Overview
Surgery
- Surgery is the mainstay of treatment for subependymal giant cell astrocytoma.[1]
- Treatment of subependymal giant cell astrocytoma has been solely surgical because of a lack of responsiveness to other strategies such as chemotherapy or radiation. The latter may also be associated with an increased risk of secondary malignancies.[2]
- Generally, it is agreed that small tumors are usually less invasive and that resecting noninvasive small tumors, diagnosed while still asymptomatic, is associated with excellent clinical outcomes with low morbidity and mortality.
- However, when diagnosed at a later stage, the tumor more often affects and invades neighboring structures (fornix, hypothalamus, basal ganglia, and genu of internal capsule) and resection is associated with higher surgical morbidity and mortality.
- Indications of surgery in subependymal giant cell astrocytoma include:[1]
- Acute hydrocephalus
- Worsened seizure burden
- Significant interval growth on serial neuroimaging
