[Radiotherapy of inoperable brain tumors in childhood].

Study Objective: Description and evaluation of radiotherapy of inoperable tumours of central nervous system. New possibilities in radiotherapy planning.

Materials And Methods: Between 1987 and 2004, 58 patients (30 boys and 28 girls, mean age 8.

Effects of radiation treatment planning and patient fixation on the results of postoperative radiotherapy of childhood medulloblastoma.

Purpose: To assess the prognostic factors and the benefit of introducing head fixation and CT-assisted radiation treatment planning following postoperative radiotherapy in 83 children with medulloblastoma.

Patients And Methods: In 24 children treated between 1986 and 1994, no head fixation was applied and boost irradiation was not based on individual radiation treatment planning. Since 1995, boost irradiation has been assisted by CT-based individual radiation treatment planning and ORFIT head fixation in 59 patients.
