Results of hyperthermic perfusion for melanoma of the extremities.

Abstract

Our studies show that the malignant melanoma cell in human beings is more sensitive to the lethal effect of heat than its normal counterpart, the melanocyte. Malignant melanoma of the extremities presents unique problems; at times, local control can be extremely difficult. The addition of heat to regional perfusion with melphalan has dramatically improved the objective response of melanoma. Complications rise as the tempreature and duration of perfusion increase. These risks must be weighed carefully against the volume and extent of tumor. One hundred and eighty-five hyperthermic perfusions have been perfomed on 165 patients. When done with meticulous attention to details, this procedure is accompanied by minimal morbidity and mortality. Hyperthermic perfusion is currently the best treatment for recurrent melanoma of the extremities and has almost eliminated the necessity for amputation. Perfusion is recommended as a prophylactic measure for the more deeply invasive primary lesions. It reduces the incidence of regional recurrence. A retrospective statistical analysis of survival rates of patients treated with nonheated and heated perfusion for recurrent melanoma, State IIIA, was conducted. If the experience of the heated group continues, which from a clinical standpoint appears likely, then a striking advantage of heated perfusion over nonheated perfusion will be demonstrated. This superiority in survival rates for the heated group is now three to one or 300 per cent. The most reasonable explanation for the improvement in survival time of patients in State IIIA is stimulation of the immune response. As a result of our experience with heated perfusion of limbs, we are investigating the possibility that systemic hyperthermia may enhance the antitumor effects of various chemotherapeutic agents on melanoma.
