"Most undifferentiated pleomorphic sarcomas are high grade (3 and 4) and are aggressive in their biological behaviour. They frequently metastasise (30-50% at diagnosis 2) and locally recur despite aggressive treatment. The overall 5-year survival is between 25-70% 1,4."

"Examples"
"Typically, undifferentiated pleomorphic sarcomas occur in adults (range 32-80; mean 59 years) with a slight male predilection (M:F 1.2:1) 3."
"Plain radiographs will demonstrate a soft tissue mass and if arising from bone, then appear as an aggressive destructive bony lesion. In some cases, curvilinear or punctate regions of calcification may be demonstrated."
