Background:Although primary spinal cord tumors (PSCTs) comprise a minority of primary central nervous system tumors, they often impose a great deal of morbidity on their victims. Few epidemiologic studies have addressed PSCTs in Iran.Materials and Methods:We analyzed the demographic/clinical features of all primary intraspinal tumors (with a specific focus on primary intradural spinal cord tumors) identified between 1992 and 2004 in three of the major related hospitals in Isfahan, Iran. We also tracked the malignant cases until 2012.Results:102 patients with primary intraspinal tumors were found; 82 tumors were Intradural (36 intramedullary and 46 extramedullary) and 20 extradural. The principal intradural histological subtypes were nerve sheath tumor (33%), ependymoma (22%), astrocytoma (16%), and meningioma (15%). 20 (19%) of the tumors were malignant. Local pain (43%) and motor disabilities (36%) were the most common first-presenting symptoms in the patients. Male-to-female ratio was significant only in ependymoma (male:female ratio = 3.6, P < 0.05). The mean age in meningioma (57 years, standard error [SE]: 15.7) was significantly higher than other types (one-way ANOVA, P < 0.05).Conclusion:Our results reflect analogous frequency of distribution for PSCTs compared with most of the previous counterpart studies worldwide. The only notable exception was the comparatively fewer frequency of spinal cord meningioma in our study.
Pathologic and Epidemiologic Findings of Intramedullary Spinal Cord Tumors
Neurosurgery Clinics of North America, 2006
Understanding the significance of the histologic type and grade is critical in the diagnosis and treatment of spinal cord tumors. Spinal tumors can be divided into three major groups based on their location: intramedullary, intradural extramedullary, and extradural [1]. Neuroepithelial tumors, particularly gliomas, constitute almost all intramedullary tumors. Intradural extramedullary lesions include meningiomas derived from meningothelial cells lining the surface of the cord. Extradural lesions are typically nonneuroepithelial, and most such tumors are metastases or peripheral nerve sheath tumors like schwannomas. Occasionally, an extradural tumor extends through the intervertebral foramina, lying partially within and partially outside the spinal canal (dumbbell or hourglass tumors).
Primary spinal cord tumors: review of 678 surgically treated patients in Japan. A multicenter study
European Spine Journal, 2012
Purpose To clarify the relative frequency of various histopathological primary spinal cord tumors and their features in Japanese people and to compare this data with other reports. Methods Primary spinal cord tumor surgical cases from 2000 to 2009, which were registered in our affiliated hospital database were collected. We examined age at surgery, sex, anatomical location, vertebral level of the tumor, and pathological diagnosis in each case. Results Of the 678 patients in our study, 377 patients (55.6 %) were males and 301 patients (44.4 %) were females (male/female ratio 1.25). The mean age at surgery was 52.4 years. Of these tumors, 123 cases (18.1 %) were intramedullary, 371 cases (54.7 %) were intradural extramedullary, 28 cases (4.1 %) were epidural, and 155 cases (22.9 %) were dumbbell tumors. The pathological diagnoses included 388 schwannomas (57.2 %), 79 meningiomas (11.6 %), 54 ependymomas (8.0 %), 27 hemangiomas (4.0 %), 23 hemangioblastomas (3.4 %), 23 neurofibromas (3.4 %), and 9 astrocytomas (1.3 %). The male/female ratios for schwannomas, meningiomas, ependymomas,
Intramedullary spinal cord tumors: A retrospective multicentric study
Journal of Craniovertebral Junction and Spine, 2021
Context: Intramedullary tumors are neoformations taking part on the spinal cord, and they are a rare pathology. Due to the rarity of such lesions, clinical studies take years to ensure a decent feedback with a significant number of cases. Design: Our study is retrospective and descriptive. Participants: We share a Tunisian multicentric experience of 27 years through a retrospective study of 120 cases of spinal cord tumors that have been operated in six different centers. Outcome Measures: The clinical, radiological, and histological findings have been analyzed along with postoperative results and tumoral progression so that we could conclude to some factors of prognosis concerning the management of these tumors. Results: The mean age of our patients is 33.84 years. We had 57 males and 63 females. The most frequent revealing symptom was motor trouble presented as frequent as 77.5% of the patients. Glial tumors were represented in 81 of the cases (67.5%) and nonglial by 39 cases (32.5%). Glial tumors we found were essentially 39 ependymomas and 35 astrocytomas. Surgical resection is key in the management of these lesions; the quality of tumoral resection was a significant factor of disease progression as subtotal resection is correlated to more important progression than total one. Conclusion: We conclude this work with some statements. In terms of functional results, age is not a significant factor. Presurgical functional state, the histological type, and the extent of surgical resection are the important factors.

Aim The incidence of spinal cord tumors (SCTs) in a population considering sex, age, histopathology, and emplacement position of tumors is different between various regions. Therefore, the present study aimed to evaluate the frequency of various SCTs in surgically treated patients in a reference spinal surgery center in Shiraz, Iran. Method Documented information related to 109 SCT patients surgically treated was collected from the archive of Shahid Chamran Hospital (the reference center of spinal cord surgery in the south of Iran) in Shiraz from 2012 to 2022. This information includes demographics, medical history, histology, and position of SCTs within the spinal cord. Result The population of patients included 65 men and 44 women, with a mean age of 44.7 years old. Most patients (26 cases) were in the age group of 50–59 years. Neurological function in most patients (51 cases) was equivalent to level D of the ASIA impairment scale (AIS), and the most common complaints of patients ...
Descriptive epidemiology of primary spinal cord tumors
Journal of Neuro-Oncology, 2008
Object There is little population-based data available on primary spinal cord tumors. Many of the existing statistics are not current or were obtained from surgical series. Historically, population-based data were collected only for malignant tumors, and only recently have data begun to be collected on non-malignant tumors. The objective of this study was to estimate the incidence of both non-malignant and malignant primary spinal cord tumors and to estimate the survival rates for primary malignant spinal cord tumors. Methods Incidence of spinal cord tumors was estimated from cases diagnosed between 1998 and 2002 in 16 CBTRUS collaborating state cancer registries. Ageadjusted rates were generated using SAS (8.2) and standardized to the 2000 US standard population. SEER*Stat 6.1.4 software was used to estimate relative survival for malignant spinal cord tumors for cases diagnosed between 1975 and 2002 in nine SEER regions. Conclusions Of the spinal cord tumors identified (CBTRUS; n = 3,226), 69% were non-malignant. The most common histologic types were meningiomas (29%), nerve sheath tumors (24%), and ependymomas (23%). The overall incidence of spinal cord tumors was 0.74 per 100,000 person-years, with an incidence of 0.77/100,000 in females and 0.70/100,000 in males. The incidence rate was lowest in children (0.26) and peaked in the 75-84 year age group (1.80). Rates were higher in non-Hispanic whites (0.79) than in Hispanics (0.61) or non-Hispanic blacks (0.45). The 1-, 5-, and 10-year survival rates following diagnosis of a primary malignant spinal cord tumor were 85%, 71%, and 64%, respectively (SEER; n = 1,220).
Clinical profile, management and surgical outcome of spinal cord tumors
International Surgery Journal
Background: Spinal cord tumors can result in dramatic neurological and functional disabilities in the patients. We aimed to know the incidence of different types of spinal tumors and correlation between clinical presentation and pathological findings and compare outcomes of these tumors postoperatively.Methods: A total of 50 patients were included in the study group. After a thorough clinical evaluation, patients were subjected to a magnetic resonance imaging (MRI) and then surgery. They were described on the basis of age, sex, location of the tumor, type of the tumor, symptoms, histopathological type, surgical resection and complications.Results: Study included 29 males and 21 females and their age ranged from 5 years to 70 years. Out of the 50 patients, 39 had intradural and 11 had extradural spinal tumors. Amongst the 39 intradural tumors, 27 were extramedullary and 12 were intramedullary in location. A predilection towards the thoracic region (44%) was seen followed by the cervi...

Purpose To study the demography, incidence, symptoms, histopathology, postoperative complications and recovery in operated patients of spinal tumor. Overview of Literature Primary spinal cord tumors (SCT) are an uncommon entity. According to their location, spinal tumors are conveniently classified as extradural (ED) and intradural (ID), although some can be both inside and outside the dura. ID tumors can be intradural extramedullary (IDEM) or intramedullary SCT (IMSCT). Methods This is a retrospective study of 122 patients with spinal tumors who were surgically treated at the department of neurosurgery from 2014 to 2019 over a period of 5 years. Study Design This is a retrospective study. Results Out of 122 patients, there were 19 patients with ED tumor, 73 had IDEM, and 30 had IMSCT. As many as 73 patients were males and the rest of the 49 patients were females. Mean age at time of surgery was 40.79 years. The thoracic region of spinal canal was most frequently involved (64; 52.4%...

Background: Intradural extramedullary spinal cord tumors (IESCT) account for approximately two-thirds of largely benign intraspinal neoplasms. They occasionally present with acute neurological deterioration warranting emergent surgical intervention. Methods: Here, we reviewed a series of 31 patients with intradural extramedullary spinal tumors who underwent surgery from 2012 to 2019. Patients averaged 50.8 years of age, and there were 16 males and 15 females. Patients were followed for a minimum of 1 year. Multiple clinical outcome variables were studied (e.g., Karnofsky Performance Score [KPS], visual analog scale (VAS), and Frankel grade). Results: The majority of IESCT tumors were found in the thoracic spine 18 (58.06%) followed by the lumbar 8 (25.80%), cervical 1 (3.22%), and combined junctional tumors 4 (12.90%) (cervicothoracic-02 and thoracolumbar-02). Histopathological diagnoses included schwannomas-16 (51.61%), meningiomas-11 (35.48%), lipomas-2 (6.45%), hemangiomas-1 (3.2...

2011
Objective: To assess the spectrum of clinical, radiological and histological features of patients with intradural spinal tumors. Materials and methods: This descriptive study was carried out in Department of Neurosurgery Lady Reading Hospital Peshawar, from April 2003 to March 2009. Medical records of patients with spinal tumors were revieqwed and patients operated for intradural spinal tumors were identified. A total of 312 patients, out of 525 cases of spinal tumors, with different intradural spinal tumors were considered in this study. Their clinical features, radiological reports, peroperative findings and histological reports were analyzed in different aspects. Results: There were total of 312 patients with age range from 2 years to 74 years, with median age of 38 years. Out of these 187 were males and 125 were female, overall male to female ratio of 1.5:1. Backache, leg weakness, parasthesia and poor sphincters were the main clinical features. MRI spine (274 cases) was the main diagnostic tool along with plain X-rays and X-ray myelography in limited cases (35 cases). CT myelogram was done only in 3 cases. The common site of involvement was dorsal spine followed by lumber and cervical spines respectively in
