Abstract Rectal cancer surgery is challenging due to the complex anatomy, making it difficult achieve clear surgical margins. Radiotherapy (RT) plays a crucial role, especially in treating locally recurrent rectal and preserving anal function. However, its effectiveness often limited by tumor hypoxia, particularly prevalent hypoxic regions near bowel wall colorectal cancer. Hypoxia contributes both radiation resistance apoptosis resistance, compromising RT outcomes. To overcome hypoxia‐driven radiotherapy this work designs engineers radiotherapy‐sensitizing bioplatform for efficient RT. It combines lanthanum oxide nanoparticles (La 2 O 3 NPs) with cyanobacteria, which produces oxygen through photosynthesis. This uniquely reduces enhances deposition, improves efficacy. La NPs further enhance reactive species (ROS) production induced radiation, triggering pyroptosis via ROS‐NLRP3‐GSDMD pathway, while amplifies GSDME, circumventing resistance. The integrated thermosensitive hydrogels ensure precise localization of bioplatform, reducing systemic toxicity improving therapeutic specificity. Compared conventional therapies, dual‐action system addresses more effectively. In vivo vitro hypoxia models validate potent anti‐tumor efficacy, offering valuable insights refining clinical treatment paradigms.
