This review summarizes results from major recent trials regarding novel therapeutic agents in melanoma. The topics discussed include targeted therapy with BRAF (V-RAF murine sarcoma viral oncogene homolog B) inhibitors (vemurafenib and dabrafenib), MEK (mitogen-activated protein kinase kinase) inhibitors (trametinib), bcr-abl/c-kit/PDGF-R inhibitors (imatinib), and angiogenesis inhibitors (bevacizumab and aflibercept), as well as immunotherapy with anti-CTLA-4 (anti-cytotoxic T-lymphocyte antigen-4) antibodies (ipilimumab), anti-PD (anti-programmed death receptor) antibodies (nivolumab and lambrolizumab), and anti-PD-L (anti-programmed death ligand) antibodies. Various combinations of these agents, as well as adjunctive GM-CSF (granulocyte-macrophage colony-stimulating factor), T-VEC (talimogene laherparepvec) oncolytic viruses, and novel chemotherapeutic agents, are also described. Despite the tremendous advances that these novel treatments have created, optimal therapeutic agent selection remains a highly individualized decision. Melanoma therapy has vastly progressed since the days when dacarbazine was the sole option for advanced melanoma patients. The molecular understanding of melanoma pathogenesis has yielded a brighter future for advanced melanoma patients.

Granulocyte-macrophage colony-stimulating factor has been widely used as an adjuvant therapy for cancer patients exhibiting myelosuppression induced by chemotherapy or radiotherapy. However, the effects of granulocyte-macrophage colony-stimulating factor on tumor growth, as well as its precise mechanism, are still controversial due to inconsistent evidence. This study investigated the effect of exogenous granulocyte-macrophage colony-stimulating factor on the growth of B16 melanoma, S180 sarcoma, and U14 cervical carcinoma in mice. The angiogenesis and recruitment of bone-marrow-derived cells were analyzed in tumor tissues. Interactions among granulocyte-macrophage colony-stimulating factor, bone-marrow-derived cells, and B16 tumor cells were investigated in vitro. Proangiogenic types of bone-marrow-derived cells in blood were assessed both in vivo and in vitro. The results showed that granulocyte-macrophage colony-stimulating factor markedly facilitated the growth of B16 and S180 tumors, but not U14 tumors. Granulocyte-macrophage colony-stimulating factor increased the densities of blood vessels and the number of bone-marrow-derived cells in B16 tumor tissues. The granulocyte-macrophage colony-stimulating factor-induced enhancement of tumor cell proliferation was mediated by bone-marrow-derived cells in vitro. Meanwhile, a distinct synergistic effect on endothelial cell function between granulocyte-macrophage colony-stimulating factor and bone-marrow-derived cells was observed. After separating two types of bone-marrow-derived cells, granulocyte-macrophage colony-stimulating factor-induced enhancement of tumor growth and angiogenesis in vivo was mediated by proangiogenic cells in granulocytes, but not monocytes, with CD11b+, vascular endothelial growth factor receptor 2, and C-X-C chemokine receptor 4 granulocytes possibly involved. These data suggest that granulocyte-macrophage colony-stimulating factor contributes to the growth and angiogenesis of certain types of tumor, and these mechanisms are probably mediated by proangiogenic cells in granulocytes. Applying granulocyte-macrophage colony-stimulating factor may attenuate the antitumor effects of chemotherapy and radiotherapy in certain types of tumor.
