Predictive Factors of Long-Term Neurologic Outcome and Progression-Free Survival in Intramedullary Spinal Cord Tumors: A 10-year Single-Center Cohort Study and Review of the Literature. World Neurosurg 2024; 187:e94-e106.

Abstract
BACKGROUND Intramedullary spinal cord tumors (IMSCTs) are a rare subgroup of neoplasms, encompassing both benign, slow-growing masses, and malignant lesions; radical surgical excision represents the cornerstone of treatment for such pathologies regardless of histopathology, which, on the other hand, is a known predictor of survival and neurologic outcome postsurgery. The present study aims to investigate the relevance of other factors in predicting survival and long-term functional outcomes. METHODS We conducted a review of current literature on functional outcomes of IMSCTs, as well as a 10-years prospective analysis of a wide cohort of patients with diagnosis of IMSCTs who underwent surgical resection at our institution. RESULTS Our series encompasses 60 patients with IMSCTS, among which 36 ependymomas, 6 cavernous angiomas, 5 hemangioblastomas, 6 WHO Grade I-IV astrocytomas, 3 intramedullary spinal metastases and 4 miscellaneous tumors. GTR was achieved in 76,67% of patients, with high preoperative McCormick grade, syringomyelia and changes at neurophysiologic monitoring being the strongest predictors at multivariate analysis (P = 0.0027, P = 0.0017 and P = 0.001 respectively). CONCLUSIONS Consistently with literature, preoperative neurologic function is the most important factor predicting long-term functional outcome (0.17, CI 0.069-0.57 with P = 0.0018), advocating for early surgery in the management of IMSCTs, whereas late complications such as myelopathy and neuropathic pain were present regardless of preoperative function.

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
Introduction Intramedullary spinal cord tumors (IMSCTs) are rare but clinically significant entities that may cause severe neurological decline with progressive pain and motor or sensory deterioration. Beyond the beneficial effects of surgical treatment and the long-term progression-free survival, neurological deficits may still persist after surgery, and information about the long-term patients' health-related quality of life (QoL) is still lacking. In this study, we investigate the patients' health perception 15 years after the surgery in an overall patients' wellbeing framework. Methods Patients surgically treated for IMSCT over a period from 1996 to 2011 were selected. After a mean of 15 years from the surgery, patient's self-administered questionnaire on disability, pain, sleep quality, and QoL was collected and neurological postoperative evaluation at the chronic stage was reexamined. Results Neurological deficits are reported in half of the patients in the postoperative chronic phase. After 15 years of surgery, half of the patients still report mild or severe disability grades associated with significantly higher pain and poor sleep and QoL. In accordance, the neurological condition measured at the chronic stage is significantly related not only to disease-specific symptoms (i.e., pain) but even to sleep quality complaints and poor QoL, measured at 15 years follow-up. Conclusions Health-related QoL is an important secondary outcome in patients. Although the progression-free survival, worse postoperative neurological conditions could predict long-term sequelae reflecting patients' poor health perception. It suggests the importance of preserving patients' functional status and globally evaluating patients' wellbeing to handle disease-specific symptoms but even more general aspects of QoL.

Abstract
OBJECTIVE The established treatment of intramedullary spinal cord ependymomas (ISCEs) is resection. Surgical series reporting treatment results often lack homogeneity, as these are collected over long time spans and their analysis is plagued by surgical learning curves and inconsistent use of intraoperative neurophysiological monitoring (IONM). The authors report the oncological and functional long-term outcomes in a modern series of 100 consecutive ISCEs that were resected between 2000 and 2015 by a surgically experienced team that consistently utilized IONM. METHODS In this retrospective study, the authors tailored surgical strategy and multimodal IONM, including somatosensory evoked potentials, muscle motor evoked potentials (mMEPs), and D-waves, with the aim of gross-total resection (GTR). Preservation of the D-wave was the primary objective, and preservation of mMEPs was the second functional objective. Functional status was evaluated using the modified McCormick Scale (MMS) preoperatively, postoperatively, and at follow-up. RESULTS Preoperatively, 89 patients were functionally independent (MMS grade I or II). A GTR was achieved in 89 patients, 10 patients had a stable residual, and 1 patient underwent reoperation for tumor progression. At a mean follow-up of 65.4 months, 82 patients were functionally independent, and 11 lost their functional independence after surgery (MMS grades III-V). Muscle MEP loss predicted short-term postoperative worsening (p < 0.0001) only, while the strongest predictors of a good functional long-term outcome were lower preoperative MMS grades (p < 0.0001) and D-wave preservation. D-wave monitorability was 67%; it was higher with lower preoperative MMS grades and predicted a better recovery (p = 0.01). CONCLUSIONS In this large series of ISCEs, a high rate of GTR and long-term favorable functional outcome were achieved. Short- and long-term functional outcomes were best reflected by mMEPs and D-wave monitoring, respectively.

Abstract
This is a retrospective study. The aim of this study was to determine the indicators of neurological outcome after surgery in patients with intramedullary spinal ependymomas by using magnetic resonance imaging (MRI).A total of 106 consecutive patients (mean age: 42.4 ± 1.3 years; 52.8% male) diagnosed with intramedullary spinal ependymomas were retrospectively recruited. All patients underwent spine MRI and subsequent surgical resection for the spinal tumors. Data regarding clinical symptoms and pathological grades of tumors were collected from clinical records. The McCormick score was used for grading patients' neurological status before and after surgery at 12 months. Good outcome was defined as stable McCormick score (McC) score (no change of McC score between preoperation and post-operation at 12 months) or improvement in McC score (post-operative McC score at 12 months < preoperative McC score). Poor outcome was determined when there was an increase in McC score at 12 months after surgery. The MRI characteristics of spinal ependymomas between patients with good and poor neurological outcomes were compared. Logistic regression was performed to assess the association between MRI characteristics of tumors and post-operative neurological outcomes.Patients with poor neurological outcomes had larger longitudinal length (4.7 ± 0.5 vs 3.3 ± 0.2, P = .004) and higher enhancement signal-to-noise-ratio (SNR) (102.4 ± 12.3 vs 72.8 ± 4.6, P = .022) than those with good neurological outcomes. After adjusting for confounding factors, longitudinal length (OR, 0.768; 95% CI, 0.604-0.976; P = .031) and enhancement SNR (OR, 0.988; 95% CI, 0.978-0.999; P = .026) of spinal ependymomas were significantly associated with poor neurological prognosis.The longitudinal length of tumor and enhancement SNR on T1-weighted images are independently associated with neurological outcome after surgery.

Abstract
BACKGROUND Сervicomedullary ependymoma (CME) is a rare tumor of the central nervous system. The CME treatment strategy is insufficiently represented in the literature and is a complex task for neurosurgeons. OBSERVATIONS The authors describe an infrequent case of a large multisegmental CME that extended from the medulla oblongata to the cervical spinal cord at the level of the sixth cervical vertebra in a 21-year-old female. Neurological disorders presented with headache, dysphagia, hypophonia, and weakness in the limbs. Subtotal removal of the tumor was performed according to intraoperative neurophysiological monitoring (IONM) results. A wait-and-see approach with patient follow-up was chosen. LESSONS Total tumor removal of the CME is the most important favorable prognostic factor. Subtotal resection can be considered if the borders of the tumor are unclear and the result of IONM is unfavorable. The role of postoperative radiation therapy in the case of subtotal removal of the tumor remains controversial.

Abstract
Artificial intelligence is poised to influence various aspects of patient care, and neurosurgery is one of the most uprising fields where machine learning is being applied to provide surgeons with greater insight about the pathophysiology and prognosis of neurological conditions. This chapter provides a guide for clinicians on relevant aspects of machine learning and reviews selected application of these methods in intramedullary spinal cord tumors. The potential areas of application of machine learning extend far beyond the analyses of clinical data to include several areas of artificial intelligence, such as genomics and computer vision. Integration of various sources of data and application of advanced analytical approaches could improve risk assessment for intramedullary tumors.

Abstract
The brainstem is a less-common location for ependymomas than the spinal cord where they are the most common adult intramedullary tumor.1-18 In this first video case report in the peer-reviewed literature, we demonstrate microsurgical resection of a medulla oblongata ependymoma. There are several case reports of medulla oblongata ependymomas1,3,5,6,13 and a few series of spinal cord ependymomas that included cases of ependymomas of the cervicomedullary junction.9,10 The goal of surgery was to stabilize the preoperative neurological function; favorable outcome is achieved in patients with good preoperative statuses and well-defined tumor boundaries.9 Although gross total resection (GTR) provides the best overall outcome, it is most effective for classic grade II tumors, but not grade I (myxopapillary) and ependymomas, which have a lower GTR rate.14,15 A 55-yr-old patient developed 4-extremity weakness and dysphagia. Pre-/postcontrast magnetic resonance imaging (MRI) revealed centrally located brainstem lesion situated at the lower half of the medulla oblongata. Surgery, performed by the senior author, was performed in the prone position with a small suboccipital craniectomy and C1 posterior arch removal, followed by pia opening and posterior midline myelotomy. Tumor was debulked, dissected from the white matter, and resected. Histology revealed ependymoma (World Health Organization grade II). Postoperative pre-/postcontrast MRI revealed total resection. The patient's neurological deficit completely resolved postoperatively. Written consent was obtained from the patient.

Abstract
INTRODUCTION The posterior fossa is the most common intracranial location for pediatric ependymoma. While ependymoma usually arises from the ventricular lining of the fourth ventricle as a solid mass, it rarely originates from the brainstem. Grade II ependymomas also infrequently appear as a cavitary ring-enhancing lesion. CASE PRESENTATION We describe a case of a 6-year-old boy with an ependymoma arising within the medulla with imaging features of a thick-walled rim-enhancing cavitary lesion. A stereotactic biopsy was obtained which confirmed a grade II ependymoma. The patient received focal proton beam radiation therapy and is doing well with no concerns for disease progression at 28 months after diagnosis. CONCLUSION Posterior fossa ependymomas typically arise from ependymal cells within the fourth ventricle or foramina of Luschka. They rarely invade or arise within the brainstem parenchyma. Our case had atypical imaging findings in addition to the atypical tumor location. The lesion was described as a thick-walled rim-enhancing focal cystic necrotic lesion centered within the medulla with surrounding nonenhancing expansile infiltrative changes. Ring-enhancing lesions can be seen in patients with anaplastic ependymoma, but is not commonly reported in grade II ependymomas. In summary, this report highlights a unique case of a posterior fossa ependymoma in a pediatric patient arising in an atypical brainstem location as well as having unique imaging features.

Abstract
Ependymomas are the most common adult intramedullary spinal tumors.1 Although uncommon in the brainstem, ependymomas make up a large proportion of tumors of this location.2-8 We present an operative video case report of an intrinsic ependymoma at the cervicomedullary junction. The purpose of this report is to present the clinical picture, operative setup, and surgical technique involved in resection of an intramedullary tumor of this region. For best outcome for intramedullary ependymomas, the goal should be gross total resection.1,9,10 These tumors have a relatively distinct plane between tumor and normal parenchyma, making a gross total resection more probable than cases of infiltrative intramedullary astrocytomas.11 Despite this, significant morbidity can be associated with treatment.1 Proper microsurgical technique with use of operative adjuncts can maximize resection while minimizing neurologic injury to optimize outcomes in patients. We present the case of a 42-year-old man presenting with neck and shoulder pain, upper extremity paresthesias, and gait instability. Magnetic resonance imaging of the neuroaxis revealed a heterogeneously enhancing expansile lesion in the lower medulla and multiple lesions in the thecal sac, representing drop metastases. Due to symptoms and mass effect from the lesion, the patient underwent a suboccipital craniotomy for tumor resection. We highlight operative techniques in our case, including use of neurophysiologic monitoring, intraoperative ultrasound, ultrasonic aspirator, and dissection with microcottonoid pledgets and bimanual technique. Pathology revealed a World Health Organization grade II ependymoma. Postoperative magnetic resonance imaging revealed a small amount of residual. He underwent full craniospinal proton beam therapy with boost to the residual and metastases with good outcome. Patient provided consent for this report.

Abstract
OBJECTIVE To identify the risk factors for recurrence of World Health Organization (WHO) grade Ⅱ ependymomas of spinal cord in adults after microsurgical resections. PATIENTS AND METHODS A total of 118 adult patients diagnosed with WHO grade Ⅱ ependymomas of spinal cord at west china hospital from January 2010 to December 2016 were reviewed retrospectively. To identify the risk factors for recurrence, we performed univariate analyses and multivariate logistic regression analyses successively. RESULTS Twelve patients had a recurrence with a median recurrence time of 30 months [inter-quartile range (IQR) 23.5-75.5 months]. Univariate analysis showed that age (p = 0.030), STR (p < 0.001), index of Ki-67 (p = 0.004), and Vimentin (+, p = 0.004) were associated with postoperative recurrence of ependymomas of spinal cord in adults, while univariate analysis showed that only STR [odds ratio (OR) = 18.838, 95 % confidence interval (CI): 3.068-115.673; p = 0.002], index of Ki-67 (OR = 1.381, 95 % CI: 1.021-1.868; p = 0.036), Vimentin (+; OR = 6.706, 95 % CI: 1.218-36.928; p = 0.029) were independent risk factors for recurrence. CONCLUSIONS The recurrence rate of WHO grade Ⅱ ependymomas of spinal cord in adults was about 13.6 %. Subtotal resection is a critical risk factor for recurrence. A high index of Ki-67 is another independent risk factor for recurrence. Positive Vimentin may also play a role in this process. GTR is very important to prevent recurrence after operation if it is safe to conduct. In cases with higher index Ki-67 and Vimentin (+), close follow-ups are necessary.

Feasibility of Neurorehabilitation Using a Hybrid Assistive Limb for Patients Who Underwent Spine Surgery. Appl Bionics Biomech 2018; 2018:7435746. [PMID: 30116296 PMCID: PMC6079604 DOI: 10.1155/2018/7435746] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2018] [Revised: 05/21/2018] [Accepted: 06/19/2018] [Indexed: 12/18/2022] Open
Abstract
Recent studies of robotic rehabilitation have demonstrated its efficacy for neurological disorders. However, few studies have used the Hybrid Assistive Limb (HAL) during the early postoperative stage of spine disorders. We aimed to evaluate the safety and efficacy of HAL treatment during the early postoperative period for spine disorder patients. We retrospectively identified patients who underwent spine surgery and who could complete HAL treatment. We evaluated the 10-m walking test (10MWT), the modified Gait Abnormality Rating Scale (GARS-M), Barthel Index (BI), and the walking index for spinal cord injury II (WISCI II) score results before and after robotic rehabilitation. Clinical outcomes were compared after treatment. We included nine patients with various spine problems. After HAL treatment, the speed during the 10MWT significantly improved from 64.1 ± 16.0 to 74.8 ± 10.8 m/min, and the walking cadence decreased from 102.7 ± 17.6 to 92.7 ± 10.9 steps/min. The BI score also improved from 83.3 ± 16.0 to 95.6 ± 5.8, and the WISCI II score improved from 19.7 ± 0.5 to 20.0 ± 0.0. Furthermore, the total GARS-M score improved from 6.0 ± 5.7 to 2.3 ± 3.3. The maximum angles of the trunk swing were improved from 2.2 ± 1.9 to 1.2 ± 0.9 degrees. Neurorehabilitation therapy using HAL for spinal surgery patients was considered feasible following spine surgery.

[PMID: 28717891 DOI: 10.1007/s10143-017-0879-z] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2017] [Revised: 06/24/2017] [Accepted: 07/03/2017] [Indexed: 11/25/2022]
Abstract
Intramedullary spinal cord tumors (IMSCTs) are relatively infrequent lesions with ependymomas and astrocytomas representing the most common types. Microsurgical resection is established as the treatment of choice for these challenging lesions. We reviewed the surgical outcome of 29 cases operated for IMSCTs by the same surgeon between 2009 and 2015. The median follow-up period was 31 months, and all patients were followed up at least for 1 year. Among these 29 cases, 5 patients were previously operated for partial resection elsewhere. Age ranged from 9 to 62 years with a median of 39 years. All patients were symptomatic before surgery. The most common pathology was ependymoma (16 cases), and the most common tumor location was the cervical spine (18 cases). Gross total resection was achieved in 20 out of 29 cases (68.9%). Tumors were totally excised in all cases of ependymoma except in two patients; one was previously operated and irradiated and the second had an extensive anaplastic ependymoma. Sixteen cases experienced immediate post-operative worsening which was temporary in all but one case. At 1-year follow up, 23 patients (79.3%) maintained their pre-operative McCormick grade, 5 patients (17.2%) had a better grade, and 1 patient (3.5%) deteriorated. Surgery still represents the mainstay in the management of IMSCT. Gross total resection can be achieved safely in many cases especially in the presence of an identifiable plane of cleavage between the tumor and the normal spinal cord.

Montano N, Papacci F, Trevisi G, Fernandez E. Factors affecting functional outcome in patients with intramedullary spinal cord tumors: results from a literature analysis. Acta Neurol Belg 2017; 117:277-282. [PMID: 27475420 DOI: 10.1007/s13760-016-0684-4] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2016] [Accepted: 07/26/2016] [Indexed: 12/31/2022]
Abstract
Recently, great advances have been made in the surgical treatment of intramedullary spinal cord tumors (IMSCTs). Many articles have been published; but looking at the literature of the last 5 years, there are only descriptive reviews and no works in which a literature statistical analysis was performed. Here, we analyzed the literature to identify potential prognosticators of good functional outcome in IMSCT patients. To level out the selected studies, we stratified patients' neurological status as independent (ambulation possible without caregiver assistance) or disabled (cannot ambulate or can only ambulate with caregiver assistance). 18 out of 125 articles were included in the analysis (691 patients). A significant higher percentage of gross total resection (GTR) in ependymomas, hemangioblastomas and cavernomas compared to the astrocytomas (particularly high-grade gliomas) was observed. We found a strong correlation between a good pre-operative neurological function and a good post-operative and at follow-up (FU) neurological status and between GTR and a good post-operative and at FU neurological status. A significant better outcome was found in ependymomas, hemangioblastomas and cavernomas compared to astrocytomas. Our analysis suggests that an early surgery could be reasonable in IMSCTs, because a good pre-operative neurological function is a strong predictor of good neurological outcome. In patients with high-grade gliomas, there is no indication to attempt a GTR due to the infiltrative growth pattern of this tumor that leads to a higher surgical morbidity. Although not innovative, the evidences of our literature statistical analysis strengthen the results from previous surgical series and descriptive reviews.
