Abstract
In a series of 241 soft tissue tumors at our clinic, 228 benign and 13 malignant tumors were found.
The benign tumors were classified into 118 ganglia, 12 lipomatoses, 9 angiomatoses, 8 fibromatoses, 2 pigmented villonodural synovitis and one myositis ossificans generalisata. 163 of the tumors were in females but they were encountered at any age.
The malignant tumors were composed of 6 fibrosarcomata, 2 synovial sarcomata, 2 sarcomata of undetermined histogenesis, one hemangiosarcoma, one rhabdomyosarcoma and one liposarcoma.
They occurred in patients from sixteen to seventy-two years of age. The sex incidence was about equal. Reccurrence in six patients with a recurrence rate of 46 per cent was observed and the average time for development of recurrence was ca. one year. Four patients with the tumors, three of whom were administered by intraarterial infusion, have survived. Metastatic rate was 68 per cent and the average time for occurrence of the metastasis after the operation was ca. one year. The five-year cumulative survival rate was 34.8 per cent.
