Second-look surgery for ependymoma: the Italian experience

Object Complete ependymoma resection ensures a better prognosis for children with this tumor, but the complete excision of infratentorial ependymomas involves serious risks. Second-look surgery for tumor remnants may be less harmful and enable complete removal. There is a potential, although still unclear, role for neoadjuvant chemotherapy in preparation for further surgery. Methods Since 1994, the authors have adopted two successive protocols for intracranial ependymoma, both including a phase of adjuvant chemotherapy for children with surgical tumor remnants with a plan for potential second-look surgery before radiotherapy. Results In the first protocol, 9 of 63 children underwent further surgery, and 6 became tumor free with no additional sequelae. Their prognosis for progression-free survival and freedom from local relapse was comparable to that of children who were operated on only once. In the second protocol, efforts were made to achieve complete resection and 29 of 110 patients underwent reoperati...
