Cancer is a major threat to human health, and radiotherapy is a key treatment method. However, its effectiveness is often limited by tumor radioresistance. The PI3K/AKT/mTOR signaling pathway is commonly dysregulated in cancers and plays a significant role in radioresistance, though its exact mechanisms remain unclear. This review discusses how this pathway regulates tumor radioresistance and highlights recent progress in the development of related inhibitors in preclinical and clinical studies. These findings aim to guide clinical treatment strategies and provide new approaches to overcoming radioresistance.
