Hyperthermic Isolation-perfusion with Melphalan. A Preliminary Appraisal of Local and General Effects in Malignant Melanoma

Ten hyperthermic isolation-perfusions with melphalan were performed for invasive malignant melanoma of the limbs. Four cases at stage II and with in transit metastases (up to 15 cm in diameter) had a complete regression. However, no improvement of survival was noticed: 4 out of 5 stage II patients who died, within 1 year after perfusion, developed a generalized disease. Systemic chemotherapy was administered in 3 patients after perfusion, but they died from distant metastases. The need for an adequate adjuvant treatment added to isolation perfusion is discussed.
