Subependymal Giant Cell Astrocytoma: The Molecular Landscape and Treatment Advances.

Simple Summary: Subependymal giant cell astrocytoma is a slow-growing brain tumor affecting children and young adults. Despite the characteristic molecular and clinical features, the severity of the disease varies from patient to patient, and, in addition, tumors in their early stages can be asymptomatic for a long time. Morbidity and mortality are due to the location of the tumor, which can obstruct the flow of cerebrospinal fluid, leading to progressive hydrocephalus and even death. The etiology and the response to treatment are still poorly understood due to the diversity of the background and the course of the disease. Therefore, this review aims to present and discuss the latest research on SEGA, its diagnosis, and treatment. Subependymal giant cell astrocytoma (SEGA) is most often found in patients with TSC (Tuberous Sclerosis Complex). Although it has been classified as a benign tumor, it may create a serious medical problem leading to grave consequences, including young patient demise. Surgery and chemotherapy belong to the gold standard of treatment. A broader pharmacological approach involves the ever-growing number of rapalogs and ATP-competitive inhibitors, as well as compounds targeting other kinases, such as dual PI3K/mTOR inhibitors and CK2 kinase inhibitors. Novel approaches may utilize noncoding RNA-based therapeutics and are extensively investigated to this end. The purpose of our review was to characterize SEGA and discuss the latest trends in the diagnosis and therapy of this disease. [ABSTRACT FROM AUTHOR]
