Different conceptions exist regarding the epidemiology and prognosis of liposarcoma, and several classification systems are in use.
We analyzed a population-based, 25-year series of 43 patients with liposarcoma of the extremity or trunk wall.
Follow-up was complete.
The annual incidence was 0.12/105.
The thigh was the most common location.
One of 6 tumors was subcutaneous.
Deep-seated tumors were larger than s.c. tumors.
Among the 42 surgically treated patients, grade II (4-grade scale) was the most common malignancy grade.
Four tumours were well-differentiated, 24 were predominantly myxoid, 4 predominantly round-cell, and 10 were predominantly of pleomorphic type.
The 5-year metastasis-free survival rate was 69%.
