Kim TK, Cho W, Youn SM, Chang UK. The Effect of Perioperative Radiation Therapy on Spinal Bone Fusion Following Spine Tumor Surgery. J Korean Neurosurg Soc 2016; 59:597-603. [PMID: 27847573 PMCID: PMC5106359 DOI: 10.3340/jkns.2016.59.6.597] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2016] [Revised: 08/04/2016] [Accepted: 08/31/2016] [Indexed: 12/03/2022] Open
Abstract
Introduction Perioperative irradiation is often combined with spine tumor surgery. Radiation is known to be detrimental to healing process of bone fusion. We tried to investigate bone fusion rate in spine tumor surgery cases with perioperative radiation therapy (RT) and to analyze significant factors affecting successful bone fusion. Methods Study cohort was 33 patients who underwent spinal tumor resection and bone graft surgery combined with perioperative RT. Their medical records and radiological data were analyzed retrospectively. The analyzed factors were surgical approach, location of bone graft (anterior vs. posterior), kind of graft (autologous graft vs. allograft), timing of RT (preoperative vs. postoperative), interval of RT from operation in cases of postoperative RT (within 1 month vs. after 1 month) radiation dose (above 38 Gy vs. below 38 Gy) and type of radiation therapy (conventional RT vs. stereotactic radiosurgery). The bone fusion was determined on computed tomography images. Result Bone fusion was identified in 19 cases (57%). The only significant factors to affect bony fusion was the kind of graft (75% in autograft vs. 41 in allograft, p=0.049). Other factors proved to be insignificant relating to postoperative bone fusion. Regarding time interval of RT and operation in cases of postoperative RT, the time interval was not significant (p=0.101). Conclusion Spinal fusion surgery which was combined with perioperative RT showed relatively low bone fusion rate (57%). For successful bone fusion, the selection of bone graft was the most important.

Impact of spinal cord compression from intradural and epidural spinal tumors on perioperative symptoms-implications for surgical decision making. Neurosurg Rev 2016; 40:377-387. [PMID: 27714480 DOI: 10.1007/s10143-016-0790-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2016] [Revised: 08/29/2016] [Accepted: 09/26/2016] [Indexed: 11/25/2022]
Abstract
Spinal cord or cauda equina compression (SCC) is an increasing challenge in clinical oncology due to a higher prevalence of long-term cancer survivors. Our aim was to determine the clinical relevance of SCC regarding patient outcome depending on different tumor entities and their anatomical localization (extradural/intradural/intramedullary). We retrospectively analyzed 230 patients surgically treated for SCC. Preoperative status for pain and neurological impairment were correlated to the degree of compression, tumor location, and early as well as short-term follow-up outcome parameters. Interestingly, we did not observe any differences between intradural-extramedullary compared to extradural tumors. Unilaterally localized tumors were likely to present with pain (72.9 %, p < 0.01), whereas concentric growth was associated with motor deficits (41.0 %, p < 0.01, as primary symptom, 49.3 % on admission, p < 0.05). In concentric tumors, the pain pattern was diffuse (40.5 % vs. 17.5 in unilateral disease, p < 0.01), whereas unilateral tumors resulted in localized pain (61.4 % local axial or radicular, p < 0.01). Diffuse pain, patients without a sensory or motor deficit, progressive disease, cervical localization, and a higher degree of stenosis were identified as beneficial for an early improvement in pain (p < 0.05). Notably, 29 % of patients with unchanged pain and 30.8 % with unchanged neurologic function at day 7 postoperative improved during follow-up (p < 0.001). Our data demonstrate that the preoperative tumor anatomy in patients with SCC was closely related to their presenting symptoms and early clinical outcome. The detailed analysis elucidates the biology of SCC and might thereby aid in determining which patients will benefit from surgery.

Abstract
OBJECTIVES The study aimed to retrospectively evaluate the accuracy and value of magnetic resonance imaging (MRI) in predicting pedicle involvement for patients with spine metastases. METHODS Forty-five patients with a vertebral metastasis encroaching at least one pedicle were studied using MRI before surgery and regularly after surgery. Patients were categorized on the basis of their numbers of pedicle involvement (Group 1: one pedicle was involved, n = 23; Group 2: two pedicles were involved, n = 22). The diagnostic accuracy was calculated, and comparisons of intraoperative blood loss and recurrence rate between the two groups were performed. RESULTS The overall performance of MRI in predicting the pedicle involvement was as follows: accuracy, 94.4%; sensitivity, 95.5%; and specificity, 91.3%. Less intraoperative blood loss was observed for Group 1 compared with Group 2 (1,661 ± 672 ml and 2,173 ± 790 ml, respectively, P = 0.024). Tumor relapse occurred in 8.7% (2/23) of Group 1 and in 22.7% (5/22) of Group 2 with median recurrence free survival time 14 and 9 months, respectively. CONCLUSIONS MRI is a reliable approach to assess pedicle involvement. It has potential for use in the evaluation of the clinical characteristics of patients with spine metastases.

Abstract
ABSTRACT Objective: To analyze retrospectively the surgical outcomes of a group of patients with bone metastases and multiple myeloma in the spine, which underwent neurological decompression and arthrodesis using pedicle screws, by isolated posterior approach, to check whether the operated patients present clinical improvement regarding the pain and neurological deficit compared to the preoperative period. Methods: This is a retrospective, cross-sectional study of case series, that analyzed data from medical records of patients with bone metastases in the spine who underwent surgical treatment between January 2007 and February 2011. Results: Of the 42 patients in the sample, according to the Kolmogorov-Smirnov test (p=0.000) there was improvement in pain with respect to the preoperative, with 33 patients (78.6%) reporting improvement and only 9 (21.4%) maintaining the initial pain complaints. Of the 25 patients available for evaluation of neurological improvement (≠ Frankel E) 9 patients (36%) had some kind of improvement postoperatively, and no operated patient presented neurological worsening, indicating statistical significance according to the Kolmogorov-Smirnov test (p = 0.000). It was also observed statistical correlation (p=0.042) between Frankel functional score postoperatively and pain relief, using the chi-square test. Conclusions: Surgical treatment for patients with spinal metastasis through arthrodesis with pedicle instrumentation and decompression may have significant clinical benefits, especially as regards the improvement in pain symptoms and improved neurological function.

Abstract
OBJECTIVE
Despite the growing neurosurgical literature, a subset of pioneering studies have significantly impacted the field of metastatic spine disease. The purpose of this study was to identify and analyze the 100 most frequently cited articles in the field.
METHODS
A keyword search using the Thomson Reuters Web of Science was conducted to identify articles relevant to the field of metastatic spine disease. The results were filtered based on title and abstract analysis to identify the 100 most cited articles. Statistical analysis was used to characterize journal frequency, past and current citations, citation distribution over time, and author frequency.
RESULTS
The total number of citations for the final 100 articles ranged from 74 to 1169. Articles selected for the final list were published between 1940 and 2009. The years in which the greatest numbers of top-100 studies were published were 1990 and 2005, and the greatest number of citations occurred in 2012. The majority of articles were published in the journals Spine (15), Cancer (11), and the Journal of Neurosurgery (9). Forty-four individuals were listed as authors on 2 articles, 9 were listed as authors on 3 articles, and 2 were listed as authors on 4 articles in the top 100 list. The most cited article was the work by Batson (1169 citations) that was published in 1940 and described the role of the vertebral veins in the spread of metastases. The second most cited article was Patchell's 2005 study (594 citations) discussing decompressive resection of spinal cord metastases. The third most cited article was the 1978 study by Gilbert that evaluated treatment of epidural spinal cord compression due to metastatic tumor (560 citations).
CONCLUSIONS
The field of metastatic spine disease has witnessed numerous milestones and so it is increasingly important to recognize studies that have influenced the field. In this bibliographic study the authors identified and analyzed the most influential articles in the field of metastatic spine disease.

Abstract
Surgical interventions for spinal metastasis are commonly performed for mechanical stabilization, pain relief, preservation of neurological function, and local tumor reduction. Although multiple surgical approaches can be used for the treatment of metastatic spinal lesions, posterior approaches are commonly performed. In this study, the role of posterior surgical procedures in the treatment of spinal metastases was reviewed, including posterior laminectomy with and without instrumentation for stabilization, transpedicular corpectomy, and costotransversectomy. A review of the literature from 1980 to 2015 was performed using Medline, as was a review of the bibliographies of articles meeting preset inclusion criteria, to identify studies on the role of these posterior approaches among adults with spinal metastasis. Thirty-four articles were ultimately analyzed, including 1 randomized controlled trial, 6 prospective cohort studies, and 27 retrospective case reports and/or series. Some of the reviewed articles had Level II evidence indicating that laminectomy with stabilization can be recommended for improvement in neurological outcome and reduction of pain in selected patients. However, the use of laminectomy alone should be carefully considered. Additionally, transpedicular corpectomy and costotransversectomy can be recommended with the expectation of improving neurological outcomes and reducing pain in properly selected patients with spinal metastases. With improvements in the treatment paradigms for patients with spinal metastasis, as well as survival, surgical therapy will continue to play an important role in the management of spinal metastasis. While this review presents a window into determining the utility of posterior approaches, future prospective studies will provide essential data to better define the roles of the various options now available to surgeons in treating spinal metastases.

Abstract
Lung cancer is the second most prevalent cancer. Spinal metastases are found in 30-90% of patients with death attributed to cancer. Due to bony destruction caused by metastases, surgical intervention is often required to restore spinal alignment and stability. While some research suggests that BMP-2 may possess tumorigenic effects, other studies show possible inhibition of cancer growth. Thirty-six athymic rats underwent intraosseous injection of lung adenocarcinoma cells into the L5 vertebral body. Cells were pre-treated with vehicle control (Group A) or rhBMP-2 (Group B) prior to implantation. At 4 weeks post-implantation, in vivo bioluminescent imaging (BLI) was performed to confirm presence of tumor and quantify signal. Plain radiographs and microComputed Tomography (microCT) were employed to establish and quantitate osteolysis. Histological analysis characterized pathologic changes in the vertebral body. At 4 weeks post-implantation, BLI showed focal signal in the L5 vertebral body in 93% of Group A animals and 89% of Group B animals. Average tumor burden by BLI radiance was 7.43 × 10(3) p/s/cm(2) /sr (Group A) and 1.11 × 10(4) p/s/cm(2) /sr (Group B). Radiographs and microCT demonstrated osteolysis in 100% of animals showing focal BLI signal. MicroCT demonstrated significant bone loss in both groups compared to age-matched controls but no difference between study groups. Histological analysis confirmed tumor invasion in the L5 vertebral body. These findings provide a reliable in vivo model to study isolated spinal metastases from lung cancer. Statement of Clinical Significance: The data support the notion that exposure to rhBMP-2 does not promote the growth of A549 lung cancer spine lesions. © 2016 Orthopaedic Research Society.

Abstract
BACKGROUND CONTEXT A number of studies have reported favorable surgical results for metastatic spinal tumors from various solid tumors. However, there are few data available on metastatic spinal cord compression (MSCC) from lung cancer despite its considerable frequency. PURPOSE The study aims to present the functional outcomes, survival time, and complications after surgical treatment for MSCC from non-small cell lung cancer (NSCLC). STUDY DESIGN/SETTING This is a longitudinal observational study. PATIENT SAMPLE The study includes 50 patients who had neurologic deficit and underwent surgical treatment for MSCC from NSCLC. OUTCOME MEASURES The Eastern Cooperative Oncology Group performance status (ECOG-PS), ambulatory status, overall survival, factors associated with survival time, and perioperative complications were analyzed. METHODS The postoperative changes of ECOG-PS and ambulatory status were assessed. The factors affecting postoperative ambulatory status were evaluated using logistic regression analysis. Survival time was calculated using the Kaplan-Meier method. To identify the prognostic factors, log-rank test and Cox hazards regression model were used for univariate and multivariate analyses, respectively. Major complications within postoperative 30 days and mortality rate were recorded. RESULTS The study cohort consisted of 27 males and 23 females with a mean age of 58.0±11.3 years at the time of surgery. An ECOG-PS improvement by at least one grade was observed in 33 of 50 cases (66.0%). Among 39 patients who were not ambulatory before surgery, 23 patients (59.0%) regained ambulatory ability after surgery. Patients who were preoperatively ambulant and those who underwent surgery within 72 hours from neurologic deficit had an increased chance of postoperative ambulation. The median for overall survival after surgery was 5.2 months. Five prognostic factors were identified on univariate analysis: time from neurologic deficit, responsiveness to preoperative chemotherapy, postoperative chemotherapy, postoperative ECOG-PS, and postoperative ambulatory status. Multivariate analysis revealed that time to neurologic deficit (risk ratio [RR]: 2.28, p=.023), postoperative chemotherapy (RR: 6.58, p<.001), and postoperative ECOG-PS (RR: 2.73, p=.040) were independent prognostic factors of survival time. Major complications developed in 34.0% of patients (17 of 50), and the 30-day mortality rate was 10.0% (5 of 50). CONCLUSIONS Functional improvements were observed through surgical treatment even with relatively high complication rates for MSCC from NSCLC. Earlier surgical treatment could act as an adjuvant therapy for prolonging survival by improving functional status.

Abstract
OBJECT There are few studies comparing the therapeutic efficacy between surgery combined with postoperative radiotherapy and standalone radiotherapy in treating spinal metastases of lung cancer. The aim of this clinical study was to compare the clinical and functional efficacy, quality of life, and survival outcomes between surgery combined with postoperative radiotherapy and standalone radiotherapy in treating spinal metastases of lung cancer. METHODS A retrospective analysis of clinical data from June 2008 to December 2013 was performed with 46 patients suffering spinal metastases of lung cancer. Among the studied patients, 25 patients received standalone radiotherapy (radiotherapy group), and the other 21 patients received surgery combined with postoperative radiotherapy (surgery group). Follow-up and survival time were analyzed. Pain levels of the patients were assessed by visual analogue scale (VAS) from pre-treatment to one month and three months after starting treatment. 3 months after surgery, Neurologic deficit of the patients was evaluated using Frankel Grade, and functional impairment were classified by Karnofsky Score. The quality of life (QOL) was assessed by EORTC QLQ-C30 questionnaire. RESULTS The follow-up period of the patients ranged from 2 to 25 months with the average of 8.8 months. In radiotherapy group, the mean survival was 8.5 months with median survival time of 7.8 months. In surgery group, the mean survival was 10.6 months with median survival of 8.4 months. The difference in survival times between the two groups was not statistically significant (P=0.24>0.05). From pre-treatment to one month and three months after treatment initiation, the VAS in both groups showed statistical significant improvement (One month: P<0.01 Three months: P=0.001, p<<0.01). In the surgery group, 85.7% of all patients had functionally useful Frankel Grade D or E after surgery, compared with 71.4% pre-operatively. The percentage was 72.0% in the radiotherapy group post-treatment, compared with 68.0% pre-treatment. The relief of Frankel Grade in surgical group was superior to that of the radiotherapy group (p=0.025, p<0.01). KPS score (80-100) percentages in surgery group and in radiotherapy group were increased by 19% and 13.3%, respectively. The improvement of KPS was more in the surgery group (p=0.013, P<0.01). In radiotherapy group, the EORTC QLQ-C30 score was 86.13 ± 12.11 before treatment and 68.39 ± 14.96 after treatment. In surgery group, the EORTC QLQ-C30 score was 84.09 ± 9.48 before treatment and 54.64 ± 15.17 after treatment. The improvement of patient QOL was more in the surgery group (p=0.004, p<0.01). CONCLUSION Compared with standalone radiotherapy, surgery combined with postoperative radiotherapy did not significantly prolong the survival time. However, surgery can improve pain, function and QOL of patients with spinal metastases of lung cancer.

Abstract
BACKGROUND Metastatic pathological fractures of the spine are a major problem for cancer patients; however, there is no consensus on treatment strategy. The purpose of this study was to evaluate various treatment options by analyzing their patterns for metastatic pathological fractures of the spine. METHODS In this study, 54 patients (male:female = 36:18) who were diagnosed with metastatic pathological fractures of spine were recruited. Demographic data, origin of cancer, type of treatment, and results were obtained from electronic medical records. Treatment options were divided into radiotherapy (RT), vertebroplasty (VP) or kyphoplasty (KP), operation (OP), and other treatments. Treatment results were defined as aggravation, no response, fair response, good response, and unknown. The survival time after detection of pathologic fractures was analyzed with the Kaplan-Meier method. RESULTS The mean age of the patients was 62.3 years. Hepatocellular carcinoma was the most common cancer of primary origin (n = 9), followed by multiple myeloma (n = 8). RT was the most common primary choice of treatment (n = 29, 53.7%), followed by OP (n = 13, 24.1%), and VP or KP (n = 10, 18.5%). Only 13 of 29 RT cases and 7 of 13 OP cases demonstrated a fair or good response. The mean survival time following detection of pathological spinal fractures was 11.1 months for 29 patients, who died during the study period. CONCLUSIONS RT was the most common primary choice of treatment for metastatic pathological fractures of the spine. However, the response rate was suboptimal. Although OP should be considered for the relief of mechanical back pain or neurologic symptoms, care should be taken in determining the surgical indication. VP or KP could be considered for short-term control of localized pain, although the number of cases was too small to confirm the conclusion. It is difficult to determine the superiority of the treatment modalities, hence, a common guideline for the diagnosis and treatment of metastatic pathological fractures of the spine is required.

Abstract
PURPOSE Although surgery is used increasingly as a strategy to complement treatment with radiation and chemotherapy in patients with metastatic epidural spinal cord compression (MESCC), the impact of surgery on health-related quality of life (HRQoL) is not well established. We aimed to prospectively evaluate survival, neurologic, functional, and HRQoL outcomes in patients with MESCC who underwent surgical management. PATIENTS AND METHODS One hundred forty-two patients with a single symptomatic MESCC lesion who were treated surgically were enrolled onto a prospective North American multicenter study and were observed at least up to 12 months. Clinical data, including Brief Pain Inventory, ASIA (American Spinal Injury Association) impairment scale, SF-36 Short Form Health Survey, Oswestry Disability Index, and EuroQol 5 dimensions (EQ-5D) scores, were obtained preoperatively, and at 6 weeks and 3, 6, 9, and 12 months postoperatively. RESULTS Median survival time was 7.7 months. The 30-day and 12-month mortality rates were 9% and 62%, respectively. There was improvement at 6 months postoperatively for ambulatory status (McNemar test, P < .001), lower extremity and total motor scores (Wilcoxon signed rank test, P < .001), and at 6 weeks and 3, 6, and 12 months for Oswestry Disability Index, EQ-5D, and pain interference (paired t test, P < .013). Moreover, at 3 months after surgery, the ASIA impairment scale grade was improved (Stuart-Maxwell test P = .004). SF-36 scores improved postoperatively in six of eight scales. The incidence of wound complications was 10% and 2 patients required a second surgery (screw malposition and epidural hematoma). CONCLUSION Surgical intervention, as an adjunct to radiation and chemotherapy, provides immediate and sustained improvement in pain, neurologic, functional, and HRQoL outcomes, with acceptable risks in patients with a focal symptomatic MESCC lesion who have at least a 3 month survival prognosis.

Abstract
BackgroundThe goal of preoperative embolization of spinal tumors is to improve surgical outcomes by diminishing the vascular supply to the tumor to reduce intraoperative blood loss and operative time.ObjectiveTo report our institutional experience with spinal tumor embolization and review the present literature.MethodsClinical records from January 1, 2001 to December 31, 2012 were reviewed and analyzed. Angiograms were used to calculate the percentage reduction in tumor vascularity, and relevant clinical and operative data were collected and analyzed.ResultsThirty-seven patients underwent preoperative spinal tumor embolization (24 metastatic and 13 primary lesions) and were included in the study. One complication resulted in transient lower extremity weakness and was attributed to post-embolization swelling, which fully resolved after surgical resection. The transient neurological complication rate was 1/37 (3%) and the permanent rate was 0/37 (0%). The average surgical estimated blood loss (EBL) was 1946 mL (100–7000 mL) and the average operative time was 330 min (range 164–841 min). After embolization, tumor blush was reduced by 83% on average. Average pre- and postoperative modified Rankin Scale scores were 2.10 and 1.36, respectively (p=0.03). Cases in which tumor blush was decreased by ≥90% (classes 1 or 2) after embolization had significantly less operative blood loss than those cases in which <90% (classes 3 or 4) was achieved (mean EBL 1391 vs 2296 mL, respectively, p=0.05).ConclusionsSpinal tumor embolization is a safe procedure, is associated with few complications, and may improve surgical outcomes by limiting intraoperative blood loss and reducing operative time.

Abstract
Background Surgical treatment for metastatic spine disease has been becoming more prominent with the help of technological advances and a few favorable reports on the surgery. In cases of this peculiar condition, it is necessary to establish the role of surgery and analyze the factors affecting survival. Methods From January 2011 to April 2015, 119 patients were surgically treated for metastatic spine lesions. To reduce the bias along the heterogeneous cancers, the primary cancer was confined to either the lung (n = 25) or the liver (n = 18). Forty-three patients (male, 32; female, 11; mean age, 57.5 years) who had undergone palliative surgery were enrolled in this study. Posterior decompression and fusion was performed in 30 patients (P group), and anteroposterior (AP) reconstruction was performed in 13 patients (AP group) for palliative surgery. Pre- and postoperative (3 months) pain (visual analogue scale, VAS), performance status (Karnofsky performance score), neurologic status (American Spinal Injury Association [ASIA] grade), and spinal instability neoplastic score (SINS) were compared. The survival period and related hazard factors were also assessed by Kaplan-Meier and Cox regression analysis. Results Most patients experienced improvements in pain and performance status (12.3% ± 17.2%) at 3 months postoperatively. In terms of neurologic recovery, 9 patients (20.9%) graded ASIA D experienced neurological improvement to ASIA E while the remainder was status quo. In an analysis according to operation type, there was no significant difference in patient demographics. At 12 months postoperatively, cumulative survival rates were 31.5% and 38.7% for the P group and the AP group, respectively (p > 0.05). Survival was not affected by the pre- and postoperative pain scale, Tokuhashi score, neurologic status, SINS, or operation type. Preoperative Karnofsky performance score (hazard ratio, 0.93; 95% confidence interval [CI], 0.89 to 0.96) and improvement of performance status after surgery (hazard ratio, 0.95; 95% CI, 0.92 to 0.97) significantly affected survival after operation. Conclusions There was no significant difference in surgical outcomes and survival rates between posterior and AP surgery for metastatic lesions resulting from lung and hepatocellular cancer. Preoperative Karnofsky score and improvement of performance status had a significant impact on the survival rate following surgical treatment for these metastatic spine lesions.

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

Abstract
OBJECT The number of patients with spinal tumors is rapidly increasing; spinal metastases develop in more than 30% of cancer patients during the course of their illness. Such lesions can significantly decrease quality of life, often necessitating treatment. Stereotactic radiosurgery has effectively achieved local control and symptomatic relief for these patients. The authors determined prognostic factors that predicted pain palliation and report overall institutional outcomes after spine stereotactic body radiation therapy (SBRT). METHODS Records of patients who had undergone treatment with SBRT for either primary spinal tumors or spinal metastases from June 2008 through June 2013 were retrospectively reviewed. Data were collected at the initial visit just before treatment and at 1-, 3-, 6-, and 12-month follow-up visits. Collected clinical data included Karnofsky Performance Scale scores, pain status, presence of neurological deficits, and prior radiation exposure at the level of interest. Radiation treatment plan parameters (dose, fractionation, and target coverage) were recorded. To determine the initial extent of epidural spinal cord compression (ESCC), the authors retrospectively reviewed MR images, assessed spinal instability according to the Bilsky scale, and evaluated lesion progression after treatment. RESULTS The study included 99 patients (mean age 60.4 years). The median survival time was 9.1 months (95% CI 6.9-17.2 months). Significant decreases in the proportion of patients reporting pain were observed at 3 months (p < 0.0001), 6 months (p = 0.0002), and 12 months (p = 0.0019) after treatment. Significant decreases in the number of patients reporting pain were also observed at the last follow-up visit (p = 0.00020) (median follow-up time 6.1 months, range 1.0-56.6 months). Univariate analyses revealed that significant predictors of persistent pain after intervention were initial ESCC grade, stratified by a Bilsky grade of 1c (p = 0.0058); initial American Spinal Injury Association grade of D (p = 0.011); initial Karnofsky Performance Scale score, stratified by a score of 80 (p = 0.002); the presence of multiple treated lesions (p = 0.044); and prior radiation at the site of interest (p < 0.0001). However, when multivariate analyses were performed on all variables with p values less than 0.05, the only predictor of pain at last follow-up visit was a prior history of radiation at the site of interest (p = 0.0038), although initial ESCC grade trended toward significance (p = 0.073). Using pain outcomes at 3 months, at this follow-up time point, pain could be predicted by receipt of radiation above a threshold biologically effective dose of 66.7 Gy. CONCLUSIONS Pain palliation occurs as early as 3 months after treatment; significant differences in pain reporting are also observed at 6 and 12 months. Pain palliation is limited for patients with spinal tumors with epidural extension that deforms the cord and for patients who have previously received radiation to the same site. Further investigation into the optimal dose and fractionation schedule are needed, but improved outcomes were observed in patients who received radiation at a biologically effective dose (with an a/b of 3.0) of 66.7 Gy or higher.

Abstract
Spinal metastases are increasingly becoming a focus of attention with respect to treating with locally "ablative" intent, as opposed to locally "palliative" intent. This is due to increasing survival rates among patients with metastatic disease, early detection as a result of increasing availability of spinal MRI, the recognition of the oligometastatic state as a distinct sub-group of favorable metastatic patients and the advent of stereotactic body radiotherapy (SBRT). Although conventionally fractionated radiation therapy has been utilized for decades, the rates of complete pain relief and local control for complex tumors are sub-optimal. SBRT has the advantage of delivering high total doses in few fractions (typically, 24 Gy in 1 or 2 fractions to 30-45 Gy in 5 fractions) that can be considered "ablative". With mature clinical experience emerging among early adopters, we are realizing beyond efficacy the limitations of spine SBRT. In particular, toxicities such as vertebral compression fracture, and epidural disease progression as the most common pattern of local tumor progression. As a result, the multidisciplinary evaluation of cases prior to SBRT is emphasized with the intent to identify patients who could benefit from surgical stabilization or down-staging of epidural disease. The purpose of this review is to provide an overview of the current literature with respect to outcomes, technical details for safe delivery, patient selection criteria, common and uncommon side effects of therapy, and the increasing use of minimally invasive surgical techniques that can improve both safety and local control.

Abstract
BACKGROUND CONTEXT Choosing the best surgical treatment for patients with spinal metastases remains a significant challenge for spine surgeons. There is currently no gold standard for surgical treatments. The Aarhus Spinal Metastases Algorithm (ASMA) was established to help surgeons choose the most appropriate surgical intervention for patients with spinal metastases. PURPOSE The purpose of this study was to evaluate the clinical outcome of stratified surgical interventions based on the ASMA, which combines life expectancy and the anatomical classification of patients with spinal metastases to inform surgical decision making. STUDY DESIGN/SETTING This is a retrospective study based on a prospective database. PATIENT SAMPLE A consecutive series of 515 spinal metastatic patients who underwent surgically treatment from December 1992 to June 2012 in Aarhus University Hospital were included prospectively and analyzed in detail retrospectively. OUTCOME MEASURES Survival time after surgery was determined for all patients. Neurological function was assessed using the Frankel score preoperatively and postoperatively (at the time of discharge). Complete outcome data were retrieved in 97.5% of this cohort. METHODS Patients with spinal metastases were identified from an institutional database that prospectively collected data since 1992. Survival status data were obtained from a national registry. Neurological function was determined from the same institutional database or local Electronic Patient Journal system. Surgeons evaluated and classified patients into five surgical groups preoperatively by using the revised Tokuhashi score (TS) and the Tomita anatomical classification (TC). RESULTS The overall median survival time of the cohort was 6.8 (95% confidence interval: 6.1-7.9) months. The median survival times in the five surgical groups determined by the ASMA were 2.1 (TS 0-4, TC 1-7), 5.1 (TS 5-8, TC 1-7), 12.1 (TS 9-11, TC 1-7 or TS 12-15, TC 7), 26.0 (TS 12-15, TC 4-6), and 36.0 (TS 12-15, TC 1-3) months. The 30-day mortality rate was 7.5%. Postoperative neurological function was maintained or improved in 469 patients (92.3%). Overall reoperation rate was 13.5%, commonly because of postoperative hematoma and new limb weakness. CONCLUSIONS The ASMA recommends at least two surgical options for a particular patient by determining the preoperative life expectancy and anatomical classification of the spinal metastases. This algorithm could help spine surgeons to discriminate the risks of surgeries. The ASMA provides a tool to guild surgeons to evaluate the spinal metastases patients, select potential optimal surgery, and avoid life-threatening risks.

Abstract
OBJECTIVE Surgical treatment of spinal metastasis is generally a palliative procedure. Although minimally invasive surgical (MIS) techniques are supposedly less morbid than open techniques, there is a lack of stratification of MIS techniques based on anticipated longevity. A simple stratification into three percutaneous surgical techniques based on modified Tokuhashi score is here proposed. METHODS Patients recommended for spinal surgery for metastatic spinal disease between 2009 and 2012 and operated on by the senior author (RJM) were retrospectively reviewed. One of three MIS techniques was offered based on estimated survival using a modified Tokuhashi score. Technique #1 is suitable for patients with predicted short longevity (<6 months). Using a mini-open midline or paramedian decompression and percutaneous screw fixation, the goal here is for rapid mobilization and minimization of hospitalization. Technique #2 is suitable for patients with predicted medium longevity (6-12 months). They are suitable for decompression and/or cement vertebral body replacement and a two levels stabilization. Technique #3 is suitable for patients with predicted long term survival survival (>12 months). In these patients, the primary goal of surgery is a wide local or marginal resection of tumor, decompression of the neurological elements and a robust stabilization construct. They are suitable for an open 360°decompression, vertebral body reconstruction and a multilevel stabilization. RESULTS The study included eight patients with a mean age of 59 years (range, 36-72 years). Mean modified Tokuhashi score was 10 (range, 7-13) with three patients in the short term, two in the medium term and three in the long term survival category. Mean blood loss was 700 mL (range, 100-1200 mL), mean operating time 280 min (range, 120-360 min) and length of stay in the hospital was on average 13 days (range, 3-30 days). CONCLUSION The authors present three minimally invasive technique options for the management of spinal metastatic disease corresponding to three clinical prognostic categories. In this small series, MIS techniques resulted in speedy recovery, minimal morbidity and no mortality.

Abstract
OBJECT Spinal metastasis is common in patients with cancer. About 70% of symptomatic lesions are found in the thoracic region of the spine, and cord compression presents as the initial symptom in 5%-10% of patients. Minimally invasive spine surgery (MISS) has recently been advocated as a useful approach for spinal metastases, with the aim of decreasing the morbidity associated with more traditional open spine surgery; furthermore, the recovery time is reduced after MISS, such that postoperative chemotherapy and radiotherapy can begin sooner. METHODS Two series of oncological patients, who presented with acute myelopathy due to vertebral thoracic metastases, were compared in this study. Patients with complete paraplegia for more than 24 hours and with a modified Bauer score greater than 2 were excluded from the study. The first group (n = 23) comprised patients who were prospectively enrolled from May 2010 to September 2013, and who were treated with minimally invasive laminotomy/laminectomy and percutaneous stabilization. The second group (n = 19) comprised patients from whom data were retrospectively collected before May 2010, and who had been treated with laminectomy and stabilization with traditional open surgery. Patient groups were similar regarding general characteristics and neurological impairment. Results were analyzed in terms of neurological recovery (American Spinal Injury Association grade), complications, pain relief (visual analog scale), and quality of life (European Organisation for Research and Treatment of Cancer [EORTC] QLQ-C30 and EORTC QLQ-BM22 scales) at the 30-day follow-up. Operation time, postoperative duration of bed rest, duration of hospitalization, intraoperative blood loss, and the need and length of postoperative opioid administration were also evaluated. RESULTS There were no significant differences between the 2 groups in terms of neurological recovery and complications. Nevertheless, the MISS group showed a clear and significant improvement in terms of blood loss, operation time, and bed rest length, which is associated with a more rapid functional recovery and discharge from the hospital. Postoperative pain and the need for opioid administration were also significantly less pronounced in the MISS group. Results from the EORTC QLQ-C30 and QLQ-BM22 scales showed a more pronounced improvement in quality of life at follow-up in the MISS group. CONCLUSIONS In the authors' opinion, MISS techniques should be considered the first choice for the treatment for patients with spinal metastasis and myelopathy. MISS is as safe and effective for spinal cord decompression and spine fixation as traditional surgery, and it also reduces the impact of surgery in critical patients. However, further studies are needed to confirm these findings.

Abstract
OBJECT Spinal metastases most commonly affect the vertebral bodies of the spinal column, and spinal cord compression is an indication for surgery. Commonly, an open posterior approach is employed to perform a transpedicular costotransversectomy or lateral extracavitary corpectomy. Because of the short life expectancies in patients with metastatic spinal disease, decreasing the morbidity of surgical treatment and recovery time is critical. One potential approach to decreasing morbidity is utilizing minimally invasive surgery (MIS). Although significant advances have been made in MIS of the spine, data supporting the utility of MIS are still emerging. This study compared outcomes of patients who underwent mini-open versus traditional open transpedicular corpectomy for spinal metastases in the thoracic spine. METHODS A consecutive cohort from 2006 to 2013 of 49 adult patients who underwent thoracic transpedicular corpectomies for spinal metastases was retrospectively identified. Patients were categorized into one of 2 groups: open surgery and mini-open surgery. Mini-open transpedicular corpectomy was performed with a midline facial incision over only the corpectomy level of interest and percutaneous instrumentation above and below that level. The open procedure consisted of a traditional posterior transpedicular corpectomy. Chi-square test, 2-tailed t-test, and ANOVA models were employed to compare perioperative and follow-up outcomes between the 2 groups. RESULTS In the analysis, there were 21 patients who had mini-open surgery and 28 patients who had open surgery. The mean age was 57.9 years, and 59.2% were male. The tumor types encountered were lung (18.3%), renal/bladder (16.3%), breast (14.3%), hematological (14.3%), gastrointestinal tract (10.2%), prostate (8.2%), melanoma (4.1%), and other/unknown (14.3%). There were no significant intergroup differences in demographics, comorbidities, neurological status (American Spinal Injury Association [ASIA] grade), number of corpectomies performed, and number of levels instrumented. The open group had a mean operative time of 413.6 minutes, and the mini-open group had a mean operative time of 452.4 minutes (p = 0.329). Compared with the open group, the mini-open group had significantly less blood loss (917.7 ml vs. 1697.3 ml, p = 0.019) and a significantly shorter hospital stay (7.4 days vs. 11.4 days, p = 0.001). There was a trend toward a lower perioperative complication rate in the mini-open group (9.5%) compared with the open group (21.4%), but this was not statistically significant (p = 0.265). At follow-up, there were no significant differences in ASIA grade (p = 0.342), complication rate after the 30-day postoperative period (p = 0.999), or need for surgical revision (p = 0.803). The open approach had a higher overall infection rate of 17.9% compared with that in the mini-open approach of 9.5%, but this was not statistically significant (p = 0.409). CONCLUSIONS The mini-open transpedicular corpectomy is associated with less blood loss and shorter hospital stay compared with open transpedicular corpectomy. The mini-open corpectomy also trended toward lower infection and complication rates, but these did not reach statistical significance.

Abstract
BACKGROUND CONTEXT The incidence of metastatic spinal cord compression (MSCC) is increasing, paralleling increasing life expectancy of patients. However, management of MSCC and relevance of scoring systems remain controversial. PURPOSE The aims of our study were to analyze the feasibility and outcomes of spinal surgery, to identify prognostic factors for survival, and to assess the accuracy of scoring systems in patients with malignancies associated with MSCC. STUDY DESIGN Retrospective analysis of all patients with MSCC operated in our institution. METHODS Outcomes of surgery, prognostic factors for survival, and relevance of Tomita and Tokuhashi scores were investigated. RESULTS One hundred forty-eight patients were included: 66% were hyperalgic (pain score >6) and Frankel score (FS) was decreased in 49%. Seventy-three percent of patients had laminectomy with spinal fixation. After surgery, pain decreased in 75% of cases, FS was improved in 31%, and 92% of patients were ambulatory. Postoperative complication rate was 16%. Median overall survival (OS) was 8.9 months (95% confidence interval, 4.4-13). Only Tokuhashi score was relevant, but predictive accuracy of survival was just 51%. In univariate analyses, hyperalgia (p=.001), primary tumor site, extrabone metastases (p<.001), Karnofsky performance status (KPS) less than 70 (p<.001), poor American Society of Anesthesiologist (ASA) score (p<.001) or FS (p=.01), and absence of postoperative chemotherapy (p<.001) were associated with shorter OS. In multivariate analysis, only extrabone metastases (p=.004), KPS (p=.001), and ASA score (p=.007) remained significantly associated with OS. CONCLUSIONS Surgery for MSCC is associated with limited morbidity, improved autonomy, and pain relief. Usual scores do not seem relevant, whereas ASA score, KPS, and extrabone metastases are significantly associated with OS.

Abstract
OBJECT Clinical outcomes in patients with primary spinal osteochondromas are limited to small series and sporadic case reports. The authors present data on the first long-term investigation of spinal osteochondroma cases. METHODS An international, multicenter ambispective study on primary spinal osteochondroma was performed. Patients were included if they were diagnosed with an osteochondroma of the spine and received surgical treatment between October 1996 and June 2012 with at least 1 follow-up. Perioperative prognostic variables, including patient age, tumor size, spinal level, and resection, were analyzed in reference to long-term local recurrence and survival. Tumor resections were compared using Enneking appropriate (EA) or Enneking inappropriate surgical margins. RESULTS Osteochondromas were diagnosed in 27 patients at an average age of 37 years. Twenty-two lesions were found in the mobile spine (cervical, thoracic, or lumbar) and 5 in the fixed spine (sacrum). Twenty-three cases (88%) were benign tumors (Enneking tumor Stages 1-3), whereas 3 (12%) exhibited malignant changes (Enneking tumor Stages IA-IIB). Sixteen patients (62%) underwent en bloc treatment-that is, wide or marginal resection-and 10 (38%) underwent intralesional resection. Twenty-four operations (92%) followed EA margins. No one received adjuvant therapy. Two patients (8%) experienced recurrences: one in the fixed spine and one in the mobile spine. Both recurrences occurred in latent Stage 1 tumors following en bloc resection. No osteochondroma-related deaths were observed. CONCLUSIONS In the present study, most patients underwent en bloc resection and were treated as EA cases. Both recurrences occurred in the Stage 1 tumor cohort. Therefore, although benign in character, osteochondromas still require careful management and thorough follow-up.

Abstract
Objective To report a minimally invasive treatment option using percutaneous pedicle screw fixation with adjuvant treatment for metastatic thoraco-lumbar and lumbar spinal tumors. Methods This is a retrospective study of charts of patients with spinal metastases. All were older than 18 years of age and were considered to have more than 3 months of life expectancy. The patients had single or two level lesions, and compression fracture or impending fracture. Exclusion criterion was metastasis showing severe epidural compression with definite neurological symptoms. Usually spinal segments from one level above to below pathology were stabilized. Visual analog scale (VAS) score for pain assessment and Frankel scale for neurological deficit were used, while pre- and post-operative performance status was evaluated using the Eastern Cooperative Oncology Group (ECOG). Results Twelve patients (nine men, three women; median age 54.29 years) underwent surgery. All patients presented with back pain with/without radicular pain. There were no early complications and perioperative mortalities. Following surgery, a significant difference between average pre- and post-operative VAS scores was found (p=0.003). Overall, 91.8% of patients (11/12) experienced improvement in their ECOG score post-operatively. The mean ambulation time was 196.9 days [95% confidence interval (CI), 86.2-307.6 days; median, 97 days]. During follow-up, nine patients died and the mean overall survival time in enrolled twelve patients was 249.9 days (95% CI, 145.3-354.4 days; median, 176 days). Conclusion Minimally invasive treatment using percutaneous pedicle screw fixation with adjuvant treatment is a good alternative treatment option for potential instability of the thoraco-lumbar and lumbar spinal metastasis.

Abstract
STUDY DESIGN The study design of this paper is a systematic review of literature published in the recent 10 years. OBJECTIVE It is the objective of this paper to compare the clinical efficacy and safety of minimal access (MIS) spinal surgery and open spinal surgery for treating painful spine metastasis. METHODS Two research questions below were determined through a consensus among a panel of spine experts. A systematic review of literature on spinal surgery was conducted by searching PubMed with a combination of keywords including "metastatic", "metastasis", "metastases", "spinal", and "spine". Independent reviewers selected the articles for analysis after screening the titles, abstracts, and full texts, then extracted data and graded the quality of each paper according to the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) criteria. Specific clinical questions were as follows: 1. In patients with spine metastatic disease, what is the impact of different surgical approaches (MIS versus open) on pain relief and functional outcome? 2. In patients with metastatic disease, what is the impact of different surgical approaches (MIS versus open) on local recurrence, survive rate, and complication? RESULTS A total of 1,076 abstracts were identified using various keywords. 5 prospective (level II) and 12 retrospective articles (level III) were eligible for inclusion, involving a total of 979 cases of spine metastasis. There were 345 cases in 8 studies regarding the clinical evaluation of MIS spinal surgery and 634 cases in 9 studies regarding the clinical evaluation of open spinal surgery for spine metastasis. CONCLUSION Both open spinal surgery and MIS seem to achieve the improvement of pain and neurological dysfunction through decompression and stabilization for patients with spine metastasis, but open surgery may involve more major complications with a trend of lower survival rates and higher recurrence rates compared to MIS.

Abstract
Objective The cervicothoracic junction (CTJ) is a biomechanically and anatomically complex region that has traditionally posed problems for surgical access. In this retrospective study, we describe our clinical experiences of the treatment of metastatic spinal tumors at the CTJ and the results. Methods From June 2006 to December 2011, 23 patients who underwent surgery for spinal tumors involving the CTJ were enrolled in our study. All of the patients were operated on through the posterior approach, and extent of resection was classified as radical, debulking, and simple neural decompression. Adjuvant radiation therapy (RT) was also considered. Visual analog scale score for pain assessment and Medical Research Council (MRC) grade for motor weakness were used, while pre- and post-operative performance status was evaluated using the Eastern Cooperative Oncology Group (ECOG). Results Almost all of the patients were operated using palliative surgical methods (91.3%, 21/23). Ten complications following surgery occurred and revision was performed in four patients. Of the 23 patients of this study, 22 showed significant pain relief according to their visual analogue scale scores. Concerning the aspect of neurological and functional recovery, mean MRC grade and ECOG score was significantly improved after surgery (p<0.05). In terms of survival, radiation therapy had a significant role. Median overall survival was 124 days after surgery, and the adjuvant-RT group (median 214 days) had longer survival times than prior-RT (63 days) group. Conclusion Although surgical procedure in CTJ may be difficult, we expect good clinical results by adopting a palliative posterior surgical method with appropriate preoperative preparation and postoperative treatment.

Abstract
The skeletal system is the third most common site of metastases after the lung and liver. Within the skeletal system, the vertebral column is the most common site of metastases, and 8% to 15% of vertebral metastases are in the cervical spine, consisting, anatomically and biomechanically, of the occipitocervical junction, subaxial spine, and cervicothoracic junction. The vertebral body is more commonly affected than the posterior elements. Nonsurgical management techniques include radiation therapy (stereotactic and conventional), bracing, and chemotherapy. Surgical techniques include percutaneous methods, such as vertebroplasty, and palliative methods, such as decompression and stabilization. Surgical approach depends on the location of the tumor and the goals of the surgery. Appropriate patient selection can lead to successful surgical outcomes by restoring spinal stability and improving quality of life.

Abstract
A fifty-year-old female non-smoker with no other specific medical history visited our institute. She complained of axial back pain with no other neurological deficit. Chest X-ray, chest computed tomography (CT) scan, CT-guided needle aspiration biopsy, whole-body positron emission tomography, spine CT and spine magnetic resonance image findings suggested NSCLC with epidermal growth factor receptor (EGFR) mutation, multiple brain metastases, and two isolated metastases to the T3 and L3 vertebral bodies. She underwent chemotherapy with gefitinib (Iressa™) for NSCLC and gamma knife surgery for multiple brain metastases. We performed a two-staged, total en bloc spondylectomy of the T3 and L3 vertebral bodies based on several good prognostic characteristics, such as the lack of metastases to the appendicular bone, good preoperative performance status, and being an excellent responder (Asian, never-smoker and adenocarcinoma histology) to EGFR inhibitors. Improved axial back pain after the surgery enabled her to walk with the aid of a thoracolumbosacral orthosis brace on the third postoperative day. Her Karnofsky performance status score (KPS) was 90 at the time of discharge and has been maintained to date 3 years after surgery. In selected NSCLC patients with good prognostic characteristics, we suggest that locally curative treatment such as total en bloc spondylectomy or radiosurgery should be emphasized to achieve longer term survival for the selected cases.

Abstract
BACKGROUND CONTEXT Spinal cord compression and fracture are possible complications of spine metastasis and multiple myeloma. Prompt diagnosis and treatment of threatening lesions are likely to reduce the frequency of these dreaded complications. PURPOSE To evaluate the proportion of neoplastic spine lesions operated on emergency. STUDY DESIGN Retrospective study. PATIENT SAMPLE All patients who underwent palliative surgery for the treatment of a neoplastic spine lesion in our institution between 2005 and 2012. OUTCOME MEASURES Percentage of patients who underwent surgery as an emergency for acute fracture or rapid neurological decline. METHODS We retrospectively reviewed the data of all patients who underwent palliative surgery for the treatment of a neoplastic spine lesion from solid cancer or multiple myeloma, in our institution between January 2005 and December 2012. The study was supported by grant from our institution. RESULTS A total of 317 patients were included in the study. There were 166 men and 151 women and the mean age was 57.97 years (range 26-88; SD 12.45). The cancer was known for 224 patients, while the lesion revealed the disease for the other 93 patients. The percentage of patients with known cancer operated as an emergency in our institution decreased significantly between 2005 and 2012 (p = 0.0006). CONCLUSION Due to the variability of clinical and radiological presentations, best care requires a truly multidisciplinary approach, to offer each patient a prompt and individualized treatment option, which is likely to reduce the incidence of emergency surgeries.

Abstract
PURPOSE Up to 75% of patients with prostate cancer experience metastatic bone disease, which leads to an increased risk for skeletal-related events (SREs) including pathological bone fracture, spinal cord compression, and hypercalcemia of malignancy. Our objective was to systematically review the literature on the impact of SREs on quality of life (QOL), morbidity, and survival with a primary focus on the impact of SREs on pain in prostate cancer patients. METHODS We searched PubMed, limiting to peer-reviewed English-language human studies published in 2000-2010. The search was based on the US Food and Drug Administration and European Medicines Agency definition of an SRE, which includes pathologic fracture, spinal cord compression (SCC), hypercalcemia of malignancy, and radiotherapy or surgery to bone resulting from severe bone pain. RESULTS A total of 209 articles were screened, of which 173 were excluded, and 36 were included in this review. Patients with SREs had more pain and worse survival compared with no SREs. Pathologic bone fractures worsened QOL and were associated with shorter survival. Radiation therapy of SCC alleviated pain and improved morbidity. SCC was associated with decreases in patient survival. Radiation therapy and surgery to bone improved pain. CONCLUSIONS Specific SREs are associated with worse outcomes, including increased pain, poorer QOL, morbidity, and survival. Treatment of SREs is associated with improved pain, although there remains a need for more effective treatment of SREs in prostate cancer patients.

The incidence and patterns of hardware failure after separation surgery in patients with spinal metastatic tumors. Spine J 2014; 14:1850-9. [PMID: 24216397 DOI: 10.1016/j.spinee.2013.10.028] [Citation(s) in RCA: 76] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2013] [Revised: 08/26/2013] [Accepted: 10/22/2013] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Spine metastases occur frequently in patients with cancer. A variety of surgical approaches, including anterior transcavitary, lateral extracavitary, posterolateral, and/or combined techniques are used for spinal cord decompression and restoration of spinal stability. The incidence of symptomatic hardware failure is unknown for the majority of these approaches. PURPOSE The purpose of this study was to determine the incidence of symptomatic hardware failure and the associated risk factors in patients with metastatic epidural spinal cord compression (MESCC). STUDY DESIGN/SETTING This was a retrospective study. PATIENT SAMPLE The current series analyzes a cohort of 318 patients who underwent separation surgery, which involves single-stage posterolateral decompression and posterior segmental instrumentation for MESCC. OUTCOME MEASURES The event of interest was hardware failure; the competing event was death resulting from any cause. All patients were monitored for survival analysis. A competing risk analysis was conducted to examine univariately a number of potential risk factors associated with hardware failure, including junctional level, gender, construct length, and the presence or absence of prior chest wall resection. METHODS A retrospective analysis and chart review were performed for 318 consecutive patients who underwent posterolateral decompression and posterior screw-rod fixation without supplemental anterior fixation from March 2004 to June 2011 at our institution. The median follow-up time for survivors without hardware failure was 399 days (range, 9-2,828), with a mean operative time of 3 hours. A total of 78% of patients died during the 7-year study period. RESULTS Of the 318 patients, nine (2.8%) exhibited signs and symptoms of hardware failure and required revision of the instrumentation. Patients with chest wall resection and those with initial construct length greater than six contiguous spinal levels exhibited a statistically significantly higher risk of symptomatic hardware failure than their counterparts. We observed a trend toward an increased risk of failure in women compared with men (p=.09). CONCLUSIONS The incidence of hardware failure is low in patients with MESCC who undergo posterolateral decompression and posterior screw-rod instrumentation. Moreover, the short operative time and low morbidity profile associated with this approach make it a reliable and acceptable method for the surgical treatment of MESCC. Patients with constructs spanning six or more levels or those with prior chest wall resection are at higher risk for instrumentation failure.

Abstract
OBJECTIVE Metastatic spinal disease requires a multidisciplinary approach with advanced surgical techniques which improve longevity and the quality of life. The purpose of this study is to compare the surgical outcomes and perioperative complications and mortality among en bloc, debulking, and palliative surgeries in patients with spinal metastasis. METHODS From 2005 to 2010, 200 patients who underwent surgical treatment for spinal metastases were enrolled retrospectively. Clinical analysis included primary cancer type, survival following the diagnosis of cancer, postoperative survival, Tokuhashi score, postoperative functional status, postoperative complications and mortality depending on the surgery type. Enrolled patients were divided into 3 groups: en bloc excision, debulking curettage, and palliative surgery. Surgical outcomes including perioperative complication and mortality were compared based on the surgery type. RESULTS The mean age was 59.9 years (range 21-87). The major types of primary cancer were lung (42 cases), liver (27 cases), and colorectal cancer (27 cases). 62 surgeries (31.0%) were en bloc excisions, 82 (41.0%) were debulking, and 56 (28.0%) were palliative operations. The mean Tokuhashi score was 9.2±3.3 in the en bloc group, 7.2±3.0 in the debulking group and 8.2±2.6 in the palliative group (p=0.001, ANOVA). Mean postoperative survivals were 17.9±22.1 months in the en bloc group, 7.0±11.7 months in the debulking group and 8.5±10.8 months in the palliative group (p=0.022, ANOVA). There were 8 (12.9%) postoperative complications in the en bloc group, 17 (20.7%) in the debulking group, and 8 (14.3%) in the palliative group (p=0.016, chi-square). Three patients (4.8%) in the en bloc group had multiple complications, as did 5 (6.1%) in the debulking group and 2 (3.6%) in the palliative group (p=0.925, chi-square). Among 21 total perioperative deaths, 6 (28.6%) were in the en bloc group, 10 (47.6%) in the debulking group, and 5 (23.8%) in the palliative group (p=0.618, chi-square). CONCLUSION Postoperative complications were most common in the debulking group compared to the en bloc and palliative groups, despite the fact that there were no differences in the improvement of neurologic deficits after surgery. Therefore, selecting the proper surgery based on the patients' symptoms and neurologic status is of great significance in the planning stage of the surgery.

Abstract
Background The axial skeleton is a common site for primary tumors and metastatic disease, with metastatic disease being much more common. Primary and metastatic spinal tumors have a diverse range of aggressiveness, ranging from benign lesions to highly infiltrative malignant tumors. Methods The authors reviewed the results of articles describing the treatment and outcomes of patients with metastatic disease or primary tumors of the spinal column. Results En bloc resection is the mainstay of treatment for malignant primary tumors of the spinal column. Intralesional resection is generally appropriate for benign primary tumors. Low-quality evidence supports the use of chemotherapy in select primary tumors; however, radiation therapy is often used for incompletely resected or unresectable lesions. Surgical considerations for the treatment of metastatic disease are more nuanced and require that the health care professional consider patient performance status and the pathology of the primary tumor. Conclusions The treatment of metastatic and primary tumors of the spinal column requires a multidisciplinary approach in order to offer patients the best opportunity for long-term survival.

Abstract
Neurologic complications of lung cancer are a frequent cause of morbidity and mortality. Tumor metastasis to the brain parenchyma is the single most common neurologic complication of lung cancer, of any histologic subtype. The goal of radiation therapy and in some cases surgical resection for patients with brain metastases is to improve or maintain neurologic function, and to achieve local control of the brain lesion(s). Metastasis of lung cancer to the spinal epidural space requires urgent evaluation and treatment. Early diagnosis and modern surgical and radiotherapy techniques improve neurologic outcome for most patients. Leptomeningeal metastasis is a less common but ominous occurrence in patients with lung cancer. Lung carcinomas can also occasionally metastasize to the brachial plexus, skull base, dura, or pituitary. Paraneoplastic neurologic disorders are uncommon but important complications of lung carcinoma, and are generally the presenting feature of the tumor. Paraneoplastic disorders are believed to be caused by an autoimmune humoral or cellular attack against shared "onconeural" antigens. The most frequent paraneoplastic disorders in patients with lung cancer are Lambert-Eaton myasthenic syndrome, and multifocal paraneoplastic encephalomyelitis, both mainly occurring in association with small-cell lung carcinoma. There is a variety of other paraneoplastic disorders affecting the central and peripheral nervous systems. Some affected patients have a good neurologic outcome, while others are left with severe permanent neurologic disability.

Abstract
Many studies have evaluated patient satisfaction surgeries for primary cancers. No studies have evaluated patient satisfaction in metastasectomies. The authors examined patient and family satisfaction with en bloc total resection of solitary spinal metastases and evaluated the factors that correlated with dissatisfaction. From 1998 to 2010, total en bloc spondylectomy (TES) was performed in 110 patients with solitary spinal metastases at the authors' institution. Questionnaires were sent by mail to 110 patients and their families in January 2012. Questionnaire included a subjective assessment of the results of surgery and the following questions: (1) Would you have the surgery again if you were returned to your presurgery status? and (2) Do you feel that you are a patient without cancer? To identify factors for dissatisfaction with the outcomes of TES, univariate and multivariate analyses were performed. Questionnaires were successfully delivered to 104 patients and their families. Responses were collected from 47 patients and 61 family members. Forty-five patients were very satisfied or satisfied with the outcomes of TES, and the other 2 were neutral. Fifty-four family members were very satisfied or satisfied, 5 were neutral, and 2 were dissatisfied. Forty-five patients indicated they would have the surgeries again. Thirteen patients indicated that they felt like patients without cancer. In multivariate analysis, patient death less than 2 years postoperatively and major postoperative complications were associated significantly with dissatisfaction.

Abstract
The current operative approaches and technical possibilities in the operative treatment of spinal metastases are manifold which enables an individual operative strategy adapted to the patient's condition. Maintaining quality of life is the primary goal in the treatment of these patients. The therapeutic goals, such as pain control, avoidance of neurological deficits and the achievement of spinal stability have to be attained with as little morbidity as possible. From this perspective the available operative techniques ranging from minimally invasive approaches to complex reconstructive surgery will be addressed and discussed in this article.

Abstract
BACKGROUND Spinal metastases of the second cervical vertebra are a subset of tumors that are particularly difficult to address surgically. Previously described techniques require highly morbid circumferential dissection posterior to the pharynx for resection and reconstruction. OBJECTIVE To perform a biomechanical analysis of instrumented reconstruction configurations used after axial spondylectomy and to demonstrate safe use of a novel construct in a patient case report. METHODS Several different published and novel reconstruction configurations were inserted into 7 occipitocervical spines that underwent axial spondylectomy. A biomechanical analysis of the stiffness of the constructs in flexion and extension, lateral bending, and rotation was performed. A patient then underwent a posterior-only approach for axial spondylectomy and circumferential reconstruction. RESULTS Biomechanical analysis of different constructs demonstrated that anterior column reconstruction with bilateral cages spanning the C1 lateral mass to the C3 facet in combination with occipitocervical instrumentation was superior in flexion-extension and equivalent in lateral bending and rotation to currently used constructs. The patient in whom this construct was placed via a posterior-only approach for axial spondylectomy and instrumentation remained at neurological baseline and demonstrated no recurrence of local disease or failure of instrumentation to date. CONCLUSION When C1 lateral mass to C3 facet bilateral cage plus occipitocervical instrumentation is compared with existing anterior and posterior constructs, this novel reconstruction is biomechanically equivalent if not superior in performance. In a patient, the posterior-only approach for C2 spondylectomy with the novel reconstruction was safe and durable and avoided the morbidity of the anterior approach.
