UNLABELLED: Graves' ophthalmopathy is the most common extrathyroidal manifestation of Graves-Basedow disease. Radiotherapy is effective especially when used in synergy with the administration of glucocorticoids. The aim of our study was to analyze the effectiveness and safety of radiotherapy, using different protocols, to improve ocular symptoms and quality of life.
METHODS: We retrospectively analyzed the clinical data of two-hundred and three patients treated with retrobulbar radiotherapy between January 2002 and June 2023. Ninety-nine patients were treated with a schedule of 10 Gy in 10 fractions and one-hundred and four were treated with 10 Gy in 5 fractions. Radiotherapy (RT) was administrated during the 12 weeks of pulse steroid therapy. Patients were evaluated with a clinical exam, orbital CT, thyroid assessment, and Clinical Activity Score (CAS).
RESULTS: The median follow-up was 28.6 months (range 12-240). Complete response was found in ninety-four pts (46.31%), partial response or stabilization in one hundred pts (49.26%), and progression in nine pts (4.43%). In most subjects, an improvement in visual acuity and a reduction in CAS of at least 2 points and proptosis by more than 3 mm were observed. Three patients needed decompressive surgery after treatment. Only G1 and G2 acute eye disorders and no cases of xerophthalmia or cataract were assessed.
CONCLUSIONS: RT is an effective and well-tolerated treatment in this setting, especially when associated with the administration of glucocorticoids. Although the most used fractionation schedule in the literature is 20 Gy in 10 fractions, in our clinical practice, we have achieved comparable results with 10 Gy in 5 or 10 fractions with a lower incidence of toxicity.
