Subependymal giant cell astrocytoma: diagnosis, screening, and treatment. NLM The analysis of outcome of subependymal giant cell astrocytoma surgery may help characterize the patients who may benefit from pharmacotherapy. In a phase 1–2, open-label study in 28 patients with evidence of serial subependymal giant cell astrocytoma growth, the mTOR inhibitor everolimus (Afinitor, Novartis, East Hanover, NJ) was associated with a reduction in SEGA volume and improved quality of life 3). [1] It is most commonly associated with tuberous sclerosis complex (TSC).Although it is a low-grade tumor, its location can potentially obstruct the ventricles and lead to hydrocephalus. Arroyo et al. NIH SEGA vs. SGTC: SEGA is most commonly known as the brain neoplasm associated with TSC (18, 24, 28).Historically, these tumors were considered to be astrocytomas. Roth J, Roach ES, Bartels U, Jóźwiak S, Koenig MK, Weiner HL, Franz DN, Wang HZ. Learn more about the treatment of newly diagnosed and recurrent astrocytoma in this expert-reviewed summary. Conclusions: Everolimus can effectively reduce tumor size, decrease cerebrospinal fluid protein, and allow successful ventriculoperitoneal shunt placement without the need for surgical resection of a symptomatic SEGA. Accordingly, current views in open surgical treatment, medical therapy, endoscopic tumor removal, and new trends (such as laser interstitial thermal therapy) are discussed.  |  Keywords: Epub 2010 May 21.

About subependymal giant cell astrocytoma (SEGA) tumors and tuberous sclerosis complex (TSC) Affecting approximately 1 million people worldwide, tuberous sclerosis complex (TSC) is a rare genetic disease that can affect many vital organs, and causes symptoms and resulting disorders such as noncancerous tumors, epilepsy, autism, cognitive impairment, and psychiatric disorders.

Childs Nerv Syst. present a seven-year-old boy with a large, symptomatic SEGA which was treated acutely with everolimus. If symptoms arise, or if serial neuroimaging demonstrates tumor growth, neurosurgical intervention is recommended. Everolimus treatment resulted in rapid reduction in tumor size, symptomatic improvement, and decrease in cerebrospinal fluid protein. An astrocytoma is a brain tumor that starts in cells called astrocytes, star-shaped cells that make up the glue-like or supportive tissue of the brain.

Most importantly, mTOR inhibitor therapy appears to be relatively safe. April 2012 approved for the treatment of adults with renal angiomyolipoma and tuberous sclerosis complex (TSC) not requiring immediate surgery. Recent reports of successful nonsurgical treatment of SEGAs are promising, and it is hoped that further specifics on dosing, duration, and long-term outcome will help patients and physicians to make informed therapeutic choices.Present treatment recommendations for SEGAs include routine surveillance neuroimaging and close clinical follow-up, paying particular attention to signs and symptoms of acute hydrocephalus.
