[Pathological type of liposarcoma and its effects of clinical treatment]

To study the pathological type of liposarcoma and it effects of clinical treatment, reviewed 21 cases of liposarcoma. Since Oct. 1976 to Dec. 1995, 21 cases of liposarcoma were treated by operation. 15 cases were male and 6 cases female. The onset of the disease occurred between 6-79 years of age with an average of 49.9 years. 13 cases were well-differentiated, 4 Myxoid, 4 cases of andifferentiaed. All cases were followed up with an average of 8.9 years. The 5-, 10-year survival rate was 94%, the 5-, 10-year unrecurernce rate was 72% and 52%. Among the malignant soft tissue tumors liposarcoma, was most common. The survival rate was related to the pathological type, the site and the size. Good clinical results were well-differentiated and myxoid. The poor was retroperitoneal liposarcoma. The smaller the tumor, the better the result. For the treatment, wide margin excision is a good method of choice.
