Surgical Outcome of Choroid Plexus Tumors in Adults : Experience of 5 Cases

ABSTRACT

A retrospective analysis of five adult patients with choroid plexus tumor(four choroids plexus papillomas, one choroids plexus carcinoma who underwent surgical resection at our institute between February 1991 and October 1995 was performed. The study group included two males and three females with a mean age of 34.0 years(range 21 to 24 years). Two of four choroids plexus papillomas were removed gross totally and one of these was irradiated postoperatively. The remaining two patients with choroids plexus papilloma underwent a subtotal surgical resection and one of them received radiation therapy. During follow-up, the authors could not find any difference in the size of the residual tumor or in the patient's KPS between the irradiated groups. There was also no response to postoperative radiation therapy in a patient with choroids plexus carcinoma who underwent a subtotal resection. The author's clinical experiences suggest that the use of radiation therapy in adult patients with choroids plexus tumor is not effective, and thus gross total resection should be attempted during the primary operation of such tumors.
