Abstract
Spinal cord involvement of Wilms' tumour is rare. A 14-year-old girl presented with an abdominal mass, paraplegia and loss of bladder and bowel control. Radiological investigations confirmed the presence of a large intraabdominal mass with infiltration into the spinal canal with impingement of nerve roots and the spinal cord. Histopathological evaluation demonstrated a nephroblastoma. It was decided to commence prompt neoadjuvant chemotherapy to render the tumour amenable to surgical resection. The patient unfortunately demised before receiving her first dose. Early diagnosis and timeous initiation of treatment is critical in limiting morbidity and mortality associated with malignant spinal cord compression.

Abstract
Metastatic spinal cord compression, diagnosed in 3–7% of cancer patients, is one of the most dreaded complications of metastatic cancer. It is an oncologic emergency, which must be diagnosed early and treated promptly to achieve the best results and avoid progressive pain, paralysis, sensory loss and sphincter incontinence. Patients who are ambulatory at the time of the diagnosis have a higher probability of obtaining good response to treatment and a longer survival. In clinical practice, back pain accompanies metastatic spinal cord compression in most cases, even in patients with no neurologic deficits. Magnetic resonance imaging is the best tool for diagnosing metastatic spinal cord compression and is able to identify spinal cord compression in 32–35% patients with back pain, bone metastases and normal neurologic examination. Moreover, magnetic resonance imaging gives the extension of the lesion, can diagnose other unsuspected clinical metastatic spinal cord compression sites, and is useful for the radiation oncologist in defining the target volume. Radiotherapy is the treatment of choice in most cases, whereas surgery is advised only in selected patients (ie, if stabilization is necessary, if radiotherapy has already been given in the same area, when vertebral body collapse causes bone impingement on the cord or nerve roots, when there are diagnostic doubts, or when computed tomography-guided percutaneous vertebral biopsy cannot be performed). Laminectomy should be abandoned in favor of more aggressive surgery (ie, posterior, anterior, and/or lateral approach, tumor mass resection, and stabilization of the spine). Generally, radiotherapy must be administered 7–10 days after surgery. The optimal radiation schedule has not been defined. However, as recently suggested by some clinical trials, even the hypofractionated radiotherapy regimens are effective and can be used without increasing radiation-induced myelopathy. Moderate doses of dexamethasone should be used in the early phases of therapy. After radiotherapy, spinal recurrence is generally found in sites different from the first compression area. A close post-treatment follow-up is suggested using clinical parameters (pain, motor and sphincter function), and magnetic resonance imaging should be performed only when a second metastatic spinal cord compression and/or myelopathy are clinically suspected.

Assessing the utility of the spinal instability neoplastic score (SINS) to predict fracture after conventional radiation therapy (RT) for spinal metastases. Pract Radiat Oncol 2018; 8:e285-e294. [PMID: 29703703 DOI: 10.1016/j.prro.2018.02.001] [Citation(s) in RCA: 27] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2017] [Revised: 02/01/2018] [Accepted: 02/07/2018] [Indexed: 11/20/2022]
Abstract
PURPOSE Assessing the stability of spinal metastases is critical for making treatment decisions. The spinal instability neoplastic score (SINS) was developed by the Spine Oncology Study Group to categorize tumor-related lesions; however, data describing its utility in predicting fractures in patients with spinal metastases are limited. The purpose of this study is to assess the validity of SINS in predicting new or worsening fracture after radiation therapy (RT) to spine metastases. METHODS AND MATERIALS This is a retrospective analysis of patients treated with conventional RT alone (median total dose, 30 Gy; range, 8-47 Gy; median number of fractions, 10; range, 1-25) for spinal metastasis at Dana-Farber/Brigham and Women's Cancer Center from 2006 to 2013. SINS was calculated for each lesion (range, 0-18). The primary endpoint was time from RT start to radiographically documented new or worsening fracture or last disease assessment. RESULTS A total of 203 patients and 250 lesions were included in analysis. The percentages of lesions with SINS of 0 to 6, 7 to 12, and 13 to 18 were 38.8%, 54.8%, and 6.4%, respectively. Of 250 lesions, 20.4% developed new or worsening fractures; 14.4% for SINS 0 to 6, 21.2% for SINS 7 to 12, and 50.0% for SINS 13 to 18. Multivariate analysis adjusted for sex, age, Eastern Cooperative Oncology Group, histology, and total dose indicated that, compared with stable lesions (SINS 0-6), potentially unstable lesions (SINS 7-12) demonstrated a greater likelihood of new or worsening fracture that was not statistically significant (hazard ratio, 1.66; 95% confidence interval, 0.85-3.22; P = .14), and unstable lesions (SINS 13-18) were significantly more likely to develop to new or worsening fracture (hazard ratio, HR,4.37, 95% confidence interval, 1.80-10.61; P = .001). CONCLUSIONS In this study of patients undergoing RT for spinal metastases, 20.4% developed new or worsening vertebral fractures. SINS is demonstrated to be a useful tool to assess fracture risk after RT.

Abstract
Introduction: Anterior approach provides excellent visualization and access to the anterior thoracic spine. It may be used alone, in combination with a posterior midline approach or in a staged or sequential fashion. Aims: To analyse our institutional experience in transthoracic approaches and to determine the safety and benefit of this approach in our patient series. Materials and Methods: A total of 16 patients were operated for varying lesions of body of dorsal vertebra by the transthoracic approach. The study was for a period of 5 years from January 2011 to December 2015. Patients age ranged from 25 to 61 years with an average of 36.4 yrs. There were 7 males and 9 females. In our series 9 patients had Kochs spine, 4 patients were traumatic fracture spine and 3 had neoplastic lesion. Majority of patients had multiple symptoms with backache being present in all patients. Results: There was one post operative mortality which was unrelated to surgery. One patient had post operative delayed kyphosis. Remaining patients improved in their symptoms following surgery. Conclusion: With careful coordination by thoracic surgeons, neurospinal surgeons and anaesthetists, the anterior spine approach for dorsal spine is safe and effective. Adequate preoperative evaluation should stratify the risk and institute measures to reduce it. Accurate surgical planning and careful surgical technique are the key to yield a good outcome and to reduce the risk of complications.

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

Abstract
OBJECTIVE The authors' objective was to identify the 100 most-cited research articles in the field of spinal oncology. METHODS The Thomson Reuters Web of Science service was queried for the years 1864-2015 without language restrictions. Articles were sorted in descending order of the number of times they were cited by other studies, and all titles and abstracts were screened to identify the research areas of the top 100 articles. Levels of evidence were assigned on the basis of the North American Spine Society criteria. RESULTS The authors identified the 100 most-cited articles in spinal oncology, which collectively had been cited 20,771 times at the time of this writing. The oldest article on this top 100 list had been published in 1931, and the most recent in 2008; the most prolific decade was the 1990s, with 34 articles on this list having been published during that period. There were 4 studies with Level I evidence, 3 with Level II evidence, 9 with Level III evidence, 70 with Level IV evidence, and 2 with Level V evidence; levels of evidence were not assigned to 12 studies because they were not on therapeutic, prognostic, or diagnostic topics. Thirty-one unique journals contributed to the 100 articles, with the Journal of Neurosurgery contributing most of the articles (n = 25). The specialties covered included neurosurgery, orthopedic surgery, neurology, radiation oncology, and pathology. Sixty-seven articles reported clinical outcomes. The most common country of article origin was the United States (n = 62), followed by Canada (n = 8) and France (n = 7). The most common topics were spinal metastases (n = 35), intramedullary tumors (n = 18), chordoma (n = 17), intradural tumors (n = 7), vertebroplasty/kyphoplasty (n = 7), primary bone tumors (n = 6), and others (n = 10). One researcher had authored 6 studies on the top 100 list, and 7 authors had 3 studies each on this list. CONCLUSIONS This study identified the 100 most-cited research articles in the area of spinal oncology. The studies highlighted the multidisciplinary and multimodal nature of spinal tumor management. Recognition of historical articles may guide future spinal oncology research.

Abstract
BACKGROUND Survival is a key factor physicians consider when selecting a treatment modality for the treatment of spinal metastases. Various assessment systems can predict length of survival and facilitate selection of the most appropriate treatment. Spinal palsy is a prognostic parameter in the Tokuhashi scoring system but not in the Tomita scoring system. A limitation of these scoring systems is that studies of them have included different tumor types. The aim of this study was to evaluate the usefulness of preoperative neurological status as a prognostic factor in non-small-cell lung cancer patients with spinal metastases who underwent surgical treatment. METHODS From November 2000 to March 2010, 50 patients with symptomatic metastatic spinal cord compression secondary to non-small-cell lung cancer underwent palliative surgery. Data collected included patient age and sex, tumor histology, date of surgery, death or last follow-up, preoperative and postoperative ambulatory status according to the Frankel grading system, body mass index (BMI), number of vertebra involved, number of other bone metastasis, visceral metastasis, and preoperative Karnofsky performance status. Log-rank test and multivariate Cox proportional hazard regressions were used to evaluate possible prognostic factors. RESULTS The mean patient age was 61.6 years (range, 20-87 years), and 34 were male and 16 were female. The median postoperative survival time was 7.5 months. The median survival was 2.5 months (95% confidence interval (CI): 1.22-16.3 months) in the Frankel A + B group and 8.0 months (95% CI: 5.52-9.89 months) in the Frankel C + D group (p = 0.87). Multivariate Cox proportional hazard regressions showed that preoperative performance status was significantly associated with survival. Preoperative palsy score had no statistically significant association with survival. CONCLUSIONS Preoperative palsy score had no statistically significant association with survival in non-small-cell lung cancer patients with spinal metastases who underwent spinal surgery in this study.

Abstract
BACKGROUND Circumferential decompression has been demonstrated to be the first-line therapy for patients with metastatic tumors in the thoracic spine requiring surgical intervention. However, there is significant debate regarding whether these tumors are best accessed anteriorly utilizing a thoracotomy or posteriorly. We used decision analysis to determine which approach yields greater health-related quality of life (QOL). METHODS We searched Medline, Embase, and the Cochrane Library for relevant articles published between 1990 and 2011 on anterior and posterior approaches to metastatic disease in the thoracic spine. QOL values for major treatment outcomes were determined using the existing literature. Separate models were created for ambulatory and nonambulatory patients. A Monte Carlo simulation and sensitivity analyses were used to determine which treatment strategy resulted in the highest QOL. RESULTS For ambulatory patients, an anterior approach resulted in a slightly higher QOL, and for nonambulatory patients, a posterior approach was favored, but these differences were not statistically significant. CONCLUSIONS Using a decision-analytic model, we found no significant difference in QOL resulting from anterior versus posterior approaches to metastatic lesions in the thoracic spine. Decisions should instead be based on surgeon comfort, tumor characteristics, anatomy of the lesion, patient-related factors, and goals of the operation.

Abstract
INTRODUCTION Management of metastatic spine disease is quite complex. Advances in research have allowed surgeons and physicians to better provide chemotherapeutic agents that have proven more efficacious. Additionally, the advancement of surgical techniques and radiosurgical implementation has altered drastically the treatment paradigm for metastatic spinal disease. Nevertheless, the physician-patient relationship, including extensive discussion with the neurosurgeon, medicine team, oncologists, radiation oncologists, and psychologists, are all critical in the evaluation process and in delivering the best possible care to our patients. The future remains bright for continued improvement in the surgical and nonsurgical management of our patients with metastatic spine disease. METHODS We include an evidence-based review of decision making strategies when attempting to determine most efficacious treatment options. Surgical treatments discussed include conventional debulking versus en bloc resection, conventional RT, and radiosurgical techniques, and minimally invasive approaches toward treating metastatic spinal disease. CONCLUSIONS Surgical oncology is a diverse field in medicine and has undergone a significant paradigm shift over the past few decades. This shift in both medical and surgical management of patients with primarily metastatic tumors has largely been due to the more complete understanding of tumor biology as well as due to advances in surgical approaches and instrumentation. Furthermore, radiation oncology has seen significant advances with stereotactic radiosurgery and intensity-modulated radiation therapy contributing to a decline in surgical treatment of metastatic spinal disease. We analyze the entire spectrum of treating patients with metastatic spinal disease, from methods of diagnosis to the variety of treatment options available in the published literature.

Abstract
STUDY DESIGN Retrospective review of medical records. OBJECTIVE To describe pre- and postoperative ambulatory status and lower limb motor power, and compare characteristics of patients with metastatic spinal cord compression (MSCC) who were ambulatory at 48 hours postoperatively with those of patients with MSCC who were nonambulatory. SUMMARY OF BACKGROUND DATA Preoperative motor power of the lower extremities is a predictor of postoperative ambulatory status in patients with MSCC. METHODS We retrospectively evaluated the medical records of 102 consecutive patients with MSCC who presented for decompressive surgery with lower extremity weakness between January 1997 and December 2010. A single surgeon classified the preoperative and 48-hour postoperative motor power of the lower extremities on a 6-point scale. Ambulation status was determined 48 hours after surgery and patients were classified as ambulatory (including normal ambulation, ambulation with aid, and ambulation without aid) or nonambulatory. Demographic and clinical characteristics were compared between patients who were ambulatory and those who were nonambulatory at 48 hours postoperatively. RESULTS Motor power was improved 1.05 ± 0.73 grades after operation. Two-thirds of patients who were preoperatively classified as nonambulatory were ambulatory at 48 hours postoperatively. The only significantly different affecting factor between the postoperative ambulatory group and the nonambulatory group was preoperative lower extremity power and preoperative capability of ambulation. In addition, grade III of lower extremity motor power was significant criteria for postoperative ambulation. CONCLUSION We recommend aggressive decompressive surgery in patients with MSCC if preoperative lower extremity motor power is at least grade III, although all groups of preoperative lower extremity motor power had 1 or more patients who returned to ambulation. LEVEL OF EVIDENCE 3.

Abstract
The present study discusses a patient with C1 vertebral metastasis from adenocarcinoma of the left lung. The patient was a 31-year-old female suffering from neck pain who was referred by her physician. Magnetic resonance imaging revealed osteolytic destruction of the C1 vertebra. Chest and computed tomographic scans revealed lung carcinoma changes involving the left lung. A biopsy confirmed adenocarcinoma of the left lung. Abnormal activity was present in the cervical spine (C1) region in a radionuclide bone scan. The patient was then referred to an oncologist. The spine was stabilized with a rigid collar and a course of radiation therapy and pain medication was initiated immediately. At the 9-month follow-up examination, there was no evidence of progression on the MRI scans and the main neck symptoms had disappeared. At present, the overall survival (OS) time is 11 months. Patients complaining of new onset back or neck pain should be assumed to have vertebral metastasis until proven otherwise. Trivial trauma should be taken seriously in these cases and investigated with appropriate clinical, laboratory and imaging examinations.

Abstract
The purpose of this study was to determine the feasibility of performing far-lateral lumbar discectomy by using the microendoscopic discectomy (MED) technique. The authors studied 11 consecutive patients with unilateral, single-level radiculopathy secondary to far-lateral disc herniation. There were eight men and three women, with an average age of 43 years. In all patients magnetic resonance imaging and/or computerized tomography scanning documented far-lateral disc herniations. Six patients experienced motor deficits, nine patients sensory abnormalities, and five depressed reflexes. All patients complained of radicular pain, which failed to improve with conservative care. After induction of epidural anesthesia, single-level, unilateral percutaneous discectomies were performed using the MED technique. Five discectomies were performed at L3-4 and six at L4-5. There were four contained and seven sequestered disc herniations. All surgeries were performed on an outpatient basis. Follow up ranged from for 12 to 27 months. Improvement was shown in all patients postoperatively. Using modified Macnab criteria to assess results of surgery, there were 10 excellent results and one good result. None of the patients experienced residual motor deficits, four had residual decreased sensation, and one still had some degree of nonradicular pain. There were no complications. Although various open techniques exist for the treatment of far-lateral disc herniation, MED is unique in that far-lateral pathological entities can be directly visualized and removed via a 15-mm paramedian incision. The percutaneous approach avoids larger, potentially denervating and destabilizing procedures. The need for general anesthesia can be avoided, and surgery is performed on an outpatient basis, thereby reducing hospital cost and length of stay.

Abstract
BACKGROUND Metastatic spinal tumors are common and major causes of pathological spinal fractures that result in severe pain, weakness, and progressive neurological deficits. This study aims to evaluate the efficacy of percutaneous vertebroplasty (PVP) in pain-relief in patients with spinal fractures due to metastatic spinal tumors. METHODS We evaluated 25 documented cases of metastatic spinal tumors with pathologic vertebral fractures who were suffering from severe pain and underwent vertebroplasty. Degree of pain was measured by visual analog scale (VAS). The symptoms were evaluated 24 hours and 2 months after vertebroplasty regarding the degree of pain relief.Complications such as leakage, embolism and infection were assessed. RESULTS MeanVAS score was 8.23 before therapy in the patients that was reduced to 2.12 and 1 in the patients 24 hours and 2 months after vertebroplasty, respectively. The most common complication was cement leakage (44%) and there was no embolism or infection. Data was analyzed by SPSS version 18 software through ANOVA test with Greenhouse-Geisser correction and P-value of 0.00 was obtained in the patients 24 hours and 1 month after surgery. CONCLUSION Considering significant decrease in the mean pain severity degree after the treatment, veretebroplasty seems to be significantly effective in pain relief in metastatic spinal tumors.

Abstract
Metastatic spine disease accounts for 10% to 30% of new cancer diagnoses annually. The most frequent presentation is axial spinal pain. No treatment has been proven to increase the life expectancy of patients with spinal metastasis. The goals of therapy are pain control and functional preservation. The most important prognostic indicator for spinal metastases is the initial functional score. Treatment is multidisciplinary, and virtually all treatment is palliative. Management is guided by three key issues; neurologic compromise, spinal instability, and individual patient factors. Site-directed radiation, with or without chemotherapy is the most commonly used treatment modality for those patients presenting with spinal pain, causative by tumours which are not impinging on neural elements. Operative intervention has, until recently been advocated for establishing a tissue diagnosis, mechanical stabilization and for reduction of tumor burden but not for a curative approach. It is treatment of choice patients with diseaseadvancement despite radiotherapy and in those with known radiotherapy-resistant tumors. Vertebral resection and anterior stabilization with methacrylate or hardware (e.g., cages) has been advocated.Surgical decompression and stabilization, however, along with radiotherapy, may provide the most promising treatment. It stabilizes the metastatic deposited areaand allows ambulation with pain relief. In general, patients who are nonambulatory at diagnosis do poorly, as do patients in whom more than one vertebra is involved. Surgical intervention is indicated in patients with radiation-resistant tumors, spinal instability, spinal compression with bone or disk fragments, progressive neurologic deterioration, previous radiation exposure, and uncertain diagnosis that requires tissue diagnosis. The main goal in the management of spinal metastatic deposits is always palliative rather than curative, with the primary aim being pain relief and improved mobility. This however, does not come without complications, regardless of the surgical intervention technique used. These complication range from the general surgical complications of bleeding, infection, damage to surrounding structures and post operative DT/PE to spinal specific complications of persistent neurologic deficit and paralysis.

Abstract
STUDY DESIGN Systematic literature review from 1970 to 2007. OBJECTIVE This study reports the results of a systematic review comparing surgical decompression ± radiation to radiation therapy alone among patients with metastatic spinal cord compression. SUMMARY OF BACKGROUND DATA Currently, the optimal treatment of metastatic spine lesions is not well defined and is inconsistent. Radiation and surgical excision are both accepted and effective. There appears to be a favorable trend for improved neurological outcome with surgical excision and stabilization as part of the management. METHODS A review of the English literature from 1970 to 2007 was performed in the Medline database using general MeSH terms. Relevant outcome studies for the treatment of metastatic spinal cord compression were selected through criteria defined a priori. The primary outcome was ambulatory capacity. A random effects model was built to compare results between treatment groups, based on calculated proportions from each study. RESULTS Of the 1595 articles screened, 33 studies (2495 patients) were selected based on our inclusion and exclusion criteria. Sixty-four percent of the patients who underwent surgical decompression, tumor excision, and stabilization had neurological improvement from nonambulatory to ambulatory status. Twenty-nine percent of the radiation therapy group regained the ability to ambulate after treatment (P < 0.001). Paraplegic patients had a 4-fold greater recovery rate to functional ambulation with surgical intervention than with radiation therapy alone (42% vs. 10%, P < 0.001). Pain relief was noted in 88% of the patients in the surgical studies and in 74% of the patients in studies of radiation therapy (P < 0.001). The overall surgical complication rate was 29%. CONCLUSION This systematic review suggests that surgical excision of tumor and instrumented stabilization may improve clinical outcomes compared with radiation therapy alone, with regard to neurological function and pain. However, most data in the current literature are from observational studies, where variations in patient population and treatments cannot be controlled. This compromised our ability to compare the results of both treatments directly.

Abstract
OBJECTIVE The goals of surgical intervention for metastatic spinal cord compression (MSCC) are prolonging survival and improving quality of life. Non-ambulatory paraplegic patients, either at presentation or after treatment, have a much shorter life expectancy than ambulatory patients. We therefore analyzed prognostic factors for survival and postoperative ambulation in patients surgically treated for MSCC. METHODS We assessed 103 patients with surgically treated MSCC who presented with lower extremity weakness between January 2001 and December 2008. Factors prognostic for overall survival (OS) and postoperative ambulation, including surgical method, age, sex, primary tumor site, metastatic spinal site, surgical levels, Tokuhashi score, and treatment with chemo- or radiation therapy, were analyzed retrospectively. RESULTS Median OS was significantly longer in the postoperatively ambulatory group [11.0 months; 95% confidence interval (CI), 9.29-12.71 months] than in the non-ambulatory group (5.0 months; 95% CI, 1.80-8.20 months) (p=0.035). When we compared median OS in patients with high (9-11) and low (0-8) Tokuhashi scores, they were significantly longer in the former (15.0 months; 95% CI, 9.29-20.71 months vs. 9.0 months; 95% CI, 7.48-10.52 months; p=0.003). Multivariate logistic regression analysis showed that preoperative ambulation with or without aid [odds ratio (OR) 5.35; 95% CI 1.57-18.17; p=0.007] and hip flexion power greater than grade III (OR 6.23; 95% CI, 1.29-7.35; p=0.038) were prognostic of postoperative ambulation. CONCLUSION We found that postoperative ambulation and preoperative high Tokuhashi score were significantly associated with longer patient survival. In addition, preoperative hip flexion power greater than grade III was critical for postoperative ambulation.

Abstract
Anterior decompression in spinal metastases of the corporal type with impending (n = 5) or present (n = 36) neurological complications was performed in 41 patients. For reconstruction, a titanium cylinder was inserted after spondylectomy and augmented with an anterior plate. The titanium implant can easily be adjusted to the length needed without necessitating expensive additional equipment. Outside the patient the implant is filled with polymethylmetacrylate, facilitating plate transfixation for rotational locking. There was a 30-day mortality of 9.7%. Pain relief was apparent in 38 of 41 patients (92.7%), and motor improvement was manifest in 31 of 35 cases (88.6%). Six patients did not present with any neurological symptoms pre- or postoperatively. Neurological deterioration was registered in only 1 case (2.4%). Surgical efficacy was maintained until the death of the patients. Though tumor recurrence at a different spinal level led to consecutive surgery in 5 patients, no implant dislocation occurred during the observation period (maximum 44 months), characterizing the procedure as a mechanically reliable and safe technique.

Abstract
STUDY DESIGN A review of the past and current status of the evolving field of spine oncology. OBJECTIVE To provide a framework of reference for developments in the field, particularly the rapidly evolving field of molecular biology, as well as contemporary practice in the management of spine tumors. METHODS Literature review of the surgical treatment of spine tumors in the past and present, the emerging radiologic and biologic technologies, as well as the field of targeted therapy in cancer and the economic implications of technological advances. RESULTS A vast contemporary literature is currently available that provides a clear rational basis for treatment. Most treatment recommendations are currently based on retrospective data and small Phase II prospective studies. Treatment paradigms continue to evolve without their relative merits being evaluated by randomized controlled trials. The current lack of randomized trials in spine oncology reflect both the rarity of spine tumors and strongly held biases based on retrospective studies and institutional bias. CONCLUSION Spine oncology is a rapidly evolving field with contributions in surgery, radiation therapy, and targeted chemotherapy resulting in overall improvement in quality of life and survival in patients with spine tumors. However, the economic consequences of these improvements are substantial and need to be kept in proper perspective.

Abstract
INTRODUCCIÓN: debido a los resultados clínicos no satisfactorios con instrumentaciones posteriores en los casos de tumor vertebral y a las carencias económicas de nuestros pacientes para adquirir los sistemas disponibles en el mercado, fue diseñada una prótesis de cuerpo vertebral para estabilizar la columna después de una corpectomía. OBJETIVO: describir las características estructurales y funcionales de la prótesis JR, las pruebas biomecánicas en cadáver y la técnica quirúrgica en el paciente. MÉTODOS: primeramente fue realizado un estudio anatómico detallado de los cuerpos vertebrales. Se obtuvo el diseño de un dispositivo modular, anatómico y expandible. Sus componentes una vez ensamblados hacen un implante con función dual de jaula y placa lateral expandibles. Posteriormente se efectuó un ensayo de propiedades biomecánicas en cadáver y se implantó un dispositivo en un paciente con metástasis en cuerpo vertebral. RESULTADOS: las radiografías que le fueron tomadas al cadáver, posterior a la colocación del implante, no mostraron pérdida de la fijación. Al levantar el cadáver se generaron momentos de flexión en sentido lateral con brazos de palanca de 80 cm de largo, por lo que la prótesis fue demandada en su punto más vulnerable con una fuerza de aproximadamente 588 N. Con la rotación, flexión y extensión forzadas, la estabilidad se conservó y no se visualizó movimiento del implante. Se colocó el dispositivo en una mujer de 50 años con cáncer metastásico de tiroides que afectaba L3. El dolor mejoró en el postoperatorio inmediato, así como su función motora que le permitió caminar con una columna estable e indolora por siete años. No se observó fracaso del implante. CONCLUSIÓN: la función dual de jaula y placa integrada en la prótesis de cuerpo vertebral establece una ventaja mecánica comparada con la función de la jaula y de la placa separadamente, ya que el diseño de la prótesis permite aplicar fuerza axial y fijación lateral al mismo tiempo, a través de solo un implante. Los resultados de la colocación del implante en paciente son satisfactorios.

Abstract
OBJECTIVE To find vertebral metastases with high risk of symptomatic malignant spinal cord compression (MSCC), features of vertebral metastases caused motor deficits of the lower extremities were examined. METHODS From 2004 through 2006, 78 patients with metastases of the thoracic and/or the cervical spine were treated with radiation therapy (RT). Of these, 86 irradiated lesions in 73 patients were evaluable by magnetic resonance imaging and/or computed tomography at the initiation of RT and were reviewed retrospectively in this study. Twenty-eight patients (38%) had motor deficits at the initiation of RT. Assessed factors were age, sex, primary disease (lung, breast, digestive system and other cancer), lamina involvement, main level of tumor location and vertebral-body involvement. RESULTS Incidence of motor deficits at the initiation of RT was 55% for lesions with lamina involvement and 5% for lesions without lamina involvement (P < 0.0001). Incidence of motor deficits was 15% for lesions located mainly in the cervical spine and/or the upper thoracic spine (Th1-4), 54% for lesions located mainly in the middle thoracic spine (MTS) (Th5-8) and 30% for lesions located mainly in the lower thoracic spine (Th9-12) (P = 0.0095). Age, sex, primary disease and vertebral-body involvement were not statistically significant factors for incidence of motor deficits due to MSCC (P > 0.9999, P = 0.7798, P = 0.1702 and P = 0.366, respectively). CONCLUSIONS Vertebral metastases with lamina involvement tended to cause symptomatic MSCC. Latent development of MSCC occurred more frequently in the MTS compared with other levels of the thoracic and the cervical spine.

Significant improvements in neurological function and pain relief are the benefits of aggressive surgical management of spinal metastatic disease. However, there is limited literature regarding the management of tumors with specific histological features. In this study, a series of patients undergoing spinal surgery for metastatic prostate cancer were reviewed to identify predictors of survival and functional outcome.

The authors retrospectively reviewed the records of all patients who were treated with surgery for prostate cancer metastases to the spine between 1993 and 2005 at a single institution. Particular attention was given to initial presentation, operative management, clinical and neurological outcomes, and factors associated with complications and overall survival.
Results
Forty-four patients underwent a total of 47 procedures. The median age at spinal metastasis was 66 years (range 50–84 years). Twenty-four patients had received previous external-beam radiation to the site of spinal involvement, with a median dose of 70 Gy (range 30–74 Gy). Frankel scores on discharge were significantly improved when compared with preoperative scores (p = 0.001). Preoperatively, 32 patients (73%) were walking and 33 (75%) were continent. On discharge, 36 (86%) of 42 patients were walking, and 37 (88%) of 42 were continent. Preoperatively, 40 patients (91%) were taking narcotics, with a median morphine equivalent dose of 21.5 mg/day, and 28 patients (64%) were taking steroids, with a median dose of 16 mg/day. At discharge, the median postoperative morphine equivalent dose was 12 mg/day, and the median steroid dose was 0 mg/day (p < 0.001). Complications occurred in 15 (32%) of 47 procedures, with 9 (19%) considered major, and there were 4 deaths within 30 days of surgery. The median overall survival was 5.4 months. Gleason score (p = 0.002), total number of metastases (p = 0.001), and the degree of spinal canal compression (p = 0.001) were independent predictors of survival. Age ≥ 65 years at the time of surgery was an independent predictor of a postoperative complication (p = 0.005).
Conclusions
In selected patients with prostate cancer metastases to the spine, aggressive surgical decompression and spinal reconstruction is a useful treatment option. The results show that on average, neurological outcome is improved and use of analgesics is reduced. Gleason score, metastatic burden, and degree of spinal canal compression may be associated with survival following surgery, and thus should be considered carefully prior to opting for surgical management.

Abstract
OBJECTIVE Benign and malignant tumors of the spine significantly impair the function and quality of life of many patients. Standard treatment options, including conventional radiotherapy and surgery, are often limited by anatomic constraints and previous treatment. Image-guided stereotactic radiosurgery using the CyberKnife system (Accuray, Inc., Sunnyvale, CA) is a novel approach in the multidisciplinary management of spinal tumors. The aim of this study was to evaluate the effects of CyberKnife stereotactic radiosurgery on pain and quality-of-life outcomes of patients with spinal tumors. METHODS We conducted a prospective study of 200 patients with benign or malignant spinal tumors treated at Georgetown University Hospital between March 2002 and September 2006. Patients were treated by means of multisession stereotactic radiosurgery using the CyberKnife as initial treatment, postoperative treatment, or retreatment. Pain scores were assessed by the Visual Analog Scale, quality of life was assessed by the SF-12 survey, and neurological examinations were conducted after treatment. RESULTS Mean pain scores decreased significantly from 40.1 to 28.6 after treatment (P < 0.001) and continued to decrease over the entire 4-year follow-up period (P < 0.05). SF-12 Physical Component scores demonstrated no significant change throughout the follow-up period. Mental Component scores were significantly higher after treatment (P < 0.01), representing a quality-of-life improvement. Early side effects of radiosurgery were mild and self-limited, and no late radiation toxicity was observed. CONCLUSION CyberKnife stereotactic radiosurgery is a safe and effective modality in the treatment of patients with spinal tumors. CyberKnife offers durable pain relief and maintenance of quality of life with a very favorable side effect profile.

Abstract
STUDY DESIGN We conducted a retrospective study to examination the influence of preoperative duration of symptoms on the clinical outcome of patients that underwent surgical decompression because of neurologic deficit in metastatic disease of the spine. OBJECTIVES.: Our aim was to investigate possible correlations between the duration of neurologic deficit before surgery and postoperative outcome with respect to neural recovery in patients with spinal metastases, and second, based on those results, propose criteria for the timing of surgery in these patients. SUMMARY OF BACKGROUND DATA It has not yet been determined whether the duration of preoperative symptoms has an influence on the postoperative outcome of patients with vertebral metastases. A standardized treatment or protocol defining a strategy of surgical treatment has yet to be designed. METHODS This study includes 194 patients. The duration of symptoms before surgical treatment and the neurologic status before and after operation were determined and classified according to the Frankel score. RESULTS Of 401 patients, who underwent surgery due to metastases to the spine, 194 suffered from neurologic deficit. Analyzing the postoperative neurostatus in these patients revealed an improvement in 78 patients (40%), impairment in 13 patients (7%), and in 103 patients it did not change. The relation of duration of neurologic symptoms before surgery, and the outcome after an operation was highly significant (P < 0.001). In patients with less than 3 days of neurologic deficit, the probability of improvement in neurostatus was highly significantly higher (P < 0.001) than in patients with neurologic deficit existing for more than 15 days. CONCLUSION Patients with neurologic deficit because of spinal bone metastases benefit from early operative intervention. Urgent surgery is indicated in patients with less than 3 days of neurologic deficit.

Abstract
STUDY DESIGN Retrospective clinical study. OBJECTIVE The aim of this study was to examine whether the Tokuhashi score correlates with the neurologic outcome in early surgical treatment in metastatic spinal cord compression (MSCC). A retrospective analysis of 35 consecutive incomplete tetraplegic and paraplegic patients with vertebral metastases (VM) and spinal cord compression (SCC) was performed. SUMMARY OF BACKGROUND DATA MSCC is a challenging problem in VM and constitutes an oncologic emergency. The Tokuhashi score has been modified recently and seems to constitute the best method of prediction for real survival in patients with VM. Until now the influence of the neurologic status as a prognostic factor has been discussed controversially. METHODS Data of 35 patients with VM and incomplete tetraplegia or paraplegia, who underwent surgical treatment, were reviewed retrospectively from 2005 to 2006 at our hospital. All patients were classified among the American Spinal Injury Association (ASIA) Impairment Scale (AIS) before and after surgery and at the follow-up. Data were analyzed with SPSS 15.0 and correlation coefficients (Spearman rho) were computed. RESULTS Analysis showed that 19 patients (54.3%) with an average Tokuhashi score of 9 showed an improvement in the AIS, whereas 12 (34.3%) patients with an average score of 8 had no change and 4 (11.4%) patients with a score of 7 had deterioration. AIS changes showed a positive correlation with Tokuhashi score (r = 0.33; P = 0.048). CONCLUSION Our clinical observation suggests that patients with spinal metastases and a high Tokuhashi score benefit from surgical treatment with moderate improvement in sensomotoric function even in a heterogenic collective.

Abstract
STUDY DESIGN AND OBJECTIVE We present a series of 8 patients with thoracic metastatic disease causing acute neurologic decline. We present minimally invasive posterolateral vertebrectomy and decompression as an effective approach in patients with significant comorbidities and as palliative care. BACKGROUND Metastatic disease to the spine is common and frequently occurs in the thoracic vertebrae. Posterior laminectomy alone has generally been found to be ineffective in the management of spinal metastatic disease with neurologic compromise as most compression occurs ventrally. Patients with significant comorbidities are often unable to tolerate extensive surgery involving a thoracotomy. Limited life expectancy and quality of life issues also often argue against extensive surgery. METHODS Eight patients (mean age 74 y) with thoracic metastatic disease and acute neurologic compromise underwent a minimally invasive posterolateral vertebrectomy and partial tumor resection. Patients were considered unsuitable for an open anterior approach owing to age, comorbidities, and limited life expectancies. In the operating room, patients were positioned prone. A paramedian incision measuring 3 cm allowed the introduction of sequential dilators and the placement of a 22-mm diameter tubular retractor. Dorsal decompression was accomplished and partial vertebrectomy was performed for ventral decompression. Radiation was used postoperatively in all patients. RESULTS There were no complications due to the procedure. Improvement of at least 1 grade on the Nurick scale was noted in 5 of 8 (62.5%) patients. Two patients were able to ambulate independently immediately after surgery despite having significant paraparesis preoperatively. Pain improved in 5 of 8 (62.5%) patients postoperatively according to the numerical pain score. Average inpatient length of stay was 4 days after the procedure. Mean blood loss was 227 mL and mean length of the procedure was 2.2 hours. CONCLUSIONS Minimally invasive transpedicular vertebrectomy is an effective palliative treatment option for thoracic metastatic disease in patients not eligible for more extensive anterior transthoracic surgery and stabilization.

Abstract
OBJECT Opinions vary widely as to the role of surgery (from none to wide margin excision) in the management of spinal metastases. In this study the authors set out to ascertain if surgery improves the quality of remaining life in patients with spinal metastatic and tumor-related systemic disease. METHODS The authors included 223 patients in this study who were referred by oncologists and physicians over a 2-year period. All underwent surgery. Surgery was classified according to extent of excision ranging from en bloc excision or debulking to palliative surgery. All patients had a histologically confirmed diagnosis of epithelial spinal metastasis, and an oncology specialist undertook appropriately indicated adjuvant therapy in almost half of the patients. RESULTS The mean patient age was 61 years. Excisional en bloc or debulking surgery was performed in 74%; the rest had (minimal) palliative decompression. All patients considered for surgery were included in the study. Patients presented with pain in 92% of cases, paraparesis in 24%, and abnormal urinary sphincter function in 22% (5% were incontinent). Breast, renal, lung, and prostate accounted for 65% of the cancers, and in 60% of patients there were widespread spinal metastases (Tomita Type 6 or 7). The incidence of perioperative death (within 30 days of surgery) was 5.8%. Postoperatively 71% of the entire group had improved pain control, 53% regained or maintained their independent mobility, and 39% regained urinary sphincter function. The median survival for the cohort was 352 days (11.7 months); those who underwent excision survived significantly longer than those in the palliative group (p = 0.003). As with survival results, functional improvement outcome was better in those who underwent excision. CONCLUSIONS Surgical treatment was effective in improving quality of life by providing better pain control, enabling patients to regain or maintain mobility, and offering improved sphincter control. Although not a treatment of the systemic cancer, surgery is feasible, has acceptably low mortality and morbidity rates, and for many will improve the quality of their remaining life.

Abstract
INTRODUCTION This study evaluated the intra- and post-surgical complications on tumor affected spines. Complications were analyzed according to selected patient groups so that risk factors could be determined. MATERIAL AND METHODS Between January 1999 and December 2004, 401 patients underwent surgery because of spinal metastases in the Department of Traumatology, General Hospital St. Georg in Hamburg. Data were obtained from the hospital's documentary system. The results of this study were compared to other published studies. RESULTS The average age of patients was 63 years (24-88) and there were 172 (42.9%) females and 229 (57.1%) males. A total of 118 (29.4%) patients suffered from 235 complications and 22 (5.5%) died. DISCUSSION Patient's age >70 years, patients with a preoperative neurological deficit, and patients with heavily bleeding metastases are at high risk for complications. The dorsoventral/dorsolateral approach had the highest complication rate.

Abstract
Aggressive surgical management of spinal metastatic disease can provide improvement of neurological function and significant pain relief. However, there is limited literature analyzing such management as is pertains to individual histopathology of the primary tumor, which may be linked to overall prognosis for the patient. In this study, clinical outcomes were reviewed for patients undergoing spinal surgery for metastatic breast cancer. Respective review was done to identify all patients with breast cancer over an eight-year period at a major cancer center and then to select those with symptomatic spinal metastatic disease who underwent spinal surgery. Pre- and postoperative pain levels (visual analog scale [VAS]), analgesic medication usage, and modified Frankel grade scores were compared on all patients who underwent surgery. Univariate and multivariate analyses were used to assess risks for complications. A total of 16,977 patients were diagnosed with breast cancer, and 479 patients (2.8%) were diagnosed with spinal metastases from breast cancer. Of these patients, 87 patients (18%) underwent 125 spinal surgeries. Of the 76 patients (87%) who were ambulatory preoperatively, the majority (98%) were still ambulatory. Of the 11 patients (13%) who were nonambulatory preoperatively, four patients were alive at 3 months postoperatively, three of which (75%) regained ambulation. The preoperative median VAS of six was significantly reduced to a median score of two at the time of discharge and at 3, 6, and 12 months postoperatively (P < 0.001 for all time points). A total of 39% of patients experienced complications; 87% were early (within 30 days of surgery), and 13% were late. Early major surgical complications were significantly greater when five or more levels were instrumented. In patients with spinal metastases specifically from breast cancer, aggressive surgical management provides significant pain relief and preservation or improvement of neurological function with an acceptably low rate of complications.

Abstract
The spine is the most frequent site of skeletal metastases. Among all spinal malignancies metastatic disease is most frequent and indicative of disseminating tumor disease. Depending on primary tumor entity, estimated survival time, general health status of the patient, presence of spinal instability and neurological deficits an oncological useful and patient-specific therapeutic intervention should be performed. New anterior approaches, resections and reconstruction techniques are making surgery a preferred method over radiation therapy. For differential indication of the multiple surgical treatment modalities prognostic scores are available to assist individual decision making. Indications for surgery include survival prognosis of minimum 3 months, intractable pain, progress of myelon compression and/or neurological deficits under radiochemotherapy, spinal instability and necessity for histological diagnosis. Resulting quality of life depends on efficient decompression of the spinal cord and restoration of spinal stability. To achieve these ultimate goals there are different anterior and posterior approaches, instrumentations and vertebral body replacement implants available. Preoperative embolization should be performed in hypervascular tumors, e.g., renal cell cancer. Vertebro-/Kyphoplasty as a percutaneous intervention should be considered for painful multisegmental disease and symptomatic osteolysis without epidural tumor compression to reach analgesia and stability. A multidisciplinary approach in patient selection, decision making and management is an essential precondition for complication avoidance and acceptable quality of life.

Abstract
Primary and metastatic spinal mesenchymal tumors are uncommon lesions. Surgical management of these tumors remains a challenge. En bloc wide resection provides the best chance for local tumor control and long-term survival. However, limitations to this technique include technical considerations (including neurovascular anatomy), patient selection, and tumor histology. Intralesional resection provides good neurologic outcomes, but local recurrence rates are high. Postoperative adjuvant chemotherapy with or without radiation may help to delay recurrence and improve outcomes. We present three cases of our surgical experience with spinal mesenchymal tumors for illustrative purposes.

Abstract
It has been estimated that genitourinary malignancies will account for 25% of new cancer diagnoses in the United States in 2005 (Jemal et al. 2005). While the incidence of many of these malignancies has increased over the past two decades, the mortality rates appear to be decreasing. Early cancer detection combined with improvements in surgical and nonsurgical oncologic therapy account for these trends. Although not common, newly diagnosed cancer patients occasionally present in an emergent, life-threatening manner that warrants immediate medical or surgical intervention. As the prevalence of genitourinary malignancies continues to expand, additional patients can be expected to develop disease or treatment-related complications. This chapter will serve to review the diagnosis and management of oncologic emergencies as they pertain to the urologist.

Abstract
The role of surgery for metastatic spine disease is palliative with the goals of achieving excellent neurologic and functional status, spinal stability, pain relief, and local tumor control. Although patients with metastatic spine tumors often have numerous medical and oncologic issues, careful perioperative planning and surgical techniques can help limit complications and help improve patient outcomes significantly.

Abstract
BACKGROUND Spinal epidural metastases are the most common spinal tumor, occurring in 10% of cancer patients. Malignant thymoma is a mediastinal tumor, with extrathoracic metastases occurring in 15% of patients to liver, kidney, and bone. Spinal metastasis is exceptionally rare. We present a case of thymoma with extradural metastasis and discuss the relevant literature. CASE REPORT We describe a 45-year old man presenting with back pain and hypoesthesia twelve years after a diagnosis of thymoma. A review of the literature reveals few cases of thymoma metastatic to the extradural spine. We describe a novel surgical approach allowing ventral spinal cord decompression through a posterior incision. CONCLUSION Spinal epidural metastases should be suspected in all cancer patients with back pain. Early detection of epidural metastases may enable improved pain control and preservation of spinal stability, ambulation and sphincter control.

Abstract
Palliative radiation therapy is considered when the incurable cancer patient has symptoms specifically related to a malignancy that may be relieved by localized treatment of the primary tumor or metastatic lesions. Developing a treatment plan with radiation in the palliative setting may be more difficult than the curative setting, where there are clear guidelines for many situations. Radiation therapy has been used successfully in the management of a variety of pain syndromes. Radiation also has proven effective in the management of other tumor-related symptoms, including bleeding, neurologic compromise, dysphagia, and airway obstruction. Palliative radiation can be delivered using a variety of techniques: external beam radiation therapy, intraluminal brachytherapy (radioactive seed delivery), and systemic radionucleotides.
