Craniospinal irradiation for trilateral retinoblastoma following ocular irradiation.
A case study is presented. Craniospinal radiotherapy and a three-fold pineal boost for trilateral retinoblastoma were delivered to a patient previously irradiated for ocular retinoblastoma. The availability of CT-based three-dimensional treatment planning provided the capability of identifying the previously irradiated volume as a three-dimensional anatomic structure and of designing a highly customized set of treatment beams that minimized reirradiation of that volume.
