Radiation Therapy Techniques For Pediatric Cancers
A wide variety of radiotherapy techniques are currently used in childhood cancers. The most common is 3D conformal radiotherapy (3DCRT) which uses multiple beams to focus treatment on the target while shielding as much as possible the surrounding normal tissues.

In some childhood tumors, it is important to deliver treatment to larger volumes. An important example is childhood medulloblastoma. In these children, radiotherapy fields include the brain and the entire spine in order to irradiate the entire cranio-spinal axis. Such an approach is referred to as “craniospinal” irradiation.

Select childhood tumors may be treated with a novel form of radiotherapy treatment planning and delivery, known as intensity modulated radiotherapy (IMRT).
Unlike conventional approaches, IMRT using highly modulated beams designed using sophisticated computerized optimization planning. When cast into the patient, these modulated beams better conform the radiation dose to the shape of the tumor in 3-dimensions, further reducing the volume of normal surrounding tissues receiving high doses.
