Hierarchical classification of the 99 soft tissue sarcomas using the selected 67 proteins. The dendrogram shows the degree of similarity of protein expression pattern between the tumors. The shorter the branches, the more similar the two joined tumors. Most tumors formed tight clusters corresponding to their histology except leiomyosarcoma and malignant fibrous histiocytoma. RMS = rhabdomyosarcoma; MFH = malignant fibrous histiocytoma; GIST = gastrointestinal stromal tumor; MPNST = malignant peripheral nerve sheath tumor.
