Abstract
Objective: To report the first stereotactic treatment of retinoblastoma using a micro-multileaf (mMLC) collimator.
Material and Methods: A standard mask used for fractionated stereotactic treatment was modified for the treatment of bilateral
retinoblastoma by adding an eye immobilisation device to the mask support. Stereotactic mMLC and
conventional (opposed lateral beams) treatment plans were compared using treatment planning based
dose volume histograms. The first patient was treated in November 2004.
Results: Stereotactic treatment using noncoplanar, mMLC shaped beams reduces dose to the ipsilateral organs at
risk and spares the contralateral organs at risk. The immobilisation device developed for the eye provides
precise positioning and was well tolerated by the patient.
Conclusion: Lateral irradiation techniques for bilateral retinoblastoma are frequently followed by complications.
Stereotactic irradiation using a mMLC is a feasible and promising alternative to conventional treatment
that does not require the fabrication of special collimators.
