文摘
IntroductionThe use of intensity-modulated radiation therapy (IMRT) in rectal cancer has steadily increased over traditional 3D conformal radiotherapy (3D-CRT) due to perceived benefit of delivering higher treatment doses while minimizing exposure to surrounding tissues. However, IMRT is technically challenging and costly, and its effects on rectal cancer outcomes remain unclear.
