The intent of this study is to determine if intra-arterial chemotherapy is a safe and effective option for subjects with atypical choroid plexus papilloma and choroid plexus carcinoma prior to receiving second-look surgery. Angiography occurs when a catheter is inserted through the subjects vasculature to the major vessels that supply cerebral circulation. Subjects on this trial will undergo a a cerebral angiogram to determine the ideal arteries to use for drug infusion. Once identified, chemotherapy will be delivered through the catheter directly to the site of tumor.
This study will test the safety and efficacy of intra-arterial chemotherapy in subjects with newly diagnosed, residual, or recurrent atypical choroid plexus papilloma and choroid plexus carcinoma prior to a second surgery.~It is believed that intra-arterial chemotherapy will be safe and feasible for this population and will result in decreased tumor size, which may further improve the goals of a second-look surgery.
