Abstract
Ganglioneuromas (GNs) are rare benign tumors common in the pediatric population. Although mostly asymptomatic, some can cause symptoms, particularly neurological ones. Here, we report a case of a two-year-old male child, who presented changes in gait, an alarming sign, during a child health surveillance appointment. On physical examination, the child presented a "duck" gait pattern, axial and appendicular hypotonia, proximal weakness of the pelvic girdle, and a positive Gowers sign. The child was referred to a pediatric neurology appointment where he underwent neuraxial magnetic resonance imaging, identifying a large and expansive formation in the dorsolumbar transition suggestive of neuroblastoma, considering the age group. However, a computed tomography-guided biopsy revealed it to be a paravertebral GN. Tumor resection was performed, leaving some paravertebral tumor residue. After one year of motor rehabilitation, the child had a normal neurological examination. The child is currently five years old and is undergoing annual clinical and imaging surveillance. This case allows us to reflect on the importance of encouraging children and young people to attend recommended surveillance appointments and reminds us that the rarest situations can occur.

Szyduczyński M, Korneliussen J, Landé O, Krakowiak M, Szmuda T, Miękisiak G. Predictors for spinal deformity following resection of intramedullary tumor via posterior approach: a systematic review and meta-analysis. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2023; 32:4355-4361. [PMID: 37805564 DOI: 10.1007/s00586-023-07957-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Revised: 08/29/2023] [Accepted: 09/15/2023] [Indexed: 10/09/2023]
Abstract
PURPOSE The present study aimed to identify the clinical predictive factors for worsened spinal deformity (SD) following surgical resection via posterior approach for primary intramedullary tumors. METHODS A systematic search was performed using PubMed, Web of Science, and Scopus databases to extract potential references. Observational studies reporting predictive factors for worsened SD following surgical resection via posterior approach for primary intramedullary tumors were included. The odds ratio (OR) was calculated for dichotomous parameters. RESULTS Four retrospective cohort studies were included in the meta-analysis. They were comprised of two groups of patients; those who developed SD (n = 87) and those who did not (n = 227). For patients with IMSCTs, age under 25 years as well as age under 13 years were the demographic variables associated with postoperative SD (odds ratio [OR] 3.92; p = 0.0002 and OR 4.22; p = 0.003). In both the fusion and the non-fusion subgroups, preoperative spinal deformity strongly predicted postoperative SD (OR 11.94; p < 0.001), with the risk highly elevated among the non-fusion patients (OR 24.64; p < 0.0002). Thoracolumbar junction involvement was also found to be a predictor of postoperative SD for patients with IMSCT (OR 2.89; p = 0.02). CONCLUSION This study highlights the importance of considering age, preoperative spinal deformity, and thoracolumbar junction involvement as predictors of postoperative spinal deformity following surgical resection for IMSCT. These findings may provide guidance for the management of these patients, including the development of preoperative planning strategies and the selection of the most appropriate surgical approach for high-risk patients.

Abstract
INTRODUCTION Spinal cord surgery has and always will be a challenging operation with satisfying results, but also with potentially devastating results. Over the last century, there has been an evolution in the way we perceive and conduct spinal cord surgery. The phenomenal evolution in technology from the very first x-ray pictures helps to localize the spinal pathology through the use of high-resolution MRI and ultrasonography that allows for high precision surgery with relatively minimal exposure. METHODS The advancements in the surgical technique and the utilization of neuromonitoring allow for maximal safe resection of these delicate and intricate tumors. We also are beginning to understand the biology of spinal cord tumors and vascular lesions, as in the recent 2021 WHO classification which identifies specific entities such as spinal ependymomas, MYCN-amplified, as separate entity from the other subtypes of ependymomas. Surgeons have also accepted the importance of maximal safe resection for most of the spinal cord pathologies rather than just performing biopsy and adjuvant treatment. CONCLUSION There have been significant advances since the first resection of an intramedullary tumor including diagnosis, imaging, and surgical technique for children. These advances have improved the prognosis and outcome in these children.

Abstract
RATIONALE Ganglioneuroma (GN) is a rare tumor that originates from neural crest cells and can manifest in any location along the sympathetic chain. It typically exhibits a circular or oval shape and does not invade the surrounding tissue destructively and the enormous lobular appearance and erosion of adjacent skeletal tissues are extremely infrequent among GN. PATIENT CONCERNS A 15-year-old girl presented to our thoracic surgery clinic with a large intrathoracic mass that was incidentally discovered on a chest X-ray. Further imaging with computed tomography and magnetic resonance imaging revealed a lobular profile and an aggressive growth pattern of the tumor, which destroyed the vertebral and rib bones. A tissue sample obtained by needle biopsy was subjected to histopathological analysis, which confirmed the diagnosis of a GN. DIAGNOSIS Thoracic (posterior mediastinal) GN and Hashimoto's thyroiditis. INTERVENTIONS After thoracoscopic exploration, a thoracotomy was performed to excise the mass. OUTCOMES The patient recovered well after surgery, had no major complications, and was discharged without any issues. Further follow-up is necessary to clarify the medium to long-term outcome. LESSONS Based on existing reports, thoracic GN rarely erodes adjacent bone tissue. By examining previously reported cases, we speculate that the lobular morphology of the tumor may be linked to the more aggressive biological behavior of GN. We also discovered that female patients may be more susceptible to bone erosion. However, further research and additional cases are required to confirm these potential associations.

Abstract
Objective: Long-level intramedullary spinal cord tumors (LIMSCTs) cause complex treatment issues. However, LIMSCTs have rarely been analyzed separately. The authors reported a large case series of LIMSCTs and analyzed the clinical characteristics and treatment outcomes.Methods: The medical data of patients with LIMSCTs at our institution between January 2015 and December 2019 were retrospectively reviewed. Demographics, tumor size and location, pathology, extent of resection, and neurological functional status were collected.Results: A total of 43 consecutive cases were included. Twenty-three cases (53.5%) of LIMSCTs were ependymal tumors. All patients with ependymal tumors achieved gross total resection (GTR). In ependymal tumor cases, 3 cases (13%) of ependymal tumors experienced postoperative neurological deterioration, and 66% of them showed an improvement at follow-up; 25.6% were low-grade astrocytic tumors. The rates of GTR, subtotal resection (STR) and partial resection (PR) were 63.6%, 27.3%, and 9.1%, respectively. Twenty-seven percent cases showed postoperative neurological worsening, and 33% of them had an improvement at follow-up; 20.9% were high-grade astrocytic tumors. The excision rates were 44.4% for GTR, 44.4% for STR, and 11% for PR, respectively. Fifty-five percent cases showed postoperative neurological worsening, and none of them had an improvement at follow-up.Conclusion: In this series, all LIMSCTs were gliomas. Aggressive tumor resection did not increase the risk of long-term functional deterioration in ependymal tumors and low-grade astrocytic tumors, but in high-grade astrocytic tumors, patients had a higher risk of neurological deterioration and difficulty in recovery. In ependymal tumors and low-grade astrocytic tumors, patients can achieve long-time survival after performing aggressive tumor resection.

Abstract
INTRODUCTION Paediatric spinal tumours are rare, accounting for 1-10% of all childhood central nervous system tumours. There is a paucity of information on spinal tumours in Sub-Saharan Africa. This is particularly so in the Nigerian paediatric population where neuro-oncologic data are limited. Indeed, there is no previously published work on paediatric spinal tumours in the Nigerian neurosurgical literature. The authors aim to document the profile of paediatric spinal tumours in a Nigerian tertiary institution and to contribute to the available data on paediatric central nervous system tumours in West Africa. METHODS We retrospectively evaluated data on paediatric patients who underwent surgery for spine tumours over a 20-year period at our institution. RESULTS A total of 12 patients were managed for paediatric spine tumours during the study period. These had a male:female ratio of 1:1.4, and their ages ranged between 3 and 18 years (mean: 12.83 ± 4.75 years). The highest incidence (6/12) was seen in the 15-18 years age group. The mean duration of symptoms was 10.2 months. More than half (7/12) of the patients presented with symptoms with duration of at least 6 months. Motor deficit was present in all patients at presentation. Two-thirds of the tumours were in the thoracic region, 1 was located in the cervical region, while the remaining 3 tumours were cervicothoracic. The tumour was extradural in location in 8 of our patients and intramedullary in the remaining 4. Astrocytoma, intramedullary in all cases, was the most predominant histological tumour type (3/12) in our series. Postoperative neurological improvement occurred in 7 of the patients while 5 remained the same. There was no permanent postoperative neurological deterioration or perioperative mortality. CONCLUSION Paediatric spinal tumours mostly affected older children in our study group and were predominantly astrocytic in nature. The most common tumour location was extradural, involving mostly the thoracic spinal level. The preoperative neurological status correlates with the postoperative functional outcome. Therefore, the need for early diagnosis and treatment of these tumours cannot be overemphasized.

Abstract
(1) Background: spinal tumors not only causes structural problem but also it affects body functionality, too. Surgery has a key role in management of patients with spinal tumor. The aim of this study is that to observe their clinical profile, functional outcomes and prognostic factors. (2) Methods: 20 retrospectively consecutive patients with spinal tumors operated over a period of 2 years were analyzed. (3) Results: nine (45%) were intradural and 11(55%) were extradural. Mean age at surgery was 45.05 years (range 20–80 years). The common clinical features were pain, limb weakness and autonomic involvement. Schwannoma was common in intradural extramedullary group whereas astrocytoma and ependymoma was common in intramedullary group. In this case, 16 (80%) patients had improvement following surgery and 4 (20%) remained the same, none had deterioration. Common complications were persistent pain (1 case) and autonomic involvement (1 case). (4) Conclusion: spinal tumors need early exploration and excision and usually patients recover well without any residual effect.

Abstract
Spinal ganglioneuroma occurs mostly in the thoracic spine causing various manifestations including scoliosis that can be misdiagnosed as idiopathic scoliosis. Few reports exist in the literature on the diagnosis and management of scoliosis secondary to huge ganglioneuroma and usually staged treatment is preferred. In this report, we present a 17-year-old female patient presented with back pain, lower limbs numbness, spinal deformity, and shortness of breath. Plain X-rays showed a 50° right thoracic scoliotic curve. MRI and chest CT revealed a huge extra pulmonary mass shifting the mediastinum with intra spinal extension through the left neural foramina compressing the spinal cord. Percutaneous US guided needle biopsy confirmed the diagnosis of ganglioneuroma. One-stage posterior instrumented correction of scoliosis, spinal cord decompression, and excision of the whole mass from the mediastinum and the spine through posterior approach was done for the patient with smooth postoperative recovery. Chest CT scan was done 2 years after surgery and excluded any local recurrence.

Abstract
BACKGROUND Spinal cord glioma grade IV is a rare, diffuse midline glioma. H3 K27M-mutant was classified in a different entity in the 2016 World Health Organization (WHO) classification recently. No reports about prognosis of spinal cord glioma grade IV are available yet. OBJECTIVE To analyze the prognostic factors for spinal cord glioma grade IV. METHODS Twenty-five patients with spinal cord glioma of grade IV who underwent surgery in a single institute were selected. All grade IV spinal cord glioma histologically confirmed as glioblastoma or "diffuse midline glioma with H3 K27M-mutant" by the 2016 WHO classification of the central nervous system were included. Basic demographics, treatment modalities, and pathological tumor molecular profiles were investigated for prognosis. RESULTS Mean age was 39.1 yr; male to female ratio was 18 : 7. Tumor was located in thoracic cord (53.3%), cervical cord (40%), and lumbar area (6.7%). Median overall survival was 37.1 mo; median disease-free survival was 18.5 mo. Treatment modality showed no statistical difference. Only K27M profile showed significant prognostic value, 20 patients (80%) showed K27M mutation positive, K27M mutation patients showed longer overall survival (40.07 mo) than K27M negative patients (11.63 mo, P < .0001), and disease-free survival (20.85 vs 8.72 mo, P = .0241). CONCLUSION This study is the first and largest report of the prognosis of primary spinal cord grade IV glioma using the new WHO classification. This study reported survival analysis and prognostic factors, and revealed that H3.3 K27M mutation is not a major poor prognostic factor. Further studies to explore K27M mutations needed for risk stratification and therapy optimization.

Abstract
Despite their rare occurrence, intramedullary spinal cord tumors can cause considerable morbidity and mortality without treatment. Timing of surgery, extent of resection and selection of favorable treatment option are important considerations for a good surgical outcome. In this clinical study, we report our patient series and convey our treatment strategy. We retrospectively reviewed 91 patients with primary intramedullary spinal cord tumors who underwent microsurgical resection at our institution between 2008 and 2018. Data were collected consisting of age, sex, location and histology of tumor, extent of resection, presenting symptoms and neurological outcomes. Modified McCormick Scale was used to assess neurological status of patients. 47 female and 44 male patients were followed-up for a mean period of 35.7 months. The most frequent pathological diagnosis was ependymoma in 56 patients, followed by astrocytoma in 21 and hemangioblastoma in 5 patients. The rest of the tumors consisted of 3 cavernomas, 3 mature cystic teratomas, 2 PNET, one epidermoid tumor. Gross total resection was achieved in 67 patients, while subtotal resection and biopsy was performed in 15 and 9 respectively. The most commonly involved localization was cervical (n = 39), followed by thoracic region (n = 24). Despite immediate postoperative worsening of neurological status, a great number of patients improved at the last follow-up. Gross total resection remains the primary goal of treatment while adjuvant radiation and/or chemotherapy may be alternative options for high grade tumors. Preoperative neurological status was the most important and the strongest predictor of functional outcome.

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
OBJECTIVE Pediatric spinal astrocytomas are rare spinal lesions that pose unique management challenges. Therapeutic options include gross-total resection (GTR), subtotal resection (STR), and adjuvant chemotherapy or radiation therapy. With no randomized controlled trials, the optimal management approach for children with spinal astrocytomas remains unclear. The aim of this study was to conduct a systematic review and meta-analysis on pediatric spinal astrocytomas. METHODS The authors performed a systematic review of the PubMed/MEDLINE electronic database to investigate the impact of histological grade and extent of resection on overall survival among patients with spinal cord astrocytomas. They retained publications in which the majority of reported cases included astrocytoma histology. RESULTS Twenty-nine previously published studies met the eligibility criteria, totaling 578 patients with spinal cord astrocytomas. The spinal level of intramedullary spinal cord tumors was predominantly cervical (53.8%), followed by thoracic (40.8%). Overall, resection was more common than biopsy, and GTR was slightly more commonly achieved than STR (39.7% vs 37.0%). The reported rates of GTR and STR rose markedly from 1984 to 2015. Patients with high-grade astrocytomas had markedly worse 5-year overall survival than patients with low-grade tumors. Patients receiving GTR may have better 5-year overall survival than those receiving STR. CONCLUSIONS The authors describe trends in the management of pediatric spinal cord astrocytomas and suggest a benefit of GTR over STR for 5-year overall survival.

Abstract
INTRODUCTION Spinal cord tumors in children (SCTC) are rare with a frequent diagnostic delay. Its management is multidisciplinary and challenging due to functional implications. The position of surgery is now better established but the role and timing of chemotherapy (CT) and radiotherapy (RT) still remains under debate. Adverse effects of treatments are important to be taken into account, in the follow-up of these children. The aim of this paper was to present a series of 21 cases of SCTC treated at the same institution, to briefly present clinical features, treatments and outcome, with a special focus on spinal deformities in children with this condition. MATERIAL AND METHODS Twenty-one consecutive SCTC were referred to our institution from 1990 to 2014. Data regarding age, sex, diagnostic delay, clinical examination, MRI, surgery, pathology, other treatment (CT and RT), orthopedic issues and follow-up of these children were retrospectively recorded. RESULTS Mean age was 8years (standard deviation: 5.2years) (range: 4 months-17years). Mean diagnosis delay was 5.5 months (standard deviation: 6.5 months) (range: 0 days-18 months). All children (10 girls, 11 boys) were operated on (10 partial removals, 7 subtotal and 4 gross total removals) as first-line treatment. Pathological results showed 12 juvenile pilocytic astrocytomas, 1 grade III astrocytoma, 1 grade IV astrocytoma, 3 oligodendrogliomas, 2 ependymomas, 1 glioblastoma and 1 rhabdoid tumor. Fourteen children (66.7%) received additional treatment: 12 CT and 7 RT. Ten children had postoperative spinal deformities. Mean follow-up (FU) was 71 months (5 months-180 months), with a median FU at 60 months, where 8 tumor progressions and 4 deaths were observed. Overall, survival (at 5years) was 81% and progression free survival (at 5years) was 67%. CONCLUSION Surgery is the goal standard for SCTC and the only appropriate treatment in cases of a low-grade lesion with stable disease on MR follow-up. Additional treatment must be reserved for high-grade lesions or tumor progression not attainable by a second look surgery. Spinal deformities are a frequent complication. Overall, survival and event free survival primarily depends on the pathology. Studies involving more centers are obligatory with the aim of collecting more cases and drawing more definitive conclusions regarding the management of these tumors.

Abstract
Abstract
BACKGROUND AND IMPORTANCE: Pilocytic astrocytoma (PA) is among the most common of the central nervous system gliomas in the pediatric population; however, it is uncommon in adults. PAs of the spinal cord in adults are even rarer, with only a few cases found in the literature. We report here the first case in the literature of multifocal intradural extramedullary spinal cord PAs in an adult.
CLINICAL PRESENTATION: Our patient is a 56-yr-old female who presented with loss of balance and an ataxic gait. Multiple extramedullary spinal cord tumors were identified intraoperatively, the lesions completely resected, and all diagnosed as PAs.
CONCLUSION: This case illustrates a unique instance of multifocal intradural extramedullary spinal cord PAs in an adult with no previous history of PA during childhood, no known familial syndromes, and no brain involvement.

Abstract
OBJECTIVE Surgical excision is the mainstay treatment for resectable low-grade intramedullary spinal cord tumors (IMSCTs) in the pediatric age group. Chemotherapy and radiation treatments are generally reserved for progressive or recurrent disease. Given the indolent nature of low-grade tumors and the potential side effects of these approaches, their long-term treatment benefits are unclear. The aim of the study was to determine long-term disease outcomes and the therapeutic roles of surgery and adjuvant therapies in pediatric patients with low-grade IMSCTs over an extended follow-up period. METHODS Case records for all pediatric patients (< 21 years of age) with a histopathological diagnosis of low-grade IMSCT were selected over a period from January 1975 to January 2010. Outcome variables including McCormick functional grade, overall survival (OS), and progression-free survival (PFS) were analyzed with respect to demographic and treatment variables. RESULTS Case records of 37 patients with low-grade IMSCTs were identified, with a mean follow-up duration of 12.3 ± 1.4 years (range 0.5-37.2 years). Low-grade astrocytomas were the most prevalent histological subtype (n = 22, 59%). Gross-total resection (GTR) was achieved in 38% of patients (n = 14). Fusion surgery was required in 62% of patients with pre- or postoperative deformity (10 of 16). On presentation, functional improvement was observed in 87% and 46% of patients in McCormick Grades I and II, respectively, and in 100%, 100%, and 75% in Grades III, IV, and V, respectively. Kaplan-Meier PFS rates were 63% at 5 years, 57% at 10 years, and 44% at 20 years. OS rates were 92% at 5 years, 80% at 10 years, and 65% at 20 years. On multivariate analysis, shunt placement (hazard ratio [HR] 0.33, p = 0.01) correlated with disease progression. There was a trend toward improved 5-year PFS in patients who received adjuvant chemotherapy and radiation therapy (RT; 55%) compared with those who did not (36%). Patients who underwent subtotal resection (STR) were most likely to undergo adjuvant therapy (HR 7.86, p = 0.02). CONCLUSIONS This extended follow-up duration in patients with low-grade IMSCTs beyond the first decade indicates favorable long-term OS up to 65% at 20 years. GTR improved PFS and was well tolerated with sustained functional improvement in the majority of patients. Adjuvant chemotherapy and RT improved PFS in patients who underwent STR. These results emphasize the role of resection as the primary treatment approach, with adjuvant therapy reserved for patients at risk for disease progression and those with residual tumor burden.

Abstract
Paravertebral ganglioneuroma and scoliosis is a rare clinical benign disease. The case we reported is about a 12-year-old girl who was hospitalized due to neoplasm with spinal deformity in the right abdomen for 1 month. Based on a careful preoperative evaluation and found no obvious surgery contraindications, the patient was treated with surgical resection of the tumor and correction of the deformity by surgery. Postoperative pathologic examination confirmed it was a ganglioneuroma. After the operation, the patient recovered well. Her spinal deformity was corrected, and she was 5 cm taller. Complete resection of ganglioneuroma following with a low recurrence rate and a good prognosis, patient does not need further chemotherapy, radiation therapy, or other treatments. All follow-up radiographic studies demonstrated no relapse of the tumor in the following 18 months. Combining this case with similar cases at home and aboard and reviewing related literature, we formed conclusions based on the manifestations, diagnosis, treatment, and prognosis of this disease and provided treatments for similar cases.

Abstract
Pilocytic astrocytoma (PA) is the most common pediatric brain tumor in children. PAs are a distinct histologic and biologic subset of glioma that have a slow growth rate and may even spontaneously regress. These tumors tend to arise in the cerebellum and chiasmatic/hypothalamic region, but can also occur in other regions of the central nervous system. Dissemination is uncommon, but may occur in newly diagnosed PAs. Alterations in the Ras/RAF/mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) pathway (Ras/ERK) have been discovered in a majority of PAs, with KIAA1549-BRAF fusions being the most commonly identified alteration. Children with neurofibromatosis 1 are predisposed to developing PAs, primarily within the optic pathway. When required, treatment consists of surgery, chemotherapy, and/or radiation, although new molecular agents targeting the Ras/ERK and related signaling pathways are promising new approaches. The 10-year survival rates are greater than 90% in pediatric patients; however, they are poorer in adults. Tumors that are amenable to complete resection (i.e., cerebellum and cortex) have the best overall survival.

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
Introduction and Methods: We retrospectively analyzed 111 patients with spinal tumors operated over a period of 9 years to observe the relative frequency of different lesions, their clinical profile, functional outcome and prognostic factors. 30/111 (27%) were extradural, 40/111 (36.1%) were intradural extramedullary (IDEM) and 41/111 (36.9%) were intramedullary spinal cord tumors (IMSCTs). Mean age at surgery was 30.81 years (range 1–73 years). The average preoperative duration of symptoms was 16.17 months (15 days to 15 years). Major diagnoses were ependymomas and astrocytomas in IMSCT group, schwanommas and neurofibromas in IDEM group, and metastasis, lymphoma in extradural group. The common clinical features were motor weakness in 78/111 (70.27%), sensory loss in 55/111 (49.54%), pain 46/111 (41.44%), and sphincter involvement in 47/111 (42.43%) cases. Results: Totally, 88/111 (79.27%) patients had improvement in their functional status, 17/111 (15.31%) remained same, and 6/111 (5.4%) were worse at time of their last follow-up. The mean follow-up was 15.64 months (1.5 m−10 years). Totally, 59 out of 79 patients, who were dependent initially, were ambulatory with or without the aid. Most common complication was persistent pain in 10/111 (9%) patients and nonimprovement of bladder/bowel symptoms in 7/111 (6.3%). One patient died 3 months after surgery. Conclusions: (1) Congenital malformative tumors like epidermoids/dermoids (unrelated to spina bifida) occur more frequently, whereas the incidence of spinal meningioma is less in developing countries than western populations. (2) The incidence of intramedullary tumors approaches to that of IDEM tumors. Intramedullary tumors present at a younger age in developing countries. (3) Rare histological variants like primitive neuroectodermal tumors should also be considered for histological differential diagnosis of spinal tumors. (4) Preoperative neurologic status is the most important factor related to outcome in spinal tumors.

Abstract
BACKGROUND CONTEXT Spinal tumors in childhood are rare and heterogeneous, and their treatment is very demanding. It is necessary to both manage the disease and preserve the spinal stability so that the spine can grow normally. As a consequence, results in terms of both mortality and morbidity are often suboptimal. PURPOSE The results of a single pediatric neurosurgery institution are reported to highlight the peculiarities and pitfalls of the management of this disease. Tumors are analyzed from the point of view of their localization, histology, and outcome in terms of mortality and morbidity, with a special focus on postoperative spinal deformity. STUDY DESIGN The study design was retrospective. PATIENT SAMPLE Between 1995 and 2011, 134 children (75 males and 59 females) were admitted for spinal tumors, accounting for 7.7% of all the patients admitted for central nervous system malignancies. The mean age was 8.5 years (14 days-26 years), and the mean follow-up was 28 months (3 months-13 years). OUTCOME MEASURES Clinical and radiological outcomes were evaluated to assess mortality, morbidity, and surgical outcomes. A special interest was directed toward morbidity related to spinal deformity and neurologic deficits. METHODS Patients were divided into four groups: intramedullary (46 patients), intradural extramedullary (25 patients), extradural (53 patients), and paravertebral tumors (10 patients). Data were obtained retrospectively from medical records and radiological archives. RESULTS Low-grade glioma was the most common histology (14.1%). One hundred seventeen patients were surgically treated, with a total of 138 surgical procedures. A posterior approach was chosen in 111 cases, with osteoplastic laminotomy in 80. Radiotherapy was administered to 22 patients and chemotherapy to 26. At the last follow-up, 16 patients (11.9%) had died. A good control of the tumor with clinical improvement was reported in 100 patients (74.6%). Five patients developed a spinal instability (3.7%). CONCLUSIONS The goals of surgery should be histology, spine and nerve root decompression, and preservation of spinal stability. In our experience, osteoplastic laminotomy was a good surgical approach to perform the resection of the tumor with a low risk of secondary spinal instability.

Abstract
OBJECT Grade II spinal cord ependymomas occurring in pediatric patients are exceptionally rare neoplasms. In this paper the authors use a national cancer database to determine patient demographics, treatment patterns, and associated outcomes of this cohort. METHODS The Surveillance Epidemiology and End Results (SEER) database was used to analyze subjects younger than 18 years with histologically confirmed diagnoses of Grade II spinal cord ependymoma from the years 1973 to 2008. Descriptive data on the demographic characteristics of this cohort and the associated treatment patterns are shown. The Kaplan-Meier method was used to estimate overall survival at 1, 2, 5, and 10 years. RESULTS This cohort comprised 64 pediatric subjects with Grade II spinal ependymoma. The median age was 13 years, nearly half of the patients were male, and most were white (84%). The median follow-up was 9.2 years. Overall survival at 5 and 10 years was 86% and 83%, respectively. Gross-total resection was achieved in 57% of subjects, and radiation therapy was administered to 36%. Radiation therapy was administered to 78% of subjects after subtotal resection but only to 19% of patients after gross-total resection; this difference was significant (p < 0.001). In a multivariate regression model analyzing sex, age at diagnosis, year of diagnosis, radiotherapy, and extent of resection, female sex was found to be an independent predictor of decreased mortality (HR 0.15 [95% CI 0.02-0.94], p = 0.04). CONCLUSIONS These data show long-term outcomes for pediatric patients with Grade II spinal ependymoma. Radiotherapy was more likely to be administered in cases of subtotal resection than in cases of gross-total resection. Female sex is associated with decreased mortality, while other demographic or treatment modalities are not.

Abstract
OBJECT Intraoperative dorsal column mapping, transcranial motor evoked potentials (TcMEPs), and somatosensory evoked potentials (SSEPs) have been used in adults to assist with the resection of intramedullary spinal cord tumors (IMSCTs) and to predict postoperative motor deficits. The authors sought to determine whether changes in MEP and SSEP waveforms would similarly predict postoperative motor deficits in children. METHODS The authors reviewed charts and intraoperative records for children who had undergone resection for IMSCTs as well as dorsal column mapping and TcMEP and SSEP monitoring. Motor evoked potential data were supplemented with electromyography data obtained using a Kartush microstimulator (Medtronic Inc.). Motor strength was graded using the Medical Research Council (MRC) scale during the preoperative, immediate postoperative, and follow-up periods. Reductions in SSEPs were documented after mechanical traction, in response to maneuvers with the cavitational ultrasonic surgical aspirator (CUSA), or both. RESULTS Data from 12 patients were analyzed. Three lesions were encountered in the cervical and 7 in the thoracic spinal cord. Two patients had lesions of the cervicomedullary junction and upper spinal cord. Intraoperative MEP changes were noted in half of the patients. In these cases, normal polyphasic signals converted to biphasic signals, and these changes correlated with a loss of 1-2 grades in motor strength. One patient lost MEP signals completely and recovered strength to MRC Grade 4/5. The 2 patients with high cervical lesions showed neither intraoperative MEP changes nor motor deficits postoperatively. Dorsal columns were mapped in 7 patients, and the midline was determined accurately in all 7. Somatosensory evoked potentials were decreased in 7 patients. Two patients each had 2 SSEP decreases in response to traction intraoperatively but had no new sensory findings postoperatively. Another 2 patients had 3 traction-related SSEP decreases intraoperatively, and both had new postoperative sensory deficits that resolved. One additional patient had a CUSA-related SSEP decrease intraoperatively, which resolved postoperatively, and the last patient had 3 traction-related sensory deficits and a CUSA-related sensory deficit postoperatively, none of which resolved. CONCLUSIONS Intraoperative TcMEPs and SSEPs can predict the degree of postoperative motor deficit in pediatric patients undergoing IMSCT resection. This technique, combined with dorsal column mapping, is particularly useful in resecting lesions of the upper cervical cord, which are generally considered to be high risk in this population. Furthermore, the spinal cord appears to be less tolerant of repeated intraoperative SSEP decreases, with 3 successive insults most likely to yield postoperative sensory deficits. Changes in TcMEPs and SSEP waveforms can signal the need to guard against excessive manipulation thereby increasing the safety of tumor resection.

Abstract
OBJECT Radical resection is recommended as the first-line treatment for pediatric intramedullary spinal cord tumors (IMSCTs), but it is associated with morbidity, including risk of neurological decline and development of postoperative spinal deformity. The authors report long-term data on clinical and treatment determinants affecting disease survival and neurological outcomes. METHODS Case records for pediatric patients (< 21 years of age at presentation) who underwent surgery for IMSCTs at the authors' institution between January 1975 and January 2010 were analyzed. The patients' demographic and clinical characteristics (including baseline neurological condition), the treatment they received, and their disease course were reviewed. Long-term disease survival and functional outcome measures were analyzed. RESULTS A total of 55 patients (30 male and 25 female) were identified. The mean duration of follow-up (± SEM) was 11.4 ± 1.3 years (median 9.3 years, range 0.2-37.2 years). Astrocytomas were the most common tumor subtype (29 tumors [53%]). Gross-total resection (GTR) was achieved in 21 (38%) of the 55 patients. At the most recent follow-up, 30 patients (55%) showed neurological improvement, 17 (31%) showed neurological decline, and 8 (15%) remained neurologically stable. Patients presenting with McCormick Grade I were more likely to show functional improvement by final follow-up (p = 0.01) than patients who presented with Grades II-V. Kaplan-Meier actuarial tumor progression-free survival rates at 5, 10, and 20 years were 61%, 54%, and 44%, respectively; the overall survival rates were 85% at 5 years, 74% at 10 years, and 64% at 20 years. On multivariate analysis, GTR (p = 0.04) and tumor histological grade (p = 0.02) were predictive of long-term survival; GTR was also associated with improved 5-year progression-free survival (p = 0.01). CONCLUSIONS The prognosis for pediatric IMSCTs is favorable with sustained functional improvement expected in a significant proportion of patients on long-term follow-up. Long-term survival at 10 years (75%) and 20 years (64%) is associated with aggressive resection. Gross-total resection was also associated with improved 5-year progression-free survival (86%). Hence, the treatment benefits of GTR are sustained on extended follow-up.

Abstract
We retrospectively reviewed the outcomes of 195 patients with intramedullary tumors who underwent surgery between January 2001 and December 2010 at a single institution. The symptomatology, neurological and neuroradiological findings, operative details, perioperative and postoperative complications, histopathological data and follow-up examinations of the 137 (70.2%) males and 58 (29.7%) females were studied and analyzed. Epidermoid was the most common intramedullary tumour in children (23%), whereas in adults, ependymomas were more common (46%). Ependymomas were more amenable to resection (total excision in 57.7% and near-total excision in 39.4%) as compared to astrocytomas (total excision in 29%; near total excision in 60.5%). At the final clinical follow-up, 24 patients (16.4%) had improved in McCormick grade, 112 patients (76.7%) remained unchanged and 11 patients (7.5%) had worsened. Complete removal of the lesion is the primary goal of surgery. We conclude that the strongest predictor of functional outcome was the preoperative neurological condition, beyond the histological differentiation of the intramedullary tumor.

Abstract
INTRODUCTION Intramedullary tumors are rare and comprise only a small percentage of all central nervous system neoplasms. There has been much controversy with the surgical management of these tumors. This study presents detailed information regarding clinical presentation, histological findings, outcomes, functional assessment, and management of a series of patients with this diagnosis. METHODS The authors reviewed 82 cases of up to 18 years of age operated between 2001 and 2010. The symptomatology, neurological and neuroradiological findings, operative details, perioperative and postoperative complications, histopathological data, and follow-up examinations were studied and analyzed. RESULTS There were 57 (69.5 %) males and 25 (30.4 %) females. Overall, epidermoid (20.7 %) constituted the most common tumor followed by low-grade gliomas and ependymoma (19.5 % each). Near total resection for epidermoid and dermoid was possible in 82.3 % and 60 % cases, respectively. Ependymomas were more amenable for gross total excision (43.7 %) as compared to pilocytic astrocytomas (22.2 %); however, near total resection was possible in another 50 % and 66.6 % cases, respectively. At the last clinical evaluation on follow-up, 8 patients (14.2 %) had improved in their grades, 46 patients (82.1 %) remained unchanged, and 2 patients (3 %) worsened. CONCLUSION Complete removal of the lesion is the primary goal. In our experience, we conclude that the strongest predicting factor of functional outcome was the preoperative neurological condition beyond the histological differentiation of the intramedullary tumors.

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
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
Intramedullary tumors are rare. The authors reviewed 24 cases operated between 1996 and 2006. The study assessed the clinical characteristics and surgical results based upon the neurological function. METHOD: Medical records of patients with intramedullary astrocytoma and ependymoma were reviewed. The minimal follow up time was 6 months and, at the end of this period, a comparative analysis of the neurological function was performed based using the McCormick scale score. RESULTS: Most patients had astrocytoma (75%). Male gender was more prevalent (58.3%). The most common type of tumor was graded as I or II, and in three cases these were malignant. The total resection of the tumor was achieved in 20.8% of the cases. The statistical analysis did not show a statistically significant difference between preoperative and postoperative grades at McCormick scale. CONCLUSION: The authors concluded that microsurgery to intramedullary tumors did not significantly alter the neurological function after six months.

Abstract
OBJECT With the introduction of electrophysiological spinal cord monitoring, surgeons have been able to perform radical resection of intramedullary spinal cord tumors (IMSCTs). However, factors associated with tumor resectability, tumor recurrence, and long-term neurological outcome are poorly understood. METHODS The authors retrospectively reviewed 101 consecutive cases of IMSCT resection in adults and children at a single institution. Neurological function and MR images were evaluated preoperatively, at discharge, 1 month after surgery, and every 6 months thereafter. Factors associated with gross-total resection (GTR), progression-free survival (PFS), and long-term neurological improvement were assessed using multivariate regression analysis. RESULTS The mean age of the patients was 41 +/- 18 years and 17 (17%) of the patients were pediatric. Pathological type included ependymoma in 51 cases, hemangioblastoma in 15, pilocytic astrocytoma in 16, WHO Grade II astrocytoma in 10, and malignant astrocytoma in 9. A GTR was achieved in 60 cases (59%). Independent of histological tumor type, an intraoperatively identifiable tumor plane (OR 25.3, p < 0.0001) and decreasing tumor size (OR 1.2, p = 0.05) were associated with GTR. Thirty-four patients (34%) experienced acute neurological decline after surgery (associated with increasing age [OR 1.04, p = 0.02] and with intraoperative change in motor evoked potentials [OR 7.4, p = 0.003]); in 14 (41%) of these patients the change returned to preoperative baseline within 1 month. In 31 patients (31%) tumor progression developed by last follow-up (mean 19 months). Tumor histology (p < 0.0001) and the presence of an intraoperatively identified tumor plane (hazard ratio [HR] 0.44, p = 0.027) correlated with improved PFS. A GTR resulted in improved PFS for hemangioblastoma (HR 0.004, p = 0.04) and ependymoma (HR 0.2, p = 0.02), but not astrocytoma. Fifty-five patients (55%) maintained overall neurological improvement by last follow-up. The presence of an identifiable tumor plane (HR 3.1, p = 0.0004) and improvement in neurological symptoms before discharge (HR 2.3, p = 0.004) were associated with overall neurological improvement by last follow-up (mean 19 months). CONCLUSIONS Gross-total resection can be safely achieved in the vast majority of IMSCTs when an intraoperative plane is identified, independent of pathological type. The incidence of acute perioperative neurological decline increases with patient age but will improve to baseline in nearly half of patients within 1 month. Long-term improvement in motor, sensory, and bladder dysfunction may be achieved in a slight majority of patients and occurs more frequently in patients in whom a surgical plane can be identified. A GTR should be attempted for ependymoma and hemangioblastoma, but it may not affect PFS for astrocytoma. For all tumors, the intraoperative finding of a clear tumor plane of resection carries positive prognostic significance across all pathological types.

Abstract
OBJECTIVES The objective of this manuscript is to discuss current management strategies regarding pediatric patients with intramedullary spinal cord ependymomas. Spinal ependymoma is the second most common spinal cord tumor in children. The clinical evaluation of these patients, operative techniques, postoperative management considerations, and long-term outcomes are discussed. INTRODUCTION The gold standard for the treatment of spinal ependymoma continues to be gross total resection. Patients with residual tumor postoperatively may benefit from adjuvant radiation therapy. Intraoperative monitoring is critical to minimize permanent postoperative neurologic deficit. CONCLUSION Patients requiring multilevel laminectomy may benefit from concomitant laminoplasty or instrumented fusion to avoid progressive spinal column deformity.

Abstract
OBJECT Intramedullary spinal cord low-grade gliomas (LGGs) are rare CNS neoplasms in pediatric patients, and there is little information on therapy for and outcome of these tumors in this population. Furthermore, most patient series combine adult and pediatric patients or high- and low-grade tumors, resulting in controversial data regarding optimal treatment of these children. To clarify these issues, the authors performed a regional population-based study of spinal cord LGGs in pediatric patients. METHODS All pediatric patients with LGGs treated during the MR imaging era (1985-2007) were identified in the comprehensive database of the Hospital for Sick Children in Toronto. Data on demographics, pathology, treatment details, and outcomes were collected. RESULTS Spinal cord LGGs in pediatric patients constituted 29 (4.6%) of 635 LGGs. Epidemiological and clinical data in this cohort were different than in patients with other spinal tumors and strikingly similar to data from pediatric patients with intracranial LGGs. The authors observed an age peak at 2 years and a male predominance in patients with these tumors. Histological testing revealed a Grade I astrocytoma in 86% of tumors. Although 5-year progression-free survival for the entire group was 48 +/- 9%, all patients were alive at a median follow-up of 8.2 years. Five-year progression-free survival was 88 +/- 13% for patients undergoing gross-total resection and 34 +/- 11% for those undergoing all other therapies, respectively (p = 0.02). Chemotherapy and radiation therapy showed similar efficacy, achieving sustained tumor control in most patients. However, this excellent survival rate was associated with an 83% rate of significant neurological and orthopedic sequelae. CONCLUSIONS This study provides basic data on the incidence, clinical course, and outcome of spinal cord LGGs in pediatric patients. The similarities between spinal and intracranial LGGs in pediatric patients showing excellent survival but high morbidity suggest that a less aggressive approach may be the preferable treatment option for these patients.

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
To determine the relationship between clinical presentation, radiographic features, pathology, and treatment on overall survival of newly diagnosed pediatric primary spinal cord tumors (PSCT). Retrospective analysis of all previously healthy children with newly diagnosed PSCT at a single institution from 1995 to present was performed. Twenty-five pediatric patients (15 boys, average 7.9 years) were diagnosed with PSCT. Presenting symptoms ranged from 0.25 to 60 months (average 7.8 months). Symptom duration was significantly shorter for high grade tumors (average 1.65 months) than low grade tumors (average 11.2 months) (P = 0.05). MRI revealed tumor (8 cervical, 17 thoracic, 7 lumbar, 7 sacral) volumes of 98–94,080 mm3 (average 19,474 mm3). Homogeneous gadolinium enhancement on MRI correlated with lower grade pathology (P = 0.003). There was no correlation between tumor grade and volume (P = 0.63) or edema (P = 0.36) by MRI analysis. Median survival was 53 months and was dependent on tumor grade (P = 0.05) and gross total resection (P = 0.01) but not on gender (P = 0.49), age of presentation (P = 0.82), duration of presenting symptoms (P = 0.33), or adjuvant therapies (P = 0.17). Stratified Kaplan–Meier analysis confirmed the association between degree of resection and survival after controlling for tumor grade (P = 0.01). MRI homogeneous gadolinium enhancement patterns may be helpful in distinguishing low grade from high grade spinal cord malignancies. While tumor grade and gross total resection rather than duration of symptoms correlated with survival in our series, greater than one-third of patients had reported symptoms greater than 6 months duration prior to diagnosis.

Abstract
Object
The authors investigated the outcome of intramedullary spinal cord tumor surgery, focusing on the effect of preoperative neurological status on postoperative mobility and the extent of tumor excision guided by intraoperative spinal cord monitoring prospectively.
Methods
Intramedullary spinal cord tumor surgery was performed in 131 patients between 1997 and 2007. The authors compared the pre- and postoperative neurological status and examined the type of surgery in 106 of these patients. A modified McCormick Scale (Grades I–V) was used to assess ambulatory ability (I = normal ambulation; II = mild motor sensory deficit, independent without external aid; III = independent with external aid; IV = care required; and V = wheelchair required). The type of surgery was classified into 4 levels: total resection, subtotal resection, partial resection, and biopsy.
Results
The 106 patients consisted of 47 females and 59 males, whose average age was 42.5 years (range 6–75 years). The mean follow-up period was 7.3 years (range 2.5 months–21 years). The tumor types included astrocytoma (12 cases), ependymoma (46 cases), hemangioblastoma (16 cases), cavernous hemangioma (17 cases), and others (15 cases overall: gangliocytoma, 1; germ cell tumor, 1; lymphoma, 3; neurinoma, 1; meningioma, 1; oligodendroglioma, 1; sarcoidosis, 2; glioma, 1; and unknown, 4). Initial total excision, subtotal resection, partial resection, biopsy, and duraplasty were performed in 59, 12, 22, 12, and 1 patients, respectively. According to the preoperative McCormick Scale, ambulatory status was classified as Grades I, II, III, IV, and V in 41(38%), 30 (28%), 14 (13%), 19 (19%), and 2 (2%) patients, respectively. Thirty-three (31%) of 106 patients suffered postoperative neurological deterioration. The number of patients who did not lose ambulatory ability or who achieved an ambulatory status of Grade I or II postoperatively was 33 (80%), 21 (70%), 10 (71%), 8 (42%), and 1 (50%) in patients with preoperative Grades I, II, III, IV, and V, respectively. Total excision was performed in 31 (79%) of 39 patients with preoperative Grade I, 12 (40%) of 30 patients with Grade II, 7 (50%) of 14 patients with Grade III, and 9 of 21 patients (38%) with Grade IV or V, indicating that the rate of total excision was significantly higher in patients with Grade I status.
Conclusions
The postoperative ambulatory ability was excellent in patients with a good preoperative neurological status. Total excision in patients with Grade I or II ambulation was associated with a good prognosis for postoperative mobility. However, the rate of postoperative deterioration was 31.5%, which is relatively high, and patients should be fully informed of this concern prior to intramedullary spinal cord tumor surgery.

Abstract
ABSTRACT
OBJECTIVE
The optimal management of malignant intramedullary spinal cord astrocytomas remains controversial. Although radiotherapy has become the standard of care, the relationship between extent of resection and survival remains unclear. We report the outcomes of the surgical management of 35 malignant spinal cord astrocytomas and assess the association of extent of resection with survival after aggressive resection of these tumors.
METHODS
An institutional intramedullary spinal cord tumor database (1990–2002) was reviewed to identify all patients treated for malignant astrocytomas of the spinal cord (anaplastic astrocytoma [AA] or glioblastoma multiforme [GBM]). Length of survival from surgery was charted by Kaplan-Meier plots, and association of extent of resection with survival was assessed via log rank analysis for stratified covariates and Cox proportional-hazards model for continuous covariates.
RESULTS
Twenty-seven (77%) and eight (23%) patients underwent resection of AA and GBM, respectively. Mean age was 29 ±16 years (range, 2–61 yr). Tumor involved six ± four vertebral levels. For AA cases, radical resection (no residual postoperative magnetic resonance enhancement) was achieved in 12 (44%) patients and subtotal resection (residual postoperative magnetic resonance enhancement) was achieved in 15 (56%). No GBM patients underwent radical resection (mean estimated resection, 70%). After surgery, two (6%) patients improved neurologically by modified McCormick score, 19 (54%) remained stable, and 14 (40%) declined. Median overall survival for AA patients was 72 months (85% at 1 yr; 59% at 5 yr). Median overall survival for GBM patients was 9 months (31% at 1 yr; 0% at 5 yr). Subtotal versus radical resection of AA was associated with decreased overall survival (38 versus 78% at 4 yr, P = 0.028). Postoperative tumor dissemination was associated with decreased survival (P = 0.004). When adjusting for multiple comparisons (P < 0.006 needed for significance), a trend of increased survival was observed with radical resection (P = 0.023).
CONCLUSION
Neurological function can be preserved with aggressive resection of malignant intramedullary spinal astrocytomas; however, motor decline may be observed in many cases. Radical resection of AA was associated with a trend of increased overall survival in nondisseminated AA cases. Radical surgery and radiotherapy of GBM was associated with poor survival, similar to historical controls of diagnostic biopsy and radiotherapy. A markedly shorter survival may be expected in cases in which AA disseminates along the neuraxis. Biopsy alone may not provide the best outcomes for patients with malignant spinal cord tumors.

Abstract
BACKGROUND Spinal cord compression by pediatric intraspinal tumors may result in persisting neurological deficits. The impact such late effects have on social and psychological adjustment and quality of life has not been documented previously. METHOD To study the long-term outcome of pediatric patients with intraspinal tumors, we followed 28 consecutive patients under 16 years of age who were treated in a single institution from 1975 to 2005. In 20 of 26 survivors (median follow-up time 8.4 years, range 0.8-31.3 years) who agreed to participate, neurological, orthopedic, and cognitive complications and their impact on behavioral and psychological adjustment, and health-related quality of life (HRQoL) were comprehensively assessed qualitatively and quantitatively. Primary therapy for spinal cord decompression was surgery in ten patients, chemotherapy in nine, and radiotherapy in one. RESULTS Tumor control was good (10-year overall survival rate of 96%; 10-year progression-free survival rate of 84%). Persistent neurological complications occurred in 10 (50%) patients (paraparesis, n = 7; monoparesis, n = 3; neurogenic bladder dysfunction, n = 4; neurogenic bowel dysfunction, n = 2). Two of the ten patients with paresis depended on wheelchair. Seven (35%) patients developed scoliosis and six of these required spondylodesis. Survivors reported no major impairments in daily activities and rated their HRQoL only slightly lower than healthy controls. The only statistically significant difference was in emotional functioning. DISCUSSION Most patients with intraspinal tumors have a good chance of cure. Apart from few patients, especially those with severe neurological complications, self-rated HRQoL is comparable to that of healthy controls.

Abstract
Postlaminectomy spinal deformity is a frequent problem after resection of a pediatric spinal cord tumor. However, the use of spinal fusion done at the time of resection in preventing the development of deformity is unknown. The purpose of our study was to assess the effectiveness of single-stage laminectomy, spinal cord decompression, and fusion for the prevention of postlaminectomy spinal deformity in children with intramedullary spinal cord tumors. Clinical charts and radiographs of 33 children with spinal cord tumors were reviewed for treatment description, preoperative spinal alignment, postoperative spinal alignment, and subsequent medical and surgical treatment. Spinal deformity was graded by predefined criteria. Significant spinal deformity developed in 10 of 17 children with laminectomy only, 3 of 4 children with laminoplasty, and 3 of 12 children with spinal fusion (2/6 with instrumentation, 1/6 with in situ fusion). Excluding patients that progressed to paraplegia, 9 of 16 patients treated with resection without fusion compared with 1 of 10 patients treated with resection and fusion developed a spinal deformity (P = 0.04). Among skeletally mature children that did not progress to paraplegia, 9 of 15 treated with resection without fusion compared with 1 of 7 patients treated with resection and fusion developed a deformity (P = 0.05). Removal of greater than 4 laminae (P = 0.03) was found to be associated with the development of postresection spinal deformity.

Abstract
Childhood spinal cord astrocytomas are rare diseases, and their management is controversial. We report here our successful experience using irinotecan and cisplatin in three consecutive infants with progressing intramedullary astrocytomas. The first patient was a 16-month-old girl who presented with a grade III intramedullary astrocytoma that rapidly progressed after surgery and adjuvant chemotherapy. Weekly irinotecan (50 mg/m(2)) and cisplatin (30 mg/m(2)) for four consecutive weeks (one cycle) for a total of four cycles (I/C regimen) was used in order to avoid or delay radiotherapy. Radiological complete remission was achieved 10 months after completion of therapy, and 3.5 years after diagnosis the patient remains disease free. The second patient was a 19-month-old boy with a C3-T4 grade II intramedullary astrocytoma who received up-front vincristine and carboplatin for two months but remained clinically symptomatic. A followup MRI showed a larger tumor, and the patient was switched to the I/C regimen. A marked clinical improvement occurred after the first cycle, and MRI showed a very good partial remission at the end of therapy. At 16 months after diagnosis, the patient remains disease free. The third patient was a 10-month-old girl with a C2-T3 grade II intramedullary astrocytoma. She presented with severe pain that became steroid dependent during the month she was treated with the vincristine-carboplatin regimen. When she was switched to the I/C regimen, the clinical symptoms responded within days. MRI at the end of therapy showed a significant reduction in tumor size, and one year after diagnosis the patient remains symptom free. Using this I/C regimen for childhood intramedullary astrocytoma, we obtained remarkable clinicoradiological responses while avoiding the use of radiotherapy.

Abstract
Abstract
OBJECTIVE:
The value of intraoperative neurophysiological monitoring (INM) during intramedullary spinal cord tumor surgery remains debated. This historical control study tests the hypothesis that INM monitoring improves neurological outcome.
METHODS:
In 50 patients operated on after September 2000, we monitored somatosensory evoked potentials and transcranially elicited epidural (D-wave) and muscle motor evoked potentials (INM group). The historical control group consisted of 50 patients selected from among 301 patients who underwent intramedullary spinal cord tumor surgery, previously operated on by the same team without INM. Matching by preoperative neurological status (McCormick scale), histological findings, tumor location, and extent of removal were blind to outcome. A more than 50% somatosensory evoked potential amplitude decrement influenced only myelotomy. Muscle motor evoked potential disappearance modified surgery, but more than 50% D-wave amplitude decrement was the major indication to stop surgery. The postoperative to preoperative McCormick grade variation at discharge and at a follow-up of at least 3 months was compared between the two groups (Student's t tests).
RESULTS:
Follow-up McCormick grade variation in the INM group (mean, +0.28) was significantly better (P = 0.0016) than that of the historical control group (mean, –0.16). At discharge, there was a trend (P = 0.1224) toward better McCormick grade variation in the INM group (mean, –0.26) than in the historical control group (mean, –0.5).
CONCLUSION:
The applied motor evoked potential methods seem to improve long-term motor outcome significantly. Early motor outcome is similar because of transient motor deficits in the INM group, which can be predicted at the end of surgery by the neurophysiological profile of patients.

Abstract
PURPOSE To determine survival and changes in neurologic function and Karnofsky performance status (KPS) in a series of patients treated for low-grade astrocytoma of the spinal cord during the past two decades. METHODS This study consisted of 14 patients with pathologically confirmed low-grade astrocytoma of the spinal cord who were treated between 1980 and 2003. All patients underwent decompressive laminectomy followed by biopsy (n = 7), subtotal resection (n = 6), or gross total resection (n = 1). Ten patients underwent postoperative radiotherapy (median total dose 50 Gy in 28 fractions). The overall survival, progression-free survival, and changes in neurologic function and KPS were measured. RESULTS The overall survival rate at 5, 10, and 20 years was 100%, 75%, and 60%, respectively. The progression-free survival rate at 5, 10, and 20 years was 93%, 80%, and 60%, respectively. Neither overall survival nor progression-free survival was clearly correlated with any patient, tumor, or treatment factors. Neurologic function and KPS worsened after surgery in 8 (57%) of 14 and 9 (69%) of 13 patients, respectively. At a mean follow-up of 10.2 years, neurologic function had stabilized or improved in 8 (73%) of 11 remaining patients, but the KPS had worsened in 5 (50%) of 10. Most patients who were employed before surgery were working at last follow-up. CONCLUSION Patients who undergo gross total resection of their tumor may be followed closely. Patients who undergo limited resection should continue to receive postoperative RT (50.4 Gy in 1.8-Gy fractions). The functional measures should be routinely evaluated to appreciate the treatment outcomes.

Abstract
The authors report a 12-year-old girl who presented with a 2-year progressive painless thoracic scoliosis. Her previous development had been normal with no significant past history of illness. MRI revealed a thoracic ganglioneuroma, which was confirmed by surgical pathology. Ganglioneuroma might cause progressive spinal deformity mimicking adolescent idiopathic scoliosis. A careful preoperative survey is mandatory for patients diagnosed with scoliosis with a rigid or rapidly progressive curve. The authors recommend a combination of neurosurgery and orthopedic spine surgery to treat this condition.

Abstract
OBJECT Intramedullary spinal cord tumors (IMSCTs) in the older-age adult population pose complex management issues regarding the extent of resection and functional outcome, especially in terms of quality of life. Historically, IMSCTs in the older adult population were treated with irradiation alone because it was assumed that functional recovery would be poor. The authors examined their IMSCT database and report the first large series of IMSCTs in patients older than 50 years of age. METHODS In this retrospective clinical and chart review there were 30 cases meeting inclusion criteria drawn from databases at three different institutions. A modified McCormick Scale was used to assess functional levels in all 30 patients pre- and postoperatively. The mean age of patients in this cohort was 59.8 years (range 50-78 years), and the mean follow-up period was 10.6 years (range 2-16 years). Ependymoma was the most common tumor (83%), and 55% were located in the thoracic spine. The most common presenting symptom was sensory dysesthesia, with rare motor loss. The prodromal period to treatment was 19.4 months. Based on the McCormick Scale score at last follow-up examination 67% of patients were clinically functionally the same, 9% were worse, and 24% were improved after surgery. There were two deaths due tumor progression (both malignant tumors) and one recurrence (anaplastic astrocytoma). All three patients in whom malignant astrocytomas were diagnosed underwent postoperative radiation therapy. CONCLUSIONS In the population of patients older than age 50 years, thoracic ependymomas are the most common IMSCTs that present characteristically with sensory symptoms. The longer prodromal period in the older adult population may reflect the fact that their diagnosis and workup is inadequate. There was no significant increase in the length of stay in the neurosurgical ward. The authors recommend motor evoked potential-guided aggressive microsurgical resection, because the long-term outcome of benign lesions is excellent (good functional recovery and no tumor recurrence).
