Email: [email protected] ABSTRACT Introduction: Tumors of the central nervous system (CNS) are the second most frequent malignancy of childhood and the most common solid tumor in this age group. CNS tumors represent approximately 17% of all malignancies in the pediatric age range, including adolescents. Glial neoplasms in children account for up to 60% of supratentorial intraaxial tumors. Their histological distribution and prognostic features differ from that of adults. Aims and Objectives: To study clinical and pathological characteristics, and to analyze the outcome using the Engel’s classification for seizures, Karnofsky’s score during the available follow‑up period of minimum 1 year following the surgical and adjuvant therapy of supratentorial intraaxial extraventricular primary pediatric (SIEPP) brain tumors in children equal or less than 18 years. Materials and Methods: The study design is a prospective study done in NIMS from October 2008 to January 2012. All the patients less than 18 years of age operated for SIEPP brain tumors proven histopathologically were included in the study. All the patients with recurrent or residual primary tumors or secondaries were excluded from the study. Post operative CT or magnetic resonance imaging (MRI) is done following surgery. -

A Case of Intramedullary Spinal Cord Astrocytoma Associated with Neurofibromatosis Type 1
KISEP J Korean Neurosurg Soc 36 : 69-71, 2004 Case Report A Case of Intramedullary Spinal Cord Astrocytoma Associated with Neurofibromatosis Type 1 Jae Taek Hong, M.D.,1 Sang Won Lee, M.D.,1 Byung Chul Son, M.D.,1 Moon Chan Kim, M.D.2 Department of Neurosurgery,1 St. Vincent Hospital, The Catholic University of Korea, Suwon, Korea Department of Neurosurgery,2 Kangnam St. Mary's Hospital, The Catholic University of Korea, Seoul, Korea The authors report a symptomatic intramedullary spinal cord astrocytoma in the thoracolumbar area associated with neurofibromatosis type 1 (NF-1). A 38-year-old woman presented with paraparesis. Magnetic resonance imaging revealed an intramedullary lesion within the lower thoracic spinal cord and conus medullaris, which was removed surgically. Pathological investigation showed anaplastic astrocytoma. This case confirms that the diagnosis criteria set by the National Institute of Health Consensus Development Conference can be useful to differentiate ependymoma from astrocytoma when making a preoperative diagnosis of intramedullary spinal cord tumor in patients of NF-1. KEY WORDS : Astrocytoma·Intramedullary cord tumor·Neurofibromatosis. Introduction eurofibromatosis type 1 (NF-1), also known as von N Recklinghausen's disease, is one of the most common autosomal dominant inherited disorders with an incidence of 1 in 3,000 individuals and is characterized by a predisposition to tumors of the nervous system5,6,12,16). Central nervous system lesions associated with NF-1 include optic nerve glioma and low-grade gliomas of the hypothalamus, cerebellum and brain stem6,10). Since the introduction of magnetic resonance(MR) imaging, Fig. 1. Photograph of the patient's back shows multiple subcutaneous incidental lesions with uncertain pathological characteristic nodules (black arrow) and a cafe-au-lait spot (white arrow), which have been a frequent finding in the brain and spinal cord of are typical of NF-1. -

Standard treatment only slightly improves patient survival. Therefore, new therapies are needed. Very few risk factors have been clearly identified but many epidemiological studies have reported a higher incidence in men than women with a sex ratio of 1:4. Based on these observations, it has been proposed that the neurosteroids and especially the estrogens found in higher concentrations in women’s brains could, in part, explain this difference. Estrogens can bind to nuclear or membrane receptors and potentially stimulate many different interconnected signaling pathways. The study of these receptors is even more complex since many isoforms are produced from each estrogen receptor encoding gene through alternative promoter usage or splicing, with each of them potentially having a specific role in the cell. The purpose of this review is to discuss recent data supporting the involvement of steroids during gliomagenesis and to focus on the potential neuroprotective role as well as the mechanisms of action of estrogens in gliomas. -

Information Sheet 4: High-Grade Glioma Brain Tumours and Treatment Options
Information Sheet 4: High-Grade Glioma brain tumours and treatment options This information document on high grade brain tumours simply provides a basis for discussion with the healthcare professionals with whom you are in contact. It should not in any way be used as a substitute for professional care. What is a Glioma? There are nearly 100 different types of brain tumours. Most primary brain tumours develop from the cells that support the nerve cells of the brain. These are called glial cells. So a tumour of glial cells is given the collective name of a glioma. About half of all primary brain tumours are gliomas. Low-grade or high-grade? Brain tumours are put into groups according to how fast they are likely to grow. There are four groups, called Grades 1–4. The cells are examined under a microscope, and the more normal they look, the more slowly the brain tumour is likely to develop and the lower the grade. The more abnormal the cells look, the more quickly the brain tumour is likely to grow and the higher the grade. You may have been told you have a benign tumour or a malignant tumour. Low-grade tumours are generally regarded as benign and high-grade as malignant. Malignant So, generally speaking, malignant means that: The tumour is relatively fast growing It may come back after surgery, even if completely removed It may spread to other parts of the brain or spinal cord It cannot just be treated with surgery and will need further treatments, such as radiotherapy or chemotherapy, to try to stop it from returning. -
