[Combined therapy of intracranial germ cell tumors in children]

A retrospective analysis of treatment of 8 children aged 5 to 13 years with intracranial germ cell tumors (3 germinomas, 5 nongerminomatous cell tumors) is reported. All patients were initially operated. Five of them underwent total or incomplete removal of the tumor. After surgery 2 children received radiotherapy alone (1 germinome, 1 nongerminomatous germ cell tumors) and 5 (2 germinomas, 3 nongerminomatous germ cell tumors) combined radio- and chemotherapy. One patient (choriocarcinoma) didn't receive any adjuvant treatment after total tumor removal. All 3 children with germinomas show complete remission for 29, 40 and 93 months. Of 5 patients with nongerminomatous germ cell tumors in 2 the duration of remission was 22 and 53 months and 3 relapsed 4, 12 and 24 months after treatment. The data presented demonstrate that the treatment results of intracranial germ cell tumors in children depend on histologic type of the tumor. Thus, precise tumor type determination is most important for choosing optimally adequate treatment approach.
