Distance evaluation of spindle cell and pleomorphic sarcoma samples from five sarcoma types. (a) Scheme of distance calculation. Each dot represents a sample colored according to its histology. Each × -mark represents the centroid of each histological type of sarcoma. Each arrow indicates the distance from a sample to a centroid colored by the histology. (b) Distances of 40 control samples from the five centroids. Note that the closest centroids matched their histology. (c) Distances of 21 MFH samples from the five centroids. DDLS, dedifferentiated liposarcoma; MFS, myxofibrosarcoma; LMS, leiomyosarcoma and FS, fibrosarcoma.
