Résumé
Objective: To compare IMSRT with IMRT and stereotactic radiotherapy, in terms of target volume coverage and
critical structure sparing, for the treatment of introcular retinoblastoma.
Material and Methods: IMSRT, IMRT, and conventional stereotactic treatment plans were prepared for a test case; 3-yrs old,
recurrent unilateral retinoblastoma. The planning goal was 95% isodose coverage of the PTV with
minimum dose to the optic nerve, bony orbit and lense. Target conformity (total tissue volume receiving
≥ 80%, 50% and 20% dose), optic nerve volume receiving ≥ 50% dose, and the maximum lense dose
were evaluated.
Results: The central nervous system volume and bony orbit volume encompassed by the 20% and 50% isodoses
respectively, was significantly less for IMRST and stereotactic radiotherapy than for IMRT. Doses to the
lense and lacrimal gland were reduced with IMSRT, but optic nerve sparing was not improved.
Conclusion: Stereotactic treatment is the best method for linac-based treatment of intraocular retinoblastoma.
Compared with conventional stereotactic treatment, IMSRT slightly improves the sparing of organs at
risk.
