Myeloid-dominated “cold” ecosystems blunt antigen handling, phagocytosis, and trafficking, limiting the benefit of immune-checkpoint inhibitors (ICIs). This review focuses on three high-value axes that shape TAM state and niche: the lactate–pH / hypoxia–HIF–VEGF axis that enforces acidic, adenosinergic suppression and angiogenic programs; lipid rafts axis that stabilizes inhibitory hubs (e.g., PI3K–AKT/TREM2) and skews phagocytosis/antigen presentation; and ferroptosis– redox axis control that sets inflammatory versus tolerogenic set-points. The review further outlines pharmacodynamic anchors—hyperpolarized 13C-pyruvate MRI (kPL), soluble ANGPT2, and spatial NT5E/ADORA2A modules—to operationalize a bench-to-biomarker-to-bedside loop using organoid– immune co-cultures, humanized/xenograft systems, and ex vivo tumor slices. This framework prioritizes adaptive enrichment for glycolysis-or adenosine-high tumors, rational timing/sequencing with ICIs, and avoidance of global myelosuppression. Collectively, metabolism-informed TAM re-education offers a route to convert myeloid-dominated “cold” ecosystems into treatment-responsive states across urologic cancers.  \nKeywords: Tumor-associated macrophage; metabolic reprogramming; prostate cancer; bladder cancer; renal cell carcinoma  \n1. Introduction  \nUrologic malignancies, including prostate cancer (PCa), bladder cancer (BCa), and renal cell carcinoma (RCC), represent major contributors to global cancer incidence and mortality[1, 2] . Despite the remarkable success of ICIs across multiple cancer types, response rates remain highly variable between patients inurologic cancers[3] . A substantial fraction of tumors display an immune-excluded or non-inflamed microenvironment characterized by enrichment of immunosuppressive myeloid populations; these tumors less often benefit from immunotherapy[3] . Within this landscape, tumor-associated macrophages  \n(TAMs) constitute a dominant and highly plastic myeloid compartment with a central role in shaping immune tone and treatment responsiveness.  \nMacrophage states are not fixed but are continuously instructed by tumor- and microenvironment-derived cues[4] .
