Prognostic value of 18 F-fluorodeoxyglucose positron emission tomography/computed tomography in patients with cutaneous angiosarcoma: A retrospective study of 18 cases.

Cutaneous angiosarcoma (CAS) is a rare soft tissue sarcoma with rapid growth and poor prognosis. We retrospectively analyzed the data of 18 patients with CAS who underwent 18 F-Fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) at the initial visit to the Department of Dermatology, Okayama University Hospital from September 2006 to March 2016. In the univariate survival analysis, patients with high standardized uptake values (SUVmax ) of the primary tumor showed significantly poorer prognosis than those with low SUVmax . Early assessment of prognosis using PET/CT may predict patient survival and is useful in the selection of therapeutic strategies.
