Introduction
Isolated limb infusion (ILI) is an effective, minimally invasive treatment option that delivers high-dose regional chemotherapy to treat metastatic melanoma confined to a limb. In some patients, however, locoregional disease does not respond to the treatment or extensive recurrence occurs so that an amputation may become inevitable. In this study we analyzed indications for and results of amputation in these cases.
Methods
14 patients were identified in whom amputation of the affected limb had to be carried out after failure of ILI.
Results
Following ILI, three patients had a complete response, seven had a partial response, two had stable disease and two patients had progressive disease. The median duration of response after ILI was 7 months (range 2–30). The median interval between ILI and amputation was 10 months. Amputation was performed in six of 20 patients who had been treated with an upper limb ILI, compared to eight amputations that were performed in 215 patients who had been treated with a lower limb ILI (P = .001). The indications for amputation were severe pain due to progression of tumor (n = 3), uncontrollable and troublesome tumor progression (n = 6) and bleeding from ulcerated lesions (n = 5). Five patients developed stump recurrence after amputation; these were treated by excision or radiation. Six of the eight patients who had a lower limb amputation became ambulant with the aid of prosthesis. Median survival after amputation was 13 months: three patients survived more than 5 years.
Conclusions
Amputation following upper extremity ILI is more common compared to lower extremity ILI. Amputation may provide effective long-term palliation in selected patients when there is extensive inoperable progressive or recurrent disease after ILI.
