Radiation therapy for Graves' ophthalmopathy: a retrospective analysis

Area of Science:

• Ophthalmology
• Endocrinology
• Radiation Oncology

Background:

• Graves' ophthalmopathy is an autoimmune condition affecting the eyes.
• Many patients present with advanced disease, often requiring prior treatments like steroids or surgery.
• Evaluating the efficacy of radiation therapy (RT) in managing complex cases is crucial.

Purpose of the Study:

• To assess the effectiveness of radiation therapy (RT) in treating patients with Graves' ophthalmopathy.
• To determine the impact of RT on various clinical signs and symptoms of the condition.
• To evaluate the reduction in steroid dependency post-RT.

Main Methods:

• Retrospective analysis of 29 patients with Graves' ophthalmopathy treated between 1973 and 1986.
• Patients received radiation therapy (RT) for advanced disease, with many having prior treatments.
• Outcomes were evaluated by a multidisciplinary team (Radiation Oncologist, Ophthalmologist, Endocrinologist) with a median follow-up of 45 months.

Main Results:

• Overall improvement in signs and symptoms was observed in 48% of patients.
• Significant relief was noted for soft tissue changes (78%) and proptosis (52%).
• Ophthalmoplegia showed limited response (24% improvement), and 90% of patients discontinued steroid use post-RT.

Conclusions:

• Radiation therapy (RT) can be effective in managing Graves' ophthalmopathy, particularly for soft tissue changes and proptosis.
• RT significantly reduces the need for steroid treatment in most patients.
• Combined modality treatment, including surgery, may be necessary for advanced or refractory cases following RT.
