The landscape of MM has changed dramatically in recent years. Several new and more effective treatments have been introduced that not only makes patients live longer but also brings them into a deeper remission. This makes the potential total exposure of bone protective treatment much higher but perhaps also less needed. New and more precise imagining techniques have been introduced making detection of bone disease more sensitive, and the introduction of SLiM-CRAB criteria have changed the parameters used in old clinical trials investigating treatment of MM bone disease. New data have also emerged investigating the effect of the RANKL inhibitor denosumab compared to zoledronic acid (ZOL). Randomized trials have investigated longer treatment durations, which becomes more relevant as patients now live longer.
In addition in this review, data regarding interval between individual treatment, impact of remission status, new data in relation to rebound after discontinuation and of denosumab, as well as the rational for drug holidays before dental procedures will also be discussed.

Ewing sarcoma (EwS) is the second most prevalent pediatric bone malignancy, characterized by its aggressive behavior and unfavorable prognosis. The tumor microenvironment (TME) of EwS is shaped by immunosuppressive components, including myeloid-derived suppressor cells, tumor-associated macrophages, and immune checkpoint molecules such as PD-1/PD-L1 and HLA-G. These elements impair anti-tumor immune responses by modulating the function of tumor-infiltrating immune cells, such as regulatory T cells (Tregs), CD8+ T cells, and natural killer cells. Chemokines, including CXCL9 and CXCL12, and cytokines, such as transforming growth factor-beta and interleukin-10, further contribute to immune suppression and promote metastatic dissemination. Recent advances in immunotherapy have highlighted the therapeutic potential of modulating immune cells and signaling pathways to enhance anti-tumor immunity. This review provides a comprehensive analysis of the complex immune landscape within the EwS TME, focusing on the mechanistic roles of key immune components and their potential as therapeutic targets. Understanding these interactions could pave the way for innovative treatment strategies to improve clinical outcomes in patients with EwS.

Background
Patients with bone metastases in the femur (BMf) may experience pathological fractures requiring surgery with cemented endoprostheses (EPR). At cementation and prosthesis insertion, patients are at risk of experiencing hypoxia, hypotension, cardiac failure and potentially death, known as bone cement implantation syndrome (BCIS). We aimed to 1) investigate the incidence and grade of BCIS in patients with BMf treated with cemented EPR, and 2) examine if the incidence or extent of BCIS has decreased after a change of a combined anesthesiologic and surgical protocol.
Methods
We retrospectively assessed patients with BMf operated with cemented EPR in two periods 2017 – 2018 (early cohort) and 2019 – 2020 (late cohort) and stratified before and after the intervention.
Results
Comparing the early and late cohorts, 26/86 (32 %) vs. 30/80 (35 %) experienced BCIS, but mild BCIS (grade 0 + 1) was seen in 79 % vs. 86 %, and severe BCIS (grade 2 + 3) in 21 % vs. 14 %. In the late cohort the per-operative use of vasopressors was higher (86 % vs. 59 %, p < 0.001), we found fewer pulmonary embolisms (PE) (p = 0.024), and a trend toward a reduced length of stay (LOS). 30-day survival was lower for patients with grade 0 + 1 compared to grade 2 + 3 (p = 0.03).
Conclusions
BCIS occurs in more than 1/3 of patients operated for BMf with cemented EPR. An increased multidisciplinary focus on BCIS may reduce the complications of BCIS, such as PE and LOS.

Background
There is currently no consensus on the optimal surgical treatment for patients with spinal metastases. Investigating regional variations in surgical management could provide valuable insights to optimize care and refine surgical practices globally.
Objective
To investigate differences in patient populations, surgical management, and perioperative outcomes among patients who underwent surgery for spinal metastases in either Boston (United States) or Utrecht (Netherlands).
Methods
727 patients surgically treated for spinal metastases in Boston (n=539) and Utrecht (n=188) between 2018–2022 were included. Data on patient characteristics, surgical management, perioperative outcomes, and survival were collected. The Mann-Whitney U test was used for continuous data, and Fisher’s exact test for categorical data.
Results
In Boston, a higher percentage of patients had three or more spinal metastases (68% vs 59%; p=0.006) and brain metastases (16% vs 4.3%; p<0.001) at the time of surgery compared with Utrecht. Vertebrectomy/corpectomy with stabilization was performed in 54% of patients in Boston versus none in Utrecht (p<0.001), whereas percutaneous stabilization was performed in 1.3% of patients in Boston versus 39% in Utrecht (p<0.001). In Utrecht, patients received postoperative radiotherapy more frequently (70% vs 54%; p<0.001) and earlier (17 days [IQR:12–24] vs 29 days [IQR:23–39]; p<0.001). Postoperative neurological outcome, complications, reoperation rates, and survival did not differ between the two cohorts (all p>0.05).
Conclusions
Differences in patient populations and surgical management exist between tertiary hospitals on separate continents. Further research is needed to determine the optimal extent and timing of surgery to improve quality of life for patients with spinal metastases.
背景目前对于脊柱转移患者的最佳手术治疗方法尚无共识。调查手术管理的区域差异可以为优化护理和改进全球手术实践提供有价值的见解。目的研究美国波士顿和荷兰乌得勒支接受脊柱转移手术的患者群体、手术处理和围手术期预后的差异。方法纳入2018-2022年间在波士顿(n=539)和乌得勒支(n=188)接受脊柱转移手术治疗的727例患者。收集了患者特征、手术处理、围手术期结局和生存率的数据。连续数据采用Mann-Whitney U检验,分类数据采用Fisher精确检验。结果在波士顿,有三个或三个以上脊柱转移的患者比例更高(68% vs 59%;P =0.006)和脑转移(16% vs 4.3%;p<0.001),与乌得勒支相比。波士顿54%的患者进行了椎体切除术/椎体切除术并进行了稳定,而乌得勒支没有(p<0.001),而波士顿1.3%的患者进行了经皮稳定,而乌得勒支39% (p<0.001)。在乌得勒支,患者术后接受放疗的频率更高(70% vs 54%;p<0.001)和更早(17天[IQR: 12-24] vs 29天[IQR: 23-39];术中,0.001)。术后神经预后、并发症、再手术率和生存率在两个队列之间没有差异(均p < 0.05)。结论各大洲三级医院在患者人群和手术管理方面存在差异。需要进一步的研究来确定手术的最佳范围和时机,以改善脊柱转移患者的生活质量。

Despite the fact that chemotherapy for bone sarcomas (e.g. Ewing sarcoma, osteosarcoma) has well-reported toxicities and that surgical intervention is frequently life altering, follow-up care to monitor for late and long-term effects beyond that of oncological surveillance in former patients is variable. Anecdotal evidence suggests that inconsistent follow-up means some former bone sarcoma patients are left to cope with post-treatment late and long-term effects with limited support. Here, we performed a scoping review to provide a more empirical identification of the knowledge gaps and to provide an overview of the peer reviewed academic literature reporting the late and long-term effects of treatment for bone sarcoma. JBI Scoping Review Network guidelines for charting, analysis and data extraction were followed. Literature searches were conducted in Medline (Ovid), Cochrane CENTRAL, EMBASE (Ovid), CINAHL, PsycINFO, Proquest and Web of Science (Clarivate Analytics) from March 2024 to September 2024. Paper titles and abstracts were screened by two independent reviewers followed by full text analysis by the lead researcher. Seventy-four peer reviewed articles were included in the analysis. Most studies were of a retrospective study design, some up to 20 years of follow-up and included chemotherapy, surgery and sometimes radiotherapy as the treatment modality. Our analysis identified secondary malignancies, cardio- and nephrotoxicity, lower bone mineral density and microarchitectural deterioration, cancer related fatigue and motor neuropathies as the major physical late and long-term effects requiring dedicated follow-up. In some cases, follow-up may need to span decades, especially given the increasing population of former patients. Our results form the evidence-based foundations for future work that might include late and long-term effect follow-up service mapping exercises and expanded clinical recommendations.
尽管骨肉瘤(如尤文氏肉瘤、骨原性肉瘤)的化疗有很好的毒性报道,而且手术干预经常改变患者的生活,但在既往患者中监测肿瘤监测之外的晚期和长期影响的随访护理是可变的。轶事证据表明,不一致的随访意味着一些前骨肉瘤患者只能在有限的支持下应对治疗后的晚期和长期影响。在这里,我们进行了一项范围综述,以提供对知识差距的更多经验鉴定,并提供同行评议的学术文献综述,报告骨肉瘤治疗的晚期和长期影响。遵循JBI范围审查网络的制图、分析和数据提取指南。文献检索于2024年3月至2024年9月在Medline (Ovid)、Cochrane CENTRAL、EMBASE (Ovid)、CINAHL、PsycINFO、Proquest和Web of Science (Clarivate Analytics)进行。论文标题和摘要由两位独立审稿人筛选,然后由首席研究员进行全文分析。74篇同行评议文章被纳入分析。大多数研究是回顾性研究设计,有些长达20年的随访,包括化疗,手术,有时放疗作为治疗方式。我们的分析确定继发性恶性肿瘤、心脏和肾毒性、低骨密度和微结构恶化、癌症相关的疲劳和运动神经病变是主要的晚期和长期生理影响,需要专门的随访。在某些情况下,随访可能需要跨越几十年,特别是考虑到以前的患者人数不断增加。我们的研究结果为未来的工作奠定了证据基础,这些工作可能包括后期和长期效果的后续服务测绘工作和扩大的临床建议。

Objective
Prostate cancer (PCa) often metastasizes to the bone, posing a significant clinical challenge. This study aims to develop a bone metastasis-related risk model for PCa.
Methods
Bone metastasis-related genes (BMRGs) were identified through a combination of differential gene expression analysis and WGCNA using GSE32269 and GSE77930 datasets. Consensus clustering analysis was employed to determine the significance of these genes in molecular subtyping of PCa. LASSO-Cox regression analysis was utilized to construct the bone metastasis-related prognostic gene signature (BMRPS). The predictive performance of BMRPS was assessed using ROC curves, Kaplan-Meier survival curves, and a predictive nomogram. The immune landscape heterogeneity of subgroups was analyzed using CIBERSORT, ESTIMATE, and xCell algorithms. Drug sensitivity and molecular docking analysis were performed to identify drugs associated with BMRPS.
Results
Forty-four BMRGs associated with the prognosis of PCa were identified. Consensus clustering revealed the pivotal role of these genes in stratifying PCa into three distinct prognostic clusters. The BMRPS, consisting of 14 BMRGs, demonstrated excellent predictive accuracy for prognosis and served as an independent prognostic factor in PCa. BMRPS effectively predicted the overall survival of bone metastatic PCa and differentiated bone metastasis from other metastatic types. BMRPS showed a close correlation with the immune landscape and immunotherapeutic response biomarkers. Additionally, BMRPS was associated with anti-androgen resistance, and AZD8186 was identified as a potential BMRPS-related drug that holds promise for personalized treatment in PCa.
Conclusion
BMRPS facilitates the prediction of prognosis and resistance to anti-androgens in PCa. It also offers insights into the molecular mechanisms of bone metastasis and aids in drug selection for the treatment of PCa.

Background
Osteosarcoma is the most common primary malignant bone tumor in pediatric and adolescent patients. Although pulmonary metastasis is a key driver of prognosis, the role of IPNs in risk stratification remains inadequately defined.
Objective
This study aims to assess the incidence, progression, and prognostic significance of IPNs in pediatric and adolescent osteosarcoma patients, providing insights for clinical staging and treatment strategy development.
Methods
We retrospectively analyzed clinical data from 126 osteosarcoma patients aged 20 years or younger who were treated at Henan Cancer Hospital between January 2012 and January 2022. Pre-treatment thin-slice computed tomography (CT) scans of lung were used to categorize patients into three groups: no IPN (n = 100), solitary IPN (n = 16), and multiple IPNs (n = 10). Baseline characteristics, primary tumor parameters, treatment modalities, and follow-up data were collected. Univariate and multivariate analyses were conducted to assess risk factors and survival outcomes.
Results
The overall incidence of IPNs was 20.6 %, with multiple IPNs accounting for 38.5 % of the IPN-positive cases. A significantly higher proportion of patients in the IPN-positive group had bone involvement exceeding one-third of the total affected bone compared to the no-IPN group (57.7 % vs. 34.0 %, p = 0.016). While univariate analysis suggested a potential association between tumor diameter > 8 cm and IPN occurrence (odds ratio [OR] = 2.08, 95 % confidence interval [CI]: 0.83–5.21, p = 0.120), this was not statistically significant in multivariate analysis (OR = 3.61, p = 0.283). Kaplan–Meier survival analysis revealed that the 3-year metastasis-free survival (MFS) and overall survival (OS) rates in the IPN-positive group were significantly lower than those in the no-IPN group (MFS: 57.7 % vs. 64.0 %, p = 0.03; OS: 65.4 % vs. 76.0 %, p = 0.04). Further subgroup analysis indicated that while solitary IPN cases had survival outcomes comparable to those without IPNs, multiple IPN cases exhibited a markedly reduced 5-year OS (30.0 % vs. 69.0 %, p = 0.045). Cox regression analysis demonstrated that multiple IPNs increased the risk of death by 2.87-fold (hazard ratio [HR] = 2.87, p = 0.020).
Conclusion
Indeterminate Pulmonary Nodules are relatively common in pediatric osteosarcoma patients.

背景:骨肉瘤是儿童和青少年患者中最常见的原发性恶性骨肿瘤。虽然肺转移是预后的关键驱动因素,但ipn在风险分层中的作用仍未充分界定。目的探讨小儿和青少年骨肉瘤患者IPNs的发病率、进展及预后意义,为临床分期和治疗策略制定提供依据。方法回顾性分析2012年1月至2022年1月在河南省肿瘤医院收治的126例20岁及以下骨肉瘤患者的临床资料。使用治疗前肺部薄层计算机断层扫描(CT)将患者分为三组:无IPN (n = 100),单发IPN (n = 16)和多发IPN (n = 10)。收集基线特征、原发肿瘤参数、治疗方式和随访数据。进行单因素和多因素分析以评估危险因素和生存结果。结果ipn总发病率为20.6%,多发ipn占ipn阳性病例的38.5%。与无ipn组相比,ipn阳性组患者骨受累超过总受影响骨的三分之一的比例明显更高(57.7%比34.0%,p = 0.016)。单因素分析显示肿瘤直径与gt之间存在潜在关联;8 cm与IPN的发生(优势比[OR] = 2.08, 95%可信区间[CI]: 0.83-5.21, p = 0.120),多因素分析中差异无统计学意义(OR = 3.61, p = 0.283)。Kaplan-Meier生存分析显示,ipn阳性组的3年无转移生存率(MFS)和总生存率(OS)明显低于无ipn组(MFS: 57.7% vs. 64.0%, p = 0.03;OS: 65.4% vs. 76.0%, p = 0.04)。进一步的亚组分析表明,虽然单发IPN患者的生存结果与无IPN患者相当,但多发性IPN患者的5年OS明显降低(30.0% vs 69.0%, p = 0.045)。Cox回归分析显示,多重IPNs使死亡风险增加2.87倍(危险比[HR] = 2.87, p = 0.020)。结论不确定肺结节在小儿骨肉瘤中较为常见。特别是,多发ipn与更高的肿瘤负担和转移潜力增加密切相关,可作为预后不良的独立指标。这些发现强调了术前IPN评估和风险分层在指导个体化治疗策略中的重要性。

Purpose
the purpose of this study was to describe the baseline characteristics, presenting phenotype and treatment interventions for patients diagnosed with multiple osteochondromas who presented with severe pain symptoms.
Methods
a retrospective single-centre cohort study was conducted at a Rare Skeletal Disorders Department. Pain symptomatology was measured at the first visit, pain level was reported, varying from 0, absence of pain to 10, maximum pain. Baseline characteristics, pathology phenotype using IOR classification and treatments performed/ongoing as medical, surgical and conservative therapies were collected.
Results
a total of 152 patients were enrolled, with a median pain score of 0 and the 25th and 75th percentiles of 0 and 4, respectively. A percentage of 25.7 % (95 % CI of 19.3–33.3) presented at the first visit with moderate/severe pain. Multiple logistic regression confirmed that age was the only factor to be significantly associated with moderate/severe pain and IOR classification was not able to provide a description of the pathology that was associated with a major pain score.
Conclusion
from the early stages of multiple osteochondromas diagnosis, pain symptoms must be carefully assessed. An increase in age is associated with a worsening of pain; IOR classification of the multiple osteochondromas phenotype does not currently allow an association between the various classes and pain. A re-evaluation of the classification in this light could be an important new element for clinical practice.

Surgery for spinal metastases is almost always palliative and part of a multidisciplinary approach that has determined a significant increase of life expectancy in the last decade; thus, an improvement in health-related quality of life (HRQOL) is the main goal of the treatment of spinal metastases. We report here the results of a prospective study conducted with the aim of evaluating the impact of spinal surgery on HRQOL, measured by Patient-Reported Outcomes Measures (PROMs). We analyzed clinical outcomes (ambulatory status, performance status, pain, neurological status) and HRQOL scores (VAS, EQ5D, SF36) during the follow-up period and focused on factors that could affect quality of life, considering both psychological and physical issues.
Methods
169 patients (96 males, 73 females) with vertebral metastases who underwent surgery at a tertiary referral center were consecutively enrolled from August 2018 to October 2022. Clinical and surgical data were prospectively collected, and PROMs (VAS, EQ-5D and SF-36) were registered before surgery and during follow up.
Results
The overall survival was 22 months, and a 61 % survival rate was registered at 1 year follow-up. We observed a significant improvement in walking ability, general performance status, pain and HRQOL after surgery, which was maintained during the follow up. Multivariate analysis identified three independent variables, capable of influencing the trend of HRQOL after surgery: the presence of pathological fracture, the preoperative neurological status and the local recurrence of disease.
Discussion
This study confirms the effectiveness of surgery for spinal metastases in improving patients’ performance status and demonstrates an overall improvement in HRQOL, which is maintained over time.

Background
This study aims to explore the prognostic value of myosteatosis in multiple myeloma (MM) and to analyze the factors influencing myosteatosis.
Methods
A retrospective analysis was conducted on 182 patients treated for MM at our institution from 2009 to 2020 who underwent MRI examinations. The fatty infiltration rate (FIR) of the erector spinae and multifidus muscles at the L3 level was measured to assess the degree of myosteatosis. Patients were grouped based on fracture presence and median FIR, and group differences were compared, with P < 0.05 considered statistically significant. Survival and fractures were used as prognostic indicators, and regression analysis was performed to determine the impact of FIR on these outcomes in MM patients. The factors influencing FIR were analyzed, and the relationship between myosteatosis and MM prognosis was further analyzed within its sensitive subgroups. Finally, a nomogram based on FIR was established and validated.
Results
Significant differences were observed between the fracture and non-fracture groups in lactate dehydrogenase, serum phosphorus, visual analogue scale, oswestry disability index and FIR (P < 0.05). When patients were grouped based on the median FIR (28.89 %), there were significant differences in age, sex, body mass index (BMI), red blood cell (RBC) count, hemoglobin, hematocrit, albumin, visual analogue scale, oswestry disability index, and fracture incidence (P < 0.05). Univariate COX regression analysis indicated that myosteatosis had no significant impact on survival prognosis in MM patients (HR = 0.999, P = 0.852), with a log-rank test P value of 0.11 when grouped by the cut-off FIR value of 33.67 %. Multivariate logistic regression indicated that FIR is an independent predictor of fractures (OR = 1.054, P = 0.000). Multivariate linear regression revealed that age, sex, RBC count, and BMI are independent factors influencing FIR (P < 0.05). When not grouped, FIR’s prediction of fractures showed no significant interaction with age, sex, RBC count, or BMI (P for interaction > 0.05). In subgroups with BMI ≥ 25 kg/m2 or RBC count > 3.68 × 10^12/L, FIR lost its predictive significance for fractures. The FIR nomogram model had a C-index of 0.777, and the calibration curve, decision curve analysis, and clinical impact curve all validated its effectiveness.
Conclusions
Myosteatosis characterized by FIR is not a reliable predictor of survival in MM patients but is effective in predicting fractures and is closely related to back pain and functional impairment. FIR is significantly associated with age, sex, RBC count, and BMI.
