Abstract

Choroid plexus tumors (CPTs) are rare neoplasms of the central nervous system whose optimal management is not well defined. The Surveillance Epidemiology and End Results (SEER) Database from 1978 to 2009 was queried to define population-based outcomes for all patients with CPTs. Patient demographic data, histological classification (choroid plexus papilloma [CPP], atypical CPP [aCPP], and choroid plexus carcinoma [CPC]), extent of surgery, and use of radiation therapy (RT) as part of an initial course of therapy were analyzed for impact on overall survival (OS) and cause-specific survival (CSS). Chemotherapy data were not available within the SEER database. A total of 349 patients with CPTs were identified (120 CPCs, 26 aCPPs, and 203 CPPs). Patients with CPC presented at a younger age (median 3, mean 14.8 years) relative to CPP (median 25, mean 28.4 years; p < 0.0001). Histology was a significant predictor of OS, with 5-year OS rates of 90, 77, and 58 % for CPP, aCPP, and CPC, respectively. Older age and male sex were prognostic for worse OS and CSS for CPP. Only extent of surgery had a significant impact on survival for CPC. The use of adjuvant RT in patients with CPC undergoing surgery was not associated with a significantly improved OS (p = 0.17). For patients undergoing GTR without RT as part of an initial course of therapy, estimated 5- and 10-year OS were 70 % (±7 %) and 67 % (±8 %), respectively. Prospective data are required to define the optimal combination of surgery with adjuvant therapies, including chemotherapy.
