Dose Evaluation in Medulloblastoma Cancers

Abstract

Radiotherapy is a common treatment of medulloblastoma carcinoma. Radiotherapy-induced ear injuries remain under-evaluated and under-reported. These reactions may have acute or late character, may affect all structures of the hearing organ, and result sensorineural or mixed hearing loss. Thus, reduction in radiation dose to the auditory structures should be attempted whenever possible. The present study describes the technique used in our clinic for the craniospinal irradiation. The doses to different organs at risk are evaluated and compared to other techniques found in the literature.
