Long-term results of a double perfusion schedule using high dose hyperthermia and melphalan sequentially in extensive...

The aim of this study was to assess the results of an isolated limb perfusion (ILP) schedule with high dose hyperthermia (42-43 degrees C) and melphalan, applied sequentially in patients with advanced melanoma of the limbs. Seventeen patients with extensive recurrent or bulky melanoma of a limb were treated with hyperthermic femoral ILP (42-43 degrees C) without drugs followed by normothermic (37-38 degrees C) ILP with melphalan. Eleven patients (65%) had a complete response. Three patients (27%) had limb recurrences after 5, 6 and 18 months, respectively. The 5 year limb recurrence-free interval for patients with a complete response was 63%. Limb toxicity was mild; pressure-related blistering and transient sensory disturbances occurred after the hyperthermic ILP, and 88% of the patients had a grade II reaction (mild erythema and oedema) after the second ILP. This sequential ILP schedule resulted in a high complete response rate and a low limb-recurrence rate in patients with extensive, recurrent melanoma of the limbs at the cost of only mild toxicity. This regimen could be an alternative to ILP with tumour necrosis factor-alpha and melphalan.
