Myeloid cells represent a dominant cellular compartment of tumor lesions and play key roles in tumor inception, progression, metastasis, and response to treatment. Mononuclear phagocytes (MNPs), which include dendritic cells and macrophages, are unique among myeloid cells, as they not only shape both the broader composition and state of the tumor microenvironment but can also specifically instruct cancer-specific, T cell-mediated tumor cell killing, making them especially attractive targets for cancer treatment. Although MNPs remain difficult to modulate therapeutically, our understanding of MNP biology in the antitumor immune response has expanded significantly, offering hope for new possibilities in cancer immunotherapy. Here, we review the recent advances in our study of the cellular identity, molecular diversity, and spatial organization of MNPs in tumors, and we discuss the importance of tailoring therapeutic strategies to incorporate these new insights into cancer treatment design.
