In the present study, we hypothesized that the combination of MIF and SCD1 can serve not only a diagnostic marker for discrimination between MFH and MFS, but also act as a prognostic marker for the overall outcome of STS, since an elevated expression of MIF and SCD1 is observed in various highly malignant tumors [29-32]. Here, MIF is linked to undifferentiated pleomorphic sarcoma.
