Context: Treatment of Fibroblastic and Myofibroblastic Tumors
Low-grade fibromyxoid sarcoma is a histologically deceptive soft tissue neoplasm that most commonly affects young and middle-aged adults. It is commonly located deep within the extremities.[103-105]
A Children's Oncology Group (COG) trial (ARST0332 [NCT00346164]) enrolled 11 patients with this tumor type. The median age at diagnosis was 13 years, and males were more commonly affected. The most common tumor sites were the lower and upper extremities (n = 9). None of the patients developed local or distant disease recurrence at a median follow up of 2.7 years.[106]
