Davis et al investigated 30 cases of liposarcomas in the head and neck region and reported crude disease-specific survival was 100% for ALT/WDL and myxoid liposarcoma, but 60% for round cell and 45% for pleomorphic liposarcoma.[79] This finding suggests that discrimination of the histological subtype of liposarcoma is pivotally important in predicting the prognosis.[66]. The gene discussed is GPT; the disease is myxoid liposarcoma.
