Traditional models inadequately mimic human tumor microenvironment (TME) complexity due to interspecies variance, structural simplification, and static perfusion. Vascularized tumor-on-a-chip systems address these gaps by integrating perfusable vasculature with tumor-stroma dynamics in microfluidic environments, enabling dynamic 3D evaluation of drug transport kinetics and therapeutic efficacy. These advances significantly enhance preclinical-to-clinical translatability, though challenges remain in achieving long-term vascular stability and multi-tissue integration under physiological flow conditions. Herein, we summarize recent progress in vascularized tumor-on-a-chip technologies for assessing DDS performance and TME interactions. Finally, opportunities for precision oncology and integrative organ-level modeling are highlighted, underscoring the transformative potential of these platforms in next-generation cancer research.
