Current management of choroid plexus carcinoma in children.
Eleven children with choroid plexus carcinoma are reviewed with respect to presentation, radiographic diagnosis, treatment and pathologic histology. These cases accumulated over a 33-year period and represent 39% of all of our choroid plexus tumors (n = 28). Characteristically, choroid plexus carcinomas are associated with a poor prognosis for long-term survival. Unfortunately, efforts at total resection are hindered in part by the extreme vascularity of the tumor which itself may be of considerable volume. We have recently treated four children who had biopsy or minimal resection of their tumor after which adjuvant chemotherapy was given. Chemotherapy is not curative but it does cause a reduction in tumor volume and, more importantly, has tended to reduce the tumor vascularity. This allows for a second stage operation which is more safely performed and typically allows for more complete tumor removal. At this point, our length of follow-up is insufficient to conclude if total removal in this manner significantly increases survival but it would seem that consistent gross total removal may be an initial step toward better overall management and prognosis in this tumor type.
