(106)Ruthenium brachytherapy for ciliary recurrence with supraciliary effusion in retinoblastoma

Abstract

Purpose: A 2-year-old boy with syndromic bilateral retinoblastoma resulting from a (del(13)(q12.3q14.3)) developed a recurrent tumor measuring 2.3 X 2.3 mm at the ora serrata 15 months following last treatment.

Methods: Ultrasound biomicroscopy (UBM) revealed a mass invading the ciliary body 6.6 mm in diameter associated with a localized supraciliary effusion.

Results: Complete tumor regression was achieved 1 month after brachytherapy with a (106)Ruthenium plaque. There was no recurrence at 16 months.

Conclusion: This is the first clinical demonstration of supraciliary effusion in recurrent retinoblastoma. Brachytherapy appears to be effective in the treatment of this type of recurrence.
