BACKGROUND AND OBJECTIVES:We aimed to identify the overall survival (OS), surgical complications, survival of reconstruction, and functional outcome of patients who underwent extra-articular resection of the shoulder joint for primary bone sarcomas. The OS and local recurrence rates in patients who underwent an amputation were also evaluated for comparison. METHODS:Thirty-two patients treated between 1988 and 2017 were studied. The tumours were located in the humerus in 22 (69%) and scapula in 10 patients (31%). The resection types were Malawer type IV in 6 (19%), type V in 21 (66%), and type VI in 5 patients (15%). Reconstruction was performed with endoprosthesis in 23 patients (72%) while excision arthroplasty with the suspension of the humerus to the clavicle was performed in 9 patients (28%). Surgical margins were wide in 16, marginal in 8, intralesional in 3, and not available in 5 patients. During the study period, 40 patients underwent a forequarter amputation and 11 patients underwent a shoulder disarticulation. RESULTS:The 5-year OS for patients who underwent extra-articular resection of the shoulder joint was 42% which was not statistically different compared with that of patients who underwent amputation (5-year OS = 30%; P = .091). The 5-year survival of the reconstruction was 94%, similar for endoprosthesis and excision arthroplasty. Local recurrence and complications developed in 6 (19%) and 10 patients (31%), respectively. Failures of the reconstruction requiring revision surgery occurred in two patients (6%). Limb salvage was achieved in 30 patients (94%). The median Musculoskeletal Tumour Society functional score was 61% (interquartile range, 57%-70%) and was similar in the endoprosthesis and excision arthroplasty group. CONCLUSIONS:Extra-articular resection of the shoulder joint for bone sarcomas is an effective limb-salvage method. However, local recurrence remains a principal concern.


背景和目的: 我们旨在确定重建的总生存率 (OS) 、手术并发症、和接受肩关节外切除术治疗原发性骨肉瘤患者的功能结局。对接受截肢手术的患者的OS和局部复发率也进行了评估比较。 方法: 对 1988 年至 2017 年间收治的 32 例患者进行研究。肿瘤位于肱骨 22 例 (69%),肩胛骨 10 例 (31%)。切除类型Malawer ⅳ 型 6 例 (19%),ⅴ 型 21 例 (66%),ⅵ 型 5 例 (15%)。23 例 (72%) 采用内假体重建,9 例 (28%) 采用肱骨悬吊至锁骨的切除关节成形术。手术切缘宽 16 例,边缘 8 例,病灶内 3 例,5 例患者不可用。在研究期间,40 例患者接受了前肢截肢术,11 例患者接受了肩关节离断术。 结果: 接受肩关节外切除的患者的 5 年OS为 42%,与接受截肢的患者相比无统计学差异 (5 年OS = 30%; P =.091)。重建的 5 年生存率为 94%,与内假体和切除关节成形术相似。局部复发和并发症分别为 6 例 (19%) 和 10 例 (31%)。需要翻修手术的重建失败的患者有 2 例 (6%)。保肢治疗 30 例 (94%)。肌肉骨骼肿瘤协会功能评分的中位数为 61% (四分位间距,57%-70%),在内假体和切除关节置换组中相似。 结论: 肩关节外切除治疗骨肉瘤是一种有效的保肢方法。然而,局部复发仍然是一个主要问题。

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.
