Comparison of published risk models for prediction of outcome in patients with extrameningeal solitary fibrous tumour

Solitary fibrous tumours (SFTs) are fibroblastic mesenchymal tumours with a 10–30% metastatic rate. Several risk models have been proposed for extrameningeal SFT, but they have not been evaluated in direct comparison with each other. The aim of this study is to compare the utility of published risk models in a multi‐institutional SFT cohort.
