  ABSTRACT: Modern medicine faces the formidable challenge of cancer because of its ability to evade immune surveillance and cultivate resistance to conventional therapies. Cancer cells, when overexpressed with CD47, send a “don’t eat me” signal to macrophages, successfully shielding them from immune destruction. Similarly, tyrosine kinase inhibitors (TKIs) have revolutionized cancer treatment by targeting oncogenic pathways, but their effectiveness is often compromised by resistance and minimal residual disease. This review explores a novel combination of CD47-SIRP-blockade and TKIs, addressing the limitations of monotherapies in cancer treatment. Disrupting the CD47-SIRPα interaction stimulates macrophage-mediated phagocytosis and revives exhausted T cells, while TKIs simultaneously target tumor growth drivers. Confirmation from preclinical studies indicates that this combination is capable of enhancing anti-tumor immunity and remodeling tumor microenvironments for enhanced therapeutic outcomes. However, hematotoxicity and tumor heterogeneity present challenges in the path to clinical translation. This review presents current findings, identifies key research areas, and proposes future directions to enhance this combinatorial approach. In the midst of a new era in cancer treatment, immune modulation combined with targeted therapies promises to offer more effective, less toxic, and personalized treatment options. This combination approach has the potential to significantly improve cancer treatment strategies by overcoming current therapeutic limitations.
