RATIONALE:Diffuse idiopathic skeletal hyperostosis (DISH) is characterized by ossification along the anterolateral aspect of at least 4 contiguous vertebral bodies. A fracture involving the fused vertebra in patients with DISH often leads to severe instability and spinal cord injury. Spinal metastasis (Mets) and DISH can coexist in elderly patients and increase their risk of pathologic vertebral fractures. However, there are few reports on concomitant spinal Mets and DISH. PATIENT CONCERNS:A 78-year-old man who complained of gradual onset of paraparesis, sensory loss below the umbilicus, and incontinence (case 1) and a 63-year-old woman who complained of severe back pain and urinary incontinence (case 2). DIAGNOSIS:Two patients were diagnosed with spinal Mets and DISH. INTERVENTIONS:Decompression surgery was performed at the metastatic sites in case 1 whereas instrumentation surgery was performed in case 2 despite the fracture having a benign appearance with no associated neurologic symptoms. OUTCOMES:A vertebral fracture developed at the metastatic vertebra after decompression surgery in case 1. Severe instability of the surgical site in this case resulted in persistent paralysis even after subsequent revision surgery with instrumentation. In contrast, the clinical course was benign without any neurologic dysfunction at the 2-year follow-up in case 2. LESSONS:Instrumentation surgery should be performed in patients with DISH who develop spinal Mets even if there is no apparent instability.


基本原理: 弥漫性特发性骨骨质增生 (DISH) 的特征是沿着至少 4 个连续椎体的前外侧骨化。DISH患者累及融合椎的骨折常导致严重不稳定和脊髓损伤。脊柱转移 (Mets) 和DISH可并存于老年患者,增加其病理性椎体骨折的风险。然而,很少有关于伴随脊髓Mets和DISH的报道。 患者顾虑: 一位 78 岁的男性,主诉逐渐发病的下肢轻瘫、脐下感觉缺失、大小便失禁 (例 1) 一名 63 岁女性患者主诉严重背痛和尿失禁 (病例 2)。 诊断: 2 例患者确诊为脊柱Mets和DISH。 干预措施: 病例 1 在转移部位进行了减压手术,而病例 2 进行了器械手术,尽管骨折外观良性,无相关神经系统症状。 结局: 病例 1 减压手术后转移性椎体发生椎体骨折。本例手术部位严重不稳定,即使在随后使用器械翻修手术后,也会导致持续性瘫痪。相反,在病例 2 的 2 年随访中,临床过程是良性的,没有任何神经功能障碍。 教训: 即使没有明显的不稳定性,也应该对发生脊柱Mets的DISH患者进行器械手术。

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.
