"MR-guided RT makes it possible to reduce the radiation field for rectal tumors by a third compared with conventional techniques, which may result in less RT-related toxicity and a better quality of life
MR-guided online adaptive radiation therapy (MRgRT) for rectal cancer
Preserve rectum with daily precision
Safely escalate dose for organ preservation
Treatment for rectal cancer typically involves a course of radiation therapy in combination with chemotherapy and/or surgery. Conventional, CBCT-based treatments provide limited image resolution at the time of treatment, requiring the use of large safety margins due to target and OAR motion. This also limits dose escalation and the potential for a complete pathological response.
There is growing interest in MR-guided radiation therapy (MRgRT) to reduce RT-related toxicity and allow dose escalation approaches. This could increase the likelihood of complete clinical response and reduce the need for surgery. With Elekta Unity you can:
Safely escalate dose to the tumor and consider more rectal cancer patients for organ preservation strategies.
