Significant fibrosis after radiation therapy in a patient with Marfan syndrome
Suarez, Eva M.,Knackstedt, Rebecca J.,Jenrette, Joseph M. The Korean Society for Radiation Oncology 2014 Radiation Oncology Journal Vol.32 No.3
Marfan syndrome is one of the collagen vascular diseases that theoretically predisposes patients to excessive radiation-induced fibrosis yet there is minimal published literature regarding this clinical scenario. We present a patient with a history of Marfan syndrome requiring radiation for a diagnosis of a right brachial plexus malignant nerve sheath tumor. It has been suggested that plasma transforming growth factor beta 1 (TGF-${\beta}1$) can be monitored as a predictor of subsequent fibrosis in this population of high risk patients. We therefore monitored the patient's TGF-${\beta}1$ level during and after treatment. Despite maintaining stable levels of plasma TGF-${\beta}1$, our patient still developed extensive fibrosis resulting in impaired range of motion. Our case reports presents a review of the literature of patients with Marfan syndrome requiring radiation therapy and the limitations of serum markers on predicting long-term toxicity.
