En Bloc Surgery in the Thoracic Spine: Indications, Results, and Complications in a Series of Eighty-Five Patients Affected by Primary and Secondary Malignant Bone Tumors. World Neurosurg 2024; 185:e376-e386. [PMID: 38367855 DOI: 10.1016/j.wneu.2024.02.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 02/03/2024] [Accepted: 02/05/2024] [Indexed: 02/19/2024]
Abstract
BACKGROUND En bloc resection remains the cornerstone treatment for malignant bone tumors affecting the spine. The thoracic spine poses unique challenges because of the proximity of crucial structures. This study assesses outcomes of patients who underwent en bloc spondylectomy for malignant bone tumors at the thoracic level. METHODS We retrospectively reviewed 85 cases of primary and secondary bone tumors in the thoracic spine, undergoing en bloc spondylectomy from 1996 to 2016. Evaluation encompassed clinical presentation, tumor characteristics, surgical outcomes, complications, survival, and recurrence. RESULTS Of 85 patients, 40 presented directly, whereas 45 had undergone previous intralesional surgery. Chondrosarcoma and chordoma comprised the most prevalent primary histologic types; thyroid and kidney carcinomas were the most frequent secondary tumors. Pain was reported in 75 patients at diagnosis. Margins were adequate in 54 cases and intralesional in 31. Immediate postoperative deaths amounted to 4. Major complications included substantial blood loss, neurologic deterioration, and paraplegia. The 5-year local recurrence-free survival was 58.7%, significantly influenced by the surgical margin: patients with wide margins experienced a 5-year local recurrence-free survival of 85.7%, whereas those with marginal and intralesional margins had rates of 56.7% and 45.6%, respectively; overall recurrence was 22.3%, with no notable disparities between previously treated and untreated patients. The 5-year overall survival was 63.2% and 56.2% for primary and secondary tumors, respectively. The overall survival was not significantly influenced by surgical margins. CONCLUSIONS Managing malignant thoracic bone tumors poses significant challenges. This study underscores the criticality of achieving adequate margins, particularly after previous intralesional approaches.

Abstract
INTRODUCTION AND IMPORTANCE Total vertebrectomy En bloc by posterior approach is proposed for primary or secondary single-site malignant tumors of the spine to reduce local recurrence and increase patient survival. This type of surgery is gaining increasing recognition. However, it requires a high level of technical skill and knowledge of the anatomy, physiology and biomechanics of the spine. CASE PRESENTATION We present here a case of a patient with a single thoracic metastasis with neurological deficit treated by total vertebrectomy via the posterior approach, using a cage and pedicle screws in situ. DISCUSSION This surgery is technically demanding, and patient selection therefore requires careful preoperative evaluation. CONCLUSION The reproducibility of the En bloc vertebrectomy method documented in the literature is demonstrated and supported by our case.

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
INTRODUCTION Wide Surgery is the reference treatment for malignant and aggressive benign primary bone tumors in the spine. When located in the lumbar spine, En-Bloc Spondylectomy (EBS) remains a complex challenge. Moreover, surgery is complicated by the presence of the diaphragm in the thoracolumbar junction and the hinderance of the iliac wings at the lumbosacral levels. Therefore, EBS in the lumbar spine frequently requires combined approaches. The purpose of this study is to describe clinical presentation, tumor characteristics and results of a series of 47 consecutive patients affected by malignant primary bone tumors of the lumbar spine who underwent EBS. MATERIALS AND METHODS 47 patients were reviewed. Complications were distinguished in early and late whether they occurred before or after 30 days from surgery. Overall survival (OS), disease-free survival (DFS) and local recurrence-free survival (LRFS) were calculated by the Kaplan-Meier product-limit method from surgery until relapse or death. RESULTS 27 patients presented to observation after a first intralesional approach in a non-specialized center. Chordoma was the most represented histotype. Vertebrectomies were: 23 one-level, 10 two-level, 12 three-level and 2 four-level. Reconstructions were always carried out with screws and rods. The main postoperative complication was blood loss, while hardware failure was the main long-term complication. The 5-year LRFS was 75.5%, the 5-year DFS was 54.3%, and 5-year OS was 63.6%. CONCLUSIONS The surgical margin obtained during the index surgery was statistically associated with Local Recurrence, DFS and OS, underlining the importance of treating patients in reference centers.

Abstract
Despite the recent advances in cancer treatment, the incidence of patients with spinal metastases continues to grow along with the total number of cancer patients. Spinal metastases can significantly impair activities of daily living (ADL) and quality of life (QOL), compared with other types of bone metastases, as they are characterized with severe pain and paralysis caused by skeletal-related events. Reduced ADL can also lead to treatment limitations as certain anticancer agents and radiation therapy are not compatible treatments; thus, leading to a shorter life expectancy. Consequently, maintaining ADLs in patients with spinal metastases is paramount, and spine surgeons have an integral role to play in this regard. However, neurosurgeon, orthopedic and spinal surgeons in Japan do not have a proactive treatment approach to spinal metastases, which may prevent them from providing appropriate treatment when needed (clinical inertia). To overcome such endemic inertia, it is essential for 1) spine surgeons to understand and be more actively involved with patients with musculoskeletal disorders (cancer locomo) and cancer patients; 2) the adoption of a multidisciplinary approach (coordination and meetings not only with the attending oncologist but also with spine surgeons, radiologists, rehabilitation specialists, and other professionals) to preemptive treatment such as medication, radiotherapy, and surgical treatment; and 3) the integration of the latest findings associated with minimally invasive spinal treatments that have expanded the indications for treatment of spinal metastases and improved treatment outcomes. This heralds a new era in the management of spinal metastases.

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.

Abstract
AIM To demonstrate a single posterior approach, total en bloc spondylectomy (TES) could be performed safely without preoperative embolization in spinal metastasis patients. MATERIALS AND METHODS Thirteen solitary spinal metastasis patients (five males) underwent single posterior approach TES at the thoracolumbar spine without preoperative embolization from January 2018 to January 2020. The primary sites were the breast (n = 4), hepatocellular carcinoma (n = 2), colon (n = 2), and others (n = 5). All patients underwent single posterior TES. The Eastern Cooperative Oncology Group, Frankel neurological status, operative time and blood loss, and any complications were all recorded. The patients were regularly followed-up with radiography, computed tomography, and magnetic resonance imaging to detect any local recurrences. RESULTS The mean operative time was 354.6 min, and the mean operative blood loss was 2134.62 ml. None of the patients experienced any perioperative complications. Within the follow-up period (3-24 months), no local recurrences were detected. Two patients (15.38%) were found to have distant metastasis to adjacent and remote vertebrae. Three patients were lost to follow-up, and three patients died of disease. Six patients showed an improved ECOG functional status by at least one grade. Four of Frankel A patients improved their neurological status by at least one grade. CONCLUSION Even without embolization, single posterior TES at the thoracolumbar spine is safe and effective for short-term local control in solitary spinal metastasis. However, TES cannot prevent distant metastasis. Longer-term follow-up studies will be able to further identify the benefits of TES for the long-term local control of diseases.

Abstract
En bloc resection consists in the surgical removal of a vertebral tumor in a single piece with a sufficient margin, to improve survival and reduce recurrence rate. This procedure is technically demanding and correlates with a high complication rate. The purpose of this study is to investigate the risk factors for complications in en bloc resection and evaluate if benefits overcome the risks in term of overall survival. We retrospectively analyzed prospectively collected data of patients treated with en bloc resection between 1980 and 2021. Complications were classified according to SAVES-V2. Overall Survival was estimated using Kaplan-Meier method. A total of 149 patients out of 298 (50%) suffered from at least one complication. Moreover, 220 adverse events were collected (67 intraoperative, 82 early post-operative, 71 late post-operative), 54% of these were classified as grade 3 (in a severity scale from 1 to 6). Ten years overall survival was 67% (95% CI 59-74). The occurrence of relapses was associated to an increased risk of mortality with OR 3.4 (95% CI 2.1-5.5), while complications did not affect the overall survival. Despite a high complication rate, en bloc resection allows for a better control of disease and should be performed in selected patients by specialized surgeons.

J Neurosurg Spine 2022; 37:274-282. [PMID: 35213828 DOI: 10.3171/2022.1.spine21900] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2021] [Accepted: 01/07/2022] [Indexed: 11/06/2022]
Abstract
OBJECTIVE A 3D-printed vertebral prosthesis can be used to reconstruct a bone defect more precisely because of its tailored shape, with its innermost porous structure inducing bone ingrowth. The aim of this study was to evaluate the clinical outcomes of using a 3D-printed artificial vertebral body for spinal reconstruction after en bloc resection of thoracolumbar tumors. METHODS This was a retrospective analysis of 23 consecutive patients who underwent surgical treatment for thoracolumbar tumors at our hospital. En bloc resection was performed in all cases, based on the Weinstein-Boriani-Biagini surgical staging system, and anterior reconstruction was performed using a 3D-printed artificial vertebral body. Prosthesis subsidence, fusion status, and instrumentation-related complications were evaluated. Stability of the anterior reconstruction method was evaluated by CT, and CT Hounsfield unit (HU) values were measured to evaluate fusion status. RESULTS The median follow-up was 37 (range 24-58) months. A customized 3D-printed artificial vertebral body was used in 10 patients, with an off-the-shelf 3D-printed artificial vertebral body used in the other 13 patients. The artificial vertebral body was implanted anteriorly in 5 patients and posteriorly in 18 patients. The overall fusion rate was 87.0%. The average prosthesis subsidence at the final follow-up was 1.60 ± 1.79 mm. Instrument failure occurred in 2 patients, both of whom had substantial subsidence (8.47 and 3.69 mm, respectively). At 3 months, 6 months, and 1 year postoperatively, the mean CT HU values within the artificial vertebral body were 1930 ± 294, 1997 ± 336, and 1994 ± 257, respectively, with each of these values being significantly higher than the immediate postoperative value of 1744 ± 321 (p < 0.05). CONCLUSIONS The use of a 3D-printed artificial vertebral body for anterior reconstruction after en bloc resection of the thoracolumbar spinal tumor may be a feasible and reliable option. The low incidence of prosthesis subsidence of 3D-printed endoprostheses can provide good stability instantly. Measurement of HU values with CT is a valuable method to evaluate the osseointegration at the bone-metal interface of a 3D-printed vertebral prosthesis.

Long-term outcome after en bloc resection and reconstruction of the spinal column and posterior chest wall in the treatment of malignant tumors. J Orthop Sci 2022; 27:899-905. [PMID: 34030940 DOI: 10.1016/j.jos.2021.03.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Revised: 02/21/2021] [Accepted: 03/31/2021] [Indexed: 11/18/2022]
Abstract
BACKGROUND Malignant tumors occurring around both the spinal column and posterior chest wall are uncommon. Surgical resection of chest wall tumors adjacent to the spinal column is still challenging due to the surrounding anatomical structures. The purpose of the present study was to evaluate the long-term outcomes of surgical management in malignant tumors involving the spinal column and posterior chest wall. METHODS Between 1999 and 2007, 10 consecutive patients underwent en bloc resection combined with the posterior chest wall in the treatment of malignant tumors around the spinal column. There were 6 males and 4 females with a mean age at the surgery of 40.9 years old (range, 14-62 years old). The mean postoperative follow-up period was 159.7 months (range, 84-245 months). The clinical history, physical examination, laboratory data, radiological findings, and operative findings for each patient were retrospectively reviewed. RESULTS All surgeries were performed via a combined anterior and posterior approach. The mean numbers of partially resected vertebrae and ribs were 3.1 and 4.1, respectively. Lower or upper lobectomy was performed in four patients, and the diaphragm was partially resected in two patients. The surgical margin was wide in seven patients and marginal in two patients. Although five patients had postoperative respiratory problem, all patients improved immediately without life-threatening complications. There were no patients with respiratory insufficiency after surgery. One patient with osteosarcoma died of lung metastases 99 months after surgery. At the final follow-up, only one patient had local recurrence, five had been continuously disease-free, and three were alive with no evidence of disease. CONCLUSIONS En bloc resection and reconstruction in selected patients with malignant tumors involving both the spinal column and posterior chest wall demonstrated good long-term results for local control and the respiratory function.

Abstract
Objective To translate the original English version of the Spinal Instability Neoplastic Score (SINS) into simplified Chinese, adapt it cross‐culturally, validate its psychometric properties in measuring spinal instability in patients with metastatic spinal tumors in the Chinese mainland, examine the reliability and validity to demonstrate its accuracy and applicability in clinical practice. Methods Patients diagnosed with metastatic spinal disease between January 2016 and January 2020 were recruited. The number of participants was advised to be at least 50 for appropriate analysis of reliability, construct validity, as well as ceiling or floor effects, and recruitment of 100 patients was advised for internal consistency analysis. The study was conducted in two phases: first, the SINS was translated into simplified Chinese; second, the factor structure, internal consistency, test–retest reliability, validity, and floor and ceiling effects of the SC‐SINS were assessed. The internationally recognized cross‐cultural adaptation guidelines were followed. Internal consistency was evaluated with Cronbach's alpha. Test–retest reliability was examined among the patients with a 4‐week interval. The validity of the Chinese version of SINS (SC‐SINS) was assessed by examining its relationship with Kostuik classification. Principal component analysis was conducted to confirm the factor structure of each subscale. Results A total of 160 participants (88 males and 72 females) were enrolled. No major difficulties occurred in the forward and backward translations of SINS. The internal consistency of SC‐SINS was excellent (Cronbach's α =0.857, ranging from 0.68 to 0.85). Test–retest reliability was also excellent with a value of 0.89, ranging from 0.86 to 0.95. Validity analyses indicated that the SC‐SINS was positively and significantly correlated with Kostuik classification. The correlation between “Posterolateral Involvement of Spinal Elements” and “1‐2 Partial Damage” was the highest with a correlation value of 0.792. The correlation between “Pain” and “1–2 Partial Damage” was the lowest with a value of 0.341. All items showed principal component coefficients greater than 0.4. The values of Factor 1 ranged from 0.523 to 0.681; Factor 2 ranged from 0.591 to 0.731; Factor 3 ranged from 0.613 to 0.754; Factor 4 ranged from 0.461 to 0.711; Factor 5 ranged from 0.513 to 0.701; and Factor 6 ranged from 0.501 to 0.668. In addition, neither floor nor ceiling effects were seen in the SC‐SINS. Conclusion The SC‐SINS demonstrated high internal consistency and test–retest reliability, which has been proven valid and reliable to measure spinal stability in patients from the Chinese mainland with metastatic spinal tumor.

Abstract
Background No available meta-analysis has been published that systematically assessed spinal fixation mechanical failure after tumor resection based on largely pooled data. This systematic review and meta-analysis aimed to investigate the spinal fixation failure rate and potential risk factors for hardware failure. Methods Electronic articles published between January 1, 1979, and January 30, 2021, were searched and critically evaluated. The authors independently reviewed the abstracts and extracted data on the spinal fixation failure rate and potential risk factors. Results Thirty-eight studies were finally included in the meta-analysis. The pooled spinal fixation mechanical failure rate was 10%. The significant risk factors for hardware failure included tumor level and cage subsidence. Radiotherapy was a potential risk factor. Conclusion The spinal fixation mechanical failure rate was 10%. Spinal fixation failure is mainly associated with tumor level, cage subsidence and radiotherapy. Durable reconstruction is needed for patients with these risk factors.

Abstract
BACKGROUND En bloc surgery is the mainstay treatment for primary malignant bone tumors, as well as in the cervical spine. Unfortunately, literature on the topic is limited to case reports and small series. METHODS We reviewed all patients affected by primary cervical spine bone tumors treated with en bloc surgeries from 1996 to 2016 and identified 30 eligible cases. We evaluated the clinical presentation and tumor characteristics and reported surgical results, complications, recurrence, and survival rates. RESULTS Only 17 of 30 patients had not been previously treated at presentation. Osteosarcoma and chordoma were the most frequent tumors, and pain was reported in all cases. En bloc spondylectomy, hemispondylectomy, and posterior arch en bloc resection were performed in 16, 12, and 2 patients, respectively. The obtained margin was adequate (wide and marginal) in 60% of cases and intralesional in the remaining cases. Two deaths occurred in the immediate postoperative period. Neurological deterioration, dural tear, and dysphagia were the most frequent complications. The 5-year local recurrence-free survival was 70.4%. The recurrence rate was 38.5% and 11.7% in previously and non-previously treated patients, respectively (χ2: 2.94; P = 0.086). Overall survival at 5 years was 58% and 47% for all series and malignant tumors, respectively. CONCLUSION Primary cervical spine bone tumors present a difficult approach. Findings suggest that patients treated with en bloc surgery show recurrence and survival rates comparable to the same tumors located in the thoracolumbar spine.

Abstract
Objective To investigate the surgical method for primary malignant osseous tumors in the craniovertebral junction (CVJ) and its effectiveness. Methods The clinical data of 7 patients with primary malignant osseous spinal tumors in CVJ, which collected between September 2010 and April 2019, were retrospectively analyzed. There were 5 males and 2 females, aged 23 to 75 years (median, 56 years). All patients were diagnosed as chordoma in 4 cases, plasmacytoma in 2 cases, and fibrosarcoma in 1 case. The disease duration ranged from 0.7 to 36.0 months, with an average of 12.2 months. Lesion location: 1 case of C 0, 1, 3 cases of C 2, 1 case of C 1, 2, 1 case of C 2, 3, and 1 case of C 0-2. Preoperative visual analogue scale (VAS) score was 6.7±2.1, the Japanese Orthopaedic Association (JOA) score was 15.6±2.4. According to American Society of Spinal Cord Injury (ASIA) grading system, there was 1 case of grade C, 1 case of grade D, and 5 cases of grade E. According to Enneking stage of spinal malignant tumor, there was 1 case of stage ⅠB, 2 cases of stage ⅡB, and 4 cases of stage Ⅲ. According to Weinstein-Boriani-Biagini (WBB) stage, there was 1 case of 5-8/A-D, 1 case of 4-9/A-D, 1 case of 6-7/B-D, 1 case of 6-7/A-D, 2 cases of 1-12/A-D, and 1 case of 3-10/A-D. All these patients were treated with tumor extended resection, bone graft fusion, and internal fixation via posterior cervical approach, as well as tumor (stage Ⅰ or stage Ⅱ) boundary resection via transoral or submandibular approach. Meanwhile, anterior reconstructive fusion was procedured with bone grafting Cage needed to place the internal fixation. Results The operation time was 307-695 minutes (mean, 489.57 minutes), and the intraoperative blood loss was 400-2 000 mL (mean, 1 107.14 mL). There was no intraoperative injury in vertebral artery and spinal cord or any related postoperative complications, including incision infection, intracranial infection, and pulmonary infection. All the patients were followed up 3-57 months (mean, 21 months). Postoperative X-ray film and CT showed that the internal fixation screw was firm and in a satisfactory position, and the bone graft was fused at 3-6 months after operation. Symptoms such as neck pain, limb numbness, and fatigue relieved to different degrees after operation. At 3 months after operation, the VAS score improved to 1.7±0.8 ( t=7.638, P=0.000); while the JOA score improved to 16.1±1.5, but no significant difference was found when compared with preoperative score ( t=1.549, P=0.172). According to ASIA grading system, 1 patient with grade C had upgraded to grade D after operation, while the remaining patients had no change. There were 4 cases of recurrence after operation, in which those patients were with high malignancy of tumors before the first surgery. Their tumors also affected a wide range of slope or surrounding soft tissues and could not be completely removed. Among the 4 cases, 1 patient underwent transoral tumor removal operation again, while the other 3 cases gave up further treatment. There was no recurrence among the remaining 3 cases. Conclusion Primary malignant osseous tumors in the CVJ can be completely exercised via means of trabsoral or submandibular approach. Meanwhile the anterior reconstruction can be achieved by placing special Cage specimen. These two methods together with postoperative adjuvant treatments such as radiotherapy and chemotherapy can improve the survival time of patients and reduce tumor recurrence.

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.

Abstract
Our objective is to describe the surgical management and outcomes following surgical intervention for aggressive spine hemangiomas. Patients from 2005 to 2018 with an aggressive hemangioma of the cervical, thoracic, lumbar spine and sacrum treated surgically at a tertiary referral academic medical center were included in this study. The hospital pathology department database was used to identify patients with a diagnosis of aggressive hemangioma. Patient demographics, medical history, operative procedure, adjunct treatment, early and late complications, and recurrence were analyzed using the Fischer exact test with significance set at p < 0.05 Ten patients met inclusion criteria for the study. The average follow up was 11 months. Eight out of ten patients had aggressive hemangioma of the thoracic spine. Seven of the ten patients presented with back or leg pain. The most common surgery was laminectomy at the site of the lesion (70%). 40% of patients underwent a spinal fusion, with two of these patients receiving concurrent intra-operative vertebroplasty. Three patients underwent post-operative radiation therapy. Five complications were noted among three individuals. There were three perioperative complications, deep venous thrombosis, renal insufficiency, one surgical site infection, and two postoperative complications, both revisions. There were no recurrences. Surgical intervention for aggressive spine hemangiomas is an effective treatment with relatively low complication and recurrence rates.

Abstract
STUDY DESIGN Retrospective review of prospectively collected data. OBJECTIVE To evaluate (1) if the segmental resection of the content of the spinal canal could provide an Enneking appropriate tumor-free margin for local control of primary bone tumors surrounding and invading the canal and (2) the safety profile of the segmental resection of the neurostructures. SUMMARY OF BACKGROUND DATA Treatment outcomes of primary malignant and benign aggressive bone tumors of the spine have been dramatically changed by the application of the musculoskeletal oncologic principles described by Enneking. However, the efficacy of spinal oncology surgery might be limited by unique features of spinal anatomy. METHODS Database search was conducted with the following inclusion criteria: en bloc resection, segmental inclusion of the spinal canal content in the surgical specimen, histologically proven diagnosis, minimum follow-up of 2 years. Exclusion criteria were piecemeal excision of the tumor (debulking) and diagnosis other than primary bone tumors (metastasis, or local extension of extraosseous tumors). RESULTS A consecutive cohort of eight patients (three men, five women) was available for review. Two patients died within 3 months from the surgery for systemic disease progression or sequelae of the surgery. En bloc resection with segmental spinal canal content inclusion was able to achieve local control of the disease in four out of remaining six cases (66.7%) at an average follow-up of 68.7 months (range 12-174 mo). Three patients in whom local control was achieved are free from disease at an average follow-up of 98.7 months (range 38-174), and one died for systemic disease progression (after 38 mo). Seven out of 8 patients (87.5%) experienced overall 16 complications. CONCLUSION En bloc resection including the spinal canal content (spinal amputation) to achieve a tumor-free margin might be considered to perform an Enneking appropriate treatment for motivated patients. LEVEL OF EVIDENCE 4.

Abstract
Objectives To summarize the epidemiological characteristics of patients following surgery for spinal metastases retrospectively and make a univariate analysis to identify independent variables that could affect the operation decision making. Methods This was a multicenter retrospective review of patients with spinal metastasis who were treated with surgery from 1 January 2007 to 31 July 2019. Basic clinical data were analyzed retrospectively by univariate analysis to identify independent variables that could affect the decision of operation modalities, including gender, age, spinal metastatic site, Frankel score, Karnofsky performance score (KPS), spinal instability neoplastic score (SINS), visual analogue scale (VAS), Tokuhashi score, urinary and fecal incontinence, spinal pathological fracture, primary tumor, extraspinal metastasis, visceral metastasis, and bone lesion (osteolytic, osteoblastic or mixed). Results A total of 580 patients including 332 males and 248 females were enrolled in the study with an average age of 58.26 years old (range, 13–86 years old). The most common spinal metastatic level was the thoracic vertebra (190 [32.76%]), followed by the lumbar vertebra (146 [25.17%]), cervical vertebra (47 [8.10%]), and sacral vertebra (35 [6.03%]). Metastases involving more than two sites of the cervical, thoracic, lumbar, and sacral vertebrae arose in 162 (27.93%) patients. For primary tumor, there were 198 (34.14%) cases of lung cancer, 41 (7.07%) cases of kidney cancer, 39 (6.72%) cases of breast cancer, 38 (6.55%) cases of gastrointestinal cancer, 35 (6.03%) cases of lymphoma and myeloma, 25 (4.31%) cases of prostate cancer, 24 (4.14%) cases of liver cancer, 23 (3.97%) cases of mesenchymal tissue sarcoma, 20 (3.45%) cases of thyroid cancer, and 84 (14.48%) cases were tumor with unknown origin. Sixty‐three (10.86%) patients received minimally invasive surgery, 460 (79.31%) patients received palliative surgery, and the remaining 57 (9.83%) received tumor resection. According to the univariate analysis, the KPS score, SINS score, VAS score, Tokuhashi score, urinary and fecal incontinence, spinal pathological fracture, and bone lesion (osteolytic, osteoblastic or mixed) were independent and favorable factors affecting the surgery modalities. Conclusions Surgical treatment for spinal metastases was mainly to relieve pain, rebuild spinal stability, improve nerve function, control local tumors, and improve the quality of life of patients. For middle‐aged and elderly patients with good general conditions, severe pain, spinal pathological fracture, spine instability and without urinary and fecal incontinence, early surgical treatment should be actively carried out.

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
STUDY DESIGN Case control series. OBJECTIVE The aim of this study was to evaluate and compare the effectiveness of methods to decrease surgical site infections (SSIs) following spine tumor surgery. SUMMARY OF BACKGROUND DATA With the aging population of the United States, the prevalence of cancer and associated metastatic spine disease is increasing. The most common complication of spine tumor surgery is SSI. METHODS This a single-institution case-control series of patients undergoing spine tumor surgery from June 2003 to October 2018. Patients were grouped into the following groups: Betadine irrigation and intrawound vancomycin powder (BIVP), intrawound vancomycin powder only (IVP), and patients receiving neither (NONE). The primary outcome was SSIs/wound complications. RESULTS One hundred fifty-one spine tumor patients undergoing 174 procedures meeting our inclusion criteria were identified. The BIVP group had 60 patients (73 procedures); the IVP group had 46 patients (47 procedures); and the NONE group had 45 patients (54 procedures). The overall infection rate was 8.6% of all procedures (15/174) and 9.9% (15/151) of all patients. Bivariate analysis comparing patients with and without infections noted the patients with SSIs had significantly higher rates of preoperative radiation treatment (53.3% in infection group vs. 25.5% in noninfection group), P = 0.02. Patients undergoing procedures in the BIVP group had a significantly lower rate of infections (2.7%) than the patients in the IVP (12.8%) and NONE (13%) groups, P = 0.04. Stepwise regression analysis was used to evaluate further factors associated with SSIs. Elevated BMI was significantly associated with SSIs in the model [P = 0.02, odds ratio (OR) 1.14]. BIVP was also protective against infections as compared to the IVP and NONE groups, P = 0.02, OR 0.02. CONCLUSION BIVP led to a significant decrease in SSI rates following spine tumor surgery. Administration of BIVP is not time consuming and decreased SSI rates. LEVEL OF EVIDENCE 3.

Risk Factors for Instrumentation Failure After Total En Bloc Spondylectomy of Thoracic and Lumbar Spine Tumors Using Titanium Mesh Cage for Anterior Reconstruction. World Neurosurg 2019; 135:e106-e115. [PMID: 31756507 DOI: 10.1016/j.wneu.2019.11.057] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Revised: 11/10/2019] [Accepted: 11/11/2019] [Indexed: 11/20/2022]
Abstract
OBJECTIVE The present study investigated the risk factors for instrumentation failure (IF) after total en bloc spondylectomy (TES) of thoracic and lumbar spine tumors using a titanium mesh cage (TMC) for anterior reconstruction. METHODS The data from patients who had undergone TES for thoracic and lumbar spine tumors in our institution were retrospectively reviewed. Anterior reconstruction was performed using a TMC filled with morcelized allograft or morcelized autograft. Posterior reconstruction was performed using pedicle fixation. Survival analysis from TES to IF was conducted. The Kaplan-Meier method was used for univariate analysis. Factors of statistical significance were included in the multivariate analysis using Cox regression analysis. RESULTS A total of 30 patients (20 men and 10 women), with a mean age of 37.1 ± 14.3 years (range, 14-65 years) were included. The mean follow-up period was 41.8 ± 21.3 months (range, 13-120 months). Bone fusion was achieved in 23 patients (76.7%). IF occurred in 8 patients. The mean interval from TES to the first IF was 31.8 ± 15.1 months (range, 13-64 months). On univariable analysis, a body mass index >28 kg/m2, perioperative radiotherapy, and the TMC in an oblique position were associated with IF. On multivariable analysis, these 3 factors were entered into the Cox regression model and were also significant. CONCLUSIONS The use of TES can achieve durable oncological control. However, IF, a not uncommon late complication that leads to reoperation, should be a cause for concern. We found perioperative radiotherapy, a TMC in an oblique position, and a body mass index >28 kg/m2 were significant predictive factors for IF.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVE The purpose of this study was to examine motor and sensory impairments of the lower extremities after L2 nerve root transection during total en bloc spondylectomy (TES) for spinal tumors. SUMMARY OF BACKGROUND DATA At our institute, for TES at L3 to L5 lumbar levels, the nerve roots are preserved. However, at the level of L1 and L2, the vertebral resection and spinal reconstruction via a posterior approach is employed with transection of the nerve roots during dissection and resection of the vertebra. METHODS This study included 13 patients who had undergone TES for spinal tumors involving L2 between 2007 and 2016. Postoperative motor function of the lower extremities was quantified using the Manual Muscle Testing grade for the iliopsoas (IP) and quadriceps femoris (QF) muscles, and a grade of the modified Frankel Classification. Postoperative sensory impairment was quantified by the sites of lower extremity pain and numbness. RESULTS An initial decrease in strength of the IP and QF muscles in more than 60% of the patients, with a decline in the modified Frankel grade in 76.9%, was observed at 1-week after surgery. All patients recovered by the final follow-up, with 12 of the 13 patients walking without a gait aid. The other patient, who had undergone a bilateral dissection of L3 nerve root during TES of L2 and L3, had a mild QF muscle weakness, requiring a cane for walking. Eleven of 13 patients developed pain or numbness in the groin or thigh area after surgery, with the most common area being the anterior aspect of the thigh. CONCLUSION Although IP and QF weakness was observed in the majority of patients who underwent bilateral transection of L2 nerve roots during TES, these deficits recovered over time and did not finally affect activities of daily living.

Abstract
BACKGROUND Relatively few cases of total en bloc spondylectomy (TES) for the L5 tumors have been reported. TES in the lower lumbar region is usually performed through a combined anterior and posterior approach. TES for L5 tumors by a posterior-only approach is technically challenging. CASE DESCRIPTION A 62-year-old woman with persistent pain in her lumbosacral area and lower extremities and numbness of her lateral left lower extremity for 2 months came to our department. She had undergone radical mastectomy 4 years earlier. X-ray and magnetic resonance imaging (MRI) showed that the tumor had destroyed the vertebral body of L5. No other lesions were revealed by emission computed tomography (ECT) or positron emission tomography/computed tomography (PET/CT). With a diagnosis of breast cancer and a solitary metastasis to L5, the patient was treated with posterior-only TES of the L5 tumor and reconstruction. The whole procedure took 10 hours, and her intraoperative blood loss was 9000 mL. The lumbar and leg pain of the patient disappeared postoperatively without serious complications. She started walking 4 weeks after surgery and resumed her daily life. New multiple metastases developed 6 months after surgery, with no sign of local recurrence. Despite active treatment, she died 18 months after surgery. CONCLUSION TES of the L5 tumor can be achieved by a posterior-only approach, with good results and limited complications.

Abstract
Primary and metastatic tumors of the spine represent a significant cause of patient morbidity, and present a management challenge to treating providers. From a neurosurgical standpoint, resection surgery may be warranted in cases of spinal instability, progressive disease, neurological compromise, or intractable symptoms. Removal of a tumor "en bloc" offers a more aggressive modality over more conservative resection techniques. En bloc resection entails the removal of the entirety of a tumor without violation of its capsule, and may offer improved rates of local control and overall survival in appropriately selected patients. Conversely, this technique carries a higher complication rate, and requires a unique set of technical skills as compared to more traditional resection. Here, we describe the technical aspects of en bloc resection, as well as specific indications and considerations when employing this operative technique.

Abstract
OBJECTIVE Ewing sarcoma (ES) is among the most prevalent of bone sarcomas in young people. Less often, it presents as a primary lesion of the spine (5%-15% of patients with ES). METHODS A systematic literature search was performed, querying several scientific databases per PRISMA guidelines. Inclusion criteria specified all studies of patients with surgically treated ES located in the spine. Patient age was categorized into three groups: 0-13 years (age group 1), 14-20 years (age group 2), and > 21 (age group 3). RESULTS Eighteen studies were included, yielding 28 patients with ES of the spine. Sixty-seven percent of patients experienced a favorable outcome, with laminectomies representing the most common (46%) of surgical interventions. One-, 2-, and 5-year survival rates were 82% (n = 23), 75% (n = 21), and 57% (n = 16), respectively. Patients in age group 2 experienced the greatest mortality rate (75%) compared to age group 1 (9%) and age group 3 (22%). The calculated relative risk score indicated patients in age group 2 were 7.5 times more likely to die than other age groups combined (p = 0.02). CONCLUSIONS Primary ES of the spine is a rare, debilitating disease in which the role of surgery and its impact on one's quality of life and independence status has not been well described. This study found the majority of patients experienced a favorable outcome with respect to independence status following surgery and adjunctive treatment. An increased risk of recurrence and death was also present among the adolescent age group (14-20 years).

Abstract
Purpose To obtain a better understanding of the structures around L5 vertebra and provide some anatomical evidence of the feasibility of total en-bloc spondylectomy (TES) on L5 in a posterior-only approach. Methods 12 simulated TESs on L5 by a posterior-only approach were conducted on human cadavers. The distance between the traction point of L4 nerve root and the dural sac (Da), the anterior-posterior diameter of the vertebral body,(Va), the distance between the start point of L4 nerve root and the traction point of L5 nerve root (Dh) and the height of the vertebral body (Vh) were measured. Paired t-test and liner regression were performed to determine the difference and correlation between Da and Va, and between Dh and Vh. The risk of nerve roots or blood vessels damages, and the obstruction caused by iliac wings were evaluated. Results Liner correlations were found between Da and Va, and between Dh and Vh. The regression equations were Da = 0.6673Va + 11.28 and Dh = 1.009Vh + 1.003. There are statistical significant differences between Dh and Vh, and between Da and Va in those whose Va < 34.96 mm. Nerve roots or blood vessels damages and the obstruction caused by iliac wing were able to be avoided. Conclusions If the patient has an anterior-posterior diameter of L5 vertebral body shorter than 34.96 mm, it is possible that the vertebral body can be taken out during TES in a posterior-only approach. Prevention of nerve roots or blood vessels damages, and the obstruction caused by iliac wings are difficulties of this procedure yet not insurmountable. TES on L5 by a posterior-only approach might a possible alternative in treating diseases like L5 vertebral body tumors.

Abstract
BACKGROUND Spinal malignant melanoma (SMM) is a rare type of tumor that can cause nerve roots or spinal cord compression. Patients often suffer from fierce pain and paralyzation. And the estimated survival time were less than 6 months. Surgical interventions to remove the tumor and decompress the nearby nerve roots and spinal cord are effective management. Unfortunately, there lack a thorough and persuasive surgical guideline that specifically aims for this disease. It is necessary to obtain some clinical prognostic factors that predict the recurrence rate and overall survival (OS) of patients with SMM who underwent surgical interventions. METHODS 21 patients with SMM who underwent surgical intervention were retrospectively reviewed. Related patients factors, treatment factors and tumor factors were acquired and subjected into survive analyses using Kaplan-Meier method and the log-rank test. Further Cox proportional hazards model was used to identify independent prognostic factors. Literature regarding surgical interventions on SMM patients were reviewed and summarized as well. RESULTS Surgical approach total en-bloc spondylectomy (TES/Piecemeal) (p = 0.015, B 0.029, 95%CI 0.002-0.508), preoperative Frankel grade (A-C/D-E) (p = 0.021, B 15.041, 95%CI 1.492-151.669) and tumor metastases (Yes/No) (p = 0.013, B 16.667, 95%CI 1.805-153.897) are independent prognostic factors for recurrence free survival (RFS). Preoperative Frankel grade (A-C/D-E) (p = 0.031, B 10.676, 95%CI 1.241-91.877) is independent prognostic factors for OS. 12 literatures have been reviewed, including 11 case reports and one retrospective study. CONCLUSIONS Surgical interventions for patients with SMM are beneficial. Surgical approach (TES/piecemeal), tumor origin (primary/metastasis) and preoperative Frankel grade (A-C/D-E) are independent risk factors in predicting RFS. Preoperative Frankel grade (A-C/D-E) is independent prognostic factor in predicting OS.

Abstract
BACKGROUND Reconstruction of thoracolumbar structural stability is a formidable challenge for spine surgeons after vertebral body tumor resection. Various disadvantages of the currently used expandable or nonexpandable cages have limited their clinical applications. We sought to develop a novel prosthesis for clinical use and assess its preliminary clinical outcome in reconstruction of thoracolumbar structural stability after spinal tumor resection. METHODS Using data obtained from a retrospective analysis of the morphological characteristics of the thoracolumbar vertebrae and endplates in previously reported studies, we modified the nano-hydroxyapatite/polyamide-66 (n-HA/PA66) strut into a novel height-adjustable vertebral body. A retrospective study was performed of 7 patients who had undergone reconstruction of thoracolumbar structural stability with this novel prosthesis from August 2016 to January 2017. RESULTS A novel height-adjustable vertebral body (AHVB) composed of n-HA/PA66 with 2 separate components with a 163° contact surface at each end was manufactured. The height-adjustable range was 28-37 mm. No significant implant-related complications were observed in the process of operation. All patients experienced a significant reduction in pain, with the visual analog scale score decreasing from 7.9 to 4.0. Neurological improvement was assessed using the Frankel grading system after surgery. Postoperative radiographic and computed tomography/magnetic resonance imaging findings indicated that the operated segment was stable, the outcome of kyphosis correction was good, and no prosthesis subsidence or dislocation was observed. CONCLUSION This novel prosthesis has many advantages in the reconstruction of height, lordosis, and alignment after thoracolumbar spinal tumor resection and has a favorable prospect for clinical application.

Abstract
This was a retrospective clinical study.This study aimed to evaluate our institution's experience with total en bloc spondylectomy (TES) in patients treated for primary lumbar spine tumors and investigate postoperative clinical outcomes.TES is a widely accepted by spinal and musculoskeletal surgical oncologists and results in favorable health-related quality of life outcomes. However, this procedure still imposes major risks and complications.The cases of TES performed for primary lumbar spine tumors between 1993 and 2015 were retrospectively analyzed. Primary outcome measures were the rates of perioperative complications and reoperation for instrumentation failure.We enrolled 30 patients (13 men and 17 women; median age and follow-up, 38 years and 87 months, respectively). Three, 7, and 5 cases involved previous radiotherapy, intralesional resection, and chemotherapy, respectively. The most common tumor was giant cell tumor (14 cases) followed by osteosarcoma (4 cases) and plasmacytoma (3 cases). The median estimated blood loss was 1450 mL, and the median operative time was 11 hours. At least 1 perioperative complication occurred in 26 patients (86.7%), with the most common being postoperative muscle weakness (24 patients, 80.0%) followed by surgical site infection and postoperative cerebrospinal fluid leakage (7 patients, respectively; 23.3% each). Revision surgery for instrumentation failure was required in 6 patients (20.0%) at a median of 33 months after the index TES. Four patients experienced local tumor recurrence (13.3%), and their 10-year disease-free rate was 75.0%.TES is a feasible and effective procedure for primary lumbar spine tumors, but the risks of perioperative complications and late instrumentation failure should be acknowledged. Surgical oncologic outcomes were good, especially in patients who underwent TES as their first surgical treatment. Therefore, being familiar with the indications for TES and the surgical technique is important.

Abstract
Background Chordomas are rare malignant tumors of the spinal column often afflicting the upper cervical spine and sacrum. There are few large single center series on chordomas due to its rarity. The purpose of this study is to report a single center's experience with the operative and non-operative management of chordomas. Methods We evaluated our institution's pathology database from 1994 to 2016 to identify patients diagnosed with chordomas. Inclusion criteria were chordomas of the mobile spine and sacrum. Exclusion criteria were chordomas of the clivus and resection performed at another institution. We collected patient demographics as well as the type of resection performed, intra-operative complications, wound complications and recurrence/prognosis. Results We identified 18 patients diagnosed with chordomas at our institution, and 12 met our inclusion criteria. There were four females and eight males with an average age of 64 [32-87] years. All patients were Caucasian and 10 of the 12 had surgery. Of the two patients with sacral chordomas that did not have surgery, one received chemotherapy and the other did not elect for any treatment. One is alive 161 months following diagnosis and the second died 96 months following diagnosis. Five of the lesions were in the mobile spine (one cervical, two thoracic, two lumbar) and seven were in the sacrum. Six patients underwent an en bloc resection [two via total en bloc spondylectomy (TES)]. Average length of follow up is 60 [3-161] months and eight of 12 patients are alive at latest follow up. Intraoperative complications included cardiac arrest, pleural tear, and excessive blood loss (8 L). Two patients, with sacral chordomas, had wound complications. Recurrence occurred in one patient with piecemeal resection and one patient with incomplete resection had post-operative metastatic lesions to the liver and lung. Conclusions We found less recurrence in patients managed with an en bloc resection as opposed to piece meal or intralesional resections. Sacral chordoma patients had higher wound complication rates as compared to chordomas of the mobile spine. The long life expectancy of non-surgically managed patients underscores the indolent nature of chordomas.

Abstract
Due to a worldwide increase of cancer incidence and a longer life expectancy of patients with metastatic cancer, a rise in the incidence of symptomatic vertebral metastases has been observed. Metastatic spinal disease is one of the most dreaded complications of cancer as it is not only associated with severe pain, but also with paralysis, sensory loss, sexual dysfunction, urinary and fecal incontinency when the neurologic elements are compressed. Rapid diagnosis and treatment have been shown to improve both the quality and length of remaining life. This chapter on vertebral metastases with epidural disease and intramedullary spinal metastases will be discussed in terms of epidemiology, pathophysiology, demographics, clinical presentation, diagnosis, and management. With respect to treatment options, our review will summarize the evolution of conventional palliative radiation to modern stereotactic body radiotherapy for spinal metastases and the surgical evolution from traditional open procedures to minimally invasive spine surgery. Lastly, we will review the most common clinical prediction and decision rules, framework and algorithms, and guidelines that have been developed to guide treatment decision making.

Abstract
Background Chordomas are rare malignant primary tumors of the spine. In the mobile spine and sacrum an en-bloc resection is associated with decreased rates of recurrence. Our objective was to identify the top cited articles in chordoma research and to further analyze characteristics of these articles. Methods In March 2017, we used ISI Web of Science (v5.11, Thomas Reuter, Philadelphia, Pennsylvania, USA) to search for the following key word: "chordoma". Articles were searched from 1900 to 2017. Articles were ranked based on number of citations. The results were evaluated to determine articles most clinically relevant to the management of chordomas. The top 50 articles that met the search criteria were further characterized on the basis of: title, author, citation density, journal of publication, year (and decade) of publication, institution and country of origin and paper topic. Results A total of 1,043 articles matched the search criteria. The most influential 50 articles were cited 65 to 290 times. The articles were published between 1926 and 2012, and all articles were published in English. Thirty-three publications (66%) originated from the United States and seven (14%) from Italy. Cancer accounted for the most frequent (n=9) destination journal followed by Journal of Bone and Joint Surgery (n=4). A total of 41 institutions contributed to the top 50 articles. The most common article types were: clinical 44% (n=22), papers that combined clinical and pathology findings 18% (n=9) and basic science research 14% (n=7). Conclusions The top 50 cited articles on chordomas are predominantly clinical papers, arising from the United States and most frequently published in Cancer and Journal of Bone and Joint Surgery.

Abstract
OBJECTIVES The objective of this study is to describe the experience of a Brazilian public university hospital regarding the treatment of metastatic or benign spine lesions with en bloc vertebrectomy of the thoracic and lumbar spines. METHODS This study was a retrospective case series and included all medical records of patients with benign aggressive, primary malignant, or metastatic spine lesions who underwent en bloc vertebrectomy from 2010 to 2015. RESULTS A total of 17 patients were included in the analysis. Most of them (71%) were indicated for surgery based on an oncologic resection for localized disease cure. Overall, 10 of the 17 patients (59%) underwent vertebrectomy via an isolated posterior approach using the technique described by Roy-Camille et al. and Tomita et al., while 7 patients (41%) underwent double approach surgeries. Of the 17 patients who underwent the en bloc resection, 8 are still alive and in the outpatient follow-up (47%), and almost all patients with metastatic lesions (8/9) died. The average survival time following the surgical procedure was 23.8 months. Considering the cases of metastatic lesions and the cases of localized disease (malignant or benign aggressive disease) separately, we observed an average survival time of 15 months and 47.6 months respectively. CONCLUSION This study demonstrates and reinforces the reproducibility of the en bloc vertebrectomy technique described by Tomita et al.

Abstract
Spinal tumors result in high morbidity and a high rate of lower limb paralysis. Both surgical therapy and radiation therapy (RT) are used to treat spinal tumors; however, how best to combine these two therapies to maximize the benefits and minimize the risks is still being debated. It is also difficult to decide the optimal timing, course and dose of RT, especially in pregnant women and children. The aim of this review is to assist surgeons who are dealing with spinal tumors by providing comprehensive information about advanced techniques for administering RT with greater precision and safety, and about the impact of various ways of combining surgery and RT on therapeutic outcomes. We here review published reports about treating spinal tumors with a combination of these two forms of therapy and attempt to draw appropriate conclusions concerning selection of optimal treatment protocols. Our conclusion is that postoperative radiotherapy, especially with high-precision, low-dose and multiple fractions, and brachytherapy are promising therapies to combined with surgery.

Abstract
OBJECTIVE To describe the specific surgical details and report the lessons learned with a series of patients suffering from spinal tumours that underwent total en bloc spondylectomy (TES). METHODS A retrospective case series review is presented, together with an analysis of the clinical and technical variables, as well as the outcomes. RESULTS A total of 10 patients underwent TES (2000-2016) for primary (osteosarcoma, chondrosarcoma, fibrosarcoma and chordoma) and secondary spinal tumours (lung, breast, thyroid, oesophagus, and meningioma metastases). According to the Tomita classification, 2 patients had intra-compartmental tumours, and the rest presented as extra-compartmental. All patients experienced an improvement in their pain level after surgery. Nine patients preserved ambulation post-operatively and one patient developed paraplegia. Six patients needed subsequent operations for wound debridement, tumour recurrence, or revision of the fixation. Other complications included pneumothorax, pleural effusion and venous thrombosis. Four patients remain alive (4 months to 15 years follow-up). The rest died due to primary tumour progression (6.5 months to 12 years). A detailed description of the surgical steps, tips, and pitfalls is provided. Modifications of the technique and adjuncts to resection are commented on. Observation of some considerations (selection of candidates, careful blunt vertebral dissection, strict blood loss control, careful handling of the spinal cord, and maintenance of the radical resection concept at all stages) is key for a successful operative performance. CONCLUSION TES is a paradigmatic operation, in which the concept of radical resection provides functional effectiveness and improves survival in selected patients suffering from spinal tumours. Our preliminary experience allows us to highlight some specific and relevant features, especially those favouring a simpler and safer operation.
