Malignant fibrous histiocytoma of soft tissue. An analysis of 78 cases located and deeply seated in the extremities.
Seventy-eight cases of malignant fibrous histiocytoma (MFH) of soft tissues are reported. All tumors were deeply located in the extremities. An analysis is presented with regard to sex, age, site, macro- and microscopic features. The staging was assessed according to Enneking's classification (IB, one case; IIA, 25 cases; IIB, 42 cases; III, 10 cases). The recurrence rate after surgical treatment was high (37.5%) with significant differences after inadequate surgery (70%), wide excision (38%), or amputation (0%). Adjunctive radiotherapy rarely was effective in preventing local recurrence. The overall 5-year survival rate was 36%. The prognosis was worse in (1) tumors larger than 5 cm in diameter, (2) tumors that recurred early (less than 1 year) after surgery, and (3) tumors that had inadequate surgical treatment (intralesional or marginal excision).
