Objective: Solitary fibrous tumor is a rare tumor occurring in almost every anatomic location of human body; however, reports of malignant solitary fibrous tumor in the nasal and paranasal area are especially rare. In this report, we describe a case of non-recurrent malignant solitary fibrous tumor of the nasal and paranasal area.
Methods: The patient was initially treated with nasal and paranasal tumor cytoreductive surgery, followed by post-operative three-dimensional conformal intensity modulated radiation therapy (dynamic MLC Varian 600CD Linac, inversely optimized by the Eclipse system) and stereotactic body radiation therapy to provide a radical cure for residual tumor.
Results: The tumor of the nasal and paranasal area was effectively treated and the integrity of the right eye kept. There were no signs of recurrence after four and a half years of further follow-up.
Conclusions: This is the first attempt to successfully combine cytoreductive surgery with intensity modulated radiation therapy and stereotactic body radiation therapy together to treat solitary fibrous tumor of the nasal and paranasal area, which may provide a potential strategy for the treatment of similar cases.
