    Abstract:
    INTRODUCTION: In the treatment of patients with advanced limb melanoma a major treatment dilemma can arise when distant metastases are present also. Isolated limb infusion (ILI) has proved to be a useful limb-saving treatment and could potentially be of palliative value in patients with American Joint Committee on Cancer (AJCC) stage IV melanoma. METHODS: We identified 37 patients with advanced symptomatic limb disease as well as documented distant metastases at the time of their ILI. In all patients a drug combination of melphalan and actinomycin D was used. RESULTS: Fifty one percent had visceral distant metastases and 49% had cutaneous distant metastases only. The overall response rate in the treated limb was 76% [complete response (CR) rate 22%, partial response (PR) rate 54%]. Median response duration was 11 months (28 months for patients with CR; p = 0.08). Median survival after CR was 22 months, 17 months after PR, and only 4 months for those with stable or progressive disease (p = 0.002). Patients with visceral distant metastases had a significantly decreased survival compared with those with cutaneous distant metastases only (8 and 21 months, respectively; p = 0.03). Limb salvage was achieved in 86% of the patients. The procedure was well tolerated, with only one patient developing Wieberdink grade IV toxicity (threatened/actual compartment syndrome) and none requiring amputation as a result of the procedure (grade V toxicity). CONCLUSIONS: Minimally invasive ILI can effectively be used as palliative treatment to provide local tumor control and limb salvage in stage IV melanoma patients with advanced, symptomatic limb disease.
