STUDY DESIGN:Meta-analysis. OBJECTIVE:To understand the benefits and limitations of surgical management and adjuvant therapies for patients presenting with neurological deficits from vertebral hemangiomas (VH). SUMMARY OF BACKGROUND DATA:VH is the most common benign spine tumor but rarely causes symptoms. Patients with back pain alone are treated with conservative management (kyphoplasty and radiation therapy), while those with neurological deficits require complex multi-modal treatment plans. METHODS:A PubMed literature search for "symptomatic vertebral hemangioma with spinal cord compression" identified 47 articles. From these articles and their references, 19 observational studies on patients who underwent surgery for VH met inclusion criteria. Meta-analyses were performed comparing outcomes of the surgical and adjuvant therapies using Stata13 software. For those with insufficient data for meta-analyses, descriptive analyses of variables were completed. RESULTS:One hundred ninety seven surgical cases of VH with neurologic deficits were identified. Surgery provided a complete remission of symptoms in 84% of patients, however 18% of patients had recurrence of hemangioma. Adjuvant interventions included radiation, embolization, and kyphoplasty. Radiation therapy (XRT) was associated with a lower recurrence rate and an increase in minor transient adverse effects. Preoperative embolization performed in 98 patients was associated with improved symptoms, reduced complications, lower recurrence rate, less blood loss, and higher incidence of pathologic vertebral fractures. Meta-analyses did not yield statistically significant results, likely due to the heterogeneity amongst the studies and small sample sizes, but the results compiled together provide insight on potential benefits of preoperative embolization for symptomatic relief and reduced risk of recurrence with XRT that deserves further study. CONCLUSION:For patients with neurologic deficits from spinal cord or nerve root compression, surgery provides improvement in symptoms. Recurrence of VH and symptoms refractory to surgery can be further reduced by adjuvant therapies such as embolization, kyphoplasty, and radiation with some unique risks to each therapy. LEVEL OF EVIDENCE:2.


研究设计: 荟萃分析。 目的: 了解椎体血管瘤 (VH) 神经功能缺损患者手术治疗和辅助治疗的益处和局限性。 背景资料概述: VH是最常见的良性脊柱肿瘤,但很少引起症状。单纯背痛患者采用保守治疗 (椎体后凸成形术和放射治疗),而神经功能缺损的患者需要复杂的多模态治疗计划。 方法: PubMed文献检索 “症状性椎体血管瘤伴脊髓压迫”,共检索出 47 篇文献。从这些文章及其参考文献中,19 项针对接受VH手术患者的观察性研究符合纳入标准。使用Stata13 软件进行Meta分析,比较手术和辅助治疗的结果。对于荟萃分析数据不足的人,完成了变量的描述性分析。 结果: 确定了 117 例伴有神经功能缺损的VH手术病例。手术使 84% 的患者症状完全缓解,但 18% 的患者血管瘤复发。辅助干预措施包括放射、栓塞和椎体后凸成形术。放射治疗 (XRT) 与较低的复发率和轻微的一过性不良反应增加相关。术前栓塞治疗 98 例,症状改善,并发症减少,复发率低,出血量少,病理性骨折发生率高。荟萃分析没有产生统计学显著的结果,可能是由于研究之间的异质性和样本量小,但汇总的结果提供了术前栓塞用于缓解症状和降低XRT复发风险的潜在益处,值得进一步研究。 结论: 对于脊髓或root压迫引起的神经功能缺损患者,手术可改善症状。栓塞、椎体后凸成形术和放疗等辅助治疗可以进一步减少VH的复发和手术难治性症状,每种治疗都有一些独特的风险。 证据级别: 2。

METHODS:OBJECTIVE:Large inoperable sacral chordomas show unsatisfactory local control rates even when treated with high dose proton therapy (PT). The aim of this study is assessing feasibility and reporting early results of patients treated with PT and concomitant hyperthermia (HT). METHODS: :Patients had histologically proven unresectable sacral chordomas and received 70 Gy (relative biological effectiveness) in 2.5 Gy fractions with concomitant weekly HT. Toxicity was assessed according to CTCAE_v4. A volumetric tumor response analysis was performed. RESULTS: :Five patients were treated with the combined approach. Median baseline tumor volume was 735 cc (range, 369-1142). All patients completed PT and received a median of 5 HT sessions (range, 2-6). Median follow-up was 18 months (range, 9-26). The volumetric analysis showed an objective response of all tumors (median shrinkage 46%; range, 9-72). All patients experienced acute Grade 2-3 local pain. One patient presented with a late Grade 3 iliac fracture. CONCLUSION:Combining PT and HT in large inoperable sacral chordomas is feasible and causes acceptable toxicity. Volumetric analysis shows promising early results, warranting confirmation in the framework of a prospective trial. ADVANCES IN KNOWLEDGE: :This is an encouraging first report of the feasibility and early results of concomitant HT and PT in treating inoperable sacral chordoma.

METHODS:BACKGROUND:National guidelines recommend screening and treatment for cancer-related bone disease and continued monitoring of bone-modifying agents. It is unclear whether a standardized screening tool is utilized to identify eligible patients and ensure appropriate supportive care is implemented. The purpose of this study was to evaluate current prescribing practices and optimize management of bone-modifying agents. METHODS:A retrospective chart review was performed to identify patients who received hormone deprivation therapy or had bone metastases through Hematology/Oncology or Urology clinics from 1 November 2016 to 31 October 2017. The primary endpoints of this study were the incidence of completed baseline dual-energy X-ray absorptiometry (DEXA) scan for patients on hormone deprivation therapy and percent of patients started on a bone-modifying agent for the prevention of skeletal-related events secondary to bone metastasis. Secondary endpoints included percent of patients with dental examinations prior to initiation, adequate calcium and vitamin D supplementation, incidence of osteonecrosis of the jaw or flu-like symptoms and education, and percent of bisphosphonate doses appropriately adjusted based on renal function. RESULTS:A total of 375 patients were assessed for baseline DEXA scans and bone-modifying therapy. Of the 226 patients on hormone deprivation therapy, 111 (49%) patients were appropriately screened with a DEXA scan prior to initiation of hormone deprivation therapy. Among the 149 patients with bone metastases, only 94 (63.1%) patients were started on a bone-modifying agent. CONCLUSIONS:Opportunities have been identified to optimize management of patients with cancer-related bone disease. Implementation of standardized tools may increase the rate of appropriate screening and initiation of bone-modifying therapy when warranted.

METHODS:PURPOSE:Low skeletal muscle mass has been associated with poor prognosis in patients with advanced lung cancer. However, little is known about the relationship between skeletal muscle mass and overall survival in patients with bone metastases from lung cancer. The objective of the present study was to evaluate the prognostic value of low trunk muscle mass in predicting overall survival in these patients. METHODS:The data from 198 patients who were diagnosed with bone metastases from lung cancer from April 2009 to May 2017 were retrospectively reviewed. The areas of the psoas and paravertebral muscles were measured at the level of the third lumbar vertebra on computed tomography scans taken at the time nearest to the diagnosis of bone metastasis. Muscle area was evaluated for male and female cohorts separately using different cutoff points. Cox proportional hazards analysis was performed to evaluate the factors independently associated with overall survival. RESULTS:The overall survival of patients in the lowest quartile for psoas muscle area or paravertebral muscle area was significantly shorter than that of patients above the 25th percentile for muscle area (p < 0.001). Multivariate analyses showed that paravertebral muscle mass (hazard ratio, 1.73; 95% confidence interval, 1.17-2.56; p = 0.006), epidermal growth factor receptor-targeted therapy, and performance status were independent prognostic factors. CONCLUSIONS:Low paravertebral muscle mass was associated with shorter survival, independently of known prognostic factors.
