Figure 1.

Hierarchical cluster analysis of 51 soft tissue sarcoma specimens using global gene expression profiles revealed distinct clusters for GIST, synovial sarcoma, clear cell sarcoma and round cell liposarcoma. Several conventional fibrosarcoma were observed in close proximity to synovial sarcoma, albeit with weaker correlation. Pleomorphic specimens exhibited weak overall correlation and consistency by bootstrap analysis. Predominant clusters were similarly observed for MFH and leiomyosarcoma. Numbers represent consistency obtained in 100 bootstrap iterations. Cases are shown on the x axis.
