Abstract

BACKGROUND:En-bloc sacrectomy is the treatment of choice for patients affected by sacral chordoma. It is a radical surgical procedure, which has to face the problem of handling fragile anatomic structures, such as the internal iliac vessels and the sacral nerve roots, with the risk of causing bowel, bladder, and sexual dysfunction. The combined anterior-posterior approach allows for a safer dissection of the tumor from the mesorectal fascia than the mere posterior approach, especially for tumors extending proximally to S3. Robotic surgery can improve the safety of the procedure. Sacral nerve stimulation is an accepted therapeutic option for fecal incontinence and may be used to treat postoperative incontinence. CASE PRESENTATION:We report on a patient affected by sacral chordoma with en-bloc sacrectomy preceded by a robotic-assisted dissection of the mesorectal fascia and on managing the postoperative fecal incontinence by implanting a sacral nerve stimulator on the first postoperative day. To our knowledge this is the first such procedure in the literature. CONCLUSIONS:From our experience, a robotic anterior approach increases safety for the organs in the pelvis when performing a sacrectomy. Moreover, a sacral nerve stimulator should be considered to manage neurologic complications following transection of nerve roots after sacrectomy.

摘要

背景: 整块骶骨切除术是骶骨脊索瘤患者的首选治疗方法。这是一种根治性手术,必须面对处理脆弱解剖结构的问题,如髂内血管和骶神经根,有引起肠、膀胱、和性功能障碍。前后联合入路比单纯的后入路更安全地将肿瘤从直肠系膜筋膜剥离,特别是对于向近端延伸到s3 的肿瘤。机器人手术可以提高手术的安全性。骶神经刺激是大便失禁公认的治疗选择,可用于治疗术后尿失禁。 案例演示: 我们报道了 1 例受骶骨脊索瘤影响的患者,在骶骨整块切除之前,机器人辅助解剖直肠系膜筋膜,并通过在骶神经刺激器上植入治疗术后大便失禁。术后第一天。据我们所知,这是文献中的第一个这样的程序。 结论: 根据我们的经验,机器人前路手术在进行骶骨切除术时增加了骨盆器官的安全性。此外,骶骨切除术后切断神经根后,应考虑使用骶神经刺激器来处理神经系统并发症。

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.
