Abstract
Spine tumors, both primary and metastatic, impose significant morbidity and mortality on patients and physicians. Patient-reported outcomes are valuable tools to assess a patient's impression of their health status and enhance communication between physicians and patients. Various spine generic patient-reported outcome tools have traditionally been used but have not been validated in the spine tumor patient population. The Spine Oncology Study Group Outcome Questionnaire, which is disease-specific for the metastatic spine patient population, has been shown to have strong validity, even across multiple languages. Patient-Reported Outcomes Measurement Information System, which has recently been developed, employs computerized adaptive testing to assess multiple health domains. It has been shown to capture information in both generic and specific questionnaires and has the potential to be used as a universal tool in the spine oncology patient population. Further long-term studies, as well as, cross-cultural adaptations, are needed to validate Patient-Reported Outcomes Measurement Information System's applicability and effectiveness.

Abstract
PURPOSE As an important treatment for spinal metastasis, surgery has strict applicable conditions. Although various organizations have formulated different guidelines on surgical treatment for spinal metastasis (SM), there are certain differences in the content, standardization and quality of the guidelines and it is necessary to make a critical appraisal of them. We aim to systematically review and appraise the current guidelines on surgical treatments of SM and summarize the related recommendations with the quality evaluation of supporting evidence, as to provide a reference for the standardization of surgical treatment plans, and help clinical front-line medical workers can make safe and effective clinical decisions faster. METHODS We searched Pubmed, Web of Science, and Embase for three major databases and online guideline databases. According to certain inclusion and exclusion criteria, the latest guidelines on the surgical treatment of SM were sorted out. AGREE II was used to evaluated the guideline's quality, and we extracted and compared the recommended treatment content of each guideline with evaluating by the evidence-grading scale. RESULTS Eight guidelines from 2013 to 2019 were included. Seven guidelines are comprehensive guidelines and one related to the reconstructive surgery of SM. Five guidelines were evaluated as "recommended," and three guidelines were evaluated as "recommended with modifications." Regarding the indications of surgery with SM, four guidelines, seven guidelines, seven guidelines, three guidelines and three guidelines recommended surgical treatment for patients with SM with intractable pain, mechanical instability, metastatic epidural spinal cord compression (MESCC), recurrent spinal metastasis (RSM), and survival predication, respectively. Regarding the surgical strategies, three guidelines recommended minimally invasive therapy but had strict indications. Six guidelines and five guidelines recommend palliative surgery and with receiving radiation therapy, respectively. For the aggressive surgery, only one guideline recommended to apply to patients in good general conditions who has isolated symptomatic SM. Regarding the surgical reconstructions, one guideline didn't recommend iliac bone graft and three guidelines recommended PMMA bone cement. CONCLUSION Most of the guidelines do not provide clear criteria for surgical application and provide more of a basic framework. The level of evidence for these surgical recommendations ranges from LOE B to D, and almost all guidelines recommend vertebroplasty and kyphoplasty, but for palliative and more aggressive surgery, which recommended to personalize specific surgical strategies with multidisciplinary collaboration.

Abstract
STUDY DESIGN A literature review. OBJECTIVE The aim of this review is to provide an overview of benign and malignant primary spine tumors and a balanced analysis of the benefits and limitations of (and alternatives to) surgical treatment with en bloc resection. SUMMARY OF BACKGROUND DATA Primary spine tumors are rare but have the potential to cause severe morbidity, either from the disease itself or as a result of treatment. The prognosis, goals, and treatment options vary significantly with the specific disease entity. Appropriate initial management is critical; inappropriate surgery before definitive treatment can lead to recurrence and may render the patient incurable, as salvage options are often inferior. METHODS We performed a comprehensive search of the PubMed database for articles relevant to primary spine neoplasms and en bloc spine surgery. Institutional review board approval was not needed. RESULTS Although Enneking-appropriate en bloc surgery can be highly morbid, it often provides the greatest chance for local control and/or patient survival. However, there is growing data to support modern radiotherapy as a feasible and less morbid approach to certain primary neoplasms that historically were considered radioresistant. CONCLUSIONS Choosing the optimal approach to primary spine tumors is complex. A comprehensive and up-to-date assessment of the evidence is required to guide patient care and to balance the often-competing goals of prolonging life and preserving quality of life.

Surgical outcomes and risk factors for surgical complications after en bloc resection following reconstruction with 3D-printed artificial vertebral body for thoracolumbar tumors. World J Surg Oncol 2023; 21:385. [PMID: 38097982 PMCID: PMC10720146 DOI: 10.1186/s12957-023-03271-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Accepted: 12/05/2023] [Indexed: 12/18/2023] Open
Abstract
BACKGROUND The outcomes of patients with tumors of the thoracolumbar spine treated with en bloc resection (EBR) using three-dimensional (3D)-printed endoprostheses are underreported. METHODS We retrospectively evaluated patients with thoracolumbar tumors who underwent surgery at our institution. Logistic regression analysis was performed to identify the potential risk factors for surgical complications. Nomograms to predict complications were constructed and validated. RESULTS A total of 53 patients with spinal tumors underwent EBR at our hospital; of these, 2 were lost to follow-up, 45 underwent total en bloc spondylectomy, and 6 were treated with sagittal en bloc spondylectomy. The anterior reconstruction materials included a customized 3D-printed artificial vertebral body (AVB) in 10 cases and an off-the-shelf 3D-printed AVB in 41 cases, and prosthesis mismatch occurred in 2 patients reconstructed with the off-the-shelf 3D-printed AVB. The median follow-up period was 21 months (range, 7-57 months). Three patients experienced local recurrence, and 5 patients died at the final follow-up. A total of 50 perioperative complications were encountered in 29 patients, including 25 major and 25 minor complications. Instrumentation failure occurred in 1 patient, and no prosthesis subsidence was observed. Using a combined surgical approach was a dependent predictor of overall complications, while Karnofsky performance status score, lumbar spine lesion, and intraoperative blood loss ≥ 2000 mL were predictors of major complications. Nomograms for the overall and major complications were constructed using these factors, with C-indices of 0.850 and 0.891, respectively. CONCLUSIONS EBR is essential for the management of thoracolumbar tumors; however, EBR has a steep learning curve and a high complication rate. A 3D-printed AVB is an effective and feasible reconstruction option for patients treated with EBR.

Abstract
Total en bloc spondylectomy (TES) is an effective treatment for spinal tumors. However, its complication rate is high, and the corresponding risk factors remain unclear. This study aimed to clarify the risk factors for postoperative complications after TES, including the patient's general condition, such as frailty and their levels of inflammatory biomarkers. We included 169 patients who underwent TES at our hospital from January 2011-December 2021. The complication group comprised patients who experienced postoperative complications that required additional intensive treatments. We analyzed the relationship between early complications and the following factors: age, sex, body mass index, type of tumor, location of tumor, American Society of Anesthesiologists score, physical status, frailty (categorized by the 5-factor Modified Frailty Index [mFI-5]), neutrophil-to-lymphocyte ratio, C-reactive protein/albumin ratio, preoperative chemotherapy, preoperative radiotherapy, surgical approach, and the number of resected vertebrae. Of the 169 patients, 86 (50.1%) were included in the complication group. Multivariate analysis showed that high mFI-5 scores (odds ratio [OR] = 2.99, p < 0.001) and an increased number of resected vertebrae (OR = 1.87, p = 0.018) were risk factors for postoperative complications. Frailty and the number of resected vertebrae were independent risk factors for postoperative complications after TES for spinal tumors.

Abstract
STUDY DESIGN Systematic review. OBJECTIVE En bloc resection is a major, invasive surgical procedure designed to completely resect a vertebral tumor with a sufficient margin. It is technically demanding and potentially poses risks of perioperative complications. In this systematic review, we investigated the incidence of complications after en bloc resection for spinal tumors. METHODS We screened PubMed and Embase databases for relevant English publications, from 1980 to 2020, using the following terms: spine OR spinal AND en bloc AND tumor. Using a standard PRISMA template, after the initial screening, full-text articles of interest were evaluated. RESULTS Thirty-six studies with 961 patients were included. The overall mean age of patients was 49.6 years, and the mean follow-up time was 33.5 months. There were 560 complications, and an overall complication rate of 58.3% (560/961). The 5 most frequent complications were neurological damage (12.7%), hardware failure (12.1%), dural tear and cerebrospinal fluid leakage (10.6%), wound-related complications (7.6%) and vascular injury and bleeding (7.3%). The complication-related revision rate was 10.7% (103/961). The average incidence of complication-related death was 1.2% (12/961). CONCLUSIONS En bloc resection is a surgical procedure that is very invasive and technically challenging, and the possible risks of perioperative complications should not be neglected. The overall complication rate is high. However, complication-related death was rare. The advantages of surgery should be weighed against the serious perioperative morbidity associated with this technique.

Medium to long term follow-up of survival and quality of life in patients with primary tumors of the cervical spine: Experience From a large single center. Front Surg 2023; 9:1011100. [PMID: 36684347 PMCID: PMC9852619 DOI: 10.3389/fsurg.2022.1011100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Accepted: 11/28/2022] [Indexed: 01/07/2023] Open
Abstract
Objectives To evaluate the survival and medium to long term health-related quality of life (HRQoL) of patients with primary cervical spinal tumors in a cross-sectional study and to identify any significant associations with demographic or clinical characteristics. Methods Patients diagnosed with primary cervical spinal tumors were retrospectively enrolled and their clinical, radiologic, and follow-up data (specifically the EQ-5D questionnaire) were collected. Univariate and multivariate Cox time-dependent regression analyses were performed to examine the significance of certain variables on overall survival. Univariate and multivariate logistic regression analyses were conducted to identify variables significant for overall HRQoL and each dimension of the EQ-5D. Results A total of 341 patients were enrolled in the study with a mean follow-up of 70 months. The diagnosis was benign in 246 cases, malignant in 84, and unconfirmed in 11. The 5-year overall survival rate was 86% and the 10-year overall survival rate was 65%. Multivariate analysis suggested that surgical treatment (P = 0.002, hazard ratio [HR] = 0.431, 95% CI. [0.254, 0.729]), benign and malignant tumors [P < 0.001, HR = 2.788, 95% CI. (1.721, 4.516)], tumor and surrounding normal tissue boundary [P = 0.010, HR = 1.950, 95% CI. (1.171, 3.249)], and spinal instability [P = 0.031, HR = 1.731, 95% CI. (1.051, 2.851)] still had significant effects on survival. Conclusions In this cross-sectional study, we evaluated the survival period and medium and long-term health-related quality of life of patients with primary tumors of the cervical spine, and analyzed the significant related factors of tumor clinical characteristics. Surgery, myelopathy, malignancy, spinal pain relieved by lying down or supine position, and tumor infiltration on MRI were significant predictors for overall survival. Enneking stage and age were significant predictors for HRQoL.

Abstract
Introduction Intramedullary spinal cord tumors (IMSCTs) are rare but clinically significant entities that may cause severe neurological decline with progressive pain and motor or sensory deterioration. Beyond the beneficial effects of surgical treatment and the long-term progression-free survival, neurological deficits may still persist after surgery, and information about the long-term patients' health-related quality of life (QoL) is still lacking. In this study, we investigate the patients' health perception 15 years after the surgery in an overall patients' wellbeing framework. Methods Patients surgically treated for IMSCT over a period from 1996 to 2011 were selected. After a mean of 15 years from the surgery, patient's self-administered questionnaire on disability, pain, sleep quality, and QoL was collected and neurological postoperative evaluation at the chronic stage was reexamined. Results Neurological deficits are reported in half of the patients in the postoperative chronic phase. After 15 years of surgery, half of the patients still report mild or severe disability grades associated with significantly higher pain and poor sleep and QoL. In accordance, the neurological condition measured at the chronic stage is significantly related not only to disease-specific symptoms (i.e., pain) but even to sleep quality complaints and poor QoL, measured at 15 years follow-up. Conclusions Health-related QoL is an important secondary outcome in patients. Although the progression-free survival, worse postoperative neurological conditions could predict long-term sequelae reflecting patients' poor health perception. It suggests the importance of preserving patients' functional status and globally evaluating patients' wellbeing to handle disease-specific symptoms but even more general aspects of QoL.

Abstract
Background Total en bloc spondylectomy (TES) is a widely accepted surgical technique for primary spinal bone tumours but is frequently accompanied by substantial peri-operative blood loss. Prior studies have reported estimated blood loss (EBL) can reach up to 3,200 mL. The aim of this study is to estimate the blood loss during TES procedures performed in the last ten years at our tertiary referral centre and compare EBL with actual blood loss (ABL). Methods We performed a retrospective review of all cases managed surgically with TES referred to our centre between 2005 and 2015. We recorded the oncological characteristics of each tumour and surgical management in terms of resection margins, operative duration and instrumentation. Data relating to peri-operative blood loss was also recorded including an estimation of total blood loss, the use of cell salvage where applicable and transfusion rates. Results A total of 21 patients were found to meet our inclusion criteria. There were 11 men and 10 women, with a median age of 40 years. The mean total ABL was 3,310 mL. Total operation time ranged from 6.53 to 19.7 h. Compared to ABL, in 59% of cases EBL had been underestimated by an average of 78% by volume. The EBL of the remaining 41% cases had been overestimated by 43%. This was not statistically significant (P=0.373). Cell salvage was used in 62% patients with a mean blood loss of 2,845 mL (884-4,939 mL) and transfusion of 3.8 units (0-12 units) versus 4,069 mL (297-8,335 mL) and 9.3 units (0-18 units) in those not managed with cell salvage. There was no significant difference in ABL between the cell salvage and non-cell salvage groups. Conclusions We report one of the largest case series in TES for primary bone tumours. EBL is not a reliable predictor for ABL. A large blood loss should be anticipated and use of cell salvage is recommended.

Abstract
BACKGROUND Total en bloc spondylectomy (TES) was designed to achieve oncological complete tumor resection in a vertebral compartment. Because of the special anatomy of the lumbosacral junction, TES procedure at the L5 level is a challenge, and it has been explained in few reports in the literature. Performing TES in the lower lumbar region, as normal, is accomplished by using a combined approach. OBSERVATIONS The authors presented the case of a 20-year-old man with an isolated spinal metastasis at the L5 level of carcinoid tumor of jejunum, limited to the vertebral body. Due to good long-term prognosis, after multidisciplinary evaluation the authors decided to treat the patient with TES through a combined posteroanterior approach, with posterior instrumentation and anterior reconstruction. Nine years after surgery, the patient was asymptomatic, with no sign of local recurrence. LESSONS TES is a feasible technique to provide long-term survival in a select subgroup of patients, reducing the risk of local recurrence. The authors presented some anatomical and biomechanical factors that must be considered at the lumbosacral region. Despite the high rates of complication associated with TES, most patients benefit from local control provided by the technique.

Abstract
Background:Extradural spinal tumors arise from soft or bony tissues in the spine and account for majority of spinal tumors. Interest in the unilateral biportal endoscopic (UBE) technique is rising, because it can easily decompress the bony spinal canal and accommodate all open surgical instruments under endoscopic guidance. However, reports of this technique have been limited to certain diseases. This study first demonstrates the UBE technique for extradural tumor biopsy and removal, and percutaneous stabilization in a 72-year-old female patient with dramatic symptom improvement.MethodsWe used the UBE technique for decompression and the percutaneous screw fixation technique for stabilization in a patient with an extradural mass compressing the thecal sac and destroying the posterior element. Under endoscopic guidance, a unilateral approach was used, and decompression and flavectomy were performed bilaterally. After decompression, tumor removal and biopsy were performed using various forceps and biopsy needles. After confirming sufficient spinal canal decompression, the screw was placed percutaneously. We evaluated the technical process of the procedure, the patient's pre- and postoperative pain (using the visual analog scale), and operative radiology and pathologic results.ResultsPostoperative pain and disability improved clinically, and spinal alignment stabilized radiologically. As the pathology findings confirmed an aneurysmal bone cyst, the treatment was completed without adjuvant therapy.ConclusionsWe treated an unstable spine due to an extradural tumor with the UBE and percutaneous screw techniques.

Abstract
BACKGROUND In en bloc vertebrectomy, the posterior approach is associated with limited access to anterior structures (vertebral body, esophagus, aorta, azygos vein). Video-assisted thoracoscopic surgery (VATS) might prove to be advantageous during thoracic en bloc vertebrectomy by allowing a combined anterior-posterior access in the prone position. We describe the technique and review the outcomes of 33 cases of video-assisted thoracoscopic en bloc vertebrectomy. METHODS A retrospective, single-center cohort study included all cases of VATS with a minimum follow-up of 1 year. A team of thoracic and orthopaedic surgeons performed the surgical procedure with the patient in a single, prone position. Anterior release was carried out thoracoscopically, followed by posterior en bloc tumor removal. RESULTS From 2003 to 2019, 33 patients were included. Nine patients underwent total vertebrectomy (8 had single-level and 1 had 3-level), and 24 patients underwent partial vertebrectomy (1 had single-level, 8 had 2-level, 13 had 3-level, and 2 had 4-level). Ten patients had pulmonary resection. Histology revealed 18 cases (55%) of primary bone tumors, 6 cases (18%) of lung cancer invading the spine, 6 cases (18%) of solitary metastasis, and 3 other cases (9%). The margins were tumor-free in 28 cases (85%). The median operative time was 240 minutes (range, 150 to 510 minutes), with a median blood loss of 1,200 mL (range, 400 to 6,700 mL), and there were 2 cases of conversion to thoracotomy. A total of 33 complications occurred in 18 patients (55%), and these were predominantly pulmonary. One death was surgery-related (infection). One patient had a persistent monoplegia. At a median follow-up of 63 months (range, 12 to 156 months), there were 21 surviving patients (64%) with 2 local recurrences and 1 distant recurrence, and 2 patients (6%) were lost to follow-up. The survival rates were 94% at 1 year, 71% at 2 years, and 68% at 5 years. CONCLUSIONS VATS en bloc vertebrectomy may be indicated for T2-to-T11 spine tumors with the exception of massive tumors, substantial chest wall and/or mediastinal invasion, and lung cancer exceeding 7 cm. The technique yielded satisfactory surgical and oncologic outcomes. LEVEL OF EVIDENCE Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Abstract
This study aims at identifying predictors of postoperative complications, lesion recurrence, and overall survival in patients undergoing en bloc spondylectomy (EBS) for spinal tumors. For this purpose a systematic review of the literature was conducted and patient-level data extracted. Linear-regression models were calculated to predict postoperative complications, lesion recurrence and overall survival based on age, tumor etiology, surgical approach, mode of resection (extra- vs. intralesional), tumor extension, and number of levels treated. A total of 582 patients were identified from the literature: 45% of females, median age 46 years (5-78); most common etiologies were: sarcoma (46%), metastases (31%), chordoma (11%); surgical approach was anterior (2.5%), combined (45%), and posterior (52.4%); 68.5% underwent EBS; average levels resected were 1.6 (1-6); average survival was 2.6 years; Complication rate was 17.7%. The following significant correlations were found: postoperative complications and resection mode (Odds ratio [OR] 1.35) as well as number of levels treated (OR 1.35); tumor recurrence and resection mode (OR 0.78); 5-year survival and age (OR 0.79), tumor grade (OR 0.65), tumor stage at diagnosis (OR 0.79), and resection mode (OR 1.68). EBS was shown to improve survival, decreases recurrence rates but also has a higher complication rate. Interestingly, the complication rate was not influenced by tumor extension or tumor etiology.

Abstract
OBJECTIVE Reconstruction of the mobile spine following total en bloc spondylectomy (TES) of one or multiple vertebral bodies in patients with malignant spinal tumors is a challenging procedure with high failure rates. A common reason for reconstructive failure is nonunion, which becomes more problematic when using local radiation therapy. Radiotherapy is an integral part of the management of primary malignant osseous tumors in the spine. Vascularized grafts may help prevent nonunion in the radiotherapy setting. The authors have utilized free vascularized fibular grafts (FVFGs) for reconstruction of the spine following TES. The purpose of this article is to describe the surgical technique for vascularized reconstruction of defects after TES. Additionally, the outcomes of consecutive cases treated with this technique are reported. METHODS Thirty-nine patients were treated at the authors' tertiary care institution for malignant tumors in the mobile spine using FVFG following TES between 2010 and 2018. Postoperative union, reoperations, complications, neurological outcome, and survival were reported. The median follow-up duration was 50 months (range 14-109 months). RESULTS The cohort consisted of 26 males (67%), and the median age was 58 years. Chordoma was the most prevalent tumor (67%), and the lumbar spine was most affected (46%). Complete union was seen in 26 patients (76%), the overall complication rate was 54%, and implant failure was the most common complication, with 13 patients (33%) affected. In 18 patients (46%), one or more reoperations were needed, and the fixation was surgically revised 15 times (42% of reoperations) in 10 patients (26%). A reconstruction below the L1 vertebra had a higher proportion of implant failure (67%; 8 of 12 patients) compared with higher resections (21%; 5 of 24 patients) (p = 0.011). Graft length, number of resected vertebrae, and docking the FVFG on the endplate or cancellous bone was not associated with union or implant failure on univariate analysis. CONCLUSIONS The FVFG is an effective reconstruction technique, particularly in the cervicothoracic spine. However, high implant failure rates in the lumbar spine have been seen, which occurred even in cases in which the graft completely healed. Methods to increase the weight-bearing capacity of the graft in the lumbar spine should be considered in these reconstructions. Overall, the rates of failure and revision surgery for FVFG compare with previous reports on reconstruction after TES.

Abstract
CASE We present a 65-year-old man with an L4 conventional chordoma. Total en bloc spondylectomy (TES) of the involved vertebral bodies and surrounding soft tissues with reconstruction of the spine using a free vascularized fibula autograft (FVFG) is a proven technique, limiting complications and recurrence. However, graft fracture has occurred only in the lumbar spine in our institutional cases. We used a technique in our patient to ensure extra stability and support, with the addition of a femoral allograft sleeve encasing the FVFG. CONCLUSIONS Our technique for the reconstruction of the lumbar spine after TES of primary malignant spinal disease using a femoral allograft sleeve encasing the FVFG is viable to consider.

Does facility volume influence survival in patients with primary malignant bone tumors of the vertebral column? A comparative cohort study. Spine J 2020; 20:1106-1113.

Abstract
BACKGROUND CONTEXT Facility volume has been correlated with survival in many cancers. This relationship has not been established in primary malignant bone tumors of the vertebral column (BTVC). PURPOSE To investigate whether facility patient volume is associated with overall survival in patients with primary malignant BTVCs. STUDY DESIGN Retrospective comparative cohort. PATIENT SAMPLE Adult patients with chordomas, chondrosarcomas, or osteosarcomas of the mobile spine. OUTCOME MEASURES Five-year survival. METHODS We retrospectively analyzed 733 patients with primary malignant BTVCs in the national cancer database from 2004 through 2015. Univariate and multivariate analyses were used to correlate specific outcome measures with facility volume. Volume was stratified based on cumulative martingale residuals to determine the inflection point of negative to positive impact on survival based on the patient cohort. Long-term survival was compared between patients treated at high and low volume using the Kaplan-Meier method. Only patients with malignant primary tumors were considered eligible for inclusion; patients with incomplete treatment data or benign tumors were excluded. RESULTS Patients treated at high-volume centers (HVCs) were younger (p=.0003) and more likely to be insured (p<.0001). There were no significant differences in tumor characteristics. Patients treated at high-volume facilities had improved 5-year survival of 71% versus 58% at low-volume centers (p<.0001). Patients treated at HVCs were more likely to receive surgical treatment (91% vs. 80%, p<.0001); if surgery was performed, they were more likely to undergo an en bloc resection (48% vs. 30%, p<.0001). However, there were no differences in margin status or utilization of radiotherapy or chemotherapy between HVCs and low-volume centers. In a multivariate analysis, facility volume was independently associated with improved survival overall (HR 0.75 [0.58-0.97], p=.03). CONCLUSIONS Primary malignant BTVCs are rare, even for HVCs. Despite this, patient survival was significantly improved when treatment was performed at HVCs.

OBJECTIVE To report the clinical and radiographic outcomes of single-stage posterior total en bloc spondylectomy (TES) of lumbar spinal metastases. PATIENTS AND METHODS From January 2012 to January 2015, 20 consecutive cases with lumbar spinal metastases who received single-stage posterior TES were retrospectively analyzed. A visual analog scale (VAS) was used to evaluate patients' pain status, American Spinal Injury Association (ASIA) classification was used to evaluate neurological status, and Eastern Cooperative Oncology Group (ECOG) score system was used to evaluate patients' performance status at pre- and post-operation and final follow-up. In addition, Intraoperative blood loss, operative time, postoperative complications, local kyphosis angle, and the postoperative duration of hospital stay were analyzed. RESULTS The median follow-up time was 16 months (ranging from 3 to 39 months), and 4 patients were still alive at the last follow-up. The mean amount of intraoperative blood loss and operation time was 970 mL and 232.5 min, respectively. The average VAS score improved from 7.5 preoperative to 2.8 postoperative and 3.2 at the last follow-up. Postoperative complications occurred in 3 cases. Sixteen patients died within 2 years after surgery, 10 of which died within 1 year. In the remaining 4 patients, the mean follow-up period was 37.25 months. One case of local recurrence occurred but no implant failure presented during follow-up. CONCLUSIONS Single-stage posterior TES is a challenging but rewarding procedure in the treatment of lumbar spinal metastases. Due to unique anatomy and biomechanics, surgeons should be aware of important vessels, and nerve root injury should be avoided.

Abstract
The main goal of treatment in spinal metastatic patients is local control of the disease, pain relief and the maintenance of ambulation. Traditionally, wide surgical resection of the tumour followed by adjuvant radiation and/or chemotherapy has been recommended. Currently, single-fraction or hypofractionated stereotactic body radiation therapy (SBRT) yields a one-year local control rate of over 95% with minimum morbidity, even for tumours previously considered radioresistant. In addition, by posterolateral and circumferential decompression and stabilisation of the spinal cord, it is feasible to create a 2 to 3 mm epidural margin between the dura mater and the tumour (separation surgery), enough to deliver safe and ablative doses of SBRT to the vertebrae. As these patients tend to be frail, such interventions should ideally be minimally invasive, thereby reducing surgical aggressiveness and helping to minimise the delay of any systemic therapies.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVES (1) To assess patient-reported outcomes-physical function, pain, and quality of life-in patients who underwent resection of a mobile spine chondrosarcoma. (2) To assess complications (90 days), readmissions, reoperations, oncological outcomes, and neurologic status. METHODS Thirty-three patients with spinal conventional chondrosarcoma resection between 1984 and 2014 at one hospital were included. The primary outcome measures were-minimally 6 months after surgery-the EuroQol 5 Dimensions (EQ5D), PROMIS-Physical Function, PROMIS-Pain Intensity, and Oswestry (ODI) Disability Index, or Neck (NDI) Disability established in 14 out of 20 alive (70.0%) patients. Complications, readmission, reoperations, oncological outcomes, and neurological status were reported for the complete cohort of 33 patients. RESULTS After spine chondrosarcoma resection, patients (n = 14) reported worse physical function (median 43, range 22-61, P = .026), worse quality of life (median EQ5D 0.70, range 0.04-1, P = .022), and comparable pain intensity (median 47, range 31-56, P = .362) when compared with US general population values. The median NDI/ODI was 25 (range 0-72) indicating mild to moderate disability. Patients undergoing reoperation had worse patient-reported outcomes than those who did not. Eighteen (55.5%) out of 33 patients suffered complications (90 days), 14 (42.4%) had unplanned readmission, and 13 (39.4%) underwent reoperation. Intralesional resection was associated with increased readmission, reoperation, and recurrence rate. CONCLUSIONS Chondrosarcoma affects quality of life and physical function and its treatment frequently results in complications and reoperations. Our findings can be used to inform future patients about expected outcomes.

Abstract
PURPOSE Knowledge about quality of life (QOL), pain, and psychological factors in patients with primary tumors of the spine is limited, but is important in planning rehabilitation after surgery. Aims of this study were to assess the preoperative levels and improvement after surgery of these factors, and to identify the predictors of postoperative pain and QOL. METHODS Patients with primary tumors undergoing spine surgery were matched for sex and age with patients with metastatic tumors. QOL was measured at baseline and three months after surgery with the physical (PCS) and mental (MCS) components SF-12 subscales, pain intensity with a numeric rating scale (NRS), depression with the Beck Depression Inventory (BDI). Preoperative SF-12, NRS, and BDI levels and differences in follow-up improvement in SF-12 and NRS were compared across samples. LASSO regressions were performed to find predictors of follow-up SF-12 and NRS. RESULTS Patients with primary tumors showed better PCS and NRS, and similar BDI and MCS than patients with metastatic tumors. At follow-up, they showed stronger improvement in the MCS and no improvement in the PCS. All QOL scores were below those of the general population. Follow-up PCS was predicted by baseline PCS and BDI; MCS by baseline MCS; pain intensity by baseline pain intensity and BDI. CONCLUSION Patients with primary tumors of the spine suffer from moderate levels of physical and mental impairment. Depression influences surgical outcomes.

Abstract
BACKGROUND Total en bloc spondylectomy (TES) significantly decreases the rate of local recurrence and provides long-term survival in patients with malignant tumor of the spine. This procedure can be performed through a posterior-only approach. However, TES for lower lumbar spine through a posterior-only approach is technically challenging. METHODS We retrospectively reviewed 9 patients with solitary metastatic tumors of the fourth lumbar spine who underwent TES in a posterior-only approach from June 2012 to December 2015. This series included 5 female and 4 male patients, with a mean age of 54.1 years. Endpoints included length of surgery, estimated blood loss, visual analogue scale for pain, instrumentation failure, perioperative complications, local control rate, and overall survival. RESULTS All patients underwent TES and circumferential reconstruction of the involved level. Average operative time and estimated blood loss were 282 minutes and 2421 mL, respectively. The mean follow-up time was 41.2 months. We encountered nerve roots stretches in all patients during the surgeries. Three patients experienced acute lower-extremity neurologic dysfunction, but the symptoms were significantly alleviated in 4 weeks postoperatively and fully resolved within 6 months. Five patients showed no evidence of disease at the latest follow-up. Three patients died of metastasis and systemic failure. One patient developed new metastases and was alive with disease. Titanium mesh cage subsidence was observed in 3 patients, but no implant failures or related clinical symptoms were found. CONCLUSIONS TES for the fourth lumbar spine in a posterior-only approach is feasible. Although the surgery is challenging, long-term oncologic and neurologic outcomes are satisfying.

Abstract
OBJECTIVE In 2013, we reported a case of combined anterior and posterior reconstruction after three-level en bloc vertebral body replacement and replacement of the aorta for chondrosarcoma of the thoracic spine. Eight years after, we observed an implant failure and now report on revision strategy and 2-year follow-up (f/u) after revision. METHODS We report about the 2-year f/u of the same now 51-year-old gravedigger who needed to undergo revision surgery after implant failure. We did a combined anterior and posterior correction vertebral interbody fusion by (1) removal of broken screws in Th9 and L2, removal of broken titanium bars, correction of kyphosis, enhancement of the vertebral interbody fusion from Th8 to L4 using monoaxial titanium screws and cancellous bone transplantation and (2) removal of the broken plate and the loose cage, implantation of a novel expandable PEEK cage from Th11 to L1 and anterior stabilization from Th9/10 to L2/3, as well as autologous and allogeneic cancellous bone transplantation. RESULTS Two years after revision surgery, the patient presented fully reintegrated without any complains. No painkillers needed to be taken. Pain was reported with 2 out of 10 on the VAS. CONCLUSION Both procedures offer a good primary stabilization with excellent pain reduction and good return to life. Limited information on long-term survivors is known. Therefore, the theoretical advantage of a biological solution needs to be checked in the long-term f/u for consistency.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVE To evaluate the clinical outcome of palliative surgery using posterior decompression and fixation combined with intraoperative vertebroplasty (PDFIV) for the treatment of spinal metastases, and analyze the indications for PDFIV using a neurological, oncologic, mechanical, and systemic framework. SUMMARY OF BACKGROUND DATA Palliative surgery is widely used to spinal metastatic patients with poor condition for enough postoperative recovery. PDFIV which is a new palliative surgery is rarely reported its efficacies and indications. METHODS A retrospective analysis of 26 consecutive patients with spinal metastases treated by PDFIV was performed. The group includes 18 men and 8 women with an average age of 55.7 years (range, 47-79 y). All patients presented with local pain, 18 patients had compressive myelopathy, and 9 had radiculopathy. The total segments involved were 32. Postoperative imaging was used to evaluate cement leakage, the status of fixation, and recurrence. The visual analogue score and Frankel grade were used to identify neurological function. RESULTS There were no intraoperative neurological or vascular injuries. The mean operative time was 173 minutes (range, 125-245 min), the mean blood loss was 659 mL (range, 350-2500 mL), and the average amount of cement used in the vertebrae was 4.1 mL (range, 2.0-5.5 mL). All patients were followed for an average of 25 months (range, 6-56 mo). The visual analogue score decreased from 8.1 preoperatively to 2.1 postoperatively. Fifteen of 18 patients with compressive myelopathies had improved Frankel grades. Postoperative computed tomography scans showed cement leakage in 3 patients (11.5%); however, all of the leakages were clinically asymptomatic. There were local tumor recurrences requiring reoperation in 2 patients. CONCLUSIONS Palliative surgery using PDFIV can improve neurological function and alleviate pain effectively, and allow low cement leakage and timely disposal of leakage combined with intraoperative visual vertebroplasty.

Abstract
BACKGROUND Total en bloc spondylectomy (TES) for the treatment of spinal tumors decreases local recurrence and improves survival compared with intralesional resection. TES approaches vary in both the number of stages to complete the procedure and instruments with which osteotomies are performed. METHODS We describe a 2-stage technique that employs the use of threadwire saws. We performed a retrospective review of cases of primary tumors and solitary metastases involving the thoracic or lumbar spine treated with use of our modified technique at our institution between 2010 and 2016, identifying eligible patients by searching for specific phrases in operative reports found in our oncologic database. Clinical notes, operative notes, imaging reports, and pathology reports were reviewed for all patients. RESULTS Thirty-three patients underwent our modified technique, in which we pass a threadwire saw between the vertebral body and the thecal sac. The most common tumor type was chordoma (64%), and tumors were most commonly located in the lumbar spine (61%). There were no intraoperative injuries to the spinal cord or great vessels. One patient experienced a dural tear secondary to the passage of a saw. Seventeen (52%) of the patients had perioperative complications, with 1 death. Seven (22%) of the patients had complications occurring within 90 days after discharge, and 8 (25%) had complications occurring >90 days after discharge. Instrumentation failure was observed in 8 cases (25%). Negative margins were obtained in 94% of the cases. Local recurrence was observed in 2 cases (6%). The majority of patients had normal motor function at the time of the most recent follow-up. CONCLUSIONS Our modified en bloc spondylectomy represents an effective technique for the resection of spinal tumors in selected patients, allowing for visualization of vessels anterior to the spine and the avoidance of spinal cord injury. LEVEL OF EVIDENCE Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Abstract
AIMS The aim of the study was to compare measures of the quality of life (QOL) after resection of a chordoma of the mobile spine with the national averages in the United States and to assess which factors influenced the QOL, symptoms of anxiety and depression, and coping with pain post-operatively in these patients. PATIENTS AND METHODS A total of 48 consecutive patients who underwent resection of a primary or recurrent chordoma of the mobile spine between 2000 and 2015 were included. A total of 34 patients completed a survey at least 12 months post-operatively. The primary outcome was the EuroQol-5 Dimensions (EQ-5D-3L) questionnaire. Secondary outcomes were the Patient-Reported Outcome Measurement Information System (PROMIS) anxiety, depression and pain interference questionnaires. Data which were recorded included the indication for surgery, the region of the tumour, the number of levels resected, the status of the surgical margins, re-operations, complications, neurological deficit, length of stay in hospital and rate of re-admission. RESULTS The median EQ-5D-3L score was 0.71 (interquartile range (IQR) 0.44 to 0.79) which is worse than the national average in the United States of 0.85 (p < 0.001). Anxiety (median: 55 (IQR 49 to 61), p = 0.031) and pain (median: 61 (IQR 56 to 68), p < 0.001) were also worse than the national average in the United States (50), while depression was not (median: 52 (IQR 38 to 57), p = 0.513). Patients who underwent a primary resection had better QOL and less anxiety, depression and pain compared with those who underwent resection for recurrent or residual disease. The one- and five-year probabilities were 0.96 and 0.74 for survival, 0.07 and 0.25 for tumour recurrence, and 0.02 and 0.16 for developing distant metastasis. A total of 25 local complications occurred in 20 patients (42%), and there were 50 systemic and other complications in 25 patients (52%) within 90 days. CONCLUSION These patient reported outcomes and oncological and surgical outcomes can be used when counselling patients and to aid decision-making when planning surgery.

Abstract
Primary clear cell carcinoma of liver (PCCCL) is an uncommon variant of primary hepatocellular carcinoma. Though the literature describes a better prognosis in relation to the proportion of clear cells in the tumour when compared to the other variants, there is no general consensus in the management due to its rarity and unclear clinicopathological and prognostic factors. There is dearth of evidence with regard to the metastasizing nature of PCCCL and its management. In addition, the management of recurrent spinal tumours both primary and metastatic is not clear as the available evidence is mostly based on case reports. We describe an unusual presentation of PCCCL with solitary spinal metastasis and further complicated by tumour recurrence in a 71-year-old male. Such presentation has never been described before. He presented with low back pain and incomplete neurological deficits involving both lower limbs. On detailed evaluation, he was found to have a solitary metastasis at L3 vertebra secondary to PCCCL. He underwent radical excision of tumour and reconstruction for the solitary metastasis at L3 vertebral body and trans arterial chemo embolisation (TACE) for the hepatic lesion. Pt was asymptomatic until 9 months post operatively when he developed tumour recurrence at L3 vertebra. Patient subsequently underwent 2 stage palliative surgery followed by radiotherapy and chemotherapy. At his latest follow-up (1 year), the patient's overall general condition has improved with residual neurological deficits in the lower limb. PCCCL is a rare type of hepatocellular carcinoma which can present as "solitary metastasis" to the spine. Although the literature suggests a good prognosis for this histological type, this case did not have a good outcome. In addition to providing information for the management of similar cases in the future, this case report highlights that every patient has to be managed on a case-by-case basis.

Abstract
STUDY DESIGN Retrospective chart review. OBJECTIVE To determine the long-term efficacy of 2-stage total en bloc spondylectomy (TES). SUMMARY OF BACKGROUND DATA TES is a well-described technique to achieve tumor-free margins, but it is a highly destabilizing procedure that necessitates spinal reconstruction. A 2-stage anterior/posterior approach for tumor resection and instrumentation has been shown to be biomechanically superior to the single-stage approach in achieving rigid fixation, but few clinical studies with long-term outcomes exist. METHODS A retrospective review was performed on patients undergoing a 2-stage TES for a spinal tumor between 1999 and 2011. Results were compared with those from a literature review of case series, with a minimum of 2-year follow-up, reporting on a single-stage posterior-only approach for TES. RESULTS Seven patients were identified (average follow-up 52.7 mo). Tumor location ranged from T1 to L3 with the following pathologies: metastasis (n=3), hemangioma (n=1), leiomyosarcoma (n=1), giant cell tumor (n=1), and chordoma (n=1). There were no significant surgical complications. All 7 patients had intact spinal fixation. There were no failures of the orthogonal fixation (pedicle screws or anterior fixation). The average modified Rankin Scale scores improved from 2.7 preoperatively to 0.7 at last follow-up. None of the patients in our series suffered local disease recurrence at last follow-up or suffered neurological deterioration. These results were comparable with those noted in the literature review of posterior-only approach, where 12% of patients experienced instrument failure. CONCLUSIONS TES is a highly destabilizing procedure requiring reconstruction resistant to large multiplanar translational and torsional loads. A 2-stage approach utilizing orthogonal vertebral body screws perpendicular to pedicle screws is a safe and effective surgical treatment strategy. Orthogonal spinal fixation may lower the incidence of instrumentation failure associated with complete spondylectomy and appears to be comparable with a single-stage procedure. However, larger prospective series are necessary to assess the efficacy of this approach versus traditional means.

Abstract
STUDY DESIGN Analysis of prospectively collected longitudinal web-based registry data. OBJECTIVE To determine relative validity, responsiveness, and minimum clinically important difference (MCID) thresholds in patients undergoing surgery for intradural extramedullary (IDEM) spinal tumors. SUMMARY OF BACKGROUND DATA Patient-reported outcomes (PROs) are vital in establishing the value of care in spinal pathology. There is limited availability of prospective, quality studies reporting PROs for IDEM spine tumors. METHODS . A total of 40 patients were analyzed. Baseline, postoperative 3-month, and 12-month PROs were recorded: Oswestry Disability Index or Neck disability Index (ODI/NDI), Quality of life EuroQol-5D (EQ-5D), Short Form-12 (SF-12), Numeric Rating Scale (NRS)-pain scores. Responders were defined as those who achieved a level of improvement one or two, after surgery, on health transition index (HTI) of SF-36. Receiver-operating characteristic curves were generated to assess the validity of PROs, and the difference between standardized response means (SRMs) in responders versus nonresponders was utilized to determine the relative responsiveness of each PRO measure. MCID thresholds were derived using previously reported minimal detectable change approach. RESULTS A significant improvement across all PROs at 3-months and 12-months follow up was noted. The derived MCID thresholds were 13.9 points: ODI/NDI, 0.14 quality adjusted life years: EQ-5D, 2.8 points: SF-12PCS and 10.7 points: SF-12MCS, 1.9 points: NRS-back/neck pain, and 1.8 points: NRS-leg/arm pain. SF-12PCS was most accurate discriminator of meaningful improvement (area under the curve, AUC-0.83) and most responsive (SRM-1.36) to postoperative improvement. EQ-5D, ODI/NDI, NRS-pain scores were all accurate discriminator (AUC-0.7-0.8) and responsive measures (0.97-0.67) of meaningful postoperative improvement. SF-12MCS was neither a valid discriminator (AUC-0.48) nor a responsive measure (SRM: -1.5) of outcome. CONCLUSION Surgical resection of IDEM spinal tumors provides significant and sustained improvement in quality of life, general health, disability, and pain at 12-month after surgery. The surgically resected IDEM-specific clinically meaningful thresholds are reported. All the PROs reported in this study can accurately discriminate responders and nonresponder based on SF-36 HTI index except for SF-12 MCS. LEVEL OF EVIDENCE 3.

Abstract
STUDY DESIGN Systematic literature review. OBJECTIVE To investigate if evidence-based principles of oncologic resection for primary spinal tumors are correlated with an acceptable morbidity and mortality profile and satisfactory health-related quality of life (HRQOL) measures. SUMMARY OF BACKGROUND DATA Respecting oncologic principles for primary spinal tumor surgery is correlated with lower recurrence rates. These interventions are, however, often highly morbid. METHODS A systematic literature review was performed to address the objectives by searching MEDLINE and EBMR databases. Articles that met our inclusion criteria were reviewed. GRADE guidelines were used for recommendation formulation. RESULTS A total of 25 articles addressing the morbidity and mortality profile of primary spinal tumor surgery were identified. For sacral tumors, complication rates of up to 100% have been reported and complication-related death ranged from 0% to 27%. Mobile spine tumor complication rates varied from 13% to 73.7% and complication-related death ranged from 0% to 7.7%. Seven articles examining HRQOL for this patient population were identified. The limited literature showed comparable patient HRQOL profiles to those with benign conditions such as degenerative disc disease. CONCLUSION Respecting oncologic principles for primary spinal tumors are correlated with high adverse event rates. We recommend that primary spinal tumor surgeries be performed in experienced centers with multidisciplinary support teams and that prospective adverse event collection be promoted (strong recommendation/very low certainty of the evidence). Oncologic resection of primary tumors of the spine is associated with HRQOL that more closely approximates normative values with increasing duration of follow-up, but decreases with disease recurrence. We recommend primary spinal tumor surgery be performed with a curative intent whenever possible, even at the expense of greater initial morbidity to optimize long-term HRQOL (strong recommendation/very low certainty of the evidence).

Abstract
STUDY DESIGN Systematic review and consensus expert opinion. OBJECTIVE To provide surgeons and other health care professionals with guidelines for surgical reconstruction of metastatic spine disease based on evidence and expert opinion. SUMMARY OF BACKGROUND DATA The surgical treatment of spinal metastases is controversial. Specifically two aspects of surgical reconstruction are addressed in this study: (i) choice of bone graft used during surgery for metastatic spine tumors and (ii) the design of reconstruction or construct to stabilize. METHODS A systematic review of the available medical literature from 1980 to 2015 was conducted, and combined with consensus expert opinion from a recent survey of spine surgeons who treat metastatic spine tumors. RESULTS There is very little evidence in the literature to provide guidance on the use of bone graft in metastatic tumor reconstruction. There is little evidence in the literature to support the preferential use of one graft type over the other. Approximately, 41% of respondents said they used bone graft or bone graft substitutes to accomplish fusion. There were 17 studies that described the use of a prefabricated prosthetic, 10 studies describing the use of polymethyl methacrylate (PMMA) bone cement, and only three studies describing the use of bone graft for anterior column reconstruction. The use of structural allograft was most popular among the experts for anterior reconstruction, followed by cage reconstruction, and PMMA bone cement. CONCLUSION Achieving bony union may be of importance for the maintenance of spinal stability in the long term after reconstruction. Whether bony union is required for patients with shorter life expectancies is debatable. The literature supports the use of anterior reconstruction with either a prefabricated prosthetic or PMMA bone cement. It also supports the use of an anterior construct reinforced with bilateral posterior instrumentation when performing a three-column reconstruction. LEVEL OF EVIDENCE N/A.

Abstract
BACKGROUND High grade metastatic spinal tumors are most common and are invasive. These patients can succumb to disease progression if not treated timely. Although considered as invasive and morbid, total enbloc spondylectomy (TES) in selected cases has better survival rates. The authors describe the results of TES for high grade metastatic spinal tumors. MATERIALS AND METHODS Five patients (four females and one male) underwent TES for solitary metastatic vertebral lesion between November 2012 and January 2014. These patients presented to us with spinal instability, unrelenting severe spinal pain and/or with severe progressive radiculopathy. Average age was 46.2 years (range 39-62 years). After complete investigations, computed tomography scan, magnetic resonance imaging scan and positron emission tomography (PET) scan, it was confirmed that these patients had high grade solitary vertebral metastatic tumor. RESULTS Average duration of followup was 18 months (range 16-20 months). The average preoperative visual analog scale score of 9.4 (range 9-10) improved to 2 (range 1-4) at last followup. Average blood loss was 1440 mL (range 1000-2000 mL). Average duration of surgery was 198 min (range 180-240 min). Significant pain relief was noticed in each patient in the immediate postoperative period and during followups. These patients attained complete functional activities of daily living with in a month. The imaging showed implants in situ, no recurrence of tumor, and no activity on PET scan at the final followup. CONCLUSION The present series shows favorable short term results of TES for solitary, metastatic, high grade vertebral body tumors by a team approach.

Abstract
OBJECTIVE This study was to investigate the feasibility and efficacy of total en bloc spondylectomy (TES) combined with chest wall excision through a modified posterior approach in treating the patients with thoracic spinal tumor and posterior chest wall invasion. METHODS Clinical data of 21 consecutive patients (7 males, 14 females; average age: 41.5, range: 20-69) who underwent the combined TES and chest wall excision through a modified posterior approach from 08/2005 to 01/2014 were retrospectively analyzed. Reconstruction of the spinal defect following TES was accomplished by dorsal stabilization and carbon cage interposition. All resected specimens were examined histologically. Radiotherapy and chemotherapy were performed according to the results of the surgery and histological examination. All patients were followed up on a regular basis. RESULTS The surgery was successfully performed in all patients. Histological analysis revealed primary malignant tumors in 16 patients and solitary vertebral metastases in 5 patients. Three patients with preoperative neurologic deficits of Frankel D recovered to Frankel E 1-3 weeks postoperatively. After the mean follow-up of 31 months (9-70), the 16 patients (16/21, 76.2%) with primary bone tumors were free of recurrence and present no evidence of disease. Four cases (4/21, 19%) with metastatic tumor developed recurrence or distant metastases. Three patients presented with cerebrospinal fluid leakage and one patient suffered pneumonia; they were soon recovered after treatment. No other complications were observed. CONCLUSION The results suggest that the combined TES with chest wall excision via a modified posterior approach seems feasible and effective for treating patients with thoracic spinal tumor and posterior chest wall invasion.

Abstract
PURPOSE The purpose of this retrospective analyses was to evaluate the bone viability in the ventral column of the spine following large segmental defect reconstructions. Osseous integration of implants following spinal fusion procedures is an essential precondition to provide adequate mechanical strength to any applied forces and subsequently satisfying patient outcomes. Although CT scan is the non-invasive gold standard for fusion assessment, it lacks the ability to visualize bone viability and, therefore, discrepancy remains about sensitivity and specificity of CT as evaluation tool of spinal fusion. METHODS A novel modality, (18)F Fluoride PET/CT, specifically allows quantitative in vivo evaluation of metabolic activity of the osseous integration. Bone viability following large segmental reconstructions in patients after mono- and multi-level en bloc spondylectomies (EBS) was analyzed. Spinal fusion was assessed on plain radiographs and CT scans according to the FDA fusion criteria as well as (18)F PET/CT. RESULTS A total of eight patients underwent (18)F PET/CT were included (one 4-level-, one 3-level, two 2-level and four 1-level EBS). The average follow-up between EBS and radiographic studies was 24.8 months. On plain radiographs and CT scans, successful fusion was confirmed in all patients. However, (18)F PET/CT showed non-union in all cases. The metabolic bone activity within the cage was fourfold decreased compared to the reference vertebra, whereas the metabolic activity of the adjacent endplates was 1.6-fold increased compared to the reference vertebra. CONCLUSION This study suggests a discrepancy between fusion rates assessed by plain radiographs and CT scan compared to (18)F PET/CT.

Abstract
BACKGROUND CONTEXT Little has been reported regarding the patient-centered quality-of-life (QOL) outcomes after en bloc spondylectomy (ES). Despite lower local recurrence rates, it is unknown whether outcomes justify the surgical morbidity. PURPOSE The purpose of this study was to report on patient QOL after ES as measured by validated instruments and to identify factors that may predict better postoperative QOL. STUDY DESIGN This is a retrospective case-control study (Level III). PATIENT SAMPLE Thirty-five consecutive patients with mobile spine tumors were included. Twenty-seven patients underwent en bloc resection, whereas 8 patients received definitive radiation and no surgery. Minimum follow-up was 6 months (median, 32 months). OUTCOME MEASURES The outcome measures were European Quality Group 5-Dimensional Questionnaire (EQ5D), four Patient-Reported Outcome Measurement Information System (PROMIS) short-form metrics, Neck Disability Index, and Oswestry Disability Index (ODI). METHODS We performed statistical comparisons between the surgery and radiation groups, of the general US population, and within the study group itself to identify predictors of higher QOL scores. RESULTS We identified a significant difference in QOL between the surgery and radiation groups in only one instrument, PROMIS pain interference, with surgery having more pain interference (15.7 vs. 10.1, p=.04). For most metrics, including EQ5D, pain interference, pain behavior, and ODI, scores were around one standard deviation worse than the US population mean. Multivariable linear regression for each instrument demonstrated that preoperative factors such as better performance status, tumor location in the cervical spine, lack of mechanical back or neck pain, and shorter fusion span were independently predictive of better QOL scores. Postoperative factors such as poor performance status, chronic narcotic use, and local recurrence were more dominant than preoperative factors in predicting worse QOL. CONCLUSIONS Patients may experience more pain interference after surgery as opposed to definitive radiotherapy, but we did not identify a difference for most metrics. Quality of life in our study group was significantly worse than the general population for most metrics. Cervical tumors, lack of mechanical pain, better baseline performance status, and less extensive surgery predict better QOL after surgery.

Abstract
OBJECTIVE To report a large clinical series of primary bone tumors of the spine (PBTS) and review the current concepts of management. MATERIALS AND METHODS We retrospectively analyzed a clinical series of PBTS treated over the last decade (2004-2014) in the spine unit of a large European tertiary care center. Every PBTS was identified from an electronic medical-record system. Analysis comprised medical records and clinical imaging. Overall survival and outcome was measured using the Glasgow Outcome Scale (GOS) at six weeks, six months and one year postoperatively. Surgical management and adjuvant/neoadjuvant strategies were analyzed. A thorough review of the current literature was performed. RESULTS A total of 79 patients were included. Of these, 44 (55.7%) were male. The age ranged from 9 to 90 years (mean 55), and most patients were adults (93.6%). Local pain was the most common symptom and was present in 91.1% of the patients. The majority of the tumors occurred in the thoracic spine (52 patients, 65.8%). Overall 86% (68 patients) of PBTS were classified as malignant and at the time of diagnosis, 7 patients (8.9%) presented with non-spinal metastasis. The most common histologic types were hematopoietic tumors (72.2%), followed by chondrogenic ones (12.7%). Within hematopoietic tumors, plasmacytoma was the most frequent type (49 patients, 62%). In 12 patients (15.2%) recurrences were seen during the follow-up period. Overall mean survival of benign PBTS was 100%, malignant non-hematopoietic PBTS 50% and, malignant hematopoietic PBTS 84% at one year, respectively. At six weeks and one year after the initial surgery, 79% and 54% of the patients presented a GOS >3, respectively. CONCLUSION PBTS were almost exclusively seen in adults. Malignant tumors were markedly more frequent than benign tumors, with hematopoietic tumors being the most common type. For PBTS, early surgery is important in order to restore spinal stability and decompress the spinal cord. This allows pain reduction and prevention of neurological deficits.

Abstract
BACKGROUND Over the years, en bloc spondylectomy has proven its efficacy in controlling spinal tumors and improving survival rates. However, there are few reports of large series that critically evaluate the results of multilevel en bloc spondylectomies for spinal neoplasms. QUESTIONS/PURPOSES Using data from a large spine tumor center, we answered the following questions: (1) Does multilevel total en bloc spondylectomy result in acceptable function, survival rates, and local control in spinal neoplasms? (2) Is reconstruction after this procedure feasible? (3) What complications are associated with this procedure? (4) is it possible to achieve adequate surgical margins with this procedure? METHODS We retrospectively investigated 38 patients undergoing multilevel total en bloc spondylectomy by a single surgeon (AL) from 1994 to 2011. Indications for this procedure were primary spinal sarcomas, solitary metastases, and aggressive primary benign tumors involving multiple segments of the thoracic or lumbar spine. Patients had to be medically fit and have no visceral metastases. Analysis was by chart and radiographic review. Margin quality was classified into intralesional, marginal, and wide. Radiographs, MR images, and CT scans were studied for local recurrence. Graft healing and instrumentation failures at subsequent followup were assessed. Complications were divided into major or minor and further classified as intraoperative and early and late postoperative. We evaluated the oncologic status using cumulative disease-specific and metastases-free survival analysis. Minimum followup was 24 months (mean, 39 months; range, 24-124 months). RESULTS Of the 38 patients, 34 (89%) were alive and walking without support at final followup. Thirty-one (81%) had no evidence of disease. Two patients died postoperatively and another two died of systemic disease (without local recurrence). Only three patients (8%) had a local recurrence. There were 14 major complications and 22 minor complications in 25 patients (65%). Only one patient required revision of implants secondary to mechanical failure. Two cases of cage subsidence were noted but had no clinical significance. Wide margins were achieved in nine patients (23%), marginal in 25 (66%), and intralesional in four (11%). CONCLUSIONS In patients with multisegmental spinal tumors, oncologic resections were achieved by multilevel en bloc spondylectomy and led to an acceptable survival rate with reasonable local control. Multilevel en bloc surgery was associated with a high complication rate; however, most patients recovered from their complications. Although the surgical procedure is challenging, our encouraging mid-term results clearly favor and validate this technique. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
BACKGROUND CONTEXT Spine metastases occur frequently in patients with cancer. A variety of surgical approaches, including anterior transcavitary, lateral extracavitary, posterolateral, and/or combined techniques are used for spinal cord decompression and restoration of spinal stability. The incidence of symptomatic hardware failure is unknown for the majority of these approaches. PURPOSE The purpose of this study was to determine the incidence of symptomatic hardware failure and the associated risk factors in patients with metastatic epidural spinal cord compression (MESCC). STUDY DESIGN/SETTING This was a retrospective study. PATIENT SAMPLE The current series analyzes a cohort of 318 patients who underwent separation surgery, which involves single-stage posterolateral decompression and posterior segmental instrumentation for MESCC. OUTCOME MEASURES The event of interest was hardware failure; the competing event was death resulting from any cause. All patients were monitored for survival analysis. A competing risk analysis was conducted to examine univariately a number of potential risk factors associated with hardware failure, including junctional level, gender, construct length, and the presence or absence of prior chest wall resection. METHODS A retrospective analysis and chart review were performed for 318 consecutive patients who underwent posterolateral decompression and posterior screw-rod fixation without supplemental anterior fixation from March 2004 to June 2011 at our institution. The median follow-up time for survivors without hardware failure was 399 days (range, 9-2,828), with a mean operative time of 3 hours. A total of 78% of patients died during the 7-year study period. RESULTS Of the 318 patients, nine (2.8%) exhibited signs and symptoms of hardware failure and required revision of the instrumentation. Patients with chest wall resection and those with initial construct length greater than six contiguous spinal levels exhibited a statistically significantly higher risk of symptomatic hardware failure than their counterparts. We observed a trend toward an increased risk of failure in women compared with men (p=.09). CONCLUSIONS The incidence of hardware failure is low in patients with MESCC who undergo posterolateral decompression and posterior screw-rod instrumentation. Moreover, the short operative time and low morbidity profile associated with this approach make it a reliable and acceptable method for the surgical treatment of MESCC. Patients with constructs spanning six or more levels or those with prior chest wall resection are at higher risk for instrumentation failure.

Abstract
Assessing the prognosis before treatment for metastatic spine tumor is extremely important in therapy selection. Therefore, we review some prognostic scoring systems and their outcomes. Articles with combinations of two keywords among “metastatic spine tumor” and “prognosis”, “score”, “scoring system”, “predicting”, or “life expectancy” were searched for in PubMed. As a result, 236 articles were extracted. Those referring to representative scoring systems about predicting the survival of patients with metastatic spine tumors were used. The significance and limits of these scoring systems, and the future perspectives were described. Tokuhashi score, Tomita score, Baur score, Linden score, Rades score, and Katagiri score were introduced. They are all scoring systems prepared by combining factors that affect prognosis. The primary site of cancer and visceral metastasis were common factors in all of these scoring systems. Other factors selected to influence the prognosis varied. They were useful to roughly predict the survival period, such as, “more than one year or not” or “more than six months or not”. In particular, they were utilized for decision-making about operative indications and avoidance of excessive medical treatment. Because the function depended on the survival period in the patients with metastatic spine tumor, it was also utilized in assessing functional prognosis. However, no scoring system had more than 90% consistency between the predicted and actual survival periods. Future perspectives should adopt more oncological viewpoints with adjustment of the process of treatment for metastatic spine tumor.

Abstract
Advances in oncological and surgical therapies have led to a significant increase in life expectancy of cancer patients and also prolonged survival of patients with isolated or multiple metastases. Among the skeletal manifestations the spine is the most often affected site. Using novel imaging techniques with higher resolution and use of metabolic signatures, the screening of cancer patients has improved considerably. Consequently, the diagnosis of metastases is becoming increasingly more sensitive. Therefore, but also due to more effective polychemotherapy protocols, singular or solitary metastases are more frequently observed either in the early stages or as a result of a controlled malignant tumor entity (stable disease). The questions whether a solitary metastasis really exists (illusion or reality?) and its radical oncological and surgical treatment as a circumscribed singular tumor manifestation, is really relevant for the overall prognosis, remains controversial. However, it seems evident that a biologically favorable underlying tumor biology, radical treatment of the primary tumor and a long metastasis-free interval are valid predictors of a good oncological outcome. In the presence of a solitary metastasis under these circumstances (typical example: solitary metastasis of renal cell carcinoma many years after radical tumor nephrectomy) a radical surgical procedure (en bloc spondylectomy) can significantly improve the long-term prognosis of this patient group in combination with adjuvant chemotherapy and/or radiotherapy. However, a thorough evaluation of the overall survival prognosis, a detailed and complete staging followed by a treatment consensus in the interdisciplinary tumor board has to precede any therapeutical decisions.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVE To report results of 4- and 5-level en bloc spondylectomy (EBS) in the treatment of malignant spinal tumors. SUMMARY OF BACKGROUND DATA EBS is widely used to avoid local recurrence in the treatment of spinal malignant tumors. Four- and 5-level EBS are aggressive procedures associated with complications and morbidity. METHODS We conducted a retrospective study of all patients treated with minimum 4-level EBS. Patient and surgical data were noted. Radiographs, magnetic resonance images, and computed tomographic scans were studied for local recurrence, graft, and instrumentation failures at subsequent follow-up. Type of excision was classified into intralesional, marginal, and wide margins. Complications were divided into major or minor and were further classified as intraoperative, early, and late postoperative. At the last follow-up, the patients were classified as alive with no evidence of local or systemic disease, alive with evidence of local or systemic disease or both, dead with evidence of local disease, or systemic disease or both, and dead without evidence of local and systemic disease. RESULTS Nine patients were identified who required a minimum 4-level en bloc resection. Five males and 4 females. Average age was 41.66 years (11-66). There were 8 primary malignant tumors: 3 chordomas, 3 osteosarcomas, 1 chondrosarcoma, 1 primary lung tumor and 1 metastatic alveolar soft part sarcoma. Six were operated with 4-level en bloc and 3 with 5 levels. The mean surgical time was 713 minutes and estimated blood loss was 4.5 L. Mean follow-up was 27.7 months (8-84). At the last follow-up, 6 patients were alive with no evidence of local or systemic disease, 1 alive with evidence of systemic disease, 1 dead with evidence of local disease, or systemic disease or both, and 1 DNLS. Only 1 (11%) patient had a local recurrence. Three patients with Frankel D had full neurological recovery. Histopathological assessment showed marginal margins in 7 patients and wide in 2. There were 9 major and 9 minor complications in 7 patients. Five of 7 patients (71%) with complications, had fully recovered from their complications at the last follow-up. CONCLUSION Multilevel EBS, can be offered to a patient to prevent local recurrence of disease. Even in experienced hands, the risks of intra- and postoperative complications are high (78%). However, most of the patients with complications, recovered completely (71%). Although the surgery itself may prove beneficial, patients should be well informed regarding the morbidity associated with it. LEVEL OF EVIDENCE 4.

Abstract
STUDY DESIGN A retrospective case series. OBJECTIVE To evaluate the long-term effectiveness and problems of total en bloc spondylectomy (TES) for treating metastatic thyroid cancer of the spine. SUMMARY OF BACKGROUND DATA Although TES is indicated for low-grade malignant spinal tumors, its efficacy in treating thyroid cancer metastases in the spine is uncertain. METHODS This study followed 8 patients who underwent TES for spinal metastasis of thyroid cancer (5 males, 3 females; mean age, 55.3 y; mean follow-up period, 6.4 y), 6 with follicular carcinomas and 2 with papillary carcinomas. In 6 patients without a marked paravertebral tumor extension, TES was performed using a posterior approach. Two patients had prominent anterior or anterolateral tumor extension into the thoracic and retroperitoneal cavities, and a combined anterior and posterior approach was used. We evaluated the patients' clinical symptoms, operative procedures, complications, and prognoses. RESULTS Before surgery, the patients' neurological status was evaluated by the Frankel classification (grade C, 4 patients; grade D, 1 patient; grade E, 3 patients) and Tokuhashi scores (9, 1 patient; 11, 2 patients; 13 and 14, 1 patient each; 15, 3 patients). One year after surgery, all the patients had improved by at least a Frankel grade, and 4 patients classified as grade C before surgery had become ambulatory. At the final follow-up (average of 6.4 y), 5 patients had a grade E Frankel classification and 1 had grade D, but 2 patients had suffered neurological deterioration, because of tumor recurrence, at the same level as the TES in one patient and at an adjacent level in the other. At follow-up, all patients were alive; 5 showed no evidence of disease. Two patients experienced rod breakage, at 2.8 and at 3.3 years after TES, and 1 patient suffered an endplate fracture 6 months after TES; this patient developed a late infection, 7 years after TES. CONCLUSIONS TES was effective in controlling spinal thyroid cancer metastasis locally and in preserving the ability to walk. However, instrumentation failure and other late complications arose during the patients' long survival times after TES.

Abstract
A clear consensus has not been established regarding the best treatment for solitary bone metastasis. Here, we reviewed the medical records of patients with a controlled primary malignancy who had only solitary spine metastasis without metastasis to the extraspinal bone or viscera and underwent treatment between April 2007 and December 2012 with stereotactic body radiosurgery using CyberKnife, with a total dose of 24 Gy in three to four fractions. During that time, there were only four cases. This was effective in each case, and all the four patients had no local failure and remained alive at a median follow-up of 68 months (range, 64 to 80 months). Although our experience is limited, this study suggests that stereotactic body radiotherapy could be a feasible, safe, effective, and noninvasive alternative treatment for solitary spine metastasis in patients who are medically inoperable or unsuitable for surgery.

Abstract
OBJECTIVE We report a case of multilevel spondylectomy in which resection and replacement of the adjacent aorta were done. Although spondylectomy is nowadays an established technique, no report on a combined aortic resection and replacement has been reported so far. METHODS The case of a 43-year-old man with a primary chondrosarcoma of the thoracic spine is presented. The local pathology necessitated resection of the aorta. We did a two-stage procedure with resection and replacement of the aorta using a heart-lung machine followed by secondary tumor resection and spinal reconstruction. RESULTS The procedure was successful. A tumor-free margin was achieved. The patient is free of disease 48 months after surgery. CONCLUSION En bloc spondylectomy in combination with aortic resection is feasible and might expand the possibility of producing tumor-free margins in special situations.
