Long-term results of hyperthermic, isolated limb perfusion for melanoma: a reflection of tumor biology.Sanki A, Kam PC, Thompson JF Sydney Melanoma Unit, Sydney Cancer Centre, Royal Prince Alfred Hospital, Sydney, NSW, Australia. PURPOSE: To review the long-term duration of limb tumor complete remission (CR) and patient survival following therapeutic hyperthermic isolated limb perfusion (ILP) with cytotoxic drugs for melanoma. METHODS: A retrospective case series of 124 ILPs performed in 111 patients. RESULTS: There were 120 assessable ILPs. Patient staging (M.D. Anderson system) was stage II 11.7%, stage IIIA 44.2%, stage IIIAB 33.3%, and stage IV 10.8%. CR was initially attained after 83 ILPs (69.2%) and partial remission (PR) after 19 ILPs (15.8%). Limb CR was maintained in 28 (33.7%) of the 83 cases. Disease recurred in the perfused limb after an initial CR in the remaining 55 cases (median time to recurrence, 11 months); in 19 of these cases, the limb was disease-free at last follow-up after further locoregional treatment. A long-term CR was achieved, with or without further treatment, in 47 (56.6%) of the 83 cases in which an initial CR had occurred (mean follow-up, 97 months; median, 65 months). There was no significant difference in long-term local remission for stage IIIA and IIIAB patients. Five-year survival for those who had a partial or no response to ILP was 7%. Ten-year survival for those who had a long-term CR was 49%. CONCLUSIONS: ILP, with or without further locoregional treatment, achieved long-term control of recurrent and metastatic limb disease in 56.6% of cases in which an initial CR was achieved. A complete response to ILP was a positive prognostic indicator for survival, probably reflecting more favorable tumor biology in this subset of patients.
