Abstract
Seventy patients with invasive malignant melanoma confined to one limb were treated by isolated perfusion with 1-phenylalanine-dihydrochloride (melphalan) and regional lymphadenectomy between 1959 and 1979. Five patients were perfused twice. This treatment did not modify the results of appropriate local excision in early melanoma. Twenty-one patients with stage I disease have had 76 per cent 5-year survival. Forty-eight per cent of 29 patients with extensive local recurrent tumour showed marked tumour regression. Nine of these had subsequent local recurrence with a mean remission of 7 months. Survival in those who responded was 2 years longer than in those who did not. In 6 patients with slight local recurrence, and 19 patients with regional node metastases, response could not be assessed directly. Their 5-year survival was 52 per cent. There have been no deaths as a result of the procedure and no amputations. Mean postoperative hospital stay was 25 days. We conclude that this technique has a useful place in the palliation of extensive local recurrent melanoma.
