Prognosis of solitary fibrous tumors: a multicenter study.

Background: Solitary fibrous tumors (SFTs) are rare mesenchymal tumors, and data regarding outcome and prognostic factors are scarce. We report the outcome and analysis of prognostic factors of a retrospective multicenter cohort study for patients treated for SFTs.

Methods: Retrospective analysis was performed of patients treated for SFTs between 1995 and 2012.
