| Immunotherapy is associated with durable clinical benefit in patients with melanoma. The goal of this article is to provide evidence-based consensus recommendations for the use of immunotherapy in the clinical management of patients with high-risk and advanced-stage melanoma in the USA. To achieve this goal, the Society for Immunotherapy of Cancer sponsored a panel of melanoma experts-including physicians, nurses, and patient advocates-to develop a consensus for the clinical application of tumour immunotherapy for patients with melanoma. The Institute of Medicine clinical practice guidelines were used as a basis for this consensus development. A systematic literature search was performed for high-impact studies in English between 1992 and 2012 and was supplemented as appropriate by the panel. This consensus report focuses on issues related to patient selection, toxicity management, clinical end points and sequencing or combination of therapy. The literature review and consensus panel voting and discussion were used to generate recommendations for the use of immunotherapy in patients with melanoma, and to assess and rate the strength of the supporting evidence. From the peer-reviewed literature the consensus panel identified a role for interferon-α2b, pegylated-interferon-α2b, interleukin-2 (IL-2) and ipilimumab in the clinical management of melanoma. Expert recommendations for how to incorporate these agents into the therapeutic approach to melanoma are provided in this consensus statement. Tumour immunotherapy is a useful therapeutic strategy in the management of patients with melanoma and evidence-based consensus recommendations for clinical integration are provided and will be updated as warranted.

Objective: High-dose interleukin-2 (IL-2) is effective immunotherapy for the treatment of metastatic melanoma and renal cell carcinoma (RCC) but has been contraindicated in elderly patients. This study assessed the safety and therapeutic efficacy of high-dose IL-2 in patients ≥65 years of age with metastatic melanoma and RCC. Methods: A prospectively collected clinical database of 104 consecutive melanoma or RCC patients treated with high-dose IL-2 between 2009 and 2012 was used to compare clinical outcomes and adverse events in patients ≥65 years of age with those of younger patients. Results: There were 22 (21%) patients ≥65 years and 82 (79%) patients <65 years of age. The mean number of IL-2 doses was lower in older patients during cycle 1 of treatment (7.2 vs. 8.6, p = 0.012). There were no other differences in dosing pattern by age group. There was a higher rate of selected cardiac, constitutional, hematologic, metabolic and renal toxicities in younger patients (p < 0.05). Overall, objective responses and survival were not affected by age, though older patients had a higher partial response rate (p = 0.04). Conclusions: IL-2 is safe and has comparable therapeutic effectiveness in patients ≥65 years. Age should not be considered a contraindication to treatment with IL-2 in otherwise eligible patients.
