Background: In the precheckpoint inhibitor era, high-dose interferon was the only approved adjuvant therapy for high-risk melanoma. In this manuscript, we analyze the recurrence-free survival, overall survival and toxicity profile of adjuvant treatment with interleukin-2 (IL-2) and 5-(3,3-dimethyle-1-triazeno) imidazole-4-carboxamide (DTIC) for resected high-risk melanoma patients. Methods: All patients with stage IIB, IIC or stage III melanoma who were treated with DTIC/IL-2 combination therapy at a single institution from 2000 to 2010 were identified from the University of Louisville Hospital medical record. Patients received 6 months of subcutaneous IL-2 (12 x 10(6) units days 1-4) and intravenous DTIC (750 mg/m(2) day 1 of each cycle) every 28 days for 6 cycles. Individual medical records were accessed to collect the data. Results: Of the 112 patients treated, all underwent surgical resection and then received adjuvant treatment. A total of 58.7% of the patients were male, 42.2% female; 99% were Caucasian. A total of 79 (72.5%) of the patients were alive at the time of analysis and 57 (47.7%) patients were currently event free. A total of 69 (63.3%) patients completed all 6 months of adjuvant combination treatment with 13.8% of the patients requiring IL-2 and 21.1% of the patients requiring DTIC dose reduction. Five year overall survival was 75.57% with recurrence-free survival of 53.05%. Conclusions: For several decades, there has not been an ideal adjuvant treatment for patients with resected high risk melanoma. Our retrospective analysis suggests that combination therapy with DTIC/IL-2 is beneficial and relatively well tolerated as an alternative adjuvant treatment for patients with high-risk melanoma.
