    Abstract:
    OBJECTIVE: To analyse a personal series of cases of malignant melanoma of a limb with regional metastasis treated by isolated cytostatic perfusion of both recombinant human tumour necrosis factor (rhTNF-alpha) and melphalan, reported to produce a response rate of up to 100%. PATIENTS AND METHODS: 23 isolated hyperthermic regional perfusions were performed between 1993 and 1995 in 21 patients (17 women, four men) with proven regionally metastatic malignant melanoma of the limb, using rhTNF-alpha and melphalan in combination. Perfusion time was 90 min, at a tissue temperature of 38 degrees to 40 degrees C and a perfusion pressure 10-15 mm Hg below mean arterial. RESULTS: All systemic effects of the limb perfusions were easily manageable under intensive care monitoring. There were no severe disturbances (WHO grade 3/4) of cardiovascular or pulmonary functions. One patient, who had sustained a marked leak during the perfusion, died two days after the perfusion of severe pneumonia and pulmonary emboli from a femoral vein thrombosis. Two further perfusions were terminated because of a leakage rate of more than 10%. A rise in bilirubin and the transaminases occurred in 11 of the 23 perfusions up to WHO grade 2 (n = 9) and 3 (n = 2). Renal functions were temporarily impaired in three of the 21 patients (WHO grade 1). Complete tumour regression was obtained in 13 patients, a partial one in three (response rate 80%). After a median follow-up period of 15 months five of the 13 patients developed a regional recurrence. CONCLUSION: The observed response rate is higher than that with melphalan alone as reported in the literature. To clarify this difference a randomized phase III study comparing the two methods has been initiated.
