The genetic landscape of choroid plexus tumors in children and adults [PDF]

Neuro Oncol, 2020
Background. Choroid plexus tumors (CPTs) are intraventricular brain tumors predominantly arising in children but also affecting adults. In most cases, driver mutations have not been identified, although there are reports of frequent chromosome-wide copy ...

Preoperative Devascularization of Choroid Plexus Tumors: Specific Issues about Anatomy and Embolization Technique [PDF]

Brain Sciences, 2021
(1) Background: Surgical treatment of choroid plexus tumors is challenging, burdened by a notable risk of bleeding. Neoadjuvant chemotherapy and preoperative embolization have been attempted, with encouraging results; however, the consensus on these ...

Methylation profiling of choroid plexus tumors reveals 3 clinically distinct subgroups [PDF]

Neuro Oncol, 2018
BACKGROUND: Choroid plexus tumors are intraventricular neoplasms derived from the choroid plexus epithelium. A better knowledge of molecular factors involved in choroid plexus tumor biology may aid in identifying patients at risk for recurrence. METHODS:
