Abstract
Optic pathway gliomas (OPGs) are rare neoplasms in children with an unpredictable clinical course. There is significant controversy regarding the optimal management and outcome of these patients. Charts of all patients with OPG diagnosed and treated at Children's Cancer Hospital Egypt between July 2007 and July 2014 were retrospectively reviewed. We evaluated the roles of surgical, ophthalmologic, endocrinologic, neurologic, and treatment aspects of care. Sixty-five patients were included in this study, with a mean age of 5.3 years. OPGs were chiasmatic (n = 25), optic nerve (n = 18), hypothalamic (n = 7), and chiasmatic/hypothalamic (n = 7). Extensive involvement of the optic pathway was seen in an additional 8 patients. Twenty cases had neurofibromatosis type 1. Four cases underwent surgical debulking, and 28 were biopsied (16 open, 11 stereotactic, and 1 endoscopic). Nine of the 18 optic nerve tumors were managed by total excision. Twenty-four patients did not undergo any surgical intervention. Forty-five patients received chemotherapy. Histopathology revealed pilocytic (n = 20), pilomyxoid (n = 15), fibrillary astrocytoma (n = 4), and grade I papillary-glioneuronal tumor (n = 1). Nonrepresentative sample (n = 1). The 4-year...Continue Reading
