title: Stereotactic radiotherapy as an alternative to plaque brachytherapy in retinoblastoma.
abstract: Radioactive plaque brachytherapy has an established role for selected patients with retinoblastoma. Newer non-invasive radiotherapy techniques such as stereotactic conformal radiotherapy (SCR) that uses highly accurate positioning to deliver treatment with small beams may be an interesting alternative to brachytherapy. We report a case treated with SCR and compare the dosimetry with that achievable with brachytherapy. With advantages and disadvantages to both, SCR should more often be considered in the management of RB because of the more homogeneous dose within the target volume and similar or lower doses to surrounding normal tissues.
