Various cytokines, including interferon alpha (IFN alpha), tumor necrosis factor alpha (TNF alpha), and granulocyte-macrophage colony-stimulating factor (GM-CSF), have been used as adjuvant therapy for advanced-stage melanoma with some success but with marked toxicity, which appears to be related to higher doses. We investigated the efficacy of IFN alpha, GM-CSF, and TNF alpha in various combinations to induce antitumor and immune responses in a B16F10 murine melanoma model. These studies showed that GM-CSF, IFN alpha, and TNF alpha, when injected together intratumorally, mediated significant inhibition of tumor growth. Tumor regression correlated with local tumor necrosis and significant infiltration of T cells. In addition, this injected intralesional cytokine cocktail also induced lymphadenopathy, with an increase in both CD4(+) and CD8(+) T cells in the draining lymph nodes. Furthermore, tumor-specific CD8(+) T cells were identified from draining lymph nodes. These investigations identify the combined effects of IFN alpha, GM-CSF, and TNF alpha in induction of the adaptive immune response and generation of antigen-specific T-cell reactivity. These results support potential clinical trials of the low-dose cytokine combination as adjuvant therapy for melanoma. (C) 2009 Elsevier Ltd. All rights reserved.
