Parasagittal resection of multilevel cervical chordoma with autograft duraplasty and unilateral vertebral artery ligation: A case report and literature review. Radiol Case Rep 2024; 19:1181-1189. [PMID: 38259708 PMCID: PMC10801135 DOI: 10.1016/j.radcr.2023.12.039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Revised: 12/18/2023] [Accepted: 12/20/2023] [Indexed: 01/24/2024] Open
Abstract
Chordomas are rare tumors and the recommended course of treatment typically entails surgical resection, which presents significant challenges owing to the anatomical location commonly involved and the inherent resistance of these lesions to radiation and chemotherapy. This case report details the experience of a 61-year-old male who underwent a parasagittal resection spanning from C1 to C4. A durotomy was executed to enable en bloc excision of the tumor. Subsequently, a duraplasty procedure was implemented, utilizing autologous muscle fascia grafting. A comprehensive analysis of the pertinent literature was conducted to underscore the key clinical aspects and outcomes related to this topic.

Abstract
Introduction and importance Chordoma of the cervical spine is a rare condition associated with poor long-term outcomes. This is mainly attributed to its pathological involvement of vital structures such as the cervical roots and vertebral artery (VA). Although the most appropriate management in these cases is total en bloc excision, attaining complete resection is relatively challenging due to the vicinity of the critical anatomical structures mentioned above. Case description A 15-year-old female with middle cervical spine chordoma was treated by a multidisciplinary team involving neurosurgery and head and neck surgeons utilizing anterior and posterior approaches followed by high-beam X-ray radiotherapy. Histopathological examination matched the description of a chordoma. Fifteen years after the initial excision, the patient maintained her normal neurological function without local recurrence or metastasis. Clinical discussion The patient underwent surgery in two stages. A posterior approach for C3, C4, and C5 laminectomies was performed in the first stage, with the second stage involving head and neck surgery for complete resection of the tumor. The patient also underwent radiotherapy 3 months after surgery for a total duration of 1 month. The patient is currently 30 years old with no evidence of chordoma recurrence. Conclusion Patients afflicted with cervical chordomas often find themselves undergoing multiple operations due to high recurrence rates. Fortunately, the utilization of en bloc resection coupled with adjuvant radiotherapy presents a hopeful treatment modality that can serve to substantially reduce recurrence rates, increase survival rates, and ultimately enhance the quality of life.

Abstract
BACKGROUND Eukaryotic elongation factor 2 kinase (eukaryotic elongation factor 2 kinase, eEF2K) is a calcium calmodulin dependent protein kinase that keeps the highest energy consuming cellular process of protein synthesis under check through negative regulation. eEF2K pauses global protein synthesis rates at the translational elongation step by phosphorylating its only kown substrate elongation factor 2 (eEF2), a unique translocase activity in ekaryotic cells enabling the polypeptide chain elongation. Therefore, eEF2K is thought to preserve cellular energy pools particularly upon acute development of cellular stress conditions such as nutrient deprivation, hypoxia, or infections. Recently, high expression of this enzyme has been associated with poor prognosis in an array of solid tumor types. Therefore, in a growing number of studies tremendous effort is being directed to the development of treatment methods aiming to suppress eEF2K as a novel therapeutic approach in the fight against cancer. METHODS In our study, we aimed to investigate the changes in the tumorigenicity of chordoma cells in presence of gene silencing for eEF2K. Taking a transient gene silencing approach using siRNA particles, eEF2K gene expression was suppressed in chordoma cells. RESULTS Silencing eEF2K expression was associated with a slight increase in cellular proliferation and a decrease in death rates. Furthermore, no alteration in the sensitivity of chordoma cells to chemotherapy was detected in response to the decrease in eEF2K expression which intriguingly promoted suppression of cell migratory and invasion related properties. CONCLUSION Our findings indicate that the loss of eEF2K expression in chordoma cell lines results in the reduction of metastatic capacity.

Abstract
BACKGROUND Wide excision of chordoma provides better local control than intralesional resection or definitive radiotherapy. The en bloc excision of high cervical chordomas is a challenging endeavor because of the complex anatomy of this region and limited reconstructive options. OBSERVATIONS This is the first case report to describe reconstruction with a free vascularized fibular graft following the en bloc excision of a chordoma involving C1-3. LESSONS This report demonstrates the durability of this construct at 10-year follow-up and is the first case report demonstrating satisfactory long-term oncological outcomes after a true margin-negative resection of a high cervical chordoma.

Abstract
BACKGROUND Primary tumors involving the spine are relatively rare but represent surgically challenging procedures with high patient morbidity. En bloc resection of these tumors necessitates large exposures, wide tumor margins, and poses risks to functionally relevant anatomical structures. Augmented reality neuronavigation (ARNV) represents a paradigm shift in neuronavigation, allowing on-demand visualization of 3D navigation data in real-time directly in line with the operative field. METHODS Here, we describe the first application of ARNV to perform distal sacrococcygectomies for the en bloc removal of sacral and retrorectal lesions involving the coccyx in 2 patients, as well as a thoracic 9-11 laminectomy with costotransversectomy for en bloc removal of a schwannoma in a third patient. RESULTS In our experience, ARNV allowed our teams to minimize the length of the incision, reduce the extent of bony resection, and enhanced visualization of critical adjacent anatomy. All tumors were resected en bloc, and the patients recovered well postoperatively, with no known complications. Pathologic analysis confirmed the en bloc removal of these lesions with negative margins. CONCLUSIONS We conclude that ARNV is an effective strategy for the precise, en bloc removal of spinal lesions including both sacrococcygeal tumors involving the retrorectal space and thoracic schwannomas.

Abstract
AbstractEn bloc resection in the spine is performed for both primary and metastatic bone lesions and has been proven to lengthen disease-free survival and decrease the likelihood of local recurrence. It is a complex procedure, which requires a thorough multi-disciplinary approach. This article will discuss the role of the radiologist in characterizing the underlying tumor pathology, staging the tumor and helping to predict possible intraoperative challenges for en bloc resection of primary bone lesions. The postoperative appearances and complications following en bloc resection in the spine will be considered in subsequent articles.

Abstract
Background:
Chordomas are malignant tumors that arise from the remnants of the notochord. Complete en bloc radical resection with postoperative radiation therapy is currently considered the gold standard. Here, we performed a 360-staged approach to manage a C3-C4 chordoma that involved the right vertebral artery.
Case Description:
A 40-year-old woman presented with a C3-C4 chordoma that invaded the right vertebral artery. She responded well to a circumferential approach including resection and stabilization.
Conclusion:
A 40-year-old woman with a C3-C4 spinal chordoma was optimally managed with a combined anterior/posterior surgical approach including decompression/fusion.

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
BACKGROUND Cervicothoracic junction chordomas are uncommon primary spinal tumors optimally treated with en bloc resection. Although en bloc resection is the gold standard for treatment of mobile spinal chordoma, tumor location, size, and extent of involvement frequently complicate the achievement of negative margins. In particular, chordoma involving the thoracic region can require a challenging anterior access, and en bloc resection can lead to a highly destabilized spine. OBSERVATIONS Modern technological advances make en bloc resection more technically feasible than ever before. In this case, the successful en bloc resection of a particularly complex cervicothoracic junction chordoma was facilitated by a multidisciplinary surgical approach that maximized the use of intraoperative computed tomography–guided spinal navigation and patient-specific three-dimensional–printed modeling. LESSONS The authors review the surgical planning and specific techniques that facilitated the successful en bloc resection of this right-sided chordoma via image-guided parasagittal osteotomy across 2 stages. The integration of emerging visualization technologies into complex spinal column tumor management may help to provide optimal oncological care for patients with challenging primary tumors of the mobile spine.

Abstract
OBJECTIVE Tumors of the cervical spine often encase 1 or both vertebral arteries (VA), presenting the treating surgeon with the dilemma of whether to sacrifice or skeletonize the artery. We propose an algorithm for VA management in surgeries for cervical neoplasms METHODS: A retrospective review was carried out of 67 patients undergoing resection of cervical spine tumors with VA involvement. Patients were categorized by tumor origin (primary vs. metastatic) and degree of circumferential VA involvement: 1) abutment only; 2) <180° circumferential involvement; 3) >180° circumferential involvement without complete encasement; or 4) complete encasement. RESULTS Twelve patients (18%) underwent VA sacrifice, whereas 55 (82%) underwent VA skeletonization. Compared with 11/30 patients with primary tumors (37%), only 1/37 patients (3%) with metastatic disease underwent VA sacrifice (P < 0.01). This patient had invasion of the V2 arterial wall, requiring VA sacrifice. Odds of VA sacrifice also increased with increasing circumferential involvement (P < 0.01). No patients with simple abutment or 0°-180° circumferential involvement underwent sacrifice, whereas 6 of 10 (60%) with 180°-359° involvement and 6 of 29 (21%) with complete encasement underwent VA sacrifice. Of the 27 patients with ≥180° involvement, the reasons for preserving the VA were metastatic disease at the time of treatment (n = 18), a compromised contralateral VA (n = 7), vertebrobasilar junction aplasia (n = 1), and presence of a radiculomedullary artery at the affected level (n = 1). CONCLUSIONS Primary tumor disease and >180° of circumferential VA involvement should be considered as indications for intraoperative sacrifice of the VA pending preoperative angiographic evaluation for contraindications.

Abstract
Background Reconstruction following resection of the primary tumors of the upper cervical spine is challenging, and conventional internal implants develop complications in this region. 3D printing, also known as additive manufacturing, can produce patient-specific porous implants in a particular shape for bone defect reconstruction. This study aimed to describe the clinical outcomes of upper cervical spine reconstruction using customized 3D-printed vertebral body in 9 patients with primary tumors involving C2. Methods Patients with primary tumors involving C2 who were treated in our institution between July 2014 and November 2018 were enrolled. A two-stage intralesional spondylectomy was performed using the posterior-anterior approach. Anterior reconstruction was accomplished using a customized 3D-printed vertebral body, which was fabricated by successive layering of melted titanium alloy powder using electron beam melting. No bone graft was used. Results Nine patients (2 males and 7 females) were included in the study with a mean age of 31.4 years (12 to 59 years). Seven patients demonstrated tumors located in C2 and 2 showed involvement of C2 and C3. During a mean follow-up of 28.6 months (range, 12–42 months), 1 patient died of systemic metastasis and 1 had local tumor recurrence, the other 7 patients were alive and functional in their daily living until the last follow-up without evidence of disease. The 3D-printed vertebral bodies were all stable with no sign of displacement or subsidence, evidence of implant osseointegration was observed on the imaging studies. For the posterior instrumentation systems, no screw loosening or rod breakage was found. Conclusions Spinal reconstruction in the upper cervical region using customized 3D-printed vertebral body is reliable. The tailored shape matching with the contact surfaces and the porous structure conductive to osseointegration provide both short- and long-term stability to the implant.

Abstract
BACKGROUND En bloc excision of cervical chordoma is a technically complex procedure, due to the involvement and closeness of the tumor to the spinal cord, cervical nerve roots, and vertebral arteries. Studies have previously shown that en bloc excision of chordomas with negative margins improves local control and prolongs disease-free survival compared with intralesional excision. True en bloc spondylectomy in the cervical spine is not feasible since bilateral vertebral artery sacrifice is not possible. However, for lateralized tumors, en bloc excision of chordoma can be performed with unilateral vertebral artery preservation by parasagittal osteotomy. OBJECTIVE To describe the operative technique of performing en bloc excision of cervical chordoma via parasagittal osteotomy. METHODS Four patients underwent en bloc excision of multilevel cervical chordomas via parasagittal osteotomy between 2008 and 2016. These 4 cases of chordoma were at the upper-cervical, mid-cervical, and cervicothoracic regions. We analyzed the tumor location, oncological staging, surgical technique, and perioperative complications. RESULTS All 4 patients underwent en bloc excision of chordoma with expandable cage reconstruction and posterior instrumentation. Cervical nerve roots were sacrificed in 2 patients, and vertebral artery ligation was performed in 3 patients. Complications include new neurologic deficit, implant failure, and pharyngeal erosion after radiation. No tumor recurrence was seen. CONCLUSION Parasagittal osteotomy is a useful alternative to en bloc spondylectomy in the treatment of lateralized multilevel cervical chordoma, preserving one vertebral artery while still achieving an en bloc resection.

Abstract
PURPOSE To describe the characteristic features of post-carbon-ion radiotherapy (CIRT) vertebral pathological fractures (VPFs) in upper cervical primary malignant spinal tumors (PMSTs) treated by occipito-cervical (OC) fusion. METHODS OC fusion was performed for three consecutive patients with post-CIRT VPFs. The clinical results and imaging findings, including bone single-photon emission computed tomography (SPECT)/CT were prospectively collected. RESULTS No surgery-related wound complication and surgical site infection were noted. One patient experienced re-fracture and displacement of dens with the loosening of occipital screws and was treated by posterior revision surgery. At the final follow-up, all patients were alive without evidence of disease, and the solid OC fusion was confirmed. Bone SPECT/CT clearly revealed the effect of CIRT on bone turnover in the irradiated field. CONCLUSION The OC fusion with autologous bone grafts was a reliable option for the treatment of post-CIRT VPCs in the patients with upper cervical PMSTs. In addition, evaluation of the bone turnover at the irradiated field by bone SPECT/CT would help surgeons select an effective plan of care, such as fusion level and postoperative care.

Spinal dural resection for oncological purposes: a systematic analysis of risks and outcomes in patients with malignant spinal tumors. J Neurosurg Spine 2019; 32:69-78. [PMID: 31628279 DOI: 10.3171/2019.7.spine19477] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2019] [Accepted: 07/24/2019] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Oncological outcomes for many malignant primary spinal tumors and isolated spinal metastases have been shown to correlate with extent of resection. For tumors with dural involvement, some authors have described spinal dural resection at the time of tumor resection in the interest of improving oncological outcomes. The complication profile associated with resection of the spinal dura for oncological purposes, however, and the relative influence of resecting tumor-involved dura on progression-free survival are not well defined. The authors performed a systematic review of the literature and identified cases in which the spinal dura was resected for oncological purposes in the interest of better understanding the associated risks and outcomes of this technique. METHODS Electronic databases (PubMed/MEDLINE, Scopus) were systematically searched to identify studies that reported clinical and/or oncological outcomes of patients with malignant spinal neoplasms undergoing resection of tumor-involved dura at the time of surgical intervention. RESULTS Ten articles describing 15 patients were included in the analysis. The most common tumor histologies were chordoma (3/15, 20%), giant cell tumor (3/15, 20%), epithelioid sarcoma (2/15, 13.3%), osteosarcoma (2/15, 13.3%), and metastasis (2/15, 13.3%). Procedure-related complications were reported in 40% of patients. A trend was seen toward an increased complication rate in redo (66.7%) versus index (16.7%) operations, but this trend did not reach statistical significance (p = 0.24). New, unexpected postoperative neurological deficits were seen in 3 patients (of 14 reporting, 21.4%). A single patient experienced a profound, unexpected neurological deterioration (paraparesis/paraplegia) after surgery, which reportedly improved considerably at latest follow-up. Tumor recurrence was seen in 3 cases (of 12 reporting, 25%) at a mean of 28.34 ± 21.1 months postoperatively. The overall mean radiographic follow-up period was 49.6 ± 36.5 months. CONCLUSIONS Resection of the spinal dura for oncological purposes is rarely performed, although a limited number of reports and small series have demonstrated that it is feasible. Spinal dural resection is primarily performed in patients with isolated, primary spinal neoplasms with an intent to cure. The risk associated with spinal dura resection is nontrivial and the complication profile is significant. The influence of dural resection on oncological outcomes is not well defined, and further study is needed before definitive conclusions may be drawn regarding the oncological benefit of dural resection for any particular patient or pathology.

Abstract
Chordomas are histologically benign tumors with local aggressive behavior. They arise from embryological remnants of the notochord at the clivus, mobile spine, and sacrum. Chordomas are rare tumors in the pediatric age group. Their surgical management is difficult, given their propensity for inaccessible anatomical regions, and proximity to critical neurovascular structures. While en bloc resection with surgical margins has been advocated as the preferred approach for chordomas, tumor characteristics and violation of adjacent anatomical boundaries may not allow for safe en bloc resection of the tumor. Here, the authors present the case of a C1 chordoma in a 5-year-old boy with epidural and prevertebral extension. The patient's treatment consisted of a far-lateral approach for resection of the tumor and C1 arch, followed by circumferential reconstruction of the craniocervical junction with an expandable cage spanning the skull base to C2, and posterior occipitocervical spinal instrumentation. At 42 months after surgery, the patient remains neurologically intact with stable oncological status, and no evidence of craniocervical junction instrumentation failure.

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
STUDY DESIGN A retrospective study. OBJECTIVE To examine the link between major complications, surgical techniques, and perioperative care in the intralesional spondylectomy of the upper cervical spine. SUMMARY OF BACKGROUND DATA Spondylectomy has been demonstrated to prolong cancer-free survival in many patients with locally aggressive spinal tumors. However, the challenging nature of this surgical procedure and the potential for severe complications often limit its application in the upper cervical spine. METHODS Nineteen patients with primary upper cervical tumors were treated with spondylectomy from March 2005 to August 2009, using either the anterior-posterior or posterior-anterior approach. Anterior procedures were transmandibular, transoral, or high retropharyngeal. Anterior reconstructions were performed in plates with iliac crest strut grafts, plates with mesh cages, and Harms mesh cages alone. Occipitocervical fixation was performed with Halo-vest application for postoperative immobilization. RESULTS Vertebral artery injuries occurred unilaterally in 5 cases intraoperatively: 4 occurred in the anterior approach of anterior-posterior procedures. Fusion was achieved in 9 patients with intact internal instrumentation. Fusion with the anterior construct in a tilted position occurred in 3 patients, all of whom underwent anterior-posterior procedures with Halo-vest immobilization for less than 1 month. Nonunion occurred in 3 cases after the posterior-anterior procedure because of anterior bone graft absorption. Prolonged Halo-vest immobilization maintained postoperative stability. Failure of internal instrumentation occurred in 3 cases. Anterior construct dislocation and severe tilting occurred in 2 cases after the anterior-posterior procedure. Five patients had a local recurrence. All recurrent lesions were malignant tumors and occurred in regions where surgical exposure was inadequate with incomplete excision. CONCLUSION The order of the surgical approach is a critical determinant of complications, fusion rates, choice of surgical technique, and reconstruction methods. The postoperative use of a Halo-vest is recommended. Local recurrence is associated with tumor malignancy and inadequate excision margin. LEVEL OF EVIDENCE 4.

Abstract
Chordoma arising from the cervical spine is rare and the traditional long-term prognosis is typically poor. Total en bloc spondylectomy with a wide margin is generally accepted to be the most appropriate management for thoracic and lumbar malignant tumors. However, this method is still challenging for the cervical spine because of the proximity of the tumor to the vertebral arteries and neural elements. Here, we report a 73-year-old man with a C5 vertebral chordoma treated with total piecemeal spondylectomy. Histological examination revealed pathognomonic physaliphorous cells with mucus-filled cytoplasm in the tumor, and the ratio of Ki-67-positive cells within the tumor was high (19.0%), showing active proliferation rate. Local recurrences were found at 9 months, 4 years and 2 months, and 6 years after the initial surgery. All the recurrences were encapsulated and isolated and treated with an additional en bloc resection successfully at each stage. Eight years after the initial total piecemeal spondylectomy, the patient maintained his intact neurological status without local recurrence or metastasis. The prognosis of cervical chordoma depends on the patient's age, surgical procedures, and histological features. In this report, we present that piecemeal spondylectomy is an alternative management for aged patients with cervical chordoma, even for those with high MIB-1 index.

Abstract
BACKGROUND Chordomas arise from remnants of the notochord and occur throughout the neuroaxis. En bloc resection of chordomas can prove especially challenging in the upper cervical spine secondary to the unique structural anatomy and intimate relationship to the vertebral arteries and spinal cord. CASE DESCRIPTION We describe the resection of a C2-C3 chordoma in a 55-year-old woman in 2-stage fashion with preservation of the vertebral arteries. First, a posterior instrumented fusion and removal of the posterior elements was performed, followed by an anterior transmandibular en bloc resection with cage reconstruction with kick-plate support achievable with off-the-shelf products. CONCLUSIONS Chordomas in the upper cervical spine pose a surgical challenge but are amenable to en bloc resection. With careful planning and intraoperative adaptability, the surgeon can achieve a suitable reconstruction with off-the-shelf products.

Abstract
OBJECTIVE To investigate the feasibility and safety of en bloc resection of cervical primary malignant bone tumors by a combined anterior and posterior approach based on a three-dimensional (3-D) printing model. METHODS Five patients with primary malignant bone tumors of the cervical spine underwent en bloc resection via a one-stage combined anteroposterior approach in our hospital from March 2013 to June 2014. They comprised three men and two women of mean age 47.2 years (range, 26-67 years). Three of the tumors were chondrosarcomas and two chordomas. Preoperative 3-D printing models were created by 3-D printing technology. Sagittal en bloc resections were planned based on these models and successfully performed. A 360° reconstruction was performed by spinal instrumentation in all cases. Surgical margins, perioperative complications, local control rate and survival rate were assessed. RESULTS All patients underwent en bloc excision via a combined posterior and anterior approach in one stage. Mean operative time and estimated blood loss were 465 minutes and 1290 mL, respectively. Mean follow-up was 21 months. Wide surgical margins were achieved in two patients and marginal resection in three; these three patients underwent postoperative adjuvant radiation therapy. One vertebral artery was ligated and sacrificed in each of three patients. Nerve root involved by tumor was sacrificed in three patients with preoperative upper extremity weakness. One patient (Case 3) had significant transient radiculopathy with paresis postoperatively. Another (Case 4) with C 4 and C 5 chordoma had respiratory difficulties and pneumonia after surgery postoperatively. He recovered completely after 2 weeks' management with a tracheotomy tube and antibiotics in the intensive care unit. No cerebrovascular complications and wound infection were observed. No local recurrence or instrumentation failure were detected during follow-up. CONCLUSION Though technically challenging, it is feasible and safe to perform en bloc resection of cervical primary bone tumors. This is the most effective means of managing cervical spine tumors. Preoperative 3-D printing modelling enables better anatomical understanding of the relationship between the tumor and cervical spine and can assist in planning the surgical procedure.

Abstract
Aim: This review aimed to summarize the clinical outcomes in relation to tumor resection margins of cervical chordomas. Methods: Studies that described any surgical intervention for cervical chordoma were identified. Cervical chordomas with cranial or spinal extension, purely retropharyngeal chordomas or where resection type was not reported, were excluded from the study. Results: Seventy-six articles were obtained and these reported a total of 195 patients. Seventy-six percent cervical chordoma patients had intralesional resection with adjuvant radiotherapy. Ninety-two percent chordoma recurrences and all chordoma metastases occurred in patients with intralesional resection. En bloc surgeries were longer (900 min vs. 619 min) and staged surgeries. Intralesional surgeries (2899 ml vs. 2661 ml) had greater intraoperative blood loss. Vertebral artery and nerve root sacrifice were greater in en bloc patients (35%, 39%) compared to intralesional patients (17%, 10%). Postoperative complications were more common in en bloc (54%) than in intralesional patients (11%). Conclusions: En bloc resection cervical chordomas are associated with less recurrence and no metastasis compared to intralesional resection. En bloc is possible through wide exposure of the vertebrae via a multidisciplinary team approach and utilization of particular surgical equipment. The higher rate of complications associated with en bloc surgeries may be acceptable, particularly when there is a chance of cure of disease.

Abstract
BACKGROUND AND OBJECTIVE En bloc resections aim at surgically removing a tumor in a single, intact piece. Approach must be planned for the complete removal of the tumor without violation of its margins. The shared knowledge of the morbidity, mortality, risk assessment for local disease recurrence, complications, and death, related to spine tumors excised en bloc could improve the treating physician's apprehension of the diseases and decision making process before, during, and after surgical treatment. The purpose of this study was to review and report the experience gained during 25 years in one of the world's biggest spine oncologic centers. METHODS A retrospective study of prospective collected data of 1681 patients affected by spine tumors, of whom 220 had en bloc resections performed. RESULTS Most tumors were primary-165 cases (43 benign and 122 malignant); metastases occurred in 55 patients. A total of 60 patients died from the disease and 33 local recurrences were recorded. A total of 153 complications were observed in 100 of 216 patients (46.2%); 64 of these patients (30%) suffered 1 complication, whereas the rest had 2 or more. All complications were categorized according to temporal distribution and severity. These were further divided into 7 groups according to the type of complication. There were 105 major and 48 minor complications. Seven patients (4.6%) died as a result of complications. There were 33 local recurrences (15.28%) recorded. Contaminated cases, surgical margins of the resected tumor-intralesional, marginal, and malignant tumors-were statistically significant independent risk factors for local recurrence of the tumor. Contamination, local recurrence, neoadjuvant radiotherapy, number of levels resected, and metastatic tumors compared with primary malignant tumor were shown to be independent risk factors for a patient's death. CONCLUSIONS Treatment of spinal aggressive benign and malignant bone tumors with en bloc resection is beneficial in terms of better local control and prognosis, although it is a highly demanding and risky procedure. Margins are the key point of this procedure, thus a careful preoperative oncologic and surgical staging is necessary to define the optimal surgical approach. The adverse event profile of these surgeries is high. Therefore, it should be performed by experienced and multidisciplinary teams in specialized high volume centers.

Abstract
PURPOSE Identify risk factors, enabling reduction of the rate of complications and improve outcome in en bloc resection surgeries. METHODS A retrospective study of prospective collected data of 1681 patients affected by spine tumors treated from 1990 to 2015 by the same team. RESULTS A total of 220 en bloc resections that were performed on 216 patients during that period. Most of the tumors were primary-165 cases (43 benign and 122 malignant), metastases occurred in 55 cases. Median FU was 45 months (0-371). 153 complications were observed in 100 patients (46.2 %). 64 (30 %) suffered one complication, while the rest had two or more. There were 105 major and 48 minor complications. Seven patients (4.6 %) died as a result of complications. The combined approach, neoadjuvant chemotherapy and neoadjuvant radiotherapy were statistically significant independent risk factors for complications occurrence. 33 patients (15.2 %) suffered from local recurrence. Reoperations were mostly due to tumor recurrences, but also to hardware failures, wound dehiscence, hematomas and aortic dissection. CONCLUSION The rate of complication is higher in multisegmental resections and when double combined approach is performed. Reoperations display greater morbidity owing to dissection through scar/fibrosis from previous operations and possibly from RT. Careful treatment planning and, in the event of uncertainty, referral to a specialty center must be stressed. The high risk of complications should not discourage surgeons from performing en bloc resection when needed. Most of the patients who sustain complications benefit from the better local control resulting from en bloc resection.

Abstract
INTRODUCTION En bloc resection of high-cervical chordomas is a technically challenging procedure associated with significant morbidity. Two key components of this procedure include the approach and the method of spinal reconstruction. A limited number of reported cases of en bloc resection of high-cervical chordomas have been reported in the literature. CASE PRESENTATION We report a novel case using an expandable cage to reconstruct the anterior spinal column above C2 with fixation to the clivus. We also report a novel anterior approach to the high-cervical spine via a midline labiomandibular glossotomy. We detail the management of complications related to 2 instances of wound dehiscence and hardware exposure requiring two additional operations. The final surgical procedure involved explantation of the anterior cervical plate and use of a vascularized radial graft to close the posterior pharyngeal defect and protect the hardware. At 26-month follow-up, the patient remained disease free without any neurologic deficit. DISCUSSION We report the novel use of the midline labiomandibular glossotomy for surgical approach and reconstruction of the anterior column to the clivus with an expandable cage. The unique features of this operative strategy allowed the surgical team to tailor the construct intraoperatively, resulting in solid arthrodesis without significant neurologic sequelae. CONCLUSIONS Labiomandibular glossotomy for approach to high anterior cervical chordomas followed by craniospinal reconstruction to the clivus with an expandable cage represents a novel technique for managing high cervical chordomas.

Abstract
Chordoma is a locally aggressive malignant tumor that generally occurs in the clivus, mobile spine and sacrum. While en bloc resection with wide margins has been advocated as the only cure for chordomas, tumor characteristics and violation of critical anatomical boundaries may preclude pursuing this treatment option in the cervical spine. We present a C2 chordoma in a 35-year-old man with epidural and prevertebral extension that was treated with a single stage anterior-posterior total C2 spondylectomy with novel reconstruction using an expandable cage with integrated fixation followed by stereotactic radiosurgery. Single stage intralesional total C2 spondylectomy via anterior transoral and posterior approaches was performed. The anterior column was reconstructed using an expandable cage with integrated fixation from the clivus to C3. The patient maintained his intact neurological status at 6 month follow-up with full resumption of activities of daily living without any significant morbidity.

Abstract
Background: Recently, en bloc spondylectomy for upper cervical chordomas has been reported. Most authors utilize the combined approaches (e.g., transoral tumor resection with anterior column reconstruction and primary pharyngeal closure without up-front flap repair). However, the 60% incidence of posterior pharyngeal wall dehiscence delays oral intake, typically requires an additional surgery (e.g. free-flap), and delays radiation therapy. Methods: Here, we demonstrate the efficacy of en bloc C2–C3 spondylectomy for the treatment of upper cervical chordomas utilizing a combined transoral followed by posterior approach. We used a novel anterior de-epithelialized submental island flap (SIF) as an underlay graft between the pharyngeal wall and cage/hardware to prevent pharyngeal wound dehiscence. Results: Despite a small pharyngeal fistula, the construct healed and the patient was disease-free 40 months later. Conclusion: En bloc C2–C3 spondylectomy for the treatment of an upper cervical chordoma typically requires a combined transoral and posterior approaches. This required utilization of an anterior SIF to promote adequate wound healing. This maneuver avoided incurring the typical complications of combined approaches (e.g. transoral tumor resection with anterior column reconstruction and primary pharyngeal closure without up-front flap repair).

Abstract
Chordomas are one of the rarest bone tumors, and they originate from remnants of embryonic notochord along the spine, more frequently at the skull base and sacrum. Although they are relatively slow growing and low grade, chordomas are highly recurrent, aggressive, locally invasive, and prone to metastasize to the lungs, bone, and the liver. Chordomas highly and generally show a dual epithelial-mesenchymal differentiation. These tumors resist chemotherapy and radiotherapy; therefore, radical surgery and high-dose radiation are the most used treatments, although there is no standard way to treat the disease. The molecular biology process behind the initiation and progression of a chordoma needs to be revealed for a better understanding of the disease and to develop more effective therapies. Efforts to discover the mysteries of these molecular aspects have delineated several molecular and genetic alterations in this tumor. Here, we review and describe the emerging insights into the molecular landscape of chordomas.

Abstract
OBJECT Recently, aggressive surgical techniques and a push toward en bloc resections of certain tumors have resulted in a need for creative spinal column reconstruction. Iatrogenic instability following these resections requires a thoughtful approach to adequately transfer load-bearing forces from the skull and upper cervical spine to the subaxial spine. METHODS The authors present a series of 7 cases in which lateral mass reconstruction with a cage or fibular strut graft was used to provide load-bearing support, including 1 case of bilateral cage placement. RESULTS The authors discuss the surgical nuances of en bloc resection of high cervical tumors and explain their technique for lateral mass cage placement. Additionally, they provide their rationale for the use of these constructs throughout the craniocervical junction and subaxial spine. CONCLUSIONS Lateral mass reconstruction provides a potential alternative or adjuvant method of restoring the load-bearing capabilities of the cervical spine.

Abstract
Object
Chordomas involving the mobile spine are ideally managed via en bloc resection with reconstruction to optimize local control and possibly offer cure. In the cervical spine, local anatomy poses unique challenges, limiting the feasibility of aggressive resection. The authors present a multi-institutional series of 16 cases of cervical chordomas removed en bloc. Particular attention was paid to clinical outcome, complications, and recurrence. In addition, outcomes were assessed according to position of tumor at the C1–2 level versus the subaxial (SA) spine (C3–7).
Methods
The authors reviewed cases involving patients who underwent en bloc resection of cervical chordoma at 4 large spine centers. Patients were included if the lesion epicenter involved the C-1 to C-7 vertebral bodies. Demographic data and details of surgery, follow-up course, exposure to adjuvant therapy, and complications were obtained. Outcome was correlated with presence of tumor in C1–2 versus subaxial spine via a Student t-test.
Results
Sixteen patients were identified (mean age at presentation 55 ± 14 years). Seven cases (44%) cases involved C1–2, and 16 involved the subaxial spine. Median survival did not differ significantly different between the C1–2 (72 months) and SA (60 months) groups (p = 0.65). A combined (staged anteroposterior) approach was used in 81% of the cases. Use of the combined approach was significantly more common in treatment of subaxial than C1–2 tumors (100% vs 57%, p = 0.04). En bloc resection was attempted via an anterior approach in 6% of cases (C1–2: 14.3%; SA: 0%; p = 0.17) and a posterior approach in 13% of cases (C1–2: 29%; SA: 0%; p = 0.09). The most commonly reported margin classification was marginal (56% of cases), followed by violated (25%) and wide (19%). En bloc excision of subaxial tumors was significantly more likely to result in marginal margins than excision of C1–2 tumors (C1–2: 29%; SA: 78%; p = 0.03). C1–2 tumors were associated with significantly higher rates of postoperative complications (C1–2: 71%; SA: 22%; p = 0.03). Both local and distant tumor recurrence was greatest for C1–2 tumors (local C1–2: 29%; local SA: 11%; distant C1–2: 14%; distant SA: 0%). Statistical analysis of tumor recurrence based on tumor location was not possible due to the small number of cases. There was no between-groups difference in exposure to postoperative adjuvant radiotherapy. There was no difference in median survival between groups receiving proton beam radiotherapy or intensity-modulated radiotherapy versus no radiation therapy (p = 0.8).
Conclusions
Compared with en bloc resection of chordomas involving the subaxial cervical spine, en bloc resection of chordomas involving the upper cervical spine (C1–2) is associated with poorer outcomes, such as less favorable margins, higher rates of complications, and increased tumor recurrence. Data from this cohort do not support a statistically significant difference in survival for patients with C1–2 versus subaxial disease, but larger studies are needed to further study survival differences.

Abstract
PURPOSES To review in the literature, all the epidemiological, clinical, radiological, histological and therapeutic data regarding chordomas as well as various notochordal entities: ecchordosis physaliphora, intradural and intraparenchymatous chordomas, benign notochordal cell tumors, parachordomas and extra-axial chordomas. To identify different types of chordomas, including familial forms, associations with tuberous sclerosis, Ollier's disease and Maffucci's syndrome, forms with metastasis and seeding. To assess the recent data regarding molecular biology and progress in targeted therapy. To compare the different types of radiotherapy, especially protontherapy and their therapeutic effects. To review the largest series of chordomas in their different localizations (skull base, sacrum and mobile spine) from the literature. MATERIALS The series of 136 chordomas treated and followed up over 20 years (1972-2012) in the department of neurosurgery at Lariboisière hospital is reviewed. It includes: 58 chordomas of the skull base, 47 of the craniocervical junction, 23 of the cervical spine and 8 from the lombosacral region. Similarly, 31 chordomas in children (less than 18 years of age), observed in the departments of neurosurgery of les Enfants-Malades and Lariboisière hospitals, are presented. They were observed between 1976 and 2010 and were located intracranially (n=22 including 13 with cervical extension), 4 at the craniocervical junction level and 5 in the cervical spine. METHODS In the entire Lariboisière series and in the different groups of localization, different parameters were analyzed: the delay of diagnosis, of follow-up, of occurrence of metastasis, recurrence and death, the number of primary patients and patients referred to us after progression or recurrence and the number of deaths, recurrences and metastases. The influence of the quality of resection (total, subtotal and partial) on the prognosis is also presented. Kaplan-Meier actuarial curves of overall survival and disease free survival were performed in the entire series, including the different groups of localization based on the following 4 parameters: age, primary and secondary patients, quality of resection and protontherapy. In the pediatric series, a similar analysis was carried-out but was limited by the small number of patients in the subgroups. RESULTS In the Lariboisière series, the mean delay of diagnosis is 10 months and the mean follow-up is 80 months in each group. The delay before recurrence, metastasis and death is always better for the skull base chordomas and worse for those of the craniocervical junction, which have similar results to those of the cervical spine. Similar figures were observed as regards the number of deaths, metastases and recurrences. Quality of resection is the major factor of prognosis with 20.5 % of deaths and 28 % of recurrences after total resection as compared to 52.5 % and 47.5 % after subtotal resection. This is still more obvious in the group of skull base chordomas. Adding protontherapy to a total resection can still improve the results but there is no change after subtotal resection. The actuarial curve of overall survival shows a clear cut in the slope with some chordomas having a fast evolution towards recurrence and death in less than 4 years and others having a long survival of sometimes more than 20 years. Also, age has no influence on the prognosis. In primary patients, disease free survival is better than in secondary patients but not in overall survival. Protontherapy only improves the overall survival in the entire series and in the skull base group. Total resection improves both the overall and disease free survival in each group. Finally, the adjunct of protontherapy after total resection is clearly demonstrated. In the pediatric series, the median follow-up is 5.7 years. Overall survival and disease free survival are respectively 63 % and 54.3 %. Factors of prognosis are the histological type (atypical forms), localization (worse for the cervical spine and better for the clivus) and again it will depend on the quality of resection. CONCLUSIONS Many different pathologies derived from the notochord can be observed: some are remnants, some may be precursors of chordomas and some have similar features but are probably not genuine chordomas. To-day, immuno-histological studies should permit to differentiate them from real chordomas. Improving knowledge of molecular biology raises hopes for complementary treatments but to date the quality of surgical resection is still the main factor of prognosis. Complementary protontherapy seems useful, especially in skull base chordomas, which have better overall results than those of the craniocervical junction and of the cervical spine. However, we are still lacking an intrinsic marker of evolution to differentiate the slow growing chordomas with an indolent evolution from aggressive types leading rapidly to recurrence and death on which more aggressive treatments should be applied.

Abstract
En bloc resection of cervical chordomas has led to longer survival rates but has resulted in significant morbidities from the procedure, especially when the tumor is multilevel and located in the high-cervical (C1–3) region. To date, there have been only 5 reported cases of multilevel en bloc resection of chordomas in the high-cervical spine. In this technical report the authors describe a sixth case. A complete spondylectomy was performed at C-2 and C-3 with spinal reconstruction and stabilization, using several new modalities that were not used in the previous cases. The use of 1) preoperative endovascular sacrificing of the vertebral artery, 2) CT image-guidance, 3) an ultrasonic aspirator for skeletonizing the vertebral artery, and 4) the custom design of an anterior cage all contributed to absence of intraoperative or long-term (20 months) hardware failure and pseudarthrosis.

Abstract
OBJECT The object of this investigation was to conduct a morphometric study in cadavers to determine anatomical structures, their relationships, and their morphometry for subaxial cervical spondylectomy. METHODS Forty sides of 20 cadavers were used for this study. Dissections were performed in 2 stages (anteriorly and posteriorly). Twenty-one morphometric measurements were performed for both sides of the C3-6 vertebrae. Data were analyzed statistically. RESULTS Morphometry of the laminas, tuberculum posterius, pedicle, corpus, foramen transversarium, and processus costalis were measured. CONCLUSIONS Detailed quantitative anatomical knowledge for operations requiring wide dissection and resection, such as cervical spondylectomy, lowers the morbidity rate.

Abstract
PURPOSE To study the anatomic parameters related to clival screw and establish reference data concerning the craniovertebral fixation technique. METHODS Morphometric measurement of the clivus and the surrounding anatomic structures were obtained on 41 dry bone specimens. Then, 2-D CT reconstruction of the craniovertebral region of 30 patients (19 men and 11 women, ranging in age from 20-64 years with an average age of 38.8 years) were performed to measure the safety range for a 3.5-mm screw placement. Nine entry points were evaluated. Finally, one male fresh cadaver specimen (age 46 years) was dissected to observe the craniovertebral region. RESULTS The clivus faces the basilar artery, the V ~ XII cranial nerves, the pons, and ventral medulla oblongata at its intracranial surface. The longitudinal diameter of extracranial clivus was 25.87 ± 2.64 mm. The narrowest diameter of the clivus was 12.84 ± 1.08 mm, the distance between the left and right hypoglossal canal was 32.70 ± 2.09 mm at its widest part. The distance between the left and right structures, the maximum value was 49.31 ± 4.16 mm at carotid canal, the minimum value was 16.54 ± 2.04 mm at the occipital condyle. The measurement of clival screws placement simulation via 2-D CT reconstruction images shows the maximum upper insertion angle of three components the optimal entry points, the candidate points, the limit entry points was 130.19°, 125.23° and 85.72°, and the total mean screw length was 7.57, 10.13 and 15.6 mm at the vertical entry angle, respectively. CONCLUSIONS Clival screw placement is a viable option for craniovertebral fixation. There is a safe scope for the screw length and angle of the screw placement. And, these parameters obtained in the present study will be helpful for anyone contemplating the use of clival screw fixation.

Abstract
OBJECT Cervical chordomas are rare lesions and usually bring about challenges in treatment planning because of their wide extension and complicated adjacent anatomy. There are few large published series at present focusing on cervical chordomas. The authors studied a consecutive series of 14 patients with primary cervical chordomas who underwent surgical treatment and were observed between 1989 and 2008. By reviewing the clinical patterns and follow-up data, they sought to investigate the clinical characters, tailor the appropriate surgical techniques, and establish prognosis factors for cervical chordomas. METHODS Hospitalization and follow-up data in the 14 patients were collected. All patients underwent piecemeal tumor excision and reconstruction for stability; total spondylectomy was achieved in 5 cases. Postoperative radiotherapy was administered in all patients. Kaplan-Meier plots were used to represent tumor recurrence and patient survival, and log-rank testing was used to determine the risk factors of local recurrence. RESULTS Follow-up ranged from 8 to 120 months (mean 58.6 months). Symptom and neural status in most patients improved after surgery. The 1- and 5-year disease-free survival rates were 78.6% and 50%, respectively, and the 1- and 5-year survival rates were 92.9% and 85.7%, respectively. Log-rank tests revealed that the following variables were significantly associated with a high rate of tumor recurrence: age less than 40 years or greater than 70 years (p = 0.006) and an upper cervical tumor location (p = 0.019). CONCLUSIONS Chordomas in the cervical spine are usually neoplasms that exhibit insidious growth and a wide extension by the time of diagnosis. Radical intralesional debulking surgery and postoperative radiotherapy have been effective treatment. A limited application of en bloc tumor resection and the highly likely intraoperative intralesional tumor seeding may partially explain the high local recurrence rate, whereas the chance of distant metastases, fortunately, is very low. Most recurrence were documented within 3 years. Some specific surgical techniques should be emphasized to minimize tumor seeding. Patients with upper cervical chordomas, younger adults, and elderly adults have worse prognosis. For patients with chordoma extending to both the anterior and posterior spinal columns, total spondylectomy combined with piecemeal excision is recommended for a better prognosis.

Abstract
STUDY DESIGN Retrospective case series of five consecutive patients. OBJECTIVE To determine the oncological outcomes and morbidity rates after en bloc excisions of cervical chordomas. SUMMARY OF BACKGROUND DATA Studies have demonstrated that en bloc surgical excision of chordoma with negative margins results in improved local disease control and survival compared with intralesional resections. Chordomas arising from the cervical spine are rare and they present unique challenges for en bloc tumor excision. We present a series of five consecutive cases of cervical chordoma managed with en bloc tumor excision, which represents one of the largest surgical experiences of cervical chordomas reported to date. METHODS A retrospective review of our institutional spine tumor database identified five consecutive patients who underwent en bloc tumor excision for cervical spine chordoma from 2000 to 2007. We analyze their surgical margins, perioperative complications, tumor recurrence rate, and survival. RESULTS Our review demonstrated that dysphagia and cervicalgia were the most common presenting symptoms for cervical chordoma. The mean age of diagnosis in this cohort was 52.4 years and our mean follow-up is 54.7 months. All five patients required multistage procedures to achieve en bloc tumor excision. Independent analysis of the surgical margins by the pathologists revealed that marginal en bloc excisions were achieved in all five patients. Our 30-day perioperative complication was significant for one case of transient radiculopathy with paresis and one wound infection. Other long-term complications included three cases with pseudoarthrosis with instrumentation failures requiring surgical revisions. There were no neurological or cerebrovascular complications. The mean disease-free survival after en bloc spondylectomy for cervical chordoma was 84.2 months in this cohort. CONCLUSION En bloc excision of chordoma, whether wide or marginal, is the most ideal for treatment to prolong disease-free survival. En bloc excisions of chordomas in the cervical spine are technically complex procedures but can be performed with acceptable safety and perioperative morbidity.

Abstract
STUDY DESIGN A primary leiomyosarcoma located on the left side of the C2 is reported. Left-sided partial spondylectomy and anterior reconstruction with posterior stabilization was performed by a two-staged operation. OBJECTIVE To emphasize the occurrence of primary leiomyosarcoma and the importance of proper stabilization in the upper cervical spine. SUMMARY OF BACKGROUND DATA Leiomyosarcoma is a rare malignant neoplasm of the bone and the primary leiomyosarcoma of the spine is extremely rare. Radical tumor excision is the goal in case of vertebral leiomyosarcoma, but to both gain surgical access to the upper cervical spine and obtain anterior reconstruction is challenging. METHODS Leiomyosarcoma of the C2 in a 25-year-old woman with mild neurologic deficits is reported. A left-sided partial spondylectomy of C2 was performed. The defect of the vertebral body was reconstructed by expandable titanium prosthesis, and posterior craniocervical fixation was performed by the polyaxial screws in the lateral masses and rod/plates. RESULTS The surgical margin was very small. The pathology of the tumor was reported as leiomyosarcoma. No sign of local recurrence or metastasis was evident 1 year after surgery. CONCLUSION Leiomyosarcoma, although rare, should be kept in mind as one of the possible diagnoses when a patient with an upper cervical tumor is presented and complete tumor removal must be the goal.

Abstract
Abstract
BACKGROUND
The efficacy of en bloc resection for spinal tumors is unknown because most of the current evidence is provided by small, single-institution clinical series or case reports.
OBJECTIVE
To combine all previously published reports of en bloc resection for primary and metastatic spinal tumors, to describe the overall pattern of disease-free survival, and to investigate potentially prognostic factors for recurrence.
METHODS
A complete MEDLINE search for all articles reporting survival data for en bloc resection of spinal tumors was undertaken; 44 articles met inclusion criteria from which 306 eligible patients were identified.
RESULTS
There were 229 cases of primary tumors with a mean follow-up of 65.0 months and 77 cases of solitary metastatic tumors with a mean follow-up of 26.5 months. Median time to recurrence was 113 months for the primary group and 24 months for the metastatic group. Disease-free survival rates at 1, 5, and 10 years were 92.6%, 63.2%, and 43.9%, respectively, for the primary group and 61.8%, 37.5%, and 0%, respectively, for the metastatic group; 5-year disease-free survival rates were 58.4% for chordoma and 62.9% for chondrosarcoma. After adjusting for covariates, age, male sex, metastatic tumors, and osteosarcomas were significantly associated with a tumor recurrence.
CONCLUSION
This study provides the largest published series of patients undergoing en bloc resection for spinal tumors. Median time to recurrence reached almost 10 years in patients with primary tumors; however, it was only 2 years in those with isolated metastatic tumors.

Abstract
Object
Primary spine tumors frequently involve the C-2 vertebra. Complete resection of the lesion may require total removal of the C-2 vertebral body, pedicles, and dens process. Authors of this biomechanical study are the first to evaluate a comprehensive set of reconstruction methods after C-2 resection to determine the optimal configuration depending on the degree of excision required.
Methods
Eight human heads (from the skull to C-6) from 4 males and 4 females with a mean age of 68 ± 18 years at death were cleaned of tissue, while leaving ligaments and discs intact. Nondestructive flexion and extension (FE), lateral bending (LB), and axial rotation (AR) tests were conducted using a nonconstraining, pure moment loading apparatus, and relative motion across the fusion site (C1–3) was measured using a 3D motion tracking system. Specimens were tested up to 1.5 Nm at 0.25-Nm intervals for 45 seconds each. The spines were instrumented using 3.5-mm titanium rods with a midline occipitocervical plate (4.0 × 12–mm screws) and lateral mass screws (excluding C-2) at the C-1 (3.0 × 40 mm) and C3–5 levels (3.0 × 16 mm). Testing was repeated for the following configurations: Configuration 1 (CF1), instrumentation only from occiput to C-5; CF2, C-2 corpectomy leaving the dens; CF3, titanium mesh cage (16-mm diameter) from C-3 to C-1 ring and dens; CF4, removal of cage, C-1 ring, and dens; CF5, titanium mesh cage from C-3 to clivus (16-mm diameter); CF6, removal of C-2 posterior elements leaving the C3–clivus cage (spondylectomy); CF7, titanium mesh cage from C-3 to clivus (16-mm diameter) with 2 titanium mesh cages from C-3 to C-1 lateral masses (12-mm diameter); and CF8, removal of all 3 cages. A crosslink was added connecting the posterior rods for CF1, CF6, and CF8. Range-of-motion (ROM) differences between all groups were compared via repeated-measures ANOVA with paired comparisons using the Student t-test with a Tukey post hoc adjustment. A p < 0.05 indicated significance.
Results
The addition of a central cage significantly increased FE rigidity compared with posterior instrumentation alone but had less of an effect in AR and LB. The addition of lateral cages did not significantly improve rigidity in any bending direction (CF6 vs CF7, p > 0.05). With posterior instrumentation alone (CF1 and CF2), C-2 corpectomy reduced bending rigidity in only the FE direction (p < 0.05). The removal of C-2 posterior elements in the presence of a C3–clivus cage did not affect the ROM in any bending mode (CF5 vs CF6, p > 0.05). A crosslink addition in CF1, CF6, and CF8 did not significantly affect primary or off-axis ROM (p > 0.05).
Conclusions
Study results indicated that posterior instrumentation alone with 3.5-mm rods is insufficient for stability restoration after a C-2 corpectomy. Either C3–1 or C3–clivus cages can correct instability introduced by C-2 removal in the presence of posterior instrumentation. The addition of lateral cages to a C3–clivus fusion construct may be unnecessary since it does not significantly improve rigidity in any direction.

Abstract
Chordomas are rare tumors that arise from the sacrum, spine, and skull base. Surgical management of these tumors can be difficult, given their locally destructive behavior and predilection for growing near delicate and critical structures. En bloc resection with negative margins can be difficult to perform without damaging adjacent structures and causing significant clinical morbidity. For chordomas of the upper cervical spine, surgical options traditionally involve transoral or submandibular approaches. The authors report the use of the image-guided, endoscopic, transcervical approach to the upper cervical spine as an alternative to traditional techniques for addressing upper cervical spine tumors, particularly for tumors where gross-total resection is not feasible.

Abstract
STUDY DESIGN This illustrative case report is designed to provide technical data regarding the use of a posterior approach to resect a retropharyngeal chordoma involving the craniovertebral junction. OBJECTIVE The objective of this report is to emphasize the utility of the posterior approach when treating anterior tumors of the craniovertebral junction. SUMMARY OF BACKGROUND DATA Traditionally, a transoral transpharyngeal or extended anterior approach was used to resect anterior tumors of the craniovertebral junction. These approaches have several limitations unique to these exposures, limitations not applicable to a posterior midline cervical approach. METHODS A case report is provided that illustrates the use of a posterior cervical approach used to resect a retropharyngeal craniovertebral junction chordoma. RESULTS Gross total resection of a retropharyngeal chordoma was achieved using a posterior cervical approach. Although local tumor recurrence did occur, this was resected and adjuvant radiotherapy prescribed. This resulted in an ongoing 4-year recurrence free survival. CONCLUSIONS The posterior cervical midline exposure could be used to dissect and remove anterior retropharyngeal tumors, with minimal morbidity.

Abstract
STUDY DESIGN Systematic review and ambispective multicenter cohort study. OBJECTIVE 1. To compare the effects of wide/marginal (en bloc) resection with intralesional resection on local recurrence and survival for chordomas and chondrosarcomas of the spine. 2. To determine the influence of radiation therapy in the management of chordomas and chondrosarcomas. SUMMARY OF BACKGROUND DATA Chordomas and chondrosarcomas of the spine are prone to local recurrence and death despite being low-grade malignant tumors. No study to date has enough numbers or adequate scientific rigor to determine the influence of resection or radiation therapy on outcome. METHODS A systematic review was performed to evaluate the 2 objectives. In addition an ambispective multicenter cohort analysis of chordomas and chondrosarcomas was performed. The GRADE system of analysis integrating the results of the systematic review, the multicenter cohort study and the expert opinion of the Spine Oncology Study Group (SOSG) was used to arrive at treatment recommendations. RESULTS A total of 63 articles were included in the systematic reviews. Evidence was low quality. En bloc resection appeared to improve both local recurrence and disease free survival in Chordoma and Chondrosarcoma. Radiation therapy had a positive impact on the management of Chordoma and Chondrosarcoma with predictably low side effects. The cohort analysis showed significantly decreased local recurrence for Chordoma (P < 0.0001) and Chondrosarcoma (P < 0.0001) with en bloc resection, and significantly decreased death for both Chordoma (P = 0.0001) and Chondrosarcoma (P = 0.0015) with en bloc resection. CONCLUSION When wide or marginal margins (en bloc) are achieved in surgical resection of chordomas and chondrosarcomas of the spine there is a decrease in local recurrence and mortality. Therefore, en bloc resection should be undertaken for the treatment of chordomas and chondrosarcomas of the spine. Strong Recommendation, Moderate Quality Evidence.Radiation therapy of at least 60 to 65 Gy equivalents is indicated as an adjuvant treatment for chordoma and chondrosarcoma of the spine when there has been incomplete resection or an intralesional margin. Weak Recommendation, Low Quality Evidence.
