Background: Melphalan (L-PAM) hyperthermic isolated limb perfusion (HILP) is currently considered the standard treatment for patients with in-transit metastases from cutaneous melanoma. We here report on the results of L-PAM and low-dose tumor necrosis factor (TNF)alpha HILP in patients with bulky disease. Methods: Twenty patients underwent TNFalpha (1 mg) and L-PAM (10 mg/L) HILP. Perfusion was performed for 90 minutes, and systemic leakage was strictly monitored. Locoregional toxicity was evaluated according to Wieberdink's criteria, whereas tumor response was evaluated with physical examination and ultrasound scan with or without fine-needle aspiration of any suspected recurrence. Results: In all cases, systemic leakage was <5%. No postoperative deaths occurred, and locoregional toxicity was mild (grade 1 or 2) in 95% of patients. A complete tumor response was obtained in 14 patients (70%), and partial responses were obtained in 5 patients (25%). After a median follow-up of 18 months, six patients are alive and disease free, seven are alive with local or distant recurrence or both, and seven have died of disease. Conclusions: Low-dose TNFalpha HILP can achieve tumor responses comparable with those reported with higher doses of cytokine. Moreover, this drug regimen is associated with acceptable local toxicity, carries a smaller risk of systemic toxicity, and incurs lower costs

Abstract

Background: Melphalan (L-PAM) hyperthermic isolated limb perfusion (HILP) is currently considered the standard treatment for patients with in-transit metastases from cutaneous melanoma. We here report on the results of L-PAM and low-dose tumor necrosis factor (TNF)alpha HILP in patients with bulky disease. Methods: Twenty patients underwent TNFalpha (1 mg) and L-PAM (10 mg/L) HILP. Perfusion was performed for 90 minutes, and systemic leakage was strictly monitored. Locoregional toxicity was evaluated according to Wieberdink's criteria, whereas tumor response was evaluated with physical examination and ultrasound scan with or without fine-needle aspiration of any suspected recurrence. Results: In all cases, systemic leakage was <5%. No postoperative deaths occurred, and locoregional toxicity was mild (grade 1 or 2) in 95% of patients. A complete tumor response was obtained in 14 patients (70%), and partial responses were obtained in 5 patients (25%). After a median follow-up of 18 months, six patients are alive and disease free, seven are alive with local or distant recurrence or both, and seven have died of disease. Conclusions: Low-dose TNFalpha HILP can achieve tumor responses comparable with those reported with higher doses of cytokine. Moreover, this drug regimen is associated with acceptable local toxicity, carries a smaller risk of systemic toxicity, and incurs lower costs
