Global protein-expression profiling for reclassification of malignant fibrous histiocytoma

Abstract

According to the newest World Health Organization (WHO) classification for soft tissue tumors in 2013, malignant fibrous histiocytoma (MFH) has been gone. Most sarcomas called MFH were reclassified to be high-grade pleomorphic forms of leiomyosarcoma, liposarcoma, rhabdomyosarcoma, and other sarcomas by recent molecular technologies. However, about 10% to 15% of sarcomas called MFH before, still cannot be given a precise classification, and these are now called undifferentiated pleomorphic sarcoma or are still called MFH. Further molecular approaches including proteomic approaches are imperative to classify these unclassified sarcomas for improving clinical outcomes of the patients with soft tissue sarcomas. This article is part of a Special Issue entitled: Medical Proteomics.
