A modified technique for craniospinal irradiation in children designed to reduce acute and late radiation toxicity

Abstract

Craniospinal irradiation is an important technique for the treatment of a number of paediatric malignancies. The conventional technique uses photons for all fields and does not exploit the benefits of CT and computer planning systems. The present paper describes a modification of the conventional technique in which both photons and electrons are used for the spinal field (mixed-beam technique). Computed tomography images and a planning computer are used for the selection of field junctions, electron beam energy and dosimetry. The intention of the technique is to reduce radiotherapy toxicity. A discussion of the potential benefits is presented.

Static-junction craniospinal irradiation: verification of daily dose and long-term treatment results

“…So far, this is the first study which evaluated CSI treatment planning techniques with regard on the actual everyday treatment delivery implementation, the long-term treatment results and pattern of progression [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. The technique presented in our study is simple and can be easily implemented even in the departments with limited resources.…”

A simple technique for cranio-spinal irradiation in pediatric patients

“…Several methods have been defined to deliver CSI. [1][2][3][4][5][6][7] The implementation of CSI requires at least one junction between the orthogonal cranial and spinal radiation fields. CSI can be performed either in a prone or supine position.…”
