The usual postsurgical treatment for patients with pineoblastoma begins with radiation therapy, although some trials have used preradiation chemotherapy. The total dose of radiation therapy to the tumor site is 54 Gy to 55.8 Gy using conventional fractionation.[13,14]

Craniospinal irradiation with doses of 23.4 Gy to 36 Gy are also recommended because of the propensity of this tumor to disseminate throughout the subarachnoid space.[13,14,17]
