A management strategy for intraventricular subependymal giant cell astrocytomas in tuberous sclerosis complex

Abstract: Object Subependymal giant cell astrocytomas (SEGAs) are benign tumors, most commonly associated with tuberous sclerosis complex (TSC). The vast majority of these tumors arise from the lateral ependymal surface adjacent to the foramen of Monro, therefore potentially encroaching on one or both foramina, and resulting in obstructive hydrocephalus that necessitates surgical decompression. The indications for surgery, intraoperative considerations, and evolution of the au… Show more

“…Strong expression of these miRNAs was also detected in SEGAs, which are low-grade, slow-growing glial tumors that usually develop in children and adolescents with TSC and represent a major cause of morbidity and mortality (Harter et al, 2014;Ouyang et al, 2014). miR21 recently emerged as one of the important dysregulated miRNAs in gliomas, possibly involved in the regulation of migration and survival of glioma cells (Krichevsky and Gabriely, 2009;Kumarswamy et al, 2011;Moore and Zhang, 2010;Natsume et al, 2011).…”

“…Among those, only 22 shunt insertions were reported (26%). [ 16 ] Moreover, 86% of these shunts (19/22) were inserted after the tumor was resected. [ 13 ] This may reflect the current trend, favoring initial surgical resection over shunt placement.…”

“…Subependymální obrovskobuněčný astrocytom (subependymal giant cell astrocytoma -SEGA) je nádor mozku nízkého stupně malignity (stupeň 1) spjatý s TSC. Jde o benigní nádor, přestože v mikroskopickém obraze mohou být u ně kte rých případů přítomny vaskulární proliferace, nekrózy a mitotické figury [2,19,20] [21][22][23]. Případy symptomatického SEGA jsou však popsány i u dětí mladších tří let [9].…”

“…I přes rozvoj neurochirurgických technik (transkalózní přístup, neuroendoskopické techniky aj.) není ve všech případech radikální chirurgická resekce SEGA možná, a to především u rozsáhlých, bilaterálních či vícečetných lézí, u nichž existuje významné riziko pooperačního neurologického defi citu [22,23,25]. Z chirurgického řešení SEGA profi tují pacienti, u nichž je dosaženo primárního cíle bezpečné radikální resekce, což jsou pacienti s jednoznačně rostoucí unilaterální lézí při foramen Monroi [23,25].…”
