title: Prophylactic hyperthermic limb perfusion in stage I melanoma.
abstract: Ninety-three patients with stage I primary cutaneous malignant melanoma of the lower limb were treated by wide local excision and hyperthermic isolated regional perfusion with melphalan (L-phenylalanine dihydrochloride) in a prospective non-randomized study between 1976 and 1982. Eighteen patients (19.4%) developed recurrent melanoma. Nine had recurrent regional disease, one with in transit metastases and eight with positive regional nodes. Nine patients developed distant metastases. No patient had locally recurrent disease. This series confirmed the close correlation between tumour microstaging, melanoma recurrence and survival. Seventy-nine per cent of patients were disease-free at 5 years. Males had deeper lesions (mean 4.56 mm) and increased recurrence (33%) than females (mean 3.36 mm and 13%). Superficial spreading melanoma had the most favourable prognosis of the three histological types. Overall survival was 83% (female 86%; males 64%) at 5 years. Significant morbidity occurred in two patients with deep vein thrombosis. Adjuvant therapy using hyperthermic regional perfusion provides improved local and intransit control of limb melanoma.
