Paraganglioma is rare cancer and most of what is known about how to treat it comes from case reports and small case series. The optimal systemic treatment for advanced disease is undefined, due in part to lack of effective agents. There are several reports of tens of patients suggesting that Sutent is an active agent for this condition. A 2017 report and literature review (Canu et al) says: ” Sunitinib seems able to slow the disease progression in some patients with malignant PHEO/PGL and therefore may represent a therapeutic option, although randomized controlled studies are needed to assess its efficacy definitively in the treatment of these aggressive tumors.”.
