG), and macrophage inflammatory protein-1alpha are implicated in osteoclast activation and differentiation, while proteins such as dickkopf-1 inhibit osteoblastic bone formation. These new molecules seem to interfere not only with the biology of myeloma bone destruction but also with tumour growth and survival, creating novel targets for the development of new antimyeloma treatment. Currently, bisphosphonates play a major role in the management of myeloma bone disease. Clodronate, pamidronate and zoledronic acid are the most effective bisphosphonates in symptomatic myeloma patients. Biochemical markers of bone remodeling have been used in an attempt to identify patients more likely to benefit from early treatment with bisphosphonates. Furthermore, using microarray techniques, myeloma patients may be subdivided into molecular subgroups with certain clinical characteristics, such as propensity for lytic lesions that may need early prophylactic treatment. Recent phase I studies with recombinant OPG and monoclonal antibodies to RANKL appear promising.

Abstract
Long-term bisphosphonate therapy has been shown to offer clinical benefit in the management of multiple myeloma. This study sought to explore the feasibility and potential advantages of monthly home-based intravenous infusions of pamidronate in patients with multiple myeloma. In a prospective crossover, multicentre trial, 37 patients were randomly allocated to receive 3 months of treatment with pamidronate given in the home followed by 3 months of treatment with pamidronate given in hospital or vice versa. Results from a patient preference questionnaire indicated most patients preferred treatment at home. Quality-of-life measurement was undertaken using the EORTC QLQ-C30 questionnaire. The results indicated a small, generally consistent, although not statistically significant, trend in favour of home care treatment. Extra nursing specialist time was required for home therapy. Home therapy with pamidronate in patients with multiple myeloma appeared feasible and safe and was preferred by patients in this study.

Abstract
OBJECTIVE To review the evidence for the use of bisphosphonates to reduce skeletal morbidity in cancer patients with bone metastases. DATA SOURCES Electronic databases, scanning reference lists, and consultation with experts and pharmaceutical companies. Foreign language papers were included. STUDY SELECTION Included trials were randomised controlled trials of patients with malignant disease and bone metastases who were treated with oral or intravenous bisphosphonate compared with another bisphosphonate, placebo, or standard care. All trials measured at least one outcome of skeletal morbidity. RESULTS 95 articles were identified; 30 studies fulfilled inclusion criteria. In studies that lasted > or = 6 months, compared with placebo bisphosphonates significantly reduced the odds ratio for fractures (vertebral 0.69, 95% confidence interval 0.57 to 0.84, P < 0.0001; non-vertebral 0.65, 0.54 to 0.79, P < 0.0001; combined 0.65, 0.55 to 0.78, P < 0.0001), radiotherapy (0.67, 0.57 to 0.79, P < 0.0001), and hypercalcaemia (0.54, 0.36 to 0.81, P = 0.003) but not for orthopaedic surgery (0.70, 0.46 to 1.05, P = 0.086) or spinal cord compression (0.71, 0.47 to 1.08, P = 0.113). The reduction in orthopaedic surgery was significant in studies that lasted over a year (0.59, 0.39 to 0.88, P = 0.009). Use of bisphosphonates significantly increased time to first skeletal related event but did not increase survival. Subanalyses showed that most evidence supports use of intravenous aminobisphosphonates. CONCLUSIONS In people with metastatic bone disease bisphosphonates significantly decrease skeletal morbidity, except for spinal cord compression and increased time to first skeletal related event. Treatment should start when bone metastases are diagnosed and continue until it is no longer clinically relevant.

Abstract
Multiple myeloma (MM) is characterized by infiltration of bone marrow with a clone of neoplastic plasma cells. Impaired hematopoiesis and reduced production of functional immunoglobulins, as well as the induction of pathognomonic osteolytic lesions primarily contribute to the morbidity of patients with MM. Conventional chemotherapy is the treatment of choice for older patients, whereas those under 60 years benefit significantly from high-dose therapy followed by stem-cell rescue. The use of tandem transplantation, developed to further escalate the conditioning dose, has achieved additional improvement in survival. Interferon-alpha and glucocorticoids are effective as maintenance measures in MM but remain controversial because of their associated high costs and considerable toxicity. The resurrection of an old drug, thalidomide, for the therapy of MM and the development of potent immunomodulatory derivatives are highly promising new treatments that target MM cell-host interactions and the bone-marrow microenvironment, as well as the myeloma cell itself. The importance of the use of bisphosphonates for the prevention or amelioration of skeletal complications and hypercalcemia is well established. New generations of bisphosphonates show potent antitumor activity, again emphasising the importance of targeting the microenvironment of the plasma-cell clone.

Abstract
Although amino-bisphosphonates (N-BPs) induce apoptosis of myeloma cells in vitro, most in-vivo studies fail to demonstrate a corresponding antitumour effect. This discrepancy might reflect the development of resistance to the antitumour effects of N-BP in myeloma cells when they are exposed to N-BP for a prolonged time. To test this hypothesis, two N-BP-sensitive human myeloma cell lines were continuously exposed to increasing concentrations of the N-BP alendronate for 6 weeks. During this treatment period, 10 out of 10 sublines developed reduced apoptotic and antiproliferative responses to alendronate treatment. This de novo alendronate resistance was accompanied by resistance to another N-BP (zoledronate) but not to an inhibitor of 3-hydroxy-3-methylglutaryl CoA reductase or Fas ligand. Importantly, N-BP-resistant myeloma cells also remained sensitive to conventional myeloma chemotherapeutics (melphalan, doxorubicin and vincristine). Further analysis of the N-BP-resistant cells revealed an increased activity of the N-BP-specific target enzyme farnesyl pyrophosphate synthase, without upregulation of its gene transcription. Our results suggest that continuous exposure of myeloma cells to alendronate leads to the development of N-BP resistance. This is associated with an increased activity of farnesyl pyrophosphate synthase and does not evolve from defective apoptotic pathways. Importantly, the antitumour effects of conventional myeloma chemotherapeutics are preserved in the N-BP-resistant myeloma cells.
