The immunohistochemistry staining of the tumor specimens showed pan-cytokeratin (pan-CK) (+), Ki67 (+), Heppar-1 (−), CAM5.2 (+), Vimetin (+), CK19 (−), and SMA (+) (Supplementary Figure S2), which are associated with the clinical characteristics of sarcoma patients [35–38]. This evidence concerns the gene MKI67 and neoplasm.
