The prognosis of paratesticular liposarcomas depends on the histological cell type, among well-differentiated, dedifferentiated, pleomorphic and myxoid/round cell types.
The median survival times observed for well differentiated, dedifferentiated, myxoid, and pleomorphic tumors were 104 (71.43, 136.57), 18 (0.52, 35.48), 65 (4.51, 125.50), and 29 (0.00, 74.09) months, respectively.

It has been shown that progenitor or stem cells which are enriched with [CD133.sup.+] and OCT-4 have higher colony-forming capacity [5], in addition, the expression of OCT-4 in dedifferentiated cells leads to cancer stem-like cell features with the acquired ability to form tumor spheroids, increased resistance to chemotherapeutic agents, and increased tumorigenic capacity [28].
