✓ The authors report the case of a 53-year-old woman with monostotic fibrous dysplasia of the thoracic spine. The patient presented with a 1-month history of pain in the thoracic spinal region. En bloc resection of the lesion was successfully performed via a transthoracic approach, and a histopathological examination confirmed the diagnosis of fibrous dysplasia. At 24-month follow-up examination, pain and vertebral instability were absent. The findings in this case illustrate that, although very rare, monostotic fibrous dysplasia of the thoracic spine should be considered in the differential diagnosis of spinal tumors. Although a consensus for management of this disease has not been achieved, the authors recommend radical removal of all involved bone as well as internal fixation or bone graft—assisted fusion to achieve long-term stabilization.

Background: Primary spinal tumors are rare benign lesions that represent around 2–4% of all central nervous system neoplasms.[1,2] Intradural intramedullary tumors are predominately glial in origin and are most commonly astrocytomas or ependymomas. Intradural extramedullary tumors, on the other hand, are usually neurofibromas, schwannomas, or meningiomas.[2] Here, we report the case of an intradural intramedullary collision tumor of schwannoma-hemangioblastoma origin. Case Description: A 61-year-old female presented with a 2-year history of the right arm numbness, weakness, and tingling. She reported some lower extremity numbness but an otherwise normal neurological examination. She had a prior carpal tunnel release that did not alleviate her symptoms. Noncontrast MRI of the cervical spine demonstrated a holocord syrinx from C2 to C7 and spondylolisthesis from C4 to C5. MRI with contrast then displayed an enhancing nodule behind the vertebral body of C4. A standard posterior approach and subperiosteal dissection were performed. Lateral mass screws were placed at C3-C5, and the laminectomy was performed en bloc. Intraoperative ultrasound was used to locate the lesion, and intraoperative dorsal column mapping was used to identify the midline before performing a midline myelotomy. The arachnoid over the lesion was opened and an extracapsular dissection was performed. Hemostasis was obtained, and a watertight dural closure was performed. Conclusion: The patient tolerated the procedure well and achieved relief from cervical myelopathy symptoms. Pathology indicated positive biomarkers for S-100, SOX10, and NSE indicating a schwannoma hemangioblastoma collision tumor. This is unusual in its nature given two benign lesions with differing underlying cell types of origin.

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.

Bloc Spondylectomy

Object Spinal metastases are prevalent in the population of patients with cancer. Effective cancer therapy must incorporate treatment strategies for these lesions. Increasingly, surgery is being recognized as an effective treatment modality both for the patient's quality of life and potential oncological cure. En bloc spondylectomy is the surgical procedure of choice to obtain these goals. The purpose of this study was to examine critically the rationale, indications, and outcomes of en bloc spondylectomy for spinal metastases. Methods Outcomes in the authors' series of patients who underwent en bloc spondylectomy for spinal metastases are critically analyzed. The rationale and indications for this procedure are discussed. The Weinstein, Boriani, and Biagini surgical staging system for spinal tumors is described. A review of the literature is performed to examine further the rationale underlying this aggressive surgical approach to metastatic spinal disease. Conclusions En bloc spondylectomy is the treatment of choice for solitary and oligometastatic spinal metastases with biologically favorable histological findings. In appropriately selected patients, neurological outcome, pain control, and oncological control are significantly better after en bloc spondylectomy compared with radiation therapy. Oncological outcomes also exceed those of intralesional techniques. The Weinstein, Boriani, and Biagini surgical staging system provides a standard with which to plan surgical approaches and to compare surgical outcomes.

Background: En-bloc spondylectomy in the treatment of spinal tumors is a complex procedure with potential complications. This study aims at identifying predictors of postoperative complications, lesion recurrence and overall survival. Methods: A systematic review of the literature was conducted, and patient-level data extracted from the included studies. Multiple linear-regression models were calculated to predict the occurrence of postoperative complications, lesion recurrence and overall survival based on age, tumor etiology, surgical approach, mode of resection (en-bloc versus intralesional), tumor extension based on Weinstein-BorianiBiagini classification system and number of levels treated. Results: Data of 582 individual adult and pediatric patients were extracted from the literature; Patient characteristics are: 45% female, median age of 46 years (range 5-78); most common etiologies were: sarcoma (46%), metastases (31%) and chordoma (11%). The surgical technique was: anterior (2.5%), combined (45%) and posterior approach (52.4%); 68.5% underwent en-bloc spondylectomy; average levels resected were 1.6 (1-6); 65% of patients had neurologic deficits at presentation, average survival was 2.6 years; Direct procedure-related complications were observed in 17.7%, with the most prevalent being CSF leaks, wound infections and neural injury. For postoperative complications, recurrence and 5-year survival significant regression equations were found (F(7,90)=2.57, p=0.018) with an R2 of 0.1; (F(5,147)=2.35, p=0.044) with an R2 of 0.07 and (F(4,101)=7.2, p=0.01) with an R2 of 0.38. Odds ratio for predicted complications was 1.35 for en-bloc resection and 1.25 for more than one level treated. The odds ratio for tumor recurrence was 0.78 for en-bloc resection; odds ratio for 5-year survival were 0.79 for increased patient age, 0.65 for increasing tumor grade, 0.79 for tumor dissemination at diagnosis and 1.68 for en-bloc resection. Conclusion: En-bloc spondylectomy provides improved survival and lower recurrence rates but also higher operative complication rates when compared to intralesional resections. Interestingly the complication rate was not influenced by tumor stage (WBB scale) and tumor etiology.
