Hyperthermic limb perfusion for malignant melanoma and soft tissue sarcoma.

From 1982-1989, 113 hyperthermic limb perfusions were carried out in 102 patients. Ninety-three patients were treated for malignant melanoma and nine for soft tissue sarcoma. 47/93 patients had high-risk stage I melanoma with a 5-year survival rate of 89%. For the 46 patients treated for recurrent and metastatic melanoma the projected 5-year survival rate was 40%. The nine patients with soft tissue sarcoma were perfused for local recurrences or because of anatomically difficult tumor locations. 3/9 patients subsequently developed recurrent disease of the extremity; two of these patients had to be treated by amputation. The rate of major complications was low: no patient died in the postoperative course, an amputation due to toxic reaction was never required. Erythema and oedema (57%), severe skin reaction (6%) and transient nerve palsy (15%) were common side effects of therapy. Only two cases of leucopenia were observed (2%). The favourable results after hyperthermic limb perfusion show the efficacy of this method in the treatment of malignant melanoma and selected cases of soft tissue sarcoma.
