Can optic nerve gliomas be cured?
While these are serious tumors, they have a high cure rate. Nearly 75 percent of optic nerve gliomas, which may affect one or both eyes, occur in children younger than 10, with most younger than 5 years of age at the time of diagnosis.
Is an optic nerve glioma fatal?
Introduction: Adult malignant optic nerve gliomas are rare and rapidly fatal visual pathway tumours. They represent a clinical entity different from the more common childhood benign optic nerve gliomas, which are frequently associated with neurofibromatosis I.
What is the best treatment for NF1?
Neurofibromatosis type 1 (NF1) is a genetic condition in which benign tumors arise along nerves anywhere in the body. Treatment for these tumors most often includes surgery; it sometimes also includes chemotherapy, radiation therapy, or both.
Can optic nerve glioma spread?
Gliomas grow slowly but have the potential to spread into the surrounding tissues, including around the optic nerve, the chiasm, and into the adjacent brain. In most patients, with slow growth, there is stabilization of the vision. In about 40% of patients, however, continued growth may be seen.
What does optic nerve glioma look like?
Initial signs and symptoms of malignant gliomas include severe retro-orbital pain, unilateral or bilateral vision loss, and, typically, massive swelling and hemorrhage of the optic nerve head (although disc pallor may also be observed with posterior lesions).
Can optic nerve tumor be removed?
Results The most common primary tumour of the optic nerve is the benign glioma. This low-grade astrocytoma usually can be followed without intervention. Progression of visual symptoms and signs may necessitate either surgery to remove the tumour or radiation therapy.
Is optic glioma cancerous?
Optic nerve glioma is a rare kind of cancer that’s typically slow growing and found in children. It is rarely found in individuals over the age of 20. It has also been associated with the genetic disorder neurofibromatosis type 1, or NF1.
Is optic nerve glioma cancerous?
Optic nerve gliomas are benign (non-cancerous) brain tumors that grow on the nerves that carry vision from the eyes to the brain (the optic nerves). Optic nerve gliomas are found in approximately one in five children with NF1. These tumors commonly arise in young children and can affect their vision.
How do they remove a tumor from the optic nerve?
Surgery and radiation therapy are two possible ways of treating optic nerve glioma. Your doctor can determine which type of treatment is best for you. Surgery is not always an option. Surgery may be performed if doctors believe they can use it to completely remove the tumor.
What is the current treatment for optic nerve glioma?
Current treatment of optic nerve gliomas Although standard chemotherapy remains the mainstay of ONG treatment, newer molecularly targeted therapies such as mitogen-activated protein kinase kinase inhibitors and bevacizumab represent a promising new treatment modality, and clinical studies are ongoing.
How is neurofibromatosis type 1 treated in children?
In children with neurofibromatosis type 1 with an isolated optic nerve tumor, treatment choices at the time of diagnosis include: observation alone, surgery or chemotherapy. Radiotherapy is infrequently used due to concerns over long-term medical complications of such treatment, including the development of secondary tumors.
What is the prevalence of optic pathway glioma (OPG) in neurofibromatosis type 1 (NF1)?
1 Division of General Academic Pediatrics, Department of Pediatrics, Children’s Memorial Hospital, Feinberg School of Medicine, Northwestern University, Chicago, IL, USA. Optic pathway glioma (OPG), seen in 15% to 20% of individuals with neurofibromatosis type 1 (NF1), account for significant morbidity in young children with NF1.
Can optic gliomas affect the optic nerve?
They can affect the optic nerve, optic chiasm, optic tracts and radiations and can either be sporadic or associated with neurofibromatosis type one. Gliomas isolated to the optic nerve (ONG) represent a subgroup of optic pathway gliomas, and their treatment remains controversial.
