Overview
Natural History
- The natural history of liposarcoma would depend on the histopathological subtype and location.
- Liposarcomas may remain asymptomatic for a long time, specially if they are located in the retroperitoneum.
- The common presentation for a liposarcoma located in the soft tissue of the skin is a painless growing mass without other symptoms.
- The lower extremities are the most common location of liposarcomas. [1]
- Between 10 and 15% of patients may present with pain in the affected region. [1]
- Retroperitoneal liposarcomas may present as a dull abdominal pain, weight loss and increase abdominal girth.
Complications
- Liposarcoma may cause metastasis to other organs and the lung is the most common location for metastatic disease.
Prognosis
- The prognosis of liposarcoma will depend on the histopathological subtype.
- Atypical lipomatous neoplasm/well-differentiated liposarcoma has a low metastasis risk, but may recur locally. The prognosis for this subtype is better than for other subtypes of liposarcoma.[1]
- The pleomorphic liposarcoma has a high metastasis potential and a high recurrence.
- The 5-year disease free survival rate for liposarcoma located in the extremities is 74%.[2]
