Abstract
OBJECTIVE To describe a novel surgical approach in which myelotomy was performed lateral to the dorsal root entry zone (LDREZ), for the treatment of lateral or ventrolateral spinal intramedullary glioma. METHODS This study reviewed six patients with lateral or ventrolateral spinal intramedullary glioma who received surgical treatments by using myelotomy technique of LDREZ approach. The patient's clinical characteristics, magnetic resonance imaging (MRI) results, and follow-up outcomes were analyzed. The neurological function of patients before and after operation was assessed based on the Frankel scale system. The anatomical feasibility, surgical techniques, advantages and disadvantages of LDREZ approach were analyzed. RESULTS Myelotomy technique of LDREZ approach was employed in all 6 patients. Gross total resections were achieved in 4 patients, and 2 patients with astrocytoma (case 2, 6) underwent partial removal. The perioperative recovery was all smooth and all the patients were discharged on schedule. All the patients who suffered from neuropathic pain were relieved. After surgery, neurological function remained unchanged in 3 patients. 2 patients improved from Frankel grade B to C, and 1 patient deteriorated from Frankel grade D to C immediately after surgery and returned to Frankel grade D at 3 months follow-up. Regarding to the poor prognosis of high-grade glioma, the two cases with WHO IV glioma didn't achieve long survival. CONCLUSION LDREZ approach is feasible and safe for the surgical removal of lateral or ventrolateral spinal gliomas. This approach can provide a direct pathway to lateral or ventrolateral spinal gliomas with minimal damage to normal spinal cord.

Abstract
A new entity of gliomas, named "diffuse midline glioma (DMG), H3K27M mutant (grade IV)," which represents a specific molecular profile, was introduced to the World Health Organization (WHO) classification 2016 of central nervous system tumors. Many midline localizations have been described for this glioma, and mainly the hypothalamus, pons, thalamus, and spinal cord are sites of predilection in pediatric and young adult patients. We report the case of spinal intramedullary DMG, H3K27M mutant (WHO grade IV), that showed an unusual presentation with multiple vertebral metastases.

Abstract
OBJECTIVE Knowledge on the management of spinal cord astrocytoma (SCA) remains scarce. Here, the authors constructed and validated a predictive nomogram, often used for individualized prognosis and evaluations, to estimate cancer-specific survival (CSS) and overall survival (OS) for patients with SCA. METHODS Epidemiological characteristics were compared between low-grade SCA (LGSCA) and high-grade SCA (HGSCA) patients from the Surveillance, Epidemiology, and End Results (SEER) database. Risk factors for CSS and OS were determined using univariate and multivariate analyses and Kaplan-Meier curves. A nomogram was developed to individually predict the 3-, 5-, and 10-year CSS and OS rates. The clinical usefulness of the nomogram was assessed using calibration plots, the concordance index (C-index), and time-dependent receiver operating characteristic curves. RESULTS A total of 468 LGSCA and 165 HGSCA patients were eligible for inclusion. LGSCA and HGSCA patients demonstrated differences in age, tumor extension, insurance status, adjuvant treatment, and survival. Multivariate analysis demonstrated that in the LGSCA group, tumor extension, surgery type, and adjuvant therapy were individually associated with CSS. The distance of tumor extension and WHO grade were individually associated with CSS in the HGSCA group. The prognostic variables were further demonstrated using the Kaplan-Meier method, which also suggested that adjuvant treatment provided no advantage to HGSCA patients. A nomogram was constructed, and the C-index for CSS was 0.84 by internal validation (95% CI 0.79-0.90). CONCLUSIONS This research suggests that the distance of tumor extension, type of surgery, and adjuvant therapy are significant risk factors for CSS using multivariate analysis in the LGSCA group. Adjuvant treatment provided no advantages for CSS or OS in patients with HGSCAs. The nomogram may be clinically useful to healthcare providers.

Abstract
Background Optic nerve astrocytomas (ONAs) are neurological neoplasms in the central nervous system (CNS), and they have the highest incidence rate among all the tumor types in the visual pathway. In this study, we conducted a Surveillance, Epidemiology, and End Results (SEER) -based research to explore the demographic, survival, and prognostic factors of patients diagnosed with ONAs. Methods Utilizing the SEER database, we retrospectively evaluated data of patients diagnosed with ONAs of all ages from 1984 to 2016. We used the Student’s t distribution to test variables of patients and various characteristics, and Kaplan-Meier curve to illustrate overall survival (OS) with 95.0% confidence intervals (CIs). We also performed univariate and multivariate analyses to evaluate various variables’ validity on overall survival. Results A total of 1004 cases were analyzed, and revealed that age (P<0.001, hazard ratio (HR) = 8.830, 95% CI: 4.088–19.073), tumor grade (P<0.001, HR = 1.927, 95% CI: 1.516–2.450), diagnostic confirmation (P<0.001, HR = 2.444, 95% CI: 1.632–3.660), and histology type (P = 0.046, HR = 1.563, 95% CI: 1.008–2.424) of the tumor were associated with decreased survival. Conclusions From this large, comparative study of ONAs, we found that younger age may be considered as a protective indicator, while high-grade astrocytic tumors have a worse prognosis. We also found that diagnostic confirmation and tumor grade were independent prognostic factors in this patient population.

Abstract
Pediatric glioblastoma multiforme (GBM) involving the spine is an aggressive tumor with a poor quality of life for patients. Despite this, there is only a limited number of reports describing the outcomes of pediatric spinal GBMs, both as primary spinal GBMs and metastases from an intracranial tumor. Here, we performed an individual patient meta-analysis to characterize factors affecting prognosis of pediatric spinal GBM. MEDLINE, Embase, and the Cochrane databases were searched for published studies on GBMs involving the spine in pediatric patients (age ≤ 21 years old). Factors associated with the survival were assessed with multi-factor ANOVAs, Cox hazard regression, and Kaplan-Meier analyses. We extracted data on 61 patients with spinal GBM from 40 studies that met inclusion criteria. Median survival was significantly longer in the primary spinal GBM compared that those with metastatic GBM (11 vs 3 months, p < 0.001). However, median survival of metastatic GBM patients was 10 months following diagnosis of their primary brain tumor, which was not different from that of primary spinal GBM patients (p = 0.457). Among primary spinal GBM patients, chemotherapy (hazard ratio (HR) = 0.255 [0.106-0.615], p = 0.013) and extent of resection (HR = 0.582 [0.374-0.905], p = 0.016) conferred a significant survival benefit. Younger age (less than 14 years) was associated with longer survival in patients treated with chemotherapy than those who did not undergo chemotherapy (β = - 1.12, 95% CI [- 2.20, - 0.03], p < 0.05). In conclusion, survival after presentation of metastases from intracranial GBM is poor in the pediatric population. In patients with metastatic GBM, chemotherapy may have provided the most benefit in young patients, and its efficacy might have an association with extent of surgical resection.

Abstract
PURPOSE Pediatric primary high-grade spinal glioma (p-HGSG) is an extremely rare disease process, with little data within the current literature. Akin to primary high-grade gliomas, this cancer has been exemplified by dismal prognosis and poor response to modern treatment paradigms. This study seeks to investigate the current trends affecting overall survival using the National Cancer Database (NCDB). METHODS The NCDB was queried for p-HGSG between 2004 and 2016, by utilizing the designated diagnosis codes. Kaplan-Meier curves were generated, and log-rank testing was performed to analyze factors affecting overall survival. In addition, a Cox proportional-hazards model was used to perform multivariate regression analysis of survival outcomes. RESULTS A cohort of 97 patients was identified with a histologically confirmed p-HGSG. The overall incidence of p-HGSG in all pediatric spinal cord tumors is 7.5%, with a mean survival time of 25.3 months (SD, 21.0) and 5-year overall survival of 17.0%. The majority of patients underwent surgery (n = 87, 89.7%), radiotherapy (n = 73, 75.3%), and chemotherapy (n = 60, 61.9%). Univariate, multivariate, and Kaplan-Meier log-rank testing failed to demonstrate an association between performing surgery, extent of resection, radiotherapy, or chemotherapy with improved survival outcomes. CONCLUSIONS The current study constitutes the largest retrospective analysis of p-HGSGs to date, finding that current treatment options of surgery, radiotherapy, and chemotherapy have unclear benefit. This disease process has a poor prognosis without a current modality of treatment that conclusively alters survival. The risks and side effects of these treatment modalities must be carefully considered in such a highly aggressive disease process, especially given potentially limited survival benefits.

Abstract
PURPOSE Primary spinal cord glioblastoma (GBM) is a rare and devastating disease. Little attention was ever paid to this rare disease. As a result, the standard treatment protocol and prognostic factors of primary spinal cord GBM were not well established. The aim of this study was to determine the predictors associated with survival in patients with primary spinal cord GBM. METHODS A total of 122 patients with primary spinal cord GBM from Surveillance, Epidemiology, and End Results database and our institution were included in this retrospective analysis. Information about age, sex, race, tumor invasion, extent of resection, radiation, chemotherapy and year of diagnosis was collected. Univariate and multivariate accelerated failure time (AFT) regression model was performed to identify prognostic factors. RESULTS Of the 122 patients, 102 (83.6%) expired at the time of data collection. Overall survival at 1 year, 2 years, 3 years and 5 years was 48.4%, 22.8%, 17.1% and 8.4%, respectively, and median survival time was 12 months. Only radiation was found to be associated with survival in the AFT regression model (time ratio 1.94, 95% CI 1.01-3.72, p < 0.05). Radiotherapy could improve survival slightly; patients who received RT survived approximately two times as long as patients who did not receive RT, but the advantage was short term. CONCLUSION The survival of primary spinal cord GBM is poor in the current treatment strategy. Radiotherapy was associated with better survival, but the advantage was short term.

Abstract
Primary spinal cord glioblastoma multiforme (scGBM) is an uncommon entity in pediatrics, and intracranial metastasis originating in spinal cord gliomas is very rare. A 7-year-old female presented with weakness in the limbs, paralysis of the lower limbs and incontinence. The initial MRI of the spinal cord revealed expansion and abnormal signals from T2 to T5. She was initially diagnosed with Neuromyelitis optica spectrum disorders and treated with high-dose glucocorticoid and gamma globulin. Four months later, her symptoms worsened and follow-up imaging showed multiple intracranial mass lesions. We performed a subtotal resection of the right thalamic basal ganglia tumor and gross total resection of the right frontal lobe tumor under microscopic examination. Histopathology revealed scGBM with intracranial metastasis and the molecular pathology diagnosis suggested H3K27M mutant diffuse midline glioma WHO grade IV, which had previously been misdiagnosed as a Neuromyelitis optica spectrum disorders. We review the literature of intracranial metastases originating from pediatric primary spinal cord glioblastoma multiforme and summarize possible methods of differentiation, including changes in muscle strength or tone, intramedullary heterogeneously enhancing solitary mass lesions and cord expansion in MRI. Finally, we emphasize that in unexpected radiological changes or disadvantageous response to the treatment, a biopsy to achieve a pathological diagnosis is necessary to discard other diseases, especially neoplasms.

Abstract
Primary spinal cord tumors represent a hetereogeneous group of central nervous system malignancies whose management is complex given the relatively uncommon nature of the disease and variety of tumor subtypes, functional neurologic deficits from the tumor, and potential morbidities associated with definitive treatment. Advances in neuroimaging; integration of diagnostic, prognostic, and predictive molecular testing into tumor classification; and developments in neurosurgical techniques have refined the current role of radiotherapy in the multimodal management of patients with primary spinal cord tumors, and corroborated the need for prospective, multidisciplinary discussion and treatment decision making. Radiotherapeutic technological advances have dramatically improved the entire continuum from treatment planning to treatment delivery, and the development of stereotactic radiosurgery and proton radiotherapy provides new radiotherapy options for patients treated in the definitive, adjuvant, or salvage setting. The objective of this comprehensive review is to provide a contemporary overview of the management of primary intradural spinal cord tumors, with a focus on radiotherapy.

Abstract
The objective was to determine the impact of surgical resection and adjuvant therapies on survival in intramedullary ependymoma and astrocytoma. Secondary goals were to determine predictors of survival in surgical patients including histological grading, age and gender. Searching of Medline, Embase and Clinicaltrials.gov databases were performed. Multivariate analyses were performed for overall survival (OS) and progression-free survival (PFS) through Monte Carlo methods and Maximum Likelihood Estimation. 57 articles detail results for 3022 patients. Meta-analysis revealed the following factors to have a statistically significant effect on OS. Patients undergoing gross-total resection (GTR) are 5.37 times more likely to survive than patients with lesser volumes of tumor resected (HR for OS 1.68, p < 0.01). High-grade tumors were associated with a 14 times risk of death over low-grade tumors (HR for OS 2.64, p < 0.01). Radiation increased the risk of mortality in low-grade tumors (HR for OS 5.20, p < 0.01), but decreased mortality in high-grade lesions (HR for OS 2.46, p < 0.01). Adult patients were more likely to die from disease compared with pediatric patients by a factor of 1.6 (HR for OS 0.47, p < 0.01). In PFS, radiotherapy was associated with a reduced time to recurrence (HR for PFS 1.90, p < 0.01). There was a male predominance of 58%. Gender did not influence survival. 79% of patients demonstrated stable or improved functional neurological outcomes six months post-operatively. Our data indicates GTR improves OS in all tumor grades. Radiation improves OS only in the presence of high-grade histology. Advancing age and high-grade histology are negative prognostic indicators.

Magnetic Drug Targeting: A Novel Treatment for Intramedullary Spinal Cord Tumors. Sci Rep 2018; 8:11417.

Abstract
Most applications of nanotechnology in cancer have focused on systemic delivery of cytotoxic drugs. Systemic delivery relies on accumulation of nanoparticles in a target tissue through enhanced permeability of leaky vasculature and retention effect of poor lymphatic drainage to increase the therapeutic index. Systemic delivery is limited, however, by toxicity and difficulty crossing natural obstructions, like the blood spine barrier. Magnetic drug targeting (MDT) is a new technique to reach tumors of the central nervous system. Here, we describe a novel therapeutic approach for high-grade intramedullary spinal cord tumors using magnetic nanoparticles (MNP). Using biocompatible compounds to form a superparamagnetic carrier and magnetism as a physical stimulus, MNP-conjugated with doxorubicin were successfully localized to a xenografted tumor in a rat model. This study demonstrates proof-of-concept that MDT may provide a novel technique for effective, concentrated delivery of chemotherapeutic agents to intramedullary spinal cord tumors without the toxicity of systemic administration.

Abstract
STUDY DESIGN Retrospective cohort analysis of patients with spinal astrocytoma from multi-institutional data and the literature. OBJECTIVE To determine the prognostic factors, treatment, and survival of patients. SUMMARY OF BACKGROUND DATA Our current understanding of the epidemiology, prognosis, and optimal treatment of spinal astrocytoma is limited. The literature is confined to case reports or small institutional case series. METHOD Patient demographics, tumor characteristics, treatments, and outcomes were extracted. Univariate Kaplan-Meier survival analysis was performed to identify prognostic factors followed by multivariate Cox proportional hazard analysis. Wilcoxon signed-rank test was performed on pre- and postoperational functional status as measured by McCormick score. RESULTS Ninety-four patients from four institutions and 339 patients from the literature were included. For the multi-institutional cohort, WHO grade IV tumors had shorter progression-free survival (PFS) than those of lower grades, whereas gross total resection (GTR) (hazard ratio [HR]: 0.41, 95% confidence interval [CI]: 0.14-1.27, P = 0.124) trended toward longer PFS when compared to subtotal resection (STR). Age 18 years or older, paresthesia as a presenting symptom, and higher WHO grade were associated with shorter overall survival (OS), whereas thoracic tumor location when compared to cervical tumor location, biopsy when compared to STR, and radiotherapy (HR: 0.42, 95% CI: 0.20-0.88, P = 0.022) were associated with longer OS. For the literature cohort, GTR (HR 0.43, 95% CI: 0.24-0.77, P = 0.005) was associated with longer PFS when compared to STR, whereas higher WHO grade was associated with shorter PFS. Higher WHO grade and recurrence/progression were associated with shorter OS. Postoperative McCormick score was significantly higher than preoperative score (P < 0.001), but subgroup analysis of the change in McCormick score by extent of resection revealed no differences among groups (P = 0.551). CONCLUSION In patients with spinal astrocytomas, GTR likely resulted in longer PFS when compared to STR. Adjuvant radiotherapy appears to be effective in improving survival outcomes for high-grade tumors. LEVEL OF EVIDENCE 4.

Abstract
OBJECTIVE Intramedullary spinal cord tumors comprise 1%-10% of all childhood central nervous system neoplasms, with astrocytomas representing the most common subtype. Due to their rarity and poor prognosis, large population-based studies are needed to assess the epidemiology and survival risk factors associated with these tumors in the hope of improving outcome. The authors undertook this retrospective study to explore factors that may influence survival in pediatric patients with spinal cord astrocytomas. METHODS Utilizing the Surveillance, Epidemiology, and End Results (SEER) database, a prospective cancer registry, the authors retrospectively assessed survival in histologically confirmed, primary spinal cord astrocytomas in patients 21 years of age and younger. Survival was described with Kaplan-Meyer curves, and a multivariate regression analysis was used to assess the association of several variables with survival while controlling for confounding variables. RESULTS This analysis of 348 cases showed that age (hazard ratio [HR] 1.05, 95% CI 1.01-1.09, p = 0.017), nonwhite race (HR 1.74, 95% CI 1.11-2.74, p = 0.014), high-grade tumor status (HR 14.67, 95% CI 6.69-32.14, p < 0.001), distant or invasive extension of the tumor (HR 2.37, 95% CI 1.02-5.49, p = 0.046), and radiation therapy (HR 3.74, 95% CI 2.18-6.41, p < 0.001) were associated with decreased survival. Partial resection (HR 0.37, 95% CI 0.16-0.83, p = 0.017) and gross-total resection (HR 0.39, 95% CI 0.16-0.95, p = 0.039) were associated with improved survival. CONCLUSIONS Younger age appears to be protective, while high-grade tumors have a much worse prognosis. Early diagnosis and access to surgery appears necessary for improving outcomes, while radiation therapy has an unclear role. There is still much to learn about this disease in the hope of curing children with the misfortune of having one of these rare tumors.

Abstract
PURPOSE Primary spinal cord glioma is a rare entity especially in children; accounting for less than 10% of all central nervous system tumors. Low grade is the most reported subtype. Treatment modalities have largely evolved; large improvements have been made in the surgical field but also in both of radiotherapy and chemotherapy. Nevertheless, the optimal treatment is yet to be defined. MATERIAL AND METHODS A chart review of 11 pediatric patients with a diagnosis of low grade spinal cord glioma at Xhinhua hospital in Shanghai was conducted. A statistical package for Social Sciences Package (SPSS) was used for analysis. Means and standard deviations were calculated. The Kaplan-Meier method was used to analyze overall survival and progression-free survival. RESULTS The mean age was 6.7 years (range: 6 months-14.3 years). Revealing symptoms were variable and slowly progressive. The mean duration of symptoms prior to diagnosis was of 7±3.2 months. Astrocytoma was the most commonly reported histological type (seven cases, 63.6%), ependymomas were reported in three cases (27.3%). Surgery was performed in all patients. Subtotal resection concerned the majority of patients (nine patients, 81.8%). Adjuvant radiotherapy was indicated in all cases. A total dose of 39.6Gy was delivered to the whole group. Three patients received adjuvant chemotherapy, of whom two patients had grade III glioma and one patient had a tumor recurrence. Temozolomide-based regimen was the main protocol used for all our patients. The 3 years overall survival rate was 100%, whereas the progression free survival rate was 87.5%. One case relapsed during the next year following completion of treatment. CONCLUSION Our preliminary results are consistent with that of other similar published reports, however longer follow up is needed. So are specific recommendations that are still lacking in this setting.

Abstract
RATIONALE Primary spinal glioblastoma multiforme (GBM) is a rare clinical entity with an aggressive course and an invariably dismal prognosis. Its clinical characteristics, radiologic and pathologic findings, and treatment protocols have been discussed in a few cases. PATIENT CONCERNS A 15-year-old female was admitted to the neurology department with a chief complaint of progressive numbness and weakness in her left upper extremity for 3 months and neck pain for 1 month. DIAGNOSES Spinal magnetic resonance imaging showed an intramedullary expansile mass localized between C4 and C7. The diagnosis of GBM was determined on the basis of the histopathological findings after operation. INTERVENTIONS Laminotomy and laminoplasty between C4 and C7 were performed, and the tumor was partially resected. The patient was administered focal adjuvant radiotherapy concomitantly with oral chemotherapy following the surgery. OUTCOMES With severe neurologic deficits at 13 months after the diagnosis, the patient expired. LESSONS Although therapeutic options have been improving, the prognosis of the primary spinal GBM remains poor. The treatment of primary spinal GBM entered into a central registry and multiple-center cooperation is important in establishing future therapeutic strategies.

Abstract
OBJECTIVE The incidence of primary spinal cord glioblastoma multiforme (GBM) in the pediatric age group is very rare. Only a few case series and case reports have been published in the literature; therefore, overall survival (OS) outcome and the as-yet poorly defined management options are not discussed in detail. The authors performed a cumulative survival analysis of all reported cases of pediatric spinal cord GBM to identify the predictive factors related to final survival outcome. METHODS A comprehensive search for relevant articles was performed on PubMed's electronic database MEDLINE for the period from 1950 to 2015 using the search words "malignant spinal cord tumor" and "spinal glioblastoma multiforme." This study was limited to patients younger than 18 years of age. Survival rates for children with various tumor locations and treatments were collected from the published articles and analyzed. RESULTS After an extensive literature search, 29 articles met the study inclusion criteria. From the detailed information in these articles, the authors found 53 children eligible for the survival analysis. The majority (45%) of the children were more than 12 years old. Thirty-four percent of the cases were between 7 and 12 years of age, and 21% were younger than 7 years. In the Kaplan-Meier survival analysis, children younger than 7 years of age had better survival (13 months) than the children older than 7 years (7-12 years: 10 months, > 12 years: 9 months; p = 0.01, log-rank test). Fifty-five percent of the children were female and 45% were male. A cervical tumor location (32%) was the most common, followed by thoracic (28.3%). Cervicothoracic (18.9%) and conus (18.8%) tumor locations shared the same percentage of cases. Cervical tumors had a worse outcome than tumors in other locations (p = 0.003, log-rank test). The most common presenting symptom was limb weakness (53%), followed by sensory disturbances (25%). Median OS was 10 months. The addition of adjuvant therapy (radiotherapy [RT] and/or chemotherapy [CT]) after surgery significantly improved OS (p = 0.01, log-rank test). Children who underwent gross-total resection and RT had better outcomes than those who underwent subtotal resection and RT (p = 0.04, log-rank test). Cerebrospinal fluid spread, hydrocephalus, brain metastasis, and spinal metastasis were not correlated with OS in primary spinal GBM. CONCLUSIONS Adjuvant therapy after surgery had a beneficial effect on overall outcome of spinal GBM in the pediatric age group. Gross-total resection followed by RT produced a better outcome than subtotal resection with RT. Further large-scale prospective study is required to establish the genetic and molecular factors related to OS in primary GBM of the spinal cord in pediatric patients.

Abstract
Pediatric spinal cord glioblastoma multiforme is a rare entity with a poor prognosis often presenting with lower extremity weakness or paralysis. Previous literature suggests that aggressive surgical resection may provide overall survival benefit; however, there is limited concurrent analysis demonstrating neurological recovery following surgical resection. We report the case of a 9-year-old boy who presented with complete paraplegia and regained the ability to ambulate independently following subtotal surgical resection, radiation, and chemotherapy. The case demonstrates the balance between meaningful neurological recovery and overall survival when deciding on the extent of resection in cases of pediatric spinal glioblastoma multiforme.

Abstract
Intramedullary spinal cord tumors have low incidence rates but are associated with difficult treatment options. The majority of patients with these tumors can be initially treated with an attempted resection. Unfortunately, those patients who cannot undergo gross-total resection or have subtotal resection are left with few treatment options, such as radiotherapy and chemotherapy. These adjuvant treatments, however, are associated with the potential for significant adverse side effects and still leave patients with a poor prognosis. To successfully manage these patients and improve both their quality of life and prognosis, novel treatment options must be developed to supplement subtotal resection. New research is underway investigating alternative therapeutic approaches for these patients, including directed, localized drug delivery and nanomedicine techniques. These and other future investigations will hopefully lead to promising new therapies for these devastating diseases.

Abstract
OBJECT The impact of central pathology review on outcome has been described in pediatric patients with high-grade glioma (HGG). The objective of this report was to analyze the impact of the central pathology review on outcome in the subgroup of patients with institutional diagnosis of HGG of the spinal cord enrolled in the Children's Cancer Group 945 cooperative study. METHODS Five neuropathologists centrally reviewed the pathology of the 18 patients with HGG of the spinal cord who were enrolled in the study. These reviews were independent, and reviewers were blinded to clinical history and outcomes. A consensus diagnosis was established for each patient, based on the outcome of the review. RESULTS Of 18 patients, only 10 were confirmed to have HGG on central review. At a median follow-up of 12 years, event-free and overall survival for all 18 patients was 43.2% ± 13.3% and 50% ± 13.4%, respectively. After central review, 10-year event-free and overall survival for confirmed HGGs and discordant diagnoses was 30% ± 12.5% versus 58.3% ± 18.8% (p = 0.108) and 30% ± 12.5% versus 75% ± 14.2% (p = 0.0757), respectively. CONCLUSIONS The level of discordant diagnoses in children and adolescents with institutional diagnosis of HGG of the spinal cord was 44% in this experience. However, there was no significant difference in outcome between patients with confirmed and discordant diagnosis. This group of tumor deserves a specific attention in future trials.

Abstract
Our aim was to determine the characteristics, treatments and outcomes of patients with primary spinal glioblastomas (GB) or gliosarcomas (GS) reported in literature until March 2015. PubMed and Web of Science were searched for peer-reviewed articles pertaining to cases of glioblastomas / gliosarcomas with primary spinal origin, using predefined search terms. Furthermore we performed hand searches tracking the references from the selected papers. Eighty-two articles published between 1938 and March 2015 were eligible. They reported on 157 patients. Median age at diagnosis was 22 years. The proportion of patients who received adjuvant chemo- or radiotherapy clearly increased from the time before 1980 until present. Median overall survival from diagnosis was 8.0 ± 0.9 months. On univariate analysis age influenced overall survival, whereas tumor location, gender and the extent of initial resection did not. Outcomes did not differ between children (< 18 years) and adults. However, the patients who were treated after 1980 achieved longer survival times than the patients treated before. On multivariable analysis only age (< 60 years) and the time period of treatment (≥ 1980) were confirmed as positive independent prognostic factors. In conclusion, primary spinal GB / GS mainly affect younger patients and are associated with a dismal prognosis. However, most likely due to the increasing use of adjuvant treatment, modest therapeutic progress has been achieved over recent decades. The characteristics and treatments of primary spinal glioblastomas should be entered into a central registry in order to gain more information about the ideal treatment approach in the future.

Abstract
Background: Pediatric intramedullary spinal cord lesions are not only rare but also different from adults in a number of aspects. We aimed to study the incidence and the frequencies of various pediatric intramedullary mass lesions, their outcome to treatment and the factors determining their outcome of treatment. Materials and Methods: Thirty-one consecutive children (aged 1–18 years, mean 11.1 years, male: female = 1.8:1) with pathologically proven intramedullary spinal cord lesions treated at our center were studied. Clinico-radiological, histopathological, operative, and outcome data were reviewed retrospectively. The functional status was assessed using the modified McCormick grading system. Results: Gross total tumor excision was performed in 19 patients (61.3%), subtotal in 9 patients (29%), partial excision was performed in 2 (6.5%) patient, and only biopsy was performed in 1 patient (6.5%). There was one peroperative death, 2 patients died at follow-up. Complications included wound related complications (n = 4), transient deterioration in the motor power, and respiratory complication requiring a tracheostomy. Six patients showed recurrence at a mean follow-up of 16.4 months. Developmental tumors, high-grade ependymomas, and incompletely excised grade 2 ependymomas showed a tendency to recur. Conclusions: Children constituted nearly 1/5th (17.4%) of intramedullary spinal cord tumors. Astrocytomas and ependymomas taken together constituted the most common intramedullary spinal lesions in children; however, developmental tumors predominated in the first decade. Children usually presented in good functional grades preoperatively and maintained good grades after surgery. Functional outcome was dependent on the preoperative neurological status and histopathology of the lesions.

Abstract
AIM To evaluate clinical and radiological findings, pathological features and treatment modalities in pediatric patients with intramedullary spinal cord tumors. PATIENTS AND METHODS The medical records of 36 patients with intramedullary spinal tumors were reviewed for clinical, radiological and histopathological data, chemotherapy, radiotherapy, surgical resection, treatment responses, events, and final outcome. Survival analyses were performed. RESULTS The median age was 7.9 years (range: 1-16 years; male/female ratio:1.4). Majority of the tumors were histopathologically diagnosed as astrocytomas (n = 16, 44.4%) and ependymomas (n = 19, 52.8%); whereas one was unclassified glioma. Overall, 94% of the astrocytomas and 84% of the ependymomas were low-grade, only three tumors were high-grade. In one patient with ependymoma, histopathological grade was undetermined. The primary tumor was commonly located in thoracic (47%) and cervical segments (28%). All patients had undergone surgery (gross-total resection, 33%; subtotal resection, 45%; biopsy, 22%). Radiotherapy was administered to 26 patients (72%) and chemotherapy to 15 patients (42%). The 3-, 5- and 10-year overall survival rates were 72%, 63% and 56%, respectively; and event-free survival rates were 43%, 40% and 40%. Survival did not significantly differ with gender, age groups, lag-time, neurologic status, histopathological tumor type, tumor location, extent of resection, treatment, or treatment responses in univariate survival analyses. Survival rates were significantly higher in patients with low-grade tumors and in ependymoma patients with resected tumors. CONCLUSIONS Patients with low-grade tumors and those who underwent gross-total tumor resection had better prognosis. Surgery remains the main treatment in intramedullary spinal tumors. The role of radiotherapy and chemotherapy is limited and even controversial in low-grade tumors.

Abstract
Background Several uncertainties remain concerning the management of intramedullary spinal cord tumours (IMSCTs). These include the timing and extent of resection, its interrelated functional outcome, and the adequate use and timing of radiation therapy and/or chemotherapy. In this retrospective study we report on all adult cases involving IMSCTs treated from 1987 to 2007 in our institution to validate our treatment strategy for IMSCTs. Pre- and post-operative functional performance was classified according to the McCormick scale. Results A total of 70 adult cases with IMSCTs consisting of ependymoma (39), astrocytoma (11), carcinoma metastasis (8), haemangioblastoma (5), cavernoma (3) and others (4) were reviewed. Mean age was 46.8 years (range, 18-79 years), and mean follow-up was 4.5 years (range, 1-195 months). The proportion of localisation in descending order was thoracic (36%), cervical (33%), cervicothoracic (19%) and conus region (13%), with 45 gross total resections, 22 partial resections and three biopsies. Surgery-related morbidity with worsening postoperative symptoms occurred immediately in 13 patients (18.6%). The preoperative McCormick grade correlated significantly with the early postoperative grade and the grade at follow-up (χ2-test; p = 0.001). None of the patients with preserved intraoperative evoked potentials exhibited significant postoperative deterioration. The degree of resection was correlated with progression-free survival (Duncan test; p = 0.05). Most patients with malignant tumours, namely anaplastic ependymoma (3), astrocytoma (2) or metastatic lesions (5), underwent postoperative radiation therapy. Six patients (one anaplastic ependymoma, two anaplastic astrocytomas and three metastatic lesions) received postoperative chemotherapy. Conclusions IMSCTs should be operated on when symptoms are mild. We recommend evoked potential-guided microsurgical total resection of ependymomas and other benign lesions; partial resection or biopsy followed by adjuvant therapy should be confined to patients with high-grade astrocytomas, whereas resection or biopsy with adjuvant therapy is the best option for metastatic lesions.

Abstract
INTRODUCTION Although uncommon, there is significant morbidity and mortality associated with paediatric spinal glioblastoma. The paucity of cases makes treatment options difficult. The current recommended standard of care is biopsy followed by adjuvant chemo-radiotherapy, with emerging data supporting the role of safe gross total resection. OBJECTIVE The purpose of this paper is to provide a single-institution case study and to discuss current and future therapeutic treatment strategies. CASE PRESENTATION A 14-year-old boy presented with a 2-year history of intermittent back pain with recent progressively worsening motor and sensory deficits of the right side. Pre-operative MRI revealed an enhancing intra-medullary tumour extending from C2 to C7. During the operative case, no tumour-cord margin could be identified, and the patient underwent a subtotal excision. Histopathology confirmed glioblastoma. In the subsequent weeks, the patient's clinical condition deteriorated. Adjuvant therapy was declined by the family, and the patient died 9 weeks after initial presentation. CONCLUSION Despite major advances in surgical techniques, peri-operative neuro-imaging as well as chemo-radiotherapy, the prognosis of a paediatric intra-medullary high-grade spinal tumour remains poor. Detailed analysis of our understanding of tumour dynamics in this patient group is important in establishing future therapeutic strategies.

Abstract
STUDY DESIGN Observational cross-sectional study. OBJECTIVE Using data from the population-based cancer registries of the Surveillance, Epidemiology and End Results (SEER) program, we analyzed demographic features, tumor and treatment characteristics, as well as survival rates in patients with primary malignant astrocytomas of the spinal cord (PMASC). SUMMARY OF BACKGROUND DATA PMASC is a rare neoplasm and is considered to carry the same dismal outcome as their cerebral counterparts. Our current knowledge is incomplete, and understanding the epidemiology, diagnosis, and optimal treatment still poses challenges. METHODS The SEER data from 1973 to 2007 were reviewed for pathologically confirmed primary anaplastic astrocytomas (AA) and glioblastomas of the spinal cord (C72.0). We compared the clinical features and outcomes of the cohort in uni- and multivariate fashion. Survival was calculated and compared using Kaplan-Meier curves and log-rank analysis. RESULTS Our search criteria retrieved 135 patients diagnosed with PMASC. The median survival for PMASC was 13 months with 1-, 2-, and 5-year survival rates of 51.8%, 32.2%, and 18.7%. Patient diagnosed with AA had a median survival time of 17 months versus 10 months in patients diagnosed with glioblastomas. Adult patients observed markedly prolonged survival compared with the pediatric group, with a 16-month versus 9-month median survival, respectively. Multivariate analysis revealed age at diagnosis, pediatric and adult age groups, sex, tumor histology, and extent of resection as significant predictors of survival. Interestingly, outcomes did not significantly change throughout the last decades or by receiving radiotherapy. CONCLUSION Outcome for patients diagnosed with PMASC remains poor and presents an ongoing challenge for professionals in the field of neurospinal medicine and surgery. In our analyses of AA, adult patients, males, and patients undergoing radical resections were associated with increased survival. However, incidence of these lesions is low; hence, building strong collaborative, interdisciplinary, and multi-institutional study groups is necessary to define the optimal treatment of PMASC.

Abstract
PURPOSE High-grade gliomas of the CNS are characterized by poor treatment response and prognosis for long-term survival. The Children's Oncology Group (COG) L991 study investigated the neuropsychological, behavioral, and quality of life (QoL) outcomes after treatment on the Children's Cancer Group (CCG) trial for high-grade gliomas (CCG-945). PATIENTS AND METHODS Fifty-four patients (29 males, 25 females) with a median age of 8.8 years at diagnosis (range, 0.2 to 19.5 years) were enrolled at 25 institutions in North America, representing 81% of available survivors; median length of follow-up was 15.1 years (range, 9.5 to 19.2 years), and median age at study evaluation was 23.6 years (range, 11.3 to 36 years). Standardized tests of neuropsychological functioning and QoL were performed. Descriptive statistics summarized principal findings, and one-way analysis of variance identified potential predictors of outcomes. RESULTS With an average follow-up time of 15 years, survivors demonstrated intellectual functioning within the low-average range. Executive functioning and verbal memory were between the low-average and borderline ranges. In contrast, visual memory and psychomotor processing speed were between the borderline and impaired ranges, respectively. Approximately 75% of patient reported overall QoL within or above normal limits for both physical and psychosocial domains. Nonhemispheric tumor location (midline or cerebellum), female sex, and younger age at treatment emerged as independent risk factors. CONCLUSION These results serve as a benchmark for comparison with future pediatric high-grade glioma studies, in addition to identifying at-risk cohorts that warrant further research and proactive interventions to minimize late effects while striving to ensure survival.

Spinal glioblastoma multiforme of the conus medullaris with holocordal and intracranial spread in a child: a case report and review of the literature. Spine J 2012; 12:e1-6. [PMID: 22197783 DOI: 10.1016/j.spinee.2011.12.005] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2010] [Revised: 08/01/2011] [Accepted: 12/01/2011] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Spinal glioblastoma multiforme (GBM) is a rare clinical entity. According to our review of the literature, only 15 cases of spinal GBM originating from the conus medullaris (CM) have been reported. Furthermore, there has been no case of spinal GBM originating from the CM with holocordal and intracranial involvements, which were already present at the time of initial diagnosis. Despite a variety of treatments, the previous studies have uniformly reported poor results of this lethal condition. PURPOSE The present report illustrates a 10-year-old girl with spinal GBM with rare involvement pattern, that is, the tumor originating from the CM with the holocordal and intracranial involvements, undergoing a novel chemotherapy regimen. STUDY DESIGN A case report and review of literature. METHODS Magnetic resonance (MR) imaging with gadolinium enhancement clearly revealed holocordal and intracranial lesions, which were otherwise unidentifiable by plane MR imaging. Open biopsy was performed. After histologic diagnosis, novel chemotherapy regimen, that is, simultaneous high-dose chemotherapy (cyclophosphamide, cisplatin, vincristine, and etoposide) combined with autologous peripheral blood stem cell transplantation (auto-PBSCT), intrathecal injections of both methotrexate and dexamethasone, and radiotherapy, which respected the tolerance threshold of the spinal cord, were performed. RESULTS Novel chemotherapy regimen achieved marked tumor regression until the 12th month of treatment. The patient became ambulatory with T-shaped canes and has returned to the school life. Unfortunately, the patient died because of the relapse of the tumor 14 months after the initial diagnosis; however, this strategy has achieved longer survival than previously reported mean survival (12 months). CONCLUSIONS The authors advocate enhanced MR imaging of the whole central nervous system for the potential spreading of this disease. This is the first report of simultaneous high-dose chemotherapy combined with auto-PBSCT, intrathecal injections of antineoplastic agents, and radiotherapy for the treatment of spinal GBM, which achieved marked tumor regression. We believe that accumulated experiences in the treatment of this lethal condition might contribute well to improve its therapeutic outcome.

Abstract
BACKGROUND/AIMS Primary pediatric high-grade spinal cord astrocytomas are rare neoplasms with poor prognoses. Using the Surveillance, Epidemiology, and End Results (SEER) database, we analyzed prognostic factors and survival. METHODS Pediatric patients with histologically confirmed diagnoses of primary high-grade spinal cord astrocytoma (WHO grade III-IV) from 1973 to 2008 in the SEER database were studied. Univariate and multivariate Cox proportional hazards models were used to analyze the relationship between demographic, tumor grade, and treatment factors on survival. RESULTS Median survival in the 48 patient cohort was 10 months. Increasing age and higher tumor grade were found to be significantly associated with higher mortality. For children aged <7, 7-12, and 13-18 years, median survival was 22, 11, and 8 months, respectively. For children with anaplastic astrocytoma (WHO grade III), median survival was 12 months, compared with 7 months for those with glioblastoma multiforme (WHO grade IV). This study did not find a statistically significant relationship between sex, race, presence of radiation therapy or extent of surgical resection and mortality. CONCLUSION Survival in primary pediatric high-grade spinal cord astrocytomas was positively associated with younger age and lower tumor grade. Survival was not associated with other demographic or treatment modality factors.

Abstract
Intramedullary tumors of the spinal cord account for 35-40% of intraspinal tumors in children. The biological behavior of these tumors is of slow progression, and hence aggressive surgery has been advocated. Surgical adjuncts include use of intraoperative neurophysiological monitoring, preoperative ultrasound, microsurgical techniques and ultrasonic suction devices. Osteoplastic laminoplasty approaches avoid post-laminectomy deformities in younger children. Postoperative radiotherapy and more recently chemotherapy regimes have been proposed for incompletely resected tumors.

Abstract
Little is known about pediatric spinal cord high grade gliomas (SCHGG) beyond their dismal prognosis. Here, we analyzed the HIT-GBM(®) database for the influence of surgical resection on survival. Between 1991 and 2010 the HIT-GBM group collected data from European children diagnosed with high grade glioma. Patients with the following inclusion criteria were analyzed in this study: astrocytic histology, WHO grade III or IV, age at diagnosis <18 years, and tumor localized to the spinal cord. 28 patients (mean age 11.28 years, 14 male) with primary SCHGG were identified. The tumor sizes were measured by the span across adjacent vertebrae and varied greatly (range: 1-20, median: 4). Histology was classified as WHO grade III in 15 and grade IV in 13 tumors. Of note, the four largest tumors identified were WHO grade III. Surgery was classified as complete resection (n = 6), subtotal resection (STR) (n = 7), partial resection (n = 12) or biopsy only (n = 3). 27 patients received chemotherapy, 22 of which also received radiation. With the mean follow-up time of 2.88 (SD ± 2.95) years, 14 patients were still alive resulting in a median overall survival of 2.5 years (SE ± 1.6). The positive prognostic indicators for overall survival were: age younger than 5 years (P = 0.047), WHO grade III (P = 0.046), absence of necrosis (P = 0.025) and gross total resection (GTR) (P = 0.012). The prognosis of SCHGG might not be as miserable as generally assumed. GTR is of benefit. Larger data sets and meta-analysis are necessary to identify patient sub-groups.

Abstract
BACKGROUND Tumors of the spinal cord are exceedingly rare in infancy and only a paucity of literature exists describing the spectrum of this disease and its management. The objectives of our study were to describe the demographic characteristics of spinal cord tumors (SCT) in children less than 3 years of age at diagnosis and to review their treatment and outcome. METHODS A national retrospective chart review was conducted on patients under the age of 3 years diagnosed with a primary tumor of the central nervous system (CNS) between 1990 and 2005 across Canada. Inclusion criteria were: age ≤ 3 years, histologic confirmation of the diagnosis, and residency in Canada. A centralized database was created and information regarding SCT was extracted. RESULTS Twenty-five of five hundred seventy-nine patients (4.3%) in the data bank had a SCT. The majority of tumors were low-grade astrocytomas (14/25). Leptomeningeal dissemination based on neuroradiologic imaging and/or cerebrospinal fluid cytology was present in five (20%) patients. The majority of patients underwent an incomplete surgical resection (52%). Most patients (64%) did not receive postoperative radiotherapy or chemotherapy. Seventy-two percent (18/25) developed recurrent/progression of disease. Overall 2- and 5-year survival for low- and high-grade malignancies was 93 ± 6.4% and 37.5 ± 17.1% respectively. Significant predictors of survival included mean duration of symptoms prior to initial diagnosis and recurrence/progression of disease. CONCLUSIONS Relapse/progression of disease in infant SCT is frequent. Prolonged survival of low-grade tumors is possible with further therapy; however, the prognosis of high-grade malignancies remains poor.

Abstract
OBJECTIVE Late neurologic deterioration after brachial plexus injury (BPI) is uncommon and may be caused by multiple etiologies. An unusual, previously unreported, case of late neurologic deterioration after BPI is presented. METHODS A pediatric patient previously treated for a traumatic preganglionic BPI and presenting with neurologic deterioration 5 years after his injury is reviewed. RESULTS Magnetic resonance imaging and computed tomography myelogram revealed spinal cord herniation at the same level of the previous nerve root avulsions. Surgical open biopsy demonstrated a spinal cord anaplastic astrocytoma. Despite craniospinal radiotherapy and different regimens of chemotherapy, he died 4 years later from leptomeningeal spread. CONCLUSION This case illustrates a previously unreported cause of late neurologic deterioration following BPI. The probable coincidental versus possible causal interrelationship of these two processes (BPI and spinal cord tumor) is discussed, but no conclusions can be reached.

Abstract
Spinal cord tumors in pediatric patients are rare, representing less than 1% of all central nervous system tumors. Two cases of pediatric primary intramedullary spinal cord glioblastoma at ages 14 and 8 years are reported. Both patients presented with rapid onset paraparesis and quadraparesis. Magnetic resonance imaging in both showed heterogeneously enhancing solitary mass lesions localized to lower cervical and upper thoracic spinal cord parenchyma. Histopathologic diagnosis was glioblastoma. Case #1 had a small cell component (primitive neuroectodermal tumor-like areas), higher Ki67, and p53 labeling indices, and a relatively stable karyotype with only minimal single copy losses involving regions: Chr8;pter-30480019, Chr16;pter-29754532, Chr16;56160245–88668979, and Chr19;32848902-qter on retrospective comparative genomic hybridization using formalin-fixed, paraffin-embedded samples. Case #2 had relatively bland histomorphology and negligible p53 immunoreactivity. Both underwent multimodal therapy including gross total resection, postoperative radiation and chemotherapy. However, there was no significant improvement in neurological deficits, and overall survival in both cases was 14 months.This report highlights the broad histological spectrum and poor overall survival despite multi modality therapy. The finding of relatively unique genotypic abnormalities resembling pediatric embryonal tumors in one case may highlight the value of genome-wide profiling in development of effective therapy. The differences in management with intracranial and low-grade spinal cord gliomas and current management issues are discussed.

Abstract
OBJECT Patients having a primary tumor of the spinal cord, spinal meninges or cauda equina, are relatively rare. Neurosurgeons encounter and treat such patients, and need to be aware of their clinical presentation, tumor types, treatment options, and potential complications. The purpose of this paper is to report results from a series of 430 patients with primary intraspinal tumors, taken from a larger cohort of 9661 patients with primary tumors of the CNS. METHODS Extensive information on individuals diagnosed (in the year 2000) as having a primary CNS neoplasm was prospectively collected in a Patient Care Evaluation Study conducted by the Commission on Cancer of the American College of Surgeons. Data from US hospital cancer registries were submitted directly to the National Cancer Database. Intraspinal tumor cases were identified based on ICD-O-2 topography codes C70.1, C72.0, and C72.1. Analyses were performed using SPSS. RESULTS Patients with primary intraspinal tumors represented 4.5% of the CNS tumor group, and had a mean age of 49.3 years. Pain was the most common presenting symptom, while the most common tumor types were meningioma (24.4%), ependymoma (23.7%), and schwannoma (21.2%). Resection, surgical biopsy, or both were performed in 89.3% of cases. Complications were low, but included neurological worsening (2.2%) and infection (1.6%). Radiation therapy and chemotherapy were administered to 20.3% and 5.6% of patients, respectively. CONCLUSIONS Data from this study are suitable for benchmarking, describing prevailing patterns of care, and generating additional hypotheses for future studies.

Abstract
Primary spinal cord tumors constitute 2-4% of all primary central nervous system malignancies in adults of which less than 5% are glioblastoma. A retrospective evaluation to determine toxicity and response to bevacizumab in patients with recurrent spinal cord glioblastoma. Six patients (4 males; 2 females: median age 34 years) with recurrent spinal cord glioblastoma were treated with bevacizumab (10 mg/kg given once every 2 weeks wherein 2 treatments constituted a cycle of therapy). All patients had failed surgery and temozolomide-based chemoradiotherapy and post-radiotherapy temozolomide. Blood counts, chemistry panel, urine protein to creatinine ratio and neurologic examination were obtained bi-weekly. Contrast-enhanced spine MRI was performed after one cycle of therapy and thereafter following every two cycles of bevacizumab. Treatment-related complications included fatigue in six patients, constipation in 4, hypertension in 2, venous thrombosis in 2, and infection without neutropenia in 2. There were three grade 3 toxicities (1 each fatigue, leukopenia and venous thrombosis). There were no treatment-related deaths. After one cycle of bevacizumab, one patient (17%) demonstrated progressive disease, 2 (34%) partial responses and three (51%) stable disease. Overall median response or stable disease duration (disease free progression) was 7 months (range 3-11 months). Overall median survival was 9 months (range of 5-13 months). Bevacizumab is well tolerated, has tolerable toxicity and apparent activity in this small cohort of adults with recurrent spinal cord glioblastoma.

Abstract
Spinal glioblastoma multiforme (GBM) is rare in children. New therapeutic options should be explored given the poor outcomes reported. We describe the case of an infant with spinal GBM whose condition worsened despite radiotherapy and chemotherapy. Immunohistochemical analysis of the tumor sample showed activation of the Raf-MEK-ERK pathway. Targeted pharmacologic therapy with sorafenib plus valproic acid led to decrease in the size of the tumor and improvement of symptoms. We conclude that regulation of the mitogen-activated protein kinase pathway using sorafenib plus valproic acid warrants further investigation for the management of childhood GBM.

Abstract
PURPOSE To report the outcome using radiation therapy (RT) for pediatric patients with high-grade spinal cord tumors. METHODS AND MATERIALS A retrospective chart review was conducted that included 17 children with high-grade spinal cord tumors treated with RT at St. Jude Children's Research Hospital between 1981 and 2007. Three patients had gross total resection, 11 had subtotal resection, and 3 underwent biopsy. The tumor diagnosis was glioblastoma multiforme (n = 7), anaplastic astrocytoma (n = 8), or anaplastic oligodendroglioma (n = 2). Seven patients received craniospinal irradiation (34.2-48.6 Gy). The median dose to the primary site was 52.2 Gy (range, 38-66 Gy). RESULTS The median progression-free and overall survivals were 10.8 and 13.8 months, respectively. Local tumor progression at 12 months (79% vs. 30%, p = 0.02) and median survival (13.1 vs. 27.2 months, p = 0.09) were worse for patients with glioblastoma multiforme compared with anaplastic astrocytoma or oligodendroglioma. The median overall survival was shorter for patients when failure included neuraxis dissemination (n = 8) compared with local failure alone (n = 5), 9.6 vs. 13.8 months, p = 0.08. Three long-term survivors with World Health Organization Grade III tumors were alive with follow-up, ranging from 88-239 months. CONCLUSIONS High-grade spinal cord primary tumors in children have a poor prognosis. The propensity for neuraxis metastases as a component of progression after RT suggests the need for more aggressive therapy.

Abstract
Primary spinal cord tumors represent 2-4% of all neoplasms of the CNS. Primary spinal cord tumors are anatomically separable into two broad categories: intradural intramedullary and intradural extramedullary. Intramedullary tumors are comprised predominantly of gliomas (infiltrative astrocytomas and ependymomas). Resective surgery can usually be accomplished with spinal ependymomas owing to separation of tumor from spinal cord and, when complete, require no further therapy. By contrast, spinal cord gliomas infiltrate the myelon and, consequently, surgery is nearly always incomplete. Involved-field radiotherapy is most often administered after partial resection. Intradural extramedullary tumors are either peripheral nerve sheath tumors (neurofibromas or schwanommas) or meningiomas. In either instance, complete resection may be accomplished and is often curative. Radiotherapy is reserved for rare malignant variants and for patients in whom surgery is contraindicated. Chemotherapy is administered for recurrent primary spinal cord tumors without other options, that is, reoperation or re-irradiation. Problematic, however, is the lack of clinical trials in general for these CNS tumors and for spinal cord tumors in particular. Consequently, treatment is similar to that for intracranial tumors with a similar histology. Early recognition of the signs and symptoms of primary spinal cord tumors allows for early treatment, potentially minimizes neurologic morbidity and improves outcome. Primary treatment is surgery in essentially all spinal cord tumors, and predictors of outcome include preoperative functional status, histological grade of tumor and extent of surgical resection.

Abstract
STUDY DESIGN Clinically based systematic review. OBJECTIVE To define optimal clinical care for primary intramedullary spinal cord tumors using a systematic review with expert opinion. METHODS Focused questions on the treatment of primary intramedullary spinal cord tumors were refined by a panel of spine oncology surgeons, medical and radiation oncologist. Keyword were searched through Medline database and pertinent abstracts and manuscripts obtained. The quality of literature was rated as high, moderate, low, or very low. Using the GRADE evidence based review system the proposed questions were answered using the literature review and expert opinion. These treatment recommendations were then rated as either strong or weak based on the quality of evidence and clinical expertise. RESULTS The literature searches revealed low and very low quality evidence with no prospective or randomized studies. The MEDLINE search engine returned 9000 articles which was restricted to articles about human subjects and written in the English language. The subsequent search resulted in a return of: "spinal cord tumor" (5053), "ependymoma" (580), "astrocytoma" (420), and "glioma" (235) articles. Seventeen articles referenced timing of surgical intervention and symptomatology for intramedullary spinal cord tumors. One hundred fifty-eight chemotherapy and 183 radiation therapy articles for intramedullary spinal cord tumors were reviewed. CONCLUSION The most important factor in determining the IMSCT patient's long-term neurologic and functional outcome after surgery is the patient's preoperative neurologic status. However, this must be taken in the context of the underlying tumor histology. Therefore, resection is reserved for progressive neurologic decline and serial monitoring for asymptomatic individuals. Adjuvant therapy is an option for high grade astrocytomas (WHO grades 3-4).

Abstract
Astrocytomas affect a significant portion of patients with intramedullary tumors. These infiltratively growing tumors are treated by a variety of methods -- biopsy and decompressive surgery, maximal safe resection, adjuvant oncological therapy. Also, numerous prognostic factors are reported in the literature. Better understanding of factors that influence prognosis may help in treatment planning with the goal of prolonging survival. We have thus undertaken an extensive literature review in order to define factors affecting prognosis. A total of 38 articles were studied. Only tumor grade was consistently reported as the major factor affecting prognosis. The influence of other clinical factors (age, gender, history length, functional status, tumor location or extent, syrinx or cyst presence) can be speculated upon, but cannot be assessed adequately from the available literature. For both low- and high-grade (HG) astrocytomas, maximal safe tumor resection should be the primary treatment objective but is often not feasible in contrast to other intramedullary and spinal neoplasms. Since the biological nature of spinal cord HG glioma is identical to that of the brain, the same treatment algorithm of maximal safe resection followed by concomitant radio- and chemotherapy would be sensible to implement.

Abstract
Pediatric intramedullary spinal cord tumors are rare and account for 3% to 6% of all central nervous system tumors. Astrocytomas are infiltrating neoplasms, and they predominate in the pediatric population. We report a case of an intramedullary spinal cord astrocytoma in a 5-year-old boy with nonspecific mid-back pain for 3 months. Physical examination revealed clonus, thoracolumbar tenderness, and pain with sitting straight leg raises. An urgent magnetic resonance imaging showed an intramedullary tumor in the mid-thoracic cord, confirmed by surgical excision. The physician should maintain a high index of suspicion when evaluating the pediatric patient who presents with unexplained and persistent back pain. Associated findings, including nocturnal pain and neurological symptoms may indicate a more serious underlying pathology such as a tumor. Early detection, prompt treatment, and proper post surgical management will often lead to improved outcomes in patients.

Abstract
Although significant advances have been made in treating malignant pediatric central nervous system tumors such as medulloblastoma, no effective therapy exists for diffuse pontine glioma or intramedullary spinal astrocytoma. Biology of these 2 tumors is poorly understood, in part because diffuse pontine gliomas are not treated surgically, and tumor specimens from intramedullary spinal astrocytomas are rare and minuscule. At the 2007 Neurobiology of Disease in Children Symposium, we presented evidence that malignant glioma behaviors, including antiapoptosis, invasiveness, and treatment resistance, are enhanced by hyaluronan, an extracellular glycosaminoglycan. We review the clinical course of pediatric intramedullary spinal astrocytoma and diffuse pontine glioma, and show expression of membrane proteins that interact with hyaluronan: CD44, extracellular matrix metalloproteinase inducer, and breast cancer resistance protein (BCRP/ABCG2). Furthermore, we describe novel animal models of these tumors for preclinical studies. These findings suggest that hyaluronan antagonism has potential therapeutic value in malignant central nervous system tumors.
