We examined the treatments and prognosis in 28 cases of malignant soft tissue tumors in patients 65 years aged or older from 1977 to 1995. The mean age was 73 years. Histologic diagnoses were as follows, malignant fibrous histiocytoma (MFH) in 18 cases, liposarcoma in four cases, synovial sarcoma in three cases, malignant schwannoma in two cases and leiomyosarcoma in one case. Twenty six of 28 cases were treated surgically, and the others were treated conservatively. The over all fiveyear survival rate was 53%. In regard to MFH, the cases of upper extremity tumor seemed to have a better prognosis than those of the lower extremity and trunk.
