The round cell form of myxoid liposarcomas also appears to have a relatively poor prognosis: in various retrospective reviews, myxoid liposarcoma was usually found to be low-grade and therefore relatively responsive to chemotherapy whereas high grade (i.e. round cell) myxoid lipsarcoma had higher rates of metastasis, behaved more aggressively, and did not respond well to chemotherapy.
