Abstract: The optimal management of T3N0 rectal cancer is an area of active debate that has withstood multiple decades of research. In this comprehensive review, we delve into the many nuances that come with treating T3N0 rectal cancer, particularly examining the role and evolution of radiation therapy. We review both the historical paradigms and latest advances in treatment and highlight the significance of precise preoperative staging. As the field continues to evolve, this review highlights a shift toward more tailored treatments, considering both patient goals and the desire for optimal oncologic outcomes. In the current era, clinical decision-making for T3N0 rectal cancer requires a patient-centric approach that balances effective therapy while minimizing undue side effects.
